Abstract: A thin film thermometer has multiple temperature sensors that individually appear within certain concealing features of the decal under different temperature ranges, otherwise blending into the concealing features and thereby disappearing into the design. Among other uses, this thermometer may be implemented as an adhesive bandage or refrigerator magnet, and may include special features such as a hologram, heat blocking backing, and ink-preserving adhesive tie coat. Also, enhanced visual effects are achieved through the coordinated multiple activation of temperature sensors.

Abstract: Print heads with arcuate printing surfaces are used to apply images to elongated, laterally curved slats prior to their assembly into Venetian blinds. Each print head includes a print head casing having a concave or convex printing surface forming an arc shape. The print heads are distributed in series along a slat path, which is defined by a conveyor. One or more ink wells are coupled to the print head casing; each ink well may contain a separate color of ink. Many print jet orifices are evenly distributed along the printing surface, and may be arranged in an array with multiple rows and columns, for example. Each print jet orifice is coupled to one of the ink wells by a supply path. During the printing process, slats are longitudinally advanced along the slat path past the print heads. A controller regulates the slat's position relative to the print heads, and controls the position using the conveyor.

Abstract: A decal has multiple temperature sensors that individually appear within certain concealing features of the decal in accordance with different prescribed temperatures, otherwise blending into the concealing features and thereby disappearing into the design. The decal may depict an image of an animal, fish, flower, abstract form, or another design, such as a photograph, cartoon, sketch, or other representation. The image includes multiple separate concealing features, such as spots, fins, flower petals, abstract shapes, or other components of the decal's image. These features may have one color in common, or different concealing features may have different colors. The feature color(s) contrasts with one or more background colors in the design, which serve to visually separate the concealing features. The temperature sensors are scattered throughout the design in a visually pleasing manner.
