Abstract: Methods and apparatus relating to the collection of data regarding a plurality of customers in a retail or entertainment environment. Data may be collected via at least one sensor coupled to at least one lighting fixture in the retail or entertainment environment. In one exemplary implementation, data may be collected by one or more lighting fixtures, and data may be communicated via light generated by any one or more fixtures without perceivably affecting a quality of light generated by the one or more fixtures. A map may be generated based on the collected data to display traffic patterns and/or dwell times of the plurality of customers in the retail or entertainment environment, and such a map may be displayed, for example, via a graphical user interface.

Abstract: The systems and methods descried herein relate in part to intuitive methods for creation and design of lighting sequences, e.g., for theatrical, entertainment or advertising purposes, using a software interface. Additionally, the lighting sequences can be coordinated with control of additional devices. Also described herein is a controller capable of executing programs for lighting sequences and modifying the output and/or execution of the program based on external signals. In this way, the final output can be made responsive to external stimuli, or even interactive.

Abstract: Methods and apparatus for providing theatrical illumination. In one example, a modular lighting fixture (300) has an essentially cylindrically-shaped housing (320) including first openings (325) for providing an air path through the lighting fixture. An LED-based lighting assembly (350) is disposed in the housing and comprises an LED module (360) including a plurality of LED light sources (104), a first control circuit (368, 370, 372) for controlling the light sources, and a fan (376) for providing a flow of cooling air along the air path. An end unit (330) is removably coupled to the housing and has second openings (332). A second control circuit (384) is disposed in the end unit, and electrically coupled to and substantially thermally isolated from the first control circuit. The lighting assembly is configured to direct the flow of the cooling air toward the at least one first control circuit so as to effectively remove heat.

Abstract: Methods and systems for generating one or more scents in conjunction with light. Light of various colors, including dynamic lighting effects, may be generated such that at least one characteristic of the light may be based at least in part on one or more characteristics of a scent or scents, and/or proximate environmental conditions. In one example, one or more LED-based light sources are employed together with a scent-producing facility in a conventional household product (e.g., an integrated air-freshener/LED night light, an LED-simulated candle with scent, etc.).

Abstract: Methods and apparatus for providing illumination in a marketplace. In one example, radiation comprising variable color light is generated using a plurality of LEDs. One or more articles in the marketplace are illuminated with the generated radiation, and the spectral content of the generated radiation is controllably varied over a period of time so that a customer of the marketplace perceives a change in color and/or an illusion of motion associated with the article(s) due to a selective color interaction between the generated radiation and the article(s). Examples of marketplaces include, but are not limited to, consumer environments, work environments, sporting environments, entertainment environments, retail establishments, restaurants, museums, art galleries and the like.

Abstract: One embodiment of the present invention is directed to a control system. The control system may be adapted to control one or more lighting systems (e.g. stand-alone or networked lighting systems). The control system may also have a user interface (e.g. dial or button) such that a user can make a program selection and/or alter a lighting control feature. The control system may also include an enablement system. In an embodiment, the enablement system may be arranged to provide a user and/or installer with the ability to enable a program, program setting or the like. For example, the control system may be programmed with three lighting control programs and the user may only want to select from two of the three programs once the control system is installed. The user may make a selection on the enablement system such that only the two desired programs are available from through the user interface.

Abstract: Separating a source in a stereo signal having a left channel and a right channel includes transforming the signal into a short-time transform domain; computing a short-time similarity measure between the left channel and the right channel; classifying portions of the signals having similar panning coefficients according to the short-time similarity measure; segregating a selected one of the classified portions of the signals corresponding to the source; and reconstructing the source from the selected portions of the signals.
