  • Publication number: 20230095425
    Abstract: A quantum cascade laser device includes a QCL element; a lens; and a lens holder having a small-diameter hole, a large-diameter hole, and a counterbore surface. At least a part of a side surface of the lens is fixed to an inner surface of the large-diameter hole in a state where an edge portion of an incident surface of the lens is in contact with the counterbore surface. A central axis of the small-diameter hole is eccentric from that of the large-diameter hole. The side surface of the lens is positioned with respect to the inner surface of the large-diameter hole along a direction from the central axis of the large-diameter hole toward the central axis of the small-diameter hole. A central axis of the lens is disposed at a position closer to the central axis of the small-diameter hole than to the central axis of the large-diameter hole.

  • Publication number: 20220021954
    Abstract: Proposed is an information collection system and method capable of reliably collecting information even from sensors installed at locations where a vehicle cannot pass through, and also promptly collecting information of urgent nature. Each sensor not positioned on a route travelled by a travel vehicle transmits, to sensors of a subsequent stage in multihop wireless communication preset so that information is aggregated in a predetermined sensor positioned on the route travelled by the travel vehicle, information transmitted from sensors of a preceding stage in the multihop wireless communication, as well as its own information, and the sensor positioned on the route travelled by the travel vehicle transmits the aggregated information to a receiver.

  • Publication number: 20210351570
    Abstract: A quantum cascade laser device includes a semiconductor substrate, an active layer provided on the semiconductor substrate, and an upper clad layer provided on a side of the active layer opposite to the semiconductor substrate side and having a doping concentration of impurities of less than 1×1017 cm?3. Unit laminates included in the active layer each include a first emission upper level, a second emission upper level, and at least one emission lower level in their subband level structure. The active layer is configured to generate light having a center wavelength of 10 ?m or more due to electron transition between at least two levels of the first emission upper level, the second emission upper level, and the at least one emission lower level in the light emission layer in each of the unit laminates.

  • Patent number: 10769767
    Abstract: A monitoring system monitors a monitoring object apparatus sufficiently for practical use while suppressing battery power consumption. The monitoring system is provided a sensor terminal that is driven by a battery and acquires a measured value(s) of a measuring apparatus mounted in the monitoring object apparatus by executing image analysis processing on a captured image(s) obtained by photographing the measuring apparatus. A manager terminal monitors the measured value(s) of the measuring apparatus which is reported from the sensor terminal. When the measured value is out of a normal range, the manager terminal requests transmission of image data of an image area, which is necessary to check whether the measured value of the measuring apparatus is actually out of the normal range or not. The sensor terminal transmits the requested image data with the requested resolution to the manger terminal in response to the request from the manager terminal.

  • Patent number: 10521261
    Abstract: A management system retains a plurality of configuration information entries and a plurality of change information entries. Each of the plurality of configuration information entries is information which represents a change of a configuration of a computer system and includes at least a portion of: information which is included in information which is periodically collected from the computer system; and information which is identified on the basis of first and second information which is respectively polled from the computer system in first and second collection. Each of the plurality of change information entries is information which represents a change of a configuration of the computer system and includes manually inputted information relating to the change of configuration of the computer system. The management system associates at least one of the plurality of change information entries with at least one of the plurality of configuration information entries and manages same.
