Title: Maximizing power and spectral efficiencies for layered and conventional modulations
Inventor: CHEN ERNEST C
IPC: H04L/
Filed: 2003-10-16
Abstract: Methods and apparatuses for maximizing power and spectral efficiencies in a wireless communication system are disclosed. The invention is particularly useful for layered modulation applications because power levels for such applications are relatively high. A layered modulation signal comprises an upper and a lower layer signal that interfere with each other within the same frequency band such that the upper layer signal can be demodulated directly from the layered modulation signal, and the lower layer signal can be demodulated after subtracting the first layer signal from the layered modulation signal. The invention applies one or more of the following four signal schemes in a communication signal including varying the symbol rate (rather than the code rate), reducing or eliminating the guard band, reducing excess signal bandwidth and employing layered modulation within the guard band of the legacy signal.

Title: Method for reducing the oil content of potato chips
Inventor: DESAI PRAVIN MAGANLAL
IPC: A23L5/20
Filed: 2008-07-02
Abstract: A method is disclosed which reduces the oil content of a potato chip. The method teaches that a steeper, faster temperature drop upon initial introduction of the potato slice to the fryer, followed by a longer period of exposure to lower temperatures before increasing to standard frying temperatures, reduces oil content of a potato chip. The invention further discloses a pre-treatment method which involves submerging the potatoes in a hot water bath which results in decreased oil content. Additionally, the invention discloses a post-treatment method involving subjecting the potato chip to superheated steam that further reduces oil content. The two pre and post-treatment methods, combined with the primary temperature scheme method for reducing oil content, yield a potato chip with significantly reduced oil content.

Patent CA-2719513-A1 (CA)
Inventor: BENMOUYAL GABRIEL
IPC: G01R35/00
Filed: 2009-03-31
Abstract: A system and method for acquiring phasors outside of the frequency tracking range for power protective relays. As the frequency of a power system varies from the rated frequency, phasors calculated from such samples include errors. A frequency tracking range is used to sample the signal waveform at a rate corresponding to the frequency when the frequency is within the frequency tracking range. When the frequency is outside of the frequency tracking range, the signal waveform is sampled at a rate corresponding with the maximum or minimum of the frequency tracking range depending on whether the frequency exceeds or falls below the frequency tracking range. The difference between the frequency and the minimum or maximum of the frequency tracking range is used to correct the measured phasors to result in accurate phasors.

Abstract: An energy recovery interior heating system has a modified mechanical or electrical drive isolation system for vehicles such as trucks. This permits a standard air conditioning compressor pump to be driven from multiple power inputs thereby providing any hybrid or non-hybrid vehicle with continuous engine-on heating and/or air conditioning, limited time engine-off heating and air conditioning and two types of engine-off air conditioning temperature modulation. Another combination of the heating and air conditioning systems would permit the continuation of heating and cooling on hybrid vehicles when they are stationary and their traction batteries are fully charged and the vehicle is operating only on the electric motors for traction or work load power. This invention also provides internal combustion engine-off heating and A/C  on these types of vehicles. Another embodiment uses the drive isolation system to integrate auxiliary power unit (APU) functions as part of the traction engine of over the road trucks.
