  • Patent number: 12218808
    Abstract: The subject matter described herein provides systems and techniques for a network planning and optimization tool that may allow for network capacity planning using key network failures for an arbitrary pair of network topology and demands. Performing network capacity planning with key network failures, instead of using other techniques, may avoid over-building the topology of a network. In particular, key network failures may be generated from the probabilistic failures, and the impact of these failures on a network may be computed. Expected flow availability SLO or a function thereof may be computed, using this information, and used by the tool to design a robust network. With an embedded flow availability calculation and updated risk framework, the capacitated cross-layer network topologies output by the tool may meet network demands/flows with their respective SLO type at the lowest cost.

  • Patent number: 12152712
    Abstract: A three-gear hose clamp apparatus designed to securely fasten around hoses. The apparatus includes a clamping band having openings disposed at distal end and forms a loop around hose, when its distal end and proximal end overlap. The constriction and expansion of clamping band is facilitated by a clamp assembly, which employs a drive helical gear with a head section and threaded shaft. The drive helical gear interfaces with a driven spur gear set at a perpendicular axis, which is in direct contact with an elongated driven helical gear that rotates co-axially, its threads mating with the openings of the clamping band. The mechanism is housed in two distinct housings: one that covers the driven helical gear and another envelops both the drive helical gear and driven spur gear.

  • Publication number: 20240010314
    Abstract: A balanced piston pump (300) for use in subsea vehicles, for example in a variably buoyancy engine, includes an inlet (321), an outlet (325) and at least one fluid path between the inlet and the outlet. A piston arrangement in the fluid path includes a stepped piston (330) having a large end (333) and a small end (331). The step (336) of the piston cooperates with the body (310) of the pump to form a piston chamber (320). The ends (332, 334) of the piston are each exposed to ambient pressure. The force required to drive the pump is dependent on the difference in cross sectional areas of the ends of the pistons.

  • Patent number: 11799569
    Abstract: Aspects provide for dynamic pathloss mitigation via a cross layer tool chain by simulating a three-dimensional model of a physical environment including an access point, an endpoint running an application, and a passive object; emulating network traffic for the application transmitted between the access point and the endpoint; simulating, in the model, pathways for signals to carry the traffic in a plurality of regions for the physical environment; emulating signal degradation along the pathways in the plurality of regions based on respective locations for the access point, the endpoint, and the passive object in the physical environment; and in response to the signal degradation satisfying a pathloss threshold, outputting a command to the application to affect operations of the endpoint. Additionally, the cross layer tool chain outputs a Graphical User Interface showing a signal degradation map based on the simulated network traffic overlaid on the model.
