  • Publication number: 20200141544
    Abstract: Provided is a light-emitting diode-type illumination device which controls, at a high illuminance, the illuminance of directed light emitted by an LED element as a light source. This light-emitting diode-type illumination device 1 comprises a directed illuminance control means which directs the light emitted from a LED element 13 and controls the directed illuminance of the irradiated light, and a light-reflecting member 19 equipped with a convergent reflecting surface 19a positioned on the light-emitting side of the LED element 13. The light-reflecting member 19 is positioned so as to extend in the direction in which light is irradiated, symmetrically or asymmetrically with respect to the centerline of the LED element 13. The directed illuminance control means controls the directed illuminance of light obtained by directing and irradiating light emitted from the LED element 13.

    Abstract: When the measurement values measured by a first sensor among a plurality of sensors installed in a dispersed manner at a specific location, in first cycles are determined to be abnormal values, a control device activates the first sensor in second cycles that are shorter than the first cycles. Moreover, when the abnormal values are included in the trend of temporal variation, the control device activates a plurality of second sensors, which is installed around the first sensor, in the second cycles. Moreover, when the measurement values measured by the first sensor and the plurality of second sensors in the second cycles are included in the trend of surface-direction distribution, the control device outputs the measurement values measured by the first sensor and the plurality of second sensors.

  • Patent number: 10098071
    Abstract: An observation system includes a plurality of nodes and an observation apparatus that collects information from the nodes using multi-hop communication for communicating with the nodes. The observation apparatus includes a link quality indicator (LQI) determination section and an output control section. The LQI determination section determines whether an LQI received from a node using the multi-hop communication is larger than a first threshold. When the LQI is larger than the first threshold, the output control section outputs a reduction command to the node associated with the LQI, the reduction command being a command to change the amount of transmission power in the multi-hop communication.
