  • 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: 10222143
    Abstract: Method for controlling heat transfer between two objects. In one embodiment, the method includes flowing a current through an electromagnet disposed about a container holding magnetorheological fluid to bias a first conductive element against a first end of the container and a second conductive element against a second end of the container to align particles in the magnetorheological fluid such that first conductive element is conductively coupled to the second conductive element; and reducing the current through an electromagnet such that the first conductive element is biased away from the first end of the container and the second conductive element is biased away from the second end of the container to break the alignment of the particles in the magnetorheological fluid such that the first conductive element is not conductively coupled to the second conductive element.

  • Publication number: 20180259381
    Abstract: An airflow sensor for a heat sink has a substantially flat base portion and a deformable upper portion electrically coupled to the base portion that contacts a conductive strip. As airflow increases, the deformable upper portion deforms and moves away from the source of airflow, which moves the point of contact between the deformable upper portion and the conductive strip farther away from the source of the airflow. The difference in the point of contact is measured, and is used to characterize the airflow sensor for different airflows. Data from the airflow sensor can then be logged during system operation. When needed, the data from the airflow sensor can be read from the log and converted to airflow using the airflow sensor characterization data. In this manner the airflow through a heat sink may be dynamically measured, allowing analysis and correlation between system events and airflow through the heat sink.

  • Patent number: 10045437
    Abstract: Embodiments of the disclosure relate to an apparatus and method for mitigation of warping of assembly components when subject to a thermal event. An interface unit with a complementary coefficient of thermal expansion is embodied in the assembly. The interface unit is configured to be received by a connector joined to the assembly substrate. The interface unit has a coefficient of thermal expansion (CTE) that complements the CTE of the assembly components in order to maintain the connector in alignment with the substrate and enable the connector to expand or contract with the substrate when subject to the thermal event.

  • Patent number: 9940920
    Abstract: Disclosed aspects relate to managing a set of devices using a set of acoustic emission data which indicates device-health of the set of devices. The set of devices is coupled with a set of acoustic emission sensors. Based on the set of acoustic emission data, a triggering event related to a first device of the set of devices is detected. Using the set of acoustic emission data, an event response which includes a first modification with respect to operation of the first device is determined. Establishment of the event response which includes the first modification with respect to operation of the first device is initiated.
