Title: Windshield removal assembly, method and blade for same
Inventor: OGSTON ALFRED JOHN
IPC: B26B7/00
Filed: 2006-04-28
Abstract: A windshield removal assembly, method and blade for same, with the thin metal blade having a unique delta-shape. The blade connects at its narrowed shank portion to the shaft of a reciprocating power tool. The blade has front and rear ends, the front end being substantially straight and wider than the blade rear end. The blade has substantially straight side edges which narrow from the front end to the rear end to about the width of the shaft. Arc portions are formed between the front end and each side edge of the blade. The top edge of the blade forms a non--sharpened top edge on the front end and arc portions, while the bottom edge of the blade forms a sharpened bottom cutting edge which extends across the front end of the blade and along at least half of the arc portions. The blade has sufficient rigidity to cut the urethane bed when reciprocated, and sufficient lateral flexibility to conform to the curved surface of the windshield when pressed thereagainst. The large arc portions, combined with the sharpened cutting edge extending substantially around the arc portions, improve cutting in a generally continuous lateral movement, especially around corners. The straight side edges preferably join the shank at a reduced angle to strengthen the blade, allowing it to be made in greater lengths without breakage.

Patent CA-2552286-A1 (CA)
Title: Ad hoc sensor networks
Inventor: TATESON JANE ELIZABETH
IPC: G01D9/00
Filed: 2004-12-22
Abstract: A plurality of mobile sensor devices each periodically measure a property of their environment, and determine the rate of change in that property.  Neighbouring devices also co-operate to determine the values of the property being measured by each other. If the property is invariant both over time and over a number of neighbouring devices, their periodicity of measurement-taking is reduced to conserve power for more significant measurement events. The devices may co-operate to relay their measurements to a data collection point.  Each device determines the level of data traffic being carried by one or more neighbouring devices, identifies the device that is carrying the least traffic, and puts itself under the control of that device. Any device that determines that it is carrying less such traffic than any of its neighbours assumes control of the data sensing rate for itself and those neighbours, and transmits control data to the said other devices to co-ordinate their data collection rates and stagger their data collection times.

Title: Systems and methods for providing distributed cache coherence
Inventor: BROMLING STEVEN
IPC: G06F15/173
Filed: 2005-07-07
Abstract: A plurality of access nodes sharing access to data on a storage network implement a directory based cache ownership scheme. One node, designated as a global coordinator, maintains a directory (e.g., table or other data structure) storing information about I/O operations by the access nodes. The other nodes send requests to the global coordinator when an I/O operation is to be performed on identified data. Ownership of that data in the directory is given to the first requesting node. Ownership may transfer to another node if the directory entry is unused or quiescent. The distributed directory-based cache coherency allows for reducing bandwidth requirements between geographically separated access nodes by allowing localized (cached) access to remote data.
