A sensor apparatus for a movable barrier system having a rotatable drum and an elongate member that winds up on and pays out from an external surface of the rotatable drum. The sensor apparatus includes a base portion, a sensing portion, and a controller. The sensing portion senses a first spaced apart proximity of the elongate member relative to the sensing portion and a second spaced apart proximity of the elongate member relative to the sensing portion. The controller detects a change in the proximity of the elongate member relative to the sensing portion without the elongate member contacting the sensing portion.

A reel assembly for deploying a cable, hose or umbilical connection may include an electronic control unit that may operate to control the reel assembly. A sheave that redirects the direction of the cable, hose or umbilical connection may include sensors that may measure various parameters, such as a measured line tension and/or a length of cable, hose or umbilical connection that has been deployed, and transmit the measured data to the electronic control unit. The electronic control unit may, based on received sensor data, automatically direct the operation of the reel assembly. Optionally, the sensor data and/or user control inputs and system status information may be logged. The system also may use this data to control the system, such as by activating an alarm when a certain alarm limit is exceeded by the data, adjusting parameters of the drive, and the like.

An electrical cord reel assembly can include a spool configured to wind and unwind an electrical cord therefrom. The electrical cord reel assembly can include a motor configured to rotate the spool to wind and unwind the electrical cord about the spool. The electrical cord reel assembly can include a controller in electrical communication with the motor and the electrical cord. The controller can be configured to, in response to an unwind command, place or maintain the electrical cord in a power off state. The controller can be configured to in response to the unwind command, transmit an unwind signal to the motor to cause the motor to unwind the electrical cord from the spool. The controller can be configured to automatically place the electrical cord in a power on state based at least in part on an amount of rotation of the spool during the unwinding.

A combination capillary and cable spooling system for efficiently unspooling or spooling capillary and cable with respect to a workover rig. The combination capillary and cable spooling system generally includes a motorized vehicle having a platform, a first spool support attached to the upper surface of the platform adapted to rotatably support a first spool having a capillary line, a first motor attached to the first spool support to rotate the first spool, a second spool support attached to the upper surface of the platform to rotatably support a second spool having a cable line, and a second motor attached to the second spool support to rotate the second spool.

A ceiling lift tilt management system includes first and second motor units, which are attachable to a rail system of a medical care facility. Each motor unit includes a flexible strap, which can be coiled or uncoiled within the motor unit to raise or lower a spreader bar attached thereto. Coiling or uncoiling of the straps can cause raising or lowering of a sling attached to the spreader bars. The system also allows for tilting of the spreader bars by coiling or uncoiling a leading motor unit strap. The system includes a control system that measures the relative lengths of the two straps in order to ensure that relative tilt between the spreader bars does not exceed a threshold. Once a threshold tilt for height difference is reached, further user requests for additional tilting are prohibited. Patient comfort and safety are therefore ensured.

The invention relates to an electrical cable reel. According to the invention, the reel comprises an arrangement (4) for remotely monitoring the absence of cable wound around the reel, said arrangement comprising a sensor (4A) and an electronic board connected to the sensor and linked to a remote application that is enabled.

A pipeline inspection system including a first drum including a first cable having a first camera disposed on a distal end of the first cable, where the first cable is received within an interior of the first drum and is configured to be directed into a conduit, a second drum including a second cable having a second camera disposed on a distal end of the second cable, where the second cable is received within an interior of the second drum and is configured to be directed into a conduit, and a hub housing electrical components for operation of the pipeline inspection system, where the hub is removably received in the interior of the first drum, and where the hub is selectively removable from the first drum and insertable into an interior of the second drum.

A cable reel includes a spool to extend and retract a cable that includes a first conductor. The cable reel further includes a first connector that is connected with the spool and rotates in relation to the spool. The first connector includes a first contact that is connected to the first conductor of the cable. The cable reel further includes a second connector that does not rotate. The first connector and the second connector are mateable. The second connector includes a second contact that is connected to a second conductor. The first connector and the second connector automatically mate to make an electrical connection between the first conductor of the cable and the second conductor when the first connector and the second connector are aligned in a predetermined position and at least some length of cable has been extended.

This application relates to electric winders, particularly, to an intelligent electric winder and a control method therefor. The intelligent electric winder includes a support, a control unit and a winder body, where the winder body includes a casing, a winding reel, a drive structure, and a cable. The drive structure is electrically connected to the control unit. The control unit includes: a socket and a host; the host is arranged inside the casing, and the socket is arranged outside the casing; a start/stop button is provided on a surface of the socket, and the socket is connected to a free end of the cable. Through the intelligent electric winder and a control method therefor, the winding reel is controlled to start or stop winding by sending a wireless control signal, so that the intelligent electric winder is controlled to wind or unwind cables through the wireless communication.

An aerial spraying apparatus (unmanned aerial vehicle system) includes one or more drones (unmanned aerial vehicles), and a station on the ground that is connected by wire to at least one of the one or more drones. Each of the one or more drones is equipped with a drone side cable connected to the station or another drone, and a drone side cable mechanism that performs paying out or pulling in of the drone side cable.
