An implantable hearing assistance system includes a sensor transducer and an electronics unit. The agent resides within the test and measurement instrument and gathers the information when activated. The solar panel receiving structure preferably includes a base member, a first side member coupled to the base member, and a second side member coupled to the base member. The CDR circuit 100 outputs an oscillation clock signal a0 at a clock output terminal TRCK as a recovery clock signal RCK. The second client subsystem includes a microprocessor, software running on the microprocessor for facilitating an escrow arrangement, a camera coupled to the microprocessor, and a display coupled to the microprocessor. Output signals from the mixing circuitry are selectively coupled through a variable delay line to synchronize two clock signals.
