18. A ring attachment device, comprising:
a non-magnetic shelf; and
a pair of electromagnets that are positioned along each side of the shelf,
wherein said shelf includes a width that is suitable for receiving one or more expandable rings having embedded magnets and a central opening that is sized to fit a plurality of medical scopes having different diameters, and
said electromagnets function to engage the embedded magnets to transition the one or more expandable rings between an expanded and a non-expanded state.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A system for cooling an electronic display having a posterior display surface and contained within a housing, the system comprising:
a constricted convection plate placed posterior to the posterior display surface and covering the majority of the posterior display surface;
a channel formed between the constricted convection plate and the posterior display surface; and
a fan placed to draw ambient air through the channel;
wherein the constricted convection plate thermally isolates electrical components from the posterior display surface.
2. The cooling system from claim 1 wherein:
the posterior display surface comprises the rear surface of a backlight assembly.
3. The cooling system from claim 1 wherein:
the constricted convection plate is substantially parallel to the posterior display surface.
4. The cooling system from claim 1 further comprising:
at least one bracket which connects the posterior display surface with the constricted convection plate.
5. The cooling system from claim 1 further comprising:
a heat sink placed within the channel.
6. A liquid crystal display (LCD) comprising:
a liquid crystal stack;
a backlight assembly behind the liquid crystal stack and comprising:
a printed circuit board (PCB) having front and back sides;
a plurality of LEDs mounted on the front side of the PCB;
a posterior surface on the rear side of the PCB which does not have any electronic devices attached directly thereto;
a constricted convection plate placed behind the posterior surface of the PCB; and
a fan positioned to draw air between the constricted convection plate and the posterior surface.
7. The LCD from claim 6 further comprising:
at least one bracket which connects the posterior surface with the constricted convection plate.
8. The LCD from claim 6 further comprising:
a heat sink placed between the constricted convection plate and the posterior surface of the backlight assembly.
9. The LCD from claim 6 further comprising:
a housing which contains the liquid crystal stack, backlight assembly, constricted convection plate, and fan; and
an entrance aperture within the housing which permits external ambient air to enter the housing and flow between the constricted convection plate and the posterior surface of the PCB.
10. The LCD from claim 6 further comprising:
a plurality of access apertures on the constricted convection plate.
11. An electronic display assembly comprising:
an electronic display comprising a front display surface and a posterior surface where no electronics are mounted directly to the posterior surface of the electronic display;
a constricted convection plate behind the posterior surface of the display; and
a fan positioned to force ambient air between the constricted convection plate and the posterior surface of the electronic display;
wherein the constricted convection plate isolates the posterior surface from electronic devices for operating said electronic display.
12. The electronic display assembly from claim 11 further comprising:
a plurality of apertures on the constricted convection plate.
13. The electronic display assembly from claim 11 further comprising:
at least one bracket which connects the posterior surface with the constricted convection plate.
14. The electronic display assembly from claim 11 further comprising:
a housing which contains the electronic display, constricted convection plate, and means for forcing air; and
an entrance aperture within the housing which permits external ambient air to enter the housing and flow between the constricted convection plate and the posterior surface.
15. The electronic display assembly from claim 11 further comprising:
a gaseous closed loop traveling across the front display surface, behind the constricted convection plate, and returning to the front display surface;
a means for propelling gas around the closed loop; and
a means for cooling the gas in the closed loop.
16. The electronic display assembly from claim 15 wherein:
the means for propelling the gas around the closed loop comprises a plurality of fans within the closed loop.
17. The electronic display assembly from claim 14 wherein:
the fan is placed near the entrance aperture.
18. The electronic display assembly from claim 11 wherein:
the electronic display comprises an LED backlight LCD display where the posterior surface is the rear surface of a backlight assembly.
