摘要： 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.

摘要： 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.

摘要： Systems 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 different from the first frequency. The generated output signal may be tuned by a second resonant circuit and provided to the marker device antenna.
