Abstract: Liquid crystals compositions designed to turn red or orange and remain red or orange at or above a specified temperature, such as 115 degrees Fahrenheit, are shaped in the outline of the word “HOT” and are embedded on the top surface of the heating element of stoves or on the window surface of wall ovens and toaster ovens so that they glow red or orange and instantly alert anyone that the heat element of the stove or the window is too hot to touch. For use on smooth cooktop stoves, including warming trays, the liquid crystal display is embedded in a top surface of the smooth area of glass or metal that forms the beating element of the stove. For wall ovens and toaster ovens, the liquid crystals are embedded in the vertical window surface. A versatile heat alert safety device is removably attachable to any hot surface whether flat or rounded.

Abstract: Heat alert safety device for warning individuals that a surface containing multiple heating elements has residual heat wherein a configuration of light emitting diodes that comprises a heat warning symbol specific that one heating element receives electric power whenever a specified temperature of that heating element is exceeded. A controller of the LEDs receives information from a heat sensor adjacent the heating element. The symbols are positioned so that an observer approaching a heating element of the stove from any direction when the heating element is dangerously hot can readily see and understand the heat warning symbol for that heating element. In one embodiment, the heat warning symbol comprises an arrangement of LED's that forms a perimeter around the heating element interrupted by the letters “HOT” or partially encircles the heating element but is positioned between the heating element and an observer approaching the heating element.

Abstract: Heat warning safety device comprising thermochromic ink or epoxy in the form of a heat warning symbol sprayed, stamped, stenciled, silk screened, embossed to the hot surfaces of appliances. The device is invisible when cold and is visible when a threshold temperature is reached. In a second version when cold the device shows only the outline of the warning symbol and when hot shows the full symbol. A plurality of these versions of the devices can be placed on various parts of appliances to maximize the effectiveness of the warning system and to tailor it both to children who need guidance as to where to look for said symbols and to adults as to whom the impact is greatest when the warning symbol appears from a point of invisibility. Alternatively, the warning symbol appears on the lip of a mug and advertises the staying power of the hot liquid therein.

Abstract: Heat alert safety device for warning individuals that a surface is hot wherein a fiber optic cable runs from an electric light source to a heat warning symbol. The cable has a plurality of fibers connected at a first end thereof to the light source and transmits light from the light source beginning from the first end to the second end of the cable and shines light out of the second end of the cable to a predetermined symbol adjacent the second end of the cable. The symbol is readily visible when illuminated to an observer who can also readily see the surface and the symbol communicates that the surface of the stove, in particular, the heating element, is dangerously hot. A controller controls the light source Whenever a specified surface temperature is reached, the symbol is lit and remains lit as long as said specified surface temperature is maintained.

Abstract: A device for automatically rocking a stroller. Winding structure includes a connecting rod, whose first end is eccentrically mounted to the spring structure and whose second end is equally eccentrically mounted to the wheel axle extension so that the forward movement of the stroller winds the spring structure. The rocking structure includes a rod whose far end is mounted eccentrically to the wheel axle extension and whose forward end is less eccentrically mounted to the spring structure to ensure that the rod assumes a reciprocating motion during the unwinding of the spring structure. The user switches from winding mode to rocking mode. In an alternative embodiment a first rod attached to the shaft includes a lever that assumes different positions, the different lever positions changing the degree to which a second rod is eccentrically mounted to the spring structure and determining whether the device is in winding or rocking mode.

Abstract: A freezer insert, a warmer insert or a freezer/warmer insert designed for use inside plastic food containers conforms to the bottom of the various sizes and shapes of the most popular plastic food containers sold under brand names such as Ziplock, Glad, Tupperware. The insert is a flat disk and contains known gels or thermal preservation fluids useful for portable cooling or warming. The insert also can rest on the walls of the container if those walls slope outward in the direction of the opening. The inserts divide the container vertically into cool, extra cool or hot compartments for different types of food. The disk can be round, square or of other shape. The inserts are stackable to allow efficient storage, for example in a freezer or kitchen cabinet.

Abstract: A hot-button type heat alert safety device attachable to a surface, such as metal or glass, for warning individuals that the surface is hot, comprising a thermochromic composition, a button-shaped container for housing the composition, having a convex face, the convex face overlying said composition and the container container being transparent in at least a portion of the container overlying the thermochromic composition.

Abstract: Liquid crystals compositions, i.e. cholesteric liquid crystals or various types of liquid crystal polymers designed to turn red at or above a specified temperature and remain red at or above that temperature and that are shaped in the outline of the word "HOT" (or for cooktop stoves of a ring surrounding the heating element that may be interrupted by such an outline) are embedded on the top surface of the heating element of stoves or on the window surface of wall ovens and toaster ovens so that they glow red and instantly alert anyone that the heat element of the stove or the window is too hot to touch. For use on electric stoves including small mobile electric stoves called hot plates, the device is an improved electric coil whose central recessed area contains liquid crystals. For use on smooth cooktop stoves, including small mobile cooktop stoves called warming trays, the liquid crystal display is embedded in a top surface of the smooth area of glass or metal that forms the heating element of the stove.
