  • Patent number: 10309735
    Abstract: An airflow sensor for a heat sink has a first portion having a first electrical point of contact, a second portion have a second electrical point of contact, and a deformable portion made of an electroactive material electrically coupled to the first and second portions. The deformable portion has first electrical properties measured between the first and second electrical points of contact when there is no airflow and the deformable portion is in a first position, and has second electrical properties different than the first electrical properties when a source of airflow blows air against the deformable portion, thereby causing the deformable portion to extend to a second position farther away from the source of airflow than the first position. The airflow sensor can be incorporated into a heat sink for an electronic component.

  • Patent number: 10309810
    Abstract: In order to solve a problem occurring in a capacitance type pressure sensor adapted to measure absolute pressure, and thereby reduce error, a pressure type flowmeter includes a fluid resistance part in a flow path through which fluid flows and measures a flow rate by detecting the upstream and downstream pressures of the fluid resistance part. Respective pressure sensors for detecting the upstream and downstream pressures are configured to be gauge pressure sensors. Each of the gauge pressure sensors is a capacitance type pressure sensor adapted to measure gauge pressure by detecting a change in the capacitance between a diaphragm displaceable by pressure and a fixed electrode and has a main body part that supports the fixed electrode and the diaphragm and forms a space between them. Further, the internal space is adapted to communicatively connect to the outside through a communicative connection part.

  • Patent number: 10281309
    Abstract: A gas flow meter comprises a meter body, a tube, and a sensing unit. The sensing unit includes a base connected with one end of the tube; a speed transducer penetrating the base; a temperature transducer penetrating the base; a temperature compensator penetrating the base; and a microcontroller accommodated inside the meter body. The microcontroller is electrically connected with the speed transducer, the temperature transducer and the temperature compensator. The temperature transducer only functions to detect the temperature of the surrounding gas. The temperature compensator only functions to compensate the speed transducer for the temperature drop thereof. Each of them functions independently. Once the temperature of the speed transducer lowers, the temperature compensator directly compensates for the temperature drop, whereby the statistic error value is effectively decreased.
