Abstract: There are an updating method of an electronic tag and an update system of the electronic tag performed by the electronic tag which displays sorting information, and a controller and an access point disposed inside a vehicle such as a truck. The controller requests an external server to transmit information on the electronic tag, and the sorting information corresponding to information on a parcel to which the electronic tag is fixed, and transmits the obtained sorting information to the access point. Further, the access point transmits the sorting information to the electronic tag, and the electronic tag updates the display of the sorting information. In this manner, the electronic tag can be updated by using an idle time during delivery.

Abstract: A system for detecting a person being interested in a target includes a camera configured to capture an image of a location in front of a target area, a memory configured to store instructions and position information with respect to the target area, and a processor that executes the instructions to perform operations including receiving the image from the camera, detecting a face of person within the image, detecting a face direction in accordance with the detected face, and determining whether the person looks at the target area in accordance with the detected face direction and the stored position information with respect to the target area.

Abstract: A method includes detecting status of stock displayed on stocking place like a shelf, and transmitting information based on the status of stock to deliverer having the stock a predefined receiver.

Abstract: A communication terminal capable of seamless reproduction of stream data even when structure of an ALM tree changes during the reproduction of stream data includes a control unit which causes a reproduction unit to start reproduction of a stream data packet at a time point which is later than a predetermined time point by a total of all delay times corresponding to a communication path from the communication terminal to a leaf terminal. The delay times are obtained by an obtainment unit.

Abstract: A communication terminal (100) is one of communication terminals each having one parent terminal and zero or more child terminals. The communication terminals form an Application Layer Multicast (ALM) tree to sequentially distribute retransmission data of stream data from the parent terminal to the child terminal. The communications terminal (100) includes: a reproduction delay time determining unit (1010) determining a reproduction delay time based on a longest round-trip delay time among round-trip delay times of sections between a root terminal and the communications terminal (100), each of the round-trip delay times being required for transmission and reception of data through one of the sections between two neighboring terminals of the communications terminals on the ALM tree; and a reproduction control unit (1020) reproducing the stream data received from the root terminal, with the stream data delayed by the reproduction delay time determined by the reproduction delay time determining unit (1010).
