    摘要: A plasma arc torch and method for improving the life of the consumable parts of the plasma are torch, including the electrode, the tip and the shield cap. The method includes turbulating gas as it flows over the exposed surfaces of the electrode, tip and shield cap to increase turbulence in the hydrodynamic boundary layer of the gas flow, thereby enhancing convective heat transfer. The result of enhanced cooling is improved consumable parts life. For example, to increase the turbulence of the gas flow over the outer surface of the electrode, the plasma arc torch electrode has a roughened, or textured outer surface formed with dimples, axially extending grooves or spiraling grooves formed in the outer surface of the electrode. The inner and outer surfaces of the tip and the inner surface of the shield cap are similarly textured.

    摘要: Generating frequency coherence between a received reference positioning signal carrier component transmitted by at least one reference transmitter and a unique positioning signal carrier component generated by a positioning-unit device. The positioning-unit device receives a reference positioning signal and measures a frequency offset of the reference positioning signal carrier component relative to a common oscillator. Once a frequency offset is measured, the positioning-unit device adjusts a frequency steerable clock by an amount derived from the measured frequency offset. The positioning-unit device then generates a unique positioning signal carrier component at an aligned carrier frequency with the reference positioning signal carrier component. Furthermore, the positioning-unit device continuously adjusts the unique positioning signal carrier component by applying the measured frequency offset to the frequency steerable clock, which is reference to the common oscillator. Subsequently, the frequency of the adjusted unique positioning signal carrier component is aligned with the frequency of said reference positioning signal carrier component.

    摘要: A system and method for providing assistance to a position receiver in a location network consisting of a Global Navigation Satellite System (GNSS) and a synchronized network of positioning-unit devices is disclosed. A positioning-unit device observes the time and frequency of received Global Navigation Satellite System (GNSS) signals relative to the synchronized network of positioning-unit devices. These time and frequency observations are modulated, as assistance data, onto the positioning signals that are broadcast by the positioning-unit devices. A position receiver demodulates the assistance data and analyzes the positioning signals. The position receiver then searches for Global Navigation Satellite System (GNSS) signals in a range responsive to the assistance data and the analysis of the received positioning signals.

    摘要: The present invention discloses a positioning system and method for enabling a roving position receiver to determinist own position. The positioning system comprises a specialized transceiver (hereinafter termed a positioning-unit device) that receives one or more reference positioning signals from other positioning-unit devices and/or other qualified reference positioning signal sources. Each of the received reference positioning signals preferably has a carrier component, a pseudo-random code component, and a data component. The Positioning-Unit Device generates, in response to the received reference positioning signals and their known locations, a unique positioning signal. The unique positioning signal has a carrier component chronologically synchronized to one or more of the carrier components of the received reference positioning signals, a pseudo-random code component chronologically synchronized to one or more of the pseudo-random code components of the received reference positioning signals, and a data component chronologically synchronized to one or more of the data components of the received reference positioning signals. Once a Positioning-Unit Device is chronologically synchronized to a reference transmitter, other Positioning-Unit Devices entering the network can use its transmitted unique positioning signal as a reference positioning signal. The geographical distribution of these chronologically synchronized Positioning-Unit Devices creates a time-coherent network of positioning signals that propagate a reference timebase over a substantial geographical area. The positioning system also includes a roving position receiver. The roving position receiver can generate code-based single point position determinations by making range measurements for each of the received chronologically synchronized pseudorandom code and data components, and can generate carrier-based single point position determinations by making range measurements for each of the received chronologically synchronized carrier components. The roving position receiver can autonomously calculate both code and carrier-based single point position solutions and subsequently calculate its own position without the requirement for differential correction or absolute time accuracy within the network.
