The invention is directed to a composite material, especially a biomedical device, e. The computer system periodically determines utilization information for the computer system and adjusts the performance state according to the utilization information. The inferring operation includes identifying implicit references to antecedent elements. Filtering the data may be performed blockwise. The computation of fuel consumption rate does not require an injection pulse signal, so the fuel consumption rate can be precisely computed even for a vehicle which does not have an injection pulse signal such as a non-EGI vehicle or a diesel engine vehicle. The processing comprises steps of receiving radio frames in a receiver of the user equipment, identifying the transport block sizes of the radio frame in the user equipment, and determining whether the received radio frame includes transport blocks that are not directed to the user equipment.
