| 20090080338 | SYSTEMS AND METHODS FOR FLOW MIRRORING WITH NETWORK-SCOPED CONNECTION-ORIENTED SINK - Systems and methods for sinking port mirrored from one or more identified flows of data to any node in a network are provided. Moreover, the network is configured to convey the mirrored data to the sink, without the need for any facilities expressly dedicated for this purpose. The present invention removes the requirement to co-locate the sink port within the same logical node. The present invention uses a mirrored flow configured as a provisioned layer two point-to-point connection, such as a Switched Permanent Virtual Circuit (SPVC), Pseudo-Wire (PWE3), a Virtual Local Area Network (VLAN) cross-connect, Provider Backbone Bridging—Traffic Engineering (PBB-TE), and the like. The node with the mirrored port is configured to create copies of the appropriate set of packets (i.e., ingress, egress packets, or both based on provisioning and based on the identified flow), and to forward the packets to the sink port through the provisioned point-to-point connection. | 03-26-2009 |

| 20110073740 | Book holder - Holder consists of a base connected to fences at each end. Legs, one at each side of the base, are attached to the base at the movable fence end. Deploying legs positions the base in an acceptable book reading angle with the movable fence upward. Books, hard or soft cover, are held in place on the base by the inside edges of page tab assemblies which are spring loaded to the fences through elongated slots. Tabs are adjusted to hold down pages of a book by moving them perpendicularity and/or side to side over each side of an opened book's pages. Further tab adjustments needed to obtain a clear field of reading vision is obtain by rotating the tab page retainers. Page turning is accomplished without further adjustment or movement of the tab assembly. | 03-31-2011 |

| 20100144278 | METHOD AND SYSTEM FOR SELECTING, TRANSMITTING, AND RECEIVING AN UNUSED CARRIER FREQUENCY AND TRANSMITTING OVER THE UNUSED CARRIER FREQUENCY - Some embodiments concern a method of transmitting electrical signals. The method can include: using a global positioning satellite receiver to determine a first location of a first electrical device; using a first transmitter to transmit the first location to a first server; using a receiver to receive information identifying at least one first unused frequency at the first location from the first server; selecting a first transmission frequency from the at least one first unused frequency; and communicating the first transmission frequency to a user. Other embodiments are disclosed in this application. | 06-10-2010 |

| 20110017312 | Fluid-Pressure Regulator and Related Methods and Systems - A fluid-pressure regulator for regulating the pressure of a fluid. The regulator includes a variable-resistance fluid element and a variable-volume fluid element located downstream of the variable-resistance element. Pressure in the fluid at the outlet of the regulator is controlled by substantially simultaneously changing the resistance of the variable-resistance element and the volume of the variable-volume element. In one example, a decrease in pressure is effected at the outlet by simultaneously increasing the resistance of the variable-resistance element and increasing the volume of the variable-volume element. Some embodiments of the regulator are particularly useful to effect long-term and high-speed pressure changes in high-resistance fluidic channel networks. | 01-27-2011 |

| 20090152006 | DUAL STRIPPER RUBBER CARTRIDGE WITH LEAK DETECTION - A rotating control drilling device includes an upper sealing element and a lower sealing element positioned around a drillstring and forming a chamber therebetween and a leak detection device. The leak detection device includes a piston in communication with the chamber, a magnet disc disposed on an end of the piston, and a plurality of magnetic sensors arranged in a magnetic sensing ring around the rotating control drilling device. Upon reaching a selected critical pressure in the chamber, a spring is configured to compress as the magnet disc is positioned proximate to the plurality of magnetic sensors. Furthermore, a method to detect leaks in a rotating control device includes positioning a leak detection device in communication with a chamber located between upper and lower sealing elements and signaling with the leak detection device when a pressure of the chamber exceeds a selected critical pressure. | 06-18-2009 |
