Patent number: 11985112Abstract: Techniques are disclosed for transmitting a secure message over a public or untrusted network. The techniques include receiving a message and creating multiple hash values of the message. A sending device signs and encrypts the message and hash values, then encapsulates and transmits to the message and hash values a security server. The security server receives and de-encapsulates the message and hash values, decrypts the message and hash values, and verifies the signature. The security server verifies the hash values and determines whether any changes were made to the message during transmission. If verified, the security server processes the message for transmission to the recipient. The security server creates multiple hash values of the original message, signs and encrypts the message and the hash values, encapsulates the message and hash values and transmits to a recipient device for further verification and presentation to the recipient.Type: GrantFiled: December 18, 2018Date of Patent: May 14, 2024Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Benjamin Kapp, Jibu Abraham, Kevan O.

Patent number: 11971220Abstract: A transducer system comprising a housing, an electromechanical transducer within the housing, a wicking material adjacent to a portion of the electromechanical transducer, and a multi-phase coolant solution within the housing. The multi-phase coolant solution transitions from a first phase to a second phase in response to a temperature of the electromechanical transducer exceeding a threshold temperature. In some example cases, the multi-phase coolant solution has a boiling point of less than about 60° C., which effectively defines the threshold temperature. The multi-phase coolant solution may be chosen such that it remains a liquid during a first phase (cooling via conduction), and then evaporates during a second phase (cooling via conduction and convection) as the electromechanical transducer heats up.Type: GrantFiled: February 9, 2023Date of Patent: April 30, 2024Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Charles P.

Patent number: 11956162Abstract: An asynchronous medium access control layer scheduler increases efficiency for directional mesh networks by removing extra overhead in the time slots. The efficiency is increased by dividing time slots into sub-slots to allow for a receiving node to be offset by at least one sub-slot from the transmitting node. This enables the scheduler to more efficiently schedule operations for the nodes so that nodes can be performing other functions rather than waiting to receive a transmission or waiting after transmitting a transmission. The sub-slots may be sized to approximate the transmission propagation time or time of flight delay.Type: GrantFiled: February 15, 2023Date of Patent: April 9, 2024Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Matthew J.
