Abstract: A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.

Abstract: A tool assembly for friction extrusion can comprise a friction extrusion die. The friction extrusion die can include a distal face and a proximal end. The distal face can define at least one topographical ridge or groove feature to induce plasticization of a material in response to an axial force and a rotational force applied by the distal face to the material. The friction extrusion die can define a central passage to carry an extrudate of the material in a proximal direction in response to the applied axial and rotational forces. The proximal end can define a faceted cross-sectional profile to mate a with a corresponding receiving end of a tool holder. The faceted cross-sectional profile can be sized and shaped to receive the rotational force through engagement by the tool holder of respective faces defined by the faceted cross-sectional profile.

Abstract: A fluid vapor distillation system. The system includes a control system for controlling a fluid vapor distillation apparatus including a blow down controller for controlling a blow down valve, a source flow controller for controlling a source flow valve, and a blow down level sensor in communication with a blow down controller and a source flow controller, the blow down level sensor sends signals related to the blow down level to the blow down controller and the source flow controller indicative of the blow down level, wherein the source flow controller actuates the source flow valve based at least on the blow down level sensor signals, and wherein the blow down controller actuates the blow down valve based at least on the blow down level sensor signals, whereby the blow down level and the source flow level are maintained using the blow down level sensor signals as input.

Abstract: A system for locating a patient's veins includes an illuminator configured to emit a conical beam for illuminating a target area of the patient and contrast between veins and surrounding tissue. The illuminator can be a short-wave infrared (SWIR) laser with a lens optic coupled to the SWIR laser for shaping the beam into a conical profile. The illuminator can be a visible light source with a reflective optic coupled to a filter configured to allow SWIR wavelengths therethrough.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: In at least one embodiment, an automated medical data machine learning system and method allow a natural language processing (“NLP”) system to automatically learn via, for example, feedback to improve ongoing performance of the natural language processing system. The particular technology for improving the interpretation by the NLP system of future input data is a matter of design choice. In at least one embodiment, the automated medical data learning system and method includes a linguistics module that determines the part of speech of a particular term or term, such as use as a noun or verb. In at least one embodiment, the system and method learns an interpretation based on a source of the input data. In at least one embodiment, the system and method includes a statistics module that allows the system and method to determine a most probable interpretation or multiple interpretations.

Abstract: 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.

Abstract: 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.

Abstract: 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.
