Abstract: A communications device for generating a key for use as a shared secret in communications with another communications device. Each communications device comprises a sensor array for measuring a spatially-varying magnetic field originating from a first spatially-varying density of metallic particles comprised in a first battery, when subjected to an excitation magnetic field, and processing means operative to acquire a set of values from the sensor array, which set of values represents the spatially-varying magnetic field, and to derive the key from the set of values. The excitation magnetic field is generated by a magnetic-field generator comprised in one of the communications devices. Thereby, the two communications devices may, when in proximity, generate identical keys by probing the spatially-varying density of metallic particles comprised in the first battery.

Abstract: An imaging device comprising a first camera with a controllable focus is provided. The imaging device is operative to detect that a user of the imaging device intends to capture an image of an object using the first camera, control the focus of the first camera to assume a target focal length, and capture the image. The target focal length is derived based on a measured accommodation of an eye lens of the user. Further, a contact lens comprising an eye-accommodation detector and a communications module is provided. The contact lens is operative to measure an accommodation of an eye lens to which the contact lens is attached, and transmit, to an imaging device comprising a first camera with a controllable focus, information pertaining to the measured accommodation of the eye lens and/or a focal length of the eye lens corresponding to the measured accommodation.

Abstract: A computing device for authenticating a user is provided. The computing device is operative to display a first text to the user, acquire a representation of the user subvocalizing a part of the first text, derive a user phrasing signature from the acquired representation, and authenticate the user in response to determining that the user phrasing signature and a reference phrasing signature fulfill a similarity condition. Optionally, the computing device may be further operative to determine if the user is authorized to read the first text. Further optionally, the computing device may be operative to reveal obfuscated parts of the first text in response to determining that the user is authorized to read the first text, or to discontinue displaying the first text, or to obfuscate at least part of the first text, in response to determining that the user is not authorized to read the first text.

Abstract: A device for controlling a lens for adjustable vision correction is provided. The device, e.g., a smartphone, comprises circuits to determine if a user of the device is gazing at the device, and, if the user is gazing at the device, to determine a distance between the eye and the device, and to control the lens to adjust its focal length based on the determined distance. Thereby, the lens is adjusted only if required, i.e., if the user is gazing at the device. The circuits may be suitable for correcting presbyopia if the user is gazing at a device located at close distance, and alleviate the need for the user to actively operate a switch or move her head for adjusting the focal length of her lenses.

Abstract: A computing device (300) for authenticating a user (110), such as a mobile phone, a smartphone, a tablet, or the like, is provided. The computing device is operative to acquire a representation of a melody generated by the user, and authenticate the user in response to determining that the acquired representation of the user-generated melody and a representation of a reference melody fulfil a similarity condition. The user-generated melody may either be vocalized or subvocalized. If the melody is vocalized, the representation is derived from audio data captured by a microphone (102). If the melody is subvocalized, the representation is derived from nerve signals captured by sensors attached to the throat (111) of the user, or from a video sequence acquired from a camera (103), the video sequence capturing one or more body parts (111-115) of the user subvocalizing the melody, by magnifying motions of the one or more body parts which are correlated with the subvocalized melody.

Abstract: A user-worn device (100) comprising an ultrasonic transducer configured for contacting a first body-part (116), e.g., a wrist, of a user and a touch-device (250) comprising an ultrasonic transducer (201) configured for contacting a second body-part (112), e.g., a finger, of the user are provided. The ultrasonic transducer comprised in the user-worn device (100) is further configured for transmitting data between the user-worn device (100) and the touch-device (250) encoded in ultrasound (121) via the second body-part (112). The user-worn device (100) is operative to receive, from the touch-device (250), an indication identifying data to be transmitted to the touch-device, select data for transmission to the touch-device (250) based on the received indication, and transmit the selected data to the touch-device (250).

Abstract: A device (100) for handheld operation, such as a mobile phone, a mobile terminal, a smartphone, a User Equipment (UE), a tablet, a phablet, a media player, a remote control, or a gaming console, is provided. The device is operative to detect an imminent or prevailing indication of an unstable operation of the device when being held by a hand (110) of a user of the device, and, in response thereto, to increase a grip between an outer surface (101, 103) of the device and one or more fingers (111-114) of the hand. The grip may, e.g., be increased by generating an adhesive force, or by increasing a friction, between the outer surface and the one or more fingers. Thereby, the risk for the user dropping the device is reduced, and a more convenient operation of the device is achieved, in particularly if operated single-handedly.

Abstract: An image capturing device is provided comprising an image sensor for capturing a first image of a scene, a light source for illuminating the scene with a first flash of coded light, and a network interface for communicating with a communications network and/or a further image capturing device. The device is operative to encode information into the first flash, enabling retrieval of the first image from a first data storage, capture the first image, and store the first image in the first data storage. Optionally, the device may be operative to detect a second flash of coded light emitted by the further image capturing device, decode information enabling retrieval of a second image captured by the further image capturing device from a second data storage, retrieve the second image, and create a 3D model from the first image and the second image.

Abstract: An apparatus that helps a user grasp a hand-held device (10) resting on an underlying surface (S) detects when the user is reaching for the hand-held device. In response to the detection, the apparatus performs an action that elevates at least a part of the hand-held device above the underlying surface. Elevating the hand-held device above the underlying surface allows the user to grasp and lift the hand-held device off of the underlying surface more easily.

Abstract: A device (100) for handheld operation is provided. The device comprises a touchscreen (110) and processing means (111) operative to display a plurality of user-interface (UI) elements (121-124) on the touchscreen, wherein each UI element is associated with an action which is performed in response to touching the UI element, determine one or more of the displayed UI elements which a user (150, 151) of the device is likely to touch based on a touch pattern (130), and perform, for at least one of the determined UI elements, the action associated with the UI element. The action may, e.g., comprise pre-fetching content which is likely to be requested by the user from a server (180). Performing an action, such as pre-fetching, based on a touch pattern is advantageous since a touch pattern reflects the relative likelihood that the user touches a specific position, or region, of the touchscreen, thereby reducing latency.

Abstract: The present disclosure relates to virtualizing a network function in an ad-hoc group. The ad-hoc group comprises a plurality of mobile terminals (302, 304) that are configured for device-to-device communication, e.g., Proximity-Based Services (ProSe). The Pro Se-enabled mobile terminals (302, 304) subscribe to a Network Functions Virtualization (NFV) service with an NFV management server (322). The NFV management server (322) discovers the ad-hoc group that is suitable for NFV and informs an NFV application server (324) of the ad-hoc group.
