Patent CA-2513950-A1 (CA)
Title: Surgical stapling instrument incorporating an electroactive polymer actuated firing bar track through an articulation joint
Inventor: WALES KENNETH S
IPC: A61B17/072
Filed: 2005-07-27
Abstract: A surgical stapling instrument particularly suited to endoscopic use articulates an end effector (e.g., stapling and severing) that is actuated by a firing bar. An articulation mechanism in an elongate shaft incorporates electrically actuated polymer (EAP) actuators that laterally support the firing bar so that the firing bar is sufficiently constrained to avoid a blow-out, yet is guided without excessive friction and binding. Thereby, effective, consistent firing is accomplished without an undue increase in firing force required when the end effector is articulated.

Title: Initializing position and direction of mining vehicle
Inventor: MAEKELAE HANNU
IPC: G05D1/00
Filed: 2004-03-25
Abstract: The invention relates to a method of initializing the position and direction of a mining vehicle, and to a mining vehicle. An environmental model and route points (14) are stored in a control system of the vehicle (1). The environment of the vehicle is scanned, and scanned points are generated based on obstacles observed. The control system is arranged to determine coordinates of the scanned points by using the position of the route points (14) within a search range (15) and at least one direction. The coordinates calculated for the scanned points are compared with the environmental model. Such a route point (14) and direction are selected as initial values for the mining vehicle, by which the generated coordinates of the scanned points best match the environmental model.

Filed: 2004-04-21
Abstract: A conventional CMOS fabrication technique is used to integrate the formation of passive optical devices and active electro-optic devices with standard CMOS  electrical devices on a common SOI structure. The electrical devices and optical devices share the same surface SOI layer (a relatively thin, single crystal silicon layer), with various required semiconductor layers then formed over the SOI layer. In some instances, a set of process steps may be used to simultaneously form regions in both electrical and optical devices.

Filed: 2004-05-10
Abstract: The invention relates to a system for safeguarding dangerous substances, such as fuels, in tank reservoirs, comprising a tank reservoir and a feed unit, which is connected to the tank reservoir and inside of which substances that bind dangerous substances are located and can be transferred into the tank reservoir. The tank reservoir and feed unit are connected to one another in such a manner and the substances that bind dangerous substances are selected in such a way that, when transferring the substances, the dangerous substance inside the tank reservoir can be physically retained in the substances, in particular, by absorption. If, at the same time, the dangerous substance inside the tank reservoir can be transferred by means of a chemical reaction into a chemically modified state that prevents the ignition thereof by increasing the flash point, the discharging of the dangerous substance from the tank reservoir and the ignition thereof are prevented in a very effective manner.
