Patent CA-2299740-C (CA)
Inventor: CHING CHI CHENG
IPC: H05B37/02

Granted: 2004-05-18
Abstract: A lamp string controlling device includes a power supply circuit constituted by a transformer and a rectification circuit for converting an alternate current into a direct current. A harmonic oscillation circuit is connected between the transformer and the rectification circuit for eliminating noise and electromagnetic interference. A single chip based control circuit is connected between the power supply circuit and a driver circuit which drives a lamp string. The control circuit controls the lighting status of the lamp string between a full load condition and a non-full load condition in a variety of styles. A timing circuit having a time constant is coupled to the control circuit for switching the lamp string from a full load condition to the non-full load condition after a time period determined by the time constant thereof whereby overall power consumption of the lamp string may be lowered down and thus a small-sized transformer suffices for the operation of the lamp string.      Therefore a compact lamp string controlling device may be formed by combining the power supply circuit and the control circuit together. A manual switch and a remote control module may be coupled to the control circuit for manual and remote control.

Title: Sensor cell for an electrochemical fuel cell stack
Inventor: LAURITZEN MICHAEL V
IPC: H01M8/10
Filed: 1999-07-02
Granted: 2007-01-23
Abstract: An electrochemical fuel cell stack includes a plurality of fuel cells. At least one of the fuel cells is a sensor cell. The sensor cell has at least one structural dissimilarity with respect to the remaining fuel cells of the plurality. The structural dissimilarity may include, for example, a reduced sensor cell electrochemically active area, reduced electrocatalyst loading, modified anode or cathode flow field, different electrocatalyst composition, or a modified coolant flow field configuration. The sensor cell operates under substantially the same conditions as the remaining cells in the stack. However, in response to a change in a particular stack operating condition, an electrical or thermal response, preferably a voltage change, is induced in the sensor cell which is not simultaneously induced in the remaining fuel cells. Thus, the sensor cell can detect undesirable conditions and its response can be used to initiate corrective action. More than one sensor cell, specific to different types of conditions, may be employed in the stack. In the absence of undesirable conditions, the sensor cell can function as a power-producing fuel cell.

An endless loop conveyor belt (52) is received loosely over the endless loop drive chains, covering the chains but leaving slack in the belt . When the motor turns the drive sprocket assembly, advancing the drive chains and spacer bars, the weight of the bulk flow material holds the conveyor bel t tightly down, against the chains and bars, creating friction to prevent slippage between the chains and the belt, thereby allowing the chains to advance the belt, and the bulk flow material thereon.

Abstract: The present invention relates to multiprocessing systems in which signals o r processes are scheduled in order of their priority level. The invention is based on batch-wise acceptance and scheduling of job signals, and utilizes at least one delay queue (20) for temporarily storing job signals to the processing system before they are accepted for scheduling. The processing system further comprises circuitry (25) for batch - wise insertion of the temporarily stored job signals into the job scheduler (30) of the multiprocessing system. In this way, the utilization of the parallel processing units (45A-D) is increased and the number of changes between different priority levels in the multiprocessing system is minimized.

Abstract: A hypodermic syringe with a selectively retractable includes an elongate barrel having an open proximal end and a distal end that defines a receiver with an inwardly projecting shoulder. The syringe has a hollow elongate plunger with an open proximal end and a closed distal end. There is an elongate plug extending distally into the hollow plunger from the open proximal end forming an enclosed cavity within the plunger. The syringe has an elongate hub having a passageway therethrough, a distally extending stem, and a proximal flange with an engagement for engaging said barrel. The syringe has an elongate needle having a fluid path therethrough, a sharpened distal end and a proximal end. The needle is mounted in the passageway so that the sharpened distal end projects.  The syringe has an elongate spring disposed about the stem of the hub that is compressed between the flange and the inwardly projecting shoulder of the receiver to provide a bias.  There is a hollow sleeve sized to fit within the receiver over the elongate spring with a proximal sharpened end disposed in the groove of the flange. When a user applies a sufficient force, the hub is sufficiently moved distally in the receiver for the cutting edge of the sleeve to cut through the flange and the closed distal end of the plunger to expose the cavity for withdrawal of the needle into the syringe.
