Abstract: A ringout detection system may receive a plurality of surface weight-on-bit (SWOB) measurements from a surface weight-on-bit (WOB) sensor and a plurality of downhole weight-on-bit (DWOB) measurements from a downhole WOB sensor. A ringout detection system may identify a decrease in a WOB ratio between the plurality of SWOB measurements and the plurality of DWOB measurements. A ringout detection system may determine that the decrease in the WOB ratio exceeds a WOB ratio threshold. A ringout detection system may identify that ringout has occurred at the reamer based at least in part on the decrease in the WOB ratio.

Abstract: A computer-implemented method and system for identifying an object in an area of interest. The area of interest is enclosed by a boundary comprising a plurality of line segments extending between vertex points. A reference point relative to the area of interest and a reference direction from the reference point are determined and used to determine a vertex angle of each vertex point. The reference point and reference direction also are used to determine an object angle of the object from location information identifying a location of the object. The object angle and the vertex angles are used to identify a number of line segment crossings in the plurality of line segments. An indicator is generated to indicate whether the object is in the area of interest based on the number of line segment crossings.

Abstract: Techniques are provided for verifying Access Points (APs) using crowd sourcing. In one example, a STA establishes a first non-verified connection, based on security material, with a source AP in a wireless infrastructure. A target AP in a wireless infrastructure obtains an indication that the STA is attempting to establish a second non-verified connection with the target AP. In response, the target AP establishes the second non-verified connection based on the security material.

Abstract: Techniques for binarization and extraction of information from image data are disclosed. The inventive concepts include independently binarizing portions of the image data on the basis of individual features, e.g. per connected component, and using multiple different binarization thresholds to obtain the best possible binarization result for each portion of the image data.

Independently binarized portions may be assembled into a contiguous result. In one embodiment, a method includes: identifying a region of interest within a digital image; generating a plurality of binarized images based on the region of interest using different binarization thresholds; and extracting data from some or all of the plurality of binarized images. The extracted data includes connected components that overlap and/or are obscured by unique background.
