Publication number: 20240127370Abstract: A dispatch optimization system and virtual power plant can be utilized and controlled in order to support the operations of a power distribution system. For example, upon determining an electrical need, the dispatch optimization system and/or virtual power plant may make an energy adjustment by allocating the energy adjustment among distributed energy resources of a fleet of distributed energy resources in order to achieve the energy adjustment. The dispatch optimization system and/or virtual power plant may determine the allocation among the distributed energy resources based on the economic costs and storage costs to use each distributed energy resource.Type: ApplicationFiled: August 30, 2023Publication date: April 18, 2024Applicant: Power Management Holdings (U.S.), Inc.Inventors: Michael K. Ruth, Duncan R. Brown, Andrew R. Gassner

Patent number: 9266722Abstract: Disclosed herein are MEMS resonator device designs and fabrication techniques that provide protection against electrostatic charge imbalances. In one aspect, a MEMS resonator device includes a substrate, an electrode including a first microstructure supported by the substrate, a resonant element including a second microstructure spaced from the first microstructure by a gap for resonant displacement of the second microstructure within the gap during operation, and a disabled shunt coupled to the electrode or the resonant element. The disabled shunt is disabled to enable the resonant displacement but otherwise configured to protect against damage from an electrostatic charge imbalance before the operation of the MEMS resonator device.Type: GrantFiled: December 31, 2013Date of Patent: February 23, 2016Assignee: Micrel, IncorporatedInventors: Barry D. Wissman, Andrew R. Brown, John R. Clark

Patent number: 8193869Abstract: A device has a resonator coupled to input and output nodes, the resonator being characterized by a transducer to drive the output node, and further characterized by a feedthrough capacitance such that portions of the input signal bypass the transducer to allow a spurious signal to reach the output node. The device includes a compensation capacitor coupled to the output node to define a compensation capacitance in accordance with the feedthrough capacitance. A phase inversion circuit is coupled to the compensation capacitance to generate a compensation signal and coupled to the output node such that the spurious signal is offset by the compensation signal. In some cases, a differential amplifier of the phase inversion circuit has the compensation capacitance in a feedback path to offset the feedthrough capacitance. In these and other cases, the compensation capacitance and the feedthrough capacitance may be unmatched to avoid overcompensation.Type: GrantFiled: February 3, 2010Date of Patent: June 5, 2012Assignee: Discera, Inc.Inventors: Andrew R. Brown, Wan-Thai Hsu, Kenneth R. Cioffi

Patent number: 7812680Abstract: Disclosed herein are devices and methods for generating a modulated signal with a MEMS resonator, or microresonator. A bias, or polarization, voltage for activating the MEMS resonator is determined by a control signal, or input voltage, indicative of information to be carried by the modulated signal. In some cases, the MEMS resonator may be driven by an oscillator circuit to facilitate operation of the MEMS resonator. The control signal may include an amplitude modulated voltage or a digital data stream such that output signals of the MEMS resonator or oscillator circuit may carry information via frequency modulation, such as frequency shift keying modulation.Type: GrantFiled: May 3, 2006Date of Patent: October 12, 2010Assignee: Discera, Inc.Inventors: Andrew R. Brown, Wan-Thai Hsu, Kenneth R. Cioffi, Didier Lacroix
