Abstract: A folding bicycle trailer that converts between a bicycle trailer mode, a stroller mode, and a folded mode. The trailer has a frame having a first and second side frame assemblies, and a floor assembly. Each side frame assembly has a front wheel and a rear wheel. The front wheels are removed from the frame in the bicycle trailer mode, and are connected to the frame in the stroller and folded modes. A connection arm removably connects to a bicycle in bicycle trailer mode. The connection arm is removable in the stroller and folded modes, but can be connected to the trailer in a second position in those modes. The trailer has a removable push bar for stroller mode. The first and second side frame assemblies remain vertical but move closer to one another in the folded mode.

Abstract: A method, apparatus, and system for compensating for lamp lumen depreciation. The method includes operating the lamp under rated wattage for a period towards the first part of operating life of the lamp. Operating wattage is increased at one or more later times. Energy savings are realized. The increases also restore at least some light lost by lamp lumen depreciation. The apparatus uses a timer to track operating time of the lamp. A few wattage changes made at spaced apart times can be made in a number of ways, including changing capacitance to the lamp, or using different taps on the lamp ballast.

This can be used to check alignment of individual fixture, or can be used to check alignment of an array of fixtures, if the array has a known reference correlation to the fixture with the marking or indicia.

Abstract: A high intensity discharge (HID) light fixture includes a reflector frame which supports an independent high reflectivity reflecting surface. The reflector frame supports a glass lens with anti-reflective coatings on its surfaces and a visor or extension that also supports an independent high reflectivity reflecting surface. The high reflectivity reflecting surface has various sections that adjust portions of the beam created by the fixture to better place light on a target area. The reflector frame is attachable to a lamp cone. An adjustable knuckle attaches between to a cross arm on a pole and the lamp cone. An HID lamp, when mounted in the lamp cone, has its arc tube substantially surrounded by the high reflectivity reflecting surfaces of the reflector frame and visor. A lamp positioning mechanism automatically adjusts orientation of the arc lamp over a range of pivot angles for the lamp cone relative the knuckle.
