Title: Clock recovery method and apparatus in a diversity receiver
Inventor: KAZECKI HENRY L
IPC: H04B7/26
Filed: 1993-02-26
Abstract: A diversity receiver (200) recovers clock information from different versions (301, 302) of a transmitted signal (106). The diversity receiver (200) receives the different versions (301, 302), converts the versions (301, 302) into samples (307, 317) via a common sampling clock (309). The receiver (200) then correlates the samples (307, 317) with like synchronization patterns and uses clock information from the received version (307 or 317) which gives the greatest correlation output signal (504, 506) for data detection in one of two detectors (323, 326). The choice of detectors (323, 326) is determined by the diversity receiver (200) by counting the total number of bit-differences output by detectors (323, 326) over a predetermined time period and comparing the total bit-differences with a number represented by a threshold signal (330). <IMAGE>

Title: Hydraulically-actuated fuel injector with idle stability port
Inventor: BEATTY DAVID J
IPC: F02M45/00
Filed: 1997-08-27
Abstract: A hydraulically-actuated fuel injector includes an injector body having a nozzle chamber 28 that opens to a nozzle outlet 29, a plunger bore 25, and an idle stability spill port 61 that open to the plunger bore and is blocked by the plunger 52 when in its retracted position. During delivery of fuel in the idle range, an annular groove 54 in the plunger becomes aligned with the port 61 whereby some fuel pressurized by the plunger spills through passages (56, Fig.3) and the groove 54, the remainder passing through the outlet 29. To this end the idle stability port has a relatively restricted flow area about equal to that of the nozzle outlet 29. A larger prime spill port 60 providing a relatively unrestricted flow area may be provided so that pre and main injections occur. Fuel flow off through the port 61 during idling conditions results in reduced variation in the injected quantity. Such variations normally arise due to fluctuations in rail pressure and/or plunger motion resulting from erratic operation of the poppet valve member 80 controlling the hydraulic actuation of the intensifier piston 50 driving the plunger 52.

Patent GB-2336455-A (GB)
Title: Detecting device and alarm system
Inventor: PAYNE ROGER DENNIS
IPC: G08B17/00
Filed: 1998-04-16
Abstract: An alarm system has detecting devices (manual call or sensor) and alarm devices connected in parallel across the same supply lines. A control unit supplies a first voltage to operate the detecting devices and a second higher voltage to operate the alarm devices. When e.g. a fire is detected, signalling means, in the detecting device, produce a change of state signal which causes impedance switching means to switch from a high to a low impedance state. This causes a current drain across the supply lines which is recognised by the control unit as the fire detection signal, which then applies the second voltage to the lines. Voltage responsive means respond to the second voltage to cause the Impedance switching means to switch to the high line impedance state. The current drain is thereby reduced to conserve battery power. This avoids large current drains when several detecting devices respond to the fire (e.g. when smoke detectors are triggered by spreading smoke). Additional voltage responsive means cause the impedance switching means to switch to a high impedance state, whenever the line voltage falls below a predetermined level below the first voltage. Circuitry is also described for maintaining the current drain on the supply lines substantially constant, for latching an alarm state, for delaying operation of the impedance switching means to enable the voltage on the supply lines to be switched rapidly between different levels without causing the impedance switching means to be in its low impedance state, and for operating on different polarities.
