Abstract: Methods of supporting DALI protocol between DALI controllers and devices over an intermediate communication protocol are disclosed. We will describe an implementation of the invention using the mesh wireless network prescribed by IEEE 802.15.4 as an intermediate protocol where it's long latency and highly variable delay characteristics poses a significant challenge to maintain adherence with the DALI specification. For practitioners skilled in the art it is obvious that the invention is also applicable to many other communication mediums and protocols, including wired networking such as Ethernet and Wifi networking such as IEEE 802.11 a/b/g/n. Additionally, the invention is applicable to transport other control protocols where specification limits the duration between forward messages and associated reverse replies.

Abstract: The present invention provides a stroboscopic optical image mapping system comprising a control module, an optical module, and an image acquiring unit. The control unit forms a delayed pulse signal by modulating a first pulse signal having a plurality of pulses with a pulse period, wherein a time interval between two adjacent pulses of the delayed pulse signal has a time difference with respect to the pulse period. The optical module provides an incident light to be projected on an organic object, which has a dye therein and is stimulated by a second pulse signal for generating a sequential action potential. The fluorescence generates from the dye inside the organic object, which corresponds to the intensity of the sequential action potential. The image acquiring unit is actuated to acquire the fluorescent light according to the delayed pulse signal, thereby forming a plurality of fluorescent images.

Abstract: An evaluation system for determination of cardiovascular function parameters using ultrasound images is provided. The evaluation system includes a data reading module, a 2D image generating module, a contour determination module, an active contour module, a geometric center axis computing module, and a function evaluation module. After reading cardiovascular ultrasonographic files with the data reading module, the 2D image generating module displays 2D images. Then, active contours are generated by the contour determination module and the active contour module, so as for the geometric center axis computing module to calculate geometric center axes. Finally, the function evaluation module calculates evaluation parameters according to the geometric center axes. Thus, evaluation parameters can be derived from cardiovascular ultrasound images for clinical diagnosis in the evaluation of cardiovascular functions.

Abstract: An apparatus in a video signal transmission system for measuring cable length and compensating for cable loss is described. A number of pilot signals of different frequencies are compressed into one of the three color signals during the vertical sync periods in a time-division manner. The vertical and horizontal sync signals are compressed into the other two color signals.

A compensation control circuit averages the levels of the multiple pilot signals of different frequencies over a number of vertical sync periods, and generates compensation control signals based on the average level of the pilot signals. The compensation control signals are used to perform video signal compensation.
