  • Patent number: 7387438
    Abstract: A transparent vacuum formed vessel 1 is filled with a liquid 3 at room temperature that will become a solid at freezing temperature and a low density float material 4. After freezing, the vessel is turned upside down so that upon thawing, the vivid colored float will move to the top of the vessel showing a thaw. The devise can be reused. The same concept can be used as a cooking aid by using a transparent sealed tubular 1 assembly inserted in the food with a solid cylinder 3 that will melt at some critical temperature allowing the low density float to rise to the top of the indicator visibly protruding from the food. More than one meltable cylinder, 3 & 8 and float, 4 & 5 may be used as a warning and ready indicator. Combinations of solid dense particulates and low density materials may also be used for color changing indicators. A permanent magnet attached to a float can be used to trigger an audible alarm, which can be incorporated in various cooking utensils to show cooking temperatures and times.

  • Patent number: 7097353
    Abstract: Disclosed is a temperature indicating method and device. The device embodies a sealed tube containing a liquid and a float. The tube has markings on the exterior indicating temperature zones or, in the alternative, temperature gradients. The method disclosed includes inverting the tube such that the indicator drops to the bottom of the tube and freezing the device at the appropriate temperature level. In use, the device is placed right side up in a container along with other items for which the highest temperature level arrived at is desired to be known. Upon warming, the liquid in the tube melts and the float drops through the liquid to the freezing level of the liquid. By removing the device from the container and comparing the float level in the tube to the markings on the exterior of the tube, the highest temperature or temperature zone that the contents of the container were subjected can be determined.

  • Patent number: 5681110
    Abstract: A water monitoring device including a substantially transparent, buoyant housing which floats in the water. A water temperature transducer provides a voltage proportional to the water's temperature. A processor processes the voltage into a primary digital signal, and a driver drives a digital display according to the primary digital signal. The display is disposed within the housing and displays the temperature such that it can be read through the housing. The display is translucent so that it can be illuminated from its back side. The lower portion of the housing is structured to refract underwater light from outside the housing onto the back of the display. A rechargeable battery powers the device, and a solar panel recharges the battery. The upper portion of the housing is structured to refract light from outside the housing onto the solar panel. A control module controls the rate of recharging of the battery so that the battery's temperature remains within a preferred range.
