Method for authorization of service requests to service hosts within a network

A method for authorization of service requests to service hosts within a network, wherein the communication within the network is based on a routing mechanism, according to which user terminals within the network are associated with routable network addresses, is characterized in that the service host sends a nonce included in a request message to the network address of a requesting user terminal, and that the user terminal resends the nonce or a value inferable from the nonce by the service host as well as by the user terminal included in a response message to the network address of the service host.

Multiple access apparatus and method using power line

Provided is a telecommunication apparatus and a telecommunication method accomplishing a one-to-many, many-to-one, and many-to-many simultaneous accesses in a power line telecommunication of a code division multiple access (CDMA) by using an AC power line (including the ground).A comprisal includes an external power line model 1, a power distribution board 2 and an indoor power line model 3 which is connected to a power line by way of a capacitor for shutting off a sine wave of a power signal of a low frequency; a terminal station 5 and a base station 4 perform a power line telecommunication by way of a plug outlet; and the terminal station 5 controls and manages electric appliances installed in the indoor power line model 3. The terminal station 5 and base station 4 which are connected to the power line are connected to the Internet by way of a line; the base station 4 comprises a media converter 7 and a data link controller 8 which are connected to an external data bus, and also a power line telecommunication controller 9 for controlling a transmission and reception of an information signal and a synchronous signal; the terminal station 5 comprises a power line telecommunication controller 9 for controlling a transmission and reception of an information signal and a synchronous signal, thereby accomplishing an apparatus and method for carrying out a power line telecommunication.

Battery management system and battery management method

The time and effort of the user when exchanging batteries can be minimized, and security can be sufficiently ensured in user authentication. A battery exchanger (3) is provided with a camera (11) for capturing an image of a visitor, and a management server (4) performs face verification to determine if the visitor is an authentic user according to face image information of the visitor acquired from the image captured by the camera. Based on the face verification result, the management server determines if battery exchange is permitted, and notifies the determination result to the battery exchanger. Further, based on identification information of the battery pack brought in by the visitor, the management server performs battery verification to determine if the battery pack brought in by the visitor is permitted to be exchanged, and based on the result of the battery verification, determines if the battery exchange should be permitted.

Protection circuit for robot control device

A first current cut-off unit that cuts off a current input from a power-supply-voltage input terminal connected to an AC power source when a current value of the current exceeds a preset threshold, and a second current cut-off unit that cuts off a current output from the first current cut-off unit when a voltage value of a voltage applied from the power-supply-voltage input terminal exceeds a preset threshold are configured. A current cut-off element provided on a current path from the power-supply-voltage input terminal toward a DC output terminal, and a resistor that draws a current having passed through the current cut-off element toward a ground are provided as the first current cut-off unit.
