A gas turbine engine includes a liner positioned within a compressor section or a turbine section of the gas turbine engine and at least partially defining a core air flowpath through the gas turbine engine. The gas turbine engine also includes a casing at least partially enclosing the liner. Additionally, the gas turbine engine includes a pressure sensor assembly having a body, an extension member, and a pressure sensor. The pressure sensor is positioned at least partially within the body and the body is positioned at least partially on an outer side of the casing, the extension member extending from the body through a casing opening in the casing and towards a liner opening in the liner. The extension member defines a continuous sense cavity exposing the pressure sensor to the core air flowpath.

Standing desks, such as fixed work surfaces or height-adjustable desks or computer/workstation supports, provide relief from computer or other desk work that might otherwise force a user to remain seated. However, concerns about utilization and comfort are points of resistance to standing desks. A “smart” pressure sensing mat is provided that may provide additional cushioning and comfort as well as a source of data input for record keeping, usage verification, user identification, and control signals. Signals may be utilized to report data (e.g., utilization, user operations, functions, etc.) and/or control components (e.g., trigger a standing desk to rise for standing use or lower for seated use, activate lights, etc.).

An adaptive, any-fuel reciprocating engine using sensor feedback integration of high-speed optical sensors with real-time control loops to adaptively manage the electronic actuation schemes over a range of engine loads and fuels. The engine uses one or more optical sensors to collect specific types of gas property data via a spectroscopic technique to adaptively control various components within the engine.

The invention refers to a pressure-measuring device for converting a mechanical or hydraulic pressurization in a measuring signal and for forwarding the measuring signal to a remote evaluation unit. The invention distinguishes by a fastening device (1) for fastening the pressure-measuring device to a machine housing of a motor or a pump, a transmitter head (4) which is arranged on a measuring device head (3) of the pressure measuring device and which is to be connected to a light source via a first optical fiber (25), a receiver head (5) which is arranged on the measuring device head (3) of the pressure measuring device and which is arranged opposite to the transmitter head (4) to receive the light emitted by the transmitter head (4) via a light path in the measuring device head (3) and to be connected to the evaluation unit via a second optical fiber (26), and a measuring element (14), which in case of a mechanical or hydraulic pressure is displaceable on the measuring device head (3) into the light path between the transmitter head (4) and the receiver head (5).

An overpressure indicator is defined by a housing sized and configured for attachment within a compartment interior, such as an aircraft nacelle. A pressure sensing element disposed within the housing is coupled to an indicator element and is configured to detect a pressure differential between the interior and exterior of the compartment. The indicator element is caused to move in response to a predetermined change in pressure exceeding a threshold pressure differential. The indicator element includes a distal end that is moved to a position exterior of the housing and the compartment, providing a visual indication of an overpressure condition. A reset feature provided on the indicator can only be accessed by first opening the compartment in which the indicator has been mounted. A spring can be provided to assist in the triggering of the indicator member after the threshold pressure differential has been detected.
