    Abstract: A medical device includes an elongate body and an inflatable balloon attached to and partially surrounding at least a section of the elongate body. The inflatable balloon is selectively inflatable between a deflated state and an inflated state. Engagement between the balloon and a physiological lumen is provided, in part, by multiple protrusions extending from the inflatable balloon and having various physical and functional characteristics. In certain implementations, the balloon may be configured to exhibit various separation forces by applying different strains to the balloon, such as by varying the degree to which the balloon is inflated or deflated.

    Abstract: Various embodiments of the present technology generally relate to robotics and prosthetics. More specifically, some embodiments of the present technology relate to multi-modal fingertip sensors with proximity, contact, and for localization capabilities. Various embodiments of the present technology provide for a novel multi-modal tactile sensor which comprises an infrared proximity sensor and a barometric pressure sensor embedded in an elastomer layer. Signals from both of these sensors can be fused to measure proximity (0-10 mm), contact (0N), force (0-50N) and localize impact at five spatial locations and three angles of incidence. Gaussian processes in a regression setting can be used to obtain calibrated force measurements with an R-squared value of 0.99. Supervised machine learning approaches can be used to localize the position and direction of probing with classification accuracies of 96% and 89% respectively.

    Abstract: Various embodiments of the present technology generally relate to devices and methods for generating and directing energetic electrons toward a target. More specifically, some embodiments relate to devices, systems, and methods for generating and directing energetic electrons based in the photoelectric effect and directing electric field-focused beams of the energetic electrons toward a target. Electron guns according to the present technology include one or more light sources to stimulate electron transmission, and a series of differentially charged stages to provide a hollow path allowing electrons generated by the photoelectric effect of the light irradiated on interior surfaces defining the path through the stages to travel to an exit of the electron gun. Each of the differentially charged stages have a different potential, thereby providing electrons having two or more different and tunable energy levels exiting as a beam from the electron gun.

    Abstract: One aspect of the invention provides a device for passive detection of the presence of a drone. The device includes: an antenna; a receiver in communication with the antenna to passively receive wireless signals; and a processor in communication with the receiver and programmed to determine whether a drone is present based on a pattern in the wireless signals emitted from the drone that is correlated with a physical movement of the drone. Another aspect of the invention provides a method for passively detecting the presence of a drone. The method includes: receiving a wireless signal at a device comprising an antenna, a receiver and a processor; and analyzing the wireless signal to determine whether the wireless signal includes a pattern in the signal that is indicative of a physical movement of a drone.
