Abstract: A tooling system is disclosed for wood or metal working including a working element, and a work piece engagement surface at least partially surrounding, positioned adjacent to, or positioned proximate to, the working element, the work piece feedable toward the working element or the working element feedable across the work piece when the work piece is positioned against or supported by the work piece engagement surface; wherein the work piece engagement surface includes a low friction and/or non-stick coating. The workpiece engagement surface may be roughened up such that it has an average surface roughness (RA) of between about 1 micrometer and about 4 micrometers to facilitate its adhesion with the low friction coating while providing a low friction coating with a low coefficient of kinetic friction.

Abstract: A band saw is disclosed that includes a frame, a guide wheel, and a blade disposed around the guide wheel. A guide wheel chassis can be movably disposed on the frame, the guide wheel rotatably disposed on the guide wheel chassis. The band saw can include a blade tension adjustment assembly including a tensioning motor, wherein operation of the tensioning motor produces movement of the guide wheel chassis and the guide wheel relative to the frame to adjust the tension of the blade. A tension gauge can be positioned to determine a tension in the blade, and a controller can be communicated with the tensioning motor and the tension gauge, the controller operable to receive tension data from the tension gauge and control operation of the tensioning motor based on the tension data to control the tension of the blade.

Abstract: The described embodiments relate to systems, methods, and apparatuses for establishing a network of sensor-responsive lighting units using an interface of each lighting unit. The interface of each lighting unit can include a channel selector switch for selecting a channel to which each lighting unit will be connected. In this way, the creation of a network can be created by placing the lighting units proximate to each other and selecting the same channel at the interface at each lighting unit. The lighting units can include sensors for detecting events occurring at each lighting unit, and information related to the detected events can be shared among other lighting units in the network. Each lighting unit can operate in different operating modes such as a testing mode for testing communications channels and a manual mode for allowing a lighting unit to operate independently of the information shared over the network.

Abstract: A movable barrier operator mounts to a ceiling or a wall of a garage. The movable barrier operator includes an operator housing with a motor configured to open and close a movable barrier. The movable barrier operator also includes an LED light source mounted to the housing, a light cover, and a light distributing element. The light cover has several side surfaces that surround or covers the light source. The light distributing element mounts relative to the light source and is configured to scatter light projected by the LED light source so that some of the scattered light is directed toward one or more of the side surfaces of the light cover.

Abstract: An electrical fixture includes an electrical fixture housing having a mounting surface, an electrical connector disposed on the mounting surface, and an electrical fixture support. A corresponding cover plate or mounting strap includes an electrical connector configured to electrically connect to hot and neutral lines from a junction box and the corresponding electrical connector disposed on the mounting surface of the electrical fixture. An electrical fixture ground connection separate from the fixture electrical connector electrically connects to an electrical ground from the junction box.

Abstract: A light guide projects light in an asymmetric pattern. The light guide is installable with respect to a light emitting diode (“LED”) and extends along an optic axis. The light guide projects light with respect to first and second parallel projection planes that are parallel to and disposed on opposite sides of an optic axis. The light guide includes an optic body that extends along the optic axis. The light guide has a proximal end surface configured to receive light from an LED. The light guide also has a distal end surface configured to distribute light emitted by the light emitting diode. The distal end surface can take on various shapes, patterns, and configurations to distribute light asymmetrically with respect to the first and second parallel projection planes.

Abstract: A transmitter apparatus is provided that includes an actuator and a transmitter with a housing and wireless transmission circuitry. The actuator is mounted to a structural element of a building and is at least partially exposed and accessible to a user. The housing is arranged and configured to extend at least partially into an opening in the structural element of the building. The transmission circuitry is arranged and configured to receive the actuations from the actuator and responsively transmit radio frequency (RF) signals to a remotely situated appliance via the antenna.

Abstract: A cover-attachment assembly works in conjunction with an audio-annunciator housing that is configured to operationally mount to a wall. This audio-annunciator housing can have one or more arcuately-shaped tracks and one or more snap interfaces. The cover-attachment assembly comprises at least one arcuately-shaped guide surface that is shaped, sized, and positioned to fit within the arcuately-shaped track when pivotally attaching the cover-attachment assembly to the audio-annunciator housing. The snap interface, in turn, is shaped, sized, and positioned to lockingly mate with the audio-annunciator housing snap interface to hold the cover-attachment assembly in an installed position with respect to the audio-annunciator housing.
