  • Publication number: 20180198869
    Abstract: Embodiments of the present disclosure provides a system for connecting users over a network without requiring the users to share their personal contact details. The system comprises a server, a first user device, and a second user device, wherein the first user device is configured to upload a first image to the server and the second user device is configured to upload a second image to the server. Thereafter, the server compares the first image and the second image to identify if both the images are same images. If the server identifies that both the images are same images, then the server enables the first user device and the second user device to communicate with each other over a platform hosted by the server.

  • Patent number: 9570727
    Abstract: A battery separator is a microporous membrane. The membrane has a major volume of a thermoplastic polymer and a minor volume of an inert particulate filler. The filler is dispersed throughout the polymer. The membrane exhibits a maximum Z-direction compression of 95% of the original membrane thickness. Alternatively, the battery separator is a microporous membrane having a TMA compression curve with a first substantially horizontal slope between ambient temperature and 125° C., a second substantially horizontal slope at greater than 225° C. The curve of the first slope has a lower % compression than the curve of the second slope. The curve of the second slope is not less than 5% compression. The TMA compression curve is graphed so that the Y-axis represents % compression from original thickness and the X-axis represents temperature.

  • Patent number: 8463895
    Abstract: To predict edges in a non-cumulative graph, based on a sequence of non-cumulative previous occurrences of the graph, the sequence of non-cumulative previous occurrences of the graph is obtained, and topological properties of each of the previous occurrences of the graph are extracted. Topological similarities between each of the previous occurrences of the graph are computed based on the topological properties. The edges of the graph are predicted by computing a score for each possible edge of the graph, based upon the topological similarities.

  • Publication number: 20130017431
    Abstract: This invention relates to separators for batteries and other electrochemical cells, especially lithium-ion batteries, having a shutdown mechanism. The separator comprises a nonwoven nanoweb comprising a coating composed of a plurality of thermoplastic particles having particle size larger than the mean flow pore size of the nanoweb. The coating flows at a desired temperature, and restricts the ion flow path, resulting in a substantial decrease in ionic conductivity of the separator at the desired shutdown temperature, while leaving the separator intact.
