    Abstract: A display includes a display panel and a circuit. The circuit controls the display panel according to at least one control mode such as a pulse width modulation control mode. A method for determining a state of the display includes: acquiring samples from a channel of an ambient light sensor disposed below the display panel; supplying the samples to a processing circuit; detecting, by the processing circuit and based on said samples, whether the display panel is controlled in pulse width modulation; and following detecting the pulse width modulation control mode, calculating by the processing circuit a duty cycle from the samples.

    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.

    Abstract: A device includes comprising first and second printed circuit boards. Walls couple the first and second printed circuit boards to each other and define a first cavity between the first and second printed circuit boards. Electric conductors associated with the walls electrically connect the first and second printed circuit boards. An integrated circuit chip is mounted to a first surface of the first integrated circuit board in the first cavity. The integrated circuit chip is electrically connected to conductive tracks of the first surface of the first printed circuit board. Surface-mounted components are mounted on top of and in contact with conductive tracks of a first surface of the second printed circuit board. The first surfaces of the first and second printed circuit boards are arranged facing towards each other. The first and second printed circuit boards may form rigid components of a flex-rigid type printed circuit board.

    Abstract: An example computer system includes at least two processors, a power supply controller, configuration registers, and a wake-up circuit. The computer system has a deep sleep mode in which the processors are not supplied with power. The power supply controller is configured to detect events of different types to be processed in the processors in the deep sleep mode. The configuration registers are configured to assign the processing to the different processors according to the type of event detected. The wake-up circuit is configured to disable deep sleep mode after an event is detected, and activate, when disabling deep sleep mode, a power supply of one of the at least two processor to which the processing of the detected event has been assigned according to the configuration registers. The activation of the power supply powering on one of the processors, which is configured to process the detected event.
