  • Patent number: 7802237
    Abstract: A program generation program used in a personal computer processes information on relationship between an action and a pair of a state of a system and an event to create a program for incorporating a new state in a state transition table. The computer reads the state transition table in a storage medium and selects the state specified in the state transition table. The computer generates a program that determines whether the selected state is an exceptional state or a normal state on the basis of state information in the state transition table. Based on the result of the determination, the program performs an action including a state transition or a process allocated to the exceptional state specified in the state transition table when the state is the exceptional.

  • Publication number: 20100188614
    Abstract: A driving apparatus includes an inverter to supply an AC voltage to Cold Cathode Fluorescent Lamps (CCFLs) to be driven. A first detection signal generation unit generates a first detection signal occurring by driving a first CCFL with the AC voltage. A second detection signal generation unit generates a second detection signal occurring by driving a second CCFL with the AC voltage. An abnormality detection circuit generates an abnormality detection signal corresponding to a difference between amplitudes of the first detection signal and the second detection signal. The driving apparatus compares the abnormality detection signal with a predetermined threshold value to execute a circuit protecting operation in accordance with a comparison result.

  • Publication number: 20090287770
    Abstract: The present invention includes: a step of creating at least a play list including reproduction start times of the display terminal devices (1) and acquisition destination data indicating acquisition destinations of the creative data; and a step of transmitting the play list and the creative data to the display terminal devices (1) via the normal relay server devices (30) and the super relay server devices (20). The play list creating step creates the play list by determining the acquisition destination data in such a manner that the creative data is distributed preferentially to the super relay server devices (20) rather than to the normal relay server devices (30) and that the normal relay server devices (30) acquire the creative data from the super relay server devices (20). Because of this, the load on distribution devices for distributing creative data is reduced.
