20090310640MOCVD GROWTH TECHNIQUE FOR PLANAR SEMIPOLAR (Al, In, Ga, B)N BASED LIGHT EMITTING DIODES - A III-nitride optoelectronic device comprising a light emitting diode (LED) or laser diode with a peak emission wavelength longer than 500 nm. The III-nitride device has a dislocation density, originating from interfaces between an indium containing well layer and barrier layers, less than 9×1012-17-2009
20110062415ANISOTROPIC STRAIN CONTROL IN SEMIPOLAR NITRIDE QUANTUM WELLS BY PARTIALLY OR FULLY RELAXED ALUMINUM INDIUM GALLIUM NITRIDE LAYERS WITH MISFIT DISLOCATIONS - An epitaxial structure for a III-Nitride based optical device, comprising an active layer with anisotropic strain on an underlying layer, where a lattice constant and strain in the underlying layer are partially or fully relaxed in at least one direction due to a presence of misfit dislocations, so that the anisotropic strain in the active layer is modulated by the underlying layer.03-17-2011
20110064103SEMIPOLAR NITRIDE-BASED DEVICES ON PARTIALLY OR FULLY RELAXED ALLOYS WITH MISFIT DISLOCATIONS AT THE HETEROINTERFACE - A dislocation-free high quality template with relaxed lattice constant, fabricated by spatially restricting misfit dislocation(s) around heterointerfaces. This can be used as a template layer for high In composition devices. Specifically, the present invention prepares high quality InGaN templates (In composition is around 5-10%), and can grow much higher In-composition InGaN quantum wells (QWs) (or multi quantum wells (MQWs)) on these templates than would otherwise be possible.03-17-2011

20100022885SWITCHING DC CONVERTING DEVICE AND PORTABLE SYSTEM FOR ULTRASONIC MEDICAL IMAGING AND DIAGNOSING AND METHOD THEREOF - A switching DC converting device includes a switching DC converter and a synchronous clock circuit. The synchronous clock circuit is used to provide a wobbling synchronous clock input for the switching DC converter, and the central frequency of the wobbling synchronous clock avoids the operating frequency of a circuit powered by the switching DC converter.01-28-2010
20100262012METHOD FOR A MEDICAL DIAGNOSTIC ULTRASOUND SYSTEM TO SAVE POWER AND THE MEDICAL DIAGNOSTIC ULTRASOUND SYSTEM - To save power used by a medical diagnostic ultrasound system, a detection device is disposed on the probe side of the medical diagnostic ultrasound system to detect whether the probe is being used, and to generate a corresponding control signal according to the detected signal. A transmitting and receiving circuit disposed on the probe side transmits the signal to a transmitting and receiving circuit disposed on the host side to control a working mode of an ultrasound transmitting and receiving circuit within the host.10-14-2010

20090259129Resonance Ultrasonic Transducer - The present invention provides a resonance ultrasonic transducer. The resonance ultrasonic transducer comprises an ultrasound source for transmitting ultrasound, and a reflecting unit disposed opposite to the ultrasound source. The ultrasound source and the reflecting unit Constitute a resonance cavity. The reflecting unit can also act as an ultrasound source. A specific distribution of the acoustic field may be formed in the resonance cavity by matching the transmitting acoustic field of one ultrasonic transducer with the reflecting acoustic field of the other ultrasonic transducer. This resonance ultrasonic transducer can be widely used in ultrasonic diagnosis device, ultrasonic therapy device and ultrasonic detection devices and carries out effective focusing and controlling of an ultrasonic fled.10-15-2009
