A semiconductor integrated circuit has one or more integral nitride-type sensors. When a portable device receives the request signal in an arrival range of the request signals, the portable device generates a response signal responsive to the request signal. The instruction processing circuit executes instructions of a native instruction set, and the programmable logic is configured to dynamically translate input instructions to translated instructions of the native instruction set. However, if the push pad is jammed in the projected position, the buffer spring is compressed to permit relative movement between the solenoid latch retractor and the manual latch retraction mechanism. Sufficient empty files are included to enable a user to readily locate the collections, and metadata comprising keywords derived from the path of each media clip are associated with each of the media clips to facilitate subsequent searching for the files. A signal point generating apparatus generates a first and second symbols to be transmitted by first and second antennas, respectively.
