  • Patent number: 12149072
    Abstract: A rapid shutdown device (RSD) includes: a logic-and-analog circuit; an RSD ID storage for storing an unique RSD ID; a control command receiving circuit for receiving and decode a control command including a combination of an all-RSD turn-on command, a single-RSD turn-on command and a to-be-tested RSD ID; a switch circuit connected to the logic-and-analog circuit; and a bypass circuit connected between two output terminals of the RSD. When the switch circuit is turned off, the bypass circuit is turned on. The logic-and-analog circuit controls the on/off state of the switch circuit according to a decoding result of the control command receiving circuit and the unique RSD ID stored in the RSD ID storage. When the switch circuit is turned on, an output voltage received from a photovoltaic module coupled to the RSD is outputted via the RSD.

  • Patent number: 12140957
    Abstract: The present application is to provide a system for sensing and responding to a lateral blind spot of a mobile carrier and method thereof, which is applied for a mobile carrier during moving to a parking place. Firstly, a light scan unit and a depth image capture unit are used to scan a plurality of surrounding objects and capture a plurality of object depth images of the surrounding objects, and then a plurality of screened images are obtained according to a moving route of the mobile carrier for further obtaining correspondingly a plurality of forecasted lines to generate corresponded notice message for noting driver or ADAS. Due to the objects corresponding to the screened images and located on a blind position which is at one side of the mobile carrier, the notice message provides the driver preventing from the ignored danger by ignoring the blind position.
