  • Patent number: 12253484
    Abstract: A system for measuring a heat response of a battery cell includes a cell chamber configured to receive the battery cell therein. The cell chamber is configured to trigger a battery cell into a thermal runaway event while in the cell chamber, which causes the battery cell to eject an electrode winding, particles, and gas. The system also includes an ejecta bore muffler configured to receive the electrode winding, the particles, and the gas. The system also includes an ejecta basket configured to be positioned at least partially within the ejecta bore muffler. The ejecta basket is configured to capture the electrode winding while allowing at least a portion of the particles, the gas, or both to pass therethrough. The system also includes a gas collection system configured to receive at least a portion of the gas that passes through the ejecta basket.

  • Patent number: 11038860
    Abstract: In virtualized environments a method of determining authorization to a resource cannot use a hardware specific identifier, such as a MAC address. As a result upgrading a virtual host may cause licenses associated with that host to be invalid, even though the upgraded virtual host should be authorized. Authentication methods and systems are disclosed such that a key may be shared with a second host along with a license file and, provided at least the second host has a key associated with its system identifier and a key associated with a license file, access to a licensed resource may be authorized.

  • Patent number: 10084797
    Abstract: A first login request of a user is received from a first login window. The first login request comprises a login name, a user identifier, and a challenge. The challenge is generated and received from a second login request to a product in a second login window. The user copies and pastes the challenge into the first login window. A central control system determines if the login name and the user identifier are valid. If the login name and user identifier are valid, a response to the challenge is generated based a private key and is displayed in the first login window. The response to the challenge is copied from the first login window and pasted as part of a second step the second login process. The second login process verifies the response to the challenge using a public key to allow the user access to the product.

  • Patent number: 10051067
    Abstract: In order to provide a more realistic system activity score, an activity monitor gathers activity scores from a plurality of processes on one or more communication systems. An activity score defines an activity level of a particular process. For example, how many cache hits per second are occurring in a communication system or how may a HTTP sessions a web server is handling per second. Because the activity scores are gathered from individual processes within the communication system(s), a more realistic understanding of the overall activity of the communication system(s) can be determined. The gathered activity scores are summed to produce a system activity score. The system activity score is then sent to a user. The user can then utilize the system activity score to better manage the communication system(s).
