Abstract: Methods and apparatuses for indicating the presence of a threshold directional differential pressure between separated adjacent spaces. An inclined conduit contains at least one movable element that indicates whether the pressure difference between the two spaces is at least as high as a threshold pressure difference. The apparatus may provide a compact arrangement while allowing the movable element to have a suitable travel path length within the conduit.

Abstract: An encapsulated shock absorber of an aircraft undercarriage includes a sliding rod slidably mounted in a leg strut of the undercarriage and an inner cylinder extending inside the strut. The inner cylinder is fastened to the strut via a top end, and the rod slides around the inner cylinder. The inner cylinder is terminated inside the sliding rod by a diaphragm that defines an oil chamber in the shock absorber and inside the sliding rod. A mixed oil/gas chamber is located in the inner cylinder, and an expansion chamber extends between the sliding rod and the inner cylinder. A hole being made in the inner cylinder in register with the expansion chamber is connected by a pipe to a pressure sensor situated outside the strut. The pipe extends inside the inner cylinder from the hole to the top end of the inner cylinder.

Abstract: A method for controlling an actuatable safety device (110) for helping to protect a vehicle occupant includes sensing left-front and right-front pressure values via a pressure tube sensor (18). The method also includes executing pressure tube metrics that evaluate the left-front and right-front pressure values and selecting switched crash thresholds in response to the pressure tube metrics. The method also includes sensing vehicle acceleration parameters (99) and executing one or more crash metrics that evaluate the vehicle acceleration parameters to determine whether the switched crash thresholds are exceeded. The method further includes controlling deployment of the actuatable safety device (110) in response to determining that the switched crash thresholds are exceeded. A vehicle safety system (100) implements the method.

Abstract: A pressure transmitter is disclosed. A pressure measuring portion pressurized by a target fluid that is a target of a pressure measurement and a reference pressure measuring portion pressurized by an external fluid outside a pipe are provided. In addition, a part of the pressure measuring portion that is pressurized by the target fluid and a part of the reference pressure measuring portion that is pressurized by the external fluid are provided inside one thermally conductive member. Accordingly, at the portion pressurized by the target fluid and at the portion pressurized by the external fluid, a difference in temperature between the pressure measuring portion and the reference pressure measuring portion may be insignificantly small. As a result, an accuracy of an operation of correcting an error that may be generated by thermal expansion of the medium fluid in the pressure measuring portion can be improved.

Abstract: A micromechanical component for a pressure and inertial sensor device. The component includes a substrate having an upper substrate surface; a diaphragm having an inner diaphragm side oriented towards the upper substrate surface and an outer diaphragm side pointing away from the upper substrate surface, the inner diaphragm side bordering on an inner volume, in which a reference pressure is enclosed, and the diaphragm being able to be warped using a pressure difference between a pressure prevailing on its outer diaphragm side and the reference pressure; and a seismic mass situated in the inner volume, a sensor electrode, which projects out on the inner diaphragm side and extends into the inner volume, being displaceable with respect to the substrate due to a warping of the diaphragm. A pressure and inertial sensor device, and a method of manufacturing a micromechanical component for a pressure and inertial sensor device, are also described.

Abstract: A backflow preventer (10, 128) includes a body (12, 130). The body includes an inlet port (14, 132) and an outlet port (16, 134). A central cylindrical bore (26, 144) extends in the body and axially between the inlet port and the outlet port. A first check valve (40, 152) and a second check valve (42, 156) are removably mounted in the bore through an insertion opening (38, 150). A removable plug (94, 95, 158) is positionable in the insertion opening to hold the check valves within the bore. Some exemplary arrangements include a translucent body to facilitate visual observation of proper check valve operation and testing of the backflow preventer.

Abstract: An apparatus includes a dissolvable gauge cutter, a temperature sensor, and a pressure sensor. The dissolvable gauge cutter is made of a dissolvable alloy. The dissolvable gauge cutter is configured to be disposed within and travel through a tubular installed within a wellbore. The dissolvable gauge cutter is configured to dislodge solids from an inner wall of the tubular as the dissolvable gauge cutter travels through the tubular down to a specified depth within the wellbore. The dissolvable gauge cutter is configured to completely dissolve after reaching the specified depth. The temperature is configured to measure a temperature of a surrounding fluid as the dissolvable gauge cutter travels downhole through the tubular to the specified depth. The pressure sensor is configured to measure a pressure of the surrounding fluid as the dissolvable gauge cutter travels downhole through the tubular to the specified depth.

Abstract: A micromechanical sensor system with a micromechanical structure and with a control and sensing device. The micromechanical sensor system is configured for repeatedly generating and outputting sensor measured values at a specified output data rate, and at an output of the micromechanical sensor system. During a first part of an output time interval, the control and sensing device realizes an energy-saving operating mode, and, for generating the sensor measured values, the micromechanical structure is controlled and/or its position or configuration is sensed by the control and sensing device during the output time interval. Temporally after the first part of the output time interval and as part of the measurement time interval, during a preparation or downtime interval, the generation of the sensor measured values is prepared. The duration of the preparation or downtime interval and/or the first part of the output time interval is changeable or adaptable.
