    Abstract: Methods and apparatuses for master safety lockout systems are provided herein. In some embodiments, a master safety lockout system is provided which can include a control data module and can lock out the operation of equipment for any of: operator lacking required credentials, geo-fencing restrictions, emergency shutdown procedures, remote disablement, and/or disablement for servicing. In some embodiments, a Near Field Communication (NFC) Module, a database, and a communications system can be used. By requiring operators to scan their NFC access device to have the qualifications checked before being authorization to start equipment (mobile and stationary). Unqualified individuals can be prevented from causing injury or damage. Interconnecting multiple pieces of equipment can also provide for the ability to remotely control the operation of the equipment, allowing the implementation of the master safety lockout system.

    Abstract: Disclosed in some examples are methods, systems, devices, and machine readable mediums which utilize a new GNSS processing method called cloud-offloaded, device-acquisition GPS (CODA-GPS). Rather than offloading both the acquisition and localization processes as was done with CO-GPS, the computing device performs satellite acquisition itself and sends the acquisition data to the cloud for localization. Also disclosed in some examples, are methods, systems, and machine-readable mediums which provide for reduced acquisition calculations for devices. The reduced acquisition time is achieved through visible satellite prediction techniques that allows for searching only a limited set of satellites.

    Abstract: Some implementations provide low power reduced sampling of global positioning system (GPS) locations. A server may be configured to assist a mobile device in determining a location from a plurality of small GPS signal chunks and corresponding time stamps. For instance, the server may identify a set of satellites from each of the GPS signal chunks and by comparing the set of satellites for each of the GPS signal chunks to each other to determine a second set of satellites. The server may then estimate a location of the mobile based on the second set of satellites.

    Abstract: An optimum measurement subset with a specified number n of elements is generated from a set of N > n weighted input global navigation satellite system (GNSS) measurements. A group of trial measurement subsets is generated by removing a different individual weighted input GNSS measurement from the set. A value of accuracy criterion for a target parameter is calculated for each trial measurement subset, and the trial measurement subset with the minimum value of accuracy criterion is selected. A new group of trial measurement subsets is generated by removing a different individual weighted GNSS measurement from the previously selected trial measurement subset. A value of accuracy criterion is calculated for each new trial measurement subset, and a new trial measurement subset with the new minimum value of accuracy criterion is selected. The process is repeated until the selected trial measurement subset has the specified number n of elements.
