  • Publication number: 20180080996
    Abstract: According to an embodiment of the present invention, deterioration of a non-aqueous electrolyte power storage element is detected based on a first increase rate and a second increase rate, the first increase rate being an increase rate of a direct current resistance value obtained by measuring the non-aqueous electrolyte power storage element over a first time period, the second increase rate being an increase rate of a direct current resistance value obtained by measuring the non-aqueous electrolyte power storage element over a second time period that is longer than the first time period.

  • Publication number: 20160191890
    Abstract: In an image processing apparatus, an image acquiring unit acquires a first image and a second image that form stereoscopic images. A first sub-image extracting unit extracts first sub-images from the first image. A second sub-image extracting unit extracts second sub-images from the second image. A matching unit matches each pair of the first and second sub-images to determine a degree of similarity therebetween. A similar sub-image setting unit sets the second sub-image having a highest degree of similarity to the first sub-image to be a similar sub-image to the first sub-image. A brightness comparing unit compares in brightness each pair of the first and second sub-images. The matching unit is configured to, if a result of comparison made by the brightness comparing unit between a pair of the first and second sub-images is out of a predetermined brightness range, exclude such a pair of the first and second sub-images.

  • Publication number: 20160093859
    Abstract: An energy storage device includes: an electrode having a composite layer formed by applying a composite directly or indirectly onto a substrate and a non-applied portion, onto which the composite is not applied; and a separator layered on the electrode to face the composite layer. Here, a drawn area is formed in at least. a part of the non-applied portion, and an intermediate layer is interposed at least between the drawn area and the composite layer.
