Abstract: A hand tool including a first head having at least one working surface, a second head having at least one working surface, and a handle having a first end and a second end, where the first head is coupled to the first end of the handle and the second head is coupled to the second end of the handle. The utility tool also includes a core coupled to the first head and the second head and extending through the handle.

Abstract: A charging device is provided. The charging device includes an input interface configured to receive electrical power from a power source and charge a removable energy storage device using the electrical power from the power source. The power source may be a solar panel. The charging device may include multiple input interfaces configured to receive electrical power at different voltages. The charging device may include an output interface configured to provide electrical power to an electrical device connected to the output interface, and the circuit may be configured to provide electrical power to the output interface from at least one of the removable energy storage device and the input interface.

Abstract: An electronic sheet cutting machine includes a housing to which a drive roller is coupled for moving a sheet to be cut in a first direction and a cutter assembly coupled to the housing and moveable in a second direction that is perpendicular to the first direction. A user interface is incorporated into the housing for allowing a user to select via the user interface at least one shape to be cut by the cutter assembly wherein controlled movement of the drive roller and the cutter assembly causes a shape to be cut in the sheet.

Abstract: A lighting apparatus includes a body portion, a conduit coupled to the body portion, and one or more illumination components coupled to the body portion, where the one or more illumination components are in electrical communication with the conduit. A lighting apparatus kit is also disclosed. A daisy-chained lighting apparatus assembly is also disclosed.

Abstract: A battery pack power system includes a plurality of modular, portable, battery modules having various capacities that can be mixed and matched with one another to suit any of a wide variety applications or provide the desired power to any of a wide variety of loads at off-grid locations. The individual battery modules are stackable or otherwise nestable or connectable with one another to permit multiple users to each separately transport a module to a desired location and then combine the modules to assemble the battery power pack. One or more flexible connectors are provided for electrically chaining the assembled battery modules to one another and that permit only one-way, correct-orientation connection of the battery modules to one another, and have no exposed electrically conductive surfaces. An inverter module is connectable to any one of the battery modules, and operates to deliver 110 VAC in a first mode and 220 VAC in a second mode to provide electrical power to a wide variety of electrical loads.

Abstract: A blade housing for an electronic cutting apparatus includes an outer housing having a distal end, an inner housing coupled to the inner housing and longitudinally selectively adjustable relative thereto and a blade rotatably coupled to the inner housing with a sharpened distal end. Adjustment of the inner housing relative to the outer housing adjusts an amount of the blade that protrudes from the distal end of the inner housing.

Abstract: A modular solar panel system includes solar panels mechanically and electrically interconnectable to create a modular solar panel array, and an electrical connection module on each panel, the module having an input connection and an output connection for electrically interconnecting the panels in the solar panel array. A peripheral frame member is disposed about each panel, and includes a first set of receptacles arranged on a back face, and a second set of receptacles arranged along an outside edge. The second set of receptacles are arranged along each side so that the receptacles on one panel align with the receptacles on another panel when placed adjacent one another in a generally planar edge-to-edge manner.
