  • Publication number: 20100143082
    Abstract: A system comprising a conveyor. A semiconductor processing tool has a lifter port. The tool is positioned near the conveyor, such that the lifter port is configured to transport a Front Opening Unified Pod (FOUP) between the conveyor and the lifter port. An upstream stocker and a downstream stocker are both co-located with the conveyor and the tool. The upstream and downstream stockers each have a respective storage space for the FOUP and a respective robotic device configured to transport the FOUP between its respective storage space and the conveyor. The upstream stocker is configured to receive the FOUP from an overhead transport (OHT) and deliver the FOUP to the conveyor. The downstream stocker is configured to receive the FOUP from the conveyor and deliver the FOUP to the OHT.

  • Patent number: 7076293
    Abstract: A computer-aided automatic vital acupuncture point alignment and electronic acupuncture method uses a system comprised of a computer, a digital imaging device, a digital probe device and an electronic acupuncture device. The computer takes a picture of a patient's body with the digital imaging device and automatically marks vital acupuncture points on the picture from a standard body's picture on which all vital acupuncture points are marked and localizes the vital acupuncture points on the patient's skin with the digital probe device. A practitioner uses the electronic acupuncture device to touch the vital acupuncture points on the patient's skin based on the patient's picture. The computer outputs a suitable wave signal through the electronic acupuncture device to the skin. Therefore, the present invention identifies the vital acupuncture points on the skin to have a good curative effect.
