The present invention provides a method and apparatus for recording motion of a vehicle or a fixed structure with a self-contained motion recorder apparatus. The self-contained motion recorder apparatus is a sealed unit that contains a power source together with controller, sensor and recording devices. The controller device includes a power consumption manager that manages and conserves the overall power consumption of the apparatus. A sensor device is further included in operable communication with the controller device that produces signals that represent the motion of the vehicle or structure as a function of time. Additionally, a recording element is provided in operable communication with the controller for storing data that corresponds to the signals. A communication interface is further provided such that data may be read from the apparatus and commands and data may be written into the apparatus, from an external device.

A controller for controlling supply of electrical current to the coils or coil groups of an electromagnetic retarder for applying drag torque to a turning shaft or drive line. The controller includes an input signal receiving element for receiving input signals from at least one input device, a control unit responsive to the input signal for modulating electrical current supply from at least one current source to the retarder coils so that current is distributed to each of the coils or coil groups substantially equally.
