摘要:
A mobile communication system comprises base stations, a mobile terminal and a control device. The mobile terminal comprises a report unit reports a reception power of a radio wave from a current station and a next station to the control device for each base station switch processing. The control device comprises a calculation unit calculates a first distance and a second distance. The first distance is the distance between the current station and the mobile terminal. The second distance is the distance between the next station and the mobile terminal. The control device comprises a database stores distance data between the base stations. The control device comprises an update unit updates the distance data by a minimum value of a sum of the first and the second distances.

According to one embodiment, a controller for a storage apparatus is disclosed having interfaces connectable to a host system, a first storage apparatus and a second storage apparatus. A data in the first storage apparatus and a data in the second storage apparatus are duplicates. A status table stores the operating state regarding the first storage apparatus and the second storage apparatus, wherein the operating state indicates among writing, reading, or standing by. A monitor monitors the interfaces and set up the operating state into the status table. A buffer memory buffers the data for writing in the first storage apparatus and the second storage apparatus. A command response unit receives the data for writing and write-in request from a host system, and directs the writing of the data to the first storage apparatus and the second storage apparatus while making the buffer memory buffer the received data.
摘要:
The base station includes a notification module configured to notify a control center of output power data, a measurement module configured to measure a reception quality of each time slot from received radio signals of control data transmitted from other base stations via a control channel, and a transmission module configured to transmit reception quality data indicating the reception quality to the control center, along with data indicating the time slot selected by the base station. The control center includes a reception module configured to receive the output power data, the reception quality data, and the data indicating the time slot, and a construction module configured to construct adjacent base station data indicating adjacency relationship between the base stations by comparing the reception quality and the output power of each of the base stations, the reception quality being obtained by converting the reception quality data based on the time slot.

A controller is connectable to a host system and a plurality of storage devices. A monitor unit monitors operating status of a plurality of storage devices and sets the operating status of the storage devices in a status table. Upon receiving a write command from the host system, a command responding unit receives write data sent from the host system within a certain period of time after the write command, holds the write data received in a buffer memory, instructs a timer to start counting, sets a write destination for data in the status table, outputs a control signal that gives an instruction to write data to the storage device of the write destination, and returns a write completion response corresponding to the write command to the host system when receiving the deadline notification from the timer.

A rear beam has a first beam with right and left ends welded to right and left rear supports and a second beam welded to a front surface of the first beam along the right and left direction. The second beam is welded to the first beam so that an upper end portion of the second beam is above an upper end portion of the first beam and a lower end portion of the second beam is above a lower end portion of the first beam.

A disease control device has light emitting diodes (D1 to Dn) emitting green light and a controller (2) controlling a drive circuit (1) for turning on the light emitting diodes (D1 to Dn). The drive circuit (1) is controlled by the controller (2) to cause the light emitting diodes (D1 to Dn) to emit green light to irradiate plants with the light. The irradiation with the green light enhances resistance of the plants against diseases.

A travel mode setting device for a hybrid car capable of ensuring the security against car theft and convenience when the car is lent to the third party. The hybrid car has travel drive sources and selectively uses one of them and can travel in one of travel modes. Authenticating means separately authenticate the car user and creates authentication results. Limiting means limits the travel modes to the usable travel modes according to the results of the authentication by the authenticating means.

摘要:
According to one embodiment, a mobile communication system includes base stations each forming a wireless zone for wirelessly accommodating mobile terminals, and a control device accommodating the base stations. The control device includes a construction module, a prediction module and an instruction module. The construction module constructs a database regarding a history of handovers by the mobile terminals. The prediction module predicts a base station of the next connection destination of a mobile terminal being in communication and timing of a handover to the base station of the next connection destination on the basis of the database. The instruction module instructs the handover to the predicted base station to the mobile terminal being in communication before the timing comes.
