Means For Selectively Rendering Key Operable Or Inoperable Patents (Class 434/229)
  • Patent number: 6142910
    Abstract: A method and therapy software system for preventing computer operator injuries combines a computer with a software system and prevents or rehabilitates computer operator injuries resulting from the prolonged use of a computer keyboard or mouse associated with the computer by reminding said computer operator to perform physical therapy exercises that are designed to reduce the potential injuries that can result from prolonged uninterrupted use of a computer keyboard or mouse.

  • Patent number: 5868647
    Abstract: An apparatus and method for reducing, preventing, lessening and treating the incidence and severity of Repetitive Strain Injuries ("RSI") comprising a combination of computer software and hardware that provides a "prompt" and system whereby the computer operator exercises their upper extremities during data entry and word processing thereby maximizing the excursion (range of motion) of the joints involved directly and indirectly in computer operation. In summary, the apparatus and method of the present invention includes 1) specialized target means with optional counters which serves as "goals" or marks towards which the hands of the typist are directed during prolonged key entry, 2) software that directs the movement of the limbs to and from the keyboard, and 3) software that individualizes the frequency and intensity of the exercise sequence.

  • Patent number: 5792025
    Abstract: A system to reducing repetitive motion injury (RMI) risks comprises a wrist-resting device having one or both of a heater and a vibrator in the device. In preferred embodiments edges of a support pad for the device are rounded significantly to avoid the possibility of sharp edges impeding a user's blood circulation. In another aspect a control system is provided for monitoring user activity and weighting each instance of activity according to stored parameters to accumulate data on user stress level. In the event a prestored stress threshold is reached, a media player is invoked to provide rest and exercise for the user.

  • Patent number: 5214429
    Abstract: An adapter device for use with a data-input-type keyboard comprises a housing defining a chamber receiving the keyboard. An upper housing panel is provided with a first opening at least coextensive with all keys on said keyboard. A plate is hingedly secured to the upper panel so that the plate covers the first opening in an access restriction or limited use position of the plate. The plate is provided with an opening at least coextensive with a predetermined set of keys, fewer than all of the keys of the keyboard. The device further comprises an alignment component for locating the housing relative to the keyboard so that the keyboard occupies a predetermined position relative to the housing and so that the second predetermined set of keys is aligned with the opening.

  • Patent number: 5096317
    Abstract: A cover apparatus including a transparent housing overlying a computer keyboard, wherein the cover apparatus includes a plurality of forward and rear side walls defining rows of openings, wherein each row of openings is arranged overlying rows of computer keys. The openings are provided with cover housings to selectively cover individual or the plurality of keys, wherein each of the plurality of keys of the computer keyboard is positioned within the openings to provide selective covering thereof to minimize inadvertent pressing of such keys in usage of the keyboard.

  • Patent number: 5047952
    Abstract: A communication system for deaf, deaf-blind, or non-vocal individuals includes an instrumented glove for obtaining electrical signals indicative of a hand configuration of a first individual. Strain gage sensors in the glove flex with movement of the hand. Each sensor includes a tension strain gage and a compression strain gage which are serially connected and form two legs in a bridge circuit. Signals from the bridge circuit are amplified and digitized and applied to a computer which includes an adaptive pattern recognition algorithm which is responsive to hand-state vectors for recognizing letter beacons in hand-space. A second individual communicates with the first individual through the computer system using a portable keyboard. The output devices for communicating to the first and second individuals depend on the visual, vocal and hearing capabilities of the individuals and can be selected from a voice synthesizer, LCD monitor, or braille display.

  • Patent number: 4414537
    Abstract: A man-machine interface is disclosed for translating discrete hand positions into electrical signals representing alpha-numeric characters. The interface comprises a glove having sensors positioned with respect to the hand for detecting the flex of finger joints and sensors for detecting the contact between various portions of the hand. Additional sensors detect the movement of the hand with respect to a gravitational vector and a horizontal plane of reference. Further additional sensors detect the twisting and flexing of the wrist. The additional sensors are associated with prescribed mode signals which determine whether subsequently formed or priorly formed character specifying hand positions are to be entered for transmission. The alpha-numeric characters associated with the formed character specifying hand positions are transmitted only when the appropriate mode signal results.

  • Patent number: 4398086
    Abstract: A game-calculator having a single housing for a handheld calculator and an electronic game each sharing the same display, with a sliding mask to alternatively cover in a first or second position either the calculator keyboard input keys, or both the game input keys and that portion of the display panel not used to display the calculator functions, with the slide also serving to position a switch which is coupled to the programmed data processor, responsive to movement of the slide from the first position to the second position, or vice versa.
