  • Patent number: 10980443
    Abstract: A device for increasing a user's awareness of his or her breathing includes a clip configured to attach to a user's nose, a hinge connected to the clip, an air deflection plate pivotably connected to the hinge and one or more sensors coupled with the air deflection plate. The air deflection plate is configured to pivot relative to the clip to at least partially deflect air flow into or out of a nostril while the air deflection plate is exterior to the nostril and the clip is attached to the user's nose. The one or more sensors are configured to sense data pertaining to the user's breathing through the nostril. A method for increasing breathing awareness includes, in response to air flow across an air deflection plate pivotably coupled with a clip gripping a user's nose, receiving breathing data with one or more sensors coupled with the air deflection plate.

  • Patent number: 10576201
    Abstract: A valve for use in connection with microfluidic devices includes a safety feature such that flow is controlled even in the case of a loss of power, thus having applications in critical applications such as the precise delivery of drugs overtime. The valve may be used in connection with multiple tubes delivering drugs, and may be used with a pump, such as an electrochemical pump, to provide the force to move the fluids containing drugs for delivery. In certain applications, more than one medicine may be delivered and metered independently using a single pump with multiple reservoirs and valves.

  • Patent number: 10366315
    Abstract: Methods and apparatuses are described for generating a quick response (QR) grid that represents electronic data associated with a digital document. A server captures electronic data associated with a digital document, the electronic data comprising a plurality of key-value pairs. The server determines a total size of the electronic data and partitions the electronic data into two or more portions. The server generates a map of QR codes based upon the two or more portions of electronic data, each QR code in the map comprising a header, a footer, and a payload containing one of the two or more portions of electronic data. The server creates a QR grid using the map of QR codes. The server prints a physical document that corresponds to the digital document, the physical document including the created QR grid.

  • Patent number: 10251434
    Abstract: A device to increase a person's awareness of his or her breathing rhythm is disclosed. The device includes a clip, an air deflection plate, and a hinge connecting the air deflection plate to the clip. The air deflection plate may rotate about the hinge, relative to the clip. The air deflection plate may at least partially occlude a user's nostril when the clip is attached to the user's nose.

  • Publication number: 20180238830
    Abstract: A magnetohydrodynamic microfluidic system and a method of pumping a fluid using a magnetohydrodynamic system are disclosed. The method includes applying at least one of an electric current and an electric voltage to a first modified electrode and a second electrode to generate an ionic current between the first modified electrode and the second electrode and to cause a current carrying species to move to or from the modified electrode, applying a magnetic field perpendicular to an ionic current vector, the magnetic field and the ionic current combining to induce flow of the fluid in a direction perpendicular to the magnetic field and the ionic current vector, and maintaining fluid flow by recharging the modified electrode.

  • Publication number: 20150224499
    Abstract: An automated assay platform for determining the presence and/or amount of analytes of interest in a sample at point of care integrates microfluidic enhanced assay sites, disposable cartridge designs, a sensitive low-volume detection module, together with selected pumping and valving modules, customized control board and user friendly graphical user interface (GUI). Comparing to traditional assay platform like 96-well ELISA, the platform is capable of reducing reagent consumption, increasing assay speed, and enhancing assay performance with a sample-in-answer-out automated process. This platform also features flexibility of adapting different assay schemes for different analytes.

  • Publication number: 20130267311
    Abstract: A game apparatus includes a media conversion engine configured to convert starting media having true component objects into converted media having identity-obscured component objects. A player interface of the game apparatus receives, from players, identity hypothesis information regarding the identity-obscured component objects and a hypothesis tester compares the identity hypothesis information with a true identity input and outputs feedback. Feedback output is presented to players through the player interface. A method for playing a game using the game apparatus is also included.
