Abstract: In an embodiment, a USB interface includes a transformer, a primary winding of the transformer, and a first switch in series between a first and a second node, a secondary winding of the transformer and a component in series between a third and a fourth node, the fourth node configured to be set a first reference potential, a second switch connected between the third node and a first terminal, the first terminal configured to provide an output voltage of the USB interface; wherein the component is configured to avoid a current circulation in the secondary winding when the first switch is closed and a control circuit configured to compare a first voltage of an interconnection node between the secondary winding and the component to a first threshold and compare the first voltage to a second threshold when the first voltage is, in absolute values, above the first threshold.

Abstract: A system to sanitize a surface includes an emitter. The emitter of the system to sanitize the surface includes: a light source configured to generate light at a sanitizing wavelength; a receiver configured to receive a wireless signal; and a processing circuit for the emitter configured to turn the light source on, turn the light source off, and adjust an intensity of light generated by the light source depending on the wireless signal. The system to sanitize the surface further includes a sensor. The sensor of the system to sanitize the surface includes: a photoelectric transducer configured to convert light at the sanitizing wavelength to a current; and a processing circuit for the sensor powered by the current and in communication with a transmitter to transmit the wireless signal, the processing circuit for the sensor being configured to control emission of the wireless signal depending on a power level supplied by the current.
