Patent number: 10980443Abstract: 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.Type: GrantFiled: June 5, 2017Date of Patent: April 20, 2021Inventor: Sai Kumar

Patent number: 10576201Abstract: 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.Type: GrantFiled: August 14, 2015Date of Patent: March 3, 2020Assignee: SFC Fluidics, Inc.Inventors: Forrest W. Payne, Greg Lamps, Champak Das, Sai Kumar, Ashley Shemain

Patent number: 10366315Abstract: 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.Type: GrantFiled: August 15, 2018Date of Patent: July 30, 2019Assignee: FMR LLCInventors: Sai Kumar, Ramanathan Ramamoorthy, Giri Venkataramanan

Magnetohydrodynamic Microfluidic Systems Including Modified Electrodes And Methods Of Using The Same
Publication number: 20180238830Abstract: 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.Type: ApplicationFiled: April 19, 2018Publication date: August 23, 2018Applicant: BOARD OF TRUSTEES OF THE UNIVERSITY OF ARKANSASInventors: Ingrid Fritsch, Christena Nash, Sai Kumar, Timothy Muldoon, Kartik Balachandran, Adair Claycomb, Matthew D.

Publication number: 20130267311Abstract: 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.Type: ApplicationFiled: February 11, 2013Publication date: October 10, 2013Inventor: Sai Kumar
