Patent number: 12512662Abstract: The present technology relates to fault-managed power (FMP), and particularly, to generating FMP in an industrial automation environment using single-pair Ethernet (SPE) cabling for use by DC motors. An FMP system may include a transmitter circuit and receiver circuits coupled together via a transmission link formed using SPE cable. The transmitter circuit can generate a FMP and transmit a pulsed signal having the FMP to the receiver circuits. The transmitter circuitry can also exchange data signals with the receiver circuits over a communication channel using the SPE cable. The receiver circuits can identify an expected power consumption of DC motors coupled to the receiver circuits and provide an indication of the expected power consumption to the transmitter circuit. The transmitter circuit can detect a fault based on a comparison between the transmitted FMP and the power consumption and terminate transmission of the FMP in response to detecting the fault.Type: GrantFiled: December 19, 2023Date of Patent: December 30, 2025Assignee: Rockwell Automation Technologies, Inc.Inventors: Scott Griffiths, David D. Brandt, Michael Cook, Arun Guru, Jon Vanderpas, Robert Schmidt

Publication number: 20250199049Abstract: The present technology relates to fault-managed power, and particularly, to generating fault-managed power in an industrial automation environment using single-pair Ethernet cabling. A fault-managed power system may include transmitter circuitry and receiver circuitry coupled together via a transmission link formed using single-pair Ethernet cable. The transmitter circuitry can generate a fault-managed power based on power from a power source and transmit an unpulsed signal, including the fault-managed power, to the receiver circuitry via the transmission link. The receiver circuitry can identify an expected power consumption of one or more loads coupled to the receiver circuitry and provide an indication of the expected power consumption to the transmitter circuitry. The transmitter circuitry can detect a fault based on a comparison between the transmitted fault-managed power and the power consumption and terminate transmission of the fault-managed power in response to detecting the fault.Type: ApplicationFiled: December 19, 2023Publication date: June 19, 2025Inventors: Scott Griffiths, David D.

Patent number: 10911797Abstract: A method of adjusting video image data to reduce photosensitive epilepsy (“PSE”) triggers, the method including evaluating a sequence of video images to determine if the number of changes in brightness exceeding a predetermined threshold between contiguous images is greater than a predetermined value over a predetermined time or predetermined number of video images; and if the determined number exceeds the predetermined value then applying a correction procedure to the sequence of images. The correction procedure includes: for each image, applying a plurality of candidate brightness changes to the image and subsequently determining which of the applied changes result in the number of changes in brightness between contiguous images exceeding the predetermined threshold being reduced to below the predetermined value; and selecting the determined applied change having the smallest brightness change.Type: GrantFiled: September 9, 2015Date of Patent: February 2, 2021Assignee: Telestream UK LtdInventor: Scott Griffiths

Patent number: 5832672Abstract: A device for anchoring a corner of a beach blanket or towel to the sand of a beach. The device includes a clamp removably attachable to the corner of the beach blanket or the towel for enabling the corner to be anchored to the sand of the beach, and a spike removably receivable in an eyelet defined on the clamp, for anchoring the clamp and thus the corner of the beach blanket or towel to the sand of the beach. The spike includes a locking mechanism for locking and unlocking the spike within the eyelet of the clamp.Type: GrantFiled: March 31, 1997Date of Patent: November 10, 1998Inventors: Scott Griffiths, Richard Davis
