fabric reaches the desired condition a conductivity sensor senses the moisture content of the fabric within the drying zone a sensing circuit electrically connected to the sensor generates a voltage level proportional to the moisture condition sensed the microcomputer reads the voltage level at spaced intervals in time and generates a valid wet signal whenever a given consecutive number of readings indicate a wet condition of the fabric within the drying zone a counter within the microcomputer counts pulses from a source of timing signals and is repeatedly terminated and restarted whenever a valid wet signal is generated the fabric drying operation is terminated upon the accumulation of a preselected count in the counter such that the termination coincides with an optimum dryness condition application_number US 27013081 A description in fig1 there is generally shown an automatic dryer 10 having a cabinet 12 and a control console 14 with controls 16 thereon the controls 16 are generally shown as touch control switches however the controls may be of any number of types commonly known in the art the controls provide fabric selection automatic dry timed dry air and touch up drying cycles a range of selections are available in the automatic and timed dry cycles a front 18 of the cabinet 12 has door 20 which provides access to the interior of the dryer 10 including a rotatable drum 22 provided in a rear stationary bulk head 24 at the rear of the drum 22 there is an air inlet aperture 26 with a perforate cover plate 27 across the aperture 26 and an air outlet aperture 28 formed by perforations 25 in the bulkhead 24 through which air is circulated by a blower or.
