Abstract:
A formable structure comprises a first material having a first level of viscosity and a second material having a second level of viscosity, wherein the second material is formed to hold at least a portion of the first material in a particular position or a particular shape. The first material can be configured to function as a thermal interface between two or more hardware components. The second material can be configured to have a higher viscosity than the first material. In one illustrative example, the second material can include a light-activated resin that is configured to harden when exposed to one or more treatments. By the use of the first material and second material, the techniques disclosed herein are adaptable to gaps having a wide range of sizes, which is difficult to do with traditional thermal interface materials. The second material can also function as an EMI shield.
Abstract:
A thermal conduit configured to conduct heat from a heat source to a heat sink and method of forming said conduit are disclosed herein. The thermal conduit may comprise a plurality of stacked sheets formed of an anisotropically thermally conductive material, a non-limiting example of which is graphite, each sheet with a respective orientation of thermal conduction. The orientations of thermal conduction of the plurality of sheets may change stepwise in a stacking direction to form a curved thermal flow path.

The substrates are joined by an adhesive configured to have suspended therein a plurality of hard microspheres. The adhesive may be a pressure sensitive adhesive designed to have suspended therein the microspheres. Microspheres may have diameters on the order of a few microns up to 100 microns. The waveguide may be constructed of first and second optical substrates, and a pressure sensitive adhesive including embedded microspheres joining and spacing the substrates apart from each other. Additional substrates may be provided. The technology also provides a method of manufacturing a waveguide.
Abstract:
A head-up display system comprises a microprojector, first and second viewer optics, a redirection optic, and an electronic controller. Switchable electronically between first and second optical states, the redirection optic is configured to receive a display image from the microprojector, to convey the display image, in the first optical state, to the first viewer optic, and to convey the display image, in the second optical state, to the second viewer optic. The electronic controller is configured to, during a first interval, switch and maintain the redirection optic in the first optical state and cause the microprojector to form the display image based on first image data. The electronic controller is further configured to, during a second interval, switch and maintain the redirection optic in the second optical state and cause the microprojector to form the display image based on second image data.
Abstract:
A passive thermal heat-pipe material comprising an optical mounting structure including heat producing electronic components is provided. Each structural component of the optical mounting structure may be at least partially comprised of a polymer including a plurality of carbon nanoparticles. In a further aspect, a method of creating an optical structure adapted to support a plurality of heat emitting components is provided. The method includes adding a percentage by concentration of carbon nanoparticles to a polymer base material, mixing the polymer base material and carbon nanoparticles uniformly, melting the mixture at high temperature, forming the melted mixture into a component of the optical structure, and cooling the formed component to solidify the component. The percentage may be between 2 and 10 percent.
Abstract:
This is directed to methods and apparatus for shielding a circuitry region of an electronic device from interference (e.g., EMI). A conductive dam may be formed about a periphery of the circuitry region. A non-conductive or electrically insulating fill may then be applied to the circuitry region within the dam. Next, a conductive cover may be applied above the fill. The cover may be electrically coupled to the dam. The dam may include two or more layers of conductive material stacked on top of one another. In some embodiments, the conductive cover may be pad printed or screen printed above the fill. In other embodiments, the conductive cover may be a conductive tablet that is melted above the fill.

Abstract:
The techniques disclosed herein provide an enhanced mount for a camera module. The mount comprises at least a first side and a second side. The sides are formed to enable contact with at least a portion of the camera module. The sides are configured with openings to enable a fastening material, such as an adhesive, to secure the camera module to the mount. Openings within the mount enable the use of a fastening material to secure the camera module to at least one surface of the mount while allowing the camera module and at least one surface to maintain the mechanical contact. In some configurations, one or more openings are formed such that a contraction of the fastening material pulls the camera module toward at least one surface of the mount.
