摘要: A control system includes a rate-damping loop that uses a calculated angle-of-attack error to non-linearly scale a rate-feedback signal so that at lower angle-of-attack (AOA) error values, an acceleration feedback term plays a greater role in pitch compensation, while at greater angle-of-attack error values, a rate-feedback term plays a greater role in the pitch compensation. In some embodiments, a control system and method of controlling an angle-of-attack of a moving body are provided. A signal representing an angle-of-attack error is non-linearly combined with a signal representing a rate-of-change of an estimated angle-of-attack to generate a non-linear rate-damping signal. The non-linear rate-damping signal is subtracted from the signal representing the angle-of-attack error to generate a signal to control one or more elements of the moving body.

摘要: Two capacitors and at least one inductor are used to create an alternating magnetic field for use in electric motors. Charge leaving one capacitor passes through the inductor, creating a magnetic field, and is captured by the second capacitor. Energy is added to the second capacitor which is then discharged through the inductor to the first capacitor, creating a magnetic field of opposite polarity as that created by the first discharge.

摘要: A processing vessel for isolating microvessel endothelial cells from liposuctioned fat tissues includes a fat-receiving basket defined by polyester screen material. Fat tissue removed from a patient by liposuction is received into the basket and is rinsed and digested with an enzymatic solution. The freed microvessel endothelial cells from the fat tissues are separated from the fat cells, and from blood cells and other materials which may be present in the basket by centrifuging. A bottom chamber of the processing vessel is configured to define a "pellet" of isolated endothelial cells which may be removed from the processing vessel for deposition on the inner lumenal surface of a synthetic graft which the fat-donor patient is to receive.
