Abstract: A pressure distribution measurement system for measuring a pressure distribution on a measurement object. A flexible sheet-form pressure detection member includes a plurality of pressure passages extending in parallel and a pressure detection hole opened in each of the pressure passages is affixed to a surface of an outer plate of a main wing W of an airplane. Each of the pressure passages is connected to a pressure measurement device via a pressure pipeline. Because the pressure detection hole is opened in the pressure detection member, that is, the pressure detection hole is not required to be opened in the outer plate of the main wing, the outer plate is not damaged. Further, because the flexible sheet-form pressure detection member conforms well to the three dimensionally curved surface of the outer plate and has a small thickness, the airflow is hardly disturbed at all, thereby enhancing pressure distribution measurement accuracy.

Abstract: Two heat generating resistors are formed on a substrate in the upstream side with respect to an air flow direction and two other heat generating resistors are formed in the downstream side. A thermometer resistor for detecting a temperature in the intake manifold is formed on the substrate. A bridge circuit is formed of the heat generating resistors. A temperature of the four heat generating resistors is controlled to be at a predetermined temperature by balancing a bridge circuit constituted of the thermometer resistor or the like with a differential amplifier and a transistor. When air flows, electric potentials of the intermediate terminals in the bridge circuit change. A flow quantity and a flow direction of the air are calculated by detecting the electric potential difference.

Abstract: In a flow sensor, detecting elements are provided at a sub-passage. A sub-passage wall contains a hole to drain accumulated liquid. A protrusion arranged close to the hole on an external surface generates dynamic pressure on the opening in response to external flow. Alternatively, a protrusion upstream from the hole on the inner wall surface produces a separation flow area for separating the flow from the internal surface near the hole, whereby pressure in the separation area is reduced and almost the same pressure differences on the internal and external surfaces openings result. This reduces leakage from the hole and changes in the distribution flow in the sub-passage between cases where the hole is blocked and not blocked, thus minimizing flow measurement errors. Structure may be provided close to the external surface hole opening to prevent a liquid film or drop from being formed on the opening by surface tension.

Abstract: The present invention provides a probe having a resistance that varies with temperature and is operable to determine the quantity of a fluid, such as hydrogen, in a storage tank, such as a cryogenic storage tank.

The probe can be configured to account for the geometry of the storage tank thereby providing a linearized signal indicative of the quantity of fluid in the storage tank.

The accelerometer and rate sensor package is mounted directly on or within a gravity gradiometer instrument (GGI).

Thus, outputs from the GGI can be corrected more effectively using the sensor assembly's outputs.
