  • Patent number: 10977776
    Abstract: A method includes placing an imaging device in contact with a sample, irradiating the sample via an illuminator such that radiation scatters off of the structure, and providing the scattered radiation to a detector to generate a digital video signal. A processor then performs various operations including subtracting a sum of a black state value and a user-defined black level clamping value from the digital video signal to create subtracted image data, substituting negative values in the subtracted image data with a reference value to create modified image data, and amplifying the modified image data by a user-defined gain to create contrast enhanced image data.

  • Patent number: 10954152
    Abstract: A supercritical water oxidation-flame piloted vortex reactor has a hydrothermal flame produced within the interior of the reactor fed by a fuel including a waste water stream, and has a subcritical wash stream, including water below its critical point, that creates an upward helical flow in the material within the reactor. The hydrothermal flame and upward helical flow produce within the reactor a supercritical core region, a subcritical outer region around the core region, and a transcritical intermediate region between them. The upward helical flow serves to transfer precipitated ionic compounds out of the supercritical core region, through the transcritical intermediate region, and into the subcritical outer region where they re-dissolve. A processed flow, including purified water, is removed from an upper portion of the supercritical core region by an aspirator.

  • Patent number: 10888487
    Abstract: A grasp assist system includes a glove having a glove palm and fingers, with the glove worn on a user's hand. A sensor measures flexion of the glove fingers, and thus a change of position and/or attitude of the fingers is determined. Finger saddles at least partially surround a phalange of a respective one of the user's fingers. The system uses one or more tendon actuators to pull on flexible tendons. Each tendon connects to a respective finger saddle. A controller is in communication with the actuators and sensor(s). The glove may use feedback from optional contact sensors to adjust tension, and may have a built-in restorative force. In executing a control method, the controller selectively applies tension to the tendons in response to finger flexion, via the tendon actuators, at a level sufficient for moving the user's fingers when the user executes a hand maneuver.
