Remote microphone and range-finding configurations
First Claim
1. Picture and sound recording apparatus, comprising:
- (a) a camera, including;
means for recording a picture and audio information,a receiver to receive a wireless signal carrying the audio information, anda docking station to physically receive a remote unit, the docking station including an electrical contact to receive a hardwired signal carrying the audio information; and
(b) the remote unit, including;
a microphone to detect the audio information,a modulator and transmitter in communication with the microphone to transmit the wireless signal carrying the audio information to the receiver of the camera when the remote unit is not physically received by the docking station, andan electrical contact adapted to mate with the contact of the docking station when the remote unit is physically received, enabling the camera to receive the hardwired signal carrying the audio information.

Abstract
Remotely operable electronic apparatus are applied to distance measurement and picture/sound recording wherein, for example, a remote unit may be equipped with a microphone and an active range finder coupled to an auto-focussing capability. In one embodiment a camera is adapted to transmit a signal to the remote unit which returns a signal enabling the camera to accurately calculate distance and adjust focus in accordance with time-of-flight. The transponder preferably forms part of a wireless microphone, with the signal transmitted by the camera being preferably acoustical in nature. The acoustical signal transmitted by the camera is preferably modulated onto a return RF signal, enabling at least a portion of the audio circuitry associated with voice modulation to be used for the purpose of modulating the ranging signal, thereby realizing a very efficient and economical approach to remote sound detection and active ranging finding.
