Abstract: A bulb-type LED lamp having a replaceable light source module includes a lamp head module, a lamp casing module and a light source module. The lamp head module has an electrical-conductive connection portion. One end of the lamp casing module is connected to the lamp head module. The light source module comprises a substrate, a plurality of LEDs electrically connected to the substrate, and a sleeve disposed in the lamp casing module to be electrically connected to the substrate. The sleeve has an electrical-conductive insertion portion assembled with the electrical-conductive connection portion. By this structure, a damaged light source module can be replaced rapidly. A user needs not to by a new whole set lamp so as to save the cost maintenance. Further, a surface thermal contact is generated between the metallic pressing plate and the heat-conducting plate to increase the heat-conducting area and efficiency.

Abstract: Systems and methods for detecting and tracking objects, such as motor vehicles, within video data. The systems and method analyze video data, for example, to count objects, determine object speeds, and track the path of objects without relying on the detection and identification of background data within the captured video data. The detection system uses one or more scan lines to generate a spatio-temporal map. A spatio-temporal map is a time progression of a slice of video data representing a history of pixel data corresponding to a scan line. The detection system detects objects in the video data based on intersections of lines within the spatio-temporal map. Once the detection system has detected an object, the detection system may record the detection for counting purposes, display an indication of the object in association with the video data, determine the speed of the object, etc.

Abstract: The present invention provides a system and device for current measuring, controlling, and heat sinking which includes a positive electrode terminal carrier, a positive electrode output terminal carrier, a negative electrode terminal carrier, and a current control circuit carrier. The system and device is to be installed on a battery with high current capacity. In which the output current flowing through the battery's positive electrode is measured by the current measurement device which is installed in the positive electrode terminal carrier. A reverse current control switch and a forward current control switch are installed in the current control circuit carrier to control the current flowing path and the current flowing in the path. Furthermore the heat generated by the circuit is radiated by the current control circuit carrier.

Abstract: An improved heat-radiating fin set formed by combining a heat pipe and several heat-radiating fins can assemble several fins for heat radiation of an electronic component. The improved heat-radiating fin set can be quickly mass-produced in an automatic way to lower the manufacturing and assembly cost without using any solder material for binding. The improved heat-radiating fin set comprises a heat pipe and several fins. A sleeve hole is disposed in each fin. A flange is formed at the edge of each of the sleeve holes. The fins are tightly sleeved with the heat pipe through the sleeve holes with the flanges of the sleeve holes of the fins touching the outer wall of the heat pipe.
