Patent number: 9257247Abstract: A motion-sensitive low-G MEMS acceleration switch, which is a MEMS switch that closes at low-g acceleration (e.g., sensitive to no more than 10 Gs), is proposed. Specifically, the low-G MEMS acceleration switch has a base, a sensor wafer with one or more proofmasses, an open circuit that includes two fixed electrodes, and a contact plate. During acceleration, one or more of the proofmasses move towards the base and connects the two fixed electrodes together, resulting in a closing of the circuit that detects the acceleration. Sensitivity to low-G acceleration is achieved by proper dimensioning of the proofmasses and one or more springs used to support the proofmasses in the switch.Type: GrantFiled: June 9, 2014Date of Patent: February 9, 2016Assignee: Meggitt (Orange County), Inc.Inventor: Tom Kwa

Patent number: 8746045Abstract: Methods and systems are disclosed for using time domain reflectometry to determine the identity of a fluid in a vessel, and to determine whether the quality of a fluid in a vessel is within acceptable parameters. Methods include identifying a fluid by comparing a derived characteristic of a fluid to a reference characteristic, determining the quality of a fluid by determining if a derived characteristic is within an acceptable quality range, monitoring a fluid for a dynamic change in quality or state, and identifying a fluid by comparing a transition reflection waveform to a reference signature transition. The methods are implemented in systems for identifying a fluid layer in a vessel, such as fuel, free liquid water or ice, detecting misfueling or fuel contamination, and detecting fluid state changes, such as the formation of ice.Type: GrantFiled: April 14, 2011Date of Patent: June 10, 2014Assignee: Meggitt (Orange County), Inc.Inventors: Carlos E.
