Title: Twin configuration for increased life time in touch mode electrostatic actuators
Inventor: CABUZ EUGEN L
IPC: G03B9/08
Filed: 1999-11-30
Granted: 2007-09-11
Abstract: An electrostatic actuator and drive configuration device for use in a system requiring a long term ON state operation. The device includes a first electrostatic actuator positioned to operate in the system requiring the long term ON state upon activation of a power supply. The device also includes a second electrostatic actuator positioned to operate in the system requiring the long term ON state upon activation of the power supply. A timer is connected to the power supply to alternately select the first or the second actuator for activation to drive the selected actuator to the ON state. The timer is controlled to select the first or second electrostatic actuator on an alternating basis to prevent either electrostactic actuator from remaining in the ON state for more than a predetermined time without the other actuator being selected. The electrostatic actuators may be configured in parallel or in series, depending upon the demands of the system. When the electrostatic actuators are switches, linear actuators or relays, they are normally connected side by side mechanically parallel. When the actuators are shutters, mirrors or valves, normal connection is in sequence end to end. When devices are selected to be in the ON condition, the selection should be such that each deviceis closed before the other is opened.

Abstract: A method is provided which is used to design soft contact lens via corneal topographic analysis. The topography of the cornea is matched to a corresponding topography of a soft contact lens. A  geometrical transformation which maps the corneal elevation onto the back surface of an unflexed soft contact lens is used to minimize errors induced by flexure of the lens. The mapping transformation takes into account the effects of flexure. As a result, the contact lens has a back surface with a curvature which matches the specific elevations of the cornea, while the front surface can be spherical or any desired symmetrical or asymmetrical shape.

Abstract: A laser cut stent for transluminal delivery has windows in its cylindrical wall, the windows giving the stent enhance flexibility during delivery along said lumen. A method of making such a sten t involves removing from the wall of a tube enough material to leave the tube wall penetrated in a multiplicity of separate cut lines, in a pattern which permits the tube to expand. The tube is then expanded and then a plurality of tube wall scrap portions are remove d from the tube wall between adjacent cut lines, thereby to introduce a plurality of spacings between adjacent stenting zones of the tube wall surface, these remaining after compression of the tube to a configuration to allow it to be advanced along a tortuous bodi ly lumen. Advantageously, the material of the tube is a shape memory alloy and the tube is for a self-expanding stent.

Abstract: A hog fuel board is made by placing a hog fuel mat including an ammonium chloride catalyst with flexible non-sticking layers on outside surfaces between screens in a preheated platen press and pressing the mat to preset stops and for a predetermined time and pressure to cause adhesives naturally present in the hog fuel to disperse throughout the board. The presence of ammonium chloride as a catalyst uniformly distributed through the hog fuel mat significantly lowers the temperature required at the heating press platens to form a board which also has improved properties. There is also described a hog fuel veneer board with a hog fuel mat sandwiched between veneer sheets and a lumber product with a hog fuel coating thereon. These additional products are both formed using the ammonium chloride catalyst to reduce press temperatures and create a product with improved properties, particularly, internal bond strength.
