Abstract: A product package intended to hold a product for sale. The product package includes one or more light sources disposed therein and configured to direct light through one or more openings in the exterior of the product package, in order to entice customers to purchase the product. Various techniques are used such as diffusing light before letting it exit the product package.

Abstract: Analog control of a plurality of light sources, such as light-emitting diodes (LEDs), to generate multiple colors of light. An electronic circuit controls three or more analog outputs in response to a single analog input, each of the analog outputs controlling a different one of the light sources.

Abstract: An adapter is disclosed that converts a received stereo audio signal into a signal having more than two channels, such as a surround sound signal. For example, the adapter may convert a stereo signal to a 5.1 signal. Other types of surround sound may alternatively be generated from the stereo signal. In addition, the adapter may have no active electronic components. That is, the adapter may require no power source to perform the signal conversion other than the power inherent to the stereo signal itself. Where the adapter requires no source of power and uses relatively few parts, the adapter may be assembled in a relatively small housing.

Abstract: An illumination apparatus configured to generate multi-color light in a pleasing fashion and that may be operated in a variety of visual modes. The illumination apparatus may further include one or more speakers that may operate in a variety of audio modes. The illumination apparatus may further produce light that is suitable for treating light-deficiency disorders and/or for reducing eyestrain.
