The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyrights whatsoever.BACKGROUND OF THE INVENTIONThe invention relates generally to input and output devices for computers. Also, most printing devices may vary in their accuracy, so scaling it up or down slightly may be necessary (download).
In one embodiment, the processor receives telephony signals from the computer and provides telephony signals to the computer, performing the processing necessary to support telephony functions such as conversion of audio signals.
When the user needs to input data, the user has to draw the keyboard out from the keyboard tray below the computer desk. Audio signals from computer sound cards and other audio signal sources may be mixed with telephony signals in keyboards according to the invention. Displays and associated input devices incorporated by the keyboard are provided to control telephony and other keyboard processor functions. In the preferred embodiment, the at least one processor performs other telephony functions such as ring, off-hook, etc. After a long-time operation, it deteriorates the user's visual condition and makes the typing very tiresome.
Furthermore, changing pose to input data generally causes the user to miss some information or fix up with the sequence.
The inventive keyboard includes means for supplying such signals to the same speaker or speakers as audio signals provided by the at least one processor.The audio signals provided by the computer (computer audio signals) and the audio signals provided by the processor (processor audio signals) are preferably mixed prior to being supplied to one or more speakers coupled to the keyboard.
Such arrangement not only affects the quality of entering data, but also hurts the user's vision and sitting pose.In view of these shortcomings, users tend to use a larger computer desk, so that the written information can be put on the desk or the user simply purchases a set of paper holder to clip the document on the desk. However, such larger computer desk does not fit in the place having little room such as school dormitories or small rooms. Such paper holder is installed on the side of a computer monitor; when the user draws out the keyboard key to use the keyboard, there is a distance between the user and the computer monitor, and it is difficult for the user to accurately read the information from the paper next to the monitor, and thus the user usually ahs to lean forward for reading. Such arrangement not only affects the user's sitting pose, but also has negative effects on the user such as leaning too close to the computer monitor and being affected by the radiation.2. If the user needs to write some notes or mark something in the document while entering the data, the user has to take the paper out from the holder, which wastes time and effort.3. The keyboard comprises an array of switches, means for providing signals relating to the state of the switches, one or more processors, and means for providing audio signals to a speaker from audio signals provided by the processor and audio signals provided by the computer.The means for providing signals relating to the state of the switches is provided, for example, by a controller coupled to the switches. Since the paper is clipped onto the adjacent side of the computer monitor and its distance from the user is too far, therefore it usually causes the user to miss some information or fix up with the sequence of the document, and thus affects the quality of inputting data.4.
The signals may indicate, for example, whether individual switches are open or closed by pressing or releasing of keys coupled to the switches. Signals relating to the state of the switches are provided to a computer coupled to the keyboard, either directly by the controller or via the processor, and may be provided to the processor or any other device coupled to the keyboard. Providing telephony functions includes, for example, processing telephony signals from a computer into audio signals and audio signals from a microphone into telephony signals, and optionally provision of ring, off-hook, call waiting, and other signals.


The processor(s) may also receive incoming signals from, for example, a microphone mounted on or otherwise coupled to the keyboard, and provide any addressing and other processing required for delivering the signals in a desired format to the computer, for transmission to other devices, such as for example another computer, linked to the first via a computer network.Keyboard processor(s) according to the invention, may provide other functions.
4 is an illustrative diagram of the present invention when it is in use.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSRefer to FIGS. For example, keyboard processor(s) according to the invention may function in the role of controller for keyboard key switches, and perform the controller function of providing signals relating to the state of the switches to coupled computers or other devices.
1, 2 and 3 for a perspective view, a view of disassembled parts, and a partially enlarged section of the present invention respectively. That is, such processors may comprise or replace the controller.Processors may be used, for example, as one type of means for providing audio signals to a speaker from audio signals provided by the processor and audio signals provided by the computer.
Such arrangement can effectively secure the written information required for the input, save working space of the tabletop of the computer desk, facilitate users to read data from the paper at a short distance, and enable users to input data into the computer accurately. For example, processors may process telephony signals in accordance with Voice Over Internet Protocols (VOIP), Internet Protocols (IP), or any other packet-switched telephony standards.In embodiments of the invention used for network-based telephony, inventive keyboards may use or rely on computers or other devices coupled to the keyboards for connection to the network. When the user no longer uses the holder 2, the user can pull the holder 2 down to hide it in the connecting groove 13 for decoration and storage purposes.Please refer to FIG. For example, in an embodiment used with a workstation or personal computer attached to a network, the keyboard coupled to the computer provides telephony signals to the computer, as for example through an attached cable, a wireless device, or by any other suitable means, and the computer passes the signal, with or without further processing, to the network. In the figure, the paper holder on the keyboard desktop in accordance with the present invention is installed onto a keyboard tray of a sliding mechanical structure 31 below the tabletop of a computer desk 3, and such structure comprises a retaining area 1 for accommodating a keyboard 4 and a holder 2 is installed above the retaining area 1; when the user needs to use the holder 2, the retaining area 1 for accommodating the keyboard 4 is pulled out by means of the sliding mechanical structure 3, and a force is applied on an indention 131 at the edge of the connecting groove 13 to pull the holder 2 upward, so that the holder 2 can be erected and fixed into a position.
Preferably such displays incorporate input devices comprising digitizers, such as touchpads or touchscreens, to provide control signals to the processor and optionally to other devices, such as attached computers or devices attached to or integrated with the keyboard.
A force is applied to an elastic member 24 of the holder 2, so that a cut groove 25, 25? on each side of the elastic member 24 has enough room to let the document or paper be fixed into a clipping section 22. For example, a display incorporating an input device may provide an output related to one or more positions selected on the display by a user of the keyboard, the at least one processor being programmed to process the output of the input device to control at least one telephony, other audio, or other function performed by the at least one processor. A piece of very soft paper 5 can lean against the edge of the tabletop 4 of the computer desk for further support. The paper 5 can be effectively fixed into the clipping section 22 of the holder 2, not just saving working area of the tabletop 4 of the computer desk, but also facilitating users to read the data on the paper 5 at an appropriate distance, and inputting the data into the computer accurately in order to avoid missing information or mixing up with the sequence of the document, which will affect the quality of inputting data. For example, displays used for providing input to telephony processes provided by processors according to the invention may provide modes for reviewing and selecting intended addressees, or recipients for messages, completing and timing the sending, acknowledgement, and receipt of message, and other functions. For example, displayed lists of addressees may be presented on the display screen, the selection of one or more of which causes the processor to provide signals to a computer coupled to the keyboard with signals for establishing a connection with or delivering communications to the selected addressees.
If the user forgets to pull the holder back into the connecting groove 1 before pushing the retaining area 1 of the keyboard tray back under the tabletop of the computer desk 4, the skid-proof pad can prevent the keyboard 4 from sliding or hitting the holder structure 2 due to the pushing force or damaging or loosening the holder structure 2.Furthermore, since the holder 2 and the connecting groove 13 are pivotally coupled, therefore the holder 2 can be pulled inward or outward to facilitate the user to use and store the holder 2.
Selection of menus and items within menus, or the designation of icons, may be assisted through the provision of dedicated control switches such as buttons coupled to the displays, or through the use of touchpad type systems.As discussed above, keyboards according to the invention may be coupled to computers which provide non-telephony audio signals as well as telephony signals. Moreover, the indention 131 of the holder 2 enables the user to apply force to pull the holder 2 easily. For example, computers may provide Voice Over Internet Protocol or other telephony signals received, for example, over a computer network such as the Internet. After the holder 2 is pulled downward, the open end of the holder 2 and the retaining area are placed horizontally and engaged completely for its accommodation.
Such computers may also provide non-telephony signals such as voice e-mail, music, warning tones and aural indicators, and multimedia.
Such design can keep the artistic look of the overall structure and also can serve as a decoration as well.Further, an end of the retaining area 1 has an ergonomic support section 11, and a glove compartment 111 with a movable lid 112 pivotally coupled to the interior of the support section 11.
Such arrangement not only lets users use the keyboard while resting their palms and wrists on the support section 11 comfortably, but also lets user put objects such as stationeries, watch, or calculator (not shown in the figure) in the glove compartment 111 for storage and use.Those skilled in the art will readily recognize that these and various other modifications and changes may be made to the present invention without strictly following the exemplary application illustrated and described herein and without departing from the true spirit and scope of the present invention, which is set forth in the following claims.
For example, preferred embodiments of the invention comprise audio circuits capable of mixing telephony signals originating from microphones, telephone handsets, and other devices attached to the keyboard with audio signals received from the computer, such as multimedia sound tracks or music, amplifying them, and providing them simultaneously to the speaker(s). For example, a telephony signal received by the keyboard from the computer may be mixed with music, voice, or other non-telephony signals received from the computer, such as for example audio signals processed by the computer's operating system. As discussed above, keyboards according to the invention may process both telephony and other signals by, for example, mixing one or more of each type of signal to provide simultaneous output to a speaker, or by interrupting the output or other processing of one type of signal for processing of another.Keyboards according to the invention may comprise one or more speakers mounted to or otherwise coupled to the keyboard, as for example by providing a permanently mounted speaker in a keyboard body or chassis, or by providing external speakers coupled to the keyboard and the keyboard's audio circuit by plugs or jacks, or other removable connectors. In one embodiment, the keyboard is provided with a plurality of speakers, including one or more speakers mounted at the ends of the keyboard and facing outward, away from the center of the keyboard in a lateral direction.
In some embodiments the microphone is mounted in the keyboard, in proximity to a visual indicator device such as a light, the visual indicator device controlled by the keyboard processor(s) to provide a visual indication when audio signals from the microphone will be processed by the processor to provide the at least one function. Optionally, visual indicator devices may be used to aid users of the microphones in locating the microphones in the keyboards and to thereby improve the quality of audio signals received by the microphones and subsequent processing of the signals.
Lights suitable for use as visual indicator devices in accordance with such embodiments include light-emitting diodes (LEDs) and other light-emitting devices. For example, telephone handsets comprising at least microphones and speakers may be coupled to or mounted on the keyboard, or provided as integral portions of the keyboard, as for example by co-molding processes in forming the keyboards. Coupled telephone sets may include handset cradles mounted to or on the keyboard.Keyboards according to the invention may comprise systems and devices for controlling access to computers coupled to the keyboards.
For example, a fingerprint sampling device may be included within a token such as a small, easily carryable, dockable casing, with an associate processor and suitable connectors, the token being removably attachable to the keyboard so that the fingerprint sampling device is accessible by a user seeking access to the computer when the token is attached to the keyboard.Keyboards according to the invention may further comprise visual indicator devices to display a first indication when access to a computer has been granted to a user, based for example upon a comparison of previously-acquired fingerprint or other biometric data to data acquired from the user by the fingerprint sampling device, and to display a second indication when such access has been denied. For example, indicator lights such as LEDs are mounted to the keyboard, either as part of the access control system separately, and show red when access is denied, and green when access is authorized.In an embodiment of a keyboard according to the invention, a fingerprint or other biometric sampling device for authorizing access by a user to a computer is permanently mounted to or removably coupled to the keyboard, and has a preferred orientation relative to a thumb, finger, or other digit or other sample source intended to be placed upon or in a specified relation to a surface of the fingerprint sampling device for sampling, the preferred orientation being definable by a principle axis. The sampling device is mounted on the keyboard at an edge of the keyboard which, preferably along the side of the keyboard, such that, for example, when the keyboard is in normal intended use by a user, the edge is substantially parallel to a forearm of the user, and is oriented on the keyboard at an angle so as to ease use of the device by users situated for use of the keyboard. For example, the device is mounted so as to align comfortably with the digit the user is intended to use in accessing the computer, when the digit is held in a natural or comfortable position compatible with the requirements of the sampling device. For example, the device is mounted to the keyboard such that the principal axis of the device is aligned at an angle of about 15 degrees to about 120 degrees from the edge of the keyboard. For a device intended to operate with a user's thumb, the device may be located on the side of the keyboard corresponding to the thumb the user intends to use, and angled at about 40 to about 90 degrees from the edge or the side of the keyboard.Keyboards according to the invention which comprise fingerprint and other contact-type biometric sampling systems may also comprise surfaces composed at least partly of electrical conductive materials, the surfaces configured to as to improve an electrical connection between the fingerprint sampling system and one or more portions of a user's body. For example, improved electrical contact between the sampling device and portions of a user's hand may be used to improve the quality and reliability of fingerprint sampling systems. In a preferred configuration, such keyboards according to the invention comprise trimwork or other surface work of chrome or other metals or conductors, the conductor(s) located so as to contact a portion of a user's hand, for example, trimwork or other surface work on the end of the keyboard intended to be contacted by the hand including the sampled digit.In some embodiments, the processor(s) provides additional or alternative-style telephony functions. Such functions may include, for example, “squawk” communications or other direct, sometimes one-way communications between computers. Among differences sometimes associated with such communications, relative to other telephony, are that normal “dialing” or addressing procedures are often abbreviated or eliminated, as for example by providing a reduced set of possible addressees, or by simplifying functions used in addressing communications. In addition, the process of notifying the intended addressee of the delivery or attempted delivery of the communication, and waiting for the addressee to respond or otherwise acknowledge prior to delivering the message, may be reduced or eliminated.
For example, in traditional telephone protocols the presence of a message is announced by the “ringing” of the telephone, and the message is not delivered until the telephone is answered.
This is particularly true where communications are one-way, as outside the context of a live conversation it may not be possible to detect brief delays in the delivery of messages.In some embodiments of the invention audio signals received from a computer coupled to a keyboard according to the invention are provided to speakers coupled to the keyboard.
Such audio signals may be mixed with and delivered to one or more speakers with telephony signals processed by a telephony processor in the keyboard, or they may be delivered sequentially to a single speaker or set of speakers, or simultaneously to separate speakers. For example, some embodiments comprise a mouse, trackball, touchpad, or other pointing devices coupled to the keyboard and through the keyboard to a computer. In preferred embodiments of this type, the pointing device is coupled to the computer through more than one circuit or connection.


For example, in a keyboard comprising a hub connection such as a USB hub, a pointing device is coupled to the computer both through the hub, and through a separate coupling to the computer, as for example an automatic switch. The invention may be implemented with a wide variety of key arrangements, including QWERTY, the Dvorak scheme, and others. Keyboards may comprise, for example, at least one separate key for each alphanumeric character, including for example shift keys to enable inputting of lower and upper case characters, and for any other desired editing or writing symbol or special function.Processors, controllers, and other devices incorporated within or otherwise coupled to keyboards according to the invention may be powered by power supplies mounted to the keyboard or coupled to the keyboard via connectors or other devices. 1 is a schematic perspective view of an embodiment of a keyboard according to the invention.FIG. 2 is a schematic view of a computer system comprising a plurality of keyboards according to the invention.FIG. 5a and 5b provide a schematic diagram of an embodiment of a processor suitable for implementation in keyboards according to the invention.FIG. 6 is a schematic diagram of a memory suitable for implementation in keyboards according to the invention.FIG. 7 is a schematic diagram of an embodiment of a uniform serial bus interface suitable for implementation in keyboards according to the invention.FIG. 8 is a schematic diagram of an embodiment of a display interface suitable for implementation in keyboards according to the invention.FIG. 9 is a schematic diagram of an embodiment of a display input device interface suitable for implementation in keyboards according to the invention.FIG.
10 is a schematic diagram of embodiments of audio mixer, amplifier, and telephone handset interfaces suitable for implementation in keyboards according to the invention.DETAILED DESCRIPTION OF PREFERRED EMBODIMENTSFIG. One way in which this may be accomplished is through the operation of keys 101 and their associated switches. Pressing keys 101 in various sequences and combinations may be used to send commands, data, and other information to computer(s) coupled to the keyboard, for processing either by the computer(s) coupled directly to the keyboard or by other computers linked to the keyboard through such computer(s).
For example, activation of “MESSAGE” key 356 at a time when indicator light 357 is illuminated retrieves new e-mail messages addressed to the user logged in at keyboard 100, indicator light 357 being illuminated on command of processor 401 or other processor upon receipt of a new e-mail. The volume of speakers mounted on or coupled to keyboard 100 may be increased by activating key 358, and decreased by activating key 359.Keyboard 100 of FIG. 3 further comprises, inter alia, infrared sensor 306, for use in wireless communications between the keyboard and pointing or other devices supported by the keyboard.FIG. 1, 3) in groups 301, 303, 304, 305, to provide signals relating to the state of the switches to processors 401, 402, to any computer(s) coupled to the keyboard, and to any other desired devices. A large number of key—switch—controller combinations suitable for incorporation in keyboards for controlling computers according to the invention are available commercially, from sources such as, for example, Advanced Input Devices of Coeur D'Alene, Id.
As will be appreciated by those skilled in the art, such combinations may also be made specially for the purpose, incorporating technologies such as application-specific integrated circuits (ASICs). 4, a plurality of general- and special-purpose processors 412, 413 provide functions related to general process controls and telephony, including providing audio signals to the audio circuit from telephony signals provided by the computer, and providing telephony signals for output to the computer from audio signals provided by a microphone, and providing audio signals from telephony signals provided by the computer. A suitable processor 412 for use in supporting telephony functions in keyboards according to the invention comprises a combination of a T8301 Internet Protocol (IP) telephone digital signal processor (DSP) available from Lucent Technologies of Allentown, Pa. Functional descriptions and diagrams of the DSP1627 processor are given in the “DSP1627 Digital Signal Processor” Data Sheet, document DS00-205 WTEC, published March 2000 by Lucent Technologies of Allentown, Pa.Optionally, processing unit or processor 401 comprises one or more suitable processors and serves the functions of controller 400 for the key—switch matrix of the keyboard. That is, processor 401 comprises the controller, and is F coupled to the switches to perform the controller function of providing signals relating to the state of the switches.Keyboards according to the invention may provide telephony functions to support any type of computer-supported telephony. Upon receipt by processor 401 of a call-answered indication sent, for example, by the addressee's computer or telephone upon picking up of a corresponding handset or entry of a suitable computer command by the addressee, processor 401 activates handset microphone 403.
As the calling user speaks into microphone 403, audio signals produced by microphone 403 are processed by processor 401 into telephony signals and provided to a the user's computer, with an address supplied by processor 401. Upon receipt of telephony signals from the computer, processor 401 provides corresponding audio signals to a handset speaker 402.
Replacing handset 104 in handset cradle 105 activates a switch, generating a call terminated signal which is provided to the computer and forwarded to the addressee.Alternatively, or in addition, keyboards and processors 401 according to the invention may support such telephony functions as “squawk” communications, which are similar to standard telephony, but without some features such as, for example, call-received (or “ringing” functions), and in some cases simplified or abbreviated addressing or dialing functions. Upon selection of an address and entry of an execution command entered by the user at the keyboard, as for example by activation of a switch 107 or “SQWK” button 355 in FIG.
3, processor 401 activates a microphone 103 mounted to keyboard 100, and, optionally, an indicator 108, indicating that microphone 103 is active and showing the user its location. When the user speaks into microphone 103, a corresponding audio signal is provided by the microphone to processor 401, which generates a corresponding telephony signal. The generated telephony signal is provided, with a suitable address tag, to the computer and forwarded to the addressee's system, where it is provided to the addressee's processor, converted back into a corresponding audio signal, and provided to a speaker on the addressee's system, optionally without waiting for an acknowledgement or authorization by the addressee. A suitable USB hub for use in keyboards according to the invention is the TUSB2077A 7-Port Universal Serial Bus available from Texas Instruments of Dallas, Tex. USB Host interface 700 comprises couplings 450 for external USB ports, for coupling external devices to keyboard 100, and couplings for external pointing device 112, biometric access device 111, and key switch controller 400.USB hub 410 also serves as an alternate coupling between an external pointing device such as mouse 212 and a computer coupled to the keyboard 100. External pointing device 212 may also be coupled through coupling 420, including optional autoswitch 421, which provides optional paths for input to keyboard 100 and a computer coupled thereto.Mixer 404 processes audio signals from processor 401 and, via coupling 422, audio signals provided from a computer coupled to keyboard 100. Mixer 404 mixes audio signals in any desired manner, for example by amplifying one or more sets relative to others, or by interrupting one set during processing of another, or by mixing them as received, without amplification. In some operating modes, as commanded by processor 401, audio signals such as music provided by a computer via coupling 422 are interrupted while audio signals such as telephony signals processed by processor 401 are received from processor 401. In one embodiment it has been found advantageous to mix signals corresponding to telephony signals processed by processor 401 at an amplification of three times that used for audio signals received from a computer via coupling 422.One or more amplifier(s) 405 may be provided to provide any further desired amplification, such as via speaker volume controls implemented by a user of display 106 and associated switches 107 or a key array such as array 305. 1) is mounted in proximity to a visual indicator device such as a light-emitting diode (LED) controlled, by processor 401 for providing a visual indication when audio signals from the microphone will be processed by the processor to provide the at least one function, that is, when the microphone is ready to receive audio input from a user. In addition to providing an indication of microphone and processor readiness, the visual indicator device may be used to provide a convenient locator reference for a user of the microphone. For example, by placing the indicator device close to or at least partially surrounding the microphone, a user may be guided to speaking into the microphone while sending telephony messages.A suitable microphone for mounting to a keyboard or use in an external stand, according to the invention, is the Omnidirectional Electret Condenser Microphone, WM0934B, DB, C, or D, available from Panasonic. Principal axis 122 is oriented at an angle 125 of about 65 degrees from edge 124 of keyboard 100, in order to facilitate comfortable and effective scanning of an image of a user's right thumb. Due to the orientation of device 111, 430 on the upper surface of keyboard 100, the user is able to do so in a manner which promotes fast and effective image scanning, at minimal discomfort and inconvenience to the user.Keyboard 100 further comprises visual indicator device 126 to display a first indication when access to a computer has been granted to a user based upon a comparison of previously-acquired fingerprint data to data acquired from the user by the fingerprint sampling device, and to display a second indication when said access has been denied.
1) fabricated at least partially from electrically conductive material such as chrome or many other metals, the electrically conductive material being electrically coupled to the biometric sampling device 111 so as to improve an electrical connection between the fingerprint sampling system and at least a portion of a user's body when the user is in contact with the keyboard. This electrical contact thus established between the user and device 111 has been found, for example, to improve the efficiency and reliability of access device 111.While the invention has been described and illustrated in connection with preferred embodiments, many variations and modifications as will be evident to those skilled in this art may be made without departing from the spirit and scope of the invention, and the invention is thus not to be limited to the precise details of methodology or construction set forth above as such variations and modifications are intended to be included within the scope of the invention. Except to the extent necessary or inherent in the processes themselves, no particular order to steps or stages of methods or processes described in this disclosure, including the Figures, is implied. In many cases the order of process steps may be varied without changing the purpose, effect, or import of the methods described.
