    Abstract: A method for packaging the sensor units is shown below. First step is providing a substrate, and each sensor area on the substrate is partitioned into two individual circuit areas. An emitter and a detector are installed on the two circuit areas respectively. Step two is forming a first packaging structure to cover the two circuit areas, the emitter and the detector by a mold. Next step is cutting the first packaging structure to form cut groove between and around the emitter and the detector. Next step is forming a second packaging structure in the cut grooves by the same mold. At last, the panel of sensor units is diced and separated as individual sensor units. As above-mentioned, the second packaging structure is used for isolating the signals of the emitter and the detector.

  • Patent number: 8150434
    Abstract: A leadership support system includes a leader terminal and plural member terminals. The member terminals, according to either the relay of communication information not addressed thereto or the reception of communication information addressed thereto, send back a response to the appropriate communication information. The leader terminal determines, based on the times of relaying the communication information, whether or not the member terminal that transmitted the communication information is in danger of isolation. When the leader terminal determines the member terminal in danger of isolation, it outputs a warning signal indicative of a ranger of isolation to that member terminal.
