ABSTRACT:
A configurable electronic work slate unit includes a customizable array of data devices and input/output devices which are selectively integrated in a compact and highly ergonomic structure. Increased operator productivity is accomplished by use of several possible user interface media including a multi-function display and input/output unit including a digitizer, position sensitive screen, and video display panel. Selectively integratable user interface components include a bar code scanner, RF modulator for radio frequency communication, modem, audio input/output, as well as the multi-purpose display. All components are integrated by use of a handle unit or module docking assembly which can house a battery as well as removable modules in a manner so as to minimize operator fatigue and discomfort, as well as enhance productivity. Configuration, reconfiguration and updating of work slate units by choice and selection of removable modules, from a variety of different types of modules, is enhanced by utilization of standardized interfaces which are intercoupled to a common signal bus. The bus configuration in combination with a bus controller functions as an intelligent bus capable of identifying types of removable modules and configuring communication protocols for operation with different types of removable modules.
