Patent number: 11591872Abstract: A setting tool having a tool body, a chamber configured to contain a non-explosive fuel configured to generate gas and plasma, a cavity, a bleed sub located between the chamber and the cavity. The bleed sub is configured to bleed pressure from the chamber to the cavity after the non-explosive fuel has been initiated. The setting tool also includes a piston disposed within the cavity oriented to stroke in a first direction after the non-explosive fuel has been initiated. The piston may divide the cavity into an upper volume that may receive the pressure increase from the bleed sub and a lower volume. The setting tool may also include a shaft mechanically connected to the piston within the lower volume of the cavity. The shaft may include a dampening conduit configured to drain a fluid from the lower volume after the non-explosive fuel has been initiated.Type: GrantFiled: January 25, 2021Date of Patent: February 28, 2023Assignee: Robertson Intellectual Properties, LLCInventors: Michael C. Robertson, Douglas J. Streibich, Antony F. Grattan, Roy L. Sparkman, Mark Lancaster

Patent number: 10900309Abstract: A setting tool for deploying a downhole tool within a wellbore is described herein. The setting tool uses an in situ non-explosive gas-generating power source to generate high-pressure gas, which drives a mechanical linkage to actuate the deployment of the downhole tool. According to certain embodiments the non-explosive gas-generating setting tool contains no hydraulic stages and may contain only a single piston. The setting tool may be fitted to provide different stroke lengths and can provide usable power over a greater percentage of its stroke length, compared to setting tools using explosive/pyrotechnic power sources. Methods of using a non-explosive gas-generating setting tool to deploy a downhole tool within a wellbore are also disclosed.Type: GrantFiled: April 1, 2019Date of Patent: January 26, 2021Assignee: Robertson Intellectual Properties, LLCInventors: Michael C.

Patent number: 10720934Abstract: Time-interleaved analog-to-digital converters (ADCs) and related methods are disclosed that are based upon multiplying digital-to-analog converters (MDACs). For one ADC embodiment, a sample-and-hold circuit receives an input signal and outputs a voltage that represents the input signal. An MDAC receives the voltage, outputs an N-bit digital value, and outputs a current that represents the voltage. A phased current generator receives the current and outputs time-interleaved currents that are based upon the current. An array of sub-ADCs receive the time-interleaved currents, and each sub-ADC outputs a digital value. The digital values from the array of sub-ADCs are then combined and to output an M-bit digital value. The N-bit digital value and the M-bit digital value provide a digital conversion output for the ADC.Type: GrantFiled: February 28, 2019Date of Patent: July 21, 2020Assignee: NXP USA, Inc.Inventors: Brandt Braswell, George Kunnen, Mark Lancaster

Patent number: 10581446Abstract: Current controlled multiplying digital-to-analog converters (MDACs) and related methods are disclosed for time-interleaved analog-to-digital converters (ADCs). For one embodiment, a circuit includes an MDAC having an amplifier that converts a voltage to an output current, a variable load that is dependent upon a digital value and that controls the output current from the amplifier, and an array of comparators that receive the voltage and output the digital value to the variable load. The digital value represents at least a portion of a digital conversion of the voltage. Further, the circuit can include a phased current generator that receives the output current and generates time-interleaved currents where each time-interleaved current is a sampled copy of the output current.Type: GrantFiled: February 28, 2019Date of Patent: March 3, 2020Assignee: NXP USA, Inc.Inventors: Brandt Braswell, George Kunnen, Mark Lancaster

Patent number: 10574250Abstract: Digital calibration systems and related methods are disclosed for multi-stage analog-to-digital converters (ADCs). For one embodiment, a multi-stage ADC includes an initial ADC, an additional ADC, and calibration logic. The initial ADC generates an output signal and N-bit digital values that are based upon an input signal. The additional ADC receives the output signal from the initial ADC and generates M-bit digital values that are based upon the output signal. The calibration logic receives the N-bit digital values and the M-bit digital values and generates correction values. The correction values are based upon differences between maximum values and minimum values for M-bit digital values associated with different regions determined by the N-bit digital values. Digital conversion outputs for the multi-stage ADC are provided as combinations of the N-bit digital values and the M-bit digital values corrected with the correction values.Type: GrantFiled: February 28, 2019Date of Patent: February 25, 2020Assignee: NXP USA, Inc.Inventors: Brandt Braswell, George Kunnen, Mark Lancaster

Patent number: 10205307Abstract: Monitoring may be provided. First, data may be received comprising a current location of a point on a span of conductor or a current angle of a section of the span of conductor. Next, a sag may be calculated of the span of conductor based upon the current location of the point on the span of conductor and the current angle of the section of the span of conductor. An alert may then be provided when the calculated sag is outside of a predetermined range for the span.Type: GrantFiled: July 10, 2012Date of Patent: February 12, 2019Assignee: Southwire Company, LLCInventor: Mark Lancaster

Patent number: 9634681Abstract: The embodiments described herein provide analog-to-digital converters (ADCs) and systems and methods for calibrating ADCs, including ADCs with poorly characterized nonlinearities that cannot be effectively calibrated with traditional calibration techniques. In general, the embodiments described herein calibrate by measuring output values from an ADC with a known calibration input values being applied. The measured output values are used to determine localized polynomial interpolants. Each of the determined localized polynomial interpolants is then evaluated at an uncorrected output value, and the evaluated localized polynomial interpolants are then used to generate correction values. These correction values can then be used to calibrate the ADC during later operation. Such a calibration technique can provide effective calibration for a variety of ADCs, including ADCs that use inverter-based voltage-to-current (VI) converters and current-controlled ring oscillators.Type: GrantFiled: July 27, 2016Date of Patent: April 25, 2017Assignee: NXP USA, Inc.Inventors: George R.
