Patent number: 8633699Abstract: A method and apparatus includes detecting lightning induced electromagnetic pulses and determining a physical property of an underground structure based on the lightning induced electromagnetic pulses. In some embodiments, an apparatus includes an antenna, a low noise amplifier, a processor, cable, and a transmitter. The antenna includes three substantively perpendicular loops of electrical conductors. The processor is configured to condition the amplified signal. The cable is about 100 meters in length and connects the low noise amplifier to the processor. The transmitter is configured to send conditioned data to a data aggregation system.Type: GrantFiled: August 26, 2010Date of Patent: January 21, 2014Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Ivan Richard Linscott, Timothy Chevalier, Umran S.

Patent number: 8452252Abstract: Techniques for a receiver includes a low noise amplifier, a Q-enhanced bandpass filter on a chip, and an analog to digital converter (ADC) at a sub-sampling speed suitable for an intermediate frequency (IF) signal. In some embodiments, a temperature compensation circuit is included. The receiver has an effective noise level less than 7 dB. In some embodiments a 1-bit ADC is used. In some of these embodiments, one or more switches in the ADC are inverted to cancel charge injection.Type: GrantFiled: May 28, 2010Date of Patent: May 28, 2013Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Carsten Barth, Umran S.

Patent number: 8184033Abstract: Techniques for an analog-to-digital converter (ADC) using pipeline architecture includes a linearization technique for a spurious-free dynamic range (SFDR) over 80 deciBels. In some embodiments, sampling rates exceed a megahertz. According to a second approach, a switched-capacitor circuit is configured for correct operation in a high radiation environment. In one embodiment, the combination yields high fidelity ADC (>88 deciBel SFDR) while sampling at 5 megahertz sampling rates and consuming <60 milliWatts. Furthermore, even though it is manufactured in a commercial 0.25-?m CMOS technology (1 ?m=12?6 meters), it maintains this performance in harsh radiation environments. Specifically, the stated performance is sustained through a highest tested 2 megarad(Si) total dose, and the ADC displays no latchup up to a highest tested linear energy transfer of 63 million electron Volts square centimeters per milligram at elevated temperature (131 degrees C.) and supply (2.7 Volts, versus 2.5 Volts nominal).Type: GrantFiled: May 12, 2010Date of Patent: May 22, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Charles Chang-I Wang, Ivan Richard Linscott, Umran S.

Publication number: 20070250180Abstract: A method and user interfaces are described herein installing a field device as a replacement for a previously installed field device of a same type in a process control system. The disclosed method includes initially specifying a device type commissioning definition that includes a set of device-type specific parameters. A first set of instance-specific configuration parameter values are then stored for a first field device. When replacing the first field device by a second field device of the same type on a process control network, the commissioning definition and the previously stored parameters for the first device are used to automatically configure the second device.Type: ApplicationFiled: April 11, 2006Publication date: October 25, 2007Applicant: Invensys Systems, Inc.Inventors: Scott Bump, Nestor Camino, Vladimir Kostadinov, Charles Piper, Richard Linscott, Johan Tegnell

Publication number: 20070078540Abstract: A compare tool for use in a process control system device configuration environment is described herein. The compare tool, including a graphical user interface for providing comparison results, is utilized in a device configuration environment to compare parameter values from an instance of a field device to corresponding values maintained within an application database. After performing the comparison the utility displays the results on a user interface. More particularly the parameter names and associated values are presented in three columns of the user interface. A first column identifies a parameter within the field device. A second column identifies a previously archived value for the parameter identified in the first column, and a third column identifies a current value, captured from a device instance, corresponding to the parameter identified in the first column.Type: ApplicationFiled: April 11, 2006Publication date: April 5, 2007Applicant: Invensys Systems, Inc.Inventors: Scott Bump, Nestor Camino, Vladimir Kostadinov, Charles Piper, Richard Linscott, Johan Tegnell
