Title: Method and apparatus for heating a catalytic converter to reduce emissions
Inventor: APPLEBY ANTHONY JOHN
IPC: F02M25/12
Filed: 1995-10-06
Abstract: A mixture of hydrogen and air is introduced onto the face of the catalytic monolith of a catalytic converter in the exhaust line of a cold internal combustion engine. The hydrogen spontaneously combusts, thereby pre-heating the catalytic converter. Pre-heating the catalytic converter significantly improves the effectiveness of the catalytic converter in eliminating undesirable emissions of the internal combustion engine. The hydrogen is preferably produced on-board the vehicle using the system. The hydrogen source may also be coupled to the internal combustion engine to be burned by the engine during startup in the absence of gasoline to minimize the production of unacceptable emissions while the catalyst is brought up to light-off temperature.

Patent CA-2216077-A1 (CA)
Title: Scene change detector for digital video
Inventor: LIU VINCENT
IPC: H04N7/32
Filed: 1997-09-19
Abstract: In a method for detecting a scene change between a prior video picture and a current video picture of a sequence of pictures, an average luminance value is determined for a block pair of the prior and current video pictures. Preferably, the blocks of the block pair are located, respectively, in the same relative position in the prior and current pictures. An incremental visual sensation value is determined using a difference between the average luminance values. If the incremental visual sensation value exceeds a block contrast threshold level, a scene change is indicated. In particular, if the minimum of the average luminance values of the current and prior picture blocks exceeds a dark scene threshold, the incremental visual sensation value is determined using the ratio of (a) the absolute value of the difference between the average luminance values, and (b) the minimum of the average luminance values of the current and prior picture blocks. Otherwise, the incremental visual sensation value is determined using the ratio of (a) the absolute value of the difference, and (b) the dark scene threshold. The method may be optimized by adjusting the block size based on the relative amount of motion and the current picture type.

Title: Method and apparatus for testing multi-port memory
Inventor: NADEAU-DOSTIE BENOIT
IPC: G11C8/16
Filed: 1997-10-31
Abstract: A method of and apparatus for testing multi-port memory performs a shadow read to an adjacent memory cell concurrent with a write operation associated with typical read-write testing. In the presence of a bit wire short or a word wire short, the concurrent read of an adjacent memory cell will cause the value of that cell to be corrupted. The corrupted value is then found by the read-write testing. Consequently, the testing takes no longer than read-write testing. In addition, the testing scheme can be modified for memory with read only ports. An embodiment of the apparatus employs an exclusive OR gate on the least significant bit of the test row address line to generate the shadow read address.
Patent CA-2220285-A1 (CA)

Title: Thermostatically controlled mixing valve
Inventor: KNAPP ALFONS
IPC: G05D23/12
Filed: 1997-03-26
Abstract: A retaining device for frictionally retaining two mobile parts of a thermostatically controlled mixing valve. The first part (2) of the mixing valve contains a cavity having a side wall (40), a top wall (41) and a bottom wall (42). An O-ring type packing washer (9) is disposed in the cavity and frictionally grips a surface of the second mobile part (13). The axial distance between top wall (41) and bottom wall (42) of the cavity is less than the cross-sectional diameter in the axial direction of the ring-shaped packing washer (9). The packing washer (9) is thus compressed axially and establishes a frictional hold between the top wall (41) and bottom wall (42) of the cavity and the axially extending surface of the second mobile part (13). The diameter of the cavity is greater than the diameter of the compressed ring-shaped packing washer (9) thereby forming a ring-shaped space or chamber between the washer (9) and the side wall (40). This ring-shaped space communicates with a water holding area of the mixing valve through a groove (43) in the bottom wall (42) of the cavity.
