Devices, systems, and methods for a frame with a slidable segment are disclosed. The slidable segment is slidably mounted within the frame. A first motor is coupled to the slidable segment. The first motor has a first gear affixed to and driven by the first motor. A first gear track may be mounted to a first horizontal member of the frame, wherein teeth of the first gear align with tooth spaces of the first gear track. Rotating the first gear in a first rotational direction causes the first gear to pull the slidable segment in a first linear direction as the first gear walks along the first gear track. Rotating the first gear in a second rotational direction causes the first gear to pull the slidable segment in a second linear direction as the first gear walks along the first gear track.

The invention is a method for intelligent current limiting enabling chaining of electrical appliances. Different embodiments apply to alternating current (AC) appliances, direct current (DC) appliances, and a combination of each. In each embodiment, current limits control the number of appliances that can be connected in thechain. If current limits are exceeded, current-limiting devices cut power to one or more of the appliances. Each appliance in the system has conductors with the capacity to carry a current load at least as large as the overall current limit. Preferably, the appliances in the system are garage appliances that are mounted to an overhead track system in a garage, where electrical outlets are scarce.

A wireless rail system for providing power and control to auxiliary devices on the rail is disclosed. Such a system includes a one or more channels mounted to a structural building component forming a rail. Auxiliary devices on the rail communicate with each other and user devices. Each of the auxiliary devices are addressable either wirelessly or by a parallel bus within the rail. The auxiliary devices are connected and disconnected from the rail by rotating approximately 90 degrees.

An apparatus includes a motor and a drum rotated by the motor to draw in or let out a line from the drum. The drum includes a groove formed in an outer surface thereof to accommodate the line. In certain embodiments, the motor and drum are quickly and easily detachable from a structure by way of a flange and mounting bracket. The flange and mounting bracket have holes which are coaxially aligned. A pin or other fastener is used to join the flange and mounting bracket together.

An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. A cable is incorporated into the line to transport at least one of power and data along the line to an object or device at the end of the line. In certain embodiments, the cable is configured to support all or a portion of the load. In other embodiments, the line includes a load-bearing wire separate from the cable which is configured to support all or a portion of the load.

An apparatus includes a motor and a drum rotated by the motor to draw in or let out a line from the drum. The drum includes a groove formed in an outer surface thereof to accommodate the line. In certain embodiments, a depth of the groove is equal to or greater than a radius of the line. In the same or other embodiments, a passive guide that physically engages and tracks the groove may be used to guide the line into the groove.

An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. The transmission includes at least one stage of gearing to reduce a gear ratio of the motor relative to the drum. A shaft couples the motor to the transmission and a locking mechanism selectively locks the shaft to prevent rotation of the drum. In certain embodiments, a braking mechanism may be provided in addition to the locking mechanism to slow the motor when the motor is not applying torque to the drum. This may slow the motor sufficiently to enable engagement of the locking mechanism.

An apparatus for providing reliable line traction spooling for hoists, winches, and other pulling and/or lifting devices is disclosed. In one embodiment, such an apparatus includes a motor and a drum rotated by the motor to draw in or let out a line from the drum. The drum includes a groove formed in an outer surface thereof to accommodate the line. A roller is provided to place pressure on the line against the drum. A roller consists of at least one indentation or protrusion on an outer surface to assist the drum in spooling the line onto and off of the drum. In certain embodiments, the roller is patterned in order to improve line traction. In other embodiments, a line is compressible in order to improve line traction.
