Title: Intra-vehicular local area network and method of routing messages along it
Inventor: LUITJE WILLIAM V
IPC: G06F17/30
Filed: 1995-03-30
Abstract: Microcontrollers (10), e.g. those located within a vehicle or factory, are connected over a local area network (LAN) (25). The microcontrollers broadcast messages on the LAN tagged with an identifier (ID) which identifies the contents of the message, rather than a destination address. Microcontrollers on the network are provided with read only memory (ROM) (5) containing a table of message IDs and accompanying data, wherein the table address of each message ID was initially determined by applying a hash function to the ID. Upon receipt of a message, a microcontroller (10) applies the hash function to the message ID (Step 32). Using the result as a pointer into the table (Step 33), the microcontroller compares the message ID stored in that pointer location with the received message ID. If they are equal, the microcontroller performs a predetermined function (Step 34). If the message IDs are not equal, the message is ignored (Step 35).

Title: Method and system for camera with motion detection
Inventor: DICKINSON ALEXANDER GEORGE
IPC: H04N5/232
Filed: 1995-11-09
Abstract: A motion detection camera system which may be used as a security camera includes an active pixel imaging system operable in a video and differential mode connected to a mode activation circuit that controls the imaging system mode. In the video mode, the imaging system generates an output signal containing informationof a viewed area on a frame by frame manner. In the differential mode, the imaging system generates a differential output signal containing information consisting of the differences in the viewed area between adjacent detected frames. Normally, the imaging system camera is operated in the differential mode. If no motion occurs in the viewed area, the corresponding differential output signal representing the interframe differences will have a constant signal level. Upon detecting that the differential output signal deviates by greater than a threshold level indicating motion in the viewed area, the mode activation circuit causes the imaging system to operate in its video mode. The corresponding generated video output signal of the imaging system is then provided to monitoring equipment, such as a video cassette recorder for recording of the motion in the viewed area.

Patent CA-2168807-A1 (CA)
Title: Gas flare
Inventor: JONES WENDYLE
IPC: F23D14/24
Filed: 1996-02-05
Abstract: A gas flare is described which includes a vent stack for combustion air having a first end and a second end.  A gaseous fuel cyclone chamber surrounds the vent stack.  The cyclone chamber has an interior wall conterminous with the vent stack and an exterior wall spaced from the vent stack.  The cyclone chamber has a narrowing defining an access opening adjacent the first end of the vent stack.  A gaseous fuel injection ring surrounds the first end of the vent stack with fuel nozzles extending into the access opening of the cyclone chamber. Gaseous fuel is fed into the cyclone chamber for thorough mixing prior to combustion. An igniter is positioned above the first end of the vent stack.   Gaseous fuel flowing under pressure from the cyclone chamber creates a venturi effect drawing air up the vent stack to form a mixture of air and gaseous fuel which is ignited by the igniter.  A combustion air passage communicates with the second end of the vent stack. The combustion air passage follows a circuitous route passing along the exterior wall of the cyclone chamber adjacent the first end of the vent stack such that cool combustion air passing through the combustion air passage draws heat from cyclone chamber to reduce heat build up adjacent the first end of the vent stack.

Patent CA-2174358-A1 (CA)
Inventor: REID SCOTT EDWARD
IPC: A24F19/14
Filed: 1996-04-17
Abstract: A combination cigarette suffocater and ashtray made up of two pieces. The ashtray, or ash retainer, is designed in a way to allow the suffocater (hereby referred to as the snuffer) to sit squarely and evenly in its midst. The cigarette is extinguished by depositing its lit ember into one of the cavities bored through the snuffer. Once all of the cavities are filled, simply lift the snuffer slightly higher than the length of the filters off the base. The extinguished cigarettes then drops through, rolling off the slant of the base into the lower-most part of the ashtray. The snuffer is then replaced to its original position. Its cigarette holders are structured in sharp angles, with openings no less than the width of a cigarette, to firmly hold its burning embers above previously entinguished cigarettes. This is the only omni-cut structure, to this inventor's knowledge, that impedes a burning cigarette from tipping over the exterior onto a probable ignitable surface. One can also structure the holders within the ash retainer, but this structure is more complex, and therefore more costly to manufacture.
