Abstract: Cable handling devices, methods and systems are provided for securing and deploying, or retracting, one or more cables or hoses into or out of a pipe or cavity allowing inspection of the pipe or cavity. The cables and/or hoses may be coupled and moved together, or decoupled enabling them to be moved independently. A hand-held device with a housing for at least partially enclosing one or more cables or hoses, at least one coupling mechanism integrally attached to the housing, and a coupling control for coupling and decoupling the one or more cables or hoses may be provided. One or more of the cables may be connected to a camera disposed at the distal end of a cable thereby facilitating inspection of the pipe or cavity. Tools such as cutting devices or a jetter may be provided at the end of the one or more cables and/or hoses.

Abstract: Magnetic locators and uses of such locators for detection of buried utilities are disclosed. Outputs provided from two or more three three-axis magnetic sensors based on magnetic field signals sensed at single points in space in three axes may be used to determine information about the buried utilities including position and/or depth of the buried utilities relative to the locator.

Abstract: Systems for locating hidden utilities including a portable locator and associated portable transmitter are disclosed. The portable locator may include a magnetic field measurement module for determining a current signal in the hidden utility based on a received magnetic field, and a receiver module for receiving data from the portable transmitter. The portable transmitter may include a data transmitter module for wirelessly sending information associated with a current signal provided to the hidden utility to the portable receiver module. The portable receiver may be configured to measure a relative change in magnetic field angles, and determine an amount of cross coupling to adjacent utilities based at least in part on the measured magnetic field angles.

Abstract: Submersible lights including housings and a multilayer stack for pressure transfer are disclosed. A transparent pressure-bearing window, a window support structure, a circuit element populated with LEDs, and a pressure support structure may be mounted inside the housing. The support structure may be structured to bear at least some of the pressure applied to the transparent window from external pressure sources. The support structures may also be adapted to transfer thermal energy to an exterior environment such as sea water.

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: 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.
