    Abstract: In a first preferred embodiment, the invention includes a method of tracking displacements between ultrasound images by calculating a coarse displacement estimate, and calculating a fine displacement estimate using images and coarse displacement estimate. In a second preferred embodiment, the invention includes a method of calculating a coarse displacement estimate from images by reducing the resolution of the images, correlating the reduced resolution images, and calculating the location of the peak of the correlation function. In a third preferred embodiment, the invention includes a method of calculating a finer displacement estimate from images by using a coarse displacement estimate with correlation processing of the images and calculating the location of the peak value of the correlation function.

    Abstract: A steering drive mechanism utilizes a pair of planetary gear arrangements between the input (or engine drive shaft) and the output shafts driving each wheel of a vehicle. The input is supplied to each sun gear in equal magnitude but opposite direction to account for driving the left or right wheels. The output shafts are connected to the planet carriers. In normal straight line driving, the ring gears are held fixed. The drive mechanism further comprises a steering motor that drives a steering gear that meshes with each ring gear. When the steering motor is activated, the steering gear rotates each ring gear in the same direction, so that the ring gear for one side increases the speed of the planet carrier and output shaft, while the ring gear for the opposite side decreases the output shaft speed. In this way, the turn can be executed without any appreciable reduction in vehicle speed. This steering drive mechanism also eliminates the need for complex differential gearing.
