Abstract: Systems and methods for generating optical character recognition (OCR) models configured to identify characters from a variety of different documents. The OCR models are based on a base model. One or more outside models can be tested to determine their effectiveness in supplementing the base model. When an outside model is effective it is incorporated into the base model. Generations of base models can be created that provide for additional functionality that is not present in the preceding model. A family of the generations of base models is maintained.

Abstract: Methods, devices, and systems for detecting incapacitation and location using nodes are described herein. One system for detecting incapacitation and location using nodes can include an impact sensor, and a node including a memory and a processor to execute executable instructions stored in the memory to determine an incapacitating event has occurred via the impact sensor, determine a location of the node using a plurality of nodes, where the plurality of nodes include the node, and transmit the incapacitating event and the location of the node to an external server.

Abstract: A location system includes multiple master nodes located at corners of a coverage area. At least two master nodes are located on one edge of the coverage area and receive signals from a slave node within the coverage area. The at least two master nodes calculate a distance to the slave node and a location of the slave node within the coverage area.

Abstract: Devices, methods, systems, and computer-readable media for tracking a location of an object are described herein. One or more embodiments include a receive element to receive wireless transmissions from a plurality of nodes including range data of an object from each of the plurality of nodes, a position calculator to convert the range data to distance measurements of the distance of each of the plurality of nodes to the object, and a transmit element to transmit the distance measurements to a command node.

Abstract: Devices, methods, systems, and computer-readable media for calculating a distance and direction from a location tracker to a location of a node are described herein. One or more embodiments include a transmit element to transmit a search command for a first node to one or more nodes, a receive element to receive wireless transmissions from the one or more nodes including range data between the location tracker and each of the one or more nodes, and a time of flight (ToF) ranging calculator to convert the range data to a distance measurement from the location tracker to the first node.

Abstract: A fall protection harness includes a computer processor, an optical transmitter, and an optical receiver coupled. The optical transmitter and the optical receiver are optically coupled. Upon damage to the fall protection harness, the optical coupling between the optical transmitter and the optical receiver is broken, the computer processor senses the break in the optical coupling between the optical transmitter and the optical receiver; and the computer processor generates a signal indicating the damage.

Abstract: A fall protection harness or fall protection static line includes one or more straps, an electrical sensing device coupled to the one or more straps, a computer processor coupled to the electrical sensing device, and a transmitter coupled to the computer processor. The one or more straps are made up of an electrically non-conducting thread and an electrically conducting thread. The electrically non-conducting thread and the electrically conducting thread are intertwined, or the electrically conductive thread is intertwined with itself. The electrical sensing device detects a disruption in current in the electrically conducting thread, a disruption in voltage in the electrically conducting thread, or a change in resistance in the electrically conducting thread, which indicates damage to the fall protection harness or a fall by a person wearing the fall protection harness.
