Abstract: The present invention relates in general to the provision of system, method and apparatus for providing temporary low voltage power and is useful for providing power for a Power-over-Ethernet (PoE) powered lighting network. The present invention is useful in a building under construction. Advantageously, the inventive technology includes mobile apparatus that is transportable, thus allowing the apparatus to be transported onto a site, used, and transported from a site. Furthermore, the inventive technology beneficially includes equipment for providing conditioned air space within the apparatus.

Abstract: A detection system for detecting darts which have missed the target in an electronically secored dart game is comprised of first audio sensor circuitry located proximate to the dart board target for detecting sounds created when a dart strikes either the dart board target or the housing in the vicinity of the target and generating an electrical signal upon the detection of such sounds. A second audio sensor circuit located remote from the target is employed for detecting sounds that simulate the sounds created when a dart strikes either the target or the housing in the vicinity of the target and for generating an electrical signal upon the detection of such simulated sounds. The outputs from the audio sensor circuitry are compared and an output comparison signal is generated only when a signal is received from the first audio sensor circuit in the absence of a signal from the second audio sensor circuit.
