Abstract: A system and method of guiding an aircraft is disclosed. The aircraft includes at least one non-rigidly attached sensor for providing a signal indicative of the angular rate of turn of the aircraft. The signal includes an oscillation component and an angular rate of turn component. A filter receives the signal from the sensor and attempts to remove the oscillation component found in the signal. A guidance system provides a commanded turn rate signal. A stability augmentation system receives the filtered angular rate of turn signal and the commanded turn rate signal and processes those signals to provide an actuator command signal. The actuator command signal can best be used to control an air vehicle activation device. The method involves receiving at least one signal indicative of an angular rate of turn of the aircraft from the sensor not rigidly suspended from an aircraft , wherein the signal includes an oscillation component and an angular rate of turn component. The signal is filtered to attenuate the oscillation component while a command a turn rate signal is received. Finally, the filtered signal and the commanded turn rate signal are processed to determine an actuator command signal.

Abstract: The present invention is related to benzothiophen-2-carbonylguanidine derivatives, a preparation method thereof, and pharmaceutical compositions containing the same. The derivatives have potent inhibitory effect on the sodium/hydrogen exchanger NHE-I, improve the functional recovery of ischemia/reperfusion-induced heart injury in isolated ischemic heart models, and significantly reduce the myocardiac infarct size in in vivo ischemic animal models, thereby showing excellent cardioprotective effects. Also, the derivatives are protective of both neuronal cells and the brain as proven by their protective effects on neuronal cells from necrosis and apoptosis and by their ability to significantly reduce cerebral infarct sizes in in vivo ischemic brain models. The derivatives can be effectively used for the prevention and treatment of ischemic heart diseases such as myocardiac infarction, arrhythmia, angina pectoris and the like, and cerebrovascular diseases such as cerebral stroke and be used as cardioprotective agents to the patients undergoing reperfusion therapy including chemicals such as thrombolytic agents, or surgery such as coronary artery bypass and percutaneous transluminal coronary angioplasty.

Patent CA-2618343-A1 (CA)
Inventor: ZHANG QIN
IPC: H04B15/00
Filed: 1999-12-08
Abstract: Interference and/or nonlinear distortions are reduced in a signal communicated from a transmitter to a receiver. To reduce interference, the transmitter is momentarily disrupted, during which time the receiver analyzes interference on the communication path to determine the frequency of at least one peak thereof. Information is communicated from the receiver to the transmitter identifying the frequencies of the interference peaks. Based on this information, the transmitter pre-distorts the signal to accentuate the signal magnitude at the identified frequencies. The pre-distorted signal is then communicated to the receiver, where it is filtered to attenuate the signal magnitude at the identified frequencies. An adaptive scheme periodically determines the interference peak frequencies. For nonlinear distortion cancellation (e.g., CSO/CTB), there is no need to disrupt the transmitter since the frequencies of the distortion are already known. Pre-distortion at the transmitter and filtering at the receiver are performed at the known, fixed frequencies.
