Abstract: Systems and methods for data conversion and migration are disclosed herein. In an embodiment, an improved computer system for data conversion and migration for global firms having offices in a plurality of countries includes a mobile device configured to track time using GPS or continuous activity, a client database, and an application server comprising a processing device and a non-transitory storage medium. The application server is configured to generate a unique project code associated with a linked first client and second client, remotely track time of an employee of a second office using GPS or continuous activity from the employee's mobile device, and generate from a first office a combined bill for the first client and the second client which includes at least one fee based on an amount of the remotely tracked time from the mobile device of the employee of the second office.

Abstract: Systems and methods of using a plurality of global positioning system (“GPS”) devices to execute travel for geographically-diverse groups of travelers traveling for a common purpose are disclosed herein. In an embodiment, a method includes reserving a first travel option for a first user departing from a first airport within a predefined first range of the first GPS location at a first time when the first user is available according to a first digital calendar, and when the first user terminal did not arrive at the first airport on the same day prior to first time or the first GPS device was not subsequently disabled, booking a new first travel option for the first user departing from the first airport at a different first time when the first user is available according to the first digital calendar and notify a second user.

Abstract: The present invention relates to particles comprising a core, in particular a magnetic core, and a first coating of a first shell material, wherein a second coating of a second shell material is applied to the surface of the first coating facing away from the core, the second shell material is different from the first shell material and has a higher refractive index than the first shell material.

Abstract: A releasable pneumatically operated coupling for an industrial drive such as for a grinding mill. A variable speed motor has its output shaft provided with a flange rotating therewith on which are mounted a plurality of radially moveable arcuate elements having friction pads on their radially inner surfaces. An inflatable ring surrounds the arcuate elements and, upon inflation, urges the pads into driving contact with an annular friction surface on a coupling output shaft. The arcuate elements have U-shaped undercuts in the axial torque bar passages therethrough for stress relief. Separate speed sensors on the motor shaft and coupling output shaft provide signals to a comparator which, upon sensing a predetermined speed difference, provide a signal to an electrically operated valve which exhausts air pressure from the inflatable ring to release the coupling.
