Abstract: A magnetic encoder comprising an encoder element having at least two tracks of encoder regions, each region comprising a magnetic pole, the poles along each track being arranged as an alternating pattern of North and South poles, and one or more sensors, each sensor comprising one or more sensing elements associated with a respective track and generating an output that is indicative of the magnetic field associated with that track in the vicinity of the sensor, in which at least one track has a differing number of poles to at least one of the other tracks, and in which the properties of the poles of a first one of the tracks differ along the track such that there is a periodic variation along the first track of the magnetic field emitted by the first track that is detected by the sensing elements associated with the first track which at least partially cancels out a corresponding periodic variation in field from the other tracks that is also detected by the sensing elements associated with the first track.

Abstract: A method for prognostic modeling includes obtaining probability values for possible health states of a system or component part using one or more data driven models and one or more physics of failure models. A probabilistic network is built using a plurality of observed and latent variables. The probable outcomes from the one or more physics of failure models and the one or more data driven models are combined to create an integrated model for failure prognosis. A health state of the system or system component is predicted using possible health states using the integrated model and the probabilistic network.

Abstract: A latch mechanism includes a chassis and a latch bolt movably mounted on the chassis. The chassis includes an abutment, and the latch bolt is moveable between an open position in which the latch bolt can receive a striker of a vehicle, a closed position at which the striker is capable of being retained by the latch bolt, and an over-travel position. The latch mechanism includes a buffer having a displacing element and an engagement portion. The buffer is capable of operably acting between the abutment and the latch bolt to absorb over-travel of the latch bolt. The displacing element is capable of moving frictionally against the engagement portion during over-travel to generate a frictional force to absorb over-travel energy of the latch bolt.
