Abstract: A system includes a power source and a plurality of modules, where each module has a control for controlling a function of the module and a user input actuatable by a user. The plurality of modules are electrically connected in series with a power conductor electrically connected between each adjacent module, where the power source provides power to each module over the power conductor. In response to actuation by the user of the user input on a select module of the plurality of modules, the control of the select module generates a control signal that is transmitted to each other module over the power conductor, such that the control of each other module controls the associated function in the same manner as the select module.

Abstract: A ceiling panel system includes a panel assembly having a ceiling surface and first and second conductive structures spaced from each other and a first application module configured to engage one of a plurality of locations disposed over the ceiling surface. The first application module includes a wireless receiver, a first contact configured to engage the first conductive structure, and a second contact configured to engage the second conductive structure. The first conductive structure delivers power to the application module. The system also includes a second application module configured to engage a different one of the plurality of locations. The first application module is configured to receive at the wireless receiver wireless commands, and, responsive to receiving wireless commands at the wireless receiver, the first application module transmits the received commands over the first conductive structure to the second application module.
