| 20090156223 | COLOR CODE REUSE FOR CELLULAR SYSTEMS - A method for configuring color codes in a cellular telephone network is disclosed. The method includes calculating a distance between all possible color codes to be assigned to each of the cells in the network, assigning a first code to a first base station, determining a second code corresponding to a maximum calculated distance from the first code, and assigning subsequent codes to adjacent cells as determined by the maximum available distance between the two neighboring cells' codes to help minimize cross talk and channel interference on the cellular network. | 06-18-2009 |
| 20090161528 | METHOD FOR EXTENDING RANGING REGION IN AN OFDMA SYSTEM - A method for uplink synchronization, in a wireless communication device, with a base station in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA) is disclosed. The method comprises selecting ( | 06-25-2009 |

| 20080277342 | POLYAMIDE MATRICES AND METHODS FOR THEIR PREPARATION AND USE - The invention provides novel polymer matrices and methods for preparing polymer matrices, as well as methods for purifying caustic feed streams using membranes that comprise polysulfonamide matrices. | 11-13-2008 |
| 20090000999 | RESIDENTIAL REVERSE OSMOSIS SYSTEM - A reverse osmosis system that includes a housing which receives feed water and a membrane element within the housing to filter the feed water. The membrane element includes a permeate outlet and a concentrate outlet. The reverse osmosis system further includes a sensor that monitors the condition of the water that exits from the membrane element. The reverse osmosis system further includes a first set of indicators that are located remotely from the housing. The first set of indicators showing a condition of the system based on data obtained from the sensor. The reverse osmosis system further includes a second set of indicators that are located near the housing to show a condition of the system based on data obtained from the sensor. | 01-01-2009 |
| 20090001003 | RESIDENTIAL REVERSE OSMOSIS SYSTEM - Some embodiments of the present invention relate to a reverse osmosis (RO) system that includes a housing and a pre-filter within the housing such that feed water flows into the housing and enters the pre-filter. The reverse osmosis (RO) system further includes a membrane element within the housing such that the pre-filtered water flows from the pre-filter and enters the membrane element and permeate exits the membrane element through the housing. In some embodiments, the housing includes a first end cap at one end and a second end cap at an opposing end such that feed water flows through the first end cap into the pre-filter and pre-filtered water flows from the pre-filter into the first end cap. In addition, the pre-filtered water may flow from the first end cap to the membrane element such that permeate exits the membrane element through the first end cap in order exit the housing. | 01-01-2009 |
| 20090001013 | RESIDENTIAL REVERSE OSMOSIS SYSTEM - A reverse osmosis system that includes a housing having an inlet port, a permeate port and a concentrate port. The reverse osmosis system further includes a membrane element within the housing and (i) a first connector that has an end which is connected to the inlet port; (ii) a second connector that has an end which is connected to the permeate port; and (iii) a third connector that has an end which is connected to the concentrate port. The end of the first connector fits the inlet port but does not fit the permeate port or the concentrate port. The end of the second connector fits the permeate port but does not fit the inlet port or the concentrate port. The end of the third connector fits the concentrate port but does not fit the inlet port or the permeate port. | 01-01-2009 |
| 20090008931 | RESIDENTIAL REVERSE OSMOSIS SYSTEM - A reverse osmosis system that includes a housing having an inlet port, a permeate port and a concentrate port. A membrane element is within the housing. The reverse osmosis system further includes (i) a first connector that is connected to the inlet port; (ii) a second connector that is connected to the permeate port; and (iii) a third connector that is connected to the concentrate port. A key is inserted between each of the first, second and third connectors. The key is configured such that the key cannot be inserted between the first, second and third connectors unless each of the first, second and third connectors is properly connected to the respective inlet, permeate and concentrate ports. In some embodiments, the key is configured such that the key cannot be removed from between each of the first, second and third connectors when there is pressure at the inlet port. | 01-08-2009 |
| 20110073535 | RESIDENTIAL REVERSE OSMOSIS SYSTEM - Some embodiments of the present invention relate to a reverse osmosis (RO) system that includes a housing and a pre-filter within the housing such that feed water flows into the housing and enters the pre-filter. The reverse osmosis (RO) system further includes a membrane element within the housing such that the pre-filtered water flows from the pre-filter and enters the membrane element and permeate exits the membrane element through the housing. In some embodiments, the housing includes a first end cap at one end and a second end cap at an opposing end such that feed water flows through the first end cap into the pre-filter and pre-filtered water flows from the pre-filter into the first end cap. In addition, the pre-filtered water may flow from the first end cap to the membrane element such that permeate exits the membrane element through the first end cap in order exit the housing. | 03-31-2011 |
