Patent number: 11144153Abstract: A system for detecting a user input to a device comprises a display arrangement (4) arranged to provide a display (20) on a surface. An optical proximity sensing arrangement (6, 8) is configured to produce touch information relating to whether an input object is within a threshold distance of the surface. An acoustic position sensing arrangement (10, 12, 14, and 16) configured to produce position information relating to a position of the input object on the surface. A processing arrangement configured to determine an input to the device from the position information only when it determines from the touch information that the input object is within the threshold distance of the surface.Type: GrantFiled: December 6, 2018Date of Patent: October 12, 2021Assignee: Elliptic Laboratories ASInventors: Guenael Thomas Strutt, Tom Kavli, Steven Lewis

Patent number: 10642370Abstract: An electronic device (1) such as a cell phone, or a proximity detector for an electronic device (1), has an ultrasound transmitter (5), an ultrasound receiver (6), and a processing system. It transmits an ultrasonic sine-wave signal from the transmitter (5), and receives the ultrasonic sine-wave signal, through air, at the receiver (6). It detects when the frequency of the transmitted signal and a frequency of the received signal satisfy a predetermined difference criterion, and uses this to determine whether to disable or enable a touch or touchless input (2) on the device (1).Type: GrantFiled: February 9, 2017Date of Patent: May 5, 2020Assignee: ELLIPTIC LABORATORIES ASInventors: Thomas Børstad, Tom Kavli

Patent number: 10432778Abstract: A portable communications device comprises an interactive touchscreen display (20) having a transparent outer surface member occupying substantially all of a front surface of the communications device. A casing provides a rear surface of the communications device. The device further comprises an audible sound transmitter and an audible sound receiver arranged so as to receive vocal sounds produced by a user when the device is placed against the user's head. An ultrasonic transmitter (24) is separate from the audible sound transmitter. An elongate aperture (28) has a minimum dimension less than 100 ?m located between the transparent outer surface member and the casing. A channel connects the elongate aperture and the ultrasonic transmitter so as to permit ultrasonic signals to pass out of the elongate aperture.Type: GrantFiled: December 20, 2017Date of Patent: October 1, 2019Assignee: ELLIPTIC LABORATORIES ASInventors: Ståle A Van Dorp Skogstad, Tom Kavli, Haakon Bryhni

Patent number: 9733720Abstract: An electronic device comprises an ultrasound transmitter, an ultrasound receiver, a display screen, and a processing system. It transmits ultrasonic signals from the ultrasound transmitter and receives ultrasound signals, through air, at the ultrasound receiver. It uses signals transmitted by the ultrasound transmitter and received at the ultrasound receiver to determine, at intervals, whether or not an object is present within a three-dimensional detection zone adjacent the device, by determining whether or not a set of presence conditions is met. It alters the display screen when the results of two successive such determinations differ. It also uses signals transmitted by the ultrasound transmitter and received at the ultrasound receiver to detect a movement of an input object, and control a further operation of the device in response to said detection.Type: GrantFiled: November 30, 2015Date of Patent: August 15, 2017Assignee: Elliptic Laboratories ASInventors: Tom Kavli, Thomas Børstad
