Title: Hydrogen absorbing alloy powder and method of producing hydrogen absorbing alloy powder
Inventor: IBA HIDEKI
IPC: B22F1/145
Filed: 1997-09-26
Abstract: A method of treating surfaces of a hydrogen absorbing alloy and, particularly, a method of treating surfaces of a hydrogen absorbing alloy by enhancing the resistance of the surfaces of the powder against contamination such as oxide film, moisture and adsorptive gases when the alloy powder is being treated in the open air. In pulverizing or in treating a powdery hydrogen absorbing alloy or in producing a powder by the quickly quenched coagulation, the hydrogen absorbing alloy is treated in an atmosphere containing an SF6 gas to form a protection film containing at least a sulfide or a fluoride on the surfaces of the hydrogen absorbing alloy in order to enhance resistance against contamination. The method comprises a step for containing the hydrogen absorbing alloy in a container to pulverize it by hydrogenation in a hydrogen atmosphere, a step for dehydrogenation by evacuating the container, and a step for heat-treating the hydrogen absorbing alloy in an atmosphere containing the SF6 gas in the container.

Patent CA-2286541-A1 (CA)
Title: Apparatus, method and system having reduced power consumption in a multi-carrier wireline environment
Inventor: TATE CHRISTOPHER NEVILLE
IPC: H04B1/38
Filed: 1999-10-18
Abstract: To reduce power consumption and associated heating in a line card of line termination equipment (LTE, 12) employing multiple sub-channel carriers to communicate broadband information to customer premise equipment (CPE, 30) down a wireline communication resource (26), sub-channel carrier transmissions are restricted (58) during periods of CPE inactivity. Power supplies to a power amplifier (30) associated with the line card and wireline resource (26) are reduced, with digital signal processing capabilities of the LTE (12) further restricted (64). When the CPE  wishes to re-start communication, the CPE (30) locks (68) to a correct alignment in a transmission scheme using a pilot tone that is transmitted within a simple pattern sent during reduced sub-channel carrier transmissions. Alternatively, should all transmission from the LTE cease during CPE inactivity, then the CPE monitors (80) the transmission environment and sends (82) a wake-up call to the LTE between boundaries of an uplink slot.  The LTE (12) re-establishes pilot tone transmissions (86), with synchronisation and lock (88) subsequently achievable by the CPE (30); this is illustrated in FIG. 2.
Patent CA-2289748-A1 (CA)
Title: Cable with impact-resistant coating
Inventor: CAIMI LUIGI
IPC: H01B7/00
Filed: 1998-05-08
Abstract: The present invention relates to a coating for cables which is capable of protecting the cable against accidental impacts. By inserting into the structure of a power transmissioncable a suitable coating of expanded polymer material of adequate thickness, preferably in contact with the sheath of outer polymer coating, it is possible to obtain a cable which has a high impact strength. The Applicant has moreover observed that an expanded polymer material used as a coating for cables makes it possible to obtain a higher impact strength for this cable than using a similar coating based on the same polymer which is not expanded. A cable with a coating of this type has various advantages over a conventional cable with metal armor, such as, for example, easier processing, a reduction in the weight and dimensions of the finished cable and a lower environmental impact as regards recycling of the cable once its working cycle is over.

Filed: 1999-03-29
Abstract: Afin de réduire la puissance de crête pour la transmission multicode, l'amplitude est convertie du côté émission, et un estimateur servant à compenser la distorsion due à la conversion est placé du côté réception. Dans un procédé associé, le calcul MOD pour chaque puce est effectué du côté émission, et l'amplitude perdue par le MOD est estimée du côté réception, ceci réduisant la puissance de crête à un neuvième (1/9). Pendant l'estimation de l'amplitude perdue par le calcul MOD, il est déterminé le multiple impair ou pair le plus vraisemblable du dénominateur du MOD parmi tous les codes utilisés.

Title: Tunable optical fiber gratings device
Inventor: LONG PIN
IPC: G02B6/02
Filed: 1999-11-25
Abstract: A tunable optical fiber grating device for tuning optical characteristic responses of an optical grating area of an optical fiber includes an elongated beam member defining a neutral plane with a first and a second ends and adapted to receive the fiber' therealong. A securing member continuously secures the grating area all along the beam member between its ends and generally parallel to the neutral plane to allow for transmission of a bend of the beam member about the neutral plane to the grating area. A fixed support member has a screw for releasably securing the first end of the beam member within the neutral plane, and a mobile support member has a slotted element to slidably receive the second end of the beam member within the neutral plane.   The mobile support member displaces the second end relative to the first end substantially perpendicularly to the neutral plane to bending the beam, thereby stretching or compressing the grating area for tuning the optical characteristic responses of the optical fiber depending on the direction of the bend.

Patent CA-2297119-A1 (CA)
Inventor: DOMANIK RICHARD A
IPC: G01N33/48
Filed: 1998-07-17
Abstract: A clinical laboratory integrated screening and diagnostic system for preprocessing and inspection of cytological samples or other specimens. A processor receives digital images of each specimen and, using statistical analysis, estimates probabilities of atypia for objects or regions contained in the specimen. Based at least in part on these probabilities, the procesor then estimates a probability of atypia for the specimen as a whole. A specimen having high enough estimated probability of atypia is automatically categorized as suspicious or abnormal and is in turn screened by a human technician with the assistance of a preview system and a computer-assisted microscope workstation. A sample with sufficiently low or no probability of atypia is automatically categorized as apparently within normal limits and is then either screened by a human technician for quality assurance or automatically reported as within normal limits. After screening by the human technician, samples that the technician deems to be suspicious or abnormal are reviewed by an expert for final diagnosis.
