The adaptation circuit exponentially converts a voltage which is proportional to the average of a time duration of an overload control signal to an adaptation current which is averaged and converted to an adaptation voltage. An integrator circuit includes a sole switch which shorts to ground a circuit point for generating an analog signal formed of line segments; each segment has a slope magnitude controllable by the adaptation voltage.

摘要： The present invention relates to a motor vehicle mounted directional microphone assembly for use in hands-free cellular telecommunications. The microphone assembly is comprised of a case and a removable directional microphone module. The case is adapted to mount and lock the module in a plurality of different orientations, thereby enabling the assembly to accommodate various mounting arrangements within the vehicle. The module is releasable, however, from its locked position to permit re-orientation of the microphone with respect to the case, if desired. The module is also completely removable from the case to permit mounting of the module within the vehicle in mounting arrangements independent of the case.

摘要： An automatic microphone control system particularly suited to controlling a small, predetermined number of microphones. A representation of the level of a microphone signal is compared individually to the level representations of each of the other microphones to determine if the microphone should receive a gating trigger. If the microphone level compares favorably to each of the other microphones, and a noise adaptive threshold comparison criterion is also satisfied, then the microphone receives a gating trigger. This triggers a gate ON action for the microphone, which is held at least 0.4 seconds by a one-shot and also locked ON unless a gate ON action is initiated by any other microphone. The circuitry for a two-microphone system particularly suited to a lectern application is powerable by a conventional phantom-powering balanced microphone preamplifier input.

摘要： A teleconferencing system for connection to telephone lines or other communication links. Directionally gated microphones receive local speech for audio send signal transmission to the far end on the telephone line, and audio receive signals from the far end are output locally via a loudspeaker. The outgoing send signals and incoming receive signals are automatically suppressed in accordance with user and setup controls (volume and suppression) and in accordance with the strength of the incoming receive signal. When the system is in a send mode, the receive signals are suppressed to a lower audible level; when the system is in a receive mode, the send signals are suppressed. The mode of the system is switched during conversation. When simultaneous talking (speech from both ends) occurs, priority is given to the interrupting party.
