Abstract: A method of providing an interactive personal mobility system, performed by one or more processors, comprises determining an initial pose by visual-inertial odometry performed on images and inertial measurement unit (IMU) data generated by a wearable augmented reality device. Sensor data transmitted from a personal mobility system is received, and sensor fusion is performed on the data received from the personal mobility system to provide an updated pose. Augmented reality effects are displayed on the wearable augmented reality device based on the updated pose.

Abstract: A waste water treatment system utilizing a series of individual modules which, when assembled, form a beginning contaminate collection chamber attached at the starting end of a main fluid treatment tank, in which is housed an array of anodes and cathodes. A center contaminate collection chamber can be attached at the oppose end of the main treatment tank which provides an internal fluid pathway to allow fluid transfer from the first treatment tank into a second treatment tank. Alternatively, the center contaminate collection chamber can be used when multiples of treatment tanks are assembled to work in tandem, or an ending contaminate collection chamber can be attached to an ending treatment module to complete the expandable waste water treatment system. Expandability of the system can therefore accommodate various waste water treatment mechanisms, residence time and manner of treatment.

Abstract: An augmentation amplifier is provided for aspirating gas flow from a surrounding medium. The amplifier connects at an inlet to a pressurized gas source and at an outlet to a gas receiver. Ambient gas from the medium supplements source provided compressed gas. The amplifier includes a Venturi conduit including a throat, an external cavity and a diffusion chamber. The conduit receives and flows pressurized gas from the inlet to the throat. The cavity receives ambient gas from the medium. The chamber expands and accelerates the pressurized gas from the throat to entrain the ambient gas via aspiration. The accelerated and ambient gases combine into an exhaust gas to the outlet.

Abstract: A process for removing oil and other organics, especially naphthalenic acid, is disclosed. The process involves use of electrical fields using electrodes in the device, inducing gas bubbles which force contaminants to the surface of the solutions to be skimmed off and recovered.

Abstract: A pet door is provided herein. The pet door includes a pivotal flap and a frame that defines a through-way. A rotatable knob is mounted to the frame and has a handle portion and a stop wall. The handle portion and stop wall include various profiles and configurations that work in concert to control the flap's direction of pivotal movement. In a first configuration, the flap may swing outwardly or inwardly. A second configuration prevents the flap from swinging inwardly. A third configuration prevents the flap from swinging outwardly. A fourth configuration places the flap is in a locked position to prevent swinging in either direction. The electronic door also includes an electronic latch mechanism which selectively latches and unlatches the flap. The latch mechanism unlatches the flap in response to a wireless signal from an electronic transmitter that may be affixed to a pet.

Abstract: A method of preparing micro-capsules. The active ingredient, preferably provided in the form of an acid salt dissolved in a basic aqueous solution, is emulsified into a polymer solution, preferably PLGA in a relatively volatile solvent such as dichloromethane, to create a water in oil emulsion. This emulsion is further emulsified into an aqueous solution having a pH of a between about 7.4 and 8.0 and most preferably between about 7.8 and 8.0 to create a water in oil in water solution. The polymer solvent is allowed to evaporate, causing the emulsified active ingredient and surrounding polymer matrix to precipitate, thereby forming the micro-capsules. The micro-capsules are separated from the suspension, washed and freeze dried. The method has a very high encapsulation efficiency, even at high loading rates. Additionally, the dissolution rate of the micro-particles produced by the method is very steady over a long period of time.

In alternate embodiments, the consecutively applied layers may contain coating materials, active ingredients or a mixture of coating materials and active ingredients; the layers can be applied in varying order. Also provided is a system for applying the coatings, wherein the syringe pumps are controlled by a computer in accordance with predetermined instructions.

Abstract: Remediation of soil and groundwater using electropotential gradient induced migration of a target ion and immobilization and/or confinement of the target ion by a host receptor matrix (HRM). In addition to immobilizing and/or confining the target ion, the HRM can comprise a buffer or an ionizable species which releases an exchange ion during application of the electropotential gradient. The exchange ion, when less mobile than a (H.sup.+) ion or hydroxyl (OH.sup.-) ion, increases the efficiency of energy usage during decontamination. The exchange ion can also perform other tasks in the vicinity of the electrodes which improve the decontamination process. The host receptor matrix also can comprise a material which is water impermeable and which has a low surface energy, such as a layer of polytetrafluoroethylene film. When such a material is used, the host receptor matrix can comprise a receptacle in which there is a liquid and/or solid composition which immobilizes and/or contains the target ion.

Abstract: Processes and apparatuses for separating ions from an aqueous solution are provided which utilize a first separation by an ion exchange medium in combination with second separation by a D.C. electropotential gradient. The first separation separates the target ion by ion exchange and the second separation effects migration of the ions from the ion exchange medium, through a ion permeable, hydrophobic membrane into a second zone, which may contain a buffer. The hydrophobic membrane substantially resists fouling.

Abstract: Processes and devices are disclosed for converting an aqueous waste solution, such as a radioactive waste stream, into a highly concentrated sludge having substantially little or no water. In turn, the sludge may be converted into a solid polymeric form suitable for storage. The processes utilize a carrier liquid which has a boiling point higher than that of water, and which facilitates the transfer of heat to the water to vaporize the water into steam. A subsequent separation of the dewatered solution yields the highly concentrated sludge.

Abstract: Methods for the encapsulation and solidification of waste material, particularly radioactive ion exchange resin bead media, are provided along with the apparatus to accomplish the methods, and the final encapsulated storage article. The ion exchange resin is solidified within a containment vessel by the addition of a thermosettable polymeric binder without the need for a pre-mixing vessel. The resulting exothermic conditions occasioned by the curing of the polymer are controlled by the sequential delivery of the polymeric binder, preferably through an injection lance.
