A load control system may include control devices for controlling electrical loads. The control devices may include load control devices, such as a lighting device for controlling an amount of power provided to a lighting load, and input devices, such as a remote control device configured to transmit digital messages comprising lighting control instructions for controlling the lighting load via the lighting device. The remote control device may communicate with the lighting device via an intermediary device, such as a hub device. The remote control device may detect a user interface event, such as a button press or a rotation of the remote control device. The remote control device or the hub device may determine whether to transmit digital messages to as unicast messages or multicast messages based on the type of user interface event detected.

An architectural covering is presented having a rotatable drive element having a guide structure and a plurality of idler attachment elements and a drive element positioned over the rotatable drive element. The rotatable drive element is connected to a wall, ceiling or other structure by brackets. In one arrangement a drive shaft having at least one bearing is then attached to the brackets such that the rotatable drive elements rotate upon the bearings. This arrangement provides an efficient, simple and convenient manner of attaching a rotatable drive element to brackets for mounting.

An embodiment of the present invention provides a roller shade actuation device for actuating a winding drum with an outer surface mounted with an end of a shade body. Opposite ends of the winding drum are rotatably mounted to corresponding frames with the help of pivots. The roller shade actuation device is mounted between one of the frames and the winding drum. The roller shade actuation device includes a middle shaft rotatably mounted to an inner sidewall of the frame, and a plane scroll spring mounted outside the middle shaft and axially parallel to the middle shaft. The middle shaft is connected to a pivot of a corresponding end of the winding drum through shaft connection. An outer end of a reed of the plane scroll spring is fixed to an outer surface of the middle shaft.

A method is provided for controlling a networked information apparatus that includes a touch panel display. An electric shutter device is controlled over the network to open and close a shutter remotely. A processor of the information apparatus causes display of an operation icon on a display screen of the information apparatus, and the operation icon causes an operation screen for the electric shutter device to be displayed. When a swipe operation is sensed on the operation screen, a movement control command is output for moving the shutter in a swipe direction of the swipe operation, in which positional information indicating an end position in a vertical direction of the shutter of the electric shutter device is received. State information representing the end position of an end portion of the shutter is displayed in a region corresponding to the shutter image in accordance with the received positional information.

A radiographic inspection device and a method of inspecting an object are provided. The radiographic inspection device includes: a support frame, where an inspection space applicable to inspect an object is formed within the support frame, and the inspection space has an entrance and an exit which are connecting to an outside; a transfer channel applicable to carry the object to move through the inspection space; a first shielding curtain and a second shielding curtain respectively mounted at the entrance and the exit; and a driving mechanism mounted on the support frame and configured to drive at least one of the first shielding curtain and the second shielding curtain to move, in response to the object getting close to or moving away from at least one of the entrance and the exit, so as to open or close the at least one of the entrance or the exit.

A driving mechanism for curtain cord winding reels includes a driving module, and first and second transition shafts mounted to two sides of the driving module. The driving module includes a base, a power member assembled in the base, and a middle shaft connected to the power member and mounted to two sides of the base. Two ends of the middle shaft extend out of the sides of the base and form a first shaft hole and a first axis. The first and second transition shafts are mounted to the ends of the middle shaft. An end of the first transition shaft connected to the middle shaft forms a second axis. An end of the second transition shaft connected to the middle shaft defines a second shaft hole. Cross sections of the first and second shaft holes, the first and second axes are matched with one another, and are non-circular.
