Title: Safety telephone set for transmitting and receiving speech in motor vehicles and cabins
IPC: B60R11/00
Filed: 1993-06-24
Abstract: With the telephone set for motor vehicles and cabins, voice and tones can be received and transmitted by the arrangement of isolated units in ergonomic positions in relation to the hands, ears and mouth: console (keypad/controls, between the two front seats, or on a retractible arm rest between passengers on the rear seat; and also to the side or in front of the cabin occupant); connects with the transceiver unit and battery system of the permanently installed/car/mobile telephone or with a "walkie-talkie"-type broadcast receiver and transmitter; at least one microphone within the speaking range of the driver, the front-seat passenger and the rear-seat passenger; and at least one loudspeaker within the hearing range of the driver, the front-seat passenger and the rear-seat passenger.

Patent DE-4425905-A1 (DE)
Inventor: BALD HUBERT DIPL ING
IPC: B06B1/16
Filed: 1994-07-21
Abstract: A device and process are proposed for compensating for transverse vibrations in vibrators with a predetermined direction of vibration. Transverse vibrations in vibrators may be undesirable. To compensate for, or at least reduce, transverse vibrations, the proposed solution uses an active method: the transverse vibrations are measured as vibration path components or, in the case of the associated phenomenon of the directional deviation of the driving force, as deviations of the angles of rotation of the unbalanced mass from their preset position. On the basis of these measurements, the energy applied to the drive motors is adjusted using a suitable adjusting element, thereby, by appropriate torque adjustment, altering the resulting driving force so as to reduce the transverse vibrations. The proposed device and process can be used especially with vibrators which use so-called self-synchronisation.
