Patent number: 12357204Abstract: An oximetry device includes an inductive detector. When the oximetry device is sealed in a sheath and a latch of the sheath is in a latched position, the inductive detector inductively detects that latch. The oximeter device uses first information received from the detector for the latch being in the latched position to allow the device to take oximetry measurements. The oximeter device uses second information received from the detector for the latch not being in the latched position to allow the device to display a message on a display of the device that the sheath is not sealed. The displayed message indicates to a user that the sheath lid needs to be closed. The closed lid prevents contaminants in the sheath from reaching patient tissue during use of the device and sheath.Type: GrantFiled: January 11, 2021Date of Patent: July 15, 2025Assignee: ViOptix, Inc.Inventors: Stephen Matthew Kmak, Robert James Mosley, David Keith Hohl, Willem-Jan Ouburg, Timothy Lee Sauder, Alan Baldwin

Patent number: 12284159Abstract: A router node comprises a link discovery module, a security module, a secure access module and storage. The link discovery module discovers a link to an adjacent router node and receives its first loopback address. The link discovery module creates a first tunnel between the security module in the router node and the first loopback address. The security module receives a second loopback address for the second router node, and creates a second tunnel. The security module repeats the discovering, receiving and creating steps for each router node adjacent to the first router node. The storage separately stores a link discovery routing table which comprises information relating to the links between the router node and each adjacent router note; a security routing table which stores the unique first loopback address; and a secure access routing table which stores the unique second loopback address.Type: GrantFiled: May 18, 2021Date of Patent: April 22, 2025Assignee: BAE SYSTEMS PLCInventors: Stephen Matthew Allan Jenner, David James Sullivan, Benjamin Mark Lee
