    摘要: A heat pipe is provided for cooling an electronic component of a printed circuit board. The heat pipe includes a tube having an inner diameter surface defining a bore, with the tube having first and second ends along the bore. The heat pipe further includes a sorbent material coated onto the inner diameter surface of the tube, a first liquid contained within the bore, and a second liquid adsorbed by the sorbent material. The second liquid has a second boiling temperature that is higher than a first boiling temperature of the first liquid. The first liquid vaporizes into a first vapor, in response to the tube receiving heat from the electronic component and the first liquid reaching the first boiling temperature. The second liquid is desorbed from the sorbent material and vaporizes into a second vapor in response to the second liquid reaching the second boiling temperature.

    摘要: A climate control device includes a radiant heater for radiating heat and a porous material attached to the radiant heater. The porous material desorbs a plurality of water molecules, in response to the porous material receiving heat from the radiant heater and raising a temperature of the water molecules in the porous material to a boiling temperature threshold. The porous material adsorbs the water molecules in response to the temperature of the water molecules falling below the boiling temperature threshold.

    摘要: A system for determining a trigger amplitude indicating a precursor to a material fracture in a specimen under test includes a microphone converting acoustic emission emitted by the specimen under test into electrical signals. A load is exerted upon the specimen under test and the acoustic emission are emitted when the load causes the specimen under test to undergo deformation prior to the material fracture. A control module is in electrical communication with the microphone and executes instructions to monitor the electrical signals generated by the microphone and filter the electrical signals generated by the microphone. The control module converts the electrical signals generated by the microphone into individual frequency components based on a fast Fourier Transform (FFT). The individual frequency components each include a peak intensity. The control module determines the trigger amplitude based on the peak intensity of the individual frequency components of the FFT.

    摘要: A non-integrated monitoring device and method for monitoring a subject vehicle includes monitoring, via a non-integrated sensor, a physical parameter being emitted from the subject vehicle. The physical parameter being emitted from the subject vehicle is analyzed to determine a dynamic signature for the subject vehicle. A baseline signature for the subject vehicle is obtained, and compared to the dynamic signature for the subject vehicle. Occurrence of a fault in a subsystem of the subject vehicle is detected based upon the comparing of the baseline signature for the subject vehicle and the dynamic signature for the subject vehicle, and the occurrence of the fault is communicated to an operator of the subject vehicle.

    摘要: A heat dissipation device for an electronics cooling system having an electronic component includes a housing that defines a chamber. The device further includes a first liquid, which is contained within the chamber and has a first boiling temperature. The device further includes a sorbent material immersed within the first liquid. The device further includes a second liquid, which is adsorbed by the sorbent material and has a second boiling temperature that is above the first boiling temperature. The first liquid vaporizes into a first vapor, in response to the first liquid reaching the first boiling temperature. The second liquid is desorbed from the sorbent material, in response to the second liquid and the sorbent material reaching a desorption temperature that is below the second boiling temperature. The second liquid vaporizes into a second vapor, in response to the second liquid reaching the second boiling temperature.

    摘要: Systems, apparatuses, and methods are described that combine a sorbent containing a flame retardant with a substrate, which is capable of responding to temperature increases to prevent, suppress, delay the spread of, or otherwise mitigate a proximal thermal event. A flame retardant system has a flame retardant material that is incorporated into a matrical sorbent material, which is incorporated into a substrate. The matrical sorbent material is configured to release the flame retardant material upon exposure to an elevated temperature, e.g., a temperature that is greater than 300° C. in one embodiment.
