Abstract: A composite shoe sole having an outsole which is made of rubber, plastic or thermoplastic rubber (TPR), and a plurality of small pieces of fabrics filled inside the outsole; the outsole and the plurality of small pieces of fabrics are injection-molded and integrally formed. A method of making the composite shoe sole is also disclosed. The composite shoe sole allows the shoe sole to have good flex resistance when flexed thanks to the small pieces of fabrics filled inside the outsole. The small pieces of fabrics also provide good puncture resistance to the shoe sole, thus increasing the usage life of the shoe sole. Also, the shoe sole is lighter and cost is reduced. When transparent material is used for making the outsole, the small pieces of fabrics inside the outsole can render the whole shoe sole a visual effect different from conventional shoe soles.

Abstract: Power consumption related data for the power source supplying an entire household or other group of appliances is captured at a relatively high data rate. The raw data is analyzed to remove redundancy and to identify pertinent features, and then the more informative of these features are then selected. The analysis and selection of features are pre-processing tasks that are performed on-site, on the same piece of hardware that acquires the raw data and transmits the pre-processed data to the server. By transmitting selective data to a remote server, only a low bandwidth is required for the transmission.
