20120162095 | INTERNAL OPTICAL COATING FOR ELECTRONIC DEVICE DISPLAY - An internal optical coating includes multiple layers of different materials and thicknesses and is disposed between a transparent display cover and a visual display unit for an electronic device display. The optical coating transmits most visible light, reflects most non-visible light and substantially absorbs blackbody radiation generated from within the electronic device. The multiple layers comprise two or more materials having alternating low and high indices of refraction, and can include 36 or more layers, each having a thickness ranging from 10 to 400 nanometers. The arrangement and thicknesses of the layers are designed based upon the thickness and optical properties of the transparent display cover. The internal optical coating can also be specially formulated to replace a typical internal anti-reflective coating proximate the visual display unit. | 06-28-2012 |
20120162751 | OPTICAL COATING FOR ELECTRONIC DEVICE DISPLAY - An optical coating includes multiple layers of different materials and thicknesses and is disposed proximate a transparent display cover for an electronic device display. The optical coating transmits most visible light, reflects most non-visible light and substantially absorbs blackbody radiation generated from within the electronic device. The optical coating can be readily removable from the electronic device display either alone or in combination with a removable transparent display cover. The multiple layers comprise two or more materials having alternating low and high indices of refraction, and can include 36 or more layers, each having a thickness ranging from 10 to 400 nanometers. The arrangement and thicknesses of the layers are designed based upon the thickness and optical properties of the transparent display cover. | 06-28-2012 |
20120224951 | COMPACT FAN ASSEMBLY WITH THRUST BEARING - A fan assembly for a computing device is disclosed. The device can include an impeller having a number of blades and a motor for turning the blades. The motor can turn the blades via a magnetic interaction between the impeller and the motor. A thrust bearing can be used to control a position of the impeller relative to the motor. In particular, the impeller can be configured to rotate around an axis and the thrust bearing can be used to control movement of the impeller in a direction aligned with the axis. In one embodiment, the impeller can be configured to generate aerodynamic forces, such as lift, and the parameters associated with the thrust bearing can be selected to counteract the aerodynamic forces so that the impeller remains within a desired positional range relative to the motor. | 09-06-2012 |
20130319638 | THERMAL ARCHITECTURE - The described embodiment relates generally to the field of thermal management. More specifically an apparatus for cooling a unibody computing device with obscured inlet and outlet vents is disclosed. Inlet vents are arranged on a bottom surface of the unibody computing device and then exhaust air is vented out from a rear surface of the computing device. The rear vents can be obscured by a stand designed to support the weight of the computing device. By venting exhaust air to either side of the support stand exhaust air can be prevented from being drawn back into the inlet vents, thereby avoiding an overheating condition. | 12-05-2013 |
20130327507 | OPTIMIZED VENT WALLS IN ELECTRONIC DEVICES - The disclosed embodiments related to a component for use in a portable electronic device. The component includes a wall of the portable electronic device, containing an intake zone that includes a set of intake vents directed at a first angle toward one or more heat-generating components of the portable electronic device. The wall also includes an exhaust zone containing a set of exhaust vents directed at a second angle out of the portable electronic device. | 12-12-2013 |
20130329357 | GASKETS FOR THERMAL DUCTING AROUND HEAT PIPES - The disclosed embodiments provide a component for a portable electronic device. The component includes a gasket containing a rigid portion disposed around a bottom of a heat pipe, wherein the rigid portion forms a duct between a fan and an exhaust vent of the electronic device. The gasket also includes a first flexible portion bonded to the rigid portion, wherein the first flexible portion comprises a flap that is open during assembly of the heat pipe in the electronic device and closed over the heat pipe and the rigid portion to seal the duct around the heat pipe after the assembly. | 12-12-2013 |
