  • Patent number: 10283999
    Abstract: An information handling system (IHS) includes a base station that has a transmitter coil to generate a magnetic field for charging a portable power source of a battery-powered electronic device. A receiver coil magnetically receives power from the transmitter coil of the base station. A power control module connected to the portable power source and the receiver coil charges the portable power source with the received power. A flexible ferrite shield is positioned on a side of the receiver coil opposite to the transmitter coil to shield the IHS electronics. A pneumatic diaphragm is formed by a portion of the flexible ferrite shield that is positioned for oscillating movement into a center cavity of the receiver coil. A diaphragm actuator is attached to the pneumatic diagram and is responsive to a triggering signal to oscillate the pneumatic diaphragm to disperse thermal energy that is generated by the receiver coil.

  • Patent number: 10125748
    Abstract: A thermal actuator for a rotating shaft shutdown seal that has a piston with a portion of its axial length enclosed within a chamber shell with a material that expands upon a rise in temperature. The portion of the actual length of the piston within the chamber has at least two different diameters with the larger diameter leading in the direction of travel of the piston. Upon a rise in temperature, expansion of the material surrounding the piston within the chamber creates a force on the piston in the desired direction of travel. Below a preselected temperature the piston is positively locked with a passive release when the preselected temperature is reached.
