Patent Title
External Hollow Antenna

Patent Number & Issued Date
US 9,995,132
June 12, 2018

Inventor Names
Michael F. Gard*, Brian K. Bailey, Richard F. Sharp
*Indicates IMS member

Abstract
A beacon assembly located at a downhole end of a drill string proximate a boring tool. The beacon assembly transmits data to an above-ground receiver. The beacon has a housing with a housing wall located between its sensors, such as gradiometers, accelerometers, and other orientation sensors, and an antenna assembly. The antenna assembly has a protective covering made of electromagnetically transparent material.

*Indicates IMS member

Abstract
We disclose a chemical sensing device for detecting a fluid. The sensing device comprises: at least one substrate region comprising at least one etched portion; a dielectric region formed on the at least one substrate region, the dielectric region comprising at least one dielectric membrane region adjacent to the at least one etched portion; an optical source for emitting an infra-red (IR) signal; an optical detector for detecting the IR signal emitted from the optical source; one or more further substrates formed on or under the dielectric region, said one or more further substrates defining an optical path for the IR signal to propagate from the optical source to the optical detector. At least one of the optical source and optical detector is formed in or on the dielectric membrane region.

Patent Title
Two-Input Amplifier

Patent Number & Issued Date
US 9912304
Issued March 6, 2018

Inventor Names
Alexandru A. Ciubotaru*, Christoph M. Steinbrecher
*Indicates IMS member

Abstract
A two-input amplifier is disclosed. The amplifier can include an amplification path for a first input signal that can have adjustable flatness or high-frequency peaking, and an amplification path for a second input that can be substantially independent of the frequency-shaping aspect of the first-input path. The first-input amplification path can include an operational amplifier as an active device and a plurality of passive elements for frequency shaping. The second-input amplification path can include a device that injects its output current into a node of the first path. The signals of the two paths can be combined and appear substantially independently of each other at the output of the amplifier.

Patent Title
Self-biased Multiple Cascode Current Mirror Circuit

Patent Number & Issued Date
USA  9,874,893
January 23, 2018

Inventor Names
Alexandru A. Ciubotaru

Abstract
A self-biased cascode current mirror/scaler circuit can include a bias FET biased with an input current to generate a gate-source voltage, which can be divided by a bias circuit into a first voltage component (e.g., at a threshold voltage) and a second voltage component (at a FET drain-source saturation voltage or edge of saturation voltage). An input FET of the current mirror/scaler circuit can receive approximately the input current or a function thereof. A gate of the input FET can be biased at the first voltage component in sum with a FET drain-source saturation voltage or edge of saturation voltage of the input FET. A gate of the output FET can be connected to the gate of the input FET. A gate of a cascode FET in series with the output FET can be biased at the first voltage component in sum with the second voltage component in sum with the FET drain-source saturation voltage or edge of saturation voltage of the input FET. Multiple cascode FETs, multiple output stages, high frequency bypass capacitors, and lowpass filters are also described.
