Abstract
Examples are disclosed that relate to power supply devices and methods for adjusting a length of a device cable extending from the power supply device. In one example a method comprises, at a power supply device comprising a device cable, determining a cable property of the device cable. Based at least in part on the cable property of the device cable, actuating a motor in the power supply device to change the length of the device cable extending from the power supply device.

At a power supply device comprising a device cable, a method for adjusting a length of the device cable extending from the power supply device, the method comprising:
- determining a cable property of the device cable;
- based at least in part on the cable property of the device cable, actuating a motor in the power supply device to retract the device cable into the power supply device;
- and
- based at least in part on a bending strain of the device cable reaching a target bending strain, ceasing retracting the device cable into the power supply device.
A power supply device, comprising:
- an enclosure;
- a device cable spool in the enclosure;
- a device cable affixed to the device cable spool and extending from the enclosure;
- a motor coupled to the device cable spool;
- a processor;
- and
- memory storing instructions executable by the processor to:
- determine a cable property of the device cable;
- based at least in part on the cable property of the device cable, actuate the motor to rotate the device cable spool to retract the device cable into the power supply device;
- and
- based at least in part on a bending strain of the device cable reaching a target bending strain, cease retracting the device cable into the power supply device.
At a power supply device comprising a device cable and a force sensor, the device cable comprising a strain gauge, a method for adjusting a length of the device cable, the method comprising:
- utilizing the force sensor to determine a tension of the device cable;
- utilizing the strain gauge to determine a bending strain of the device cable;
- and
- based at least in part on the tension and the bending strain of the device cable, actuating a motor in the power supply device to change the length of the device cable extending from the power supply device.
