  • Publication number: 20190250281
    Abstract: A satellite signal receiving circuit includes an oscillator, two mixers, two phase shifters, two low-pass filters, two phase operation circuits, and a bandpass filter. When the frequency of the oscillator is between the center frequencies of the Global Orbiting Navigation Satellite System (GLONASS) and the GPS or the Galileo system, the GLONASS and GPS/Galileo satellite baseband signals are obtained through phase addition and subtraction performed by the phase operation circuits, while the BeiDou Navigation Satellite System (BDS) baseband signal is obtained through the bandpass filter. When the frequency of the oscillator is between the center frequencies of the BDS and the GPS or the Galileo system, the BDS and GPS/Galileo satellite baseband signals are obtained through phase addition and subtraction performed by the phase operation circuits, while the GLONASS satellite baseband signal is obtained through the bandpass filter.

  • Patent number: 10331008
    Abstract: A device for controllably deflecting a first circularly-polarized (CP) light beam from an incident direction with fast response comprises a polarization selector (PS) to adjust the incident light beam's sense of rotation to a desired one to form a second CP light beam, and a polarization grating (PG) to deflect the second CP light beam according to the desired sense of rotation. The PS comprises an optical modulator sandwiched between two quarter-wave plates. The optical modulator has at least one ferroelectric liquid crystal (FLC) half-wave plate (HWP) being reconfigurable in fast axis orientation. The device has a fast response in beam steering due to a short time of reconfiguring the FLC HWP. Based on serially cascading multiple units each being this device, a beam-steering apparatus having fast response and enhanced steering resolution is obtained. The apparatus is usable for enhancing a field of view in projecting an image.

  • Patent number: 10247221
    Abstract: A housing of an active component, which is used to install an active source, includes a main portion and at least two fixing portions. The main portion has side walls. The active source is installed on the main portion. The Young's modulus of the material making the fixing portion is different from the Young's modulus of the material making the main portion. The fixing portion is formed with fixing holes, and is connected to the side wall of the main portion. It therefore provides better effects of shock proofing and shock isolation without unnecessary noise, and prevents a fixing element fixing the active component from being loosened, with enhanced stability of the active component. The present invention also provides a manufacturing method for housing of the active component.
