    摘要: A scanning probe microscope and method for operating the same are disclosed. The microscope includes a probe mount for attaching a probe, an electro-mechanical actuator, a probe position signal generator, an impulse signal generator and a servo. A probe tip is mounted on a first end of a cantilever arm, a second end of the cantilever arm being mounted on a mechanical vibrator that causes the second end to vibrate in response to a drive signal. The probe position signal generator generates a position signal indicative of a position of the probe relative to the second end of the cantilever arm. The impulse signal generator measures a quantity related to an impulse imparted to the probe tip by the interaction between the tip and the local characteristics of the sample. The servo operates the electro-mechanical actuator so as to maintain the measured quantity at a predetermined value.

    摘要: A puck is movable within a puck field of motion defined by a boundary. Arcuate springs connect the puck to the boundary. Each arcuate spring has a first end connected to the puck and a second end connected to the boundary, and applies a force to the puck that maintains the puck in a predetermined region of the puck field of motion when no external force is applied to the puck. In an embodiment, each arcuate spring includes a planar spiral member. The arcuate springs can also apply a force that dampens any oscillations in the puck position when the puck returns to the predetermined region in the puck field of motion. The puck can also include an electrode that is electrically connected to a point outside the puck field of motion by one of the arcuate springs.

    摘要: The pointing device has a moveable puck that moves over a surface in a puck field of motion. A position detector measures the puck position in the puck field of motion. In one embodiment, the puck includes a user sensor that detects an interaction between a user and the puck. A controller causes a cursor to move on a display in response to the puck moving in the puck field of motion when the user sensor senses the interaction between the user and the puck. The magnitude and direction of motion of the cursor is determined by the magnitude and direction of motion of the puck in the puck field of motion. In another embodiment, a restoring mechanism is provided that returns the puck to a predetermined area in the puck field of motion when the user releases the puck.

    摘要: An electrostatic actuator having a first member and a second member. The first member has a first opposed surface that includes an array of driven electrodes. The driven electrodes have a pitch pr. The second member has a second opposed surface and includes an array of drive electrodes. A support positions the first member adjacent the second member with the first opposed surface spaced apart from the second opposed surface by a spacing d. The ratio of the spacing and the pitch should be less than eight, and is preferably less than 2.25. The support permits the first member to move relative to the second member, or vice versa. A voltage source establishes a substantially alternating voltage pattern on the array of driven electrodes. An electrode control establishes a substantially alternating voltage pattern on the array of drive electrodes, and selectively imposes a local disruption on the substantially alternating voltage pattern on the array of drive electrodes to move the movable one of the first member and the second member relative to the other.
