Abstract: A torque sensor can measure torque introduced into an upper shaft that is rotatable around a longitudinal axis and is connectable to a lower shaft via a torsion rod. A first component is connectable to the upper shaft, and a second component is connectable to the lower shaft. The components have surfaces that protrude in a longitudinal direction and at least partially overlap. A sensor coil that can generate a high-frequency alternating magnetic field is arranged on one of the surfaces of one component, and a metallic element is arranged on one of the surfaces of the other component. A torque introduced into the upper shaft causes a change in distance between the sensor coil and the metallic element. A device can measure a frequency change of the alternating magnetic field caused by the change in distance and determine the torque introduced into the upper shaft.

Abstract: Focused acoustic radiation, referred to as tonebursts, are applied to a volume of liquid to generate a set of droplets. The droplets generated are substantially smaller in scale than the focal spot size of the acoustic beam (e.g., the frequency at which the acoustic transducer operates). Further, the droplets have trajectories that are substantially in the direction of the acoustic beam propagation direction. In one embodiment, a first toneburst is applied to temporarily raise a protuberance on a free surface of the fluid. After the protuberance has reached a certain state, a second toneburst is applied to the protuberance to break it into very small droplets. In one embodiment, the state of the protuberance at which the second toneburst is supplied is the time period shortly after the protuberance reaches its maximum height but before the protuberance recedes back into the volume of fluid.
