Patent number: 10628720Abstract: An Internet of Things (IoT) based system for remotely monitoring and controlling various physical parameters for chemical/biological material under transportation in a container is disclosed herein. Due to various circumstances, wither hazardous or infectious, taking proper measures becomes a necessary condition while transporting chemical or biological materials. The sensors attached to the container measure the associated physical parameters and send the data to a remote control system. The dynamic barcode responds to the change in any of the parameters and changes its patterns accordingly. The remote server, based on the received data, instructs a controlling system to control the parameters, thus maintaining the health of the material.Type: GrantFiled: April 4, 2017Date of Patent: April 21, 2020Assignee: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCHInventors: Muthukumarasamy Karthikeyan, Renu Vyas

Patent number: 10467068Abstract: An automated method for remote computing of molecular docking and dynamics from one or more jobs in a network of plurality of users. The invention employs a system to execute the method comprising at least one user device, a remote computing server and a remote database. The job defining action tags are received and scanned by the remote server. A semantic analysis is performed on the jobs to distinguish between customized and non-customized tasks. A data analysis of the jobs is packaged in a compressed format. The user is continually updated of the job status. A public link is generated and sent to the user to download the results. The link is disabled after the downloading of the results to ensure the security of the data. The method avoids any duplication of jobs and can be performed even when the user is offline.Type: GrantFiled: October 28, 2016Date of Patent: November 5, 2019Assignee: Council of Scientific and Industrial ResearchInventors: Muthukumarasamy Karthikeyan, Renu Vyas

Publication number: 20180355514Abstract: Method for encoding and decoding large scale molecular virtual libraries into a barcode Ligand-based drug discovery is often characterized with extraction of scaffolds, linkers and 5 building blocks from large small molecule datasets. Variable sites on scaffolds with attachment sites on building blocks participate in a combinatorial virtual reaction to generate a set of new virtual molecules. This process is time consuming and demands more storage space and is tedious to exchange data digitally. There is practically no quick way to sample molecules without enumerating the virtual library. Therefore, the present invention discloses a method of 10 encoding a virtual library of large scale molecular data into a single barcode. The present invention further discloses a method of decoding the barcode containing large scale data molecules.Type: ApplicationFiled: May 11, 2016Publication date: December 13, 2018Applicant: Council of Scientific & Industrial ResearchInventors: Muthukumarasamy Karthikeyan, Deepak Karbhari Pandit

Patent number: 9151781Abstract: A set of first substrate and second substrate are manufactured with a built-in N-fold rotational symmetry around the center axis of each substrate, wherein N is an integer greater than 1. A set of N different interposers is provided such that an i-th interposer provides electrical connection between the first substrate and the second substrate with a rotational angle of (i?1)/N×2?. The first and second substrates are tested with each of the N different interposers therebetween. Once the rotational angle that provides the highest stacked chip yield is determined, the first and the second substrates can be bonded with an azimuthal rotation that provides the highest stacked chip yield.Type: GrantFiled: February 16, 2012Date of Patent: October 6, 2015Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Oleg Gluschenkov, Muthukumarasamy Karthikeyan, Yunsheng Song, Tso-Hui Ting, Richard P.

Patent number: 8546155Abstract: Method form via chain and serpentine/comb test structures in kerf areas of a wafer. The via chain test structures comprise a first via chain and a second via chain in a first kerf area. The via chain test structures are formed such that geometrically shaped portions of the first via chain and geometrically shaped portions of the second via chain alternate along the length of the first kerf area. The methods perform relatively low (first) magnification testing to identify a defective geometrically shaped portion that contains a defective via structure. The methods then perform relatively high (second) magnification testing only within the defective geometrically shaped portion. The first magnification testing is performed at a lower magnification relative to the second magnification testing.Type: GrantFiled: October 3, 2011Date of Patent: October 1, 2013Assignees: International Business Machines Corporation, STMicroelectronics, Inc.Inventors: Christopher B.

Patent number: 7856332Abstract: A system and a method for effectively determining the measurement sensitivity, repeatability, and probe commonality to assist a test engineer determine if the tester meets the specified resolution at every test. A statistical measurement of inherent tester specifications are provided with the added accumulation of the probe contact resistance during the probing process. It further provides a feedback to the test probe card noise level while testing is in progress. Moreover, the system and the method determine the test probing integrity in-situ when testing integrated circuit chips or wafers, dynamically detecting probing errors, and modifying data associated with defective test probes.Type: GrantFiled: December 4, 2007Date of Patent: December 21, 2010Assignee: International Business Machines CorporationInventors: Muthukumarasamy Karthikeyan, Louis V.

Patent number: 7613047Abstract: The embodiments of the invention provide an apparatus, method, etc. for an efficient circuit and method to measure resistance. A sense line driver for an integrated circuit memory is provided, including a sense node that receives an experiment signal from an experiment structure. An output device is connected to the sense node, wherein the output device amplifies the experiment signal. Further, a voltage divider is connected to the sense node, wherein the voltage divider includes a first device and a second device. A sensing range is controlled by an operating width/resistance range and/or an adjust signal of the second device. The adjust signal changes a gate to source voltage of the second device and holds a constant voltage over multiple sensing instances. The sensing range is different for each of the sensing instances due to a change in the operating width of the second device.Type: GrantFiled: October 5, 2006Date of Patent: November 3, 2009Assignee: International Business Machines CorporationInventors: Jonathan R.
