  • Patent number: 11897379
    Abstract: A vehicle seat can be configured to provide support to a vehicle occupant in conditions when lateral acceleration is experienced. Shape memory material members can be operatively positioned with respect to a seat portion of the vehicle seat. The shape memory material members can be selectively activated by an activation input. When activated, the shape memory material members can engage a seat pan so as to cause the seat pan to tilt in a respective lateral direction. As a result, a seat cushion supported by the seat pan can also tilt in the respective lateral direction. The seat cushion can be tilted in a lateral direction that is opposite to the direction of the lateral acceleration. Thus, the effects of lateral acceleration felt by a seat occupant can be reduced. The shape memory material members can be selectively activated based on vehicle speed, steering angle, and/or lateral acceleration.

  • Patent number: 11785743
    Abstract: A thin, single-layer thermally conductive jacket surrounds a PCA. One or more living springs integrated in the jacket exert compressive force on PCA components where cooling is desired. The compressive force creates and maintains a thermal contact though which heat is conducted out of the PCA components and into the jacket. The jacket conducts the heat (either directly or indirectly) to a liquid-cooled cold plate configured as a cooling frame surrounding one or more of the jacketed PCAs. The jacket, optionally through intermediate thermal transfer devices such as heat spreaders or heat pipes, transfers heat from components on the PCA to the cooling frame. Liquid flowing through the cooling frame's internal channels convects the heat out of the electronic device. Turbulence encouraged by turbulence enhancing artifacts including bends and shape-changes along the internal channels increases the efficiency of the convection.

  • Patent number: 11512711
    Abstract: A centrifugal fan frame body structure includes a lower case body and a cover body. The lower case body has a bottom section and an outer wall section. The outer wall section is formed with a wind outlet. The cover body and the lower case body are correspondingly mated with each other to form a space. In the space, the lower case body and the cover body define therebetween a first height. The lower case body and the cover body define therebetween a second height at the wind outlet. The second height is larger than the first height. The height of the wind outlet is enlarged, whereby the wind outlet will not be blocked by the cooperative heat dissipation component (module) so that the flow field efficiency is enhanced and the noise is lowered.

  • Patent number: 11452231
    Abstract: Various types of electronic devices may be mounted in a chassis in order to facilitate interfacing with the devices, containing the devices, provide cooling systems which may remove heat from the electronic devices, etc. Delivering adequate cooling air flow to each electronic device in a chassis may be an important issue for the proper functioning, lifetime, or other characteristics of electronic devices contained in a chassis. Some electronic devices may be particularly challenging to cool due to various design characteristics. Other electronic devices may have other requirements that are not well served by existing chassis designs. For example, some electronic devices may benefit from additional electrical and/or thermal connections. Embodiments presented herein describe a novel design for a modular card cage accessory that may be configured to modify air flow and/or to meet particular requirements of an electronic device in a chassis, among various possibilities.
