  • Publication number: 20210323264
    Abstract: Provided is a decorative molded article that uniformizes the brightness of an uneven surface and inhibits whitening. The decorative molded article is provided with a protective layer having an uneven surface on an adherend, and satisfying the following requirement 1-1: <Requirement 1-1> A black plate is stuck to the surface of the article on the adherend side thereof via a transparent pressure-sensitive adhesive layer to prepare a sample A. A visible light inclined by 10 degrees from the normal direction of the sample A is made to run into the uneven surface, and based on the specular direction of the incident light as a reference angle, a luminous reflectance is measured every 0.2 degrees within a range of the reference angleĀ±5.0 degrees. When the luminous reflectance at ?5.0 degrees relative to the reference angle is represented by Y?5.0 and the luminous reflectance at ?4.8 degrees is represented by Y?4.8, a value represented by an expression of [(Y?4.8?Y?5.0)/((Y?4.8+Y?5.

  • Publication number: 20210294311
    Abstract: A work support system is capable of avoiding situations where a worker performs erroneous work. The system includes an identification unit which identifies a target of an inquiry from a worker based on a video acquired by an imaging device, a selection unit which selects determination model information corresponding to each of one or more targets of inquiry identified by the identification unit from a storage unit storing determination model information to be used in a determination model. A determination unit determines whether each of the targets of inquiry is correct by using each of the determination models in which the determination model information, which was selected by the selection unit, corresponding to each of the one or more targets of inquiry identified by the identification unit, has been set in the determination model. An output unit outputs a determination result of the determination unit.

  • Patent number: 9255943
    Abstract: A process of the invention analyzes a moving speed using acceleration data by an acceleration sensor and calculates a moving distance of the object. The process removes each of given candidate values of drift components from angular velocity data by a gyro sensor and generates relative azimuths data pieces. Based on the respective relative azimuths data pieces, the process calculates moving directions of the object. Using the moving distance and moving directions calculated, the process creates plural moving loci corresponding to the candidate values of drift components. By comparing the positions of actual starting and end points of moving in a building with the positions of starting and end points of each moving locus, the process evaluates the moving loci and determines an optimal moving locus out of the moving loci, based on the evaluation result.

  • Publication number: 20160005058
    Abstract: Since questionnaires are used according to the sensitivity marketing method in the related art, it is not possible to obtain answers from many people at the same time, and also, analysis of the answers requires a long time, which does not match life cycles of product development. Furthermore, there is a problem that credibility of the aggregate result is low without the use of biomarkers. A sensitivity evaluation system for evaluating distributed video information has a client system that transmits an evaluation request related to the video information to an information analysis system and transmits the video information, which is to be viewed by an examinee at a terminal. The terminal transmits a biosignal, which is measured by an apparatus that the examinee wears to the information analysis system which analyzes the biosignal, creates a report related to the video information, and transmits the created report to the client system.
