Patent CA-2407766-A1 (CA)
Inventor: THIBEAULT CLAUDE
IPC: G01R31/30
Filed: 2001-11-20
Abstract: A method and system for Vddq Integrated (IC) testing are described herein.

Depending on the approximated voltage value, the IC may be determined faulty or not.
Patent CA-2415747-A1 (CA)
Inventor: PASLAWSKI DEAN M J
IPC: A01M23/34
Filed: 2003-01-23
Abstract: In a trapping device for the harvest of furbearing animals, it is known to have a snare cable depending from the spring to freely embrace the travelling animal's neck and tighten quickly. In this invention, a steel rod is secured to the spring such that they extend parallel when the spring is compressed, and perpendicular when the spring is tripped. The top end of the rod is used as a brace for an end of the snare cable where they are attached by inserting the cable through a hole and clamped by an aluminum ferrule. The bottom end of the rod, which extends a few inches below the attached spring, is used as a stake for positioning the set snare. The spring is drawn back towards the steel rod, manually, by his or her own strength and a steel safety hook attached to the rod is used to grasp the spring's shaft.      The top of the spring is made into a loop that encircles a grooved slot. The cable attached to the rod passes through the loop, fits into the slot, and is held by a steel ferrule under the pressure of the spring. Once the stake end is pushed into the ground or snow with the snare positioned properly, the safety hook must be removed to allow the spring to "fire" when the cable is jerked by the snared animal. A chain attached to the rod is used to fasten this device to a tree or other object to advoid being carried off. The option of a steel clip attached to the top of the rod may be designed for easy replacement of the snare cable.

Title: System and method of fault management in a mobile communications network having a proxy switch
Inventor: NAQVI SHAMIM A
IPC: H04M3/00
Filed: 2001-11-21
Abstract: A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. A FSN and a BSN are provided for communication with the MSC, and another FSN/BSN pair are provided for communication with the BS. Logic detects whether a received message is a change over order message (COO) from one of the MSC and BS, indicating a break in a first signaling link between the proxy switch and the one of the MSC and BS, and logic generates and sends a COA message to the one of the MSC and BS containing the BSN maintained by the switch for communication with the one of the MSC and BS. Fault emulation logic forces a break in a second signaling link between the proxy switch and the other of the MSC and BS, wherein the second signaling link is configured to correspond to the first signaling link, and generates and sends a new COO message to the other of the MSC and BS.

Title: Adjustable resilient blade support
Inventor: PITT RICHARD E
IPC: D21F1/48
Filed: 2001-12-14
Abstract: An adjustable resilient blade support for use in the forming section of a papermaking machine. The blade support is adjustable, both to allow the attached blade to be moved from a position where it is out of contact to a position where it is pressed into contact with the adjacent forming fabric, and to permit adjustment of the blade orientation relative to the surface of the forming fabric. The blade support is also resilient, and thus allows the blade to respond to transient localised changes in the path of the forming fabric with which it is in contact. The adjustable resilient blade support of this invention is thus of use in an open surface forming section, and also is of use in forming sections in which two forming fabrics are used.
