Abstract: A speed limit display device for a vehicle, includes an indicator configured to display information related to a speed limit of a road; an image obtaining device configured to capture an image of a landscape and obtain image data of the landscape; and an electronic control unit configured to detect the speed limit indicated on a traffic sign in the captured landscape, and display the speed limit on the indicator. The electronic control unit is configured to i) determine whether a predetermined condition is satisfied when the traffic sign is detected, the predetermined condition including a condition that a distance between the vehicle and the traffic sign be less than a predetermined distance, ii) display the detected speed limit when the predetermined condition is satisfied, and iii) not display the detected speed limit when the predetermined condition is not satisfied.

Abstract: An electrical activity monitoring device based on an RFID sensor device attachable to a power cable of an electrical device for monitoring the electrical status of the electrical device. The device comprises an antenna element which performs the dual functions of magnetically coupling with an electrical pulse generated in the power cable in response to a change of electrical power state of the electrical device and to wirelessly transmit data to an RFID reader. An electrical activity monitoring apparatus is also provided for monitoring the electrical status of at least one electrical device connected to a power supply network by a respective power cable provided with an RFID sensor device. The electrical activity monitoring apparatus comprises an RFID reader for communicating with the RFID sensor device.

Abstract: A door-lock control method adopted by a door-lock device and a computer program is present. The method comprises: broadcasting a connecting message in a WPAN at the door-lock device; controlling a mobile device to establish a connection with the door-lock device via the WPAN when receiving the connecting message at the computer program; sending an unlocking command via the connection at the computer; and unlocking a door-lock thereon when receiving the unlocking command at the door-lock device. This application can omit the operations which the householder needs to do manually on the mobile device or the door-lock device, and effectively improves the convenience of use and reduces the waiting time of completing unlocking the door-lock.

Abstract: A vehicular assistance device, which is equipped to a vehicle and performs a wireless communication with a facility-side device to receive assistance information useful to a user from the facility-side device, includes a facility ID reception portion receiving a facility ID used for identifying a facility from the facility-side device, an area information acquisition portion acquiring area information related to a position of the facility, a position information acquisition portion acquiring position information of the vehicle, a determination portion determining whether the received facility ID is valid based on the position information of the vehicle and the area information related to the facility corresponding to the received facility ID, and a user ID transmission portion, when the facility ID is valid, transmitting, to the facility-side device, a user ID used for identifying the user as a request for transmitting the assistance information.

Abstract: A method of managing objects in a site includes producing a guided surface wave with a guided surface waveguide probe, the guided surface wave having sufficient energy density to power object identification tags in an entirety of a site; receiving reply signals from the object identification tags, each object identification tag associated with an object; and identifying geolocation of one or more the objects according to received reply signals from the object identification tags that are associated with the one or more of the objects.

Abstract: A vehicle includes a gateway controller configured to interface a diagnostic port to a vehicle communication network. In response to a perimeter alarm system being in an armed state, transfer of messages from the diagnostic port to the vehicle communication network is inhibited. A change session diagnostic request received from the diagnostic port is transferred to the vehicle communication network in response to vehicle speed being less than a threshold and an ignition switch begin in a run position. The transfer of the change session diagnostic request is otherwise inhibited unless intended for a module designated for reprogramming keys.
