  • Publication number: 20240238697
    Abstract: This disclosure relates to an annular centrifugal extractor with Solid Separation Part to Separate Solid Particles Present in Solvent Extraction Fluid. In order to remove solid particles from the solution, a solid separation part/rotating bowl is attached to rotating bowl in such a way that solid particles settle inside the solid separation part. This solid separating centrifugal extractor contains two parts: (I) upper part which acts as a liquid-liquid separator to separate aqueous and organic solution used in solvent extraction operation and (II) bottom part which acts as a solid separator to separate solid particle present in solvent extraction liquids. The bottom rotating rotor is coupled with upper rotating rotor by threading arrangement. Both the rotating rotors are confined within a stationary cylinder. Dispersion with solid particles entering inside the rotating bowl is deflected towards the wall of the rotating cylinder by deflecting baffle by centrifugal sedimentation.

  • Publication number: 20220304575
    Abstract: The invention provides a system and method for a mobile-powered desktop ECG system configured for remote monitoring of a patient. Analog ECG waveforms from probes attached to a patient are shared with a base ECG unit. The received analog ECG waveforms are converted into digital ECG waveforms and shared with a smartphone that powers the base ECG unit. The digital ECG waveforms are processed in the smartphone through an ECG application and sent to a cloud. The ECG application enables the smartphone connect with a medical practitioner in case a medical emergency is detected.

  • Publication number: 20170214678
    Abstract: Embodiments of the invention provide a method and apparatus (“system”) that overcome the above-mentioned problems among others and provide an innovative solution aimed at creating an interactive, dynamic and effective multi-media object with HIP capabilities which may be used in online advertising, security, and user-defined security. The system leverages the existing HIP CAPTCHA real estate to create multi-media objects that guarantee a captivated audience, especially in online advertising. Combining interactive multi-media objects with HIP capabilities helps to meet a very critical need faced by advertisers and websites today—creating an effective impression of any multi-media object on a user (a guaranteed eyeball). Embodiments of the current invention introduce a variety of formats that involve interacting with a multi-media object to provide a more natural user interaction and ease of use while maintaining security.

  • Patent number: 9695408
    Abstract: The present invention relates to novel mutants of Streptokinase, its functional fragments and covalently modified forms. Methods are provided for the preparation of the bacterial plasminogen activator protein, Streptokinase its muteins, species variants and their covalently modified variants that are characterized by improved therapeutic properties, such as increased proteolytic stability, extended plasma half-lives, reduced immuno-reactivity and enhanced fibrin clot specificity. The method involves either incorporating additional cysteine residues, or substituting cysteine residues for naturally occurring amino acids into non-essential regions of the protein such that the catalytic activity of the resultant protein remains largely unaltered. These cysteine variants were further modified by covalently attaching a cysteine reactive polymer such as polyethylene glycol (PEG) or sulfhydryl-reactive moieties from a group that includes fluorophore, spin labels or other small conjugates.

  • Patent number: 9269094
    Abstract: A system and method provide digital online surveys and testing using interactive multi-media content with an option to enable and disable Human Interaction Proof (HIP) capabilities. The system uses random interactivity with multi-media content as HIP validation and subsequently make the user take a test or online survey. The system associates successful completion of tests to rewards. The rewards are awarded by publishers or stakeholders wanting to conduct the survey or test or by third party affiliates that are part of the exchange connecting the content provider and the advertiser wishing to conduct the test, with the option to enable and disable HIP capabilities. The system segments such tests and surveys across demographics. The system captures analytics as part of HIP along with testing and survey results. Such combined analytics have demographics as different dimensions. The system uses haptic technology for HIP and to complete the test or survey.
