Abstract: A relaxation oscillator, such as a voltage controlled oscillator (VCO), with automatic swing control feedback which dynamically monitors the voltage swing across a capacitor and adjusts the oscillator threshold voltage, at which reversal of the polarity of the charging/discharging current occurs, to maintain the effective voltage swing at a constant level. The improved relaxation oscillator provides a very wide linear range of frequency variation versus control voltage (or current) and allows for the extendibility of linear operation to or near the maximum frequency that can be practically achieved by the oscillator circuitry.

Abstract: A filter media system, which is capable of operating in the microfiltration regime, offers: low cost, durability, high temperature and chemical resistance, no particulation, mechanical strength, separation efficiency, and biocompatibility. A filter media system is comprised of a carbon or ceramic composite substrate (1) which contains a carbon or ceramic matrix reinforced with carbon or ceramic fibers. The composite has an array of carbon or ceramic fiber whiskers (2) grown onto its surface or in its bulk. A process is provided for manufacturing the filter media system wherein a carbon fiber is disposed in a matrix deposited by a CVI or LPI process, at temperatures of about 900 to about 1200 ~C to achieve a weight gain of about 10 to 200 % (the ceramic matrix is deposited by a CVI process from an aqueous slurry or by use of a pre-ceramic polymer). This composite is treated with an aqueous solution of metal catalyst salt and is then heated in hydrogen at elevated temperatures to reduce the metal salt to metal. Whiskers are then grown on the surface or in the bulk of the catalyst deposited composite such as by decomposition of methane gas using metal catalyzed chemical vapor deposition (CVD).

Patent CA-2291863-A1 (CA)
Title: A linear amplifier arrangement
Inventor: SMITH HOWARD J
IPC: H03F1/32
Filed: 1999-12-07
Abstract: This invention relates to high power linear amplifiers. A high power linear amplifier is disclosed for communications such as CDMA communication systems. In accordance with the invention, there is provided a linear power amplifier comprising a power amplifier, a feedback circuit and a control element; wherein the architecture proposed uses an envelope detector to generate a baseband signal representing the amplitude envelope of the system input RF signal. This is digitised and used to generate phase and gain correction signals. The correction signals modulate the input signal to create a pre-distorted signal: which is applied to the power amplifier for amplification. The pre-distortion is such as to cancel the AM-AM and AM-PM distortion of the power amplifier thus resulting in an amplified output of improved spectral purity. In order to achieve the very high levels of spectral purity required by 3G cellular and multi-carrier 2G cellular systems, the correction coefficients in the lookup table need to be very precisely set. The method proposed incorporates an adaptation system whereby the pre-distorter can 'learn' the contents of the lookup table as it operates.

Inventor: MATSUMOTO WATARU
IPC: H04M11/00
Filed: 1999-04-01
Abstract: An on-hook/off-hook detector circuit (61) detects the voltage level of a telephone line (C) to determine whether the speech band is in on-hook or off-hook state, and produces a state signal (81). TEQ (63), FEQ (66) and constellation encoder gain scaling (67) perform adaptive equalization, bit distribution and gain distribution in time and frequency regions for data communication by using separate tables (75-80) depending on the state signal (81). Since the telephone is not used in on-hook state, the transmission subcarrier band for communication is shifted near, or expanded into, the speech band.

Inventor: REEVE HAROLD GORDON
IPC: G08G1/087
Filed: 2000-03-23
Abstract: The "Emergency Vehicle Traffic Signal Control" is simply a device that enables emergency vehicles such as ambulance, fire, and police to automatically control traffic signals at an intersection to safely direct the flow of traffic and better accommodate the driver of the emergency vehicle to proceed through a given intersection in a much safer capacity and in much less time than currently is occurring. Faster response to the scene of an emergency will save billions of dollars in property losses; but more importantly will save lives and decrease injury complications. This device will also greatly enhance the safety of all emergency vehicle personnel, motorists and pedestrians.     One feature incorporated in the "Emergency Vehicle Traffic Signal Control" is that is fully capable of controlling traffic lights in the same pattern that is currently occurring. There are no extra outward signals required, appearing to the public motorist and/or pedestrian. Therefore, the general public needs no teaching as to the function of the new system, thus reducing startup costs.
