  • Patent number: 11757700
    Abstract: A computing system receives, from a client device, a first request for access to a single page application associated with the computing system. A gateway of the computing system intercepts the first request before it reaches a shell service associated with the single page application. The gateway sends a second request for the single page application to the shell service. Based on the single page application request, the gateway determines that the shell service is experiencing a failure. Responsive to determining that the shell service is experiencing a failure, the gateway retrieves, from a content delivery network, a uniform resource locator (URL) associated with a time-lapse hypertext markup language (HTML) of the single page application. The gateway redirects the client device to the time-lapse HTML of the single page application using the URL.

  • Patent number: 11341585
    Abstract: A hyper-graph sketching framework receives graph data set to generate non-singular reverse cascades in a network to assess influence dynamics therein. A high-quality influence oracle for seed sets uses the resulting sketch data set generated from the non-singular reverse cascades to output estimation of influence.

  • Patent number: 9895244
    Abstract: Segmented scaffolds composed of disconnected scaffold segments are delivered to an implant site on a delivery balloon. The segments are crimped to the balloon and separated from each other by gaps. When the balloon is inflated the gaps between the disconnected scaffold segments stay constant. Pillowed or banded balloons are used to deliver the segments.

  • Patent number: 9642729
    Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the catheter by a multi-step process for increasing scaffold-catheter yield following a crimping sequence. Damage reduction during a crimping sequence includes modifying blades of a crimper, adopting a multi-step crimping sequence, and inflating a supporting balloon to support the scaffold during crimping.

  • Patent number: 9642730
    Abstract: Methods for making scaffolds for delivery via a balloon catheter are described. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold structure has patterns that include an asymmetric or symmetric closed cell, and links connecting such closed cells.
