Patent number: 7012556Abstract: 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.Type: GrantFiled: October 7, 2002Date of Patent: March 14, 2006Assignee: Qinetiq LimitedInventors: Michael Dean, Paul Nicholas Fletcher

Publication number: 20050112418Abstract: 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.Type: ApplicationFiled: April 26, 2004Publication date: May 26, 2005Inventors: Joy Roberts, Jean St-Pierre, Marian van der Geest, Abderrahmane Atbi, Nicholas Fletcher
