    摘要: Altitude determining circuitry for use in a User Equipment (UE) of a wireless communication network is provided. The circuitry comprises a receiver to receive at least one pressure parameter representative of a plurality of indoors pressure measurements from a respective plurality of indoors pressure measurement units located inside a building at different altitudes. The altitude determining circuitry also has processing circuitry to receive from a pressure sensor in the User Equipment a local pressure measurement at the UE and the processor determines an indoors altitude of the UE using the at least one pressure parameter and the UE local pressure. An integrated circuit for a Global Navigate Satellite System comprising the altitude determining circuitry and an indoors pressure measurement unit having a sensor for making a pressure measurement and a transmitter for transmitting the pressure measurement to the UE or to a further indoors pressure measurement unit are also provided.

    摘要: A pressure gauge includes: an outer container defining an outer chamber set to a reference pressure (Pr); an inner container disposed in the outer container; and a tube setting the inside of a first inner chamber of the inner container to a measurement pressure (Px). The inner container includes: a cylindrical rigid wall portion; first and second pressure receiving plates that displace due to a differential pressure between the reference pressure and the measurement pressure; a bellows partitioning the inner container into the first inner chamber and a second inner chamber; and a pressure detection element disposed in the second inner chamber and detecting the measurement pressure based on the displacements of the first and the second pressure receiving plates. The outer chamber and the second inner chamber are set to the reference pressure of a high vacuum that is lower than a lower limit of the measurement pressure.

    摘要: A differential pressure sensor chip (2) includes: first and second pressure introduction holes (21_1 and 21_2); first and second diaphragms (23_1 and 23_2) formed to cover the first and second pressure introduction holes; first and second depressions (24_1 and 24_2) each in a form of a depression respectively provided to face the first and second pressure introduction holes with the first and second diaphragms interposed therebetween; a first communication channel (25) that makes a chamber between the first depression and the first diaphragm and a chamber between the second depression and the second diaphragm communicate to each other; a pressure-transmission-material introduction passage (26) an end of which is an opening and another end of which is joined to the first communication channel; a pressure transmission material (27) that fills the first communication channel, the two chambers, and the pressure-transmission-material introduction passage; and a sealing member (7) formed of a metal formed to seal a depression on a metal layer (9) formed on a surface of the opening of the pressure-transmission-material introduction passage.

    摘要: In one aspect, a pressure sensor for detecting a pressure differential between first and second fluid sources may include sensor body defining a cavity and a seal plate slidably positioned within the cavity. The seal plate may define first and second chambers within the cavity, which may respectively be in fluid communication with the first and second fluid sources. The sensor may also include a sensing element configured to detect a position of the seal plate relative to the sensor body, which may be indicative of the pressure differential between the first and second fluid sources. The sensor may further include a first spring positioned within the first chamber and compressed between a first side of the seal plate and the sensing element. Additionally, the sensor may include a second spring positioned within the second chamber and compressed between a second side of the seal plate and the sensor body.

    摘要: A system to detect a pressure difference between the interior of a cabin of an aircraft and the exterior of the aircraft. The system includes a window arrangement having a first windowpane with a first surface and an opposite second surface and is adapted to be mounted in an aircraft such that the first surface of the first windowpane faces the exterior of the aircraft and is subjected to ambient outside atmospheric pressure and the second surface faces the cabin interior, and a pressure sensor including a first pressure port. The first windowpane includes a first air passage opening extending between the first and second surfaces of the first windowpane, and the pressure sensor is sealingly connected to the first air passage opening such that the first pressure port of the pressure sensor is subjected to pressure acting on the first surface of the first windowpane.
