    摘要： The torque sensor has a body. A first gastight chamber is defined at least partly by the body. A pressure sensor is connected with the gastight chamber for measuring the pressure in the gastight chamber. A pressure to torque converter is connected to the pressure sensor. The gastight chamber is arranged to change its volume by deformation of the body when the body is subjected to a torque wherein the volume change causes a change of pressure of the enclosed gas in the gastight chamber.

    摘要： 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.

    摘要： A system and method for uplink channel estimation for a software defined radio is disclosed. The method comprises dividing an allocated bandwidth for a received signal on the uplink channel into N segments. The uplink channel estimation is processed for each of the N segments as a separate process. The uplink channel estimation includes pre-processing each of the N segments of the received signal; Wiener filtering the pre-processed segments of the received signal in the frequency domain; and Wiener filtering each of the frequency filtered segments in the time domain to determine a channel estimate for each of the N segments for use in equalizing the received signal.
