Abstract
A sensor provides a status signal indicating a condition of an operating system to the operating system's control system. The sensor has an inherent variable quantity such as resistance whose magnitude indicates the operating system status. The control system includes a user-operable switch which when actuated signals the microprocessor to determine the approximate value of the sensor's variable quantity. The magnitude of the variable quantity is then indicated by a signal comprising one or more beeps of sound or flashes of light. The number of beeps or flashes indicates the approximate present magnitude of the sensor's variable quantity. In a preferred embodiment, the control system comprises a microprocessor programmed to control the operating system and to perform most of the functions of the invention.
