Abstract: The use of a wireless interface is dynamically changeable according to connection states of stations belonging to access points. Therefore, limited wireless interfaces are efficiently utilized without requiring operation in which the user conducts a complex setting operation. First, connection states of stations belonging to access points are measured. Based on information of the connection states, the connection destination of a wireless connection unit of an access point under consideration is changed over between an access point and a station.

Abstract: A communication quality measuring device measures communication quality for recognizing a communication state for a predetermined period. Then, the communication quality measuring device calculates a correlation period during which cases of communication quality measuring unit at a measured particular time. Then, the communication quality measuring device determines a communication quality result at the particular time based on correlation communication quality that is measured during the correlation period.

Abstract: A wastewater treatment apparatus (10) that treats the wastewater containing persistent substances, according to the present invention, includes a wastewater treatment bath (12) for treating a wastewater (11), an oxidizing reagent adding unit (14) for adding an oxidizing reagent (13) in the wastewater treatment bath (12), and an alkaline reagent adding unit (16) for adding an alkaline reagent (15) in the wastewater treatment bath (12). By making the wastewater in the wastewater treatment bath (12) in the alkaline condition, it is possible to completely decompose the persistent substances in the wastewater by the oxidation treatment using an oxidizing reagent.

Abstract: A small power generating system includes a turbine driven by a fluid, a power generator including a permanent magnet rotor having a permanent magnet and rotated together with the turbine and a plurality of stator coils each of which is comprised of a coreless coil, the rotor being rotated such that voltage is induced on the stator coils, whereby power is generated by the power generator, and a back yoke disposed at one of two opposed sides of the stator coils which is opposed to the other side thereof further confronting the permanent magnet of the rotor, the back yoke being made of a magnetic material with a predetermined electrical resistance.

Abstract: A camera control system consists of a plurality of camera apparatus, camera control units coupled to the plural camera apparatus, respectively, a transmission path connected to the camera units and a base station connected to the transmission path. The base station has a database and the database is stored with setting values concerning at least photographing direction, image quality and voice quality of the plural camera apparatus and the plural camera control units in a plurality of table formats. An arbitrary camera control unit has a memory unit. A desired setting value of those stored in the database is down loaded to the memory unit on the basis of a command from the camera control unit and the setting values of the plural camera apparatus and camera control units are modified with the down loaded setting value.
