  • Patent number: 12643270
    Abstract: A passive horn integrally formed by using liquid silicone rubber, includes a first outer casing, a second outer casing, an inner casing and an iron piece. The first outer casing includes a sealing ring, a folding ring and a vibrating membrane, and the sealing ring, the folding ring and the vibrating membrane are integrally injection molded into the first outer casing. A groove is disposed in the second outer casing, and the first outer casing is disposed in the groove. The back surface of the vibrating membrane is provided with a casing groove, which is sequentially embedded with the inner casing and the iron piece. A preparation method of a passive horn integrally formed by using liquid silicone rubber, under the condition of integrated injection molding, may improve the yield rate, ensure product quality, save assembly time and labor cost, and improve production efficiency.

  • Patent number: 10671568
    Abstract: Systems and techniques of de-duplicating file and/or blobs within a file system are presented. In one embodiment, an email system is disclosed wherein the email system receives email messages comprising a set of associated attachments. The system determines whether the associated attachments have been previously stored in the email system, the state of the stored attachment, and if the state of the attachment is appropriate for sharing copies of the attachment, then providing a reference to the attachment upon a request to share the attachment. In another embodiment, the system may detect whether stored attachments are corrupted and, if so, attempt to repair the attachment, and possibly, prior to sharing references to the attachment.

  • Patent number: 8621614
    Abstract: Computer-readable media and computerized methods for governing treatment of digital communications (e.g., emails and instant messages) upon identifying the communications as potentially phishing emails are provided. A service provider is employed to control behavior of an account that is assigned to an intended recipient of the communications. Controlling the behavior of the account is described in the context of a non-web mail server that renders a UI display, which is not dynamically configurable by the service provider. In one solution, controlling behavior alerts a user to the presence of communications identified as potentially phishing by aggregating these communications in a separate folder. In another solution, controlling behavior facilitates protecting the user by replacing the content of the potentially phishing communications with a warning message.
