    摘要: The disclosed invention provides system and method for multi-path mesh network communications. The network system utilizes multiple communication paths and linearly encoded and disassembled packets through mathematical coding techniques that respectively travel the communication paths. The system includes an encoder, a transmitter, a decoder and a receiver. The encoder receives data from an external source and linearly encodes and simultaneously disassembles the data to generate copackets. None of the individual copackets contain decodable information of the data. The transmitter is coupled to the multiple communication paths and respectively transmits the copackets through different communication paths. The receiver receives the copackets transmitted through the communication paths. The decoder decodes available copackets and reassembles the data from the available copackets if a number of the available copackets are no less than a mathematically calculated number. The reassembled data has the complete information of the data originally transmitted.

    摘要: Losses in the connecting line between the Pressure Wave Generator and the cold head of a GM type pulse tube refrigerator, are reduced while maintaining or improving upon the desirable features of a standard corrugated hose connecting line including vibration isolation, separation distance, and mounting convenience. The basic means are to reduce the internal void volume of the convolutions in a corrugated hose in combination with reducing the number of corrugations, adding fillers to the void volumes, and vibration absorbing coatings.

    摘要: A system and a method for secure operator onboarding and creating an ingest job agent for secure multitenant operations of a distributed computing cluster are provided. Embodiments automate multitenant operations for distributed computing clusters. These operations include automation of operator onboarding, creation of logically segregated distributed data stores within the distributed computing clusters for the on-boarded operator, and creation of ingest agents with security isolation for transfer of large quantities of files into the distributed computing clusters. Embodiments provide multitenant security, in which the same Hadoop cluster serves multiple operators with each operator's data and processes in effective isolation. In this manner, multitenant security keeps each user's data storage and operations on the Hadoop cluster separated from other operators.

    摘要: The disclosed invention provides a bridge voltage inversion circuit for vacuum gauge and a pressure gauge sensor that includes the bridge voltage inversion circuit. The bridge voltage inversion circuit for a pressure gauge includes a reference capacitance, a sensor capacitance, and a transformer including a primary winding and a secondary winding that outputs a bridge voltage. The reference capacitor is connected to a first side of the secondary winding of the transformer, and the sensor capacitor is connected to a second side of the secondary winding of the transformer. The sensor capacitor senses and responds to a pressure, and a capacitance of the sensor capacitor is at a minimum when the pressure is at vacuum. The capacitance of the sensor capacitor at vacuum is less than a capacitance of the reference capacitor.

    摘要: Disclosed herein is a helicopter flight support for use in case of emergencies. The helicopter flight support comprises a motor which causes a threaded shaft to turn which is coupled to an underside of the helicopter. This causes outer supports and inner supports to be deployed until they reach a wing-like configuration. The interior of the wing comprises a plurality of support cables for tensioning the wing. The helicopter flight support further comprises upper and lower support cables mounted to the tips of the wing to provide horizontal stability.
