The invention relates to an electric housing device having an adjustable span, comprising a main body portion, a winding cord, and a first moving part and a second moving part close to the two ends of the main body portion. The main body portion is provided with a driving device, and the bottom of the main body portion is provided with two parallel slide rails which slide along the length direction of the main body portion. The two slide rails extend towards the first moving part and the second moving part respectively and are fixed to the bottoms of the corresponding moving parts. The main body portion and the first moving part, and the main body portion and the second moving part are respectively provided with through grooves corresponding to the two slide rails, each through groove is located on the outside of the corresponding slide rail, each slide rail is slidably provided with a central running pulley, and the top of each central running pulley extends out from the corresponding through groove. The winding cord revolves around the driving device, the main body portion, the first moving part and the second moving part for one circle and winds around the driving device for several circles. The tops of the central running pulleys are fixed to the winding cord. The device is adjustable in terms of span, widely applicable and light in weight.

The present disclosure relates to a method and a device for adjusting indoor illumination intensity. In the method, a target illumination intensity value is acquired when a target electric appliance is running and the target electric appliance is susceptible to illumination intensity in a room. In the method, a first indoor illumination intensity value in the room is collected, and an indoor illumination intensity adjustment device is controlled according to the first indoor illumination intensity value and the target illumination intensity value. The indoor illumination intensity adjustment device is controlled to change the first indoor illumination intensity value to achieve a second indoor illumination intensity value where the second indoor illumination intensity value conforms to the target illumination intensity value.

A retrofittable curtain apparatus capable of being installed onto existing curtain tracks comprising a curtain and curtain carriers. The apparatus may comprise a pair of latches on either side to facilitate simple installation onto the curtain track by clamping the apparatus to the track. A pair of switches located on either side of the apparatus allows a user to activate the apparatus by tugging on the curtain, pulling it taut over the switch thereby actuating it. The apparatus comprises an internal assembly of efficiently arranged gears and motors that produce a substantially small horizontal form factor, allowing for use with wave fold curtains.

A device for opening and closing a curtain on a rod or rail includes a driven wheel coupled to a motor within a housing. The driven wheel protrudes from the housing in frictional engagement with the rod or rail. The device further includes a suspension assembly including a support member and one or more linkages. The support member is in sliding or rolling contact with the rod or rail. The linkages extend along an independent suspension axis and connect the support member to the housing to suspend the housing from the support member, allowing the device to traverse bumps in the rod or rail. The driven wheel is rotated by the motor to advance the device along the rod or rail for opening and closing the curtain. A curtain opening system may further include one or more sensor targets disposed on the rod or rail, and an encoder and a sensor operatively connected to a controller of the device for auto-calibration of position tracking.
