  • Patent number: 10240823
    Abstract: An air conditioning system that includes desiccant compartments for holding a desiccant; a heat exchanger, a blower and a vessel. The heat exchanger can be filled with a heat transfer medium, while the blower blows ambient air by the heat exchanger such that the blown air is cooled and the heat exchanger is warmed such that thermal energy increases and is transferred from the air to the heat transfer medium causing the heat transfer medium to turn into vapor. The vapor is then diffused to one of the desiccant compartments such that the vapor is adsorbed onto the desiccant creating a mixture. Then an energy source is applied to the mixture such that the vapor and desiccant are separated. The separated vapor is transported to the vessel where it is condensed and then sent back to the heat exchanger, such that the system is able to be continuously operating.

  • Publication number: 20120117997
    Abstract: The present invention is a cooling sleeve, which has a sheath and a gas cartridge. The sheath is able to slip over a user's clothed arm), and includes a chamber disposed within the sheath. The chamber is able to thermally communicate with the user's arm. The gas cartridge supplies cooling gases to the chamber such that the user's arm is cooled, whereby the user's core temperature is cooled.

  • Publication number: 20100280331
    Abstract: Non-invasive methods and devices are disclosed to derive estimates of body Core Temperature from external sensors that provide electrocardiograph (ECG) data, and Mean Skin Temperature data. The ECG and Mean Skin Temperature are input to a model that provides estimates of Core Temperature temperature. The model is derived regressively from ECG, Mean Skin Temperature and Core Temperature data obtained from a number of test subjects. A monitoring device may be used, for example, to trigger an alarm, display Core Temperature data to the device wearer or to a remote monitoring station, or to activate an emergency temperature control system or device.
