Abstract:
The invention provides a display system which incorporates two display devices. A first is larger than a second, but with a lower resolution. The higher resolution second display is a directional display and it has its output area within the overall output area of the first display. This system integrates a general display for long range viewing by multiple people with a short range higher resolution display for interaction with one or a small number of users.
Abstract:
A lighting script—for use by a lighting controller to control at least one luminaire to render illumination effects, as the video content is outputted in a space illuminated by the at least one luminaire, synchronously with the outputting of the video content—is generated as follows. Frame image data of the video content is processed to determine at least one colour palette of the frame image data. A sequence of illumination effects—to be rendered during the outputting of the video content and which is modifiable by a user—is displayed to the user. The displayed sequence conveys at least one illumination colour derived from the determined colour palette to be rendered in at least one of the illumination effects. The generated lighting script is for rendering the modified sequence of illumination effects.
Abstract:
A lighting control apparatus (106) may include an accelerometer (118), a wireless communication interface (112), and a secure connection (125) for securing the lighting control apparatus to a surface. The secure connection may be configured to transfer motion imparted on the surface to the accelerometer. A controller (108) may be coupled with the accelerometer and the wireless communication interface. The controller may be configured to: receive, from the accelerometer, a signal representative of motion sensed by the accelerometer; determine, based on the signal from the accelerometer, that the sensed motion satisfies a motion criterion; and transmit, over the wireless communication interface to a lighting unit (104) or a lighting system bridge (102), data configured to cause one or more lighting units to emit light having one or more selected properties.

Methods and apparatus related to a LED-based lighting unit (10; 110; 210; 310; 410) having a radar for presence detection. A radar circuit (140; 240; 340A; 340B; 440) may be electrically coupled to conductive wiring (25; 125; 225; 325; 425) of the LED-based lighting unit that at least selectively powers the radar circuit and at least selectively powers the LEDs. In some implementations, an antenna coupled to the radar circuit may be formed from the conductive wiring and optionally at least partially isolated from any current flowing through the LEDs.
Abstract:
Methods, apparatus and computer-readable media for controlling a lighting unit are disclosed herein. In some embodiments, a controller may be operably coupled with one or more light sensors. The controller may, in some embodiments, be configured to receive, from the one or more light sensors, one or more signals indicative of light detected by the one or more light sensors. The controller may facilitate transition of one or more light sources of a lighting unit between first and second lighting states responsive to a determination, based on the one or more signals, that a change in a property of the light detected by the one or more light sensors satisfies a predetermined criterion, such as a threshold rate of change of the property of the detected light.
Abstract:
Methods and systems for providing enhanced augmented reality features and enhancements are disclosed such as an AR support system (100) using lighting units (LU1) in a lighting system (100) to improve performance of augmented reality devices (20). The lighting system (100) may also take advantage of features of the augmented reality devices (20) to improve the safety and performance of the lighting system (100). The lighting units (LU1) include sensors and communication capabilities that detect situations as to when the augmented device would need to be assisted by the lighting network. Finally a method to provide assistance information to the augmented reality device while optimizing energy savings is also described.
Abstract:
Methods, lighting control systems, mobile computing devices and computer-readable media are described herein for graph-based navigation through an environment(100). In various embodiments, a graph (220) including a plurality of nodes and a plurality of edges may be provided, e.g., by a lighting control system(130), to mobile computing devices (350) such as smart phones and tablets carried through the environment. Each node may correspond to a location of a lighting effect produced by a particular light source within the environment. Each edge may correspond to a path between two nodes. Data indicative of a path travelled through the graph by one or more mobile computing devices between a first node corresponding to a first location and a second node corresponding to a second location may be used to update the graph. Mobile computing devices may utilize the graph to calculate optimal paths (220) and/or guide users through the environment.
Abstract:
A lighting system for providing a lighting scene in an environment occupied by a user, the system comprising:—a plurality of illumination sources, each source having a respective location sensor arranged to detect a location of the respective source relative to at least one point defined independently of the lighting scene and at least one of the sources further having at least one of an orientation sensor arranged to detect an orientation of the at least one source and a luminaire type sensor arranged to detect a type of the at least one source; and—a controller arranged to provide control signals to the plurality of sources in order to control the sources to render the lighting scene; wherein the controller is arranged to—determine an effect location of an illumination effect from the at least one source based on the detected location and at least one of the detected orientation and detected luminaire type of said at least one source and—adapt the control commands based on the detected source locations and the determined effect location for the at least one source, thereby rendering the lighting scene relative to said at least one point.
Abstract:
Disclosed are methods and apparatus for lighting control. For example, a user may commission a touch-controlled luminaire (106) to emit light output having various lighting properties dependent on a manner in which the touch-controlled luminaire is touched subsequently. In particular, a user may use an electronic mobile device (102) such as a smart phone, tablet computer, or a wearable computing device (e.g., computing glasses, smart watches) to associate a touch event profile indicative of a manner in which a touch-controlled luminaire was touched (e.g., tapped, swiped, etc.) with a lighting control action. The user may then provide that association to the touch-controlled luminaire. When the touch-controlled luminaire is later touched in the same manner, it may adjust its light output in accordance with the lighting control action. Operation and commission of gesture-controlled luminaires (706) is also described herein.
Abstract:
An LED-based lighting unit (100, 200, 300, 400, 1000, 1100, 1200, 1300, 1400, 1500) may be installable into a luminaire (108, 208, 308, 408, 1008, 1108, 1208, 1308, 1408, 1508) to cause the luminaire to be responsive to applied forces and/or movements to control one or more properties of light emitted by the lighting unit. The lighting unit may include one or more LEDs (102), an accelerometer (114), and a controller (112). The controller may: receive, from the accelerometer, a signal representative of a measured mechanical force applied to or movement of the luminaire in which the LED-based lighting unit is installed; determine, based on the signal from the accelerometer, that the measured mechanical force or movement corresponds to one or more predetermined forces or movements; and energize the one or more LEDs to emit light having one or more properties selected based on the determination.
