Patent CA-2438252-A1 (CA)
Inventor: PELESKA PAVEL
IPC: G01R31/3185
Filed: 2003-08-26
Abstract: In a fault-tolerant system, single or multiple line faults between two assemblies (BG1, BG2), modules or circuits (IC1, IC2) should not lead to a system failure. In addition, it should be possible with minimal outlay to detect or repair a single line fault, or to change over to a fallback line, without impairing the redundancy of the system, its functionality or performance. Known solutions only achieve this by means of costly circuitry and by the provision of several additional lines (E). For instance, for a bus having a width of 64 bits, an 8-bit ECC is required to correct a single bit error. According to the invention, a detection method and a correction method as well as a circuit arrangement are provided which solve the problem by executing a checking routine on every single line (N, E), whereby all errors are reliably detected. By virtue of the reliable detection, only one additional fallback line (E) need be provided for each single line error to be corrected, to which fallback line a switchover is made in the event of an error.
Patent CA-2440988-A1 (CA)
Title: Determining a position of objects
Inventor: TAULU SAMU
IPC: G01B7/004
Filed: 2002-03-19
Abstract: The invention relates to a method for determining the location and/or orientation of objects in relation to each other. The invention is based on the use of signals generated by electromagnetic or acoustic transmitters attached to an object and measured by receivers of another object. As a result, the relative location and/or orientation of the objects can be calculated.    The invention allows determining amplitude distributions of signals sent by a set of transmitters and received by a set of receivers in a more precise and effective manner than prior art. The invention further allows choosing the signals to be transmitted more freely than prior art, especially in terms of frequency and phase since the signals to be transmitted do not have to be orthogonal with each other, unlike in prior art.

Patent CA-2458472-A1 (CA)
Title: Device address self-discovery
Inventor: ANDRESS MARK W
IPC: H04L29/10
Filed: 2004-03-24
Abstract: Some devices on modern-day, communications networks are unaware of their own address. Specifically, API are not provided to allow access to the internal address of the proprietary device. Many communications applications require peer-to-peer communication without a gateway, proxy, router or other middleware in between.  This is not possible without the device discovering its own internal address. This invention enables devices to discover their own internal address thereby facilitating such communication. The invention is a three-phase communications protocol between a device that does not know its own address (dumb device), another device on the same internal network that does know its own address (smart device) and, an Internet DNS-like service. The process yields the unknown address to the smart device, which returns the address to the dumb device, enabling self discovery of a device's internal address.

Title: Window guard with quick release latching system
Inventor: DOHERTY STUART
IPC: A62B5/00
Filed: 2004-06-11
Abstract: A quick release latched security window guard having a framework attached to a building exterior overlying a window is held with a cam latch system including a cam rod extending through the building wall, with an end protruding into a hollow member forming a part of the framework. A sliding latching sleeve is spring urged into a slot in the cam rod end to lock the framework in place. Rotation of a handle on the rod end within the building forces the sleeve back to be cammed out of the slot to release the framework. One or more fixed slotted latching posts may also be mounted to protrude into the hollow member and to be engaged by portions of the sleeve to form additional latching points, all of which are released by the rotation of a single cam rod. The framework may take the form of one or more ladder sections deployed to hang down from the window when the framework is pushed out after being released by the operation of the cam rod.
