Abstract: A swingable solar electric heater comprises an electric heater structure including a head swing element, a heating element, a timer, a base, and a safety dump switch. The head swing element is used to swing back and forth to perform radiant heating within a fixed angle, the timer is connected to the heating element, and the safety dump switch is used to turn off the heating element when the tilt angle of the base exceeds a limit. A current capture device captures the image data of the scene where the electric heater structure is located to obtain and output the corresponding current scene image. An early warning control device is used to extract each pixel value of each pixel in the current scene image, to calculate the standard deviation in the current scene image, and to send a blockage warning signal when the standard deviation exceeds a limit.

Abstract: An automatic switching device is described to switch on an electric heater based on a user wearing a down jacket and switch off the electric heater based on the user not wearing a down jacket. The automatic switching is based on an image collection unit collecting an image of the user, and an image processing unit processing the image to determine if down jacket is in the image. The image collection unit may be adjusted to a position so that it may collect the image between a shoulder and a waist of the user. The adjustment of the position is based on a measured distance between the image collection unit and a floor by an ultrasonic transducer. Since the velocity of sound in air varies with the ambient temperature, a temperature unit is utilized to detect the ambient temperature so that an accurate velocity of sound may be retrieved from a table.
