Abstract: A device includes a first sensor and a second sensor. The first sensor is configured to generate a first signal corresponding to a detected first force. The second sensor is configured to generate a second signal corresponding to a detected second force. The first force and the second force has a substantially common direction. The device includes a processor configured to determine a measure of tension using the first signal and using the second signal. The measure of tension corresponds to displacement of an elongate member.
