  • Patent number: 11913086
    Abstract: A method for relieving residual stresses in a part includes increasing the rotation speed, which includes measuring, at a first given instant, values representative of the rotation speed and the radial enlargement; measuring, at a second given instant after the first instant, values representative of the rotation speed and the radial enlargement; determining a leading coefficient of a first affine function from the preceding values; determining a target radial enlargement value as a function of a value representative of the rotation speed, in the form of a second affine function, the origin of which is the value of a desired final residual enlargement and the leading coefficient of which is the leading coefficient of the first affine function; stopping the increase in rotation speed of the part from the moment that the actual enlargement of the rotating part corresponds to the target relative radial enlargement value that has been determined.

  • Patent number: 11525338
    Abstract: A system for tethering a subsea blowout preventer (BOP) or well head is disclosed. In at least one embodiment, the system comprises an interface associable with the BOP, and more than one anchors disposed about the BOP. Each anchor is configured to carry or support a tensioning system arranged in operable association with a respective tether. Each tether is arranged so as to link a respective anchor with a respective operable means associated with the BOP. Furthermore, each of the respective operable means are configured in operable association with the interface such that tension in the tethers can be adjustable either individually or together as a group of two or more tethers, by way of the interface.

  • Patent number: 10646366
    Abstract: The present invention relates to a shoulder brace for the rehabilitation of patients that suffer from shoulder instability. The shoulder brace uses a novel elevation and compression cabling system to stabilize and approximate the humerus to glenoid fossa. More specifically, the present invention allows an individual that suffers from shoulder instability to easily put on and, while wearing the device, adjust all forces that approximate their shoulder without the assistance of another individual. The design will also allow the individual the ability to have functional movement. This will give someone who has become dependent on others to regain a greater degree of independence.

  • Patent number: 7075887
    Abstract: Retransmission of packets in a TCP network is measured by monitoring packets traversing bearer links between nodes and examining the sequence number within its connection of each packet. For each TCP connection being monitored a next expected sequence number (NESN) value is maintained and compared with the actual sequence number of a packet in that connection. If the sequence number is less than the NESN, a retransmission count is incremented by the size of the retransmitted TCP payload; if it is greater than the NESN, a loss counter is incremented by the size of the lost TCP payload. The resulting counts of the lost and retransmitted TCP payload, of the lost and retransmitted packets, enable accurate measurements to be made even at a point remote from the sending node. Comparison of counts from spaced points in a network can enable the location of a fault to be determined at least approximately.
