Abstract: Apparatus, method and SW for 3D face recognition. The method includes: processing a plurality of initial registrations, each initial registration made by a user, stored in a storage, and including a registration facial image taken with a user apparatus; receiving a current three-dimensional facial image of a current user taken with an authorized three-dimensional camera; searching the plurality of registration facial images for a match with the current three-dimensional facial image based on selected facial features; and if a registration facial image matching with the current three-dimensional facial image is found, confirming the initial registration having the matching registration facial image, and replacing the registration facial image with the current three-dimensional facial image in the storage.

Abstract: Relevance determination of sensor event is disclosed. An apparatus obtains a sensor event created on the basis of sensor data generated by one or more sensors, determines relevance of the sensor event, and if the relevance of the sensor event fulfills a predetermined relevance condition, outputs, with the output interface, the sensor event according to its determined relevance.

Abstract: Adjustment of sensor measurement and transmission intervals in a mobile apparatus is disclosed. The mobile apparatus obtains sensor data from the one or more sensors, and obtains wireless data with the wireless transceiver. Furthermore, the mobile apparatus adjusts repeatedly a measurement interval of the one or more sensors for obtaining the sensor data and a transmission interval of the wireless transceiver for transmitting the sensor data on the basis of the obtained sensor data and the obtained wireless data.
