  • Publication number: 20210150004
    Abstract: A control device includes a storage unit that stores an authentication ledger, an authorization ledger, operation information, and operation recording target information. An authentication management unit, in a case of receiving authentication information from one information processing device, performs an authentication determination. An authorization unit determines whether to authorize the processing request of the one information processing device with the authorization ledger. An execution authorization unit, in a case in which the processing request authorized is a request for changing an operation state of the device, determines whether to authorize an execution of the processing request from the operation information, and, in a case of authorizing, causes the control execution unit to execute the processing request, and, in a case of not authorizing, transmits an error response to the one information processing device.

  • Patent number: 8508492
    Abstract: In a touch panel, one of conductive layers on a bottom of an upper substrate and on a top of a lower substrate is formed of belt-shaped conductive layers. The other is a single conductive layer facing the belt-shaped conductive layers. The single conductive layer is provided with a pair of electrodes in positions corresponding to both ends in a direction where the belt-shaped conductive layers extend. When the upper substrate is pressed while a voltage is applied between the pair of electrodes, the top and lower conductive layers contact with each other. Then, a voltage value corresponding to the pressed position in the direction where the belt-shaped conductive layers extend is generated from any of the belt-shaped conductive layers. From the voltage value and the position of the belt-shaped conductive layer from which the voltage value is generated, a pressed position on the upper substrate can be detected.

  • Patent number: 8363364
    Abstract: A branch wire L5 from the voltage detection circuit 14 is inserted in the zero-phase-sequence current transformer ZCT in the direction from the load side to the external power supply side. For this configuration, the zero-phase-sequence current transformer ZCT is to detect unbalance of the sum of current flowing in the first and second conductive wires L1, L2 and the current flowing in the branch wire L5. Therefore, the present invention can accurately detect occurrence of electrical leakage.

  • Publication number: 20110315534
    Abstract: A light guide sheet guides light emitted from a light introducer. The light guide sheet includes a film-shaped substrate, a light emitting section formed on the substrate, and a belt-shaped light-blocking section. The light emitting section reflects or scatters light transmitting in the substrate to the outside. The light-blocking section is formed in the substrate by coloring a position of the substrate to a color. In the position, the light emitting section is not formed. The color absorbs the light which is emitted from the light introducer. The light emitting section can alternatively be composed of a plurality of projections and/or a plurality of recesses. Such a light-blocking section is formed in a position of the substrate where the projections and/or the recesses are not formed.

  • Publication number: 20110280024
    Abstract: The light guide sheet has a base of a light transmissive film, a first light-extracting section, and a second light-extracting section. The light-extracting sections having pits and projections are formed on a surface of the base. The base has a first color converter at least at a part corresponding to the position having the first light-extracting section in a thickness direction of the base. The first color converter converts light from a light source into a first color. Forming a color converter for predetermined color at each part corresponding to a plurality of the light-extracting sections allows the one color emitted from a light-emitting element to be converted into differently colored light beams at the light-extracting sections. The structure offers various patterns of illumination without increase in number of the light-emitting element.
