Title: Occupant type and position detection system
Inventor: BRUCE MICHAEL P
IPC: G06T7/00
Filed: 1998-04-16
Abstract: A method and system (10) for detecting vehicle occupant type and position utilizes a single camera unit (12) positioned, for example at the driver or passenger side A-pillar, to generate image data of the front seating area of the vehicle. The present invention distinguishes between objects, forwardly or rearwardly facing child seats, and occupants, by periodically mapping the image taken of the interior of the vehicle into an image profile (104), and utilizing image profile matching with stored profile data (110) to determine the occupant or object type. The system and method of the present invention track occupant type and position in both parallel and perpendicular directions relative to a fixed structure such as the vehicle instrument panel to optimize both the efficiency and safety in controlling deployment of a occupant safety device, such as an air bag (28).
Patent CA-2286425-A1 (CA)
Inventor: YOAKUM JOHN H
IPC: H04Q3/00
Filed: 1999-10-18
Abstract: The common channel signaling (CCS) system of the public switched telecommunication network involves digital call routing information that is communicated between the switches of the network and signal transfer points (STPs) of the CCS system and among the STPs themselves. The CCS system causes the network switches and the trunks that connect them to be so interconnected as to complete a connection between a calling party and a called party. The STPs are kept as close as practicable to the network switches so as to minimize the length of the digital transmission links between them. This results in a proliferation of less-than-optimally utilized STPs. Therefore, the constituent parts of a STP  are geographically distributed over a wide geographical area with higher-capacity digital links between the constituent parts of the STP, in order to realize substantial transmission cost savings and to drastically reduce the number of individual STPs extant and thus reduce the complexity of the CCS communication between them.

Title: Electrically sequenced tractor
Inventor: MOORE N BRUCE
IPC: E21B4/18
Filed: 1999-12-17
Abstract: A downhole drilling tractor for moving within a borehole with predetermined speed, thrust and direction based on control signals from the surface and feedback signals from various sensors. The downhole drilling tractor of the invention comprises a tractor body, two packerfeet, two aft propulsion cylinders, and two forward propulsion cylinders. The body comprises aft and forward shafts and a central control assembly. The packerfeet and propulsion cylinders are slidably engaged with the tractor body. Drilling fluid can be delivered to the packerfeet to cause the packerfeet to grip onto the borehole wall. Drilling fluid can be delivered to the propulsion cylinders to selectively provide downhole or uphole hydraulic thrust to the tractor body. The tractor receives drilling fluid from a drill string extending to the surface. A system of spool valves in the control assembly controls the distribution of drilling fluid to the packerfeet and cylinders. The valve positions are controlled by motors. A programmable electronic logic component on the tractor receives the control signals from the surface and feedback signals from various sensors on the tool. The feedback signals may include pressure, position, and load signals. The logic component also generates and transmits command signals to the motors, to electronically sequence the valves. Advantageously, the logic component operates according to a control algorithm for intelligently sequencing the valves to control the speed, thrust, and direction of the tractor.
