Abstract: A superhydrophobic surface is formed by growing a plurality of etchable, sacrificial structures, and depositing a discontinuous hydrophobic material onto the sacrificial structures. The discontinuity facilitates etching of the sacrificial structures to remove the grown structures while leaving the deposited material intact to result in surface features for achieving superior hydrophobic properties.

Abstract: Variable stiffness devices and methods of their use are provided. In some embodiments, a variable stiffness device comprises an inner member defining a compartment for receiving an actuating fluid; an outer member disposed around the inner member; and a granular medium disposed between the inner member and the outer member; wherein the inner member is being moveable in a radial direction from a relaxed state to an expanded state by introducing the actuating fluid into the compartment of the inner member to compress the granular medium against the outer member to increase the stiffness of the device.

Abstract: An impact absorbing footwear device employs opposed planar sole portions engaged by a selective resistance coupling that biases the opposed planar sole portions in a non-linear manner in response to forces exerted by the wearer against the sole portion in frictional contact with a floor surface. The planar sole portions are disposed in a footwear appliance that takes the form of an athletic shoe sole. The selective resistance coupling includes a plurality of resilient deformation members that engage the planar sole portions in an opposed circumferentially aligned manner, selectively deform in response to pressure exerted by the wearer for preventing ACL and other impact related injuries, and recover to an undeformed rest position without breakaway to allow the wearer uninterrupted usage while dampening forces that surpass an injury threshold from the resilient deformation that allows the planar sole portions to temporarily misalign.

Abstract: Embodiments of the innovation relate to a mixed reality device having a mixed reality display and a controller disposed in electrical communication with the mixed reality display. The controller configured to receive topology data associated with a network and three-dimensional (3D) embedded network data associated with the network. The controller is configured to construct a hierarchical data structure from the topology data and the 3D embedded network data. The controller is also configured to display a level of the hierarchical data structure as a virtual object in a 3D space on the mixed reality display, the level of the hierarchical data structure identifying a subset of nodes and a subset of edges of the hierarchical data structure.

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 rechargeable lithium-ion (Li-ion) battery employs a low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or spraydrying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material. The metallic binder conveys charge for mitigating or eliminating a need for a planar current collector underlying the sprayed layer. The resulting layers are suitable for battery operation, and are manufactured in an absence of any solvent drying or disposal.

Abstract: A force absorbing device for a footwear appliance includes a shoe sole having a planar sole surface, such that the shoe sole is adapted to be disposed against a ground surface such as turf, grass or dirt. A ground interface member having a general appearance of a footwear cleat extends from the planar sole surface. Within the sole, the ground interface member couples to a force mitigation assembly for absorbing forces against the cleat. The force mitigation assembly includes an elastic field of a resilient, compressible material, and an inclined surface is disposed against the elastic field and oriented to compress the elastic field. A linkage or connecting surface transmits a displacement force for disposing the inclined surface across the elastic field, where the inclined surface compresses the elastic field as it moves across. In response, the elastic field exerts a counterforce against the ground interface member.
