Patent CA-2003636-A1 (CA)
IPC: B60G17/04
Filed: 1989-11-22
Abstract: An active vehicle suspension includes a strut (10) comprising a piston (12) working in a cylinder (11) and movable to compensate for unexpected road inputs to the suspension and for inputs generated by the driver, such as inertial forces introduced by braking or cornering. At times when the piston (12) is being moved by the road and driver inputs to compress the strut (10) excess hydraulic fluid is fed from the strut (10) to an accumulator (33) where it is temporarily stored at high pressure and later released back to the strut (10) when it is desired to increase the length of the strut. Thus some, and sometimes all, of the energy needed to extend the strut (10) can be supplied by the accumulator (33) rather than a pump (P). This saves energy. The piston (12) has unequal areas and a system of spool valves (32, 39) is provided to control the flow of fluid between the strut (10), accumulator (33), and pump (P).

Title: Error detecting device for electronic equipment
IPC: G06F11/32
Filed: 1990-03-09
Abstract: ABSTRACT OF THE DISCLOSURE   A device for detecting errors of a plurality of electric parts which are built in electronic equipment has error detecting circuits in the form of relays. The relays are interconnected one-to-one to various electric parts which are the subject of error detection, while display circuits are interconnected on-to-one to the relays. Output signals of the relays are fed to a reporting circuit without the intermediary of the display circuits. When an electric part is free from an error and only a display circuit associated therewith has failed, no error signal is fed to the reporting circuit. Only when any of the electric parts has really failed, on error signal is delivered to the reporting circuit to cause the latter to take an adequate measure such as the interruption of power supply.

Inventor: HELLWIG JOHN
IPC: G02B6/44
Filed: 1990-04-17
Abstract: An office panelling system is advantageously combined with fiber optic communication cable wherein the panels of the system are generally open in the center thereof and the vertical space of the panel is advantageously used for reducing the curvature of the cable between panels disposed at an angle.  The panels have a metal framework onto the sides of which cover members are secured such that the interior of the framework is generally open.  The framework includes a host of distributed passage ports therethrough for allowing communication cables and the like to pass through the framework where desired.  The fiber optic communication cable is strung through the frameworks of the panels and rounds corners between panels disposed at an angle by using both the vertical and horizontal planes of the framework to provide a curvature in the cable rounding the corner between angled panels much greater than the angle of curvature of the cable if the cable was confined to a single horizontal plane for rounding the same corner.  The rate of curvature of the cable is important, as in fiber optic cables light loss is encountered with any corner and the extent of the light loss increases as the radius of curvature becomes smaller.  It is the general practice that the rate of curvature should not be less than ten times the diameter of the cable.
