Abstract: A six-degree-of-freedom (6DOF) tracking system adapts aspects of Ultra-Wideband (UWB) measurement and microelectromechanical systems (MEMS) inertial measurements within a unique tightly coupled fusion algorithm to accurately and efficiently measure an object's position as well as orientation. The principle of operation of the system protects against the negative effects of multipath phenomenon and non-line-of-sight (NLOS) conditions, allowing a more robust position and orientation tracking system.

Abstract: A cryptographic calculation is carried out in an electronic component according to a specific cryptographic algorithm including at least one specified non-linear operation on blocks of data of k bits, k being a whole number of more than 2. Several blocks of masked intermediate data of j bits are generated from an initial block of data of k bits, j being a whole number that is smaller than k. Then a non-linear operation S is applied to at least one of the masked intermediate data blocks of j bits with the aid of a substitution table with 2 inputs producing a modified data block of j bits. The modified data block of j bits and at least some of the masked intermediate data blocks of j bits are combined to form a result block of k bits corresponding to the initial data block of k bits by means of a transformation including the specified non linear operation.

Abstract: A system is provided for capturing motion of a moving object via a plurality of motion sensor modules placed on various body segments. The sensor modules capture both 3D position and 3D orientation data relating to their respective body segments, thereby gathering motion data having six degrees of freedom with respect to a coordinate system not fixed to the body. Each body sensor collects 3D inertial sensor data and, optionally, magnetic field data. In embodiments, either DSP circuitry within the sensor modules or an external computing device, processes the sensor data to arrive at orientation and position estimates by using an estimation algorithm, such as a Kalman filter or a particle filter. The processing includes biomechanical model constraints that allow flexibility in the joints and provide characteristics for various joint types. To improve estimation accuracy, the system may be integrated with various types of aiding sensors.
