Microelectromechanical Resonator And Method For Fabrication

US Patent:
7616077, Nov 10, 2009
Filed:
Mar 22, 2007
Appl. No.:
11/689567
Inventors:
Jonathan W. Wittwer - Albuquerque NM, US
Roy H. Olsson - Albuquerque NM, US
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
H03H 9/02
H03H 9/46
US Classification:
333186
Abstract:
A method is disclosed for the robust fabrication of a microelectromechanical (MEM) resonator. In this method, a pattern of holes is formed in the resonator mass with the position, size and number of holes in the pattern being optimized to minimize an uncertainty Δf in the resonant frequency fof the MEM resonator due to manufacturing process variations (e. g. edge bias). A number of different types of MEM resonators are disclosed which can be formed using this method, including capacitively transduced Lamé, wineglass and extensional resonators, and piezoelectric length-extensional resonators.

Microelectromechanical Resonator And Method For Fabrication

US Patent:
7652547, Jan 26, 2010
Filed:
Nov 12, 2008
Appl. No.:
12/269094
Inventors:
Jonathan W. Wittwer - Albuquerque NM, US
Roy H. Olsson - Albuquerque NM, US
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:

Softwall Mining Method And Device

US Patent:
6505892, Jan 14, 2003
Filed:
Jun 30, 2000
Appl. No.:
09/609568
Inventors:
Joseph Chryst Walker - Albany CA, 94710-1211
Randall D. Peterson - Sandy UT, 84092
Brandon H. Woolley - Provo UT, 84606
Jonathan Wayne Wittwer - Provo UT, 84604
Joel Brian Mundt - Provo UT, 84601
Jesse Tate Olson - Provo UT, 84604
Brian Douglas Gate - Provo UT, 84606
Nathan L. Baker - Lehi UT, 84043
K. S. Mortensen - Provo UT, 84602-4102
International Classification:
E21C 2740
US Classification:
299 32, 299 31, 299 33, 405145
Abstract:
A softwall mining method and device. Each of a plurality of mining devices comprise a supporting portion, an earth moving portion and a coupling mechanism for advancing the earth moving portion into a mining face, and for advancing the supporting portion toward the earth moving portion. Supporting portions of the devices are locked together to anchor movement of the earth moving portions, and earth moving portions of the devices are separately locked together to anchor the movement of the supporting portions.
