The disclosure relates to a pressure sensitive indicating device of extremely simplified nature, providing a visual indication of a predetermined pressure threshold level. A typical and advantageous form of the device is a valve or valve extension member for a pneumatic tire, providing a visual indication of the existence or not of a desired pressure level. The device, in its most basic form, comprises an element formed of a natural or synthetic deformable elastomer, designed to expand upon exposure to increasing pressure levels. A covering element is associated with the deformable elastomer and is displaced by distention of the elastomer. By providing the deformable elastomer in a distinctively different color than the cover element, the displacement of the cover upon pressurization to a desired threshold, is readily evident to the observer.

Pressure sensitive indicating device

The application discloses a food probe comprising an optical rod insertable in a body of food, for example, a roast of meat. At its inner end, the rod is configured to receive and transmit axially through the rod a color image of the food in the area contacted by the end of the rod. The image is transmitted to the outer end, where it is desirably magnified for convenient viewing of internal conditions. If desired, the probe may provide for a plurality of viewing areas, for simultaneously viewing the food at multiple depths. The probe preferably is rigid but may be connected to a flexible fiber optic bundle for viewing at a remote location.
