摘要:
An optical fiber (31) comprising an optical fiber main body and a coat formed therearound and made from a polyimide resin obtained by using as an acid component a tetracarboxylic dianhydride having at least two benzene rings fused or bound directly or via an oxygen atom has excellent resistance to high temperature and high humidity and adhesiveness to the optical fiber main body, and useful in a sensing part (41) in a fiber-optic sensing system comprising at least one sensing part (41) and signal transmitting paths.
摘要:
A system and method for load sharing processing operations between a vehicle mounted station (105) and a stationary base station (25) having a large capacity host computer (18) is described. The vehicle mounted station (105) has detectors for determining operating conditions of a vehicle and controllers (3,4,501) for varying the operating conditions. The controllers (3,4,501) are connected to a transmitter-receiver (5) which is arranged to communicate over a path (10) with a transmitter-receiver (11) of the base station (25). The base station (25) has a host computer (18) having a large memory capacity. At predetermined intervals, for example, distance of travel or at engine stop, the vehicle transmitter (5) transmits operating conditions to the base receiver (11) for data processing and the base transmitter (11) then transmits processed data back to the receiver vehicle (5), whereupon the controllers (3, 4, 501) modify the vehicle operating conditons. The vehicle operating conditions may be an indication of life expectancy of fuel injectors or sensors, updating data processing maps. The presence of abnormal operating conditions may be detected by the vehicle mounted station (105), evaluated by the base station (25) and an emergency warning indication provided back to the vehicle mounted station (105), or if the abnormal condition is not of an emergency nature then counter measures are transmitted from the base station (25) to the vehicle mounted station (105).
摘要:
In a circuit (1, 6, 12, 13, 21) for driving a liquid crystal display element, during a latter half part of an indication renewal period a common electrode is supplied with lower maximum and higher minimum voltages than the maximum and minimum voltages supplied during a first half part of the indication renewal period, in order to enhance response speed of the liquid crystal display element (5).
摘要:
A vehicle trip computer (1-11) for detecting the distance traveled by a vehicle and the amount of fuel remaining in the fuel tank and computing and displaying the capable travel distance of the vehicle through the desired computational operations in accordance with the detected data. During the initial period following the connection of the trip computer to the power source, the capable travel distance of the vehicle is computed by using a predetermined initial gas mileage in place of the computed gas mileage. Also, the trip computer does not replace the initial gas mileage with the computed actual gas mileage until the distance traveled by the vehicle exceeds a predetermined distance.
