Abstract: An embolic protection system having a guidewire for advancing through a vasculature; an embolic protection filter having a filter body with a distal end and a proximal end, the filter body providing for a collapsed configuration and an expanded deployed configuration. The embolic protection filter body has a guidewire path for slidably receiving the guidewire to permit movement of the filter relative to the guidewire when the filter 1 is in the collapsed configuration and the expanded deployed configuration. A delivery catheter is advanceable over the guidewire for delivery of the embolic protection filter. A retrieval catheter is also advancable over the guidewire for retrieval of the filter, and engagement elements are used for engaging the embolic protection filter with the guidewire for retrieval of the filter into the retrieval catheter in the collapsed configuration.

Abstract: Methods and systems for detecting GNSS signals originating from an inauthentic source. A synthetic array using a receiver antenna which is randomly spatially translated may be used to gather alleged GNSS signals. The signals are then processed to determine the spatial correlation between them. A high spatial correlation between the signals indicates a probable inauthentic source for the GNSS signals.

Abstract: A system for estimating parameters of an incoming signal is provided. At least one antenna is coupled to at least one suitable receiver. The antenna(s) are spatially translated in an arbitrary trajectory. As the antenna(s) is being spatially translated, a data processing means samples the incoming signal at set intervals based on a clock signal provided by a system clock. By sampling the incoming signal at different times at different spatial locations on the arbitrary trajectory, the system acts as a synthetic antenna array. The different samplings of the incoming signal at different times and positions provide signal diversity gain as well as different readings which can be used to estimate and/or calculate various parameters of the incoming signal. The different samplings can be used to detect the incoming signal, estimate its angle of arrival, estimate its time of arrival, as well as other parameters.

Abstract: Systems and methods related to the detection of incoming wireless signals. An antenna array is synthesized by having a single antenna, coupled to a receiver, spatially translated along an arbitrary trajectory. As the antenna is being spatially translated, a data processing means samples the incoming signal based on a clock signal provided by a system clock. By sampling the incoming signal at different times at different spatial locations on the arbitrary trajectory, the system acts as a synthetic antenna array. The different samplings of the incoming signal at different times and positions provide signal diversity gain as well as different readings which can be used to detect an incoming signal. The invention is applicable to detecting a wireless communications signal or a GNSS signal under various conditions. The system may include at least one sensor which can provide data for use in calculating data related to the arbitrary trajectory.

Abstract: Endodontic instruments or intermediate products (e.g., blanks) used to form finished endodontic instruments having a desired cutting edge and/or taper are formed, at least in part, by molding a metal powder into a desired shape and then sintering the metal particles together. The metal powder is initially formed into a green molded part that is sintered to yield a solid metal part. The sintered metal part may optionally be further processed by additional steps, as needed, to yield a finished endodontic instrument. One additional process includes cold forming the sintered metal body to provide a cutting edge, remove cracks and microfissures, or otherwise modify the characteristics of an intermediate product or endodontic instrument. Other processes include chemical milling and mechanical milling, grinding or cutting to sharpen the cutting edge, form a taper, or otherwise modify the intermediate product or endodontic instrument in a desired manner.

Abstract: Endodontic instruments having a desired cutting edge are formed, at least in part, using a cold forming process. The method of forming the endodontic instrument includes providing a blank metal thread or wire and at least one die that has a negative impression of a cutting edge. The die is pressed against the blank with sufficient force in order for the die to form an at least partially formed cutting edge in the blank. Any desired shape can be formed into the blank by selecting a die with the proper corresponding negative impression. Cold forming techniques suitable for forming endodontic instruments include roll forming, flat rolling, radial forming, cold drawing, and similar techniques. The files can be sharpened or otherwise modified before or after cold-forming using techniques such as cutting, grinding, and chemical milling.

Abstract: The present invention relates to a method and an apparatus for controlling a power-grid connected wind turbine generator during grid faults. During grid faults, the stator windings of the wind turbine generator are disconnected from the power grid and impedances for dissipating at least part of the power generated by the wind turbine during grid fault condition are connected to the stator windings. In this way, a certain magnetisation of the generator can be maintained and after removal of the grid fault condition, the generator is synchronised to the power grid and the impedances are disconnected and the stator windings are reconnected to the power grid. In this way, it is possible to keep the wind turbine generator at least partly magnetised during grid faults and thus ready for delivering power to the power grid, as soon as the grid voltage is re-established after the fault.
