A hinge structure with locking feature is connected to a first body of an electronic device through a support frame. A saturation region is identified, where a color model value of the pixels in the saturation region is above an upper saturation threshold or below a lower saturation threshold. The detecting RF sensor wirelessly transmits the trigger signal to the non-detecting RF sensor. The first and second layers have different doping properties than the first and second vertical Hall effect regions and insulate the first and second vertical Hall effect regions from a bulk of the semiconductor substrate by at least one reverse-biased p-n junction per vertical Hall effect region during an operation of the vertical Hall sensor. Additionally, by gaining control over the wireless device asset the advertisers or advertisement providers are assured that their advertisements will be executed for the duration of the control period.
