  • Patent number: 11644872
    Abstract: A portable electronic device includes a base, a first display pivotally connected to the base, a second display, and a linkage mechanism. The first display is movable to be opened or closed relative to the base. The second display is located between the base and the first display. The linkage mechanism includes at least one first link. Two ends of the first link are pivotally connected to the first display and the second display, respectively. When the first display is opened relative to the base, the at least one first link rotates to drive the second display to move up relative to the base. When the first display is closed relative to the base, the at least one first link rotates in an opposite direction to drive the second display to move down to be accommodated between the first display and the base.

  • Publication number: 20220415081
    Abstract: An image modification method and an image modification device are disclosed. The method includes the following. A first image is obtained. A first image region in the first image and a second image region within the first image region are detected by at least one image detector. The second image region includes an image region presenting a target color in the first image region. The first image region is covered with a replacement image and a second image is generated based on an area ratio of the second image region to the first image region being greater than a predetermined value.

  • Patent number: 11353925
    Abstract: The present disclosure discloses a portable electronic device including a primary display panel, a keyboard module, a secondary display panel, and a support plate. The primary display panel includes a first pivot and a second pivot. The first pivot and the second pivot are disposed at the primary display panel. The keyboard module faces the primary display panel and includes a third pivot. One side of the secondary display panel is connected to the first pivot, and another side is a free side. The secondary display panel is flipped through the first pivot to be overlapped on an upper surface of the keyboard module or to abut against the upper surface at the free side. The support plate is flipped through the second pivot and the third pivot to be overlapped on the bottom surface of the primary display panel or to support the primary display panel.

  • Patent number: 10984787
    Abstract: A multimedia apparatus includes a wireless transmission device, an audio receiving device, a processing device and a projection device. The audio receiving device is for receiving a first voice data. The processing device is coupled with the audio receiving device and the wireless transmission device. The processing device is for outputting the first voice data via the wireless transmission device. The projection device is coupled with the processing device. When the processing device receives a first image data corresponding to the first voice data via the wireless transmission device, the processing device operates the projection device to project a first projection picture according to the first image data. A multimedia system including the multimedia apparatus is also disclosed.

  • Publication number: 20160170416
    Abstract: The flying apparatus of the invention includes a main body, a first distance sensor and a second distance sensor. The first distance sensor and the second distance sensor are disposed at the bottom surface and the top surface of the main body, respectively. Moreover, the main body has a processing module that can receive the sensed signal outputted from the first distance sensor or the second distance sensor and output a displacement signal according to the content of the first sensed signal. When the relative distance between the first distance sensor and the sensed object is shorter than a default reception distance, the first distance sensor outputs the first sensed signal. When the relative distance between the second distance sensor and the sensed object is shorter than the default reception distance, the second distance sensor outputs the first sensed signal.
