Abstract: The present invention provides a heat spreading tape including at least one heat spreading layer adapted for heat dissipation and at least one heat insulating layer adhesively attached to the heat spreading layer. Void regions are formed in the at least one heat insulating layer and are adapted for acting as heat transfer barriers in a direction perpendicular to the major surfaces of the heat spreading tape, i.e. the thickness tape.

Abstract: Systems and methods to identify an event(s) representing a discontinuity in the impedance of a transmission line such as a wire cable using time domain reflectrometry (TDR) are presented. According to an exemplary embodiment, multiple layers of digital signal processing techniques are implemented in an algorithm that combats the smearing effect of a wide launch pulses with the reflection due to an event. The algorithm focuses on wavelet decomposition and additional post processing to produce a well-defined signal that allows easy identification of the reflected signal while preserving critical information, such as the location of the event and relative signal strength.

Abstract: The present invention relates to a pogo stick structure, more particularly, a pogo stick comprising a foot-pad housing with handlebars thereof and a support rod; wherein, a foot-pad housing rises at the position of the foot pads and forms a hollow tube creating space for placing a compression spring therein; the installation of the tube helps to stabilize the compression spring while making constrained and released movements, and also reduces great height of the foot pads to the ground which can decrease user's fear in operating the pogo stick; moreover, the external flange of the foot pads is mounted with a plurality of LED flash lights, and under the foot pads installs a controller which switches on/off the LED flash lights and creates sound.

Abstract: A shutter including a casing, two chain transmission mechanisms bilaterally and vertically mounted inside said casing, two linkages suspended from the top rail of the casing on the inside, a set of louvers pivotably connected between the linkages, a power drive controlled to turn the chain transmission mechanisms, and two hook members fastened to the chain transmission mechanisms and moved to carry the linkages and the louvers between the active position and the inactive position, louvers being carried turned between the horizontal position and the vertical position when the linkages are moved to the active position and the chain transmission mechanisms are continuously turned to a certain extent.
