An autonomous driving vehicle includes a user detection monitoring device and a start control device. The user detection monitoring device detects a user who got out of the autonomous driving vehicle after the autonomous driving vehicle stopped at a destination as an alighted user and monitors the alighted user. The start control device maintains a stopped state of the autonomous driving vehicle after the alighted user was detected until a start condition is satisfied and, if the start condition is satisfied, permits a start of the autonomous driving vehicle. The start condition is one of a condition indicating that the alighted user at least moves out of a movement determination area around the autonomous driving vehicle and a condition indicating that the alighted user is present in the movement determination area but remains at the same position for a certain period of time or longer.

A method and system for capturing and annotating measurement data includes communicatively connecting a mobile computing device to one or more measurement devices, and receiving measurement data from the one or more measurement devices. The mobile computing device stores the received measurement data and annotates the stored measurement data with metadata. The metadata includes group identifying information that associates the stored measurement data with other data having similar group identifying information. In at least one embodiment, measurement data is automatically associated with the group identifying information based on the measurement data being captured within a predetermined amount of time of each other or within a predetermined distance of each other as determined by a positioning system. The metadata may include, for example, one or more of a time, a location, a test point, a work order, a task list, a job instruction, a technician identifier, a text note, a voice note, an image, a video, and an image annotation.

The invention detects foreign objects FO near a primary coil 100 of an induction charger. A sensors 111 of a sensor array 110 output sensing signals in response to magnetically coupling the alternating magnetic field 103 produced by the primary coil. A controller 165 connected to each sensor 111 scans the sensing signals and determines whether there is a foreign object perturbing the magnetic field 103 near a sensor. The magnetic field has a spatial distribution that varies by location across the primary coil area. Each sensor has a magnetic field sensing sensitivity that is inversely proportional to the magnetic intensity of the magnetic field produced by the primary coil at a location of the sensor, to reduce the collective dynamic range of the signals, thereby contributing to maintaining a high accuracy in signal sampling. A reference sensor coil 155 compensates for magnetic field drift of the primary coil.
