TL;DR: In this paper, a lidar detector is coupled to the time varying threshold generator and to the photodiode to provide signals indicating presence or absence of an object in the first and second fields of view.

TL;DR: A turbine alternator comprising a central clear optical path through which certain objects or optics may pass unimpeded is presented in this paper, where a means for internal safe arming of the munition in which the turbine alternators is contained.

TL;DR: In this paper, an apparatus consisting of a signal input and a sampler and an analog-to-digital (A/D) converter coupled to the signal input is presented.

Abstract: A system (4) for use in an automobile (2) for the detection of objects comprising: a light source (6); a plurality of spaced transmitter ports (10, 12) for respectively transmitting light to a plurality of fields of illumination (18, 20); an optical fiber coupling the light source to the transmitter ports; a plurality of receiver ports (10, 12) embracing respectively a plurality of fields of reception (34, 36) each having an area of overlap (38, 40, 42, 44) with each of the plurality of fields of illumination so as to receive light transmitted from one of the transmitter ports and reflected by an object present in an area of overlap; a receiver (22) for receiving light and for producing a signal representative thereof; an optical fiber (24) coupling the receiver ports to the receiver; and processing means (52) for sequentially activating each of the transmitter ports with each of the receiver ports, and for processing the signal produced by the receiver in response to each activation to detect the presence of an object in each of the areas of overlap.

TL;DR: In this article, a modulation circuit is designed to provide an LED with a more analog type signal, which in turn causes the LED to emit a signal that is peaked rather than a constant square wave providing a better conversion frequency to the fundamental frequency.
