  • Publication number: 20090207078
    Abstract: Method, apparatus, associated computer programs, and signals for channel identification in Multiple-Input Multiple-Output (MIMO) communications systems, and in particular wireless communications systems. The channel derivation method uses steering of mutually orthogonal beamformers at the transmitter end to allow direct identification, whether by selection or mathematical computation, of the channel matrix and hence the preferred transmit beam orientations.

  • Patent number: 7012556
    Abstract: An adaptive signal processing system (800) comprises a plurality of receiving elements (802a–n), a plurality of analogue to digital converters (ADC's) (806a–n) and a digital signal processor (808). Each of the receiving elements (802a–n) is arranged to receive an incoming signal and has an ADC (806a–n) connected thereto. Each ADC *(806a–n) is arranged to convert a first portion of respective incoming signal into a digital form at a sampling rate less than the temporal Nyquist rate of the incoming signal. The signal processing (808) means is arranged to calculate complex weighting coefficients to be applied to a second portion of the incoming signal using the digitized first portion of the incoming signals. A method of calculating complex weighting coefficients is also described.

  • Publication number: 20050112418
    Abstract: An electric power generation system has elements that improve the cold start capability and freeze tolerance of a constituent fuel cell stack cooperate to reduce the amount of water remaining within the passages of the stack. The system includes a purge system that is connectable to the oxidant supply, fuel supply and/or coolant passages upstream of the stack. When the stack is shut down, the stack is disconnected from an external circuit, and purge fluid is transmitted by the purge system through the stack before the stack falls below the freezing point of water. In systems where fuel and/or oxidant streams are humidified prior to entry into the stack, a humidifier bypass system may be provided in place of the purge system. The humidifier bypass system transmits reactant fluid to the stack in fluid isolation from the humidifier, so that the inlet reactant streams are unhumidified.

  • Publication number: 20040231530
    Abstract: A method for embossing expanded graphite sheet material comprises removing at least a portion of the gas from within the material by exposing the material to a pressure less than atmospheric pressure, and then embossing the material. The pressure to which the material is exposed is preferably no greater than about 400 torr. An apparatus for embossing expanded graphite sheet material at a pressure less than atmospheric pressure comprises: an embossing device, a compression device adapted to urge the embossing device against the material, an embossing chamber comprising the at least one embossing device and adapted to receive the material and to be substantially gas-tight at least when the embossing device is urged against the material by the pressing device, and an evacuation device for reducing the pressure within the embossing chamber.
