  • Publication number: 20190385476
    Abstract: In an illustrative embodiment, a wearable system for encoding and a method for comparing a tacit motion is provided including at least one base pod, each base pod having a processor and at least one first sensor in communication with the processor, the at least first sensor configured to sense a first motion of a wearer; one or more distributed modules, each distributed module including at least one second sensor for sensing a second motion of the wearer, each second sensor configured to be in communication with the processor of the base pod and to be positioned at a distinct location relative to a body and/or joint; and where each sensor is positioned at a different distinct location relative to a body and/or joint, where coordinated data from each sensor is configured to be used for detecting a tacit motion.

  • Patent number: 9502995
    Abstract: A micro-hydraulic device includes an enclosure. The enclosure includes a substrate having a first surface and a second surface distal to the first surface. The enclosure further includes a chamber defined between the first surface and the second surface. The chamber is defined by a wall substantially from the first surface to the second surface. The enclosure includes a first flexible membrane sealingly connected to the first surface and disposed over the chamber; and a second flexible membrane sealingly connected to the second surface disposed over the chamber distal to the first flexible membrane. The device further includes an internal fluid retained within the enclosure and a rigid electrode fixed within the chamber having an aperture therein. A flexible electrode is disposed on the second flexible membrane opposite the rigid electrode.

  • Patent number: 9400197
    Abstract: A fluid flow sensor that utilizes hot-wire anemometry and is a small, light weight, cost effective, easily manufactureable, and low power consuming device. The fluid flow sensor operates by exposing a hot wire loop to a fluid stream such that the amount of heat lost to fluid convection is a function of one or more fluid-related parameters (e.g., fluid speed, fluid type, fluid density, etc.). The heat loss affects the resistance in the wire loop, which can then be used to estimate the fluid speed or other fluid-related parameter. According to an exemplary embodiment, the fluid flow sensor includes one or more wire loops that are made from pre-formed wires and are wire bonded, micro-welded or otherwise non-monolithically attached to a substrate that may or may not include embedded sensor circuitry.

  • Publication number: 20140283604
    Abstract: A three-dimensional microelectromechanical systems (MEMS) structure includes a substrate and having a height extending outwardly from the substrate and a largest lateral dimension orthogonal to the height. The largest lateral dimension is smaller than the height. A transducing element is operatively connected to the hair-like core and embedded within, formed on an outer surface of, or disposed at a root of the hair-like core. The transducing element is to receive an electrical core signal or a non-electrical core signal conveyed by the hair-like core. The transducing element is to convert the non-electrical core signal to an electrical output signal, convert the electrical core signal to an electrical output signal in a different format, convert the non-electrical core signal to a different non-electrical output signal, or convert the electrical core signal to a non-electrical output signal.

  • Publication number: 20120045805
    Abstract: The various embodiments herein provide a system and a method of synthesis of thermoplastic biopolymer such as poly-?-hydroxy butyric acid wherein the activated sludge and synthetic waste water are acclimatized in a sequential batch reactor. The diazotrophs are reacted with CO2 in a secondary carbon source reactor. The acclimated activated sludge and the prepared diazotrophs are enriched for production of poly-?-hydroxy butyric acid in a polymer production reactor. The produced polymer is purified and collected. Herein, CO2 is used as a secondary carbon source and is produced from a CO2 generator. The diazotrophs used is azotobacter spp. Chorochome. The system comprises of a sequential batch reactor, a secondary carbon source reactor and a polymer production reactor.
