20130127470 | BURIED OBJECT LOCATOR APPARATUS AND SYSTEMS - Buried object locators including various antenna configurations and safety features are disclosed. In one embodiment a locator includes a body, one or more antenna nodes coupled to the body, and a safety light assembly disposed on or within the body. The locator may further include a surface light assembly and camera and/or one or more GPS and/or ISM antennas and receiver/sensor modules. The antenna nodes may be gradient and/or dodecahedral antenna nodes. | 05-23-2013 |
20140111208 | GROUND-TRACKING SYSTEMS AND APPARATUS - A ground tracking system including a ground follower assembly for use with a locator or other device for determining position, motion, and/or orientation information is disclosed. The ground follower assembly may include a wheel assembly coupled to a locator and configured to swivel and/or pivot relative to an antenna node of the locator to generate signals for use in determining position information during a locate operation, such as from a sonde array. | 04-24-2014 |
20140111376 | DUAL ANTENNA SYSTEMS WITH VARIABLE POLARIZATION - Antenna systems for receiving transmitted signals comprising at least a first tuned antenna disposed in a known relationship spatially with a second antenna, with the first tuned antenna electrically connected to the second antenna, are disclosed. The antenna system may be configured to allow the antennas to reliably discriminate between left-hand and right-hand polarized circular signals. | 04-24-2014 |
20140132269 | MULTI-FREQUENCY LOCATING SYSTEMS AND METHODS - Multi-frequency buried object location system transmitters and locators are disclosed. A transmitter may generate and provide output signals to a buried object at a plurality of frequencies, which may be selected based on a connection type. Corresponding locators may simultaneously receive a plurality of magnetic field signals emitted from the buried object and generate visual and/or audible output information based at least in part on the plurality of received magnetic field signals. The visual and/or audible output may be further based on signals received from a quad-gradient antenna array. | 05-15-2014 |
20140132270 | QUAD-GRADIENT COILS FOR USE IN LOCATING SYSTEMS - Buried object locators including an omnidirectional antenna array and a quad gradient array are disclosed. A locator display may include information associated with a buried object based on both omnidirectional antenna array signals and quad gradient antenna array signals. | 05-15-2014 |
20140139223 | GRADIENT ANTENNA COILS AND ARRAYS FOR USE IN LOCATING SYSTEMS - Buried object locators including an omnidirectional antenna array and a gradient array are disclosed. A locator display may include information associated with a buried object based on both omnidirectional antenna array signals and gradient antenna array signals. | 05-22-2014 |
20140191759 | MULTI-FREQUENCY LOCATING SYSTEMS AND METHODS - Multi-frequency buried object location system transmitters and locators are disclosed. A transmitter may generate and provide output signals to a buried object at a plurality of frequencies, which may be selected based on a connection type. Corresponding locators may simultaneously receive a plurality of magnetic field signals emitted from the buried object and generate visual and/or audible output information based at least in part on the plurality of received magnetic field signals. The visual and/or audible output may be further based on signals received from a quad-gradient antenna array. | 07-10-2014 |
20140285203 | GROUND-TRACKING SYSTEMS AND APPARATUS - A ground tracking system including a ground follower assembly for use with a locator or other device for determining position, motion, and/or orientation information is disclosed. The ground follower assembly may include a wheel assembly coupled to a locator and configured to swivel and/or pivot relative to an antenna node of the locator to generate signals for use in determining position information during a locate operation, such as from a sonde array. | 09-25-2014 |
20140312903 | MULTI-FREQUENCY LOCATING SYSTEMS AND METHODS - Multi-frequency buried object location system transmitters and locators are disclosed. A transmitter may generate and provide output signals to a buried object at a plurality of frequencies, which may be selected based on a connection type. Corresponding locators may simultaneously receive a plurality of magnetic field signals emitted from the buried object and generate visual and/or audible output information based at least in part on the plurality of received magnetic field signals. The visual and/or audible output may be further based on signals received from a quad-gradient antenna array. | 10-23-2014 |
20150055005 | CABLE STORAGE DRUM WITH MOVEABLE CCU DOCKING APPARATUS - Embodiments of video inspection systems with moveably dockable CCUs are disclosed. In one embodiment a video inspection system includes a frame element, a camera control unit (CCU), and a docking apparatus mechanically coupled to the frame element and/or the CCU so as to allow the CCU to rotate relative to the frame, about a rotational axis, responsive to a user action. | 02-26-2015 |
