Patent CA-2160351-C (CA)
Inventor: MCEWAN THOMAS E
IPC: G01S7/285
Filed: 1994-04-08
Granted: 2006-04-04
Abstract: An ultrawide (UWB) receiver utilizes a strobed input line (14) with a sampler (10) connected to an amplifier (18). In a differential configuration (18), +UWB inputs (14a) are connected to separate antennas or to two halves of a dipole antenna. The two input lines (14) include samplers (10) which are commonly strobed (12) by a gating pulse with a very low duty cycle. In a single ended configuration, only a single strobe input line and sampler is utilized. The samples integrate, or average, up to 10,000 pulses to achieve high sensitivity and good rejection of uncorrelated signals.

Granted: 2004-07-13
Abstract: The infrared detector contains an emitter (4), a receiver (5) and an analysis circuit (2') having means (14 to 18) for obtaining a working signal (U n). The analysis circuit (2') contains a controller (29) for outputting a compensating signal (I k) superimposed over the incoming signal (I e), which on the one hand receives the working signal (U n) and on the other hand is connected to the output of the receiver (5), the compensating signal (I k) is selected so that the working signal (U n) is corrected to the value zero so that the maximum sensitivity is retained at all times. In a preferred embodiment, an analogue/digital converter (26, 30) is connected downstream of the controller (29), the analogue/digital converter (26, 30) on the one hand digitising the controller signal and on the other hand being connected to a digital/analogue converter (25, 32) for generating a voltage corresponding to the digital signal value in each case. This voltage determines the compensating signal(I k).

Abstract: An apparatus and a method for manufacture a double-sided three dimensional embossed web is provided, A web (15) is led through the nip between an embossing roller (18) and a pressure roller (19). The web (15) is preferably in a non-cured state and may be a paper or a plast web. If a pressure roller (19) having a smooth and hard surface is used, it has surprisingly created the effect of a double-sided three dimensional embossing. Such double-sided embossing gives the web a good hand and feel and a good drapability thereby making it suitable for manufacturing cloth, curtains, diapers and other products which should feel soft and pleasant and which should have a good drapability to be compared with that of knitwear and textiles. The embossed web would occur with the embossing or impressions (24) provided on two surfaces as a mirror image around a plane of symmetry (23) passing through the middle of the web (15). In the same way raised areas (26) would be opposed by raised areas (26).

Title: Method for dynamically allocating communication channel bandwidth between competing applications
Inventor: RAO R PADMANABHA
IPC: H04L47/43
Filed: 1995-05-19
Granted: 2000-08-01
Abstract: A statistical multiplexer (300) selectively passes packets of encoded data from a plurality of encoders (302) to a communication channel (330) so as to maximize the quality of the encoded data. A table is stored in a memory (313) of the statistical multiplexer (300) that has an entry for each unit of encoded data that can be transmitted over the communication channel (330) in a predetermined time interval. The statistical multiplexer (300) accesses each entry in the table to obtain a pointer, e.g., an address, to an encoder (302) that can transmit the next unit of encoded data to the communication channel (330). The statistical multiplexer (300) dynamically adjusts the data compression rate for each variable rate application so that the quality of all the encoded data streams are optimized over a window, and builds a new table that reflects the adjusted rates. In one application, the table is broken into a static table and a dynamic table.

Abstract: A compact gas-fired radiant space heater is adapted for residential use, having an output in the 20k BTU to 40k BTU/hr range and exterior dimensions small enough to allow it to be installed in a standard two foot by four foot suspended ceiling opening. A radiator tube having a total length of approximately 15 feet is bent into a serpentine shape, and combustion control components are housed within a plenum chamber supplying combustion air to the tube, both the tube and the chamber being encircled by a frame that fits within the two foot by four foot opening.      The combustion control components are attached to a chassis plate whereby the components are removable from the plenum chamber as a unit to enhance serviceability of the heater.      A burner venturi of novel configuration produces a flame that is less than four feet long yet which is relatively quiet. An air flow switch senses the dynamic pressure of an air stream issuing from a fan which pressurizes the plenum chamber, shutting off the supply of gas to the burner if the pressure reading indicates unacceptably low air flow.

Title: Reduced complexity signal transmission system

IPC: G10L19/12
Filed: 1997-01-31
Granted: 2006-03-28
Abstract: In a CELP coder a comparison between a target signal and a plurality of synthetic signals is made. The synthetic signal is derived by filtering a plurality of excitation sequences by a synthesis filter having parameters derived from the target signal. The excitation signal which results in a minimum error between the target signal and the synthetic signal is selected. The search for the best excitation signal requires a substantial computational complexity. To reduce the complexity a preselection of a small number of excitation sequences is made by selecting a small number of excitation sequences resembling the most a backward filtered target signal. With this small number of excitation sequences a full complexity search is made. Due to the reduced number of excitation sequences involved in the final selection the required computational complexity is reduced.
