Title: A duct cover for directing a fluid therethrough and a method for making the same
Inventor: TONI DARRYL M
IPC: B29D24/00
Filed: 1994-08-24
Abstract: A duct cover (12) for use with a duct (4) within a vehicle, the duct cover (12) operative for directing a fluid flow. The duct cover being further operative for minimizing the entrance of foreign object debris into the duct (4). The duct cover (12) has a flow directing honeycomb portion (16) for conducting the passing fluid flow in a preferred direction. The flow directing honeycomb (16) comprises an array of continuous, polygon shaped open cells (20) which are biased with respect to the initial fluid flow direction. The periphery (17) of the flow directing honeycomb (12) is rigidized to stiffen the same for minimizing the displacements thereof. The rigidity is provided by a framing member comprising upper and lower skin structures (28, 29) affixed to a core material (30). The framing member is preferably adhesively bonded to the flow directing honeycomb (16) by means of a foaming adhesive (36) and a barrier member (38). The barrier member (38) is operative for minimizing the expansion of the foaming adhesive (36) into the open cells (20) of the honeycomb (16). In order to improve the low observability characteristics of the structure, the cells (20) of the flow directing honeycomb (16) are preferably coated with a radar absorbent material, such as carbon, which acts to minimize the amount of electromagnetic energy that is reflected therefrom.

Patent CA-2184646-A1 (CA)
Inventor: WILLIAMS THOMAS H
IPC: H04L5/02
Filed: 1996-09-03
Abstract: A communication method enables a plurality of remote locations to transmit data to a central location. The remote locations simultaneously share a channel and there is a high degree of immunity to channel impairments. At each remote location, data to be transmitted is coded by translating each group of one or more bits of the data into a transform coefficient associated with a frequency in a particular subset of orthonormal baseband frequencies allocated to each remote location. The particular subset of orthonormal baseband frequencies allocated to each location is chosen from a set of orthonormal baseband frequencies. At each remote location, an electronic processor performs an inverse orthogonal transform (e.g., an inverse Fourier Transform) on the transform coefficients to obtain a block of time domain data. The time domain data is then modulated on a carrier for transmission to the central location. Preferably, the time intervals for data transmission at the different remote locations are aligned with each other. In one embodiment of the invention, all of the baseband frequencies are allocated to a single particular remote location for one time slot. At the remote location, data is received from a plurality of remote locations. The data is demodulated to obtain baseband time domain data. The orthogonal transform is performed on this data to obtain transform coefficients. Each transform coefficient is associated with a baseband frequency. The central location keeps track of which baseband frequencies are allocated to which remote location. This enables the transform coefficients of each remote location to be translated back into the data stream of that remote location.

Patent CA-2196938-A1 (CA)
Title: Distortion-free chopper-based signal mixer
Inventor: HIRSCHENBERGER FRANK M
IPC: H03D7/12
Filed: 1997-02-06
Abstract: An AM-modulated carrier signal is converted to a lower carrier frequency through mixing with a square wave local oscillator signal.  A field-effect transistor chops the modulated signal according to the square wave signal so that a chopped or sampled version of the modulated signal is created without passing the signal through a semiconductor junction.  A filter then selects the desired mixing product.  Thus, a distortion free mixing of the signal is obtained using low cost components including a JFET switch and a square wave output from a microcontroller.
