  • Patent number: 9436189
    Abstract: An apparatus for regulating temperature is presented. The apparatus comprises: a shell comprising a first cavity and a second cavity; and an inner valve body and an outer valve body disposed in the shell between the first cavity and the second cavity, wherein the inner valve body is movable relative to the outer valve body, and the outer valve body is movable within the shell. Depending on the temperature inside the shell, the inner valve body and the outer valve body can substantially seal the first cavity from the second cavity. The inner valve body and the outer valve body can also provide, respectively, a first flow path and a second flow path between the cavities, depending on the temperature.

  • Patent number: 6208692
    Abstract: An apparatus and a concomitant method for performing hierarchial block-based motion estimation with a high degree of scalability is disclosed. The present invention decomposes each of the image frames within an image sequence into an M-ary pyramid. Different dynamic ranges for representing the pixel values are used for different levels of the M-ary pyramid, thereby generating a plurality of different “P-bit” levels, i.e., a plurality of different M-ary pyramid architectures. The present scalable hierarchical motion estimation provides the flexibility of switching from one M-ary pyramid architecture to another M-ary pyramid architecture according to the available platform resources and/or user's choice.
