  • Patent number: 10436942
    Abstract: Statistically representing point-to-point photovoltaic power estimation and area-to-point conversion of satellite pixel irradiance data are described. Accuracy on correlated overhead sky clearness is bounded by evaluating a mean and standard deviation between recorded irradiance measures and the forecast irradiance measures. Sky clearness over the two locations is related with a correlation coefficient by solving an empirically-derived exponential function of the temporal distance. Each forecast clearness index is weighted by the correlation coefficient to form an output set of forecast clearness indexes and the mean and standard deviation are proportioned. Additionally, accuracy on correlated satellite imagery is bounded by converting collective irradiance into point clearness indexes. A mean and standard deviation for the point clearness indexes is evaluated. The mean is set as an area clearness index for the bounded area.

  • Patent number: 10380864
    Abstract: This watching system is provided with: a watching detection device that is provided with a cartilage conduction vibration source, a mastication sensor, and a bone conduction microphone and that is configured to be mounted on an ear such that the entry of the ear canal is opened; and a mobile phone or an in-home monitoring unit that receives watching detection signals from the mastication sensor and the bone conduction microphone by means of short-range communication and issues a notification to the outside. The watching detection device has an air conduction microphone and also functions as a hearing aid. When detection signals cannot be received from the mastication sensor or the bone conduction microphone for a predetermined time period, a notification is issued. The mobile phone and the in-home monitoring unit crosscheck watching detection information. The mobile phone also issues a notification of information indicating that there is no abnormality.

  • Patent number: 10366496
    Abstract: The invention relates generally to edge detection and presentation in thermal images. Infrared and visible light images comprising at least partially overlapping target scenes are analyzed. An edge detection process is performed on the visible light image to determine which pixels represent edges in the target scene. A display image is generated in which some pixels include infrared image data and in which pixels corresponding to edges in the visible light image include a predetermined color and do not include corresponding infrared image data to emphasize edges. Edge pixels in the display image can include exclusively the predetermined color, or in some examples, a blend of a predetermined color and visible light image data. Methods can include replacing one or the other of visible light edge pixels or corresponding infrared pixels with the predetermined color before combining the visible light and infrared image data to create a display image.

  • Patent number: 10339638
    Abstract: An image processing device and an image processing method capable of satisfactorily performing a point image restoration process of a visible light image and a point image restoration process of a near-infrared light image are provided. A point image restoration process is performed on luminance data Y indicating a visible light image and IR data indicating a near-infrared light image using a first point image restoration filter based on a first point spread function with respect to visible light of an optical system and a second point image restoration filter based on a second point spread function with respect to near-infrared light of the optical system. An appropriate point image restoration process is performed on the IR data so that restoration strength (second gain ?) in the point image restoration process for the IR data captured with radiation of near-infrared light is higher than restoration strength (first gain ?) in the point image restoration process for the luminance data Y.

  • Patent number: 10341586
    Abstract: The invention relates to a visible light image and infrared image fusion processing system and a fusion method. The fusion processing system comprises an image acquisition module, an image fusion module and an image display module, wherein the image fusion module is connected with the image acquisition module and the image display module. By adoption of the fusion method, the fusion ratio of a visible light image to an infrared image can be adjusted according to requirements, and detailed images are filtered and compared and then enhanced, so that detail information of a fused image is improved, and noise interference is avoided. Furthermore, fusion weights of the visible light image and the infrared image and the detail enhancement degree can be flexibly controlled through external parameter adjustment, and thus various display requirements are met.
