Abstract: A centrifugation device includes a feeding tube defining a longitudinal axis, and a plurality of centrifugal plates extending longitudinally and radially around the feeding tube and rotatable about the longitudinal axis. The centrifugal plates have coarse surfaces coated with one or more layers of polymer material. A centrifugation tank is disposed coaxially with the feeding tube and around the centrifugal plates. A sidewall of the tank is provided with micro/nano filters. Methods for isolation of algal biomass from an algae and aqueous mixture, and extraction of oil from kitchen residue and/or microalgae are also disclosed.

Abstract: This specification discloses a multimedia display device with dual wireless modules. It includes a body, a first wireless module, and a second wireless module. The first wireless module and the second wireless module are built in the body or connected to the body via an input/output interface. The body is connected via the first wireless module and the ISP service to the Internet. The user is enabled to access multimedia data via network hot spots or remote devices. The data are processed by a data processing control unit and presented on a display. The second wireless module is simulated by simulation software as an access point for any device with a Wi-Fi module to connect to the Internet through the first wireless module.

Abstract: This invention discloses a wireless network access multi-media apparatus having a central processing unit and a hardware driver in conformity with a connector. The connector is a wireless network connector or a cable network connector, and the host pre-stores an identity code database, so that the wireless network access multi-media apparatus can be connected to a network and a remote storage equipment through an intermediary server at the network storage end. The connection is a connection to a storage device controlled by a server or simply a connection to a storage device, so that the host can access the data in the storage device at the storage end after authentication and the host becomes a multi-media entertainment player or a work tool at a portable mobile end without requiring additional download and setup or a storage device, and thus the invention provides a quick, convenient and low-cost application.

Abstract: The present invention discloses a module and method for controlling a portable multimedia audio and video recorder/player which has an operating interface management program installed into the module for controlling audio and video recorder/player, and the operating interface management program displays certain operating function menus on a display module of the recorder/player, and builds a scrolling component into the recorder/player as a basis for executing the foregoing operating function menus, and thus the portable audio and video recorder/player can maximize its functions and operate independently under an environment without a computer system as well as simplifies the control buttons, so that users can control the recorder/player by simple operations.
