  • Patent number: 10194397
    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.

  • Publication number: 20190018247
    Abstract: Several unique hardware configurations and methods for freeform optical display systems are disclosed. A freeform display system includes primary freeform optical element(s) and secondary freeform optical element(s) in tiled arrangements to expand the horizontal field of view (FOV) or the vertical field of view. The system may include a variable focusing system that produces intermediate pupil and changes the focal distance of a single focal plane or switches among multiple focal planes for rendering objects in focus while resolving accommodation-convergence conflict. The system may map light samples to appropriate light rays in physical space and use a cluster of projectors to project the mapped light rays to produce the light field of the virtual display content. Methods for making tiled freeform optical display systems and methods for producing virtual content with variable focus freeform optics and rendering light fields are also disclosed.

  • Patent number: 10142831
    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.

  • Publication number: 20180275409
    Abstract: Examples of eye-imaging apparatus using diffractive optical elements are provided. For example, an optical device comprises a substrate having a proximal surface and a distal surface, a first coupling optical element disposed on one of the proximal and distal surfaces of the substrate, and a second coupling optical element disposed on one of the proximal and distal surfaces of the substrate and offset from the first coupling optical element. The first coupling optical element can be configured to deflect light at an angle to totally internally reflect (TIR) the light between the proximal and distal surfaces and toward the second coupling optical element, and the second coupling optical element can be configured to deflect at an angle out of the substrate. The eye-imaging apparatus can be used in a head-mounted display such as an augmented or virtual reality display.
