  • Patent number: 10416478
    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.

  • Publication number: 20190271757
    Abstract: A method performed in a server node associated with a cellular communication system is disclosed. The method is for validation of a first position indication of a wireless communication device, wherein the wireless communication device is adapted to operate in connection with the cellular communication system. The first position indication is obtained via the wireless communication device by a first positioning system. The method comprises obtaining a serving cell identification of the wireless communication device, obtaining a second position indication of the wireless communication device based on the serving cell identification, and determining whether the first position indication is valid based on whether a metric based on the first and second position indications meets a validation criterion.

  • Publication number: 20190272364
    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.

  • Publication number: 20190206204
    Abstract: It is presented a method for encoding haptic data for a plurality of channels. The method comprises the steps of: determining an order of the plurality of channels in a first list based on a respective previous codeword data item for each of the plurality of channels, each previous codeword data item being either a no-change data item, or a change data item, wherein the order is such that all no-change previous codeword data items are arranged at one end of the first list; arranging current codewords in a second list accordance with the channel order of the first list; grouping the current codewords in consecutive groups; generating a group index indicating whether each group contains only no-change codewords or at least one change codeword; and outputting the group index along with current codewords, wherein current codewords are only output for groups containing at least one change codeword.

  • Publication number: 20190184565
    Abstract: When a control message is determined and sent from a master system to a slave system, the control message is accompanied with a time stamp, indicative of the master model version of the environment which was applied when the control data was determined by the master system. When data, triggered by data provided from the environment to the slave system in the form of updated sensor data is provided from the slave system to the master system, also that data, indicative of an updated slave model version of the environment made by the slave system, is provided to the master system, together with a time stamp, indicative of when the update of the slave model version was made. By applying the suggested time stamp, a coordination of model versions can be obtained between the master system and the slave system.

  • Publication number: 20190149323
    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.

  • Patent number: 10268235
    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.
