Abstract: 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.

Abstract: A UPS monitoring part monitors a state of a UPS, on the basis of an information which was transmitted from the UPS which was connected to an information processing apparatus, and received by a UPS communication part. A UPS control part, on the basis of a result of that monitoring, generates a control information for individually controlling respective states of a plurality of electric power output parts of the UPS, in accordance with a condition of power-off of each load which was connected to the corresponding electric power output part, and carries out a control for transmitting it from the UPS communication part to the UPS.

Abstract: An apparatus for determining life of a battery which supplies charged electricity to an electrical appliance is equipped with a storage part for storing relationship between standard total values of discharge voltage drop amounts since a start of discharge of the battery and standard life values, a discharge voltage drop amount totalizer part for totalizing the discharge voltage drop amounts since the start of discharge with the battery being discharged, and a life determination part for determining the life of the battery from a measured total value of totalized discharge voltage drop amounts and the standard total values of the storage means.

Abstract: An interconnectable power supply module includes a battery; a battery charger for charging the battery; a power generator capable of converting an electrical charge stored in the battery to generate output power for an external load; a control unit for controlling operation of the power supply module; a power supply plug for receiving external power from an external power source; a power supply socket capable of coupling the external power received from the external power source to an adjacent power supply module; an external load output socket, selectively coupled to one of the external power source and the power generator, for providing output power to the external load; and a connecting terminal capable of coupling the external load output power to the adjacent power supply module.

Abstract: A liquid crystal display assembly including a plurality of individual liquid crystal displays formed on a pair of cooperating substrates with the displays isolated from one another by a sealing pattern served to define individual displays. One method of forming a plurality of liquid crystal displays includes the steps of applying a conductive pattern to one surface each of a pair of substrates, the pattern cooperating when the substrates are face to face to form the plurality of displays, providing sealing means on at least one of the surfaces prior to bringing said surfaces together and in a pattern isolating each of the plurality of displays to form a plurality of displays cells, filling the cells with liquid crystal material, sealing the cells by bringing the substrates together and cutting substrates to form the displays.
