Based on information that is transmitted to a UPS communication part by UPSs connected to an information processing apparatus, a UPS monitoring part monitors the states of the UPSs. A UPS control part employs the monitoring results to generate control information for controlling the state of at least one of the UPSs, and permits the UPS communication part to transmit the control information to the UPS that is to be controlled. The present invention can be applied for a computer having a redundant power supply function.

Materials transparent to terahertz waves are very limited, and it is difficult to obtain the required performance by selecting the material. Further, it is also difficult to search for a novel material. Therefore, by letting a known material transparent to terahertz waves have a photonic crystal structure and controlling the structure, an optical waveguide having the required properties is provided. An optical waveguide for propagation of far-infrared radiation in the terahertz region, which optical waveguide is made of a fluorinated amorphous polymer. Particularly preferred is a polymer having a fluorinated aliphatic ring structure in its main chain, obtained by cyclopolymerization of a fluorinated monomer having at least two polymerizable double bonds.

Data are input from a geomagnetic sensor that detects magnetic fields in three axial directions, and magnetic field data are measured on the basis of the input data. The measured magnetic field data are sequentially stored, and a determination is made as to whether a plurality of the magnetic field data thus stored lie within a same plane in a three-dimensional orientation space. When it has been determined that the plurality of the magnetic field data lie within the same plane in the three-dimensional orientation space, center coordinates of a circular arc where the stored magnetic field data lie are calculated, as provisional offset values, on the basis of the magnetic field data and in accordance with a predetermined algorithm. Magnetic field data measured after the calculation of the provisional offset values is corrected with the provisional offset values, and an arithmetic operation is performed for determining orientation data on the basis of the corrected magnetic field data.

A magnetic sensor 10 includes GMR elements 11-18, and heating coils 21-24 serving as heat generating elements. The elements 11-14 and 15-18 are bridge-interconnected to constitute X-axis and Y-axis sensors, respectively. The heating coils 21, 22, 23, and 24 are disposed adjacent to the elements 11 and 12, the elements 13 and 14, the elements 15 and 16, and the elements 17 and 18, respectively. The heating coils 21-24, when electrically energized, heat mainly the adjacent elements. Therefore, the elements can be heated and cooled in a short period of time in which constant geomagnetism can be ensured. Data for compensation of temperature-dependent characteristic (ratio of change in sensor output value to variation in element temperature) is obtained on the basis of the temperatures of the elements before and after the heating, and the magnetic sensor outputs before and after the heating. Subsequently, the temperature characteristics of the elements are compensated on the basis of the data.

A magnetic-sensor controller includes an input section, a perpendicular-bisector calculation section, a storage section, and a setting section. The input section successively inputs a plurality of magnetic data sets successively output from a three-dimensional magnetic sensor. Each magnetic data includes three components. The perpendicular-bisector calculation section calculates, for each pair of two of the magnetic data sets, a perpendicular bisector of two points corresponding to the two magnetic data sets. The storage section stores a plurality of perpendicular bisectors. The setting section statistically approximates, by a single point, a region where the plurality of perpendicular bisectors stored in the storage section meet, and sets an offset of the magnetic data set on the basis of the single point. The magnetic-sensor controller enables accurate setting of an offset even when the magnetic field strength changes.
