Patent CA-2245976-A1 (CA)
Title: Symmetric multi-processor system and method
Inventor: VAN DER VEEN PETER H
IPC: G06F9/46
Filed: 1998-08-26
Abstract: The present invention relates generally to computer operating systems, and more specifically, to operating system calls in a symmetric multiprocessing (SMP) environment. Existing SMP strategies either use a single lock or multiple locks to limit access to critical areas of the operating system to one thread at a time. These strategies suffer from a number of performance problems including slow execution, large software and execution overheads and deadlocking problems. The invention applies a single lock strategy to a micro kernel operating system design which delegates functionality to external processes. The micro kernel has a single critical area, the micro kernel itself, which executes very quickly, while the external processes are protected by proper thread management. As a result, a single lock may be used, overcoming the performance problems of the existing strategies.
Patent CA-2249388-A1 (CA)
Title: Circuitry and method for initiating communication between communication stations of a radio communication system
Inventor: WANG YI-PIN ERIC
IPC: H04B7/185
Filed: 1997-03-28
Abstract: A method and associated circuitry for initiating communication between a network station and a user terminal of a radiotelephonic communication system, such as a satellite-cellular communication system. When communication is to be initiated, a paging signal is transmitted by a network station to the user terminal. When the user terminal detects the paging signal, an acknowledgment signal is generated by the user terminal and encoded to increase the margin of the acknowledgment signal. An increased-margin acknowledgment signal acknowledging reception of the paging signal is transmitted to facilitate communication of the acknowledgment signal back to the network station.

Patent CA-2254327-A1 (CA)
Title: In-line roller skate
Inventor: ANDREA GABRIELLI
IPC: A43B5/04
Filed: 1998-11-20
Abstract: An in-line roller skate, which comprises a rigid shell wherein a flexible inner shoe is housed. The latter is advantageously lined at the level of its leg portion by a cover, thereby defining a sheath substantially open downward, in which the upper part of the shell is housed. In this way, when the skater's ankle bends forward, it is supported by the inner shoe because of the interference arising between the cover and the upper part of the shell. This allows a great freedom of movement in a longitudinal direction for the skater's ankle, which can be bent even in a very accentuated manner, differently from what occurs in the known skates, where the bottom of the leg is enclosed in a rigid leg portion. At the same time, good support is maintained in a lateral direction owing to the upper part of the shell which allows the transmission of the guiding movements. According to a preferred embodiment, the cover may be hinged to the shell in the malleolar regions.

Inventor: LEHTINEN PEKKA
IPC: H04Q3/545
Filed: 1997-08-29
Abstract: The invention relates to a method of handling the event recordings in a service database system. The database contains stored measurement tables (MT) which include consecutive rows (Ri). So that the activation values of individual objects can be changed or individual objects can be added/deleted at any time causing as little interference as possible to the measurement, the value of the activation parameter of the measurement object is stored on the row and the zeroing of the counter groups of the measurement object is performed during the recording and zeroing phase of the counters so that for each counter group of the measurement object the first processing after the activation of the measurement object in question is forced to be such that the recording of the counter group is blocked, but the zeroing of the counter group is allowed.

Title: Biocular viewing system with intermediate image planes for an electronic display device
Inventor: HEBERT RAYMOND T
IPC: G02B5/30
Filed: 1999-03-31
Abstract: Low-cost complex plastic optics allow biocular viewing of video images generated by a single electro-optic display device, such as in a head-mounted display (HMD) for commercial or medical viewing applications.      A dual off-axis configuration uses nearly collimated illumination optics and intermediate imaging optics to fill both eyepieces from a single display device without the need for a beamsplitter. Multiple illumination schemes are provided for either monochrome or color, and in either two-dimensional or time-sequential true stereographic presentation. Light from multicolor sources is superimposed, mixed, and homogenized by mixing light comes with diffractive collectors. Offsetting color overcorrection and undercorrection of individual optical elements achieves overall chromatic correction with minimal optical element complexity. A wireless video signal interface eliminates excess cabling. Additional features include lightweight achromatic eyepiece construction and interchangeable lenslets for peripheral vision correction. Multiple optical elements are injection-molded as a unitary plastic structure, thereby reducing cost and complexity.
