Abstract: A portable energy storage and power supply system includes a first housing member, a second housing member coupled to the first housing member, a gasket coupling the first housing member with the second housing member, a battery, and a connector assembly coupled to the battery. The first housing member and the second housing member define an internal space. The battery is disposed within the internal space and configured to store electrical power. The connector assembly includes a shield having an open end and a closed end, a grommet disposed around an outer surface of the shield, and a cap disposed over the closed end of the shield and coupled to the grommet. The grommet is configured to reduce moisture penetration into the internal space of the first housing member and the second housing member.

Abstract: An energy storage and power supply system includes a body having a first end and an opposing second end, a battery pack disposed within the body, a first connector disposed at the first end of the body and electrically coupled to the battery pack, the first connector including a male connector configured to receive electrical power to charge the battery pack, a second connector disposed at the opposing second end of the body and electrically coupled to the battery pack, the second connector including a female connector configured to provide a power output from the battery pack, and a collar slidably coupled to the opposing second end of the body and movable between an extended position and a retracted position. The collar is configured to engage with and thereby retain an accessory when selectively reoriented into the extended position.

Abstract: A reconfigurable battery pack power system with interchangeable accessories has at least one modular, portable, rechargeable battery module having a first side, the first side having a first contour and a mounting port and a power output port, and at least one accessory module configured to receive power from the battery module. The accessory module has a second side with a second contour that mates with the first contour on the battery module, and has a power coupling connector and a fastener. The accessory module is interchangeably mateable with the battery module with the first and second contours nested together, and with the power output port engaged with the power coupling connector and with the fastener engaged with the mounting port, so that the battery module and the accessory module form a single integrated and substantially rigid structure.

Abstract: Charging devices, modular adapters, and circuits are provided. One charging device including a body including a rechargeable energy storage device and a housing. The housing includes at least one first coupling portion. The charging device further includes a modular adapter including a second coupling portion configured to be mated to the first coupling portion of the housing. When mated to the housing, the modular adapter is configured to be electrically connected to the rechargeable energy storage device. When the modular adapter is mated to the housing, the body and the modular adapter form a single integrated and substantially rigid structure.

Abstract: Given a situation where a projected laser line appears to have terminated or faded as it intersects with a work-surface (e.g., a wall), a fan-out redirecting means is used to capture and redirect energy radiating above and parallel to, or radiating away from the given work-surface area, where the captured energy is from a line projector mounted to the surface. The radiation capturing and redirecting means aims the captured energy at a greater angle towards the work-surface so that the redirected light is thereafter reflected back to a user to give the perception that a line of enhanced intensity or reborn existence is being created on the work-surface or on a reflective overlayer placed against the work-surface. The radiation capturing and redirecting means may include one or both of optically refractive means and optically reflective means (e.g., lens and mirrors) for performing the capturing and/or redirecting functions.

Abstract: A spherically rotatable support for a light image projector has level and/or plumb indicators for leveling or plumbing a central reference frame of its spherical rotation. A projected light image, such as a laser line segment of relatively short length may be successively stepped across a long wall while maintaining its level or plumb condition. A low powered laser or other light source may be used to generate the short-length, line segment in place of a more high powered light source that would otherwise be needed to illuminate the full length of the wall or other such surface.

Abstract: A sensor such as a stud sensor having a capacitor plate coupled with a spring to a head to provide a floating head. In other versions, the sensor has an on-switch coupled between a head and a body of a sensor; a head detachable from a body of the sensor; a marking instrument coupled with a lever to a body of a sensor; and a body having one or more low compression and/or low resistance slider pads.

Abstract: A light emitting module and a modular light emitting system with leveling capability. The system relates to light-based (e.g. lower-based) layout tools of the type used in the construction industry. More specifically, the system relates to a modular light emitting system for projection visible patterns, such as dots, lines, cross-lines and other patterns, on one or more distant surfaces for purposes of alignment, construction, verification and the like.

Abstract: A self-leveling tool for projecting a line of light along a wall or other vertical surface at one of a plurality of predetermined angles. The tool self-aligns to emit a plane of light at one of the predetermined angles (e.g., 0, 90, 180 or 270 degrees), thereby projecting a line on the wall in a desired direction (e.g., right, up, left or down).
