Abstract: According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: obtaining a position of a user device; locating one or more surfaces providing one or more putative reflection points for a non-line-of-sight (NLOS) path between the user device and a wearable device; conditional upon locating the one or more surfaces, causing ranging signals to be exchanged between the user device and the wearable device to determine a relative position of the wearable device with respect to the user device; determining, from at least the relative position and position of the user device, data that enables calibration of one or more sensors of the wearable device; and causing transmission of the data to the wearable device.

Abstract: Examples of the disclosure relate to at least apparatus, methods, and computer programs, configured to control capture of two images of an area, across which a pulse propagates, using different shutter scanning directions. Either the images are converted into pulse-phase maps of the area and a pulse-phase difference map obtained which identifies differences between the pulse-phase maps of the area, or a colour difference map is obtained which identifies differences between the two images and the colour difference map is converted into a pulse-phase difference map. A shutter-time difference map is obtained which identifies differences between capture times of corresponding locations in the two images. Using the shutter-time difference map, the pulse-phase difference map is corrected to obtain a map of pulse-phase changes which have occurred over a duration of a shutter scan.

Abstract: An apparatus, method and computer program is disclosed. The apparatus may comprise means for receiving video data representing a video recording of at least one input made by a user at a user device; receiving audio data representing an audio recording of at least one audio input made by the user at the user device; determining whether there is a correspondence between the at least one input represented in the video data and the at least one audio input represented in the audio data; and providing verification based on the determination.

Abstract: Dust mitigation techniques are disclosed. An example apparatus includes a first component coupled in a movable relationship with a second component. The first component or the second component includes a recess accessible through an aperture. The apparatus also includes a brush disposed at the aperture and comprising fibers configured to prevent intrusion of dust into the recess. The apparatus also includes a vibration device configured to deliver a vibrational stimulus to the brush, wherein the vibration device activates a dust collection mode in response to a first movement of the first component relative to the second component and activates a dust shedding mode in response to a second movement of the first component relative to the second component.

Abstract: A method, apparatus and computer program product estimate the depth to objects within a scene that is captured by first and second cameras of a mobile terminal. A method includes determining, based upon an image including an eye of a user captured by a first camera of a mobile terminal and an image of a scene captured by a second camera of the mobile terminal, two or more angles of a geometric shape defined by the eye, the mobile terminal and an object of the scene.
