| 20090230012 | VACUUM ACTIVATED SHIPPING CONTAINER - A shipping container having side walls, a bottom and a top defining an internal volume. The top is selectively displaceable for gaining access to the internal volume and for sealing the internal volume of the container. A valve drawing a vacuum on the internal volume from outside of the container is provided. The side walls are capable of contracting and expanding as a result of the pressure within the internal volume. | 09-17-2009 |

| 20100149005 | VARIABLE LENGTH DECODING APPARATUS AND METHOD - Techniques, apparatus and systems are described for performing variable length decoding. In one aspect, a variable length decoding apparatus includes a first computation unit to determine whether a symbol corresponding to an input data is included in an upper group or a lower group of a variable length code tree. Responsive to the determination, when the symbol corresponding to the input data is included in the lower group, the first computation unit detects look-up table information corresponding to a subgroup that includes the symbol corresponding to the input data within the lower group that includes multiple subgroups. The variable length decoding apparatus includes a second computation unit to detect the symbol corresponding to the input data by searching a look-up table corresponding to the look-up table information when the look-up table information is received from the first computation unit. | 06-17-2010 |

| 20100088687 | Variable Length Code Table Clustering Method, and Method and Apparatus for Sharing Memory of Multi-Codec by Using the Variable Length Code Table Clustering Method - Provided are a method and apparatus for sharing a memory of a multi-codec. For each of a plurality of codecs, the method and apparatus cluster a variable length code tree into a plurality of groups whereby a level difference between symbols in each group of the plurality of groups is less than a predetermined value, wherein the variable length code tree corresponds to at least one of variable length code tables for each of the plurality of codecs, refer to maximum levels of the symbols in each group of the plurality of groups, and determine a storage capacity of an internal memory shared between the variable length code tables for the plurality of codecs. | 04-08-2010 |
