IPC: G06F1/10
Filed: 1991-07-10
Abstract: A circuit to provide single phase clock signals having controlled clock skew to multiple integrated circuit chips is described. A source of single phase clock signals is supplied to a clock signal distribution tree of each integrated circuit. Phase comparison of signals produced by each clock distribution circuit tree provides a control signal for controlling the delay of a clock signal applied to a respective clock distribution tree. A gating circuit is disclosed which produces, in response to each clock signal produced by the clock distribution trees, an accurately controlled LOAD ENABLE and OUTPUT ENABLE signal.

Abstract: A passive propellant management system for a spacecraft liquid propellant tank comprises several preferably V-shaped channels (2A,2B,2C,2D) which communicate liquid propellant from regions within the tank to an outlet port, which expels liquid propellant but not pressurant gas. A liquid/bubble chamber assembly (9) couples the channels (2A,2B,2C,2D) with the outlet port. The channels (2A,2B,2C,2D) comprise relatively open portions (11) and relatively closed portions (10). In the relatively open portions (11), liquid is retained in a gap (12) between open ends of the V channels (2) and the inner wall of the tank (1). In the relatively closed portions (10), a screen, mesh or perforated plate (14) covers the open end of the V channels (2A,2B,2C,2D), intermediate the V channels (2A,2B,2C,2D) and the inner wall of the tank. The placement of the relatively open and closed portions (11, 10, respectively) is intentionally preselected based upon mission requirements. Where pressurant gas ullage is expected to be present, e.g., during periods of high g, relatively open portions (11) are used. Where liquid propellant is expected to be present, e.g., during periods of relatively low g, relatively closed portions (10) are used. The liquid/bubble chamber assembly (9) comprises a liquid trap (27) and bubble trap (28), which operate synergistically with each other and with the channels (2A,2B,2C,2D) to provide optimum liquid flow during all phases of the spacecraft mission.

Abstract: A restoration system is provided for enhancing the reliability of a telecommunications network (200) such that particular traffic which is disrupted by, for example, a faulty link, (e.g. 103) may be quickly rerouted via an alternate route established "on the fly". In particular, each node (100-1 to 100-9) and link (101 to 111) forming the network is monitored, and in the event that such monitoring detects a faulty link or node then a central controller is notified. The controller is arranged to locate spare capacity and establish an alternate route, (e.g. 102, 106, 107, 104) in which the continuity of the alternate route is confirmed before the disrupted traffic is transferred thereto.
