Stereoscopic video system and method in which left and right images are displayed during alternate fields of a video picture frame. The equalization pulses occurring during the vertical blanking interval at the outset of each field are counted to identify the field. The field identification information is utilized to synchronize the presentation of the images to the proper eyes of a viewer. Flickering of the images seen by the viewer is reduced by limiting the intensity or brightness of the displayed images to which the eyes of the viewer are exposed.

Stereoscopic video system and method with field synchronization and

Method and apparatus utilizing constant current charging and discharging to determine the capacitance of a telephone cable or other circuit element. An output signal corresponding to the time required to increase the voltage from a first level to a second level and back to the first level corresponds to the capacitance of the element and, in the case of a cable, the length of the cable.

System and method for determining capacitance and cable length in the

A mobile radio extension unit for converting a conventional mobile transceiver having a transmitter and a receiver to use as a repeater or transponder for establishing a bidirectional communications link between a transceiver of limited range and a base station or other mobile transceivers in the network. In a mobile communications system network having a plurality of extension units, associated mobile radios, and limited range transceivers, each extension unit includes means for automatically inhibiting multiple transmissions by units within range of one another and for providing punch through priority communications from a limited range transceiver to the base station or other mobile transceivers via one selected extension unit when the receiver associated therewith is repeating a communication to the transceiver.
