Abstract: A compact animal waste collector and method thereof is provided. The collector includes a planar base having a first side and a second side. A plurality of walls is affixed perpendicularly to the base. A substantially planar first cover is hinged to at least one of the plurality of walls, the first cover forming an interior compartment proximate to the first side of the base and movable between at least a first position and a second position. A bag is removably located within the collector and lining the interior compartment, the bag having an opening edge inverted about an exterior of the collector. A storage compartment is formed on the second side of the base and enclosable by the plurality of walls and a substantially planar second cover hinged to at least one of the plurality of walls. The storage compartment may house a replacement bag.

Abstract: A system and method for sensing proximity of an object includes a signal generator, which generates a plurality of signals. A transducer is in communication with the signal generator to receive the plurality of signals from the signal generator. The transducer is capable of transforming a plurality of signals from the signal generator into a plurality of ultrasonic waves. The plurality of ultrasonic waves includes a first ultrasonic wave and a second ultrasonic wave, wherein the first ultrasonic wave and the second ultrasonic wave are formed out of phase. The plurality of ultrasonic waves are directed toward and reflected by the object. The transducer receives the plurality of ultrasonic waves reflected by the object, which become a plurality of received ultrasonic waves. An analog to digital converter is in communication with the transducer. The received plurality of ultrasonic waves reflected by the object is communicated to the analog to digital converter by the transducer.
