A vehicle includes an auxiliary battery configured to power an electrical accessory, a traction battery configured to provide power to propel the vehicle, a winch including a motor and cable, and a controller configured to, responsive to a requested torque of the motor being less than a threshold, initiate transfer of power to the motor from the auxiliary battery, and initiate transfer of power to the motor from the traction battery otherwise.

Systems and methods can be used in connection with a wellbore environment for automatically controlling wire being spooled around a drum. A system comprising a spooler, a sensor assembly, and a communication link can be used to adjust the position of wire being spooled around a drum. A first motor can control the spooler and a second motor can control the sensor assembly. The spooler can be positioned to control spooling of wire around the drum as the drum rotates to reel in wire. The sensor assembly can be configured to detect a distance between the sensor assembly and the wire being spooled. A communication link can communicatively couple the sensor assembly with the first motor and the second motor to control movement of the spooler and the sensor assembly relative to the drum based on the distance detected by the sensor assembly.

A device in connection with a hoisting rope of a hoisting device includes a main suspension element to suspend a sheave or wedge socket supporting the hoisting rope to a fastening structure of a body of the hoisting device and a detector for detecting an external vertical force acting on the hoisting rope.

A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

An automatically opening and closing inflatable holiday ornament includes a box that has a base, a plurality of side panels hingedly connected to the base, and a top portion connected to each of the plurality of side panels. The ornament further includes a motor, a plurality of pull cables, such that each of the plurality of pull cables has a first end operatively connected to the motor and a second end connected to one of the plurality of side panels. The ornament also includes a first blower, an inflatable disposed in the box and surrounding the first blower such that operation of the first blower blows air into the inflatable to inflate the inflatable, and a controller operatively connected to the motor and to the first blower such that the controller controls operation of the motor and the blower.
