Systems, methods and apparatus for a tank inspection vehicle and a tether management system (TMS) are disclosed. The tank inspection vehicle is connected to the TMS via a negatively buoyant tether. The TMS is also connected to a power source external to a tank via a power and communications cable. The TMS selectively connects the vehicle to the power source via the tether and the power and communications cable. The TMS may include a frame, a float, a reel, a reel mechanism, a float switch, one or more sensors, and a control unit having one or more processors communicable with one or more memories. The TMS is configured to reel or unreel the tether in response to the movement of the vehicle and provide power to the vehicle when the TMS, vehicle, and the components thereof are submerged in a flammable fluid.

A fish tape tool includes a housing including a base and a cover. The housing defines a chamber between the base and the cover. The base defines an exit opening and a channel extending from the chamber to the exit opening. The fish tape tool also includes a drum configured to be inserted into the chamber of the housing, the drum containing a fish tape. The drum is configured to be manually rotatable relative to the housing to dispense or retract the fish tape from the housing via the channel and the exit opening. The cover defines a central aperture that is aligned with a central bore of the drum.

Provided is a yarn spindle coding method including: when determining that yarn spindles are fully wound, sleeving the yarn spindles in the winding machine sequentially outside a yarn connecting rod of a doffer, and updating the number of unloading times of the winding machine and recording first doffing time of each yarn spindle; generating a first information code of each yarn spindle based on identification information of the winding machine, the updated number of unloading times, the first doffing time and position information of each yarn spindle; and sending each first information code to the doffer, so that the doffer determines a corresponding target yarn spindle among the yarn spindles according to a matching degree between the first doffing time and second doffing time of each yarn spindle recorded by the doffer and code the information code on a corresponding target yarn spindle.

A fish tape tool may include a housing including a handle. A fish tape tool may include a drum configured to be removably coupled to the housing, the drum containing a fish tape, the drum including a frame and a drum portion that is rotatable relative to the frame, wherein at least a portion of the frame and at least a portion of the drum portion each remain exposed when the drum is coupled to the housing.

A modular material tracking system is provided for tracking material stored on and drawn from a reel using a modular system. The modular material tracking system may include a detection element, digital logic components, location receiver, enclosure, analytic components, interface component, sensor module, and plate module. One or more sensors relative to the reel may detect a position indicative of forward or reverse reel rotation. A processor may analyze signals to count rotations of the reel, which is savable in memory. A battery may provide power. The system may also record the time and location associated with rotations. A method for tracking material stored on and drawn from a reel using a modular material tracking system is also provided.
