    Abstract: A magnetic energy harvesting and scavenging circuit includes a first substrate having first and second surfaces and at least one energy harvesting and scavenging coil formed adjacent the first surface. An electromechanical systems device includes a moveable mass extending over the first surface and is displaced relative to the first substrate in three dimensions responsive to an external force applied to the moveable mass. The movable mass includes a magnet support layer and a number of permanent magnet segments attached to the magnet support layer. The permanent magnet segments are magnetically coupled to the at least one energy harvesting and scavenging coil. Energy harvesting and scavenging circuitry is electrically coupled to the at least one energy harvesting and scavenging coil and generates electrical energy due to magnetic flux variation through the at least one energy harvesting and scavenging coil responsive to movement of the moveable mass.

    Abstract: A method of manufacturing a magnetic-field sensor includes forming an insulating layer on a first surface of a substrate. First and second magnetoresistors are formed at different above the first surface of the substrate and are spaced apart from the first surface by different distances. The first and second magnetoresistors have respective main axes of magnetization transverse to one another, and respective secondary axes of magnetization transverse to one another. The method further includes forming a first magnetic-field generator configured to generate a first magnetic field having field lines along the main axis of magnetization of the first magnetoresistor, and forming a second magnetic-field generator configured to generate a second magnetic field having field lines along the main axis of magnetization of the second magnetoresistor.

    Abstract: An electronic device for detecting the presence of an occupant on board a vehicle includes an audio sensor to acquire sound-sensing signals on board the vehicle. A movement sensor acquires movement-sensing signals associated with movement of the vehicle and an environmental sensor acquires environmental-sensing signals on board the vehicle. A processing unit is coupled to the audio sensor, movement sensor, and environmental sensor processes the respective sound-sensing signals, movement-sensing signals, and environmental-sensing signals to monitor the presence on board the vehicle of the occupant and the absence of a responsible person to determine a situation of danger and to activate a corresponding alarm warning.
