Wireless bar code symbol driven portable data terminal (PDT) system for running application programs on an operating system emulated on a virtual machine
First Claim
1. A wireless portable data terminal (PDT) system for use and communication with a base station by way of an electromagnetic-based radio-frequency (RF) 2-way digital data communication link, said wireless PDT system comprising:
- a hand-supportable housing;
a rechargeable battery supported within said hand-supportable housing;
a data capture engine mounted within said hand-supportable housing, for optically capturing data, about objects optically encoded in information structures such as bar code symbols;
a LCD panel integrated with said hand-supportable housing;
a micro-computing platform mounted within said hand-supportable housing, and capable of (i) running/executing application programs on a first kind of operating system (OS1) that is emulated on a virtual machine that is supported on a second kind of operating system (OS2) so that the application programs can be developed on developer computers-running the first kind of operating system OS1, and (ii) supporting a graphical user interface (GUI) on said LCD panel for graphically displaying and manipulating documents; and
a user control console having a manual data-entry structure for manually entering data into said documents.

Abstract
The wireless PDT of the present invention employs a “display-on bottom” design which places the unit perfectly centered in the hand of the operator, allowing for the best possible viewing as well as providing comfortable single-handed operation. The high-resolution LCD display allows the PCT to show sharp, clear bitmap images while supporting all Windows-recognized font types and sizes. With the auto back-lit feature, the brightness adjusts automatically making the screen easy to read in all light conditions. The PDT is designed for support within the download/charger cradle of a base station which interfaces with a host system using either USB or RS232 interface. Two standard ‘AA’ or rechargeable Li-Ion batteries provide more than 100 hours of operation. In addition, the PDT comes standard with 2 MB of RAM providing enough memory to store over 100,000 records. Applications for the PDT can be developed using a novel integrated development and deployment environment (IDE) which contains an easy-to-use Windows-based application generator and download utilities. For advanced programming, developers can choose to write software using an advanced application generator or ‘C’ programming application generator which provides the developer with simple programming and fast setup. Further enhancements available in the application generator include drag and drop icons, time/datestamp, battery level indicator and variable fonts, giving the developer the ability to create custom screen layouts.
