Patent CA-2232392-A1 (CA)
Title: Infrared radiation modulating device
Inventor: MANNING PAUL ANTONY
IPC: G02F1/015
Filed: 1996-09-09
Abstract: A non-mechanical modulating device for use in infrared detection. The device is of particular use in the 8-14 µm range and has application in thermal imaging cameras and gas sensing systems. The modulator comprises a germanium element and a means of varying the carrier concentration. In particular, the variation of the hole concentration gives rise to the absorption of infrared radiation due to interband transitions between the light and heavy hole bands in the split valence band in germanium. The variation in hole concentration may be initiated in any convenient way, for example, by the irradiation of the germanium with visible or near infrared light, by the electrical injection of free carriers across a germanium diode structure or by electron impact on the germanium surface following acceleration under vacuum. In the case where the variation in carrier concentration is initiated by optical means, the surface of the germanium is treated so as to produce a low surface recombination velocity.

Patent CA-2242823-A1 (CA)
Inventor: TORKELSSON MATS
IPC: G06F17/14
Filed: 1996-02-26
Abstract: A real-time pipeline processor, which is particularly suited for VLSI  implementation, is based on a hardware oriented radix-22 algorithm derived by integrating a twiddle factor decomposition technique in a divide and conquer approach. The radix-22 algorithm has the same multiplicative complexity as a radix-4 algorithm, but retains the butterfly structure of a radix-2 algorithm.  A single-path delay-feedback architecture is used in order to exploit the spatial regularity in the signal flow graph of the algorithm. For a length-N  DFT transform, the hardware requirements of the processor proposed by the present invention is minimal on both dominant components: Log4N-1 complex multipliers, and N-1 complex data memory.

Patent CA-2245848-A1 (CA)
Title: Improved fluid overfill probe
Inventor: BENTON FRANCES H
IPC: G01F23/292
Filed: 1997-02-06
Abstract: An optically-based overfill detection probe is provided that has a prism with a substantially quadrilateral cross-sectional shape, such that internal reflection angles are less than ninety degrees. The prism is made of a fluoropolymer, preferably Teflon® PFA, and uses an infrared optical signal. The prism material has a high resistance to chemical solvents, has high signal transmission in the infrared (IR) wavelength range, is less prone to condensation and frost than plastic or glass, and enables the production of prisms at significantly less cost than glass. The substantially quadrilateral cross-sectional shape of the prism, in itself, has the advantage of allowing angles of incidence much less than ninety degrees on internal prism surfaces, thus reducing signal loss from surface irregularities. The probe also includes a two-piece housing structure that compresses an outwardly-extending portion of the prism material to firmly hold the prism in place, and force the material into sealing contact with an inner surface of the housing. The housing has an elongate portion which encompasses the prism, and which extends toward the fluid, preventing any light which escapes the prism from being externally reflected back to the photodetector of the probe.

Title: Charge balance device
Inventor: DERRYBERRY ANDY L
IPC: F25B41/06
Filed: 1998-10-08
Abstract: The present invention is a charge balance device for a heat pump. The heat pump system has a heating and a cooling mode and includes an indoor heat exchanger, an outdoor heat exchanger, a compressor, refrigerant circuitry connecting the heat exchangers and the compressor in series arrangement, with the charge balance device connected in parallel arrangement with the outdoor heat exchanger. An accumulator is connected in line with the refrigerant circuit at a point immediately upstream of the suction side of the compressor for storing excess liquid refrigerant during heating mode. The charge balance device includes a check valve for blocking refrigerant flow, thus preventing the diversion of refrigerant flow around the outdoor heat exchanger during cooling mode, and a restrictor orifice for throttling refrigerant flow, thus regulating the flow of refrigerant diverted around the outdoor heat exchanger during heating mode. The check valve and restriction orifice are integrally formed for diverting a regulated portion of liquid refrigerant around the outdoor heat exchanger during heating mode such that excess liquid refrigerant is allowed to be stored in the accumulator at a relatively low pressure.
Patent CA-2250010-A1 (CA)
Title: Denaturants for sympathomimetic amine salts
Inventor: BESS WILLIAM S
IPC: A61K47/34
Filed: 1997-04-01
Abstract: The present invention is directed to the addition of one or more pharmaceutically and biologically acceptable denaturants to sympathomimetic amine salt-containing pharmaceutical products to make these products less suitable as starting materials for the production of illegal drugs. In one preferred embodiment, the denaturant(s) and the sympathomimetic amine salt exhibit similar chemical and/or physical properties, so that purification of sympathomimetic amine by conventional extraction techniques is rendered difficult or essentially infeasible. In another preferred embodiment, the denaturant physically interferes with the extraction of the sympathomimetic amine salt from the pharmaceutical products i.e., emulsifies and/or alters the viscosity of the pharmaceutical products in solution). Because the separation of denaturant(s) from the sympathomimetic amine salts is rendered impracticable, attempts to isolate the sympathomimetic amine salts from compositions of the invention are unsuccessful or results in preparations that are converted into adulterated illegal drug products.  The present invention is directed to denaturant-containing sympathomimetic amine products and to methods for their preparation. The denaturant-containing sympathomimetic amine products are used for known indications treated by sympathomimetic amines.

Title: Wide band transmission through wire
Inventor: SHIVELY RICHARD ROBERT
IPC: H04B3/32
Filed: 1998-04-03
Abstract: A method for broadband transmissions through metallic wire in an interference-laden environment. Wideband communication through a wire is achieved in the presence of other wideband signals in the wire or in adjacent wires by applying a modulation schema to the wideband communication signal that forms a signal which is orthogonal or nearly orthogonal to all other signals that are present in the wire, whether directly applied or electromagnetically induced.  In accordance with one illustrated embodiment, a CDMA code is applied to the wideband signal that is to be communicated through a given wire, and the code that is employed is orthogonal to the CDMA codes that are applied to other signals that flow through the wire or through other wires which are in the neighborhood of the given wire.
