Abstract:
The invention relates to a method and a device for setting up a connection between two wireless low-power devices. The method for transponder aided wake-up and connection set-up of a low power radio device according to the present invention comprises at a device: detecting a wake up event, activating said device transmitting an advert message. Said method is characterized by and putting said low power radio device into a passive mode for a predetermined period of time, in case no answer in response to said at least one transmitted advert message is received. Thereby the present invention is integrating the good features of a time driven and event driven(1 approaches for transponder aided wake up. This results in that in sparsely populated areas the system can work as power efficiently as a pure event driven approach and in dense populated areas the system can work almost at as power efficiently as the pure time driven approach.
Abstract:
The invention relates to an authentication arrangement, which is based on a capacitive fingerprint sensor. The invention also relates to a manufacturing method of such a fingerprint sensor. One essential idea in implementing this invention is to fabricate a capacitive fingerprint sensor on a plastic substrate (363) with an embedded integrated circuit chip (380). The invention also describes a way to create two or three dimensional forms for electrode structures (321, 322, 325, 365, 366) that can be used to optimize the performance of the sensor. When the three dimensional structure is designed to follow the shape of a finger, a very small pressure is required when sliding the finger along the sensor surface. This way the use of the sensor is ergonomic and the measurement is made very reliable. The inventive fabrication method describes the way, how to connect and embed an integrated circuit containing measurements electronics with a batch processed larger scale electrode configuration that is used for capturing the capacitive image of the fingerprint.

The invention relates to a mobile electronic system. In order to expand and enhance the usability of the mobile electronic system, it is proposed that it comprises a 3D magnetometer (51) performing magnetic measurements in three dimensions and providing data indicative of the current posture of the mobile electronic system based on these measurements. Further, it is proposed that the mobile electronic system comprises processing means (52, 54) processing the data provided by the 3D magnetometer (51) for enabling a posture related presentation of information via output means (12, 42) of the mobile electronic system. The invention relates equally to components of such a system and to a corresponding method.

A system for managing physiological information includes a mobile terminal and at least one destination. The terminal is capable of transferring physiological information relating to a terminal user. The destination(s), in turn, are capable of receiving the physiological information and performing at least one operation based upon the physiological information. The destinations can return content to the terminal, where the content is selected based upon the operation(s) performed by the destination(s). Upon receiving the content, then, the terminal is also capable of performing at least one operation based upon the content. The system can also include a mobile station for facilitating the transfer of physiological information and content between the terminal and the destination(s).

Abstract:
An apparatus includes a deformable structure in which a neural network comprising a plurality of deformation sensors (8a, 8b), e.g. nanowire sensors, and distributed in-situ processing circuits (9a, 10a). The circuits generate a signal characterising features of the local deformation of the structure and/or a command signal corresponding to the detected deformation. The structure may be a wearable sleeve that conforms to deformations of a user's skin, part of an electronic device, such as a touch sensitive screen, or an object in itself. The apparatus can provide a user interface wherein a command corresponding to a current shape of the structure is generated and acted upon by a integrated or remote device, or a device for monitoring a user's position or movement e.g. for replication by a robotic device. The apparatus may have machine learning capability to improve the matching of commands with determined shapes of the deformable structure.
