  • Patent number: 8821049
    Abstract: An electrically-assisted mechanical Braille writer includes a main solenoid to apply force to emboss Braille onto a printing medium, and advance an embossing mechanism to the next cell. A second solenoid engages a mechanical stop to prevent one or more embossing keys from being fully depressed, to prevent kickback from the keys mechanically coupling to the main solenoid. In unpowered operation, the mechanical stop is disengaged, and the embossing keys may be fully depressed to apply force to emboss Braille and advance the embossing mechanism. Accordingly, with electrical power, the user may supply a lesser amount of force and still fully emboss Braille cells, while without electrical power, the Braille writer remains fully operational.

    Abstract: Optics are utilized in an input device such as a mouse or keyboard, for example, to detect a condition of one or more selection indicators, such as whether a key or button has been depressed or a scroll wheel has been rotated. Depressing a key, clicking a button and/or rotating a scroll wheel cause one or more optical signals to be reflected from the corresponding selection indicator onto an optical detector. The optical detector generates electrical signals in response to the light received by the optical detector. A computational device of the input device processes the electrical signals to determine whether a key or button has been depressed, whether a scroll wheel has been rotated, etc. The corresponding information is then input to a computer that is interfaced with the input device.

    Abstract: The method for automatic determination of validity or invalidity of input from miniaturized keypads or keyboards, in which more than one key is operated at the same time, includes designating a number of keys as principal keys and assigning each key neighboring each principal key as nearest neighbor or next nearest neighbor and then testing each signal produced by key operation. The signal is valid if it is produced by operation of only one single key. However testing continues if two or more keys produce the signal. Then the signal is valid when the two or more keys are correlated in an unambiguous principal key-nearest neighbor key relationship. If not, testing continues further and the signal is valid if the plural keys are correlated in an unambiguous principal key-nearest neighbor key-next nearest neighbor key relationship. Otherwise the signal is an invalid key input.

    Abstract: Embodiments of the present invention are directed to a computer keyboard having a key sensing device that provides two levels of sensing by generating electrical signals depending on the force applied on the keys. The different levels of key sensing can be used to provide different functions, for instance, in a software application. This key sensing functionality can be provided on all or only some of the keys of the keyboard. For example, the different pressure levels applied on the key can be used to control cursor movement or scrolling and to produce pressure-based shifting between lower case and upper case. A method of providing pressure sensitive key functionalities for a keyboard comprises producing a signal by applying a pressure to a key which is configured to produce different signals in response to different pressure levels applied to the key. A user interface response is generated based on the signal produced by the pressure applied to the key.

This structure prevents the print key from triggering a print operation if it is accidentally pressed.

  • Patent number: 6515653
    Abstract: A keyboard control system that contains a manufacturer's identification code and a multiple selection matrix. This invention utilizes all the existing LED leads on a keyboard controller. Using the period between initial setting and normal operation together with triggering signals, user or customer is able to pick up suitable data from a single keyboard controller. In addition, the invention is capable of using the same leads for connecting to external serial EEPROM so that new data not included among the preset data within the keyboard controller can still be input to the controller. Furthermore, the same type of technique can be used to increase the number of combinations in different application areas as long as more keyboard controller input/output ports are available.

    Abstract: A keyboard having an improved function key section and an improved editing section. A row of keys is located behind the alphanumeric section. The row of keys includes individual predefined command keys. The groupings of the predefined command keys may be made based on the functionality of the keys, their use on common applications or programs, and/or other by other grouping techniques. Further, the keys within each group may be ordered based on chronological order of use, frequency of use, or by a correlation to a graphical toolbar. Each of at least two adjacent groupings of keys behind the alphanumeric region consists of exactly three keys, and each of at least three adjacent key groupings in the entire row consists of exactly three keys. The keys are each capable of functioning as predetermined command keys in a first mode and standard function keys in a second mode.

  • Patent number: 6439785
    Abstract: A keyboard includes a keyboard body similar to a traditional keyboard. The keyboard body has an edge from which an additional portion extends. The portion has a top face on which an EL panel or a thin plate having patterns and/or figures printed thereon is placed. A transparent cover is openably attached to the portion for covering the top face and thus housing the EL panel or the thin plate. The cover may be hinged to the portion whereby it is movable between a closed position and an open position. Alternatively, the cover is releasably attached to the portion whereby the cover can be removed for replacing a new EL panel or a new thin plate having different patterns printed thereon. The EL panel or the printed thin plate serves the purpose of decoration and enhances the appeal of the keyboard to the general consumers.

  • Patent number: 6215418
    Abstract: A programmable membrane switch input/output system is described. The system includes a membrane switch having a matrix layout embedded in a plastic film with a plurality of switches located at specific locations on the film. Output lines from the matrix layout are electrically connectable to a conversion unit which converts the output signals from a first code dependent on the matrix layout and the position of the switches to a second code which is independent of the position of the switches and the matrix layout. The conversion unit can convert the output signals into a serial code which can be transmitted serially from the conversion unit to a processing device located remotely from the membrane switch. By transferring the output signal serially from the conversion unit to the processing device, the cable can have fewer lines and less space is taken on the processing device for the connection.

  • Patent number: 5969645
    Abstract: A microcomputer has an output port and an input port. A plurality of switches are provided between and matrix-connected to respective bits of the output port and respective bits of the input port. The microcomputer renders all of the bits of the output port in an output state, and in this state, checks whether an output of the output port is obtained at one of the bits of the input port. When an output of the output port is obtained at one of the bits of the input port, data indicating a manipulated one of the plurality of switches is acquired by rendering, in order, the bits of the output port in an output state, and then the process of acquiring data indicating a manipulated switch is again executed after a lapse of a predetermined amount of time. The acquired data is made effective if a first acquired data and a second acquired data are identical.
