The present disclosure relates to combined antenna apparatus for receiving GNSS signals and other radio signals to mitigate cross-coupling.

Combined satellite navigation and radio transceiver antenna devices

Buried utility transmitters and associated locator devices, systems, and methods used for locating utility lines, pipes, and/or other conductors that are obscured from view are disclosed.

Utility locator transmitter devices, systems, and methods

Front end circuits and associated apparatus, systems, and methods for use in electronic devices such as buried utility locators are disclosed. The circuits include receivers and filters on input signals that are coupled to ground rather than differentially. A multiplexing circuit allows shared use of amplifiers, and analog-to-digital converters via a switching mechanism for selectively making or breaking electrical connection to the receiver channels for efficient sharing of electronics resources while minimizing crosstalk interference and advantageously reducing costs.

Input multiplexed signal processing apparatus and methods

Self-leveling inspection system methods and devices for use in inspecting buried pipes or other cavities are disclosed. The system includes a camera head with an image sensor, an orientation sensor, and a signal processing module including a processing programmed to receive an image from the image sensor, and an orientation signal from the orientation sensor, generate a second image based at least in part on information provided from the orientation sensor, and store the second image in a non-transitory memory.

Self-leveling inspection systems and methods

The present disclosure relates to electromagnetic marker devices for locating hidden or buried objects. One embodiment includes an antenna having a plurality of conductive windings enclosed in a housing made of a low dielectric constant material and an electronic circuit including a circuit board having circuit elements disposed thereon and electrically coupled to the conductive windings through a connector. The circuit elements receive an input signal having a first frequency from an above-ground transmitter, convert the input signal to a power supply to power up the electronic circuit, generate, in response to the input signal, an output signal having a second frequency different from the first frequency, and provide the output signal, via the antenna element, to an above-ground receiver.

Electromagnetic marker devices for buried or hidden use

Systems, devices, and methods for drain cleaning using high voltage, high frequency AC electrical power supplied through a video push-cable are disclosed. In one embodiment, a drain cleaning system may include a cable for carrying electrical control and/or data signals as well as alternating current (AC) power at a high voltage and high frequency relative to AC mains frequencies.

High frequency AC-powered drain cleaning and inspection apparatus and methods

Signal generation devices including an auto-tuning electronic circuit module for generating tuned output signals are disclosed. The auto-tuning electronic circuit module may include a tunable resonant electronic circuit element for providing a tuned output signal, including a voltage divider element and a tuning array element and control element.

Buried utility locator auto-tuning apparatus and methods

Buried object locator systems including transmitters and associated buried object locators using phase-synchronized signals are disclosed. A transmitter may generate output current signals that are phase-synchronized with a timing reference for detection by a corresponding buried utility locator that is phase-synchronized with a second timing reference.

Phase-synchronized buried object transmitter and locator methods and apparatus

Systems and methods for locating buried utilities in conjunction with associated electro-magnetic 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.

Buried utility marker devices, systems, and methods

A method for locating buried utilities in a utility locator is disclosed. The method may include receiving, at an antenna array for receiving magnetic field signals, a plurality of magnetic field signals at predefined signal frequencies in a predefined frequency suite, generating, in a receiver coupled to an output of the antenna array, a first receiver output signal, generating, in a processing element coupled to the receiver, a first set of data associated with the two or more signal components, and storing, in a non-transitory memory of the locator, the first set of data.

Locating devices, systems, and methods using frequency suites for utility detection

Antenna systems for receiving right and left hand circularly polarized signals are disclosed. An antenna system embodiment includes a top printed circuit board (PCB), a ground plane, and an antenna array including four conductive antenna elements positioned at relative zero, 90, 180, and 270 degree increments radially about a shared center point on the PCB, with each antenna element sloping upward in a left-handed direction from the ground plane towards the top PCB and connected to the ground plane and top PCB.

Antenna systems for circularly polarized radio signals

The disclosure relates to antennas for use in satellite positioning systems and other wireless bands. An antenna may include a UV resistance treated Polymethylpentene housing having enhanced dielectric properties.
