Patent number: 9945800Abstract: A fuel gas composition sensing system may include a remotely controllable valve, with the valve including a gas inlet port, a gas outlet port, an internal chamber, and at least one actuating mechanism configured for successively opening the inlet port to allow gas to enter the internal chamber, closing the inlet port and the outlet port to retain the gas in the internal chamber for a period of time, and opening the outlet port to release the gas from the internal chamber. One or more micro-sensors may be mounted in the internal chamber of the valve, with each of the micro-sensors being configured to sense a characteristic of a gas introduced into the internal chamber of the valve.Type: GrantFiled: July 23, 2015Date of Patent: April 17, 2018Assignee: Caterpillar Inc.Inventor: Douglas Alexander Rebinsky

Patent number: 9377287Abstract: A method of configuring an eddy current detector to measure a thickness of a coating on a substrate includes measuring an impedance of the coated substrate, and establishing an impedance plane plot using a computer. The method may also include determining a rotation angle. The rotation angle may be an angle of rotation of the impedance plane plot that will make the inductive reactance component of the impedance substantially insensitive to substrate electrical conductivity within a coating thickness range. The method may further include establishing a calibration curve that is substantially insensitive to substrate electrical conductivity using the rotation angle. The calibration curve may be a curve that relates the inductive reactance component of the impedance to coating thickness.Type: GrantFiled: November 17, 2011Date of Patent: June 28, 2016Assignee: Caterpillar Inc.Inventors: Yong Tian, Douglas Alexander Rebinsky, Christopher Anthony Kinney, Kegan Luick

Patent number: 9354220Abstract: A fuel quality sensor is provided for use with an engine system. The fuel quality sensor may have a single sensing element configured to sense a thermodynamic property of an unknown mixture of gaseous fuel, and a heating element configured to increase a temperature of the unknown mixture of gaseous fuel at the single sensing element to multiple different temperature levels. The fuel quality sensor may also include a microprocessor configured to calculate a fuel parameter of the unknown mixture of gaseous fuel as a function of only the thermodynamic property sensed at the multiple different temperature levels.Type: GrantFiled: September 27, 2013Date of Patent: May 31, 2016Assignee: Caterpillar Inc.Inventor: Douglas Alexander Rebinsky

Patent number: 9169623Abstract: A wear monitoring system is disclosed for use with a track type machine. The wear monitoring system may have at least a first radius sensor configured to generate a first signal indicative of a change in radius of at least one idler wheel, and a displacement sensor configured to generate a second signal indicative of a change in displacement of a track tensioning actuator. The wear monitoring system may also have a controller in communication with the first radius sensor and the displacement sensor. The controller may be configured to determine wear of a track link guided by the at least one idler wheel and tensioned by the track tensioning actuator based on the first and second signals.Type: GrantFiled: April 25, 2013Date of Patent: October 27, 2015Assignee: Caterpillar Inc.Inventor: Douglas Alexander Rebinsky

Patent number: 8653839Abstract: A sensor is disclosed for determining a sulfur concentration in a liquid, such as a liquid fuel. The sensor includes a substrate that is at least partially coated with zinc oxide and, more specifically, zinc oxide microstructures. The zinc oxide microstructures have a crystal lattice structure that is oriented in the (002) plane, are oxygen-deficient and have a rod-like microstructure. If the substrate is conductive, it may be connected directly to a working electrode which is connected to a potentiometer which, in turn, is connected to a reference electrode. If the substrate is non-conductive, the conductive layer can be deposited on the substrate prior to deposition of the zinc oxide to form a working electrode. An application of a constant current (or voltage) to either electrode will result in a voltage across (or current flow between) the working and reference electrodes.Type: GrantFiled: January 20, 2012Date of Patent: February 18, 2014Assignee: Caterpillar Inc.Inventors: Douglas Alexander Rebinsky, Orhan Altin, Yong Tian, Ryan A.
