摘要： A system and method to establish the lock point of a digital synchronous circuit (e.g., a DLL) at the center of or close to the center of its delay line is disclosed. The synchronous circuit is configured to selectively use either a reference clock or its inverted version as the clock signal input to the delay line based on a relationship among the phases of the reference clock, the inverted reference clock, and a feedback clock may be used during determination of the phase relationship. The selective use of the opposite phase of the reference clock for the input of the delay line results in centralization of the lock point for most cases as well as improvement in the tuning range and the time to establish the initial lock, without requiring an additional delay line.

摘要： A system for dynamic optimization of gain and contrast in ultrasound imaging includes an image processor module programmed to dynamically estimate a correction profile in real-time and apply the correction profile to adjust a gain and contrast of image frame data sets. The image processor module is programmed to identify tissue and background regions in an image frame data set, determine an image intensity for each of the tissue and background regions, and formulate a gain profile based on the image intensity of the tissue region to compensate the gain variation of an image. The image processor module is further programmed to calculate an image contrast metric based on the image intensity of the tissue and background regions, and modify a gray map of the image frame data set based on the image contrast metric to adjust the contrast of an image displayed on the display system.

摘要： Delay-locked loops, signal locking methods and devices incorporating delay-locked loops are described. A delay-locked loop includes a forward loop path, a feedback loop path, and a phase detector. A test clock signal is temporarily switched to traverse the forward loop path and the feedback loop path. The phase detector is coupled to both the forward and feedback loop path circuits and is configured to periodically adjust responsive to a calculated loop delay of the test clock signal. The phase detector is thereafter able to stabilize at an improved rate.
