Patent number: 10013119Abstract: The shape or position of an object is estimated using a device comprising one or more transmitters and one or more receivers, forming a set of at least two transmitter-receiver combinations. Signals are transmitted from the transmitters, through air, to the object. They are reflected by the object and received by the receivers. A subset of the transmitter-receiver combinations which give rise to a received signal meeting a predetermined clarity criterion is determined. The positions of points on the object are estimated using substantially only signals from the subset of combinations.Type: GrantFiled: May 13, 2016Date of Patent: July 3, 2018Assignee: ELLIPTIC LABORATORIES ASInventor: Tobias Dahl

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

Patent number: 9329728Abstract: A first electronic device is operated in the presence of a second electronic device. Both are configured to transmit acoustic signals, the first being configured to transmit signals with a first characteristic. The first device determines the presence of the second device and thereafter transmits acoustic signals having a second, signal characteristic, different from the first characteristic, and giving a reduced interference between signals transmitted from the first and second devices respectively than the first signal characteristic. Acoustic signals comprising reflections of the transmitted signals from an object are received at the first device, and are used to characterise the motion of the object and thereby control a function of the first device.Type: GrantFiled: October 7, 2010Date of Patent: May 3, 2016Assignee: Elliptic Laboratories ASInventor: Tobias Dahl

Patent number: 9152276Abstract: The motion of an object is characterized by transmitting acoustic signals over first and second transmitter-receiver channels. Information relating to signals received over the first channel is compared with information relating to signals received over the second channel, to identify a similar pattern in both channels arising from reflections from the object. A relative timing difference between the channels, associated with the similar pattern, is used to characterize the motion of the object.Type: GrantFiled: September 22, 2010Date of Patent: October 6, 2015Assignee: Elliptic Laboratories ASInventors: Tobias Dahl, Tom Øystein Kavli, Trine Kirkhus
