Patent CA-2268162-A1 (CA)
Title: Idle control for internal combustion engine
Inventor: MCGINNITY FRANCIS A
IPC: F02M51/00
Filed: 1997-10-17
Abstract: A method of controlling fuel injection in an internal combustion engine including a crankshaft (58), a fuel injector (126) and a control unit (154) for outputting a signal causing a fuel injection event, with a minimum time delay between the output of the signal and initiation of the fuel injection event, the method comprising the steps of sensing the crankshaft (58) position (150), outputting the crankshaft position signal and providing an additional time delay between the output of the signal and the initiation of the fuel injection event so that the signal must be put-out at an earlier crankshaft position than would be necessary without the additional time delay, whereby changing the crankshaft speed has a greater effect upon the difference between the desired crankshaft position of the fuel injection event and the actual crankshaft position of the fuel injection event.

Patent CA-2276415-A1 (CA)
Inventor: KORN PETER A
IPC: G06F9/445
Filed: 1999-06-25
Abstract: A program loading arrangement is used in connection with a virtual machine for loading programs for processing in the virtual machine. The program loading arrangement includes a program/class loader and a dependency list. The dependency list identifies, for each program for which one or more classes are to be instantiated in the virtual machine for use during processing of the respective program, the class or classes that are to be so instanitated.  In response to a request to load a program for processing in the virtual machine, the program/class loader initiates loading of the program. In addition, the program/class loader determines from the dependency list whether any classes are to be instantiated for use during processing of the program being loaded and, if so, instantiates the respective classes. The information in the dependency list as to which class or classes are to be instantiated in the virtual machine when the respective programs are loaded can be provided by an operator, thereby to permit the operator to enable classes to be instantiated in the virtual machine which might not otherwise be instantiated for use during processing of the program.

Title: Technique for video communications using a coding-matched filter arrangement
Inventor: MATTHEWS KIM NIGEL
IPC: H04N7/50
Filed: 1999-07-02
Abstract: In a system for communicating an image, an image compression scheme is employed to encode the image to reduce the required bandwidth for transmitting same. For example, this compression scheme includes performing, on the image, a discrete cosine transform (DCT), followed by quantization. To reduce the effects of coding artifacts occasioned by the compression scheme, in accordance with the invention, a filter arrangement which is matched to the coding of the image may be utilized to process a received image. The filter arrangement is designed to truncate each non-zero frequency component in the received image whose amplitude is lower than a certain threshold, which is a function of the quantization step size used.
