A computer-readable recording medium stores a program that causes a computer capable of accessing a multicore processor equipped with volatile memories and a plurality of cores accessing the volatile memories, to execute a data restoration process. The hollow bar comprises a slide bar 3 for the hook 2 of the shower head or a grip bar 15 for a user. More particularly, the accumulation of results of a correlation of a received signal with a generated frequency and a generated code having numerous time offsets is temporarily stopped when the control signal is activated and resumes operation when the control signal is deactivated. The method may further comprise separating the laminated body into first and second portions separated by a separation plane including the scribed groove by applying load to the second major surface of the laminated body. A cord can be identified within the region based on occurrence of one or more events within the region of the signal. A controller, including an angular acceleration signal generator, receives the first accelerometer signal and the second accelerometer signal and generates an angular acceleration signal from a difference in amplitudes between the first accelerometer signal and the second accelerometer signal.
