Abstract: A device includes a sensor die, an electrical coupling, a substrate, and a housing unit. The sensor die is coupled to the substrate via the electrical coupling. The housing unit and the substrate are configured to house the sensor die and the electrical coupling. The housing unit comprises an opening that exposes the sensor die to an environment external to the housing unit. The housing unit may include a drainage configured to drain liquid, e.g., water, oil, etc., out from an interior environment of the housing unit to the environment external to the housing unit. In some embodiments the housing unit comprises a membrane barrier exposing the sensor die to an environment external to the housing unit while preventing liquid from the environment external to enter an interior environment of the housing unit. It is appreciated that in some embodiments, the membrane barrier may be porous and may be ePTFE.

Abstract: A device includes a die comprising a sensor. The device also includes a substrate that is coupled to the die via the electrical coupling. The device further includes a packaging container. The packaging container and the substrate form a housing for the die. The packaging container comprises an opening that exposes at least a portion of the die to an environment external to the housing. The exposed surfaces of the die, interior of the housing, the electrical coupling, and the substrate to the environment external to the housing through the opening are coated with a conformal film. The conformal film prevents liquid, e.g., water, gas, etc., contact to the exposed surfaces of the die, the electrical coupling and the substrate.

Abstract: A security system for a building comprises a pressure sensor and a computer system communicatively coupled with the pressure system. The pressure sensor coupled to a movable portion of a window in the building. The computer system is configured to: receive a first pressure measurement from the pressure sensor; compare the first pressure measurement to a reference pressure measurement; and based on the comparison, detect that the movable portion of the window has moved.

Abstract: A device includes a sensor die, an electrical coupling, a substrate, a liquid detection unit, and a housing unit. The sensor die is coupled to the substrate via the electrical coupling. The liquid detection unit electrically is coupled to the sensor die. The housing unit and the substrate are configured to house the sensor die, the liquid detection unit, and the electrical coupling. The housing unit comprises an opening that exposes the sensor die to an environment external to the housing unit. The liquid detection unit detects presence of liquid within an interior environment of the housing unit. In some embodiments, the device further includes a gel filled within the interior environment of the housing unit covering the sensor die and the substrate. The gel, e.g., silicone, fluoro silicone, etc., is configured to protect the sensor die, the electrical coupling, and the substrate from exposure to the liquid.

Abstract: A circuit board cooling system comprises a cooling unit comprising fans, pressures sensors that measure air pressure at their locations, and a sensor processing unit coupled with the pressure sensors. The cooling unit operates according to an operating configuration and generates air flow to cool a portion of a circuit board. The pressure sensors comprise a first pressure sensor located between the portion of the circuit board and the cooling unit; and a second pressure sensor located such that the portion of the circuit board is between the second pressure sensor and the cooling unit. A sensor processing unit is configured to: obtain the air pressure data measured by the plurality of pressure sensors; and adjust the operating configuration of the cooling unit based on a cooling specification and a comparison of the obtained air pressure data measured by the first pressure sensor and the second pressure sensor.

Abstract: A circuit board cooling system comprises a circuit board, a processor disposed on the circuit board, a cooling unit operating according to an operating configuration to generate air flow to cool a portion of the circuit board, a plurality of pressure sensors configured to measure air pressure data at their respective locations, and a sensor processing unit coupled with the plurality of pressure sensors. The plurality of pressure sensors comprises a first pressure sensor located between the processor and the cooling unit and a second pressure sensor located such that the processor is between the second pressure sensor and the cooling unit. The sensor processing unit: obtains the air pressure data measured by the plurality of pressure sensors; compares the obtained air pressure data to reference air pressure data for the operating configuration; and based on the comparison, determines that a disturbance to the air flow exists.
