`
`ABSTRACT
`
`High-brightness LEDs, combined with a processor for
`control, can produce a variety of pleasing effects for display
`and illumination. A system disclosed herein uses high(cid:173)
`brightness, processor-controlled LEDs in combination with
`diffuse materials to produce color-changing effects. The
`systems described herein may be usefully employed to bring
`autonomaus color-changing ability and effects to a variety of
`consumer products and other hausehold items. The system
`may also include sensors so that the illumination of the
`LEDs might change in response to enviroumental conditions
`or a user input. Additionally, the system may include an
`interface to a network, so that the illumination of the LEDs
`may be controlled via the network.

`CIP of U.S. patent application Ser. No. 09/213,659, filed
`Dec. 17, 1998, now U.S. Pat. No. 6,211,626, issuedApr. 3,
`2001.
`
`BACKGROUND OF THE INVENTION
`
`Lighting elements are sometimes used to illuminate a
`system, such as a consumer product, wearable accessory,
`novelty item, or the like. Existing illuminated systems,
`however, are generally only capable of exhibiting fixed
`10 illumination with one or more light sources. An existing
`wearable accessory, for example, might utilize a single
`white-light bulb as an illumination source, with the white(cid:173)
`light shining through a transparent colared material. Such
`accessories only exhibit an illumination of a singletype (a
`15 function of the color of the transparent material) or at best,
`by varying the intensity of the bulb output, a single-colored
`illumination with some range of controllable brightness.
`Other existing systems, to provide a wider range of colared
`illumination, may utilize a combination of differently col-
`20 ored bulbs. Such accessories, however, remain limited to a
`small number of different colared states, for example, three
`distinct illumination colors: red (red bulb illuminated); blue
`(blue bulb illuminated); and purple (both red and blue bulbs
`illuminated). The ability to blend colors to produce a wide
`25 range of differing tones of color is not present
`Techniques are known for producing multi-colared light(cid:173)
`ing effects with LED's. Same such techniques are shown in,
`for example, U.S. Pat. No. 6,016,038, U.S. patent applica(cid:173)
`tion Ser. No. 09/215,624, and U.S. Pat. No. 6,150,774 the
`30 teachings of which are incorporated herein by reference.
`While these references teach systems for producing lighting
`effects, they do not address some applications of
`programmable, multi-colared lighting systems.
`For example, many toys, such as balls, may benefit from
`improved color illumination, processing, andlor networking
`attributes. There are toy balls that have lighted parts or balls
`where the entire surface appears to glow, however there is no
`ball available that employs dynamic color changing effects.
`40 Moreover, there is no ball available that responds to data
`signals provided from a remote source. As another example,
`omamental devices are often lit to provide enhanced deco(cid:173)
`rative effects. U.S. Pat. Nos. 6,086,222 and 5,975,717, for
`example, disclose lighted ornamental icicles with cascading
`45 lighted effects. As a significant disadvantage, these systems
`employ complicated wiring hamesses to achieve dynamic
`lighting. Other examples of crude dynamic lighting may be
`found in consumer products rauging from consumer elec(cid:173)
`tronics to harne illumination (such as night lights) to toys to
`50 clothing, and so on.
`Thus, there remains a need for existing products to
`incorporate programmable, multi-colared lighting systems
`to enhance user experience with sophisticated color chang(cid:173)
`ing effects, including systems that operate autonomously
`55 and systems that are associated with wired or wireless
`computer networks.

`
`This application claims the benefit, under 35 U.S.C.
`§119(e), of the entire disclosure of the following United
`States provisional patent applications ( each of which is
`incorporated herein by reference ):
`U.S. Provisional Patent App. No. 60/199,333, filed Apr.
`24, 2000; and
`U.S. Provisional Patent App. No. 60/211,417, filed Jun.
`14, 2000.
`This application also claims the benefit as a continuation(cid:173)
`in-part of the following
