A service providing apparatus has a first communication unit, a connection information generator, an existence detector, an existence confirmation request receiver, a connection information transmitter, an authentication unit, and a service providing unit. The second communication unit performs wireless communication with the service receiver located in a second wireless area narrower than a first wireless area. The existence confirmation request receiver receives the existence confirmation request signal transmitted by the service receiver through the second communication unit when the service receiver detects to be within a prescribed distance. The service providing unit connects with the service receiver authenticated by the authentication unit, and provides services to the service receiver through the first communication unit.

Service providing apparatus, service providing program and service providing method

In a communication system having a first communication device and a second communication device for carrying out communications by setting up a communication link, the identification code generated at one of the first and second communication devices is presented to the other, and the authentication data are generated by using this identification code at the both of the communication devices, so that the illegal acquisition of the identification code can be prevented and the security performance can be improved.

Short range radio communication system with using improved authentication scheme

A gate entry system for regulating passages of passengers is formed by a wall unit for forming a passageway that is extended along a passing direction of the passengers, a gate unit provided at an exit side of the passageway, which is capable of being opened or closed to regulate the passages of the passengers, human sensors for sensing the passengers in the passageway, a radio communication unit for detecting a number of passengers entering into the passageway according to outputs of the human sensors, and carrying out transmission/reception of data with respect to at least one terminal device of one passenger, and a control unit for controlling opening or closing of the gate unit according to the data received by the radio communication unit.

Gate entry system using short range radio communications with user terminal devices

A data transmitting and receiving method applied to a portable communication terminal apparatus which communicates with at least one destination and a ticket gate, the method comprising receiving a ticket information item via a public network to obtain a plurality of received ticket information items, storing the received ticket information items in a memory device, designating one of the ticket information items in the memory device to obtain a designated ticket information item, displaying the designated ticket information item on a display, establishing a first radio channel for the portable communication terminal apparatus to perform communications with the ticket gate, in preference to other communications with the destination, releasing a second radio channel which is used for communicating with the destination, before establishing the first radio channel, communicating with the ticket gate via the first radio channel on the basis of the ticket information item displayed on the display.

Data transmitting and receiving method and portable communication terminal apparatus

An X-ray CT system includes a fixed frame portion and a rotating frame portion. Being provided with X-ray tubes, the rotating frame portion is arranged so as to rotate with respect to the fixed frame portion. Vane members for feeding air are secured on the rotating frame portion. In operation, with the rotation of the vane members together with the rotating frame portion, cool air is introduced into the rotating frame portion. Consequently, heated instruments, such as the X-ray tubes, in the rotating frame can be cooled down effectively.
