An observer device () listens for advertising messages from broadcast devices () in an environment, transmits scan request messages to broadcast devices, and subsequently receives scan response messages. The observer device () can connect to a broadcast device () and configure the broadcast device () to a scanning mode. The broadcast device () selected for scanning listens for advertising messages from other broadcast devices (). The broadcast device () relays information related to these other broadcast devices () back to the observer device ().

Method and apparatus for searching and relaying discovery of devices

A device determines the positioning of objects in a scene by implementing a robust and deterministic method. The device obtains object detection data (ODD) which identifies the objects and locations of reference points of the objects in views of the scene. The obtained ODD is processed to identify a first image object of a first view as a mirror reflection of a real object. A virtual view associated with a virtual camera position is created, including the ODD associated with the first image object of the first view. The ODD associated with the first image object is removed from the first view. Based on the ODD associated with at least said virtual view and a further view of the one or more views, a position of said first image object is computed.

Multi-view positioning using reflections

A method for controlling upload of data, performed in an electronic device (), wherein said electronic device is configured to intermittently upload data () to a wireless network to operate as a tracker, said method comprising: obtaining () a current position of the electronic device, determining, dependent on network coverage associated with said position, to either upload data () to the network or postpone () upload of data.

Power saving for device tracking

A system and method are provided for controlling the own-voice experience of a user who talks while an earpiece is mounted to occlude an ear of the user. A vibration sensor is engaged with the user's head to sense vibrations formed by the user speaking and conducted by the user's head to the vibration sensor. A signal generator operates a speaker element, which is integrated with the earpiece, to generate sound waves in the ear canal of the user, based on the output signal of the vibration sensor. The signal generator generates the sound waves to at least partially cancel other sound waves that are generated by at least part of said vibrations entering the ear canal from surrounding bone and/or tissue. The system and method counteracts the occlusion effect and are applicable in connection with in-ear headsets, earphones, in-ear headphones, in-ear monitors, circumaural headphones, hearing aids, earplugs and earmuffs.

Controlling own-voice experience of talker with occluded ear

The invention is directed to determining a gain for an equalizer associated with an audio device. An exemplary method comprises determining a maximum audio output level allowed by an acoustic safety threshold; determining a setting of the equalizer; and adjusting a gain of the equalizer based on the setting and the maximum audio output level. The invention enables an audio device to simultaneously satisfy an acoustic safety threshold and deliver an optimum audio output level.

Gain optimized equalizer

A method for reducing crosstalk in a headset connected to an audio device, in which the includes a left headphone, a right headphone and a common ground for the left headphone and the right headphone includes determining a frequency dependent impedance of the headset. The method also includes determining a frequency dependent impedance of the common ground, and determining a frequency dependent substantially optimum cross feed for attenuating crosstalk in at least one of the left headphone and the right headphone based on the impedance of the headset and the frequency dependent impedance of the common ground. The method further includes applying the frequency dependent substantially optimum cross feed to attenuate the crosstalk in the at least one of the left headphone and the right headphone.

Crosstalk reduction in a headset

An electronic device includes a force sensor that is configured to generate a force signal that indicates an amount of force being exerted thereon by a user, and a controller circuit that is configured to control a volume and/or rate that an audio signal is broadcast by a speaker responsive to the force signal.

Regulation of audio volume and/or rate responsive to user applied pressure and related methods

The present invention provides an earphone comprising an electro-active polymer that is adapted such that the outer circumference of a resilient member of the earphone is responsive to an electric voltage, enabling providing essentially sealing the ear canal when the resilient member of the earphone at least partly is inserted in an ear canal of a wearer. The electro-active polymer also enables an improved game and sound experience by providing by synchronizing the outer circumference of the resilient member with the electric signal provided to the earphone.
