Abstract: A permeable electrochemical reactive biobarrier used to prohibit the diffusion of groundwater contaminated by organic compounds is disclosed. The permeable electrochemical reactive biobarrier includes at least a conductive fiber layer and at least a cathode. The conductive fiber layer is applied with a proper voltage, and the cathode is disposed at one side of the conductive fiber layer. Herein, the conductive fiber layer can be used as the electron acceptor for respiration occurred by local soil microorganisms, which grow on the surface of the conductive fiber layer. Accordingly, the biodegradation of organic compounds can be continued without additional oxidants.

Abstract: Various systems and methods for device configuration are disclosed herein. For example, some embodiments of the present invention provide high speed pin continuity and pin-to-pin short tester circuits. Such circuits include a threshold driver, a test driver, and a comparator. An input of the threshold driver is electrically coupled to a voltage threshold, and an output of the threshold driver is electrically coupled to a test pin node via a current limiting resistor. An input of the test driver is electrically coupled to a drive data input, and an output of the test driver is electrically coupled to the test pin node. One input of the comparator is electrically coupled to the test pin node, and the other input of the comparator is electrically coupled to a threshold comparator input.

Abstract: The specification discloses a videoconference system for wireless network machines and its implementation method.
