Abstract: A light fixture having a housing and a handle formed integrally in the housing. In some embodiments, the handle is positioned at a center of gravity of the light fixture so as to facilitate carrying of the light fixture and/or to reduce stress on the carrier's hand.

Abstract: A tank data storing and monitoring system and method have an RFID tag coupled to and associated with a tank. The RFID tag has a unique identity specified by a unique identifier stored electronically on the RFID tag. Also included are an internet-accessing computer and database. The database stores data unique to the tank having the RFID tag coupled thereto. An RFID reader coupled to the computer is used to read only the unique identifier of the RFID tag. The computer accesses the data unique to the tank stored on the database using the unique identifier.

Abstract: A tank support system includes a hollow open-top container having a contiguous sidewall region and a bottom region coupled to the sidewall region. A loop antenna is coupled to a portion of the container's sidewall region. A tuning circuit coupled to the loop antenna provides for adjustment of the loop antenna's electrical impedance. A radio frequency identification (RFID) reader is coupled to the tuning circuit.

Abstract: A spray gun comprises a first block and a mixing feature. The first block comprises a first sealing face, and a second sealing face. A first fluid passageway terminates in the first sealing face, while a second fluid passageway terminates in the second sealing face. The mixing feature comprises a third sealing face, a fourth sealing face, and a mixture chamber. The third sealing face is adjacent to the first sealing face and includes a first conduit in fluid communication with the first fluid passageway. The fourth sealing face is adjacent to the second sealing face and includes a second conduit in fluid communication with the second fluid passageway. The mixture chamber is in fluid communication with the first and second conduits and defines a longitudinal axis. The first, second, third, and fourth sealing faces are each oriented obliquely relative to the longitudinal axis of the mixing chamber.
