Abstract
A portable data terminal including a processor having an instruction set architecture and data storage means configured to store a plurality of operating systems and a virtual machine monitor application program configured to receive at least one instruction from each operating system, communicate with the processor according to the instruction set architecture, and switch operating system access to the processor upon receipt of an electrical signal representing an event.
Claims18
A portable data terminal, comprising:
- a processor having an instruction set architecture;
- an imaging assembly;
- an illumination assembly;
- and
- data storage means configured to store:
- a plurality of operating systems;
- a virtual machine application program configured to receive at least one instruction from each operating system, communicate with the processor according to the instruction set architecture, and switch operating system access to the processor upon receipt of an electrical signal representing an event;
- a scan driver application program configured to communicate with the imaging and illumination assemblies;
- and
- a decoder application program;
- wherein the electrical signal can be communicated based on user interaction with a trigger.
8 more elements
A portable data terminal, comprising:
- a user interface device;
- a processor having an instruction set architecture;
- data storage means configured to store:
- a first operating system configured to communicate with the processor according to the instruction set architecture;
- a first application program configured to communicate with the first operating system;
- a second operating system;
- a second application program configured to communicate with the second operating system;
- and
- a virtual machine application program configured to receive at least one instruction from
- the second operating system and communicate with the first operating system based on the at
- least one instruction;
- and
- wherein the portable data terminal is configured to switch operating systems upon user interaction with the user interface device;
- wherein the electrical signal can be communicated based on user interaction with a trigger.
