  • Publication number: 20230117566
    Abstract: Probes that define retroreflectors, probe systems that include the probes, and methods of utilizing the probes. The probes include the retroreflector, which is defined by a retroreflector body. The retroreflector body includes a first side, an opposed second side, a tapered region that extends from the first side, and a light-receiving region that is defined on the second side. The probes also include a probe tip, which is configured to provide a test signal to a device under test (DUT) and/or to receive a resultant signal from the DUT. The retroreflector is configured to receive light, via the light-receiving region, at a light angle of incidence. The retroreflector also is configured to emit at least an emitted fraction of the light, from the retroreflector body and via the light-receiving region, at a light angle of emission that is at least substantially equal to the light angle of incidence.

  • Patent number: 11558375
    Abstract: A virtual keyboard rendered on a separate computing device is independent of the user's computer. A virtual keyboard displayed on the user's computer screen is blank without any alphanumeric characters. Another virtual keyboard displayed on the user's independent computing device has a randomly generated layout of alphanumeric characters on a keypad. The user enters a password by pressing the blank keys of the blank keyboard on his computer screen with reference to the other virtual keyboard. The position sequence of these entered keys is sent to an application on a remote server computer. The remote server computer shares a virtual keyboard having the randomly generated layout of characters with the independent computing device via an online or off-line technique. When online, an encoded image of the encrypted layout is sent to the client computer and displayed for scanning by the device.

  • Patent number: 11516249
    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.

  • Publication number: 20220251173
    Abstract: Antibodies (especially humanized antibodies) against the hepatitis B surface antigen (HBsAg), a nucleic acid molecule encoding same, a method for preparing same, and a pharmaceutical composition containing same. The anti-HBsAg antibodies have a higher binding affinity to HBsAg at a neutral pH than at an acidic pH, thereby significantly enhancing virus clearance efficiency and prolonging virus inhibition time. The antibodies and pharmaceutical composition may be used to prevent and/or treat HBV infections or diseases related to HBV infection (such as hepatitis B) for use in neutralizing the virulence of HBV in the body of a subject (such as a human) to reduce a serum level of HBV DNA and/or HBsAg in the body of the subject, or to activate a humoral immune response of a subject (such as a person infected with chronic HBV or a patient who has chronic hepatitis B) against HBV.

  • Patent number: 11329936
    Abstract: The system executes online on corporate premises or in a cloud service, or offline. An e-mail message is received at a server within a corporate network or cloud service. A header of the e-mail message is parsed to determine locations of server computers through which the e-mail message has traveled. Geographic locations are placed into a routing map. A banner is inserted into the e-mail message that includes the routing map or a link to the routing map. The routing map is stored by the e-mail gateway server at a storage location identified by the link. The modified e-mail message is delivered or downloaded from the e-mail server to a user computer in real time. The sender Web site is parsed to identify sender domain information to be inserted into the banner. If offline, a product fetches and modifies the e-mail message using an API of the e-mail server.

  • Patent number: 11323476
    Abstract: A system is implemented in browser plug-in software or in endpoint agent software on a user computer. The user accesses a Web site and fills in a login request form and submits it to the Web site. The system triggers a “forgot password” feature and detects a phishing Web site by determining that it does not send a reset link to a valid user e-mail address, or, the system detects a phishing Web site by determining that it does send a reset link to an invalid e-mail address. Or, the system detects a phishing Web site by determining that it sends a reset link to a user e-mail address from a domain different from the domain of a login request form. Or, the system fills in an incorrect account name or password in a login request form and detects a phishing Web site by determining that the Web site does not indicate that the incorrect user name or incorrect password are incorrect.

  • Patent number: 11300717
    Abstract: The present invention discloses an optical film and a cover plate for an electronic device. The optical film comprises: a support; a micro/nano-structure layer which is formed by providing a groove on a surface of the support, which groove forms a micro/nano-structure and is provided with a filler; wherein the micro/nanostructure layer has a visual gradient in at least one direction. The present invention provides an optical film, which realizes a visual change or a gradient effect, by adjusting the area ratio of the micro/nano-structure, the depth of the groove, the period of the micro/nano-structure or the density of the micro/nano-structure, and produces a decorative or practical effect. It plays an aesthetic role when used in the casing of an electronic device, and it can shade light but not block the sight line when used in buildings or automotive glass. Furthermore, no black spots will appear with this structure, and it is visually more artistic.

  • Patent number: 11206382
    Abstract: Disclosed are a white balance synchronization method and apparatus, and a terminal device. The method is applied to a terminal comprising at least two cameras, and comprised that: when it is determined that the terminal is about to switch a camera, obtaining a first gain value corresponding to a currently used first camera; and after a second camera is started, using the first gain value as an initial value, and performing white balance adjustment is performed on an image collected by the second camera. Therefore, after the camera is switched, the second camera performs convergence by using gain value of the first camera prior to the switching as an initial value so as to perform the white balance adjustment, thereby avoid the problem of image flickering, improving the white balance adjustment speed and improving the user experience.
