Abstract:
The present disclosure discloses a method and a device for adjusting indoor brightness and a smart home control system. The method includes: detecting a display device to obtain brightness of the display device; generating indoor brightness based on the brightness of the display device; and adjusting brightness of an indoor lighting device based on the indoor brightness.
Abstract:
There is provided a method for detecting a rotation angle of a remote controller(21) in a television system(30,40) in order to realize a detection for the rotation angle of the remote controller(21) with respect to the television(20), which extends an application prospect of the television system. The television system (30,40) includes a television (20) and a remote controller (21), and the method comprises: collecting(S101), by the remote controller (21), an image of preset infrared sensors on the television (20) and imaging the collected image to a preset plane as a standard image, in a case in which the remote controller(21) does not rotate with respect to the television(20); collecting(S102), by the remote controller(21), an image of the infrared sensors on the television(20) and imaging the collected image to the preset plane again, in a case in which the remote controller(21) rotates with respect to the television(20); and calculating(S103) a rotation angle in a case in which the remote controller(21) rotates with respect to a screen of the television(20) by comparing the image with the standard image. There is further provided a television system(30,40).
Abstract:
Embodiments of the present disclosure disclose a variable resistance and a manufacturing method thereof, and the variable resistance is a variable resistance with continually adjustable resistance value. This variable resistance comprises: an elastic insulation envelope and conductive particles filled in the elastic insulation envelope. The manufacturing method of the variable resistance comprises: filling conductive particles into an elastic insulation envelope with an opening; and sealing the opening of the elastic insulation envelope.
