A system for adjusting the height of fixtures in a dwelling unit, comprising at least one lifter with a base below the floor line of the dwelling and extending through the floor of the dwelling wherein the lifter is adapted to lower the fixture down to or near floor level is also disclosed. A system for rearranging the furniture in a room, comprising: at least one lifter with a base below the floor line of the room and extending through the floor of the room wherein the lifter is adapted to lower the fixture down to or near floor level; at least one lifting device attached to an item of furniture; at least one runner attached to the item of furniture; and at least one vertical channel adapted to interact with the at least one runner as the item of furniture is raised or lowered to or from a space above the room; whereby the furnishing is supported by the connection to the lifting device; and whereby the at least one runner travels along the at least one channel as the item of furniture is raised or lowered is also disclosed.

There is described a shower system that includes a showerhead fixture and a base connected by conduits. The showerhead fixture includes an inlet for receiving pressurized water. A diverter is configured to divert at least a portion of the pressurized water to the base. The showerhead fixture also includes a second inlet fluidly connected to a recirculating showerhead portion with a plurality of showerhead jets for expelling mixed water received from the base. The base is configured to create a reservoir of water on a shower floor and includes a venturi pump capable of using pressurized water from the showerhead fixture to draw in water from the reservoir into the stream of pressurized water. The mixed water is sent from the base to the jets in the showerhead fixture to thereby increase the volume of water expelled from the showerhead.

A device to control rotation is disclosed. The device includes a stationary portion having an internal aperture with a frustoconical inner surface. The device also includes a movable portion having a frustoconical outer surface, adapted to engage the frustoconical inner surface, to stop rotation between the movable portion and the stationary portion when engaged. An input sleeve is included, configured to transmit an applied rotational force to the device, also configured so that, as the input sleeve moves in a first axial direction, the moveable portion engages the stationary portion, and as the input sleeve moves in a second and opposite axial direction, the moveable portion is pushed out of engagement with the stationary portion. The device further includes a one-way rotation governor, non-rotatably attached to the movable portion and non-rotatably attached to a shaft and configured to allow rotation between the movable portion and the shaft in one rotational direction and prevent rotation between the movable portion and the shaft in a second opposite rotational direction.

Systems, devices, and methods for locating an item within an enclosure is described. The method includes affixing a first-tier label to a fixture within the enclosure, identifying a first location of the first-tier label based on at least three distance measurements between the first-tier label and a respective plane of the three orthogonal planar surfaces, identifying a second-tier label in proximity to the first-tier label, wherein the second-tier label is associated with an item, determining a first relative position of the second-tier label with respect to the first location of the first-tier label, and determining a second location of the second-tier label based on the first relative position with respect to the first location and the first location.

A mechanism for opening and closing an overhead door includes a drive loop coupled to the overhead door, a motor with a drive shaft and a drive wheel for driving the drive loop. A one-way bearing couples the drive shaft to the drive wheel, which one-way bearing is configured to transmit torque from the motor to the drive wheel, as the motor rotates the drive shaft in a first rotational direction to raise the overhead door, and configured so that torque is not transmitted to the drive wheel as the motor rotates the drive shaft in a second rotational direction opposite the first rotational direction. As a result, the motor applies torque through the one-way bearing to raise the overhead door and to support the weight of the overhead door while lowering the overhead door.

A trailer is disclosed which includes a first door with a first hinge configured to allow the first door to operate between an open position and a closed position, and a second door on the opposing side of the trailer with a second hinge configured to allow the second door to operate between an open position and a closed position. The trailer also includes a roof and a trailer tongue with a coupling configured to attach to a hitch of a vehicle. Two or more wheels are provided that are extendable from an up position to a down position. In this way, when the wheels are in the down position, the trailer is lifted off the ground. The trailer can thus change between at least three modes, including a first mode for storage, wherein the first door and second door are in the closed position and the wheels are in the up position; a second mode for ingress and egress, wherein at least one of the first door and second door are in the open position; and a third mode for travel, wherein the first door and second door are in the closed position and the wheels are in the down position.

A system for moving cargo is disclosed. The system includes a cart, which, in turn, includes a body with a battery compartment and a platform. The cart also includes wheels and a motor for driving the wheels. A battery is housed in the battery compartment for powering the motor. The system also includes a cargo carrier mounted on the platform. The cargo carrier includes a base, two side walls, and two end walls. At least one end wall or side wall is adapted to be moved between different positions to change the shape and/or size of the compartment.

The invention is a retrofit device for converting a standard switch to a smart switch. The retrofit device taps into an existing switch electrical terminal via one or more sliding arms with electrical contacts. The electrical contacts interface with the terminals, thus providing a control circuit to intervene or interrupt the existing switch function and allow a control system to control the electrical circuit the existing switch serves.

The disclosure provides a device for automatically opening and closing a pair of curtains that includes a rod with a longitudinal hollow space. The device also includes a first and second threaded shaft housed within the hollow space. First and second gears are attached to the first and second threaded shaft, respectively. The first and second gear intermesh, so that, when the first threaded shaft rotates in a first angular direction, the second threaded shaft rotates in an opposite second angular direction. The device also includes first and second threaded nuts, threaded onto the first and second threaded shafts. A motor is provided to rotate the first threaded shaft in the first angular direction and simultaneously rotate the second the shaft in the opposite second angular direction.

Disclosed is a winch. The winch includes a motor. A driveshaft that is coupled to the motor, and the motor rotates the driveshaft. End plates at opposite ends of the driveshaft are configured to support the driveshaft between the end plates, and to allow rotation of the driveshaft. A spool is fixed to the driveshaft such that the motor rotates the spool by rotating the driveshaft. A line is attached to the spool and rotation of the driveshaft causes the spool to wind the line onto the spool or unwind the line from the spool. At least one support member is coupled between the end plates. The at least one support member is generally parallel with and spaced apart from the rail, and the support member is fixed to the end plates such that the support member keeps the end plates and drive shaft in alignment.
