Filed:

Sep 27, 2006

Appl. No.:

11/535803

Inventors:

James R. Pierce - Cumming GA, US
Eric H. Walker - Suwanee GA, US
John A. Wahl - Duluth GA, US

Assignee:

L3 Communications Corporation - New York NY

International Classification:

G06F 15/163
G06F 15/80

US Classification:

713 2, 713 1, 712 28, 712203, 714 11, 714 13

Abstract:

A computing device is booted in a manner that enables a software application to begin execution with minimal delay. When the device is powered up, a first processor system begins booting under control of a first operating system, and a second processor system begins booting under control of a second operating system. The first operating system is of a type that generally takes longer to complete booting than the second operating system. As soon as the second processor system has booted up, it begins controlling execution of a software application. Then, when the first processor system has booted up, control over the software application is transferred from the second processor system to the first processor system.

International Classification:

G06F 17/00

US Classification:

701001000

Abstract:

A mobile computing system for a motor vehicle includes a mobile computing device, which can be mounted in the trunk or other convenient location, and a suitable user interface system, such as a display screen, keyboard, etc., mounted in the vehicle cabin. The computing device can accommodate user-removable, plug-in electronic modules that perform specialized processing, communications, control or other specialized tasks relating in some way to the vehicle mission or purpose. The power supply can similarly be modular. For example, individual power supply modules can plug into power supply bays, each of which services a group of electronic modules.

Appl. No.:

11/419151

Inventors:

James R. Pierce - Cumming GA, US
Eric H. Walker - Suwanee GA, US
John A. Wahl - Duluth GA, US

International Classification:

G02F 1/1335

US Classification:

349114

Abstract:

A transflective display device for ground vehicles, such as police, fire and ambulance vehicles, has display electronics and a transflective liquid crystal display (LCD). The backlight lamp of the transflective LCD is brighter than those of common transmissive LCDs to facilitate viewing in the changing light conditions experienced by such vehicles.

International Classification:

G06F 9/44

US Classification:

719329

Abstract:

The adverse impact of system abnormalities, such as crashes or other failures or problems, is minimized by switching control of a computing device from a first operating system to a second operating system in the event a system abnormality is detected. For example, if a system abnormality causes a processor system under control of the first operating system to crash, another processor system under control of a second operating system can take over. An application program that was executing under control of the first operating system when the crash or other abnormality occurred can continue functioning under control of the second operating system.
