Patent number: 9946357Abstract: A movement of an object is recognized as a predetermined movement, by transmitting signals between transmitter-receiver pairs, which are reflected from the object. A first event is recorded for one of the transmitter-receiver pairs if a reflected signal meets a predetermined proximity criterion, and a second event is recorded for a second transmitter-receiver pair if, after the first event, a subsequent reflected signal meets a predetermined proximity criterion. The first and second events are used to identify the movement.Type: GrantFiled: May 11, 2016Date of Patent: April 17, 2018Assignee: Elliptic Laboratories ASInventor: Tobias Dahl
