Abstract: A hand microphone and an adaptor module form an assembly which is a peripheral device for a personal computer. The hand microphone is used to control dictation functions to be carried out by the PC. Two separate analog control signal channels are output from the hand microphone and applied, respectively, as X- and Y-axis inputs for the game port on the PC. Control signals carried in the two signal channels are generated by actuating control switches mounted on the hand microphone.

Abstract: A method and apparatus for indicating the number of the particular message that has been reached on a bi-directionally movable record medium used with a record/playback device. A position count is incremented and decremented as the record medium moves in forward and reverse directions, respectively; and end-of-message counts representing the locations of the ends of messages relative to an arbitrary reference location of the record medium are stored. Information representing the number of each message whose end-of-message count is stored is provided; and the number of the message which has been reached is determined as a function of which stored end-of-message count is greater than the present position count and which stored end-of-message count is less than that position count.

Abstract: A variable mode numerical display for a record/playback device normally displays a numerical count representing the present position of the record medium used with that device and is operable to interrupt this normal display so as to display the number of a message that was last-recorded or that is in position for playback or to display the number of an instruction that was last-recorded or that has been reached. Also, a bar graph display is comprised of plural visual display elements which are selectively energized as a function of the interval that separates successive pulses that are generated in conjunction with the movement of the record medium. The variable mode and bar graph displays are controlled by a processor.

Abstract: A record and/or playback device whose operating mode is controlled by processor apparatus which is responsive to the selected operation of various operating control switches. The processor apparatus includes a sensor for sensing when the device is in an inactive mode, such as a "stop" mode, a timer for determining when the device has remained in this inactive mode for a predetermined time, and means responsive to the timer for disposing the device in a dormant condition in which it does not respond to the operation of the operating control switches. Furthermore, the processor apparatus comprises a microprocessor which includes a counter that is incremented when the record medium of the device is moved, and a memory for storing respective counts corresponding to locations of the record medium at which "cue" signals are recorded.

Abstract: A storage medium in which previously recorded messages are stored is scanned for instruction signals representing the occurrences of instructions in those messages. Following the aforementioned scanning, if a message in condition to be played back includes an instruction, a suitable display is provided. Another display is provided if any further messages, not yet in condition to be played back, include instructions.
