摘要： Optical telecommunication systems using phase-compensation interferometry wherein receiver units have N interferometer configurations each with a unique path length difference that is identical to a path length difference in one of N interferometer configurations at the corresponding transmitter units. The transmitter and receiver units separately and individually use N+1 arms, one of which serves as a reference common to the other N arms that along with the common reference arm form the N interferometer configurations of the transmitter and receiver units. N phase modulators, one in each of the N paths of the transmission units, are used to apply a separate and individual telecommunication signal (payload) to the portion of the light in that path. These N separate payloads may be of the same or different protocols. These N separate payloads may have the same or different bit rate/second. These N separate payloads may be digital or analog. These N payloads may be individually and separately dropped out or inserted at a drop/insert site. These N separate payloads may be used to increase the capacity of a transmission path by a factor of up to N. These N separate payloads may be used to employ lower bit rate/second electrons to produce a higher bit rate/second payload where the increased in bit rate/second is a factor of up to N.

摘要： A liquid chromatographic method and apparatus is disclosed which employs an improved pump not requiring driven pistons or sliding seals. The pump comprises at least one length of tubing forming a chamber disposed between first and second check valves, controllable heating means to periodically heat liquid in said chamber effective to pump relatively low volumes of liquid from the chamber at relatively high pressures, means for measuring the pressure developed by the pump, and control means to increase and decrease the amount of heat imparted to the liquid to maintain the pump operation at a controlled pressure setpoint.

摘要： A highly sensitive microbend horizontal fiber-optic accelerometer has been conceived, particularly useful in seismological research where minute accelerations must be detected. The device uses a cantilever beam and the compliance of an optical fiber mounted between deforming teeth to act as the springs in the accelerometer's spring-mass system. Acceleration is detected by sensing the changes in the intensity of light propagating through the deformed fiber due to the motion of the mass relative to the case. Accelerations as small as 5 .mu.g at 1 Hz can be detected with a dynamic range of 100 dB.

摘要： A shield which keeps light from reaching a subject's eyes. The shield is permeable, but capable of blocking the transmission of light; and it has an adhesive for removably securing it to the user's face. An accessory usable with the mask to extend its useful life by replacing the shield securing adhesive is also disclosed.
