Abstract:
A hybrid thermoelectric-ejector active cooling system having an increased Coefficient of Performance (COP) when compared to typical thermoelectric cooling modules. A thermoelectric cooling module is integrated with an ejector cooling device so that heat from the thermoelectric cooling module is rejected to a high temperature evaporator of the ejector cooling device. This provides for a total COP greater than the sum of the COPs of the thermoelectric cooling module and ejector cooling device individually. For example, given 1 unit input power into the thermoelectric cooling module, the heat received by the cold side of the thermoelectric cooling module would be COPTEC×1; and the energy rejected by the hot side of the thermoelectric cooling module and to drive the ejector cooling device would be COPTEC+1. Thus, the cooling received by the low temperature evaporator of the ejector cooling device is COPEJ×(COPTEC+1); and therefore total COPTE-Ej-AC is COPEj+COPTEC+COPEj×COPTEC. In addition, the hybrid thermoelectric ejector active cooling system will be able to operate at higher temperature differentials than standalone thermoelectric cooling devices.

Abstract:
A method of preparing a carbon nanotube/polymer composite material is provided. The method includes (a) providing a carbon nanotube-based film and a pre-polymer solution; (b) placing the carbon nanotube-based film at a bottom of a container, and pouring the pre-polymer solution in the container; and (c) polymerizing the pre-polymer solution and simultaneously integrating the pre-polymer solution with the carbon nanotube-based film. As such, a carbon nanotube/polymer composite material, including the polymer-impregnated nanotube layer and an upper polymer layer, is obtained. A multi-layer composite can be produced by essentially repeating this process, using the upper polymer layer as the base layer for the formation of the next layer set thereon.

A method of remote capture with user interface providing separate inside- and outside-light-box modes is provided, wherein when the user selects the inside-light-box mode together with an automatic mode to take a photograph, it is the photographic parameters, which are obtained experimentally for various cameras under given light sources, but not the photographic parameters, which are automatically generated by the light sensor of the camera, that are utilized to control the camera. Via the inside-light-box mode together with the automatic mode, an image in good qualities is acquired.

Abstract:
A diverter spout has a drain pipe, a connecting sleeve, an offset shaft, a resilient element between the drain pipe and the offset shaft, a pole for manual operation, a supporting sleeve and an envelope. At least a leakproof rubber ring is mounted around the offset shaft. Due to interferential friction between the leakproof rings and the connecting sleeve or the supporting sleeve and water pressure, a blocking portion of the offset shaft controls the water to flow only through a spout. In normal state, the resilient element overcomes interferential friction between the leakproof rings and the connecting sleeve or the supporting sleeve and controls the water to flow only through a drain opening of the drainpipe. Therefore, water diverts reliably without leakage.
Abstract:
A variable frequency decoding apparatus operable in a portable audio device that can improve the power management is disclosed. The above apparatus has a decoder and a clock generator that provides the system clock for the decoder. When a bit stream representing audio compressed data is received, the decoder simultaneously provides the audio information embedded in the audio compressed data such as the bit rate and the sampling frequency of the data frame to the clock generator, and then the clock generator adjusts the clock signals; which are used by the decoder to restore to the original PCM format, to match the audio information embedded in the data frame. This audio signal compression technique can prevent possible output delay and reduce power consumption as compared with the conventional way that used a fixed sys clock.
