Abstract: A prosthetic appliance disposes a plurality of elongated, resilient members in a circular configuration around a pivot point representing a skeletal joint such as an ankle, wrist or shoulder. The resilient members are resilient and adapted to deformable respond to pivoting forces of the fulcrum, and forcibly deform in response to the pivoting of the shaft forcing the fulcrum against the resilient members. The circular orientation of the resilient members pivot the shaft orthogonal to the base from which the resilient members extend, such that the resilient members bias the fulcrum and shaft in the orthogonal position at a rest position. Forces drawing the shaft off-center disposed the fulcrum against one or more of the resilient members and causing resilient deformation and counterforces against the fulcrum back to the centered rest position. In response to pivoting movement, the resilient members apply increasing forces for biasing the pivoting shaft.

Abstract: The techniques herein describe an approach that can quickly geolocate Internet users that are connected through a wireless (e.g., WiFi) network. To do so, one or more embodiments herein send specially-crafted signals to the user's IP address. When these signals are broadcast by the user's wireless router to the user's wireless device, they have a discernible signature. Other geolocation efforts may then be used to scope the Internet user's location (e.g., to the appropriate city or section of a city). A user or automated device may then physically traverse (e.g., drive through) the search area listening on wireless channels for the discernible wireless signature. Once it is located, directional antennas and triangulation may be used to exactly locate the user.

Abstract: A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by storage and controlled release of kinetic energy in an elastic or resilient field. A footwear article such as a shoe or boot includes a split-sole system that redefines a shoe sole as coplanar surfaces having a force mitigating interface for receiving sudden forces and effectively mitigating these forces by storing kinetic energy and releasing it over time. An elastic field in the force mitigation interface is defined by a resilient material adapted to deform in response to the received force. Frictional engagement between the upper and lower sole may also be augmented by surface characteristics such as dimples, voids and lubricants, in addition to interference engagement with an elastic field.

Abstract: An aptamer having an affinity for toxic metals such as lead is introduced by a biocompatible delivery mechanism such as a DNA or RNA strand to which the aptamer is attached. The delivery mechanism delivers the aptamer, either as a direct nucleic acid sequence or expressed in a cell as a probiotic. When delivered as a prophylactic to the gastrointestinal tract (orally) as an aptamer or expressed within a probiotic cell, this would prevent absorption of metals and would thus reduce or eliminate the need for chelation therapy and thereby reduce disease burden. When used therapeutically, it could be ingested, or injected intravenously. Once bound, the toxic metals are expelled through normal gastrointestinal or urinary processes.

Abstract: A volatile liquid storage container has combustion resistance properties from a flexible sock or tube constructed of fire resistant fibers coupled to a neck of the storage container to prevent flame flash-back into the storage container. The storage container defines an enclosed volume having an orifice in the container material leading to a neck for pouring and filling the enclosed volume for exchanging the contents therein. The tube is elongated and surrounds a circumference of the orifice for engaging any ignition source entering through the orifice. The flexible nature of the tube or sock allows it to extend to an opposed interior surface of the enclosed volume, and ensures that the tube or sock is immersed in the fluid for encircling any ignition path to the volatile liquid without interfering with an ability to pour or refill the container.

Abstract: A carbon-negative Engineering Structural Material (ESM) has a compressive strength approaching that of concrete and relies on a carbon-absorbing enzyme for crystalline formations formed cooperatively with a porous structure to achieve load-bearing properties. A tough scaffold forms through capillary suspension, a technique that utilizes capillary forces to concentrate particles in a liquid matrix. Carbonic anhydrase, a zinc-containing enzyme extracted from bovine erythrocytes, is harnessed to grow mineral materials, and the capillary suspension is used to create a construction material, including sand and a polymer. This combination enables the incorporation of precipitated calcium minerals into the structure, resulting in the development of water-resistant and load-bearing construction materials.
