The present invention provides an electret transducer with solar power. The intermediate frequency input circuit includes a pair of input nodes; a pair of output nodes; and resonance circuits, which are coupled between the pair of input nodes and resonate with an intermediate frequency of a selector channel. During parallel processing mode operation, mode control circuitry recognizes and resolves branch instructions to be executed and causes the processor to operate in the serialized mode when necessary to prevent any conflict between the pipelines due to branching. The first contact is movable relative to the second contact to close the switch upon rotation of the handle. The LDSRs also transfer passenger loads exerted on the outer portions of the floorboard to the DS and PS frame struts.
