This application relies on terminology found in the Vehicle State Detection (STATE) patent and describes methods of detecting acceleration, deceleration, accidents and cornering operational states, which we will also call vehicle dependent states, and vehicle independent states, triggered when the portable device is moved independently of movement of the vehicle. These methods enhance classification of driving behavior.

A movement sensor comprises a multi-pole ring magnet, a semiconductor substrate, a first magnetic sensor formed on the semiconductor substrate, and a second magnetic sensor formed on the semiconductor substrate. The first magnetic sensor is configured to produce a first output signal in response to movement of the multi-pole ring magnet, and a centroid of the first and second magnetic sensors are separate and radially aligned on the semiconductor substrate relative to the multi-pole ring magnet. The second magnetic sensor is arranged at a predetermined angle with respect to the first magnetic sensor and is configured to produce a second output signal in response to the movement of the multi-pole ring magnet. The predetermined angle is between 0° and 90° exclusive and is configured to produce a difference in phase between the first and second output signals in response to the movement of the multi-pole ring magnet.

Disclosed is a method of correcting at least one result of calculating at least one flight characteristic of an airplane, based on in-flight measurements and on values calculated from the measurements, the in-flight measurements being taken in at least one determined flight condition defining a determined flight point, each flight condition being defined by particular flight parameter values, the measurements and values being in particular: θ.sub.measure the measured pitch angle of the airplane and α.sub.model the angle of attack calculated by solving a lift equation and an aerodynamic model associating the angle of attack α of the airplane with at least one flight parameter, which is the lift coefficient Cz of the airplane. The pitch angle measurements θ.sub.measure are corrected by a pitch angle correction term Δθ.sub.0 that is a particular constant for each flight, and the calculated angles of attack α.sub.model are corrected by an angle of attack correction term Δα(Cz . . . ).

According to the present invention, on the basis of the detected surrounding situation the movement of object bodies in the surrounding area is predicted as a future situation in the surrounding area. Candidates of direction from which a moving direction to be shown to the user is determined are extracted on the basis of the predicted future situation in the surrounding area. The extracted candidates are evaluated for movement easiness of the user in the surrounding area on the basis of the predicted future situation in the surrounding area and the detected situation of the user. Then, the moving direction to be shown to the user is determined on the basis of the evaluation and the extracted candidates. A direction corresponding to the determined moving direction is shown to the user in front of the user.

Embodiments of the present disclosure provide improved user interface(s) that intuitively convey information via a dynamic wind indicator. Embodiments include a dynamic wind indicator that is specially configured to visually indicate data value(s) via one or more visual properties of the dynamic wind indicator. As updated data is received, the dynamic wind indicator is updated in real-time to visually indicate the most up-to-date data value(s), for example to intuitively visually indicate effects of wind on an aerial vehicle. Some example embodiments receive wind movement data including wind speed data and wind directionality data. Some such example embodiments cause rendering of a user interface including a dynamic wind indicator that [1] visually indicates a direction of a 3D environment based on the wind directionality data, and [2] has at least one visual property configured based on the wind speed data.
