Abstract

A computer includes various features that improve its functionality and/or ease of use. A modular electronics cartridge that includes a piston seal and opposed-direction latches removably engages a cartridge bay of the computer. A high intensity touch-screen display and a high power processor are disposed in a sealed compartment of the computer, and a remote heat exchanger is used to cool the sealed compartment. An interface converter/adapter converts a standard mini-PCI Express slot into a specialized mini-PCI Express slot with voice capabilities. SIM and microSD card slots mount to a pivoting door on the computer such that opening the door provides easier access to the card slots.

Claims

1. A tablet computer comprising:

a case defining a sealed compartment;

a chipset disposed in the sealed compartment;

a touch-screen display supported by the case and electrically connected to the chipset, the display facing outward away from the case, a rear side of the display being disposed in the sealed compartment;

an active coolant heat exchanger supported by the case, the exchanger comprising a coolant passage containing a coolant whose flow is configured to carry heat out of the sealed compartment and into an ambient air outside of the sealed compartment; and

an electronics interface electrically connected to the chipset,

wherein the display has a brightness of at least 500 NIT.

2. The computer of claim 1, wherein the display comprises a screen with a viewable size that is at least 8 inches in the diagonal direction.

3. The computer of claim 1, wherein the display comprises a screen with a viewable area of at least 20 square inches.

4. The computer of claim 1, wherein the display has a brightness of at least 600 NIT.

5. The computer of claim 4, wherein the display has a brightness of at least 700 NIT.

6. The computer of claim 1, wherein the display comprises first, second, and third user-selectable operating modes, the first operating mode comprising a touch only mode, the second operating mode comprising a stylus only mode, and the third operating mode comprising a dual mode with the stylus operation taking priority over touch operation.

7. The computer of claim 1, wherein the sealed compartment is fan-less.

8. The computer of claim 1, wherein the electronics interface comprises a PCI-X slot, a mini-PCI Express slot, a USB interface, a speaker port, a microphone port, a docking port interface, a SIM card interface, or a memory card interface.

9. A tablet computer comprising:

a case defining a sealed compartment;

a chipset disposed in the sealed compartment;

a touch-screen display supported by the case and electrically connected to the chipset, the display facing outward away from the case, a rear side of the display being disposed in the sealed compartment, wherein the display has a brightness of at least 500 NIT; and

an electronics interface electrically connected to the chipset.

10. The computer of claim 9, wherein the display has a brightness of at least 600 NIT.

11. The computer of claim 10, wherein the display has a brightness of at least 700 NIT.

12. The computer of claim 9, wherein the display comprises a screen with a viewable size that is at least 8 inches in the diagonal direction.

13. The computer of claim 9, wherein the display comprises a screen with a viewable area of at least 20 square inches.

14. The computer of claim 9, wherein the sealed compartment is fan-less.

15. The computer of claim 9, wherein the electronics interface comprises a PCI-X slot, a mini-PCI Express slot, a USB interface, a speaker port, a microphone port, a docking port interface, a SIM card interface, or a memory card interface.
