  • Patent number: 11272222
    Abstract: A bit rate control method includes the following operations: receiving a first target bit of a video to be coded; determining a second target bit for first coding tree units (CTUs) in CTUs of the video according to the first target bit; determining a fourth target bit of at least one fourth CTU in the CTUs according to an actual bit of at least one second CTU in the CTUs and a third target bit of at least one third CTU in the CTUs, in which the at least one second CTU is completely coded, the at least one third CTU is not completely coded, and a coding of the at least one fourth CTU is not started; and sequentially adjusting at least one coding parameter for coding the video according to the second target bit, the third target bit, and the fourth target bit.

  • Patent number: 8145441
    Abstract: A portable electronic apparatus for collecting impact information includes a body, a piezoelectric element, a processing element, and a storage element. The piezoelectric element covers the body and generates an electrical signal when experiencing a force from an impact. The processing element, connected to the piezoelectric element, converts the electrical signal from the piezoelectric element into impact information. The storage element stores the impact information.

  • Publication number: 20100044861
    Abstract: A semiconductor device is disclosed including a support structure for supporting an edge of a semiconductor die that is not supported on the substrate or semiconductor die below. In embodiments, the semiconductor device may in general include a substrate having a plurality of contact pads, a first semiconductor die mounted on the substrate, and a second semiconductor die mounted on the first semiconductor die in an offset configuration so that an edge of the second semiconductor die overhangs the first semiconductor die. A support structure may be affixed to one or more of the contact pads beneath the overhanging edge to support the overhanging edge during a wire bonding process which exerts a downward force on the overhanging edge.
