An intelligent audible device is provided that is constructed to monitor for an event, such as actual or elapse time, or a sensor exceeding a threshold. Responsive to the event, a sound input transducer is activated, and an output sound signal representing an intended message is projected into the local environment by a sound output transducer. The sound input transducer captures the actual sound projected into the local environment. The captured actual sound is processed and compared to the output sound signal. In this way it may be confidently determined if the intended message was actually properly projected into the local environment.

Verifying messages projected from an intelligent audible device

A verifiable display is provided that enables the visual content of the display to be detected and confirmed in a variety of ambient lighting conditions, environments, and operational states. In particular, the verifiable display has a display layer that is capable of visually setting an intended message for human or machine reading, with the intended message being set using pixels. Depending on the operational condition of the display and the ambient light, for example, the message that is actually displayed and perceivable may vary from the intended message. To detect what message is actually displayed, a light detection layer in the verifiable display detects the illumination state of the pixels, and in that way is able to detect what message is actually being presented by the display layer.

Optically determining messages on a display

In one embodiment, an optical state monitor includes an a light source detection layer for detecting electromagnetic radiation from an associated good. The optical state monitor uses a processor to evaluate the detected radiation, and make a comparison to a pre-defined optical state profile for the good. By making this comparison, the optical state detector is able to determine a quality for the good. In a particular construction, the optical state detector has an integral light source, and the light detection layer is printed as a thin film device. In this way, a stand-alone self-contained sensor is constructed for determining the good's current quality.

Optically determining the condition of goods

Embodiments describe a display integration scheme in which an array of pixel driver chips embedded front side up in an insulator layer. A front side redistribution layer (RDL) spans across and is in electrical connection with the front sides of the array of pixel driver chips, and an array of light emitting diodes (LEDs) is bonded to the front side RDL. The pixel driver chips may be located directly beneath the display area of the display panel.
