US Patent 7844864 Location based notification system

A location based notification system for a shop having multiple components that are susceptible to a fault event includes an electronic data storage device and a fault event sensor apparatus associated with each susceptible component. The electronic data storage device has identification data for the associated component stored therein. Operators carry a portable device having an electronic data storage device reader and a memory. The fault event sensor apparatus generates fault event data when a fault event occurs in the associated component and transmits the fault event data to the electronic data storage device or the portable device. The data stored in the electronic data storage devices is read with an electronic data storage device reader of the portable device as the operator moves through the shop. The portable device determines whether the electronic data storage device has fault data stored therein, or if fault event data has been stored in the portable device for the component associated with the identification data read from the electronic data storage device.
