Abstract: The electrochemical method of producing hydrogen peroxide using a titanium oxide nanotube catalyst is an electrochemical process for producing hydrogen peroxide using a cathode formed as a nanostructured titania (TiO2) electrode surface treated with nitrogen. An anode and the cathode are immersed in an alkaline solution saturated with oxygen in an electrolytic cell. An electrical potential is established across the cathode and the anode to initiate electrochemical reduction of the oxygen in the alkaline solution to produce hydrogen peroxide dissolved in the alkaline solution. The hydrogen peroxide dissolved in the alkaline solution is then collected from the cell.

Abstract: Disclosed are network managed volumes that enable simplified and more efficient use of information technology assets by allocating physical disk drives as needed. A pool of storage can be defined and populated with physical disks that are accessible in a storage area network. Virtual volumes are created from the storage pool, with each virtual volume being separately allocable to a host device (e.g., client, application server, etc.). Thus, host devices that have been allocated these virtual volumes perceive ownership of the entire volume, without requiring a present allocation of physical storage space having the same characteristics, but with seamless introduction of physical resources as needed.

Abstract: An apparatus and method for testing an independent monitoring circuit in an LED traffic signal is provided. The apparatus comprises: a proof test circuit embedded within the traffic signal; and a proof test device embedded within the traffic signal. The method comprises: via the proof test circuit, simulating a faulty traffic signal state; activating the independent monitoring circuit without switching the traffic signal into a high impedance state; energizing the proof test device; and via the proof test device, communicating externally the current state of the independent monitoring circuit.

Abstract: A signal is described herein that provides light output for automotive, rail, ship traffic and/or illumination control that includes a light emitting diode (LED) array, wherein the LED array includes three groups of disparate colored LEDs. A power supply unit provides independent power to each of the three LED groups. Each LED group power supply unit includes an input controlled switch connected to a power line to provide power to the LED array. An input under voltage/over voltage circuit monitors the voltage level of the power line and for enabling and/or disables the input controlled switch according to the voltage level of the power line. A flyback transformer converts the power received from the power line from an alternating or a continuous current signal to a direct current signal output to the LED array.
