  • Patent number: 11929903
    Abstract: Some embodiments provide a novel method for assessing the suitability of network links for connecting compute nodes located at different geographic sites. The method of some embodiments identifies and analyzes sample packets from a set of flows exchanged between first and second compute sites that are connected through a first network link in order to identify attributes of the sampled packets. The method also computes attributes of predicted packets between the identified samples in order to identify attributes of each flow in the set of flows. The method then uses the identified and computed attributes of each flow in the set of flows to emulate the set of flows passing between the two compute sites through the second network link in order to assess whether a second network link should be used for future flows (e.g., future flows exchanged between the first and second compute sites).

  • Publication number: 20220226073
    Abstract: Devices, systems and methods for controlling motion of magnetic-driven nanobots are provided. Based on a selection indicative of a pattern of movement of the nanobots (200), a signal can be generated indicative of a pattern of magnetic field to be produced. Electrical signals can be generated to cause production of the pattern of magnetic field. The electrical signals can be provided to a device (300, 800) which is adaptable for being placed on the head or around a tooth of the patient. A first coil (502, 602, 804) of the device can receive the electrical signals and produce the pattern of the magnetic field to drive the magnetically-driven nanobots from a pulp region of the tooth into the dentinal tubules.

  • Patent number: 11295870
    Abstract: The present subject matter described herein relates to a Magnetically Augmented Plasmonic Tweezer (MAPT), a method for fabrication of the MAPT, and a method for trapping and maneuvering one or more colloidal particles inside a fluid. The fluid may correspond to a fluid inside a microfluidic device or a biological fluid. The MAPT can comprise a helical support structure to provide maneuverability in fluid. Further, a magnetic component is integrated in the MAPT for motion control. Plasmonic nanostructures are integrated in the MAPT for optical trapping of particles.

  • Patent number: 8768501
    Abstract: Methods and systems for the fabrication and application of Magnetically Actuated Propellers (MAPs) are described. MAPs are structures with typical feature sizes in the range of 20 nanometers up to 100 microns in one spatial dimension. MAPs are propellers that can be obtained from nano-structured surfaces and that can be produced in large numbers. MAPs are propelled and controlled by magnetic fields. The MAPs are optimized for low Reynolds number propulsion and can be moved in fluids and biological tissues. MAPs are useful for measurements, quantification, imaging and sensing purposes e.g. detecting biomolecules and for the controlled transportation of (drug- and bio-) molecules and the delivery of microscopic and nanoscale objects and/or materials or systems of therapeutic value. The MAPs are formed on a substrate and the released from the substrate using sonication, vibration, agitation, dissolution or etching which allows the MAPs to be produced in large numbers.

  • Patent number: 7961318
    Abstract: A system and method for detection and measurement of circular birefringences in materials that exhibit the Faraday effect. The method and apparatus permit detection of optical activities via the difference in the directions of propagation the left- and the right-circularly polarized light (components). A beam of light is directed at an interface formed by the optically active medium and another medium such that a difference in the angles of refraction and/or reflection and/or diffraction between the left- and the right-circularly polarized components of the light beam can be detected. The difference in the propagation directions between the two circularly polarized light components is measured on a position sensitive detector and/or is detected as an intensity difference.
