摘要:
An apparatus, method, and system for switch control of power to light sources, particularly high power consumption light sources that may experience lumen depreciation, such that the power level to a light source may be increased or decreased as desired. Methods of switching utilizing robust mechanical components such as solenoids, coupled with accurate and rapid electronic control components such as microprocessors, may be combined with a combinational approach to capacitance changes to comprise a flexible method of power control to a light source or plurality of light sources. Power to a light source may be adjusted such that the amount of energy consumed and the quantity of light output may be adjusted, compensation may be made for lumen depreciation and other losses that occur during operational life of the light source, to maintain constant or near-constant light output, or otherwise.

Disclosed herein are apparatus, methods, and systems for grounding outdoor light poles, as well as other structures, which may be exposed to lightning or other adverse electrical effects and may require a low impedance path to ground. Inventive aspects include a combination of apparatus integral to the pole or other structure and installation considerations whereby the ease of installation, reduction of onsite installation error, and reduction of impedance may be tailored to each installation. An apparatus can include a pre-installed earth grounding electrode at the lower end of the pole or structure to be inserted into the earth. A method can include installing an earth grounding electrode to/on/in a lower end of a pole or structure prior to insertion into the earth.

A drainage system for a fenestration assembly is located in a rough opening of a structure. The drainage system includes a moisture barrier located between at least a bottom of the fenestration assembly and a bottom inner surface of the rough opening. The moisture barrier includes a vertical portion extending generally vertically downward below the rough opening on an external side of the structure. A channel assembly is located generally below the rough opening. The channel assembly includes at least one channel having a channel entrance proximate the bottom inner surface of the rough opening and a discharge opening direct toward a drainage area. The channel includes an effective cross-sectional area adapted to siphon water located on the moisture barrier to the drainage area.

A window assembly having a window frame and at least one primary sash mounted in the window frame. The primary sash has a plurality of sash members forming a primary sash perimeter and a first glazing panel mounted in the primary sash perimeter. At least one secondary sash is pivotally attached directly to the primary sash perimeter along an interior surface thereof so that the secondary sash is rotatably movable between a closed position and an open position relative to the primary sash. The secondary sash has a plurality of secondary sash members forming a secondary sash structure and a second glazing panel mounted in the secondary sash perimeter. An air chamber is located between the primary sash and the secondary sash that is substantially closed to the interior of the building structure. At least one accessory channel is locating along at least one side of the secondary sash members.

An invertible side insertion trap is designed to be inserted into an opening in an electrical box and to accommodate at least two different sizes of cable or wire depending on an orientation of the trap. The trap includes a base, a first arm and a second arm. The first arm extends from the base and includes a first mating portion for mating with a first side of the opening in the electrical box. The second arm extends from the base. The arms create a passage having a first width for permitting insertion of a first cable or wire size between the arms when the trap is oriented in a first orientation with the first mating portion aligned with the first side of the opening. The passage has a second width for permitting insertion of a second cable or wire size between the arms when the trap is oriented in a second direction with the first mating portion aligned with a second side of the opening.

A lighting fixture includes a first open end, a second end, a movable dividing plate positioned between the first and second ends, and a release mechanism. The dividing plate defines a light compartment extending from the open end to the plate and a wiring compartment extending from the plate to the second end. The release mechanism is designed to release the plate to move the plate to permit access to the wiring compartment from the first end. The lighting fixture may stacked with other lighting fixtures of the same type, with the second end of one fixture inserted into the first open end of an adjacent fixture.
摘要:
A self-sealing window with a flexible gasket that extends around the entire perimeter of closure assemblies and a method of installing such closure assemblies in a rough opening. A sealing member is attached continuously around an entire perimeter of the closure assembly to form a water impermeable seal between the sealing member and the closure assembly. The closure assembly is inserted into the rough opening. Accurate positioning of the closure assembly in the rough opening is verified. The closure assembly is secured in the rough opening. The sealing member is engaged with an exterior surface of the structure proximate the rough opening. A foam material is delivered into at least a portion of a space between perimeter edge surfaces of the closure assembly and inner surfaces of the rough opening.

An actuation system for use with an adjustable covering for a fenestration product. The actuation system coupled to an operator for controlling adjustment of extension and contraction of the covering. The actuation system including a drive system configured to decouple the actuation system from the operator during a potentially damaging event, such as slack in a lift cord during extension of the covering. The drive system later recoupling the actuation system and operator while maintaining rotational registration between multiple components of the actuation system.
