Abstract: Winch (304) has a load bearing tape (305) to advance into a borehole (307). Hole depth can be determined by subtracting a sensed height (310) above ground surface (311) from total depth (312) measured. Can include a height above ground sensor (314) and a tape distance measurer (316). Depth of water or watery mud or muddy water (320) can be sensed, such as by a pressure sensor (326) on a weight or in a sensor device at or near the tape leading end. A heater (309) can warm the tape. A cover or housing (313) can be provided for the winch or spool. The tape can include wires or fibre optics (336) embedded in or applied to a surface of the tape (305) and/or apertures or embedded or surface applied markers/indicators (338) along a length thereof e.g. for reading by an optical or magnetic sensor.

Abstract: 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.

Abstract: A method for determining depth of a material is disclosed. The method includes transmitting a signal from an antenna at a location. The signal includes a fundamental frequency and the signal penetrates ground under the location. The location is selected to locate a material at a depth under the location. The fundamental frequency matches a known resonant frequency of a resonant atom of a molecule of the material. The method includes detecting a reflected wave on the antenna, determining a time difference between transmission of the signal and detection of the reflected wave on the antenna, and determining the depth to the material based on the time difference and a reflected velocity corresponding to the resonant atom.

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: Repaired rotors are provided. The rotors are repaired by using an indenter apparatus for plastically straining original portions of the rotor and adjacent repair welds. The weld nugget, adjacent heat affected zones, and the adjacent parent-metal portions or new metal portions, are indented at a weld nugget and heat affected zone, to produce threshold levels of uniform plastic strain which meet or exceed plastic strain levels that provide, when the weld nugget and heat affected zone is heat treated, a recrystallized grain structure metallurgically comparable to the grain structure of the original parent-metal of the rotor. Repaired integrally bladed rotors for gas turbine engines, such as aircraft engines, are provided. Blades for gas turbine engines, including integrally bladed rotors, may be advantageously provided, having been manufactured or repaired as described.

Abstract: A tread portion of a pneumatic tire includes a columnar wear measurement magnet that has magnetic flux density or magnetic field strength formed thereby decreased due to wear thereof along with wear of tread rubber of the tread portion and a columnar reference magnet provided at a position where the columnar reference magnet is not worn with the wear of the tread rubber. The wear measurement magnet and the reference magnet extend from a tread surface side toward a tire cavity region of the pneumatic tire, and an end of the reference magnet on the tread surface side is located farther from a tread surface where the tread portion contacts the ground than an end of the wear measurement magnet on the tread surface side.

Abstract: A tire tread detection apparatus and tire pressure detector setting apparatus with tire tread detection function are provided. The tire tread detection apparatus includes a body casing, a driving unit, a measuring member, a position member, and a sense member. The driving unit, the measuring member, and the positioning member are connected. The driving unit is applied for driving the measuring member to protrude outward from the body casing for measuring the tire tread depth of the tire. The sense member generates a measurement signal corresponding to the positioning member, such that the measurement signal indicates a tire tread depth value. Therefore, the tire tread depth is efficiently and accurately acquired.
