Computer with high intensity screen
View Patent ↗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.
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, wherein the display has a brightness of at least 500 NIT; and
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.

the coolant passage has a first portion that is thermally exposed to the sealed compartment, and a second portion disposed outside of the sealed compartment,
the exchanger further comprises:
a heat sink thermally coupled to the second portion, and
a fan supported by the case and disposed outside of the sealed compartment, the fan being positioned to direct a flow of ambient air over the heat sink so as to facilitate heat transfer from the heat sink to the ambient air.
3. The computer of claim 2 , wherein:
the heat sink comprises a first heat sink, and
the computer further comprises a second heat sink thermally coupling the display to the first portion.
4. The computer of claim 1 , further comprising a heat sink thermally coupling the display to the coolant passage.
5. The computer of claim 1 , wherein the chipset comprises a processor, and the computer further comprises a heat sink thermally coupling the processor to the coolant passage.
6. 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.
7. The computer of claim 1 , wherein the display comprises a screen with a viewable area of at least 20 square inches.
8. The computer of claim 1 , wherein the display has a brightness of at least 600 NIT.
9. The computer of claim 8 , wherein the display has a brightness of at least 700 NIT.
10. 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.
11. The computer of claim 1 , wherein the sealed compartment is fan-less.
12. The computer of claim 2 , wherein the case comprises a ventilated plastic cover that covers the fan.
13. The computer of claim 12 , wherein a portion of the case comprises magnesium.
14. The computer of claim 2 , wherein:
a portion of the case separates the sealed compartment from the outside of the sealed compartment;
the coolant passage extends through an opening in the portion of the case; and
the computer further comprises a sealing structure that forms a seal between the coolant passage and the opening.
15. The computer of claim 14 , wherein the sealing structure comprises a gasket.
16. The computer of claim 14 , wherein the sealing structure comprises a silicone.
17. The computer of claim 1 , wherein the display has a brightness of between 500 and 1000 NIT.
18. The computer of claim 1 , wherein a portion of the case comprises aluminum, titanium, or magnesium.
19. The computer of claim 1 , wherein the case comprises a magnesium main upper structural portion.
20. The computer of claim 1 , wherein the case comprises a magnesium main lower structural portion.
21. The computer of claim 1 , wherein an exterior portion of the case comprises aluminum, titanium, or magnesium.
22. The computer of claim 1 , wherein an exterior portion of the case comprises magnesium.
23. The computer of claim 1 , wherein a magnesium portion of the case separates the sealed compartment from the ambient air outside of the sealed compartment.
24. The computer of claim 1 , wherein a portion of the case separates the sealed compartment from the ambient air outside of the sealed compartment, and wherein the portion of the case comprises aluminum, titanium, or magnesium.
25. A tablet computer comprising:
a case defining a sealed compartment;
a chipset disposed in the sealed compartment; and
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.
26. The computer of claim 25 , wherein the display has a brightness of at least 600 NIT.
27. The computer of claim 26 , wherein the display has a brightness of at least 700 NIT.
28. The computer of claim 25 , wherein the display comprises a screen with a viewable size that is at least 8 inches in the diagonal direction.
29. The computer of claim 25 , wherein the display comprises a screen with a viewable area of at least 20 square inches.
