Inventor: OLIVER STEVEN R
IPC: E03C1/05
Filed: 1999-11-19
Abstract: An electronic faucet sensor assembly includes a base having a pair of openings facing in a generally downward direction when the assembly is mounted in an electronically operated faucet. There is an infrared transmitter positioned in one of the openings and an infrared receiver positioned in the other opening. There is a lens mounted to the base and covering the transmitter and a second lens mounted to the base and covering the receiver. Electrical lead wires are attached to the transmitter and to the receiver and the lead wires extend through a channel located in the base. There is a strain relief at one end of the channel and there is a rib to isolate the leads extending between the strain relief and the transmitter and receiver so as to prevent electrical contact therebetween. The channel is filled with a potting compound to provide a watertight environment for the electrical components.

Patent CA-2301435-A1 (CA)
Title: Method for reducing congestion in packet-switched networks
Inventor: BELLOVIN STEVEN MICHAEL
IPC: H04L12/56
Filed: 2000-03-14
Abstract: The present invention permits a network service provider to detect an operational condition - such as congestion - in a packet-switched network and to alleviate such congestion by providing customer incentives to avoid use of the network. The detection mechanism triggers an incentive such as the modification of the user's access charges and the customer can be immediately notified of either the occurrence of the congestion or of information regarding the incentive. Usage of the network during congested periods can be deterred by imposing additional access charges during such periods - similarly, customers can be given a discount to encourage usage during periods of low congestion. An incentive schedule can be tailored to dynamically change the usage patterns of the customers of the network to accommodate the operational conditions in the network. The present invention has application in the Internet, where a detection/notification mechanism, for example, can be implemented in a network node such as a muter or in a network endpoint such as a client machine or a proxy or mail server.

Patent CA-2307684-A1 (CA)
Inventor: POPESCU PETRE
IPC: H03F3/72
Filed: 2000-05-05
Abstract: The invention relates to a driver circuitry suitable for controlling an operation of a laser or an optical modulator and providing extended dynamic range of the output power and enhanced quality of the output signal. It comprises a power control unit, a pre-driver stage and an output stage. The pre-driver stage and the output stage include differential amplifiers, the output stage amplifier preferably having a cascode configuration. The pre-driver stage provides a preliminary amplification of an input signal which is received and further amplified by the output stage. The power control unit operates in response to a reference signal, e.g. variable DC voltage or a feedback signal, and generates two control signals which control operating points of the pre-driver and the output stage in such a manner that higher output power of the driver corresponds to the higher output signal from the pre-driver stage. Conveniently, both the pre-driver stage and the output stage may be controlled by the same control signal. Depending on the product requirements, the driver circuit can be monolithically integrated with a device to be driven by the circuit.

Abstract: An interbody osteogenic fusion device (10) is provided that includes opposite end pieces (11, 12) with an integral central element (13). The end pieces (11, 12) are sized to maintain the height of an intervertebral disc space (S). The central element (13) has a much smaller diameter (D2) so that the osteogenic fusion device (10) forms an annular pocket (24) around the central element (13). An osteogenic material (30) is disposed within the annular pocket (24) between the opposite end pieces (11, 12). In one embodiment, the osteogenic material (30) constitutes a coIlagen sheet (30) soaked in a solution containing a bone morphogenetic protein (BMP). The osteogenic fusion device (10) is configured so that the osteogenic material (30) is in direct contact with the adjacent vertebral bone (V1, V2). In addition to the enhanced area of contact between the vertebral bone (V1, V2) and the fusion material (30), the inventive osteogenic fusion device (10) reduces stress-shielding and minimizes the radiopacity of the implant so that growth of the fusion mass can be continuously assessed. In yet another embodiment, the osteogenic fusion device (10) includes at least one end piece (12) with a truncated surface (21). The osteogenic fusion devices of the present invention may be combined with other fusion devices to form an implant system. The implant system (140) includes at least one load bearing member (110) having a truncated surface (116) configured to nest within another load bearing member, preferably the load bearing, osteogenic fusion device (10) of the present invention. The invention also provides implant systems (210) comprising adjacent load bearing members (211, 212) connected to one another to resist lateral separation. Methods of promoting fusion bone growth in the space (S) between adjacent vertebrae (V1, V2) utilizing devices and systems of the invention are also described.

Patent CA-2327812-A1 (CA)
Inventor: OTTAVIANI ANGELO
IPC: H01M8/06
Filed: 1999-04-23
Abstract: The invention describes a method for the direct connection of fuel cells to electrolyzers (2) of electro--chemical plants producing hydrogen as a by-product.  The by-product hydrogen is fed to the fuel cells and the electric energy thereby produced is transferred to the electrolyzers (2) - rectifiers (3), with the consequent saving of the overall energy consumption. The direct coupling avoids the need for DC/AC converters or volt-age adjusters and may be effected either in series or in parallel. In the latter case the fuel cells are assembled in modules, the number and voltage of which is regu-lated by means of interrupters (9, 10, 11) activated by a computerised control and supervision system. As an alternative, the voltage of the modules may be varied by varying the pressure of the air fed to the fuel cells.

Abstract: The invention relates to a method, device and receptacle for heating pre- prepared meals (4). Said meals can be accommodated in open or closed receptacles (11) and can be heated by means of induction heating coils. In t he catering industry, pre-prepared meals are normally heated using known circulating air ovens, whereby a greater power usage and relatively long heating times are disadvantageous especially during mobile use of these oven s. For inductively heating such pre-prepared meals, it is necessary to use corresponding special kitchenware suited therefor. The aim of the invention is to heat meals in a highly effective manner and with a good quality while usi ng less time and energy. To this end, the invention provides that the meals accommodated in the receptacles (11) are heated in closed compartments using  inductive heating coils and hot steam such that the heating time and the quality of such regenerated, pre-prepared meals can be decreased and improve d respectively.
