Abstract: An Entertaining Growth System that utilizes the growth of a seedling within its design to create an entertaining and interesting device of chance. In its simplest form it allows the user to ask a “question” of the Entertaining Growth System and receive an “Answer” by observing the Dynamic Growth of a plant, in this case as seedling, through labeled holes in a lid.

Abstract: Apparatus and method for indicating mechanical stiffness properties of body tissue employing Doppler imaging techniques. Ultrasonic signals that are transmitted to the target not only are reflected for developing images of the target from the reflections, but, by appropriate selection of the intensity of the transmitted signals, the body tissue being investigated is deformed or moved when the transmitted signals impinge on the target. The deformation or movement of the body tissue being investigated is imaged and is representative of the mechanical stiffness of this body tissue.

Abstract: Method and apparatus for destroying aberrant electrical pathways in the myocardium of the heart by creating lesions in the myocardium by ablation of the myocardium with a focused ultrasound beam.

Abstract: Determining the locations of therapeutic seeds implanted in a body part by distinguishing the therapeutic seeds from the body part by imposing physical changes on the therapeutic seeds and sensing these physical changes in the therapeutic seeds. In one form of the invention, the therapeutic seeds are partially ferromagnetic and are caused to vibrate by a magnetic field and the vibrating therapeutic seeds are identified by reflections of ultrasonic signals transmitted to the therapeutic seeds.
