Patent number: 11595396Abstract: A smart process control switch can implement a lockdown routine to lockdown its communication ports exclusively for use by devices having known physical addresses, enabling the smart process control switch to prevent new, potentially hostile, devices from communicating with other devices to which the smart process control switch is connected. Further, the smart process control switch can implement an address mapping routine to identify “known pairs” of physical and network addresses for each device communicating via a port of the smart process control switch. Thus, even if a new hostile device is able to spoof a known physical address in an attempt to bypass locked ports, the smart process control switch can detect the hostile device by checking the network address of the hostile device against the expected network address for the “known pair.Type: GrantFiled: May 18, 2021Date of Patent: February 28, 2023Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Alexandre Da Silva Peixoto, Paul Greuniesen, Neil J.

Patent number: 11516521Abstract: A processor system and computer-implemented method may be provided for generating a composite video stream which may combine a background video and a foreground video stream into one stream. For that purpose, a spatially segmented encoding of the background video may be obtained, for example in the form of a tiled stream. The foreground video stream may be received, for example, from a(nother) client device. The foreground video stream may be a real-time stream, e.g., when being used in real-time communication. The image data of the foreground video stream may be inserted into the background video by decoding select segments of the background video, inserting the foreground image data into the decoded background image data of these segments, and by encoding the resulting composite image data to obtain composite segments which, together with the non-processed segments of the background video, form a spatially segmented encoding of a composite video.Type: GrantFiled: July 29, 2019Date of Patent: November 29, 2022Assignees: KONINKLIJKE KPN N.V., NEDERLANDSE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK TNOInventors: Alexandre da Silva Pratas Gabriel, Mattijs Oskar Van Deventer, Hans Maarten Stokking
