  • Method, a system, a transponder, and a position detection apparatus for a precise measurement of a position
    Patent number: 10495744
    Abstract: The present invention relates to a system for determining a distance, a transponder, a position detection apparatus, and a method therefor. The method for determining a distance comprises providing a position detection apparatus (101), and a transponder (105). The method further comprises generating (201) a pseudo number sequence, transmitting (202) the pseudo number sequence, receiving (203) the pseudo number sequence; modulate (204) the received pseudo number sequence by means of delaying the received pseudo number sequence a predetermined number of clock cycles from a group of at least two predetermined number of clock cycles.

  • A PHOTOGRAPHIC OBJECT DETECTION SYSTEM AND A METHOD AS WELL AS A POSITION DETECTION APPARATUS AND A TRANSPONDER, THEREFORE
    Publication number: 20170115373
    Abstract: The present invention relates to a system, a transponder, a position detection apparatus, and a method for a photographic object detection system. The method comprises providing a position detection apparatus connectable to an image capturing apparatus; and providing a transponder having an identity. The method further comprises determining a position of the transponder relative the position detection apparatus, generating transponder data comprising the identity of the transponder, and generating a signal indicative of the position of the transponder relative an image frame of the image capturing apparatus.
