An image recording apparatus includes a sheet transport path, a first unit, and a second unit. In the apparatus, a tool body and a tool lid are connected together by a hinge means in a clam-shell configuration. The first circuit blocks are connected between the first power bus and the second power bus, and the second circuit blocks are connected between the second power bus and ground. Properly positioned within the container, a lure requires relatively little space and is secured to prevent tangling with other baits. A system for improving the performance of an internal combustion engine according to the invention includes a source or energy operative to generate singlet delta oxygen from molecular oxygen, and apparatus for mixing the SDO with fuel prior to, or during, combustion. The first circuit may be configured to generate a plurality of symbols and a plurality of decision values both in response to detecting an encoded codeword.
