摘要： A vessel having at least one hull, a body and a suspension system for supporting at least a portion of the body above the at least one hull is described. The suspension system includes at least one support means, and the vessel further includes at least one gyroscopic stabiliser for attenuating rotation of the body about at least one stabilising axis.

摘要： A position estimate for a mobile device is generated using data from motion sensors, such as accelerometers, magnetometers, and/or gyroscopes, and data from light sensors, such as an ambient light sensor, proximity sensor and/or camera intensity sensor. A plurality of proposed positions with associated likelihoods is generated by analyzing information from the motion sensors and a list of candidate positions is produced based on information from the light sensors. At least one of the plurality of proposed positions is eliminated using the list of candidate positions and a position estimate for the mobile device is determined based on the remaining proposed positions and associated likelihoods. The proposed positions may be generated by extracting features from the information from the motion sensors and using models to generate likelihoods for the proposed positions. The likelihoods may be filtered over time. Additionally, a confidence metric may be generated for the estimated position.

摘要： A gyroscopic device of the type having a short-circuited rotor winding or conductor (10) so shaped so as to produce axial and radial flux components when rotated in the earth's magnetic field is coupled to a coaxial sensing coil (15) coaxial which gyroscopically stabilized thereby, signals induced in the sensing coil due to the axial flux component of the rotor is used to derive magnetic heading information and there is provided at least one further coil (41) on the supporting body and inductively linked to the sensing coil and rotor such that when the sensing coil is gyroscopically stabilized by the rotor, the coil supported on the supporting body in relation to the gyroscopically stabilized sensing coil is such that any changes in angular orientation of the supporting body relative to the gyroscopically stabilized sensing coil introduces changes in the signal voltages induced in the coils. The further coil on the supporting body may be excited with one or more excitation signals of a frequency different than the angular speed of the rotor (10) and constituted by pairs of orthogonally related coils on all three axes namely, the roll (41, 42), pitch (43, 44) and yaw (45, 46) axes. The coil located on the yaw axis is coaxial with the gyroscopically stabilized sensing coil in the rest position and is used for eliminating ambiguities.
