摘要： A protocol delay measuring device (100) for preventing an increase of the processing overhead of a communication terminal attributed to a protocol delay measurement. The protocol delay measuring device (100) determines the protocol delay by using first and second timestamps created respectively before and after a processed packet is obtained from an unprocessed packet by IPsec processing by the communication terminal. An acknowledging section (104) creates an identifier of the unprocessed packet. A timestamp database (106) stores the created identifier along with the first timestamp and writes the identifier in a storage area where the identifier is kept the same before and after the IPsec processing by the communication terminal. A correlating section (108) reads the identifier from the storage area and extracts the first timestamp stored along with the same identifier as the read identifier in the timestamp database (106). A calculating section (110) calculates the difference between the extracted first timestamp and the second timestamp as the protocol delay.

摘要： A wireless communication device is quickly connectable to an access point of a destination service area without wasting power when the wireless communication device moves from a service area to a different one. When a state change detector of the wireless communication device detects that the received radio field intensity of the radio wave from the connected access point lowers to a threshold or less, a service area information acquirer acquires information on the service area where the wireless communication device is present and information on a neighboring service area. A profile information acquirer acquires profile information corresponding to the service area information. A priority order setter sets the order of priority to the acquired profile information in such a way that the access point of a neighboring service area neighboring to the service area formed by the connected access point is precedingly connected. According to the profile information to which orders of priority are set, a request for connection to the access point is made.

摘要： This electrical power-receiving apparatus makes it possible to suppress a decline in power supply efficiency in a variety of different circumstances while avoiding an increase in circuit scale. This apparatus comprises an impedance control unit (307) for sequentially switching through any one of a plurality of charging devices in a charging device group (310), as candidate charging devices for a supply destination to which electrical power is to be supplied. The impedance control unit (307) also selects from the candidates a charging device to which electrical power is actually supplied, on the basis of the difference between the impedance of the charging device group (310) for each candidate and the impedance of an electrical power receiving antenna unit (301), and causes electrical power to be supplied to the selected charging device.
