Abstract: Systems and methods for locating buried utilities in conjunction with associated electromagnetic marker devices are disclosed. A marker device may include a marker device antenna and an electronic circuit operatively coupled to the marker device antenna. The electronic circuit may include at least two resonant circuits, including a first resonant circuit formed in combination with the marker device antenna for receiving an excitation signal at a first frequency from a marker excitation device. The received excitation signal may be converted into a power supply by a power circuit for powering the electronic circuit. Responsive to the received excitation signal, a processing element provided in the electronic circuit may generate an output signal at a second frequency, which is substantially different from the first frequency. The generated output signal may be tuned by a second resonant circuit and provided to the marker device antenna.

Abstract: Slim profile magnetic user interface devices (slim UIDs) are disclosed. A slim UID may include a slim profile housing, a movable actuator assembly having user contact surfaces on opposite sides, along with a magnet, magnetic sensor, restoration element, and processing element. User mechanical interaction with the actuator element may be sensed by the magnetic sensor and processed to generate output signals usable by a coupled electronic computing system.

Abstract: Location systems and methods for locating paint and other markings on a surface are disclosed. A paint marking stick may include a magnetic field sonde that is actuated in conjunction with dispensing of paint or other markers, where the sonde generates a magnetic field signal in conjunction with dispensing of paint or placement of a marker. A corresponding utility locator may receive the sonde magnetic field dipole signal and determine and store positional information and type information associated with the paint or other marker.
