摘要： A system and method for range dependent weighting in ultrasound imaging. The system includes a transducer array, a data acquisition system, and an imaging processor. The transducer array receives a first ultrasound beam having a first focal depth. The data acquisition system receives a first ultrasound imaging signal from the array. The first signal includes first image data based on at least the first ultrasound beam. The imaging processor combines a first data contribution from the first image data with at least second image data from a second ultrasound imaging signal to create a spatially compounded image. The first data contribution is based on at least the focal depth of the first beam.

摘要： Disclosed is a system including a substrate having a first side and a second side and a layer of photoacoustic material disposed on the first side of the substrate. The layer of photoacoustic material is configured to generate a directional ultrasound wave in response to a laser beam impinging on the layer. A conduit may be coupled to the housing and have an opening adjacent to the layer of photoacoustic material; the directional ultrasound wave may be directed through fluid that is contained in the conduct to generate a liquid jet in a liquid.

摘要： A driving circuit for controlling power of a light-emitting diode (LED) light source includes a transformer, a switch controller, and a dimming controller. The transformer has a primary winding that receives input power from an AC/DC converter and a secondary winding that provides output power to the LED light source. The switch controller coupled between an optical coupler and the primary winding receives a feedback signal indicative of a target level of a current flowing through the LED light source from the optical coupler, and controls input power to the primary winding according to the feedback signal. The dimming controller coupled to the secondary winding receives a switch monitoring signal indicative of an operation of a power switch coupled between an AC power source and the AC/DC converter, and regulates the output power by adjusting the feedback signal according to the switch monitoring signal.

摘要： Methods of synchronizing signals are provided. Specifically, a detector is provided in the digital phase detector to detect certain failure conditions that may result from clock skew and duty cycle distortion. If the condition is detected, an adjusted signal is generated and the adjusted signal is synchronized with the reference signal. By using the generated signal to provide a lock if certain conditions arise, adjustment errors resulting from duty cycle distortion and clock skew can be minimized.
