摘要： A methods is provided for reliable and accurate detection of opening or closing of doors or drawers using output signals generated by a sensor, the output signals directly or indirectly representative of the acceleration of the sensor over time. Areas under a curve for acceleration, or representations thereof, are determined and occurrence of movement events identified through comparison of calculated areas with certain thresholds. Areas are considered which span between zero crossing points of the acceleration curve, such that all elements of the corresponding sum are of the same sign, and consequent area signals have maximal amplitude. Pairs of substantially equal and opposite area signals may be sought, occurring within a given time separation, these characteristic of an opening or closing motion, consisting of a first acceleration in a first direction followed by a second in an opposing direction. Apparatus for the reliable detection of opening or closing events is also provided.

摘要： Apparatus and associated methods relate to generating a frequency spectrum weighting function for use in estimating a rotational frequency of the rotating member. The estimation of the rotational frequency is based on vibrations sensed by an accelerometer remotely located from a rotating member. The frequency spectrum weighting function is generated by a supervised learning method. The method includes receiving a set of test vectors. The test vectors include a rotational frequency value of the rotating member and a vibrational frequency spectrum corresponding to vibrations propagated to the accelerometer. The vibrations include vibrations caused by the rotating member rotating at the rotational frequency. The method includes calculating a test weighting function, and then weighting the vibrational frequency spectra by the test weighting function. The method includes calculating a vector score indicative of whether the weighted vibrational frequency spectra promote the identification of the rotational frequency of the rotating member.

摘要： A method for detecting a failure of at least one sensor onboard an aircraft implementing a baro-inertial loop is provided. The method includes implementing a baro-inertial loop including obtaining a computed vertical speed, then a short-term baro-inertial altitude, based on a double integration of the measured vertical acceleration; and developing at least one intermediate loop parameter based on a deviation between the short-term baro-inertial altitude and the pressure altitude. The method also includes observing at least one failure detection parameter obtained from one of the intermediate parameters of the baro-inertial loop; and determining the presence of a failure on one of the sensors of the aircraft based on the value of the observed failure detection parameter.

摘要： A system estimates the speed of a moving vehicle and hence the driving behavior of an individual driving the vehicle using accelerometer data when GPS is intermittent, unavailable, or inaccurate. To do so, the system may first determine time periods when GPS data is not available. For each time period, the system may analyze the accelerometer data to find idling points when the vehicle is not moving. Based on the idling points, the system may divide each time period into segments. The system may then determine the speed of the vehicle at the boundary points of each segment. For each segment, the system may analyze the accelerometer data to determine the acceleration of the vehicle for points when the vehicle is moving. Subsequently, the system may calculate the speed of the vehicle for the points when the vehicle is moving based on the acceleration of the vehicle at those points and the speed of the vehicle at the boundary points.
