Abstract: An articulating, steerable surgical probe includes an elongated, flexible transfer tube adapted for insertion into a surgical region for endoscopic laryngeal laser surgery. A lumen is defined by an interior of the transfer tube, and a laser fiber extends through the lumen for delivering a therapeutic laser signal to a distal end of the laser fiber. An articulating tip at the distal end of the transfer tube is responsive to articulating forces from a retractable tether for directing the treatment probe in a direction of the articulation, and a linkage to the tether from a control module effects controlled retraction of the tether for articulating the tip towards a surgical target, such that the articulating tip imposing a bend radius based on a signal loss through the laser fiber.

Abstract: A photoacoustic imaging approach identifies, concurrently with ablation therapy, an extent of the ablation by measuring and rendering a necrotic extent of treated tissue in a treatment region. Laser pulsed light directed at the treatment region induces an acoustic (ultrasound) signal for differentiating ablated tissue from its non-ablative counterpart based on a photoacoustic spectrum variation. The acoustic signal indicates a range of necrotic extent based on a quantified ablated tissue contrast and a total contrast of both necrotic and non-necrotic tissue, defined as a fraction for computing a degree of necrosis. Generation of an image indicating the degree of necrosis allows continuous or near continuous feedback for ablation therapy guidance to ensure complete and effective ablation of the proper tissue in the treatment region.

Abstract: An atomizing spray dryer employs one or more stages defined by ultrasonic transducers in close proximity to a liquid feed opening forming a path of an atomization flow for producing uniform droplets from a close tolerance with the transducer. The atomization flow exits a gap between the transducer and an outer edge of the opening, such that the passed liquid is responsive to an oscillation of the transducer for forming the droplets. A conical or other suitably shaped transducer engages a substantially round liquid feed opening. Subsequent stages may include a circular, ring, or other suitable shape aligned to receive the atomization flow from a circumference of the conical base, or may also take any suitable shape, preferably to receive droplets directed by the first stage.

Abstract: A PQ signature scheme MMSAT that is capable of aggregating and compressing unrelated messages signed individually by different parties. The scheme extends the notion of multi-signatures, which are signatures that support aggregation of signatures on a single message signed by multiple parties.

Abstract: A ligament repair device and method is particularly suited to the demands of UCL repair using a scaffold device for surgical implantation across a torn ligament section. The implantable device includes an encapsulation of a therapeutic element for increasing cell proliferation and growth eluted through a controlled release storage element adapted to release the therapeutic agent over time as the cell growth progresses and the scaffold structure degrades or is absorbed in favor of the new cell growth for ligament repair. Reduced recovery time is afforded by the need for only an relatively small incision for implantation. The introduction of a physiologically relevant drug delivery scaffold encourages more rapid cell growth over passive, physical repairs to the connective tissue.

Abstract: A method of assessing optical properties of surgical tissue by observing the tissue thermal response to laser irradiation includes exposing the tissue in a surgical region to a short laser pulse for triggering a localized temperature increase, and observing the triggered temperature increase by a thermal sensor. Optical properties of the tissue are then estimated, for determining laser surgery parameters for an eminent procedure, based on the observed temperature increase. In an example configuration, the thermal sensor is a thermal infrared camera, and estimation includes using an Ensemble Kalman Filter (EnKF) for comparing the temperature sensor data with the output of a computational laser-tissue interaction model.

Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

Abstract: A neuromuscular test device for assessing a level of neuromuscular blocking agents (NMBAs) in an anesthetized patient includes a stimulation circuit for initiating a muscular stimulus in a muscle structure, and a testing circuit for measuring an activity level responsive to the muscular stimulus. A flexible, closed vessel is responsive to a musculature response for inducing a pressure, and a pressure sensor in communication with the closed vessel generates a pressure signal indicative of the musculature response to the muscular stimulus.

Abstract: A field of vision assessment is performed by reported positional feedback of visual markers at an outer circumference of a subject's field of vision. An array of visual markers arranged in a grid is rendered near a peripheral vision limit of the subject. The visual markers are disposed at known locations relative to an origin of the field of vision of the subject. Based on reported visual markers, a mapping of the visual markers to the location denotes a point on a periphery of limit of the visual field. The mapped points define vertices of a polyhedron having edges denoted by the vertices and the origin. The volume of the resulting polyhedron correlates to the field of vision of the subject, since as the periphery of the field of vision increases, the computed volume also increases.
