  • Patent number: 11191962
    Abstract: An improved stimulus coil for use in wireless stimulation of biological tissue (e.g., nerves, muscle tissue, etc.) and, in one exemplary implementation, to glaucoma therapy based on the wireless administration of energy to the eye of a mammalian subject (e.g., human, rodent, etc.) to reduce an elevated intraocular pressure (IOP) involving the use of an improved stimulus coil. The improved stimulus coil may be implanted in the eye of a mammalian subject or positioned on the exterior of the eye, such as (by way of example) by being disposed within a contact lens worn by a mammalian subject.

  • Patent number: 11075875
    Abstract: The present disclosure provides a detailed description of techniques used in systems, methods, and in computer program products for bi-directional social media broker services that connect multiple social media sites using a common management framework. The claimed embodiments address the problem of efficiently scaling and managing bidirectional interaction with multiple social media publishing channels. More specifically, the claimed embodiments are directed to approaches for a computing platform having multiple message broker modules that enable bi-directional communication of messages between a common resource manager and a plurality of social media sites. The message broker modules can receive messages in a unified message format from the common resource manager, queue the messages for asynchronous processing, translate the messages from the unified message format to a site-specific format, and deliver the translated messages to multiple social media sites.

  • Patent number: 11038916
    Abstract: An attachment to an e-mail message received at an e-mail gateway is scanned by a scan server and then is converted into an HTML file. The HTML file includes preview data of the attachment (minus any macro scripts), the entire original data of the attachment, scan functionality enabling a user to send the attachment back to a scan server for a second scan, or extract functionality enabling a user to extract the original attachment data for saving or opening in an application. The recipient is able to open or save the attachment directly if he or she believes it comes from a trusted sender. If the attachment seems suspicious, the recipient previews the attachment first before performing a scan, opening the attachment or deleting it. The recipient performs a scan of the attachment by clicking a “scan” button to send the attachment to a backend server for a second scan where an updated virus pattern file may be available to detect any zero-day malware.

  • Patent number: 10999322
    Abstract: The presently-disclosed solution provides an innovative system and method to protect a computer user from a phishing attack. Computer vision is effectively applied to match identifiable key information in suspect content against a database of identifiable key information of legitimate content. In one embodiment, the presently-disclosed solution converts suspect content to a digital image format and searches a database of logos and/or banners to identify a matching logo/banner image. Once the matching logo/banner image is found, the legitimate domain(s) associated with the matching logo/banner image is (are) determined. In addition, the presently-disclosed solution extracts all the URLs (universal resource links) directly from the textual data of the suspect content and further extracts the suspect domain(s) from those URLs. The suspect domain(s) is (are) then compared against the legitimate domain(s) to detect whether the suspect content is phishing content or not.

  • Patent number: 10951833
    Abstract: The present disclosure provides a method and a device for switching between cameras and a terminal. When it is determined that a current zoom factor satisfies a first switching condition, a distance between a current object to be photographed and the camera and/or current illumination is obtained. It is determined whether the distance between the current object to be photographed and the camera and/or the current illumination satisfies a second switching condition. When the distance between the current object to be photographed and the camera and/or the current illumination satisfies the second switching condition, a switch is performed between the cameras.
