  • Thermal management device for use on electronics in a transportation vehicle
    Patent number: 10932395
    Abstract: A thermal management device for dissipating heat from an electrical component includes a volume of working fluid configured to change from a liquid state to a vapor state in response to being heated by the electrical component. The thermal management device also includes a working fluid chamber configured to move the working fluid. The working fluid chamber includes an impermeable outer portion and a porous inner portion integrally formed with and connected to the impermeable outer portion. The inner portion is configured to move the working fluid when in the liquid state toward the electrical component. The impermeable outer portion is made of a first material and the porous inner portion is made of a second material. The first material is different from the second material.

  • ENERGY ABSORBER SYSTEM AND VEHICLE
    Publication number: 20150323034
    Abstract: An energy absorber system for a vehicle includes a first panel and a second panel spaced apart from the first panel to define a cavity therebetween, wherein the second panel defines an aperture therethrough. The energy absorber system also includes an energy absorber disposed within the cavity and attached to the first panel. The energy absorber system further includes a plurality of fasteners, and a plate mounted to the second plate by the plurality of fasteners so as to cover the aperture. A vehicle including the energy absorber system is also disclosed.
