Patent CA-2300722-A1 (CA)
Inventor: FOULGER STEPHEN H
IPC: H01B1/12
Filed: 2000-03-15
Abstract: An electrochemical sensor which is tailored for sensitivity to specific chemical analytes by selecting proper constituents. The electrochemical sensor is comprised of an immiscible polymer blend of at least two polymers in which a conductive filler is dispersed in one of the polymers of the blend through a multiple percolation approach to compounding. When in the presence of a chemical analyte which is in either a liquid or vapor phase, one phase of the dual immiscible polymer blend swells, effecting a decrease in the conductivity, or increase in resistivity, of the polymer blend. The electrochemical sensor is reversible in that when the chemical analyte evaporates or is removed, the polymer blend returns to its original conductivity. With the multiple percolation approach it is possible to make a single composite material identifiably sensitive to various chemical analytes by incorporating several major phase materials into the immiscible polymer blend, each having an affinity for swelling for a different analyte. Further, the multiple percolation approach allows sensors to be made at extremely low cost.

The valve is preferably used in a vibration damper. One damper includes a body, a piston, first and second chambers, a damping valve, a piston rod, an auxiliary chamber, a passageway interconnecting to the auxiliary chamber, a field responsive fluid, a field responsive fluid valve for controlling flow to the auxiliary chamber, and pressurization means. Preferably included is a cavity partition having field responsive fluid disposed on one side and non-field responsive fluid disposed on the other. This allows a reduction of MR fluid allowing use of lighter-weight, less-expensive, hydraulic fluids for flow through the piston's damping valve. In another aspect, the damper includes mechanical adjustment means for manually adjusting the damping level.  Adjustment is accomplished by a moveable permanent magnet, moveable pole piece, moveable pole-and-magnet assembly, or magnetic shunt. Manual adjustment may include a knob, lever, or cable actuation. Alternately, magnetic flux is provided by an electromagnet. The valve and damper finds utility in any suspension system where a damper body is attached to a frame component, such as a bicycle frame, and the piston rod is attached to a suspension component, such as a bicycle's swingarm.

Inventor: GORDON RAYMOND H
IPC: F02M33/00
Filed: 2000-08-08
Abstract: This invention was developed to alter the molecular structure of hydrocarbon fuels by breaking down the long hydrocarbon chain molecules which gives them more exposure to oxygen and thereby creates more energy.  All combustion fuels require oxygen but existing fuels have to be designed to minimize evaporation to allow handling in the open. The gasoline used today, that is available at the service station pumps, has longer hydrocarbon chain molecules or the evaporation would be much higher which could create the right circumstances for dangerous explosions. This invention achieves the desired objective of improving the combustibility of the fuel by breaking down the carbon chains but doing so in the fuel line between the fuel tank and the engine. The then volatile fuel has no access to oxygen until it enters the intake manifold and the combustion chamber where a safe and better combustion results and more cleaner power is generated. The overall beneficial result is that the invention reduces the amount of fuel needed to create the same amount of power safely while substantially reducing the exhaust emissions pollutants. On average this invention can reduce the amount of fuel used by 10 to 25 % while the unwanted exhaust emissions can be reduced by an estimated 35%. The environmental benefits could be greatly enhanced by this product finding its way into the millions of automobiles, other vehicles, combustion engines and heating devices world wide.

Abstract: Methods and apparatus for use in aligning frames in a receiver of a data transmission system include checking one or more bit positions associated with a received data stream to determine a number of bits in the bit positions, respectively, that match a predetermined bit pattern. The number for a bit position is compared to a first threshold value and a second threshold value. A bit position is identified as being associated with a false framing pattern or mimic when the number is not less than the first threshold value. A  bit position is identified as a potential framing bit position or possible framing bit position when the number is not less than the second threshold value. The first threshold value is changed when a bit position is identified as a potential framing bit position and another bit position is identified as being associated with a false framing pattern. For example, the first threshold value may be increased by a given value for every frame that a bit position is identified as a potential framing bit position and another bit position is identified as being associated with a false framing pattern. The given value may be a value of one, a value less than one, or a value greater than one. Frame alignment is declared when a bit position is identified as a potential framing bit position and no other bit position is identified as being associated with a false framing pattern.
