Patent number: 8661899Abstract: An apparatus is described that includes a substrate having a first plate and a second plate. The first plate and the second plate collectively have a first mode when excited by a drive signal and have a second mode when excited by a gyroscopic effect. The first and second plates each include a temperature-compensated stack having first and third layers that have a stiffness that increases with increasing temperature over a temperature range with a second layer between the first and third layers, where the second layer is formed from a different material than the first and third layers.Type: GrantFiled: March 1, 2011Date of Patent: March 4, 2014Assignee: Sand9, Inc.Inventors: Guiti Zolfagharkhani, Jan H.

Publication number: 20130200752Abstract: Mechanical resonating structures and related methods are described. The mechanical resonating structures may provide improved efficiency over conventional resonating structures. Some of the structures have lengths and widths and are designed to vibrate in a direction approximately parallel to either the length or width. They may have boundaries bounding the length and width dimensions, which may substantially align with nodes or anti-nodes of vibration.Type: ApplicationFiled: February 7, 2012Publication date: August 8, 2013Applicant: Sand9, Inc.Inventors: Jan H.

Publication number: 20120013410Abstract: Methods and apparatus for calibration and temperature compensation of oscillators having mechanical resonators are described. The method(s) may involve measuring the frequency of the oscillator at multiple discrete temperatures and adjusting compensation circuitry of the oscillator at the various temperatures. The compensation circuitry may include multiple programmable elements which may independently adjust the frequency behavior of the oscillator at a respective temperature. Thus, adjustment of the frequency behavior of the oscillator at one temperature may not alter the frequency behavior at a second temperature.Type: ApplicationFiled: July 13, 2011Publication date: January 19, 2012Applicant: Sand9, Inc.Inventors: Reimund Rebel, Jan H.
