Abstract: A control system may include a direct-current (DC) power bus for charging (e.g., trickle charging) internal energy storage elements in control devices of the control system. For example, the control devices may be motorized window treatments configured to adjust a position of a covering material to control the amount of daylight entering a space. The system may include a DC power supply that may generate a DC voltage on the DC power bus. For example, the DC power bus may extend from the DC power supply around the perimeter of a floor of the building and may be connected to all of the motorized window treatments on the floor (e.g., in a daisy-chain configuration). Wiring the DC power bus in such a manner may dramatically reduce the installation labor and wiring costs of an installation, as well as decreasing the chance of a miswire.

Abstract: The present invention is to remedy the cumbersome and messy operation in obtaining a quick shoe shine individually by providing a cylindrical brush. The cylindrical brush is utilized by attaching it to the motor operated screwdriver. The brush has a shape of a cylindrical body with the flat top and bottom. The cylindrical body and the flat top have bristles on them, but the bottom has shaft extending out to be attached to the motorized screwdriver. The bristles on the top portion of the cylindrical body are designed to be used as a polish applicator to the shoe. To the top portion of the cylindrical brush, there is a covering wall having a smaller cylindrical shape which is inserted into the body of the brush from the top with handle extended out onto the surface of the side controlling the covering wall. Also provided is a top brush lid instead of the covering wall to fit over the brush on the top.
