  • Publication number: 20150058500
    Abstract: A communication apparatus includes a host, a signal receiving apparatus arranged to receive a wireless signal, and a connecting device coupled between the host and the signal receiving apparatus. The connecting device is arranged to transmit a transmission signal between the host and the signal receiving apparatus. The signal receiving apparatus refers to the state of the received wireless signal to control the connecting device to selectively enter a second operation mode from a first operation mode to reduce the interference upon the wireless signal.

  • Patent number: 8725208
    Abstract: A serial transmission interface between an image sensor and a baseband circuit includes a transmission end and a reception end. The transmission end is set in the image sensor, and is utilized for transmitting image data sensed by the image sensor. The reception end is set in the baseband circuit, and is utilized for receiving the image data transmitted from the transmission end. The transmission end is one of a master control end and a slave control end, and the reception end is correspondingly the other.

  • Publication number: 20050207636
    Abstract: An automatic-packaging apparatus which can package an optical sensing module with a preferred distance between a lens and an optical sensor includes a base, an image-analyzing module, a distance-adjusting module, and a stain-detecting module. The automatic-packaging apparatus packages a lens and an optical sensor separated in a preferred distance into an optical sensing module, and is able to detect if there are stains on the lens or there are flaws in the optical sensor. The advantages of the automatic-packaging apparatus are to package and detect optical modules quickly, efficiently and accurately.
