摘要： The present teachings relate to an electronic device comprising: a first module for generating an audio signal; a second module for generating an ultrasonic signal; a mixer for generating a combined signal; a transmitter for outputting an acoustic signal dependent upon the combined signal; and, a processing means for controlling the ultrasonic signal; wherein, in response to receiving a first instruction signal for initiating the ultrasonic signal, the processing means is configured to increase the amount of the ultrasonic signal in the combined signal from an essentially zero value to a predetermined value over a predetermined enable time-period. The present teachings also relate to an electronic device configured to decrease the amount of the ultrasonic signal in the combined signal from an essentially zero value to a predetermined value over a predetermined disable time-period, and to an electronic device configured to remove the audio signal from the combined signal whilst preventing pop-noise, and to an electronic device capable of replacing the ultrasonic signal whilst minimizing the processing time. The present teachings further relate to a method for reducing the occurrence of pop noise in an acoustic signal associated with: initiating the ultrasonic signal in the combined signal, terminating the ultrasonic signal in the combined signal, terminating the audio signal in the combined signal, and replacing the ultrasonic signal in the combined signal. The present teachings also relate to a computer software product for implementing any of the method steps disclosed herein, and to a computer storage medium storing the computer software herein disclosed.

摘要： An electronic device (202) includes an ultrasonic proximity sensor arrangement comprising an ultrasonic transmitter (4) and an ultrasonic receiver (6) recessed from a front surface (208) of the device. A barrier (218) extends between the transmitter and receiver in the direction of the front surface of the device. The ultrasonic proximity sensor arrangement is arranged to determine proximity of an object (16) to said front surface based on a signal (214) received by the ultrasonic receiver, wherein the received signal is a reflection from said object of a signal transmitted from the ultrasonic transmitter.

摘要： 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.

摘要： 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.

摘要： An electronic apparatus has a transmitter arranged to transmit an acoustic signal. It also has a receiver, for receiving acoustic energy comprising a reflection of the acoustic signal from an input object. It generates an electronic received signal from the received acoustic energy. The apparatus has processing means arranged to: (i) analyse at least a portion of the received signal to determine a linear combination of basis functions which represents an interference component in the received signal; (ii) use the determined linear combination to attenuate interference within the received signal, to give a post-attenuation signal; and (iii) use the post-attenuation signal to determine a user input to the electronic apparatus.
