Abstract: The present invention is a hydraulic control apparatus that activates and deactivates a downhole tool, such as a reamer, at a desired downhole location in a borehole. The apparatus includes a piston, a housing, a coil spring, and a guide pin. The piston has a cam portion with a continuous slotted groove. There is a slide member and a force member within the slotted groove so that the piston moves longitudinally and rotationally within the housing according to the guide pin within the slotted groove. At the desired downhole location, drilling fluid pressure passes a pressure threshold to move a front outlet of the piston to an opened position past an end of the housing, while rotating the piston according to the slide member and force member in the slotted groove. The apparatus alternately extends and retracts the reamer by opening and closing the front outlet by hydraulic control.

Abstract: Methods and systems for evaluating robustness of vehicle diagnostics and monitoring. One system includes a memory, a communication interface, and an electronic processor. The electronic processor is configured to access diagnostic event data of a vehicle system. The electronic processor is also configured to determine a RQ variable for the current operation cycle based on a set of maximum debounce levels included in the diagnostic event data and a failure threshold. The electronic processor is also configured to store, in the memory, the RQ variable as RQ data at an end of the current operation cycle. The electronic processor is also configured to transmit, via the communication interface, the RQ data for an external robustness evaluation. The electronic processor is also configured to receive, via the communication interface, an update to the failure threshold based on the external robustness evaluation.

Abstract: The present invention provides a novel process of synthesizing a cathode material. A metal selected from Fe, Mn, Co, Ni, Cu, Zn, Al, Ca, Mg, Ti, V, Cr, Mo or any combination thereof is partially oxidized with an agent such as H3PO4. Then, the metal is fully oxidized with an oxidizing agent such as H2O2. Finally, preparation of the cathode material is completed. The process exhibits numerous technical merits such as less water consumption, less electricity usage, improved product purity, and less usage of base raw materials (e.g. NaOH, Na2CO3, NH3·H2O), among others.

Abstract: An adaptive automobile meter detection method based on character segmentation cascade classifier which processes threshold segmentation, morphology and connected components analysis on the original image; extracts the pointer based on the contour analysis method, establishes a pointer information list; constructs a character segmentation cascade classifier by combining a HOG/SVM character segmentation classifier, a character filter and a CNN digit classifier. The character segmentation cascade classifiers is used to identify the digit character area of the automobile meter. Region analysis is performed to extract tick marks based on the center of the digit character area. The angular position corresponding to the tick mark is determined. The response value corresponding to the pointer is determined by establishing the Newton interpolation linear description relationship between the pointer angle and the response value and then the meter is classified as pass or fail.
