摘要:
A method and device for detecting the presence of a deception scheme intended to thwart a satellite navigation system (SNS). A detector receives “receiver measurements” of various types from the SNS receiver. It conditions these values, so that they may be readily used by a process that determines whether the receiver is operating in a statistically normal state.

In at least one embodiment, a system and method provides a paradigm shift in generating a medical record by allowing a clinician increased flexibility in documenting a patient examination and treatment while still generating a structured medical record that facilitates multiple, subsequent processing options. In at least one embodiment, the system and method utilize natural language processing and feedback to generate a complete, electronic medical record.

A method and system for reconstructing random samples taken across multiple sensors of a sensor array, so that each sensor's output is reconstructed. The samples are processed using a compressive sensing process. The compressive sensing process uses a time-space transform basis that represents the multi-channel data in terms of both a frequency component and an azimuthal component.

A friction stir welding device operable to weld a joint formed between a first workpiece and a second workpiece. The friction stir welding device includes a clamping device coupled to a tool body of the welding device for movement with the tool body along the joint. The clamping device includes a first guide member and a second guide member. The first guide member includes a clamping face configured to engage the first workpiece and the second guide member includes a clamping face configured to engage the second workpiece. The clamping face of the first guide member is directly opposed to the clamping face of the second guide member to resist separation of the joint.

A method or system for detecting associations between nodes of a communications network. “Node events”are defined as being communications from one node to another, each event having an origination time. For a given node, and for a number of time windows, event originations from other nodes after the occurrence of an event from that node are counted. Then for that node, these counts may be used to determine the probability that any other node is in a time window of that node. The probability data may then be used to determine the likelihood of a communications link with that node. The process may be repeated for a number of nodes to determine links within the network.

Embodiments of the invention relate to a cable force feedforward approach that takes into account the cable force in the counter-mass trajectory computation to reduce or eliminate vibration of the lens body caused by the cable force disturbance and corrective force exerted by the trim motors. In one embodiment, a method provides cable force feedforward control for a counter-mass of a stage with a cable connected to the counter-mass and using the cable force feedforward control to control one or more trim motors to produce a trim motor output force to be applied to the counter-mass, the counter-mass moving in response to a reaction force from movement of the stage. The method comprises measuring a counter-mass position y of the counter-mass in response to forces applied to the counter-mass; measuring a cable force ƒ exerted on the counter-mass by the cable which is connected to the counter-mass; generating a cable force function {circumflex over (ƒ)}(y, {dot over (y)}) of the measured cable force ƒ versus the counter-mass position y; and computing the trim motor output force u as u ≅ - f + w · f ^ ( y , y . ) , where w is a weighting function having a value from 0 to 1 and is selected for optimization.
