Abstract: The method for mapping a mechanical property of a surface of a sample with a scanning force microscope comprises the steps of (a) scanning a fine tip in contact with the surface of the sample within a predetermined scan area, the fine tip being supported on an end of a cantilever beam, (b) applying a loading force on the surface of the sample by the fine tip, (c) using a constant frequency sine wave to oscillate the cantilever beam relative to the surface of the sample, (d) measuring a detector response of the fine tip at the end of the cantilever beam, (e) determining an amplitude of the detector response and a change in phase angle of the detector response relative to the sine wave used to oscillate the cantilever beam, and (f) relating the amplitude and the change in phase angle to a property of the surface of the sample. A feedback system is utilized which regulates the total force imposed by the fine tip onto the surface of the sample so that the amplitude of the detector response is maintained constant.

Abstract: A golf ball teeing device and associated cage for catching a golf ball it from the teeing device includes a manually actuated trough for teeing one ball after another in succession on a tee to be hit. A cage catches the balls that are hit, and a ball return mechanism returns the balls to the teeing device. The returned balls line up in a row in alignment with a ball entrance of the teeing device. One ball at a time is fed to a ball cavity in the teeing device. The person using the teeing device actuates an elongate trough that is associated with the ball cavity to pivot downwardly allowing the ball in the ball cavity to roll down the trough. A guide on the distal end of the trough sets the ball on a tee, and the trough can then be returned to its ready position in which a new ball is fed to the ball cavity. After hitting the teed ball, the user again actuates the trough to tee the next ball that is to be hit.
