| 20090243570 | 5 VOLT TOLERANT VOLTAGE REGULATOR - A voltage regulator circuit comprises an error amplifier for generating an error signal responsive to a reference voltage in a feedback signal. A feedback circuit provides the feedback voltage signal to the error amplifier and a driver circuit provides regulated output voltage responsive to the input voltage in the error signal. Short circuit protection circuitry selectively protects transistors within the error amplifier, the feedback amplifier and the driver circuit responsive to a short circuit protection enablement signal. | 10-01-2009 |
| 20090248930 | USB TRANSCEIVER CIRCUITRY INCLUDING 5 VOLT TOLERANCE PROTECTION - An integrated circuit includes USB communication circuitry for communicating via a USB interface. The USB transceiver circuitry transmits data to and from the integrated circuit over the USB interface. The USB transceiver circuitry further provides protection to internal circuitry of the integrated circuit from a 5 volt short circuit on the USB interface. | 10-01-2009 |

| 20120044933 | METHOD AND APPARATUS FOR ROUTING BETWEEN FIBRE CHANNEL FABRICS - An interfabric link between two separate Fibre Channel fabrics so that devices in one fabric can communicate with devices in another fabric without requiring the merger of the two fabrics. The interfabric switch performs a conversion or a translation of device addresses in each fabric so that they are accessible to the other fabric. In a first embodiment the external ports of the interfabric switch are configured as E_ports. A series of internal ports in each interfabric switch are joined together forming a series of virtual or logical switches. In a second embodiment the external ports are configured as NL_ports and the connections between the virtual switches are E_ports. The virtual switches in the interfabric switch match domains with their external counterparts so that the virtual switches effectively form their own fabric. | 02-23-2012 |

| 20080210552 | SMALL PORTABLE ELECTROLYTIC SODIUM HYPOCHLORITE ON SITE GENERATORS - The present invention describes four preferred embodiments of an apparatus aimed to the production of a dilute solution of sodium hypochlorite. It uses the process of the electrolysis of a dilute solution of sodium chloride in water by means of two metallic electrodes immersed in the solution. The electricity needed may be delivered by a range of sources like disposable cells (alkaline), rechargeable batteries, photovoltaic modules (PVM) or electromechanical generators, like alternators or dynamos, moved by human power. All the apparatus described operate in batch mode. They are small lightweight portable units, easily transportable anywhere, in remote areas or emergency situations where chemicals or electricity is not available. Main use is the purification of drinking water, but also the production of sterilizing solutions for wound disinfection, washing etc. | 09-04-2008 |
| 20090008267 | PROCESS AND METHOD FOR THE REMOVAL OF ARSENIC FROM WATER - This invention describes a one step process for the removal of heavy metals, particularly arsenic, from water. The process consists in promoting the circulation of the water to be treated in an electrolytic cell equipped with iron, or iron alloy anodes and cathodes made of iron or iron alloy or other metals, while the contemporary insufflation into the cell of a gas, partially or totally composed of oxygen. In this way the iron of the anode electrodes dissolves as iron hydroxide. The ferrous hydroxide thus generated, under the action of the oxygen contained in the insufflated gas is converted to ferric hydroxide, which, through a complex mechanism, adsorbs and forms insoluble complexes with the arsenic ions. At the same time As(III) is subject to oxidation both at the anode and at the cathode. By this process both forms of arsenic, As(III) and As(V), are equally removed. The treated water is further processed by conventional clarifying and filtering. | 01-08-2009 |

| 20090093263 | Conservation of paging resources in a mobile switching center - A method in one example comprises the steps of receiving a call intended for a designated cellular subscriber unit at a serving MSC, determining that the designated cellular subscriber unit, during a recent prior use of the serving MSC, responded to an Intersystem Page (ISPAGE) message from a border MSC, and transmitting an initial paging message to the designated cellular subscriber unit via an ISPAGE message directed toward said border MSC. | 04-09-2009 |
| 20100120451 | Method for paging a mobile unit based on previous network interactions - To address the need for new techniques that can improve paging efficiency, a network may employ a method such as that depicted in flow diagram | 05-13-2010 |
