20140026653 | Radiation-Blocking Structures - Stacked layers of non-continuous opaque layer structures are disclosed herein that may be configured to block radiation such as visible light or other forms of light, while at the same time allowing penetration of ambient gases. In one example, such non-continuous opaque layer structures may be configured as stacked non-continuous metal layer structures that together fully block penetration of radiation while at the same provide sufficient open spaces between and/or within the metal layer segments of a given integrated circuit layer to meet maximum metal spacing rules. In another example, such non-continuous opaque layer structures may be configured as capacitive structures. | 01-30-2014 |

20130212386 | Storage Access Authentication Mechanism - In embodiments according to the present invention an encryption switch is used to authorize access to LUNs from client VMs present in the cloud provider network. The encryption switch includes responder side software for an authentication protocol and an agent in the client VM includes the requestor side of the authentication protocol. The certificate of the client is securely provided to the encryption switch, which associates the client VM with the LUN. The client private key is securely provided to the client VM, which retains it only non-persistently. The client VM requests LUN access and performs an authentication handshake with the encryption switch. If successful the client VM than has access to the LUN. As the original certificate is linked to the client, if the client is itself a VM, should the client be moved to a different host, the certificate moves with it and LUN accessibility is maintained. | 08-15-2013 |
20130219169 | Public Cloud Data at Rest Security - An encryption switch which is used in a cloud environment to secure data on the LUNs used by the clients. A client provides a certificate to the cloud service. The encryption switch develops a cloud crypto domain (CCD) as a secure area, with the data at rest on the LUNs encrypted. The encryption switch develops a master key for client use in the CCD, which is provided to the client encrypted by the client's public key. Data encryption keys (DEKs) are created for each LUN and provided to the client. The DEKs are stored in a key vault by the client for use if needed. The cloud service provisions a client VM to be used with the encrypted LUN and develops a nexus between the LUN and the client VM for the encryption switch to use in data operations. The client communicates through the client VM to access the LUN. | 08-22-2013 |

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 |
