Abstract: This disclosure relates to a sensor-based monitor for movements of workers. Multiple inertial sensors are attached to different body parts of the workers. A mobile device application receives the inertial movement data from the sensors and identify movement patterns by applying a trained machine learning model to the inertial movement data. The application then determine for each movement pattern an amount of time that movement pattern occurred and accessing a database to retrieve stored data on an association between the identified movement patterns and injuries. The application calculates a risk value indicative of a risk of injury of the worker as a result of performing the identified movement pattern for the determined amount of time and produces a report detailing the risk value for each of multiple risk categories.

Abstract: An embossing method for marking braille numbers on currency notes wherein the embossing device used by the present invention has a universal female die permanently affixed to its upper platen and interchangeable lower counters for use in marking labels to affix to currency notes or for embossing braille markings directly on currency notes. The universal female die would collectively incorporate indentations for the braille markings of all of the currency denominations commonly used, such as one dollar bills, five dollar bills, ten dollar bills, twenty dollar bills, fifty dollar bills, and one hundred dollar bills. The interchangeable lower counters could comprise braille images placed on a rotating disk or individual counter units. Applications could include, but are not limited to, marking United States currency notes, the currency notes of other nations, and currency note substitutes such as checks, coupons, travelers checks, and money orders for the benefit of visually challenged people.
