MECHANISM FOR THE AUTOMATIC REVERSAL OF THE MODE OF OPERATION OF A RECORDING DEVICE, A TRANSMITTER OR A TRANSCEIVER.
PATENT CLAIMS 1st control equipment in a Anfzeichnungsgerät, a transmitter or a transceiver, which exhibit a vibration microphone for the admission of by bone line of transferred speech signals as well as Schaltmittel to the release of control procedures, by the fact characterized that in the control equipment an entry stage and a switching control are present, whereby the entry stage either a) over an amplifier (3) with the vibration microphone planned for the admission of the speech signals (1) verbunlo denes Tiefoder bandpass filter (5), of the microphone carrier by Gegeneinanderschlagen of the teeth produced impact vibrations lets and speech signals through suppressed, or b) a second vibration microphone (lA), of the microphone carrier by Gegeneinanderschlagen of the teeth produced impact vibrations lets and speech signals through suppressed, exhibit and with the switching control (6, 6 ") it is connected which delivers itself with each Gegeneinanderschlagen of the teeth cyclically changing control signals, and that the switching control (6, 6 ") with the Schaltmitteln (4; 4A; 9; 9A, 9B) connected ist.
2. Control equipment in a recording device after patent claim 1, by the fact characterized that the switching control (6, 6 ") delivers first and a second control signal, whereby the switching control (6, 6 ') is so implemented that the reversal of recording on recording end according to the order of the occurrence of the first and second control signal abweehslungsweise by first and the second control signal erfolgt.
3. Control equipment after patent claim 2, by it characterized that the switching control (6, 6 ") delivers a third Stenersignal, by which arranges a rewinding of a recording volume wird.
4. Control equipment after patent claim 3, by it characterized that the switching control (6, 6 ') emits a fourth a5 control signal, by which arranges the rendition of the recording wird.
Steuereinñchtung in a transmitter after patent claim 1, by the fact characterized that the switching control (6, 6 ') delivers first and a second control signal, whereby the Sehaltersteuerung (6, 6 ") is so implemented that the reversal of introducing and completion of a transmission procedure according to the order of the occurrence of the first and second control signals abwechslungsweise by the first and second control signal erfolgt.
6. Control equipment in one Sene /Empfangsgerät after A system to automatically control the changeover of recording and recording stop, or transmission and transmission stop, and being employed in the recording or transmitting device provided with a vibration pick-up type microphone for picking up bone-conducted voice sounds. The automatic changeover of recording and recording stop or transmission and transmission stop is attained by control signals corresponding to impact vibrations except voice signals uttered by a microphone wearer himself, transmitted through his bones and picked up by the microphone or another controlling microphone. 1. In an automatic transmission and reception control system for a transmitting and receiving device including a vibration pick-up type microphone for picking up bone-conducted voice signals, a speaker for hearing received voice sounds, and means for switching over between transmission and reception; the improvement comprising means coupled to said microphone for producing control signals from impact vibrations except voice signals uttered by a microphone wearer himself, transmitted through his bones and picked up by the microphone, and that said switching means comprises means responsive to said signals for alternately switching between transmission and reception according to the input order in which control signals are applied. 2. A system according to claim 1 comprising a second vibration pick-up type microphone arranged to pick up impact vibrations for voice transmission. 3. A system according to claim 1 wherein said microphone is arranged to be responsive to impact vibrations generated when the microphone wearer strikes his lower teeth against upper ones. 4. A system according to claim 1 comprising visible display means connected to display the transmission or reception state of said system.
