Abstract
Abstract A storage medium carries information representing the period of time during which a device is to be interrupted. A first portion of the information indicates that the device is to be interrupted, and a second portion of the information indicates the time period during which the device is to remain interrupted. A first digital signal is generated in response to the first portion of the stored information, and the device is interrupted in response to the first digital signal. A second digital signal is generated in response to the first digital signal and the second portion of the stored information, and a series of clock pulses is generated in response to the second digital signal. A preselected number of the clock pulses are counted, and a third digital signal is generated to indicate the completion of the count. The device is started when the third digital signal is generated. The device is interrupted for a preselected time period determined by the pulse repetition frequency of the clock pulses.
