Patent CA-2328054-C (CA)
Inventor: GORMLEY EAMONN
IPC: H04J11/00
Filed: 2000-12-11
Granted: 2008-02-05
Abstract: A method is provided for multiple remote units (RU)s to efficiently utilize resources on a shared OFDM high speed data channel without collisions. A collision occurs when two or more RUs transmit on the same frequency at the same time. The method defines two distinct states for accessing the channel. These are the Arbitration state and the Data Transfer state. A base station transmits a flag on the downlink to notify the RUs of which state is in effect. RUs having a data message notify the base station by transmitting a frequency tone, which acts as a request to transmit data, during the arbitration state. The tone frequencies are frequency spaced to be mutually orthogonal, so that the base station can receive all the uplink requests simultaneously. Upon receiving the uplink request signals, the base station establishes the data transfer state and orders the uplink data messages from the remote units is a non-interfering sequence. A system for preventing uplink data message collisions in an OFDM communications system is also provided.

Title: Search window delay tracking in code division multiple access communication systems
Inventor: POPOVIC BRANISLAV
IPC: H04B1/711
Filed: 1999-04-29
Granted: 2010-02-02
Abstract: The present invention provides a search window delay tracking procedure for use in a multipath search processor of a CDMA radio receiver. A channel impulse response is estimated for a received signal containing plural paths, each path having a corresponding path delay. A search window defines a delay profile that contains the plural paths of the received signal. A  mean or average delay is calculated for the estimated channel impulse response (CIR), and an error is determined between the mean CIR delay and a desired delay position corresponding to the center of the CIR search window. An adjustment is made to reduce that error so that the center of the search window and the mean CIR delay are aligned. The error may be processed either linearly (in one embodiment) or non-linearly (in another embodiment) to minimize the error and to reduce an influence of noise. A non-linear filtering process includes calculating a delay spread from the mean CIR delay calculated for successive processing cycles of a window delay tracking procedure corresponding to each new input. A difference is determined between the successive delay spreads. Adjustment signal is set equal to the error signal if the difference is less than or equal to a threshold.  Alternatively, the adjustment signal is set to zero if the difference is greater than the threshold. Consequently, if the delay spread in the current iteration is significantly different from the delay spread in the previous iteration, the new error sample calculated in the current iteration is considered unreliable, and no adjustment is made.

Abstract: A structural panel component, such as an aircraft fuselage shell component, includes a single integral part having longitudinal and crosswise stiffening elements integrally arranged on a skin sheet. This integral component has been formed by a high speed milling chip removal process applied to a solid plate-shaped semi-finished starting material. The skin sheet has areas of differing thicknesses, and the height, thickness, and spacing of the stiffening elements varies as needed, depending on the local loading conditions that will prevail on the finished structural component. The configuration of the component can be optimized to minimize the weight while satisfying all load strength requirements. The manufacturing method is very simple and economical.

Title: Portable, potable water recovery and dispensing apparatus
Inventor: FORSBERG FRANCIS C
IPC: E03B3/28
Filed: 2001-03-20
Granted: 2007-07-10
Abstract: A portable, potable-water generator for producing high-purity liquid water by condensation of dew from ambient air. The generator employs an air fiter to remove particulates and aerosols from the incoming air. An enclosed heat absorber cools the filtered air to its dew point and collects droplets of condensate into a combined condensate collector and storage reservoir. Before discharge, the collected dew is treated in a bacteriostat loop to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. A recirculation loop provides the ability to recirculate stored condensate during periods of inactivity. Further, quick disconnect fittings and variable length flexible tubing allows use of the invention to serve remote dispensers and/or appliances and allows use of municipal water treated through the apparatus in low condensate situations. All the subsystems are fail safe-interlocked to disable the generator immediately and prevent delivery of water if any one of them stops functioning within predetermined safe limits.

Abstract: A coated membrane for use in controlling the oxygen and carbon dioxide ratio inside of a package that holds respiring produce such as fruits, vegetables or flowers. The coated membrane comprises a porous substrate, such as a polypropylene film, and has an oxygen permeance in the range of 5,000 to 30,000,000 cc/100 in2-atmosphere-day. The substrate is coated with a materia l that is substantially impermeable to oxygen, such as an acrylic emulsion, so that the amount of substrate surface area covered with the coating causes a decrease in the oxygen permeance of the substrate. The coating is applied to the substrate using a flexographic or rotogravure or rotary silkscreen process. An aperture of approximately 0.15 mm is placed in the coated membra ne to allow the internal pressure to approximate the external pressure without a significant loss of relative humidity.

Abstract: The present invention provides a method and an apparatus for detecting a position of a light spot in a light distribution that can include stray ligh t components (e.g. from other lasers, ambient lighting etc.). The apparatus includes a continuous response position sensitive detector (CRPSD, e.g. lateral effect photo-diode) for determining a first centroid of the light distribution and a discrete response position sensitive detector (DRPSD, e.g . multiplexed array) for determining a second centroid of the light distributi on within a reading window defined about the first centroid and within the ligh t distribution. The second centroid represents the position of the light spot in the light distribution. This multiple stage approach exploits the high resolution and speed offered by traditional CRPSDs together with the accurac y under variable lighting conditions offered by traditional DRPSDs.

Abstract: The present invention uses the principle that phosphomolybdate binds to hydrophobic surfaces to isolate the phos-phomolybdate complex from other phosphate-containing molecules and further uses the SPA concept to bring a radiolabeled phos-phomolybdate complex in close contact with a scintillant for measurement by scintillation counting. Generally, the present invention provides an assay for detecting and measuring the amount of orthophosphate (Pi) in an aqueous reaction mixture, wherein the amount of Pi released is separated from the reaction mixture by: adding a solution of molybdate to the reaction mixture to form a phosphomolybdate complex; and contacting the phosphomolybdate complex with a hydrophobic surface, wherein the surface is capable of being separated from the aqueous reaction mixture to allow measurement of the Pi. Particularly, this invention provides an assay for measuring the ATPase activity of enzymes, more particularly, the HPV El helicase.
