Abstract:
1. A method of flushing a toilet, comprising the steps of: providing a sanitary, user-activated, water-saving, motion-sensing flushing device comprising: sensing the object within the first detection area of the first motion sensor coupled to the controller circuit having the sensor detection and trigger sub-circuit and the oscillator timer operatively coupled to the first motion sensor, and simultaneously or within a predetermined time period; sensing the object within the second detection area of the second motion sensor coupled to the controller circuit having the sensor detection and trigger sub-circuit operatively coupled to the second motion sensor; sensing light with the light sensor thereupon cause the first branch of the sensor detection and trigger sub-circuit to be toggled TRUE; sensing if the object is first detected within the defined volume of the infrared sensor thereupon cause the second branch of the sensor detection and trigger sub-circuit to be toggled TRUE; activating the flush mechanism of the toilet system coupled to the controller circuit upon the sensing of the object within the first detection area of the first motion sensor and the second detection area of the second motion sensor simultaneously or within the predetermined time period, wherein the sensor detection and trigger sub-circuit operable to be triggered if and only if the object is first detected within the defined volume of one of the first motion sensor or second motion sensor and then detected within the defined volume of the other of the first motion sensor or second motion sensor simultaneously or within a predetermined time period, said time period being programmed in code executable by the controller circuit and determined by the oscillator timer integral to or coupled to the controller circuit; and activating the flush mechanism coupled to the controller circuit if both branches of the sensor detection and trigger sub-circuit are toggled TRUE.
