Patents by Inventor Wen SI

Wen SI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240291638
    Abstract: A method includes obtaining a key status for a first cryptographic key. The first cryptographic key is used to encrypt replicated data of a first replication instance. The method also includes determining, based on the key status, that the first cryptographic key is inaccessible which causes the first replication instance to be unavailable. In response to determining that the first cryptographic key is inaccessible, the method includes scheduling a second replication instance to be unavailable after a threshold amount of time has passed. The second replication instance includes replicated data encrypted by a second cryptographic key that is accessible. After the threshold amount of time has passed and when the first cryptographic key is still inaccessible, the method includes setting the second replication instance as unavailable.

  • Publication number: 20230170581
    Abstract: Implementations of the present disclosure generally relate to separators, high performance electrochemical devices, such as, batteries and capacitors, including the aforementioned separators, systems and methods for fabricating the same. In one implementation, a separator is provided. The separator comprises a polymer substrate, capable of conducting ions, having a first surface and a second surface opposing the first surface. The separator further comprises a first ceramic-containing layer, capable of conducting ions, formed on the first surface. The first ceramic-containing layer has a thickness in a range from about 1,000 nanometers to about 5,000 nanometers. The separator further comprises a second ceramic-containing layer, capable of conducting ions, formed on the second surface. The second ceramic-containing layer is a binder-free ceramic-containing layer and has a thickness in a range from about 1 nanometer to about 1,000 nanometers.
