  • Publication number: 20240153950
    Abstract: A semiconductor device includes a first to sixth regions, a first gate, a first metal contact and a second metal contact. The second region is disposed opposite to the first region with respect to the first gate. The first metal contact couples the first region to the second region. The fourth region is disposed opposite to the third region with respect to the first gate. The second metal contact is coupling the third region to the fourth region. The fifth region is disposed between the first gate and the second region, and is disconnected from the first metal contact and the second metal contact. The sixth region is disposed between the first gate and the first region, and is disconnected from the first metal contact and the second metal contact.

  • Publication number: 20180114336
    Abstract: A positioning method includes the steps of: capturing a positioning image by an image capturing device, determining a pixel coordinate of an object in the positioning image, and determining a global positioning system coordinate of the object according to the pixel coordinates and a transformation matrix. An image capturing device includes a camera configured to capture a positioning image, a storage medium storing with a transformation matrix, and a processor electrically connected to the camera and the storage medium respectively. The processor is configured to determine a pixel coordinate of an object in the positioning image and determine a global positioning system coordinate associated with the object according to the pixel coordinate and the transformation matrix.

  • Patent number: 5735193
    Abstract: A food processor includes a lower bowl, a mediate bowl disengagably mounted to the lower bowl, a disk mounted to the mediate bowl, a cap mounted to the disk and a shaft with a spring mounted thereto extending through the cap with a first end thereof and extending in the mediate bowl with a second end thereof so as to connect a fixing plate. The mediate bowl has a slit defined in a bottom thereof and a scrapping blade fixedly disposed to the bottom adjacent the slit. A crank member is securely connected to and rotates the other end of the shaft extending from the cap so as to rotate the shaft to scrap a large ice cube securely pressed between the bottom and the fixing plate by the scrapping blade. The shaft can alternatively rotate a blade device rotatably mounted to the lower bowl when the mediate bowl is removed.
