  • Patent number: 12512662
    Abstract: 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.

  • Publication number: 20250199049
    Abstract: 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.

  • Publication number: 20210250279
    Abstract: A computer implemented method comprises receiving an ethernet frame on an access port of a source switch in a switch fabric, the ethernet frame comprising a source media access control (SMAC) address and a destination media access control (DMAC) address, in response to a determination that the destination media access control address is not programmed into a media access control table of the source switch sending a destination lookup failure (DLF) message to a control plane associated with the switch, the destination lookup failure (DLF) message indicating that the destination media access control address received with the frame is not programmed into a media access control table of the source switch, and in response to a determination that the destination media access control address is programmed into a media access control table of at least one switch of the plurality of additional switches in the switch fabric, initiating a sequenced path setup on the source switch.

  • Patent number: 10911797
    Abstract: 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.

  • Patent number: 5832672
    Abstract: 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.
