Abstract: Automatic flushing, lid raising and seat raising arrangements for toilets include a tank top having optical sensors integral therewith so that standard flush tanks and tops may be used with only the tops being slightly altered to accommodate the optical sensors. The flushing arrangement is readily mountable on standard overflow pipes and provides automatic flushing while also allowing manual flushing. The lid and seat raising and lowering actuators are arranged in a single unit readily attachable to a standard toilet bowl using substantially standard lids and seats.

Abstract: An automatic flushing system for a tank-type toilet. The automatic flushing system includes one or more infrared transmitters that transmit an infrared signal to a sensing area directly in front of a toilet bowl of the toilet. The presence of a user in the sensing area is detected by the system from a reflection of the transmitted infrared beam off of the user. Detection of the user in the sensing area for a predetermined minimal period of time causes an automatic courtesy flush. Once the user has left the sensing area, the automatic flushing system will provide a main flush. The automatic flushing system includes a lift arm operated by a flush motor positioned within the toilet tank. Activation of the motor causes the lift arm to push against a flush arm in the toilet tank to flush the toilet. The lift arm is positioned beneath the flush arm to allow for manual flushing.

Abstract: An automatic toilet seat device which will cause a toilet seat to be either raised or lowered at the push of a single button and further, will automatically lower the toilet seat after the flush action of the toilet. A first switch associated with the device will, when activated, cause the toilet seat to be raised by an electric motor. Once the toilet user has flushed the toilet, a float switch associated with a tank of the toilet will cause the motor to lower the toilet seat. The control circuit controlling the automatic toilet seat device is microprocessor controlled and includes an over-current detection circuit. The over-current detection circuit will detect over-current in the motor when the seat is completely raised or lowered such that the microprocessor will stop the motor from turning.
