Decoupled, multiple stage positioning system

A split axis stage architecture is implemented as a multiple stage positioning system that is capable of vibrationally and thermally stable material transport at high speed and rates of acceleration. A split axis design decouples stage motion along two perpendicular axes lying in separate, parallel planes. A dimensionally stable substrate in the form of a granite, or other stone slab, or of ceramic material or cast iron, is used as the base for lower and upper stages. The substrate is precisely cut (“lapped”) such that its upper and lower stage surface portions are flat and parallel to each other.

Micro aerial vehicle

The purpose of this invention is to provide an ultra-miniature aircraft which is able to perform ‘Vertical Take-off and Landing (VTOL)’ and maintaining altitude when the vehicle is moving or when the horizontal velocity of a vehicle is at 0 by getting life only from a single rotor's rotation, and without using separate stabilizers such as a tail-rotor or a gyro. To fulfill the above purpose, this invention comprises: several blades in airfoil shape that are places in calculated angle and space; hubs that connect the blade to with a body of a vehicle; a rotor which gives lifting force with its spin; a spin-able axle which its vertical hem is bound to the hubs; a rotor drive that is needed to spin the rotor; a vehicle body that is placed right under the rotor in order to fly from the lift that is obtained by revolutions of the rotor; fixed-wings that are placed in certain angle and space around the outside of the vehicle body in order to reduce a reaction torque, which affects the body to turn the opposite direction of the rotor, from the rotor's movement; and a reaction-torque-counter-balancing-system on each of the above fixed-wings that offsets the reaction torque aggressively.

Process for plating a piezoelectric composite

A transducer having a ceramic element in which the ceramic is elevated above a polymer and a method of manufacturing the transducer. The transducer comprises a piezo-composite element comprising a ceramic element embedded in epoxy. In an array, the ceramic elements may be in the form of posts. The plurality of ceramic elements is slightly elevated above the polymer and in staggered arrangement with the polymer. The element is manufactured by first grinding the face of the composite and removing damaged ceramic by acid etching the ceramic. The epoxy is removed by plasma etching so that the ceramic is above the epoxy. The composite is sputter plated so that a maximum temperature that could damage the plating is not exceeded. The ceramic is then poled so that a maximum temperature that could damage the plating is not exceeded. Contacts are then attached to the plating adjacent the ceramic.

Specimen inspection stage implemented with processing stage coupling mechanism

A specimen inspection stage implemented with a processing stage coupling mechanism provides a capability to conduct with maximum efficiency post-processing specimen inspections on-board a processing platform. Heavy inspection equipment is mounted on a specimen inspection stage that is separate from a processing stage. In a preferred embodiment, the processing stage moves in response to an applied motive force and performs laser-based processing operations on a specimen. While laser processing is ongoing, the specimen inspection stage remains parked in its home position. When it is time for post-processing inspection, a stage coupling and decoupling mechanism couples together the specimen inspection stage and the processing stage, which transports the specimen inspection stage to and from the specimen position.
