    摘要: A novel transceiver structure is proposed to increase the achievable data rate for ultra wideband transmitted reference (UWB-TR) systems. For every Ns pulse pairs during one symbol transmission, the data pulses are weighted by one of the M-ary orthogonal sequences, thus carrying additional log2 M-bit information. Furthermore, by utilizing a pair of balanced matched filters before the cross correlator, the minimum separation between the reference and data pulses is significantly reduced without causing any inter-pulse interference (IPI), which in turn reduces the minimum required frame length in order to avoid the inter-frame interference (IFI). As a result, the invented TR system can achieve higher data rates than the conventional TR system, while maintaining superior bit-error-rate (BER) performance even with lower transmit power.

    摘要: A brazed plate heat exchanger (30) is provided for transferring heat between a first fluid (32) and a second fluid (34), with the first fluid (32) being pressurized to a relatively high pressure. The heat exchanger includes plate pairs (41), with each pair (41) defining a plurality of flow channels (56) for the first fluid (32). Each of the flow channels (56) has a hydraulic diameter less than 1 mm. Reinforcements (62) are provided between each of the plate pairs (41) and are aligned with inlet and outlet openings (46,48) to define inlet and outlet manifolds (50,52) for the first fluid (32).

    摘要: A refrigeration system includes a multiple stage compressor 10 having at least two stages 12,14 for sequentially compressing the refrigerant together with a gas cooler 21 connected to the compressor 10 for receiving compressed refrigerant from the last stage 14 of the compressor to cool the same. An evaporator 18 is connected to the gas cooler 21 via an expansion device to receive cool refrigerant therefrom and cool the fluid stream passing through the evaporator 18. A return passage connects the evaporator 18 to the first stage 12 of the compressor and an intercooler 26 is connected between the first stage 12 and the last stage 14 of the compressor to cool refrigerant compressed by the first stage 12 and direct the refrigerant cooled thereby to the last stage 14 for further compression. The intercooler 26 and the gas cooler 21 are integrated into a single unit 22 and receive a single cooling heat exchange fluid and the gas cooler 21 has a larger heat transfer surface area than the intercooler 26.
