Abstract: This invention concerns an ergonomic optical see-through head mounted display device with an eyeglass appearance. The see-through head-mounted display device consists of a transparent, freeform waveguide prism for viewing a displayed virtual image, a see-through compensation lens for enabling proper viewing of a real-world scene when combined together with the prism, and a miniature image display unit for supplying display content. The freeform waveguide prism, containing multiple freeform refractive, and reflective surfaces, guides light originated from the miniature display unit toward a user's pupil and enables a user to view a magnified image of the displayed content. A see-through compensation lens, containing multiple freeform refractive surfaces, enables proper viewing of the surrounding environment, through the combined waveguide and lens.

Abstract: Optical systems such as image display systems include a freeform optical waveguide prism and a freeform compensation lens spaced therefrom by a gap of air or index cement. The compensation lens corrects for aberrations which the optical waveguide prism will introduce in light or images from an ambient real-world environment. The optical waveguide prism receives actively projected images at an entry location, and emits the projected images at an exit location after internally reflecting the images along an optical path therein. The image display system may include an image source and coupling optics. The approach permits design of an optical viewing device, for example in optical see-through HMDs, achieving an eyeglass-form appearance and a wide see-through field of view (FOV).

Abstract: A power supply control method and a wireless terminal. The method includes, in a part or all of a time period during which a wireless terminal is in a dormant state, stopping supplying power to some or all circuits of a radio frequency circuit in the wireless terminal, where the dormant state includes at least one of a dormant state in a discontinuous transmission (DTX) period and a dormant state in a discontinuous reception (DRX) period and the problems of electric energy waste and service life reduction of a wireless terminal are resolved.

Abstract: An optical system for eye tracking is disclosed. The system includes a light guiding prism that guides light from an ocular object to an imaging system through multiple internal reflections. The light guiding prism may include one or more freeform surfaces having optical power.

Abstract: Embodiments of the present invention disclose a method for manufacturing a circuit board, and a circuit board. The method includes: separately fixing at least two function modules and a shielding frame on a circuit board, where the shielding frame is located between the at least two function modules; packaging the at least two function modules and the shielding frame by using a plastic package material; cutting the plastic package material corresponding to the top of the shielding frame to a surface of the shielding frame; and covering an outside of the plastic package material and an top part of the shielding frame with a conducting material, and covering a surface of the conducting material with an insulation material. In the embodiments, the cutting height is decreased, the processing time is short, and good manufacturability is provided.

Abstract: The method of the present invention includes: obtaining an original signal outputted by a SIM card; converting the original signal into a target signal, where under an equal transmission condition and/or at an equal transmission distance, signal attenuation and/or distortion of the target signal are/is less than signal attenuation and/or distortion of the original signal; and sending the target signal to a terminal device, where the terminal device obtains the target signal by using a signal transmission line, and the SIM card exists independent of the terminal device. In the present invention, a SIM card may be separated from a terminal device, and a generated target signal may be transmitted over a relatively long distance by using a signal transmission line, which can satisfy an application that requires a SIM card to be placed far away from a terminal device.
