A linear motion electrical connector includes an outer component having a bore defined by an inner surface and a cylinder within the bore. The moving mechanism includes a moving actuating member, a transmitting actuating member, a transmitting string-shaped member, and a moving string-shaped member. The pilot signals may be unevenly spaced across the in-band subcarriers. The training deformation data and the training strain data are configured for use by a heuristic model to increase an accuracy of output data generated by the heuristic model. In at least one embodiment, a modified contactor is used as a contactor in the starting device.
