An illumination device for a firearm may include a housing supporting multiple lamps. A switch actuator of the device is rotationally coupled to a rear end of the housing. A cam is coupled to the switch actuator, such that the cam rotates with the actuator, the cam having a first end including a magnet and a second end having a shaped cam surface configured to interface with a cam follower. The actuator and the cam are biased toward a neutral position. Selective rotation of the cam causes a magnet of the cam to operate one or more magnetic switches. The cam is transitionable between a plurality of discrete positions, e.g., including a pair of toggle positions in the first rotational direction from the neutral position, and a pair of momentary positions disposed on the cam in the second rotational direction from the neutral position.

A container apparatus can include a container and an insert assembly. The insert assembly can include four elongate members. The four elongate members can include light emitting devices for illuminating the interior of the container and/or temperature altering elements for cooling and/or heating the interior of the container. The container can have a rectangular base and a rectangular sidewall extending upwardly from the base. The sidewall can define four corners of the container, and four elongate recesses can be formed in the sidewall proximate the four corners of the sidewall to receive the elongate light members. The recesses can be sized and shaped to conform to the elongate insert members so that the insert members can be releasably retained within the elongate recesses.

The present invention relates to a top toolbox to provide additional storage on top of a toolbox without eliminating the workbench of the toolbox. The top toolbox is comprised of a cabinet, a frame guide, and lifting means to adjust the cabinet from a resting position in which the cabinet covers the frame guide to a raised position allowing access under the cabinet within the perimeter of the frame guide.

A system is described for an enhanced bow piece of a stringed musical instrument. The enhancement includes a visual display element attached to the bow. The appearance of the display changes in response to bow motion, bow position, and one or more user-supplied inputs (e.g. buttons). The system can be entirely self-contained and used as a normal instrument bow, providing a light-up/responsive effect while the user plays their instrument in an otherwise normal way. There is some capability for multiple self-contained units to be locally synchronized, providing group-based visualizations. Alternatively, these devices can be monitored and controlled by an external control system.

An illuminated cornhole platform comprising a top portion, at least two side portions, a front portion, a hole portion, at least one leg portion, and a back portion. The cornhole platform is illuminated by illumination sources arranged along a majority of an outer perimeter of the rectangular platform, with the plurality of illumination sources outlining the outer perimeter of the rectangular platform.

An improved container for storing liquids includes a main body. The main body includes a front surface, a rear surface, a left side surface, a right side surface, a top surface, a base surface, and plurality of cylindrical surfaces. The top surface includes an aperture adapted to allow liquids to pass therethrough. The front surface, the rear surface, the left side surface, the right side surface, the top surface, and the base surface form an interior volume adapted to retain liquids therein. The plurality of cylindrical surfaces extend between the left side surface and the right side surface.

Internally illuminable playing cards are disclosed. The disclosed playing cards may include a polymeric body, at least one light-emitting diode (LED) at least partially inside of the polymeric body, a battery (or a slot in the polymeric body for receiving a battery) for providing power to the at least one LED, and a switch at least partially inside the polymeric body and operatively connected to the at least one LED to facilitate turning the at least one LED on and off. As can be understood based on this disclosure, the internally illuminable playing cards can be used for flourishing and cardistry techniques, in a manner similar to the way typical paper playing cards are used for such techniques.

Apparatus and method provide underwater lighting to illuminate a site within a body of water in which underwater lighting apparatus is immersed during a lighting cycle. A housing is constructed of a heat-conductive material and LED arrays are affixed to the housing, within a sealed chamber, to conduct heat from the LED arrays to the housing such that heat generated by the LED arrays during the lighting cycle will be conducted directly to the housing and dissipated by the housing to the surrounding body of water. Light provided by the LED arrays is passed through corresponding lens members located for directing light in different directions. At the same time, fouling by marine organisms is resisted.

A method and system provide accent lighting at a bank of gaming machines. A plurality of LED panels are provided to be assembled in a number of different configurations for a series of LED panels. An electronic controller coupled to communicate through said data communication interface with the series of LED panels. The electronic controller is programmed to transmit signals to LED drivers of the LED panels, receive a loop-back signal transmitted from a final one of the LED panels, based on timing of said received loop-back signal automatically identify a configuration of the series of LED panels from said number of possible configurations, and transmit commands for activating the LED drivers of the LED panels based on the identified configuration.

A blade-height optimization indicator for a table saw determines based on the rotational position of one or more blade guards of the table saw as they are displaced by a workpiece being cut whether the blade-height of the table saw is optimized relative to the thickness of the workpiece and provides a visual GO/NO-GO indication depending on whether the blade-height is determined to be optimized.
