Abstract: A display may include illumination optics (36), a spatial modulator (40) and a waveguide (26). The illumination optics may produce illumination that is modulated by the spatial modulator to produce image light. The waveguide may direct the image light towards an eye box. The illumination optics may include light sources (58) an X-plate (44), and at least one Fresnel lens (60) interposed between the light sources and the X-plate. The Fresnel lenses may minimize the size of the illumination optics while still exhibiting satisfactory optical performance. The spatial light modulator may include a reflective display panel (50) and a powered prism (48) with a reflective coating on a curved reflective surface. The powered prism may optimize f-number while minimizing the volume of the spatial light modulator. The collimating optics may include a diffractive optical element (56) that compensates for thermal effects and chromatic dispersion in the display.

Abstract: An interactive music on-demand method, device, and terminal are provided. The method includes: acquiring on-demand requirement information; determining that the on-demand requirement information meets an inquiry requirement condition; and generating an on-demand inquiry voice according to the on-demand requirement information and an on-demand option set corresponding to the on-demand requirement information, in response to the on-demand requirement information meeting the inquiry requirement condition; acquiring on-demand selection information in response to the on-demand inquiry voice; and playing music according to the on-demand selection information.

Abstract: A method and an apparatus for processing a voice request are provided. The method includes: searching, in response to determining that a target multimedia resource requested to be played in a voice request is not included in a preset multimedia resource library, for the target multimedia resource in a resource library other than the multimedia resource library; and sending a link address of the found target multimedia resource ant an instruction for playing the target multimedia resource to a smart voice device. The coverage of the content of a voice service is expanded, thereby improving the efficiency of the voice service.

Abstract: The invention is a method to salvage suspensions from defective head gimbal assembly units. At present the hard disk industry is undergoing rapid product cycles. The products are being upgraded faster and faster, and the ability for sliders to meet higher density requirement becomes more urgent. Therefore, the performance of a slider becomes more sensitive to signals. As the wafer manufacturing process produces a lower yield, a suspension salvage method is developed to recycle a damaged head gimbal assembly in order to minimize material loss.

Abstract: A method to salvage suspensions from defective head gimbal assembly units is presented. Because the performance of a slider becomes more sensitive to signals and the wafer manufacturing process produces a lower yield, a suspension salvage method is developed to recycle a damaged head gimbal assembly in order to minimize material loss. In one embodiment, the salvage method includes separating a gold ball from a bonding pad of the suspension, twisting off the slider attached to the suspension, and dissolving the remaining epoxy.
