Abstract: A two-filter based method of detecting and tracking a target that can track an unknown and time-varying number of targets, while keeping continuous track, even in scenarios with large number of false contacts or missing measurements, is provided. More specifically, a first filter provides target detection, a second filter provides target tracking of the detected targets, and a clustering technique that operates after the first filter. The first filter starts with a uniform distribution over the surveillance area and resets periodically after the clustering technique is run. When the clustering technique runs, it detects the clusters corresponding to the different targets and passes them to the second filter that tracks these targets.

Various embodiments function on the principle that it is highly unlikely that the observed magnetic field will be the same in any two given locations (at least, when the observed magnetic field is measured in three dimensions), and moreover, it is unlikely that the observed magnetic field will change if the device remains stationary.

The device can be configured to periodically check its current reading of the observed magnetic field. If the device determines that its magnetic reading has changed relative to its last reading, a possible or actual relocation event can then be declared.

Abstract: An audio processing system processes an audio signal that may come from one or more microphones. The audio processing system may use information from one or more non-acoustic sensors to improve a variety of system characteristics, including responsiveness and quality.

Using the non-acoustic sensor information may decrease this susceptibility advantageously in an audio processing system.

Abstract: A system and method for more accurately and robustly determining the heading of a vehicle by taking measurements of angle rates using rate sensors mounted on a movable mechanical assembly. In a quasi-static state of the vehicle, the mechanical assembly is rotated around axes perpendicular to the tangent plane of the Earth, and angle rates are measured by the rate sensors at different rotational angles of the mechanical assembly. The measurements of the angle rates are then computed to determine the initial heading of the vehicle relative to the true north of the Earth in the quasi-static state of the vehicle. After determining the initial heading, navigation state propagation is performed to determine the heading of the vehicle in non-quasi-static state of the vehicle. By taking measurements of the rate sensors at different rotation angles and performing computation, the heading of the vehicle relative to the Earth's true north can be determined using less accurate angle sensors.

Abstract: A projectile, such as a missile, rolls during at least a portion of its flight, while retaining its roll reference to enable navigation during the rolling period of flight. The roll reference may be retained by using a sensor, such as magnetometer, to periodically check and correct the roll reference. Alternatively or in addition the missile may alternate roll directions, for example varying roll rate in a substantially sinusoidal function. By rolling the missile inaccuracies in an inertial measurement unit (IMU) of the missile may be ameliorated by being to a large extent canceled out by the changes in orientation of the missile as the missile rolls. This enables use of IMUs with lower accuracy than would otherwise be required to obtain accurate flight. Thus accurate flight may be accomplished with less costly IMUs, without sacrificing the ability to navigate.

Yet another method maintains overall system functionality in a system with multiple distance sensors in the event that one or more of the distance sensors fails. The robotic system may also determine when maintenance is required.
