Abstract: Systems, methods, and computer program products for providing and managing a lighting system. A lighting device of the system is configured to receive an activation signal from a user interface of the lighting device, an external communication device, or another lighting device. In response to receiving the activation signal, and if certain operational conditions are met, the lighting device may activate a light source and transmit another activation signal. Additional lighting devices receiving the activation signal from the first lighting device may also activate their light sources and retransmit the activation signal. Data carried by the activation signals and signals received from one or more sensors in each lighting device may be used by the lighting device to determine whether to activate its light source, and one or more characteristics of the light to be emitted.

Abstract: A laminated and insulated glass window construction, especially for use in entryway glass lites. The window includes first and second glass sheets mounted in facing, spaced apart relationship. An adhesive layer is disposed on an outer surface of the first glass sheet and a third glass sheet is adhered to the first glass sheet by the adhesive layer. A decorative element may be disposed within the space created between the first and second glass sheets. This decorative element may be a separate panel or a resinous layer adhered to an inside surface of one of the first and second glass sheets.
