Title: Gas flow enhancer for combustion engines
Inventor: CUMMINGS CRAIG D
IPC: F01D1/36
Filed: 2005-03-07
Abstract: A gas flow enhancer for a combustion engine includes a housing, configured to receive an inlet flow of gas at an inlet pressure, and enclosing an expansion chamber. Disposed within the expansion chamber are a set of inner vanes and outer vanes, and a flow separator. The outer vanes are disposed outside the flow separator and produce an outer helical flow of the gas. The inner vanes are disposed within the flow separator and produce an inner helical flow of the gas, the inner helical flow having a higher velocity and lower pressure than the outer helical flow. The outer helical flow and inner helical flow are recombined at an outlet of the expansion chamber so as to produce an outlet laminar flow profile having a lower average pressure than the inlet pressure.

Title: Technique for compensation of transmit leakage in radar receiver
Inventor: ROSEN ROBERT A
IPC: G01S7/03
Filed: 2006-05-18
Abstract: A radar system (500) radiates a radar transmit signal, has a radar signal receiver (503) and a canceller (505) for canceling leakage of the transmit signal into the radar signal receiver (503). The canceller (505) comprises a digital waveform generator (528) for generating a first digital signal converted to an analog waveform. The analog waveform is amplified after a fixed delay (534) to generate a first cancellation signal input into a circulator (504). The circulator combines the first cancellation signal with the leakage to generate a first corrected signal. A summer (507) combines the first corrected signal from the circulator with a second cancellation signal to generate a second corrected signal. The second cancellation signal is generated by a digital cancellation filter (526). The digital cancellation filter (526) has as an input the first digital signal from the digital waveform generator (528). The digital cancellation filter (526) is controlled using weight adjustments computed by an adaptive weight processor (518). The adaptive weight processor (518) samples the second corrected signal and computes the weight adjustments to optimize the second cancellation signal.
