A transition from night mode to…

State determination and device control

Granted: February 4, 2025
Patent Number: 12218950
Systems and methods for security-based device control are disclosed. For example, a presence-based trigger event is detected and one or more suggestion models are utilized to determine whether a security-based device control suggestion should be sent. Multiple suggestions are arbitrated, and a user device is selected for receiving the suggestion based on multiple inputs. The format of the suggestion is also determined and the suggestion is either automatically output on the selected…

Security protocol handshake offloading

Granted: February 4, 2025
Patent Number: 12218923
Contents of client-initiated handshake messages of a security protocol are obtained at a handshake processing offloader configured for an application. The offloader uses a first security artifact (which is inaccessible from a front-end request processor of the application) and the contents of the handshake messages to generate a second security artifact. The second security artifact is transmitted to the front-end request processor, which uses it to perform cryptographic operations for…

Ethernet traffic over scalable reliable datagram protocol

Granted: February 4, 2025
Patent Number: 12218841
Methods and apparatuses for improving network packet transmission performance in terms of latency with reduced packet retransmission times and fewer packet drops in congested networks are provided. Packet-switched networks can experience long delays while waiting for out-of-order packets or re-transmissions of lost packets. In addition, network faults such as transmission path failures can result in excessive delay while attempting to find a new route over which to transmit packets. To…
