  • Publication number: 20240104587
    Abstract: In a familiarity degree estimation apparatus, a first video process unit calculates a time while a hand being viewed, which is a time when a customer is viewing the hand. A second video process unit calculates a time while an item being held, which is a time when the customer is holding an item. A familiarity degree estimation unit calculates a time while the item being viewed based on the time while a hand being viewed and the time while the item being held, and estimates that the longer the time while the item being viewed, the lower the degree of familiarity of the customer with respect to the item.

  • Publication number: 20240095671
    Abstract: An item management apparatus manages the number of items displayed on an item shelf. An acquisition unit acquires an ideal quantity indicating an ideal number of items to be displayed, and a current quantity indicating the number of items being actually displayed on the item shelf. A detection unit detects the number of times of taking out and placing back an item with respect to the item shelf. An ideal quantity correction unit corrects the ideal quantity based on the current quantity and the number of times of taking out and placing back the item.

  • Publication number: 20240087359
    Abstract: A customer analysis apparatus (10) includes an image acquisition unit (110) and an image processing unit (120). The image acquisition unit (110) acquires a first image generated by a first image capture unit (22) and a second image generated by a second image capture unit (24). The image processing unit (120) processes the first image and the second image. More specifically, the image processing unit (120) generates product information indicating a product (50) taken out from a product shelf (40), by processing the first image and the second image. Further, the image processing unit (120) generates customer attribute information of a customer taking out the product (50), by processing the first image. Then, the image processing unit (120) causes a result storage unit (130) to store the product information and the customer attribute information in association with each other.

  • Patent number: 11844639
    Abstract: A method includes acquiring a first dataset of projection measurements at a first energy spectrum and a second dataset of projection measurements at a second energy spectrum different from the first energy spectrum by switching between acquiring the first dataset for a set number of consecutive views at different projection angles at the first energy spectrum and acquiring the second dataset for the set number of consecutive views at different projection angles at the second energy spectrum. The set number of consecutive views is greater than one. The method includes supplementing both the first dataset with estimated projection measurements at the first energy spectrum and the second dataset with estimated projection measurements at the second energy spectrum to provide missing projection measurements at different projection angles not acquired during the imaging scan for the first dataset and the second dataset.

  • Patent number: 8727651
    Abstract: An elevating container includes an elliptically shaped main tube, a non-circularly shaped moveable support unit which moves upwardly or downwardly along an inner surface of a storage tube of the main tube without rotating, and a driving unit fitted to the main tube to rotate in threaded engagement to the support unit without moving upwardly or downwardly. A seal section at the lower end of the inner peripheral surface of the storage tube and a sealing cylinder at the lower end of the support unit are air-tightly fitted to each other. In addition, positioning ribs are provided at the lower end of the storage tube, and positioning notches are provided at the lower end of the moveable support unit. When the positioning ribs and the positioning notches are engaged with each other, a circumferential misalignment between the main tube and the support unit is corrected.

  • Patent number: 7540404
    Abstract: A packaging box (10) includes a pair of lids (2, 3), and the pair of lids (2, 3) have tongues (2b, 3b) extending from their heads and lid gluing portions (2c, 3c) arranged in specific areas on the outer surfaces of these tongues (2b, 3b). A body (1) of the packaging box (10) has a pair of body gluing portions (1f, 1g) individually glued to the lid gluing portions (2c, 3c) and at least one transverse split-open portion (5) for guiding a fracture in a side face of the packaging box (10). Both open-side ends (1e) have side-end split-open portions (6, 7) arranged so as to surround the body gluing portions (1f, 1g). Thus, even if the tongues provided at the heads of the lids are glued to side plates, the packaging box can be easily and accurately split and spread.
