Abstract: In one embodiment, a lidar system includes a light source configured to emit local-oscillator (LO) light and pulses of light, the emitted pulses of light including a first emitted pulse of light, where an optical frequency of the first emitted pulse of light is offset from an optical frequency of the LO light by a first frequency offset. The lidar system further includes a receiver configured to detect the LO light and a first received pulse of light, the first received pulse of light including light from the first emitted pulse of light scattered by a target located a distance from the lidar system. The receiver includes a detector, where: the LO light and the first received pulse of light are coherently mixed together at the detector, and the detector is configured to produce a photocurrent signal corresponding to the coherent mixing.

Abstract: A system for placing data in a format for acceptance by a general purpose communications printer, the data originally being in a format for providing a television display to news wire service subscribers, and being originally in a format composed of signals representing a succession of characters. The data is temporarily stored and then read out in segments each containing signals representing the number of characters per line in the printer output, printer control signals are inserted between segments, and the resulting composite signal is then conducted to the printer locations, where it is placed in a form which can be applied to a printer.
