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 |

20130170907 | LIGHTWEIGHT SUPPORT MAT FOR EQUIPMENT AND VEHICLES - A lightweight rig mat comprises a cellular soil stabilization material, with a plastic foam injected into the cells of the cellular material to provide required load-carrying capacity. The cellular material is preferably treated with a bonding agent to promote a structural bond between the plastic foam and the cellular material, thereby enhancing the overall shear strength, structural integrity, and flexural rigidity of the mat. The cell walls may also have textured surfaces to enhance the bond with the foam. The walls between the cells in the cellular material may have perforations to permit foam to flow between cells during the foam-injection process. The mat may be formed with connector pockets to facilitate interconnection of adjacent mats using suitable connection means, so as to prevent lateral separation between mats while allowing articulation between adjacent mats to accommodate irregular ground surfaces. | 07-04-2013 |

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 |
