A hub for use with a pipeline inspection device including a reel and a cable disposed at least partially within the reel, the cable including a camera. The the hub includes a body configured to be selectively coupled to the reel, a mating member positioned on the body, where the mating member is configured to removably secure the body to the reel, a wireless communication module positioned within the body, where the wireless communication module is configured to create a wireless connection between the hub and a remote device including a display, a battery receptacle on the body, and a battery removably coupled to the battery receptacle, the battery configured to provide power to the camera.

A reel system can include a reel rotatable around a first axis to receive or deploy a windable line a frame supporting the reel, a base supporting the frame, and a bearing assembly. The bearing assembly can include a first member connected to the base and a second member connected to the frame and rotatably engaged with the first member to enable relative rotation between the frame and the base around a second axis.

A feeding device for feeding an optical fiber from a coil and for recoiling unused fiber for use in an apparatus for measuring the temperature of a melt is provided. The feeding device includes a support for a coil, a feeding mechanism for decoiling the optical fiber from the coil and recoiling the optical fiber, at least one motor for driving the feeding mechanism, and a load for the optical fiber which avoids a spring back effect of the optical fiber from the coil. Blockage is avoided when decoiling and recoiling the optical fiber from the coil.

An asymmetric bearing device automatically decreases, without the need for manual adjustment, an amount of friction exerted against rotation of a drum or other mechanism upon reversal of the direction of rotation of the drum.

The present disclosure relates to an evacuation guidance device for rescue, and more particularly, to an evacuation guidance device for rescue, which is capable of securing an evacuation route through a linear illuminator to guide an evacuee to a safety zone and bidirectionally communicating with a rescue agent to evaluate a rescue situation, when an emergency situation occurs in a building due to fire, power failure, a gas leakage, and the like. In the evacuation guidance device for rescue according to the present disclosure, a position of the bobbin unit may be identified through the first and second position notifying luminescence members so that there is an advantage in which position determination of the evacuee or the rescue agent may be easy.

This invention is directed toward a portable and easy to set up retractable cord system with means to allow athletes to move along specified routes and to form space indicators that show zone areas.

A large diameter lay-flat hose spool apparatus has a mobile platform with a chassis and wheels. Side supports extend up from the chassis. An axle bears on the side supports, spanning a gap therebetween. Plural spools are rotatably mounted on the axle. Each spool has at least one rim and a length of lay-flat hose wound thereon. A driver rotates the individual spools about the axle independently of the other spools. The driver has a first actuator that moves a drive wheel into and out of contact with a rim of one of the spools. The driver has a second actuator that moves the drive wheel from one of the spool rims to another of the spool rims. A motor rotates the drive wheel. A controller system operated the motor, the first actuator and the second actuator.

An electrical cable reel module for a drone includes a bracket adapted to be firmly fixed to the drone. A reel body is movably and rotatably mounted on the bracket. A first driving device is mounted on one side of the bracket to drive the reel body to rotate and a second driving device is mounted on the other side of the bracket to drive the reel body to move linearly in a first direction. A third driving device is mounted on the bracket to drive the reel body to move linearly in a second direction opposite to that of the first direction. At least one positioning device is mounted among the reel body, the first driving device and the second driving device to selectively drive the reel body to rotate and prevent the reel body from movement and rotation.

A Retractable Electrical Trailer Connection System comprising a retractable reel assembly removably mounted to a trailer; an electrical cable, further comprising a first end and a second end; an electrical connector electrically coupled to the electrical cable second end; a guide aperture extending outwardly from the retractable reel assembly, and a stop mechanism removably attached to the electrical cable between the guide aperture and the electrical connector. The electrical cable first end is electrically coupled to the trailer and is wound about a center spool of the retractable reel assembly where the electrical cable second end extends outwardly through the guide aperture. The electrical connector is configured to electrically couple the electrical cable to a standard receptacle located on a rear side of a tow vehicle. The stop mechanism is preferably structured to move along the electrical cable and lock into place.

A magnetic retractable line divider may include at least a reel assembly having a shell, and a magnetic portion is installed thereon. An elastic line divider belt is wound on the reel assembly, and a magnetic member is connected to a lateral end of the line divider belt. The line divider belt is configured to be horizontally pulled out from the reel assembly and travel a preferred distance to attach to a magnetic object, thus achieving line divider effect. Moreover, when someone pushes against the line divider belt with or over a preferred force, the magnetic member is configured to be detached from the magnetic object and automatically retracted into the reel assembly, thus avoiding accident.
