20140380040 | SECURE BIOMETRIC CLOUD STORAGE SYSTEM - A secure and scalable data storage system that includes a server and a plurality of clients. The server maintains an access permission file that includes a file-group name, a plurality of client access blocks, a first and second public key, and a signature that is based on a first private key. The signature ensures that only clients who have a certain level of access can modify the contents of the access blocks. Each client access block includes at least one of a first access key, a second access key and a third access key. The access keys are encapsulated within biometric information of the client. The server grants one of a first level of access based on a successful verification of a signed request with the first public key and a second level of access based on a successful verification of the signed request with the second public key. | 12-25-2014 |

20080314064 | AIR CONDITIONING SYSTEM - An air conditioning and heating system includes an condenser, an expansion valve, an evaporator and a compressor interconnected in a closed loop system, and a motor for driving the compressor. The system also includes a refrigerant disposed within the closed loop system. The compressor compresses the refrigerant and pumps the refrigerant through the system. The system also includes one or more feedback loops to reduce the temperature (pre-cool) the refrigerant before it reaches the expansion valve in the cooling mode and the same or a different heat exchanger in the heating mode. The additional heat exchangers are placed in the loop to reduce the electric energy being used. | 12-25-2008 |

20150148581 | METHODS FOR PREPARING COMPOSITES OF ACTIVATED CARBON/ZINC OXIDE AND ACTIVATED CARBON/ZINC OXIDE/NICKEL OXIDE FOR DESULFURIZATION OF FUELS - Activated carbon\nickel oxide\zinc oxide (AC\NiO\ZnO) and activated carbon\zinc oxide (AC\ZnO) were prepared and used as adsorbents for removal of thiophene, benzothiophene (BT) and dibenzothiophene (DBT) as sulfur compounds from hydrocarbon materials such as diesel fuel. The materials exhibited an efficient and economical way for removing sulfur compounds due to its low-energy consumption, ambient operation temperature and atmospheric pressure. A simple regeneration method of the spent adsorbents. | 05-28-2015 |

20130091913 | METHOD OF MAKING AN ACID-ABSORBING BIOSOLID COMPOSITION - The method of making an acid-absorbing biosolid composition provides a method for the use of recycled materials to produce an acid-absorbing composition that may then be recycled as a fertilizer after absorbing the acid. The method includes the steps of: collecting sewage sludge; drying the sewage sludge to remove water therefrom to form dried sludge; adding hydrochloric acid to the dried sludge to form a liquid intermediary product; heating the liquid intermediary product to produce a dried porous biomass; and mixing inorganic waste material with the dried porous biomass to produce the acid-absorbing biosolid composition. Thereafter, the acid-absorbing biosolid composition may be placed in a gas flow to absorb an acidic component therefrom; and then recycled for use as fertilizer following absorption of the acidic component from the gas flow. | 04-18-2013 |

20130226904 | DETERMINING DISTANCE BETWEEN DATA SEQUENCES - A lowest common ancestor of a first data sequence and a second data sequence is determined. Based on the lowest common ancestor, symbols that differ between the first data sequence and the second data sequence are identified. A distance between the first data sequence and the second data sequence is determined based on the symbols. | 08-29-2013 |
