Controlling Light Source Intensity Patents (Class 250/205)
  • Patent number: 11368054
    Abstract: A power beaming system delivers electric power in laser light from a first location to a remote second location. The laser light has a high energy intensity level defining a hazardous illumination area and a low energy intensity level defining a safe illumination area. The system includes guard circuitry emitter(s) and corresponding detector(s). The guard circuitry forms a detection area about the hazardous illumination area to detect objects in proximity to the hazardous illumination area. A controller directs the guard and power beam circuitry according to sequentially activated safety modes to operate at a low energy intensity level, to scan in a defined pattern, to adjust operation of the detector(s), and to set guard circuitry parameters based on a time value, an object detection value, or a change to the delivered electric power. An output coupled to the controller and power beam circuitry controllably permits or prevents operation at the high energy intensity level.

    Abstract: In one aspect, an object detection system is provided that adapts to the distance between the emitter and receiver. The system may utilize a range determining operation whereby the receiver will adjust an operation threshold, such as the detected signal strength required for the receiver to indicate that no object is present. The system may increase the threshold of the receiver as the strength of the received signal from the emitter increases, and upon certain conditions, decrease the threshold of the receiver as the strength of the received signal decreases. The system may utilize different receiver thresholds corresponding with different distance ranges between the emitter and receiver. By increasing the threshold of the receiver, the system may disregard low-level reflected light, thereby avoiding ignoring legitimate obstructions, while allowing the system to operate reliably over a wide physical range between the emitter and receiver.

  • Patent number: 11087155
    Abstract: An identification device includes: an operation generator that generates a first operation pattern to be executed by a first moving body among moving bodies, and transmits the first operation pattern to the first moving body; an operation detector that detects second operation patterns executed by the moving bodies, using at least one image obtained by at least one image obtaining device; and a target identifier that obtains, from the first moving body, a time at which the first moving body executed the first operation pattern, and compares the first operation pattern with a second operation pattern detected at the time from second operation patterns to determine whether these patterns match each other. When determining that they match each other, the target identifier identifies, as the first moving body, a moving body that is included in at least one image and executed the second operation pattern detected at the time.

  • Patent number: 11077690
    Abstract: A printing apparatus of this invention scans with a tester a testing chart printed by a printing controller to acquire testing image data. A total amount of displacement calculator calculates an amount of displacement of a recording position including a direction of misregister as a total amount of displacement, based on a large amount of displacement determined by a large amount of displacement determiner, a direction of displacement detected by a direction of displacement detector, a shift amount corresponding to an amount of displacement detecting chart determined by an amount of displacement detecting chart determiner, and a peak position of the amount of displacement detecting chart determined by the amount of displacement detecting chart determining unit. Thus, since a total amount of displacement of the misregister can be calculated only by printing the testing chart on web paper WP, an amount of displacement of the misregister in the transport direction can be obtained easily in a short time.

  • Patent number: 11044403
    Abstract: Power consumption needed to illuminate a subject is reduced and the subject is continuously monitored. Each of a plurality of light sources emits light to the subject. An imaging circuitry obtains a captured image by imaging the subject. A controller performs light emission control to change a light source that emits light from among the plurality of light sources and causes the imaging circuitry to image the subject. A determiner determines whether a detection target that is pre-determined exists in an image area that is a part of the captured image obtained by the imaging circuitry and corresponds to the light source that emits light during imaging for obtaining the captured image.
