Patent CA-2574208-A1 (CA)
Title: Improved multi-layer integrated rf/if circuit board
Inventor: COOPER MICHAEL
IPC: H05K1/00
Filed: 2005-07-20
Abstract: An improved multi-layered integrated RF/IF circuit board has been disclosed.  The board is fabricated beginning with a center layer of material. In a first preferred embodiment, the center layer is a rigid core material. In a second preferred embodiment, the center layer is a pliable non-conductive material.  For every layer added to the upper surface of the stack-up structure of the board, a corresponding layer of the same material is added to the lower surface of the stack-up structure. Thus, during the lamination process, both the upper and lower surfaces are primarily soft, pliable non-conductive material. These non-conductive layers absorb any stresses introduced during the lamination process. Thus, when cooled, the board has large area flatness.  Standard manufacturing processes can be used for each individual step in the fabrication of the board. Therefore, a multi-layered integrated RF/IF circuit board in accordance with the present invention can be fabricated inexpensively.

Title: Stabilized uv transparent acrylic composition
Inventor: YANG SHI-JUN
IPC: C08K5/09
Filed: 2005-09-08
Abstract: This invention relates to a UV stabilized transparent acrylic composition.  More specifically the acrylic composition is stabilized with a carboxylic acid compound, which prevents or delays deterioration of the acrylic composition from high intensity UV radiation. The carboxylic acid compound is preferably an alpha hydroxyl carboxylic acid compound. The delay or prevention of deterioration results in the transmission of more UV radiation through the acrylic composition for longer periods of time. The composition is especially useful for tanning and other applications requiring transmission of high levels of UV radiation and resistance to discoloration. It is also useful in optical cable, LCD displays, acrylic storage media, and in HID devices.

Title: Digital hearing aid system
Inventor: BROWN DAVID RICHARD
IPC: H04R25/02
Filed: 2002-04-11
Abstract: A digital hearing aid is provided that includes front and rear microphones, a sound processor, and a speaker. Embodiments of the digital hearing aid include an occlusion sub--system, and a directional processor and headroom expander. The front microphone receives a front microphone acoustical signal and generates a front microphone analog signal. The rear microphone receives a rear microphone acoustical signal and generates a rear microphone analog signal. The front and rear microphone analog signals are converted into the digital domain, and at least the front microphone signal is coupled to the sound processor. The sound processor selectively modifies the signal characteristics and generates a processed signal. The processed signal is coupled to the speaker which converts the signal to an acoustical hearing aid output signal that is directed into the ear canal of the digital hearing aid user. The occlusion sub-system compensates for the amplification of the digital hearing aid user's own voice within the ear canal. The directional processor and headroom expander optimizes the gain applied to the acoustical signals received by the digital hearing aid and combine the amplified signals into a directionally-sensitive response.

Patent CA-2586599-A1 (CA)
Inventor: ANDERSEN TOM JUUL
IPC: A01G27/00
Filed: 2005-11-03
Abstract: A device and a method for continuous and adjustable dosage of fluids at low pressure. The invention is self-cleaning and low tech. It consists of a tapering dosage unit in which a filling, which allows fluids to pass in the longitudinal direction of the dosage unit, is inserted. At the outlet end of the dosage unit, a venturi tube is located which clamps the filling and thereby create a nozzle opening that fits the fluids viscosity and the pressure for a given desired dosage. When the dosage unit clogs, a flushing can be obtained by either increasing the pressure of the fluid and thereby forcing a flexible dosage unit to increase the sectional area and allow cleaning or in the same way through a mechanical opening of the dosage unit.

IPC: H04L9/00
Filed: 2006-03-08
Abstract: A computer is adapted for use in different operating modes by configuring an output controller, such as a graphics processing unit, to screen output signals prior to presenting them to the output device. A secure environment in the output controller verifies a digital signature or a hash of the output signal to determine whether the output signal is compatible with the current mode of operation. Thus only authorized output signals are presented when the computer is operating in a limited function mode, such as when metered usage time is expired. The apparatus and method also disclose similar output signal screening for determining whether the computer should be returned from a standby, or no-metering, mode to an active, or metered mode.
