Environmental Sensor
A controller for an environmental sensor provides digital environmental measurement values from analog environmental measurements performed by analog circuitry, the digital environmental measurement values lying in a global scale range. The controller subjects the global scale range to a subdivision into scale subranges that are proper subranges of the global scale range. The controller selects, among the scale subranges, one scale subrange in which an analog environmental measurement is to be performed, selects an offset information and a gain information that are associated with the selected scale subrange and that are indicative of an offset and a gain to be applied by the analog circuitry to perform an analog environmental measurement in the selected scale subrange, and to provide the offset information and the gain information to the analog circuitry.
Pressure sensor with increased absolute pressure detection
A pressure sensor includes a cylindrical case defining an inner space in communication with an outer space; a pressure detector provided in the inner space and configured to detect a gauge pressure of a target fluid; an atmospheric pressure detector configured to detect an atmospheric pressure; and an electronic component configured to calculate an absolute pressure of the target fluid on a basis of the gauge pressure and the atmospheric pressure. The absolute pressure is obtained without requiring airtightness of the case between the inner space and the outer space, and thus, there is no requirement for a seal member to be included between the inner space and the outer space.
Thickness-shear mode resonators
A pressure sensor that resonates in the thickness-shear mode (TSM) includes a center resonator structure, a first electrode positioned on a first side of the center resonator structure, and a first electrode flag. The first electrode flag forms a first electrically conductive path from the first electrode toward an outer portion of the center resonator structure. The first electrode flag extends at least partially over the first side of the center resonator structure. The first electrode flag also includes one or more first tab metals migrated thereinto from opposing sides of the first electrode flag.
Distributed electric air data module system
A distributed air data module system includes several air data systems and a control module communicatively connected to each air data system via a data channel. Each of the air data systems includes a sensor that is configured to sense an air data parameter and to provide a sensor output signal that is indicative of the sensed air data parameter, and a sensor analog-to-digital converter that produces a digital air data parameter signal that is representative of the sensor output signal. Each air data system has an associated air data system address code. The control module is configured to generate a selected air data system address code corresponding to a selected air data systems, receive the digital air data parameter signal associated with the selected air data system via the data channel, and transmit the digital air data parameter signal via an aircraft data bus.
Pressure sensor including an integrated position determining member
A pressure sensor includes a sensor element, an inner frame configured to receive at least a portion of the sensor element, and a housing configured to receive the inner frame therein. The inner frame is formed of a metal material and includes a printed circuit board assembly to be electrically connected to the sensor element. The housing is formed of a resin material.

Capacitive pressure sensors and other devices are disclosed. In an embodiment a semiconductor device includes a first electrode, a cavity over the first electrode and a second electrode including a suspended membrane over the cavity and electrically conductive anchor trenches laterally surrounding the cavity, wherein the anchor trenches include an inner anchor trench and an outer anchor trench, the outer anchor trench having rounded corners.
SENSOR FOR DETECTING PRESSURE, FILLING LEVEL, DENSITY, TEMPERATURE, MASS AND/OR FLOW RATE
A sensor for detecting pressure, filling level, density, temperature, mass and/or flow rate, wherein at least one central sensor component is coupled to a further component by nanowires and wherein the sensor component is stiffened, fixed and/or electrically contacted this way.
ARTICLES COMPRISING AN ELONGATED PRESSURE SENSITIVE COMPONENT
The invention relates to an article comprising an elongated pressure sensitive component in contact with a user. The pressure sensitive component forms a seal 7 between the user and the article when a minimum seal pressure is applied on the pressure sensitive component. The seal 7 comprises a signal pathway or an inductive loop indicative of a complete seal between user and article at the minimum seal pressure applied along the entire length of the pressure sensitive component.
TUBULAR SENSOR WITH DEFORMATION BODY
A flow-through pressure transducer comprising a cylindrical diaphragm positionable to allow fluid to flow therethrough which responds to variations in fluid pressure to generate an electrical signal proportional to such variations and which is incorporated in a housing for interconnecting with fluid delivery tubing. The diaphragm is made of relatively thin resilient metal, shaped to be a tube, elliptical in cross-section, with transducers, located on the elliptical major and minor axes which change their electrical state in response to movement of the diaphragm walls, and which are coupled in a bridge circuit for signal measurement. The housing is constructed for either gage or absolute fluid pressure measurements.
