Title: Innovations of Jeffrey A. Chapman
Introduction
Jeffrey A. Chapman is a notable inventor based in Phoenix, AZ, with a remarkable portfolio of 9 patents. His work primarily focuses on advancements in mobile application data and dialect detection, showcasing his innovative approach to technology.
Latest Patents
Chapman's latest patents include a method for identifying device intersections using geo-temporal mobile application data. This computer-implemented method extracts unique devices identified in a user-defined area of interest (AOI) and generates individual geospatial layers for each device. The layers are derived from metadata containing coordinates and associated timestamps for all available points of the device. By combining these individual layers, a convergence surface of polygonal intersections is produced, indicating where devices have shared additional locations outside the initial AOI. Furthermore, applying the timestamp to the resulting layer with a user-defined time interval generates a probability matrix of association.
Another significant patent involves acquiring an author's geospatial location of origin from text-based media through dialect detection. This method detects the dialect for a specified language using keywords, phrases, patterns, or gestures, identifying the geographical location for the author's origin or area of linguistic influence. The identified geospatial areas can include overarching primary areas of use for the base language, coupled with smaller geographical areas bounded by state, country, region, or societal influence. The method produces a map depicting the probable area of origin or influence, enhancing the understanding of linguistic patterns.
