  • Publication number: 20120290404
    Abstract: A system and a method for promoting multi-layer forwarding messages are provided. An embodiment of the method for use in an advertisement server system includes the following steps. At least one feedback message is received, wherein each of the at least one feedback message includes a forwarding user identifier and a user identifier of a corresponding first receiving device, and the advertisement server system interprets the at least one feedback message as a first-layer forwarding of an advertisement message associated with the forwarding user identifier. The forwarding number of the first-layer forwarding of the advertisement message is stored according to at least one feedback message of the first-layer forwarding of the advertisement message. An encouraging message is sent to a forwarding mobile device of the forwarding user identifier, wherein the encouraging message includes information based on a forwarding weight is determined according to at least the forwarding number.

  • Patent number: 8247262
    Abstract: A method for performing a CMOS Image Sensor (CIS) silicide process is provided to reduce pixel contact resistance. In one embodiment, the method comprises forming a Resist Protect Oxide (RPO) layer on the CIS, forming a Contact Etch Stop Layer (CESL), forming an Inter-Layer Dielectric (ILD) layer, performing contact lithography/etching, performing Physical Vapor Deposition (PVD) at a pixel contact hole area, annealing for silicide formation at pixel contact hole area, performing contact filling, and defining the first metal layer. The Resist Protect Oxide (RPO) layer can be formed without using a photo mask of Cell Resist Protect Oxide (CIRPO) photolithography for pixel array and/or without silicide process at pixel array. The method can include implanting N+ or P+ for pixel contact plugs at the pixel contact hole area. The contact filling can comprise depositing contact glue plugs and performing Chemical Mechanical Polishing (CMP).

  • Patent number: 8116928
    Abstract: The present invention discloses an automatic ultrasonic and computer-vision navigation device and a method using the same. In the method of the present invention, the user guides an automatic navigation device to learn and plan a navigation path; next, the automatic navigation device navigates independently and uses ultrasonic signals and computer vision to detect the environment; then, the automatic navigation device compares the detected environment data with the navigation path to amend the physical movement track. The present invention enables ordinary persons to interact with the automatic navigation device without operating the computer. As the present invention adopts computer vision and ultrasonic signals to realize the functions thereof, the manufacturers can save the hardware cost.
