Patent number: 10221984Abstract: High-pressure cryogenic fluid conduits that deliver high-pressure cryogenic fluids from a first point to a second point. This high-pressure fluid conduit has a safety feature that is activated when the high-pressure cryogenic fluid conduit fails due to exposure to a predetermined force. The safety feature is activated by the fracture of an annular ring that is positioned at either end of the high-pressure fluid conduit and is calibrated to fracture when exposed to the predetermined force. Fracture of the annular ring closes valves at each end of the high-pressure fluid conduit, thereby stopping the flow of high-pressure fluid from the high-pressure fluid source as well as the escape of high-pressure fluid from the high-pressure fluid container.Type: GrantFiled: May 10, 2016Date of Patent: March 5, 2019Assignee: Zena Associates, LLCInventor: Robert Cardona

A first trace tag identifier is associated with the first transaction at the first trace point. The first transaction is identified at one or more other trace points based on the first trace tag identifier. Based on time stamps at which the first transaction is identified at the trace points, information such as trace information, latency, locality of a consuming device of the first transaction, etc. is obtained from the various trace points.Type: GrantFiled: March 31, 2016Date of Patent: October 30, 2018Assignee: QUALCOMM IncorporatedInventors: Sean Todd Baartmans, Zainab Zaidi
