Abstract
A microtome comprises a support assembly; an actuator, mounted to the support assembly; a pair of oscillating flexure assemblies, held by the support assembly and each of which being located on one side of the actuator and oscillated by the actuator; and a blade assembly, mounted to each of the oscillating flexure assemblies so as to move in a direction same as the oscillating flexure assemblies.
Claims24
A method for manufacturing a microtome, comprising:
- providing a support assembly;
- mounting an actuator to the support assembly;
- holding a pair of oscillating flexure assemblies by the support assembly, and locating each of the pair of oscillating flexure assemblies on one side of the actuator, and oscillating the pair of oscillating flexure assemblies using the actuator;
- and
- mounting a blade assembly to each of the oscillating flexure assemblies so as to move the blade assembly in a direction same as the oscillating flexure assemblies;
- wherein the method further comprises mounting a vibration control assembly to the support assembly for adjusting the actuator;
- wherein the vibration control assembly comprises:
- a sensor, measuring motions and forces of each of the oscillating flexure assemblies on both sides and generating a signal about the motions and the forces;
- a vibration controller, receiving the signal from the sensor, and estimating an unbalanced dynamic force/torque and determining a desired driving force that the actuator should generate based on a control algorithm in response to the signal;
- and
- a power amplifier, adjusting the actuator according to the desired driving force.
