Patent CA-2278833-A1 (CA)
Title: A method for extending the range of a wireless communication system
Inventor: KUO WEN-YI
IPC: H04B7/02
Filed: 1999-07-23
Abstract: The present invention is a method for extending a cell radius or access range of a base station without incurring ASIC correlator re-design. This is accomplished using a modified timing protocol that will cause signals transmitted by mobile-telephones positioned beyond the limitations of the ASIC correlator bit limitation to be received within a search window so the signals may be detected and demodulated. In one embodiment, the modified timing protocol incorporates a timing advance technique in which the base station transmits its signals at an advanced time before frame boundaries such that signals transmitted by out-of-range mobile-telephones can be received within a search window beginning at a frame boundary and spanning a time interval corresponding to the ASIC correlator bit limitation. In another embodiment, the modified timing protocol incorporates a shifted search window that begins at an advanced time after a frame boundary and spans a time interval corresponding to the ASIC  correlator bit limitation.

Title: Method and apparatus for performing soft hand-off in a wireless communication system
Inventor: PADOVANI ROBERTO
IPC: H04W36/18
Filed: 1998-01-27
Abstract: A method and apparatus for providing soft hand-off in a mobile communication system. In current systems, members of an active set of base stations (4, 4A, 4B, 4C) are determined by comparing measured pilot energy with fixed thresholds. The value of providing a redundant communication link to a mobile station (2) primarily depends on the energy of other signals being provided to the mobile station (2). In the present invention, the signal strength of each signal transmitted by other base stations (4, 4A, 4B, 4C) in communication with a mobile station (2) is considered when determining whether to add a base station to the set of base stations (4, 4A, 4B, 4C) in communication with the remote station. A base station is added only if the signal received from that base station provides sufficient added value to justify the impact on system capacity.

Abstract: The invention relates to a method for controlling the AlF3 content in cryolite melts for aluminium reduction, during which the temperature of the melt is measured. To be able to provide a highly accurate method which allows for aluminium reduction to be carried out at the lowest possible temperature, i.e. saving as much energy as possible, the invention provides for the Liquidus temperature to be measured and compared with a first setpoint value. AlF3 is added to the bath if the Liquidus temperature measured is higher than the first setpoint value, and the measured Liquidus temperature is compared with a second setpoint value which is lower than the first if the Liquidus temperature measured is lower than the first setpoint value. NaF or Na2CO3 is added to the bath if the Liquidus temperature measured is lower than the second setpoint value.

Inventor: VICE MICHAEL WENDELL
IPC: H03D7/12
Filed: 1998-09-09
Abstract: A high dynamic range mixer apparatus (60) and mixing method where a wide high dynamic range is achieved in part due to the use of series pair of switching devices (61, 62) that are matched so as to afford complete or substantial cancellation of nonlinearity distortion. The inventive structure and method preserve the compensation and cancellation mechanism of the series pair of back-to-back connected FETs (61, 62) without the need for either an intermediate frequency (IF) balun or a radio-frequency (RF) balun. Typically the switching devices are FETs (61, 62), such as for example MESFETs, connected source-to-source with one drain terminal (D2) grounded, and a non-grounded or floating switching signal applied between the common gate and the common source terminals.

Filed: 1999-08-18
Abstract: The linking component between two parts that contributes to maintaining them at a distance that is determined but adjustable comprises a jack with a screw and a nut. The movement of the jack is controlled by a motor. Universal joints are disposed between the two parts and the screw and the nut respectively, and the axes of rotation of one of the universal joints passes through the center of the nut. If play present in the assembly causes the screw to become skewed relative to the nut, the nut tilts freely until its axis is in line with that of the screw, thereby eliminating the flexion stresses caused by the cantilever on the screw. The component may be used to regulate the angle between two hinged sections of a robot arm.

IPC: G01M11/00
Filed: 1998-11-03
Abstract: An interferometer array includes a plurality of interferometer sub-arrays, each sub-array including a plurality of interferometers.      Each interferometer in a sub-array is implemented with a respective pair of fiber Bragg gratings and a sensing length of optical fiber positioned between the respective pair of fiber Bragg gratings.      The fiber Bragg gratings in each respective pair of fiber Bragg gratings have the same characteristic wavelength that is different from the characteristic wavelength of every other pair of fiber Bragg gratings in the sub-array. The sub-arrays are interconnected to minimize the common-wavelength crosstalk between the sensors in the overall interferometer array. In one embodiment, the sub-arrays are connected in series along a common length of optical fiber such that the maximum common-wavelength crosstalk is limited by the number of sub-arrays connected in series. In a second embodiment of the invention, branches are interconnected to a common input/output optical fiber via optical couplers, and each branch has one or more sub-arrays connected in series. The common-wavelength crosstalk is limited by the number of arrays in each sub-array. In a third embodiment of the invention, branches are interconnected between an input optical fiber and an output optical fiber via optical couplers, and each branch has one or more sub-arrays connected in series. Optical signal delay elements are positioned in the input optical fiber to incrementally increase the delay experienced by an input optical signal before it reaches each successive branch connected to the input optical fiber. Therefore, the return optical signals from each sub-array in a branch are separated in time from the return optical signals from the sub-arrays in the other branches.

Abstract: Apparatus and methods for improved in-line contaminant removal from engine lubricating oil are provided which employ gravity to achieve a desired flow rate of oil. The invention is adapted for use with an existing engine oil lubrication system and continuously processes a side stream that, after processing, is returned to the engine oil. During processing the oil is first filtered in filter assembly structure (121) and then drained and deposited upon the upper central surface portion of a heated dome platen (165) whereon the oil forms a thin film from which relatively low boiling volatile impurities are rapidly separated in a gaseous state. The gas is vented through upper outlet (169) and conduit (171) while the recovered reconditioned oil is collected on bottom platform (163) and recycled through return conduit (164).

Abstract: A circuit (202; 204) for transferring high voltage analog video signals whil e enabling the use of conventional low voltage logic levels includes a first transistor (308; 308') powered by a high voltage power source to bias a pass  transistor (114; 124) at a high voltage level. The pass transistor receives a high voltage video signal and because of the high voltage bias is able to pa ss the video signal without attenuation of the signal due to feedthrough effect s, thus preserving the fidelity of the video signal. A second transistor (304; 304') provides a ground potential which operates to turn OFF the pass transistor, thus disabling the transfer of the video signal therethrough. A third transistor (306; 306') operatively coupled to the first transistor operates to turn OFF the first transistor when the second transistor is in operation.
