Publication number: 20210281209Abstract: A system obtains respective measurements of relevant electrical parameters of an electrical motor of a vehicle such as a locomotive during operational stages of the motor and a system driven thereby. Based on the respective measurements, the monitoring system then determines respective electrical patterns corresponding to the operational stages. Next, the monitoring system compares the respective electrical patterns corresponding to the operational stages with respective baseline electrical patterns modeled for the operational stages to yield a comparison. Then, the monitoring system determines a status of any of the motor components, as well as those of the system driven thereby, based on a comparison between baseline and observed operating parameters. Trend pattern monitoring is used to eliminate storing massive volumes of trend data by capturing and characterizing the important moments when data values change in a significant manner.Type: ApplicationFiled: February 23, 2021Publication date: September 9, 2021Inventors: Mark Wayland Vinson, Raymond M.

Patent number: 9337807Abstract: Systems and methods for equalizing an output driver circuit based on information from calibration of the output impedance of the driver circuit are disclosed. Settings that result from the calibration are referred to as calibration codes. The output driver circuit includes multiple pull-up elements that are enabled or disabled to produce a desired output impedance when the output is high and multiple pull-down elements that are enabled or disabled to produce the desired output impedance when the output is low. The number of pull-up elements that are enabled and the number of pull-down elements that are enabled is set by calibration. The results of the calibration (i.e., the number of enabled elements for the pull-up and the number of enabled elements for the pull-down) are used to set controls for an amount of pre-emphasis and/or to set controls for output slew rates.Type: GrantFiled: September 30, 2014Date of Patent: May 10, 2016Assignee: QUALCOMM INCORPORATEDInventors: Timothy Mowry Hollis, Thomas Clark Bryan, Mark Wayland

Patent number: 9166565Abstract: An output driver configured to drive an output node includes a pull-down section having a plurality of legs and a pull-up section having a plurality of pull-up legs. Each leg and pull-up leg includes a data path and a calibration path. The data paths in the pull-down section are configured to conduct to ground responsive to an assertion of a complement data output signal whereas the data paths in the pull-up section are configured to conduct to a power supply node responsive to a de-assertion of the complement data output signal.Type: GrantFiled: October 17, 2013Date of Patent: October 20, 2015Assignee: QUALCOMM IncorporatedInventors: Michael Joseph Brunolli, Mark Wayland

Patent number: 9111848Abstract: A control circuit generates data signals and configuration commands that are provided to an interface circuit. The interface circuit includes a configuration circuit that generates configuration signals according to the configuration commands and a drive component that generates interface signals according to the data signals. The interface signals are generated with a drive characteristic determined according to the configuration signals applied to configuration devices that selectively activate a configuration of drive devices. A diagnostic circuit is coupled to the control circuit and the interface circuit and is configured to receive a test state indication and acquire a corresponding portion of the configuration signals. The diagnostic circuit compares the test state indication and the portion of the configuration signals to diagnose a stuck-at fault condition within a faulty configuration circuit and propagate a fault indication to the control circuit.Type: GrantFiled: May 7, 2014Date of Patent: August 18, 2015Assignee: QUALCOMM IncorporatedInventors: Kenneth Dubowski, Thomas Clark Bryan, Mark Wayland

Patent number: 9083330Abstract: An output driver for driving a data output signal through an output pad includes a plurality of calibration paths to calibrate the impedance of the output pad. Depending upon the desired impedance, various ones of the calibration paths are selectively coupled to the output pad. Each selected calibration path adds a capacitive load to a data node, which affects the slew rate for the data output signal. To adjust the capacitive load on the data node in light of the calibration path selections, the output driver includes a plurality of selectable capacitors corresponding to the plurality of calibration paths. If a calibration path is not selected to couple to the output pad, the corresponding selectable capacitor capacitively loads the data node.Type: GrantFiled: October 17, 2013Date of Patent: July 14, 2015Assignee: QUALCOMM IncorporatedInventors: Michael Joseph Brunolli, Mark Wayland
