Patent number: 9322685Abstract: Systems and methods for measuring air speed which solve the problem of icing or blockage by creating an exterior surface on an aircraft that channels air and measures the pressure difference of the pressure through the airflow and the static pressure. This exterior surface cannot be blocked easily because air is always flowing when the aircraft is in motion, any external matter that could be on the exterior surface is readily visible, and the exterior surface can be heated to prevent icing. In addition, the exterior surface is made of a flexible material that is able to conform closely to the exterior shape of the aircraft. The preferred embodiments comprise microelectromechanical system pressure sensors placed under the air channels for measuring the pressure difference in each channel and an air speed processor for transforming the pressure differences into an air speed estimate.Type: GrantFiled: June 30, 2014Date of Patent: April 26, 2016Assignee: The Boeing CompanyInventor: Gary A.

Patent number: 9322731Abstract: Methods are directed to checking a pressure sensor comprising a reversibly deformable, in particular reversibly bendable measuring element which supplies a measurement signal having a value depending on the degree of deformation of said measuring element, to the effect of whether the pressure sensor withstands a required maximum pressure which is larger by a predeterminable factor than a nominal pressure for which the sensor is designed. The methods generally involve use of a reference pressure sensor, which is structurally identical to the pressure sensor to be checked, for generating a distance/pressure characteristic curve and for evaluating the critical pressure required for breaking the measuring element. The critical pressure can then be used to determine if a particular value of pressure is larger than the required maximum pressure that the pressure sensor to be checked is intended to withstand.Type: GrantFiled: December 5, 2011Date of Patent: April 26, 2016Assignee: ELMOS Semiconductor AGInventor: Peter Binkhoff

Patent number: 9322735Abstract: In some embodiments, at least one processor is employed to determine a boundary of a survey area. Data representative of the locations of measurement points adjacent to or outside of the survey area is received, as well as data representative of wind direction at the measurement points. The boundary of the survey area is determined according to the data representative of wind direction and a maximum detection distance value representative of an estimated maximum distance from a potential gas leak source at which a gas leak from the potential source can be detected. The boundary is determined such that if the potential gas leak source is located in the survey area and has a rate of leakage meeting a minimum leak rate condition, then an estimated probability of detection of the gas leak at one or more of the measurement points satisfies a probability condition.Type: GrantFiled: January 3, 2013Date of Patent: April 26, 2016Assignee: Picarro, Inc.Inventors: Sze Meng Tan, Chris W.
