Abstract: A light fixture can include a light housing and a light cartridge. The light cartridge can be configured to releasably and/or electrically connect to a portion of the light housing. In some embodiments, the light cartridge includes a collar movably connected to the cartridge and configured to rotate with respect to the cartridge. Rotation of the collar can facilitate attachment and/or release of the cartridge from the light housing. In some cases, the cartridge includes a releasable driver, one or more lenses, one or more beam reflectors, one or more diffusers, and/or other electrical and optical components.

Abstract: A system operable with a passive anti theft security system having a first coil connected to a passive anti theft controller for transmitting a first signal to a first transponder having a third coil and a first code therein, said first transponder responsive to said signal transmitting said first code to said first coil, the system comprising a second transponder having a second code and a fourth coil with two terminal ends wound about said third coil of said second transponder; and a relay selectively shorting or opening said terminal ends of said fourth coil to selectively enable and disable said second transponder.

Abstract: A remote starting system operable with a passive anti theft security system. The passive anti theft security system includes a first coil connected to a passive anti theft controller, which is used for transmitting a first signal to a first transponder. The first transponder has a third coil and a first code. The first transponder is responsive to the first signal and transmits the first code to the first coil. The remote starting system comprises a second transponder, which has a second code and a fourth coil. The fourth coil has two terminal ends wound about the second transponder. The system further comprises a relay that selectively shorts or opens the terminal ends of the fourth coil so as to selectively enable and disable the second transponder.
