  • Publication number: 20240079890
    Abstract: A battery charging system includes a charging rack comprising multiple receptacle, multiple battery assemblies. Each of the battery assemblies includes a housing having a handle, rechargeable battery cells disposed within the housing, and a mating feature protruding away from the housing, wherein the mating feature is configured to selectively connect the battery assembly with the receptacle of the charging rack and includes multiple ports electrically connected to the battery cells and configured receive power from the charging rack to charge the battery cells, and wherein the handle comprises a release button configured to selectively disengage the battery assembly from the receptacle of the charging rack.

  • Publication number: 20070238008
    Abstract: Aerogel-based thermal management systems and methods for vehicles incorporate aerogel materials to provide insulation and heat shielding. Various components of a vehicle must be protected from high temperatures, and conventional insulation undesirably adds weight and mass to the vehicle. Aerogel materials can be used for heat insulation and heat shielding while consuming minimal space and weight in the vehicle. The aerogel materials can be provided in monolithic or fiber-reinforced composite form, and can be enclosed in an encapsulating material such as a polymer, elastomer, or metal. The aerogel material is then attached on or near an automobile component.

  • Publication number: 20070163666
    Abstract: A lightweight and compact super-insulation system that is also capable of supporting a high level of compressive load is described. The system utilizes spacers to provide structural support and utilize controlled buckling of a thin protective outer skin supported by spacers to form strong catenary surfaces to protect insulation material underneath. The spacers may comprise an aerogel, or an aerogel may provide insulation separate from the spacer yet contained within the thin outer skin. The system will be useful for thermal management of variety of deep underwater structures such as pipe-in-pipe apparatus, risers or subsea trees for ultra-deep water oil-and-gas exploration.

  • Publication number: 20060264133
    Abstract: Many types of aerogel materials may be coated with polyorganosiloxane based coating compositions. Several such compositions, coating methods and additional ingredients are described. Such coatings add strength and increase the ability to use such aerogel materials in rugged environments. Various compositions include polyorganosiloxane components, crosslinkers, catalysts, optional fillers and other compounds.
