Abstract: An example device includes a first liquid container with a bladder and a number of flaps and a second liquid container with a bladder and a number of flaps, and one of the flaps of the second liquid container is affixed to one of the flaps of the first liquid container.

Abstract: Key-value data is processed. An example method includes acquiring key-value data, including key data and value data, and a storage level corresponding to the key-value data and indicating a storage performance level of a memory in a storage system. In response to the storage level being a first level higher than a second level, the key-value data is stored in a primary storage tree in a first memory. In response to the storage level being the second level, the key data is stored in the primary storage tree, and the key-value data is stored in a secondary storage tree in a second memory. Beneficially, associations can be established between different memories in the storage system through the key data using fast positioning of all the key-value data implemented through memories with high storage performance. Further, the efficiency of data processing in the storage system is thereby improved.

Abstract: A system and method for channel estimation in a wireless local area network. A corresponding channel estimation method includes the steps of: receiving a preamble message and despreading the preamble message into several symbol signals, each symbol signal containing several discrete signals; determining for each symbol signal a peak sign assignment; establishing several data windows for the symbol signals at the starting points of the discrete signals; multiplying the discrete value of each discrete signal of each data window by the corresponding peak sign assignment and accumulating the product in the first data frame; repeating the above steps for the next discrete signal and accumulating them in the second data frame, . . . , the Nth data frame; computing the accumulated value in the data frames and obtaining the data frame with the maximum value; estimating a channel signal from the previously determined data frame.
