  • Publication number: 20210133952
    Abstract: An electronics system may include a substrate, an electronic device bonded to the substrate, a plurality of photoluminescent particles disposed on the electronic device, an illuminator, a sensor, and a control module. The illuminator can illuminate the electronic device. The sensor can capture a first set of positions of the photoluminescent particles on the electronic device when the electronic device is not operating under a load and a second set of positions of the photoluminescent particles when the electronic device is operating under a load. The control module can determine thermomechanical stress on the electronic device based at least in part on a difference between the first set of positions and the second set of positions.

  • Patent number: 10479246
    Abstract: Seats in vehicles may include a seat cushion having a seating surface, a vibration isolation structure and a foam structure, with the seating surface configured to support an occupant. The seat cushion may include either a seat bottom or a seat back, with the vibration isolation structure configured to evenly distribute forces exerted by the occupant. The vibration isolation structure may include a plurality of individual lattice blocks. The plurality of individual lattice blocks may occupy a pattern based on a spatial weight distribution of an average-sized occupant or a pattern based on a spatial weight distribution tailored for a specific occupant. The plurality of individual lattice blocks may cooperate to provide the even pressure distribution against forces exerted by the occupant. The vibration isolation structure may isolate vibration in a range from about 0.5 Hz to about 5.0 Hz.
