    摘要: An analysis system includes a degassing cell, at least one first valve, and at least one second valve. The at least one first valve is fluidly coupled with a top of the degassing cell, the at least one first valve configured selectably connect the degassing cell to a displacement gas flow and to a vacuum source. The at least one second valve is fluidly connected with a lateral side of the degassing cell and separately fluidly connected with a bottom of the degassing cell. The at least one second valve is selectably coupled with any of a source of a sample-carrying fluid, a transfer line configured to deliver a sample to an analysis device, or a waste output.

    摘要: A zero trust industrial control system is disclosed herein. The industrial control system includes a plurality of industrial elements (e.g., modules, cables) which are provisioned during manufacture with their own unique security credentials. A key management entity of the zero trust industrial control system monitors and manages the security credentials of the industrial elements starting from the time they are manufactured up to and during their implementation within the industrial control system for promoting security of the industrial control system. An authentication process, based upon the security credentials, for authenticating the industrial elements being implemented in the industrial control system is performed for promoting security of the industrial control system. In one or more implementations, all industrial elements of the zero trust industrial control system are provisioned with the security credentials for providing security at multiple (e.g., all) levels of the system.

    摘要: A filter unit for use With a filtrating fluid flow system is configured to receive a flow of a fluid containing particulate matter. The filter unit comprises a filter structure formed of a filter material configured to at least partially filter the particulate matter from the flow of fluid. The filter unit further comprises an entry plate located proximate the filter structure entrance. The filter structure and the entry plate together define a fluid cavity within the filter unit, the entry plate having at least one orifice defined therein through which the flow of fluid can pass into the fluid cavity. The orifice is configured to form a choke, creating a Venturi effect for temporarily increasing the velocity of the flow of fluid through the entry plate and within the fluid cavity, and onto the filter material.

    摘要: A pitch data processing system of a horizontal directional drilling system can include a sonde, an offset and range calibration unit, a pitch speed limiter, and a low pass filter. The sonde can include an accelerometer configured to measure and output a raw pitch signal. The offset and range calibration unit can receive and process the raw pitch signal and output a calibrated pitch signal. The pitch speed limiter can receive the calibrated pitch signal. The pitch speed limiter is configured to set upper and lower pitch change speed limits. The pitch speed limiter can yield a speed-change limited pitch signal. The low pass filter can receive the speed-change limited pitch signal and attenuate the received speed-change limited pitch signal above a selected cutoff frequency of the low pass filter, the low pass filter configured to output an adjusted pitch signal.

    摘要: An electromagnetic connector is disclosed that is configured to form a first magnetic circuit portion comprising multiple coils disposed about a first core member. The electromagnetic connector is configured to mate with a second electromagnetic connector that is configured to form a second magnetic circuit portion comprising a coil disposed about a second core member. When the electromagnetic connector is mated with the second electromagnetic connector, the first core member and the second core member are configured to couple the multiple coils of the electromagnetic connector to the coil of the second electromagnetic connector with a magnetic circuit formed from the first magnetic circuit portion and the second magnetic circuit portion. The magnetic circuit is configured to induce a signal in a first coil of the multiple coils and the coil of the second electromagnetic connector when a second coil of the multiple coils is energized.
