Patent CA-2224755-A1 (CA)
Inventor: JAYARAMAN SUMANT
IPC: F02M7/24
Filed: 1997-12-12
Abstract: The present invention involves a carbureted fuel system for an internal combustion engine for small utility implements. The engine includes a crankcase with a cylinder bore. The crankcase rotatably supports a crank shaft having a flywheel and a magnet disposed on an outer periphery of the flywheel. The crankshaft is also connected to a reciprocating piston disposed in the cylinder bore. A cylinder head is attached to the crankcase over the cylinder bore, and a carburetor is disposed on the cylinder head. The carburetor is in communication with a fuel supply and an air inlet. The carburetor includes a mixing chamber in which the fuel and air are mixed together and then introduced into the manifold and eventually into the cylinder via a valve for combustion therein. In communication with the main passage of the carburetor is a secondary air inlet in which is disposed an air bleed device, such as a solenoid or PZT operated actuator, which is controlled by an electronic control unit. An induction coil is disposed adjacent the flywheel and is coupled to the electronic control unit so that the rotation of the flywheel generates a pulse on the induction coil that is processed by the electronic control unit. Based upon the information derived from the electrical pulses generated by the induction coil, the electronic control unit activates the air bleed device to enrich or enlean the air-to-fuel mixture fed into the cylinder for combustion. In this manner emissions associated with the operation of the engine may be reduced.

Patent CA-2227434-A1 (CA)
Title: Method and apparatus for strong affinity multiprocessor scheduling
Inventor: MERKEY JEFFREY V
IPC: G06F9/50
Filed: 1996-07-25
Abstract: A method and apparatus for scheduling threads on a multiprocessor utilize an unlocked local queue for each processor in the multiprocessor and a lockable global dispatch queue accessible by all processors. Threads are selected for movement from the unlocked local queue to the global dispatch queue only when the unlocked local queue contains too many threads that are waiting for a processor. Threads are selected to run on an available processor only after repeated checks to make certain no threads in the processor's unlocked local queue should be run first. As a result, threads assigned to a processor tend to stay with that processor unless the system load is severely unbalanced, thereby improving system performance by increasing cache hits and decreasing lock assertions.

Title: Automatic volume adjustment in a wireless handset
Inventor: HARDOUIN LARRY J
IPC: H04W48/04
Filed: 1998-03-18
Abstract: Determining in a wireless telecommunication switching system a base station on which a wireless handset is registered and using information concerning background noise at the location of the base station to automatically adjust the ringer and voice volumes for each call received by the wireless handset while registered on that base station. Further, the wireless telecommunication switching system automatically adjusts the voice volume when a call is handed off from one base station to another base station. Each base station may automatically determine the amount of background noise and transmits this information to the wireless telecommunication system controller which stores this information for future use. Also, each time a user of a wireless handset adjusts the volume of the handset, this information may be transmitted to the wireless communication switching system controller which stores the information as a preference for the user in the area served by that particular base station. In addition, the system administrator may determine the background noise for each base station and does so for different times of day. Finally, the system administrator may determine the noise level for the different areas of the building and as base stations are added to the wireless telecommunication system, they inherit the attributes of the area where they are placed.

Patent CA-2234493-A1 (CA)
Title: State machine architecture with multiplexed random access memory
Inventor: CARR LARRIE SIMON
IPC: G06F9/38
Filed: 1998-04-09
Abstract: A plurality of time-division multiplexed data streams which are merged into a single data stream containing a plurality of data words and which are characterized by state vectors, are concurrently processed.      The state vectors are stored in a read-write memory having a plurality of addressable memory locations. During an initial clock cycle, a pipeline receives an input data word from one of the data streams, an input state vector characterizing that data stream, and the memory location address of the input state vector. During one or more intermediate clock cycles, the pipeline processes the input data word and the input state vector to yield an output data word and an output state vector. During a final clock cycle, the pipeline transfers the output data word to an outgoing data stream, and transfers the output state vector into the aforementioned memory location address. A controller coupled to the memory and to the pipeline synchronizes operation thereof. A null cycle generator coupled to the pipeline and to the controller inserts null cycles into the concurrently processed data streams at regular time intervals and outputs a NULL signal to the controller during each null cycle. A multiplexer coupled between the controller and the memory multiplexes access to the memory between the controller/pipeline, and an alternate controller.     Read access to the memory by the controller or pipeline is inhibited while the NULL signal is output, and write access to the memory by the pipeline is inhibited while an OUTGOING NULL replica of the NULL signal is being output by the pipeline during the final clock cycle.      Accordingly, the alternate controller may gain read access to the memory while the NULL signal is output, and may gain write access to the memory while the OUTGOING NULL signal is output.

IPC: A01D75/00
Filed: 1998-09-15
Abstract: The threshing cylinder or rotor of a combine harvester is driven by a rotor hydraulic motor. A rotor pump, driven by an internal combustion engine supplies hydraulic fluid to the rotor hydraulic motor to drive the rotor. A variable speed traction drive propels the harvester over the surface of a field to harvest crops. A control system varies the ground speed of the harvester based upon the pressure of hydraulic fluid supplied to the rotor hydraulic motor to maintain a substantially constant crop material feed rate through the threshing cylinder or rotor. The control system can be an electronic system that measures the pressure of hydraulic fluid on the inlet side of the rotor hydraulic motor and varies the ground speed to keep the measured hydraulic fluid pressure substantially constant. A control system can also include a pressure control valve that varies the ground speed to maintain a constant rotor motor inlet hydraulic pressure.
