Abstract: A method for controlling power distribution unit (PDU) by an uninterruptible power supply (UPS) has steps of allowing logging in the UPS through a network, providing a web-based user interface and allowing adding an identification of at least one PDU to use sockets on the added PDU to simulate additional sockets on the UPS, performing a handshaking task with the added PDU, receiving information from the added PDU during performing of the handshaking task, displaying the received information of the added PDU on the web-based user interface and allowing either operating the UPS or controlling the added PDU. The method allows the UPS to be capable of communicating with all connected PDUs so the user can merely login the UPS to control and manage all PDUs connected to the UPS.

Abstract: A power distribution unit (PDU) performs a method using a single IP address to control multiple PDUs and has a controller and at least one network port connected to the controller. The controller provides an html-based user interface for users to set up virtual outlets therethrough. When multiple foregoing PDUs are connected through a network, one of the PDUs can be logged in with an internet protocol (IP) address, and the outlets of other PDUs are virtualized as added outlets of the login PDU. Outlet information associated with the original and added outlets of the login PDU can be simultaneously displayed on the user interface of the login PDU. Accordingly, users can employ a single IP address to control the outlets of all the PDUs.

Abstract: A method for creating virtual environmental sensor on a power distribution unit is executed by a power distribution unit and has steps of connecting to a network and at least one power-consuming device, searching all environmental sensors through the network, receiving environmental condition messages sent from each environmental sensor, presenting at least one environmental condition range to determine if the environmental condition messages sent from each environmental sensor are out of one of the at least one environmental condition range, and powering on or off a corresponding power-consuming device when each environmental condition message is out of a corresponding environmental condition range. Using the method can create remote environmental sensors networked with the PDU and solve the expansion restriction, spatial limitation and intractable wiring arising from the environmental sensor embedded in the conventional PDU in the form of hardware.

Abstract: A cavitation-like generating system includes a venturi tube, a pump for pumping water through the venturi tube, an air compressor for providing a compressed gas into the venturi tube to mix with water being pumped into the venturi tube, an accumulation tank for buffering the flow of air-water mixture coming out of the pump for output through a water outlet pipe, and a reduction valve for reducing the pressure of the output flow of air-water mixture through the water outlet pipe.
