Patent number: 8330323Abstract: A source signal is converted into a time-variant temperature field with transduction into mechanical motion. In one embodiment, the conversion of a source signal into the time-variant temperature field is provided by utilizing a micro-fabricated fast response, bolometer-type radio frequency power meter. A resonant-type micromechanical thermal actuator may be utilized for temperature read-out and demodulation.Type: GrantFiled: November 9, 2011Date of Patent: December 11, 2012Assignees: Cornell Research Foundation, Inc., Naval Research LaboratoryInventors: Maxim Zalalutdinov, Robert B. Reichenbach, Keith Aubin, Brian H. Houston, Jeevak M. Parpia, Harold G. Craighead

Patent number: 8049580Abstract: An array of micromechanical oscillators have different resonant frequencies based on their geometries. In one embodiment, a micromechanical oscillator has a resonant frequency defined by an effective spring constant that is modified by application of heat. In one embodiment, the oscillator is disc of material supported by a pillar of much smaller diameter than the disc. The periphery of the disc is heated to modify the resonant frequency (or equivalently the spring constant or stiffness) of the disc. Continuous control of the output phase and frequency may be achieved when the oscillator becomes synchronized with an imposed sinusoidal force of close frequency. The oscillator frequency can be detuned to produce an easily controlled phase differential between the injected signal and the oscillator feedback. A phased array radar may be produced using independent phase controllable oscillators.Type: GrantFiled: November 2, 2010Date of Patent: November 1, 2011Assignee: Cornell Research Foundation, Inc.Inventors: Robert B.

Patent number: 7812502Abstract: A micromechanical resonator is formed on a substrate. The resonator has a partial spherical shell clamped on an outside portion of the shell to the substrate. In other embodiments, a flat disc or other shape may be used. Movement is induced in a selected portion of the disc, inducing easily detectible out-of-plane motion. A laser is used in one embodiment to heat the selected portion of the disc and induce the motion. The motion may be detected by capacitive or interferometric techniques.Type: GrantFiled: February 20, 2006Date of Patent: October 12, 2010Assignees: Cornell Research Foundation, Inc., Navel Research LaboratoryInventors: Maxim Zalalutdinov, Robert B.

Patent number: 7358822Abstract: The temperature of a remote portion of device having a microelectromechanical oscillator is modulated to create oscillation of the oscillators. In one embodiment, a localized heat source is placed on a device layer of a multilayered stack, consisting of device, sacrificial and substrate layers. The localized heat source may be a laser beam in one embodiment. The oscillator is supported by the device layer and may be formed in the device layer in various embodiments. The oscillator may be spaced apart from the localized heat source.Type: GrantFiled: January 20, 2006Date of Patent: April 15, 2008Assignee: Cornell Research Foundation, Inc.Inventors: Keith Aubin, Bojan (Rob) Ilic, Maxim Zalalutdinov, Robert B.
