Publication number: 20240104587Abstract: 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.Type: ApplicationFiled: November 27, 2023Publication date: March 28, 2024Applicant: NEC CorporationInventors: Azusa FURUKAWA, Kan ARAI, Kei SHIBUYA, Hiroshi HASHIMOTO, Ken HANAZAWA, Makiko AKIGUCHI

Patent number: 11844639Abstract: 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.Type: GrantFiled: October 29, 2021Date of Patent: December 19, 2023Assignee: GE Precision Healthcare LLCInventors: Jiahua Fan, Ming Yan, Jed Douglas Pack, Priti Madhav, Kentaro Ogata, Ken Arai
