| 20080246507 | Body Capacitance Electric Field Powered Device For High Voltage Lines - Devices that couple to high voltage transmission lines obtain power themselves using the body capacitance of an element of the devices. The devices generate a comparatively lower voltage from the current flowing between the high voltage line and the element of the device that generates the body capacitance. The devices can be used to operate sensors that monitor the transmission lines or parameters of the power distribution system, such as current, line temperature, vibration, and the like. The devices can also be used as indicators, such as aircraft warning lights, information signs, etc. In addition, the devices can operate as RF transmission/reception or repeater devices, radar devices, mesh networking nodes, video/audio surveillance, sound emitting devices for scaring animals, drones that traverse the power line, etc. Because the devices operate in response to line voltage rather than current, the devices are reliable even in low current conditions. | 10-09-2008 |

| 20110156697 | COMPACT, TWO STAGE, ZERO FLUX ELECTRONICALLY COMPENSATED CURRENT OR VOLTAGE TRANSDUCER EMPLOYING DUAL MAGNETIC CORES HAVING SUBSTANTIALLY DISSIMILAR MAGNETIC CHARACTERISTICS - A device for sensing electrical current or voltage in an electrical distribution system using an actively compensated current ratio transformer that includes a first magnetic core having a first permeability and a second magnetic core having a second permeability higher than the first permeability. A primary winding having P turns is coupled with the first and second magnetic cores, a measurement winding having M turns is coupled with the first and second magnetic cores so that current in the primary winding induces current in the measurement winding, and a sense winding having S turns is coupled with the second magnetic core. An amplifier coupled to the sense winding receives a voltage developed across the sense winding and produces a compensation current in response to the received voltage. The amplifier has an output coupled to the sense winding to feed the compensation current through the sense winding to reduce the voltage developed across the sense winding voltage to substantially zero. A burden resistor is coupled to the measurement winding and the sense winding for receiving the sum of the current induced in the measurement winding and the compensation current. | 06-30-2011 |

| 20100189514 | BALLAST-FILLED PIPELINE WEIGHT - A flexible bag-type pipeline weight, configured to straddle a pipeline, has internal tie means to prevent excessive bulging of the weight after being filled with ballasting material, thus facilitating installation in narrow trenches. Built-in loading loops facilitate filling the weight with ballasting material without need for special loading equipment. The bag-type pipeline weight is formed with a pair of leg sections on either side of a Central, pipeline-receiving recess. Once filled with ballast, the legs remain separated, thus facilitating installation on a pipeline. The filled pipeline weight is also freestanding and stable for purposes of transport and storage prior to installation. Hoisting slings facilitate lifting and manipulation of loaded pipeline weights without the need for spreader bars. | 07-29-2010 |

| 20110048950 | METHODS AND APPARATUS FOR PARTICLE INTRODUCTION AND RECOVERY - Particles may be injected into a matrix for concentration by scodaphoresis using a quadrupole injection field. Particles may be injected from two or more sample chambers simultaneously. Particle injection may be performed simultaneously with performing scodaphoresis. In some embodiments the particles are concentrated into a well containing fluid. The well can extend out of a plane of the matrix. Altering the relative phases of components of a scodaphoresis field permits concentration of selected particles and exclusion of other particles. Scodaphoresis methods may be applied to DNA, other bio-molecules and other particles. | 03-03-2011 |

| 20090074816 | TISSUE TARGETED ANTIGENIC ACTIVATION OF THE IMMUNE RESPONSE TO CANCERS - The invention provides in part methods of treating cancers of a specific organ or tissue by administering a composition that is antigenically specific for one or more microbes that are pathogenic in the specific organ or tissue in which the cancer is situated. The formulations of the invention thereby facilitate activation of a treatment response to a cancer in a particular tissue or organ. The compositions may for example include killed or attenuated microbial pathogens, and may be administered at sites distant from the cancer, for example the skin. In some embodiments, microbial species of endogenous flora that are known to cause infection in the relevant organ or tissue may be used in the formulation of the antigenic compositions. In alternative embodiments, exogenous microbial pathogens that are known to cause infection in the relevant organ or tissue may be used in the formulation of the antigenic compositions. The administration of the immunogenic compositions may be repeated relatively frequently over a relatively long period of time. In embodiments for intradermal or subcutaneous injection, dosages may be adjusted so that injections reproduce a consistent visible delayed inflammatory immune reaction at the successive site or sites of administration. | 03-19-2009 |
| 20110010655 | METHOD, SYSTEM AND MEDIA FOR ENTERING DATA IN A PERSONAL COMPUTING DEVICE - In one aspect of the present invention a user can rapidly enter and search for data, such as text, using a data entry system by entering one or more characters on a digital keyboard with a pointing device. With the digital keyboard the user can create words, phrases and other character sequences. As the user enters a character sequence, a mechanism for character prediction visually informs the user of which set of characters on the digital keyboard are most likely to have the character that the user wishes to next enter as part of the text. In another aspect of the present invention, as the user forms a character sequence (partial text entry), the character sequence is used to search a dictionary for a set of completion candidates that begin with the character sequence. The data entry system retrieves completion candidates from the dictionary by determining which completion candidates in the dictionary are more likely to be the ones that the user is attempting to type. A rapid navigation system provides for enhanced navigation and retrieval of completion candidates from the dictionary. | 01-13-2011 |
| 20110020401 | TISSUE TARGETED ANTIGENIC ACTIVATION OF THE IMMUNE RESPONSE TO TREAT CANCERS - The invention provides in part methods of treating cancers of a specific organ or tissue by administering a composition that is antigenically specific for one or more microbes that are pathogenic in the specific organ or tissue in which the cancer is situated. The formulations of the invention thereby facilitate activation of an immune response to a cancer in a particular tissue or organ. The compositions may for example include killed or attenuated microbial pathogens, such as whole killed bacterial cells, and may be administered at sites distant from the cancer, for example the skin. In some embodiments, microbial species of endogenous flora that are known to cause infection in the relevant organ or tissue may be used in the formulation of the antigenic compositions. In alternative embodiments, exogenous microbial pathogens that are known to cause infection in the relevant organ or tissue may be used in the formulation of the antigenic compositions. The administration of the immunogenic compositions may be repeated relatively frequently over a relatively long period of time. In embodiments for intradermal or subcutaneous injection, dosages may be adjusted so that injections reproduce a consistent, visible, delayed inflammatory immune reaction at the successive site or sites of administration. | 01-27-2011 |
