In some examples, an optic that includes silicone and is at least 5 inches in diameter is coupled to the fixture housing, and the light fixture is compliant with standard UL-844. In various examples, a top cap assembly is coupled to the fixture housing natively or as a retrofit kit. The top cap assembly includes a top cap and an interface ring, and allows for the light fixture to be attached to an existing top cap.

Abstract: A light fixture includes a light engine comprising at least one light emitting diode (LED), the light engine comprising a front surface and a rear surface. The element includes an electronics housing that is configured to house a plurality of electronic components. The electronics housing is coupled at a first end with the rear surface of the light engine.

Abstract: In one arrangement, a luminaire, for example a luminaire for outdoor lighting, includes a main portion, a pivot member, a swivel member, and a light head. The pivot member and swivel member cooperate to allow the light head to be positioned in any of a number of rotational positions about a first axis and in any of a number of rotational positions about a second axis. The first axis may be vertical, and the second axis may be horizontal.

Abstract: Methods, systems, and devices for portable load balancing and source optimization are described herein. One portable load balancing and source optimization system, includes one or more electric generators that supply three phase electrical power, at least one sensor to sense whether the three phases have become unbalanced beyond a threshold amount, a set of contactors that enable the contacts of the three phases to be changed to adjust the balance of the three phases, and a controller to determine which reversible contactors of the set of contactors to change to adjust that balance of the three phases based on information from the sensor.

Abstract: A plurality of orbiting solar generators stay in constant touch. They can be congregated rapidly in space at any desired secret location. Once congregated selected members of the group focus their energy to a death star. This death star could be a newly launched ICBM with a giant capacitor and a means to connect this capacitor to the selected members of the group of orbiting solar generators. A laser generator uses this giant capacitor energy to project a non-nuclear laser death ray to a target. The target could be a city, a ship or a satellite. In the event of an asteroid approaching earth, this system could destroy an asteroid. In peacetime, the orbiting solar generators may supply electric power to an earth based power grid or other space vehicles.

Abstract: A plurality of orbiting solar generators stay in constant touch. They can be congregated rapidly in space at any desired secret location. Once congregated they all discharge their energy to a death star. This death star could be a newly launched ICBM. A laser generator uses this newly acquired energy on the death star to project a non-nuclear laser ray to a target. The target could be a city, a ship or a satellite. In the event of an asteroid approaching earth, this system could destroy an asteroid. In peacetime the orbiting solar generators could supply electric power to an earth based power grid.

Abstract: Aspects provide photo-control receptacles having contact terminals via which control signals can be communicated. In one aspect, a photo-control receptacle is provided. The photo-control receptacle includes an interface having a neutral conductor and a line voltage conductor. Each of the neutral conductor and the line voltage conductor can form a first electrical connection for providing power to a photo-control via alternating current. The photo-control receptacle also includes one or more additional contact conductors adjacent to the interface. The one or more additional contact conductors can form a second electrical connection for providing control signals to the photo-control.

Abstract: A dozen or more orbiting solar generators stay in constant touch. They can be congregated rapidly in space at any desired secret location. Once congregated they all focus their energy to a death star. This death star is a newly launched ICBM with a microwave or laser collector. A laser generator uses this huge energy to project a non-nuclear death ray to a target. The target could be a city, a ship or a satellite. In the event of an asteroid approaching earth, this system could destroy an asteroid. In peacetime the orbiting solar generators supply electric power to an earth based power grid.

Abstract: A valve keeper verification tool is provided. The tool may include: an elongated body having two ends; an axial hole in one end of the body dimensioned to fit over a valve stem; and structure surrounding the hole dimensioned to contact at least one keeper of a retainer for an engine valve, wherein the tool is angled near the hole between about 10 and about 25 degrees. A method of checking to ensure a valve retaining keeper is in place may also be provided. The method may include: inserting a valve stem into a hole in a valve keeper verification tool; moving the valve keeper verification tool against a keeper; and applying a force against the keeper.

Abstract: A method and apparatus for cooling swimming pool water includes diverting a stream of swimming pool water to a distribution header. The distribution header includes a plurality of dispersing apertures for converting the stream of swimming pool water into a plurality of smaller streams. Positioned immediately beneath the distribution header is a fill medium through which the smaller streams of water pass where they are atomized into smaller droplets. An electric fan is positioned above the distribution header for forcing ambient air through the fill medium to invoke evaporative cooling of the atomized water. The resulting evaporatively cooled water is collected in a reservoir and returned to a swimming pool.

Abstract: A method of holding a billet of material (70) to a machining table (106) includes determining a first set of outer dimensions of a component (72) to be machined. The billet of material (70) is selected in response to the first set of outer dimensions to have a second set of outer dimensions. Dimensions of the second set of outer dimensions are approximately equal to or greater than corresponding dimensions of the first set of outer dimensions. Multiple tabs (76) are attached to the billet of material (70). The tabs (76) are rigidly fixed to the machining table (106). A machining system (50) includes a controller (52) that determines a first set of outer dimensions of a component (72) to be machined. A tab-forming mechanism (54) generates multiple tabs (76) that are configured to be rigidly fixed to a machining table (106).
