A book, mainly used by children and students, consists of a book and a speech circuit. The arrangement of this histamine detection method ensures the good color development in a visible region and thus enables easy and quick detection of histamine. The operational efficiency of the tool is improved by creating oscillating forces which vibrate the tool to achieve a desired result, e. Such a SAW sensor chip can includes a plurality of metal electrodes located on the same surface of the plastic substrate as the SAW sensor chip. The method includes creating a netlist from a user defined circuit configuration file, configuring logic resources on the mask-programmed device produce basic logic elements, and generating a custom interconnect based on the netlist that interconnects the configured logic resources to produce the desired logic design.
