Abstract: An integrated transmitting-receiving circuit (transceiver) designed as two complementary types for an optical duplex system with two light waves with different operating wavelengths to be transmitted in opposite directions via an optical fibre has a wavelength-independent optical switch designed as a Y structure formed of waveguide paths. The first path of the switch is designed as a connecting waveguide between the optical fibre and the two other paths, the second path leads to the transmission laser designed according to the complementary type for the corresponding operating wavelength, and the third path leads to a photodetector system with two photodetector sections optically connected in series, designed each for one of the two operating wavelengths and electrically independent of one another. The photodetector section designed for the shorter operating wavelength is arranged between the switch and the photodetector section designed for the longer operating wavelength.

Title: Electrohydraulic control system for automatic control of earth mover shovel
Inventor: SHULL ANDREW G
IPC: E02F3/43
Filed: 1998-01-05
Abstract: The system controls the shovel (16) of an earth moving machine, which is operated controllably by a hydraulic lifting cylinder (14) and a tilting cylinder (15). The control system includes pressure sensing facilities, for producing pressure signals in response to the hydraulic pressures, which are each associated with the lifting and tilting cylinders. Position sensing facilities are provided for producing position signals, which represent the respective extensions of the lifting and tilting cylinders. Command signal production facilities receive the position and the pressure signals, and from these compute the responding correlative force vector angle, which represents the combined forces, which react at a reference point on the shovel. Cylinder speed command signals are produced as a result, which correspond to the difference between the force vector angle and the desired angle.
