Patent CA-2379621-A1 (CA)
Title: Apparatus and method for receiving bs digital broadcast
Inventor: HORII AKIHIRO
IPC: H04L27/22
Filed: 2001-05-17
Abstract: An improved apparatus for receiving BS digital broadcast is disclosed.  The apparatus for receiving BS digital broadcast of the present invention has first to third filters and a selective complex calculator circuit.   Each of the first to third filters 18 to 20 identifies the modulation technique applied to the received signal, by the modulation identification signals A0, Al received from a timing generator circuit 25, and filters a phase error signal PED  according to the identified modulation technique. The selective complex calculator circuit 21 shifts the phase of a signal point indicated by an I  signal ADI1 and a Q signal ADQ1 absolute-phased by an absolute-phasing section 14, by a phase corresponding to the phase error signal filtered by the first to third filters 18 to 20. At this moment, the selective complex calculator circuit 21 selects the phase error signal corresponding to the modulation technique identified from the modulation identification signals A0, Al received from the timing generator circuit 25. Consequently, in the burst receiving, it is possible to reduce the effect on the error rate because of the signal noise of the ODU to a degree equal to that in the continuous receiving.

Patent CA-2381191-A1 (CA)
Inventor: YARBROUGH GRAHAM G
IPC: G06F9/46
Filed: 2001-06-01
Abstract: The system comprises a first processor, a second processor and non-volatile memory. The non-volatile memory stores messages being transferred between the first and second processors. The non-volatile memory is resettably and logically decoupled from first and second processors to preserve the state of the first and second processors and the messages in the event of a loss of communication or a processor reset. The non-volatile memory increases the rate of message transfer by transferring blocks of messages between the non-volatile memory and the second processor. The non-volatile memory includes status and control registers to store the state of messages being transferred, message queues, and first and second processors. The system may also include a local power source to provide power to the non-volatile memory.

Title: Lumbar drainage catheter
Inventor: GRIFFIN MARK
IPC: A61M27/00
Filed: 2000-08-24
Abstract: This is a catheter assembly designed for accessing the cerebrospinal fluid circulation system and draining fluid therefrom. The polymeric thin-walled catheter has a soft, flexible distal region for minimizing trauma to tissue and angularly accessing the subarachnoid space in the cerebrospinal fluid pathway with an optional guidewire. A stiffer proximal region, which may optionally contain a reinforcing woven braid or coil ensures that the cathet er does not kink or compress during use in the tough membranes around the spina l column. One or more apertures in the catheter wall for draining fluid proximally through the catheter central lumen allows for transport of fluid through the catheter at therapeutic flow rates and pressures. A soft polymer ic plug that may be disposed in the distal end of the catheter assembly ensure minimal trauma to tissue upon entry. The entire catheter may be coated with hydrophilic coating to facilitate movement through an optional Touhy needle and tissue, and may be radio-opaque for greater visibility under fluoroscopy .

Patent CA-2393337-A1 (CA)
Inventor: KRAJEWSKI DAVID A
IPC: F04B49/06
Filed: 2000-12-15
Abstract: A pump used to infuse a fluid into a patient is controlled in accordance with an algorithm that enables a microprocessor (17) to monitor and adjust each pump cycle to compensate for a differential pressure between the pump's inlet and outlet. The algorithm defines a fluid delivery protocol that is applied in controlling the operation of the pump to achieve a desired rate, volume, and timing of the fluid infusion. Fluid is delivered by the pump when a plunger (42) compresses an elastomeric membrane (29) overlying a fluid chamber (30). Due to the small volume of the chamber, an incremental change in the plunger position before the delivery stroke produces a significant change in the delivery pressure. At the beginning of a pump cycle, the microprocessor determines the differential pressure between the inlet and outlet of the pump, and adjusts the plunger position before the delivery stroke to compensate for the differential pressure. A retraction of the plunger from the home position decreases the delivery pressure of the fluid, and an advancement of the plunger increases it. After the position of the plunger is adjusted to compensate for the differential pressure, the pump cycle proceeds. Following the plunger stroke, the outlet pressure is used to determine the actual volume of fluid delivered. The duration of the plunger stroke in the next pump cycle is adjusted to compensate for any volume delivery error produced by the differential pressure compensation.

Abstract: An appliance having a driving mechanism is provided, the appliance (10) comprising two rotatable portions (32, 34) which are rotatable by the driving mechanism (50) about an axis (40). The driving mechanism (50) comprises a gearbox (60) having an input gear (116), two output gears (240, 304) and a locking mechanism (250, 252, 318) movable between a first position and a second position. The arrangement is such that, when the locking mechanism (250, 252, 318) is in the first position and the input gear (116) is driven, both output gears (240, 304) rotate in the same direction and, when the locking mechanism (250, 252, 318) is in the second position and the input gear (116) is driven, the output gears (240, 304) rotate in opposite directions.  The arrangement of the axis (40) is horizontal or substantially horizontal.  The invention is particularly suitable for use in a front-loading washing machine (10) having a drum (30) comprising two rotatable portions (32, 34).  The driving mechanism (50) can be used to selectively cause rotation of the rotatable portions (32, 34) either in the same direction or in opposite directions.

Title: A device for monitoring fluid flow in a pump outlet
Inventor: SVENSSON STEFAN
IPC: G01F1/28
Filed: 2002-12-13
Abstract: The invention concerns a detecting and monitoring device for the liquid flow in a pump outlet.   A body (1) of permanent magnetic material is arranged to be able to move freely back and forth in the liquid flow in the pump outlet (3), the position of the body being decided by the intensity of the flow. A tongue element (4), which is located in a room separated from the pump outlet (3) by a wall, is influenced by the magnetic field from the body (1) and can thereby detect the position of the body and consequently the intensity of the flow. This knowledge is used to stop the energy supply of the pump motor when the intensity of the flow reaches a certain minimum value.

Title: Vehicle obstacle warning radar
Inventor: WALTON ERIC K
IPC: G01S13/931
Filed: 2003-01-15
Abstract: The present invention is a radar system for detecting the presence of obstacles. The radar system includes at least one transmitting antenna and at least one receiving antenna. The transmitting antenna receives an input signal and transmits an electromagnetic wave. The electromagnetic wave reflects off an obstacle back to the receiving antenna. The receiving antenna captures the refilected electromagnetic wave and produces an output signal. The output signal is then combined with the input signal in a quadrature mixer. The resulting in-phase (I) and quadrature (Q) signals may be further processed and then transmitted to a processing system. The processing system uses a suitable algorithm, e.g., a back projection algorithm, to estimate the type and location of obstacles that reflected the electromagnetic wave. In an exemplary embodiment, the algorithm is adapted to discriminate between different sizes and locations of obstacles in order to determine if there is a hazard. Based on this information, the processing system then communicates with a visual and/or audible warning system in order to alert the driver about the obstacle if it has been determined to be a hazard.
