  • Patent number: 5181109
    Abstract: The present invention provides a circuit of eliminating motional vector remaining caused by transmission error, comprising : an input terminal for inputting an interframe motional vector; first delay device 42 connected to the input terminal, for delaying the interframe motional vector as much as a predetermined time; a zero detector 43 connected to the input terminal and to the first delay device 42, for detecting that both the delayed interframe motional vector and the interframe motional vector are continuously in zero state more than a predetermined number; and a switch 47 connected to the zero detector, for forcibly outputting zero("0") just in case that the zero detector detects zero more than the predetermined number.

  • Patent number: 5075400
    Abstract: The invention discloses the processes and materials for treating materials to minimize the deposition of proteins and other molecules, and for removing proteins and other molecules from materials. New copolymers containing polyethylene oxide sidechains called supersurfactants have the ability to bind themselves to interfaces to provide a stable protein-resistant interface. A process is presented to treat and modify interfaces with the new copolymers.
