Abstract: A device comprises an enclosure having a rear opening adapted to receive a light beam from a light source, a front opening adapted to emit a modified light beam, and internal walls extending between the rear opening and the front opening. The light beam is modified according to a perimeter of the front opening. A light shaping assembly comprises a two-dimensional array formed of a plurality of such devices, each one of the plurality of devices being adapted to receive a light beam from a corresponding light source.

Abstract: A combination comprises at least one lens and at least one prism. The at least one lens and the at least one prism are in an optical path of a corresponding at least one light source. The combination is configured to direct light radiating from the at least one light source toward a projector lens.

Abstract: A light shaping assembly comprises a printed circuit board (PCB) and a two-dimensional (2D) array formed of a plurality of rows, each row comprising a plurality of light sources mounted on the PCB, each light source comprising a pair of supporting pins for mounting the light source on the PCB. The supporting pins of each light source are bent at an angle that is increasing as a function of a distance between each light source and a selected point on the PCB so that light beams emitted by the light sources are collectively directed toward a common target.

Abstract: Radio frequency-enabled lighting-fixture management systems, apparatus, and methods are described. One implementation includes a wireless communication component and a controller that is integrated into the radio frequency-enabled lighting-fixture management unit. The controller is configured to obtain operational values of a luminaire driver or a luminaire. The controller is further configured to provide the obtained operational values to the wireless communication component for transmission.

Abstract: A light control system including a light source and a light management unit (LMU) operative to receive a light output control signal and to control a light output emitted from the light source, wherein the LMU controls the light output from the light source based on the light output control signal.

Abstract: Irrigation control systems and method of operating an irrigation system are described for irrigation systems including one or more orifices, e.g., sprinkler heads, arranged in one or more irrigation lines. The control system can include one or more sensors such as moisture meters and flow meters that measure water output associate with the irrigation system. The irrigation control system can be linked to one or more networks for access, e.g., through the Internet. The control systems and methods can utilize moisture calibration to avoid or reduce a need for continuous use of moisture sensors.

Abstract: Systems and methods are described for the control of lighting systems at individual light-fixture, local, regional, and larger-geographical-area levels that also distribute electrical power to consumers. One implementation comprises a hierarchical lighting-control system including an automated network-control center that may control up to many millions of individual lighting fixtures and lighting elements, regional routers interconnected to the network-control center or network-control centers by public communications networks, each of which controls hundreds to thousands of individual light fixtures, and light-management units, interconnected to regional routers by radio-frequency communications and/or power-line communications, each of which controls components within a lighting fixture, including lighting elements, drivers, sensors, and other devices. Systems and methods of using synthetic events for calibration and control of lighting systems are also described.
