  • Publication number: 20240106862
    Abstract: Systems, methods, apparatuses, and computer program products for providing a virtual cloud workload protection platform. One method may include determining, by a device, whether a data stream is approved or unapproved; and transmitting, by the device, a fetch request to a renderer requesting a network resource requested by a protected client. Another method may include receiving, by a rendering device, a fetch request from a device requesting at least one network resource requested by a protected client; requesting, by the rendering device, the requested at least one requested resource; and rendering, by the rendering device, the at least one requested resource.

  • Publication number: 20220370202
    Abstract: A method for 3D printing a prosthetic socket from a digital model, including printing a solid wall perimeter of the prosthetic socket with a width achieved in a single pass of a printing nozzle, and forming a plurality of stiffener elements proximate a bottom end of the prosthetic socket, as a function of the printing the solid wall perimeter, is provided. Also provided is a 3D printed prosthetic socket including an upper portion, a lower portion configured to be attached to a prosthetic pylon, and a plurality of stiffener elements radially extending from the lower portion, wherein the upper portion, the lower portion, and the plurality of stiffener elements are printed as a solid wall construction comprised of a printing material deposited using only a single pass of a printing nozzle.

  • Patent number: 5388541
    Abstract: A tanker ship has upper and lower tanks for carrying cargo. The upper and lower tanks are separated from each other by an intermediate deck. The lower tank is filled with cargo to the intermediate deck such that the cargo is slightly pressurized and there is no ullage space. As the tanker sails, the cargo in the lower tank is likely to change pressure due to temperature changes. These pressure changes are detected by a pipe extending from the lower tank through the intermediate deck up to an ullage space in the corresponding upper tank. A siphon is used to transfer cargo between the upper and lower tanks to equalize the pressures. In the event that the lower tank is breached, sensors are used to detect the resulting drop in pressure from the lower tank cargo. The sensor system provides a warning to the crew, closes the siphon to prevent cargo transfer from the upper tank to the lower tank and opens an auxiliary pipe located in the upper portion of the lower tank.
