Abstract
Various embodiments related to a cart movement detection system for a dynamics track are disclosed. One disclosed embodiment includes a cart movement detection system for a cart on a dynamics track comprising an encoder system comprising a sensor system on the cart configured to read an encoder scale on the dynamics track and produce quadrature outputs representing an increment of movement of the cart on the dynamics track. The encoder system is further configured to obtain and encode pulse information from the quadrature outputs and transmit the encoded pulse information over an infrared channel. The cart movement detection system further includes a receiver system configured to receive the encoded pulse information transmitted over the infrared channel from the encoder system and determine from the encoded pulse information a direction of the increment of movement of the cart.
