Abstract: A method of locating a golf ball is disclosed. The method includes providing a golf ball which includes a radiation source of a particular radiation type that is continuously emanating radiation, providing a radiation sensor capable of discerning and sensing the emanated radiation and providing an electronic signal corresponding to the sensed radiation indicative of radiation intensity, continuously mapping location of the radiation sensor by generating location coordinates, correlating the electronic signal to the location coordinates generating a correlation data, and determining location of the golf ball from the correlation data.

Abstract: A dustpan is disclosed. The dustpan include a debris receptacle coupled to the grip, having a debris collection surface and a bottom surface, and a roller mechanism, wherein the roller mechanism includes a roller with an adhesive surface, a biasing member, and a handle to apply a force coupled to the grip, wherein application of force to the handle moves the roller from i) a non-contact position, above the bottom surface of the debris receptacle, to ii) a contact position, configured to be one of below the bottom surface of the debris receptacle or ground level, and wherein once the force is released the biasing member returns the roller to the non-contact position.
