Abstract: A reception sensitivity is measured at a high precision. An access terminal function portion includes the transmitter part and receiver part of a communication terminal in a radio communication system. A path switch part effects switching to connect the input ends of receivers to antennas or to terminate them. The path switch part switches the paths of a signal from a transmitter and signals toward the receivers. An access point controller adjusts a packet error rate into a predetermined range, and obtains the reception sensitivity based on the transmission power of the access terminal function portion after the adjustment.

Abstract: Provided are a stream distribution system and a failure detection method capable of easily identifying the cause of quality loss in stream distribution. This stream distribution system includes a first server for communicating with a client terminal via a router and sending stream data, and a second server configured as a redundant server of the first server and connected to the first server. The first server has a communication status notification unit for sending a connection management table concerning the communication with the client terminal to the second server. The second server has a packet recording unit for acquiring a mirror packet, which is a copy of a packet sent to the first server, from the router, and a network failure monitoring unit for detecting a failure in a network between the first server and the client terminal based on the connection management table and a packet buffer.

Abstract: In network setting, when setting inputted from a management terminal is inputted into management agent of a CPU blade, the management agent performs network setting to a device driver of the CPU blade, performs setting of NIC to the device driver of the CPU blade and creates network setting information required for a port of an Ethernet switch module unit connected to the NIC to notify the same to a management module unit. The management module unit recognizes a port of Ethernet switch module units which corresponds to the NIC and performs network setting to the port of the Ethernet switch module based on the acquired network configuration information. Accordingly, a technology capable of easily performing the setting of network in a composite computer apparatus in a short time is provided.

Abstract: There are provided a radiation detection module, a printed circuit board, and a radiological imaging apparatus which make it possible to enhance spatial resolution without increasing channel number, and thereby to perform high-accuracy diagnosis. The radiation detection module includes a plurality of radiation detectors, and a wiring board on which the plurality of radiation detectors are mounted in a manner of being arranged in at least a radiation traveling direction. Here, on the wiring board, a pair of the radiation detectors which are adjacent to each other in the radiation traveling direction are electrically connected to each other, thereby configuring one detector structure (i.e., detection channel). Moreover, the radiation detectors are mounted onto the wiring board such that respective connection parts of electrodes, which are to be electrically connected to each other, are in a mutually-facing state.
