A system and method for determining vehicle position uses light based communication (LBC) signals and a received signal strength indicator (RSSI) to determine the vehicle position. Each vehicle includes a LBC system having an array of transmitting light emitting diodes (LEDs) and an array of receiver photodiodes for transmitting and receiving pulsed light binary messages. Each LBC system has a controller coupled to the transmitter diodes and receiver diodes. The controller includes a vehicle communication module that may be executed by a processor to determine the distance. The processor models a first distance between a first transmitting LBC system and a first receiving LBC system, then models a second distance between a second transmitting LBC system and the first receiving LBC system, and then determines the distance between the first vehicle and the second vehicle using trilateration of the first distance and the second distance.

Techniques and user interfaces (UIs) are disclosed for controlling a solid-state luminaire having an electronically adjustable light beam distribution. The disclosed UI may be configured, in accordance with some embodiments, to provide a user with the ability to control, by wireless and/or wired connection, the light distribution of an associated solid-state luminaire in a given space. The UI may be hosted by any computing device, portable or otherwise, and may be used to control any given light distribution capability provided by a paired luminaire. In accordance with some embodiments, the user may provide such control without need to know details about the luminaire, such as the quantity of solid-state lamps, or their individual addresses, or the address of the fixture itself. In some cases, the disclosed techniques may involve acquiring spatial information of the space that hosts the luminaire and/or providing user-selected distribution of light within that space.

Techniques and architecture are disclosed for gesture-based control techniques for lighting systems. In some cases, the lighting system may include a camera and/or other suitable componentry to interpret gestures made by a user for controlling light output. In some such cases, the gesture performed and/or the location of the gesture may determine how the light output is controlled. In some cases, the gestures may be performed by moving a mobile computing device, such as a smartphone, tablet, or dedicated light controller device. In some such cases, sensors included in or otherwise operatively coupled to the computing device (gravitational sensors, accelerometers, gyroscopic sensors, etc.) may be used to detect the movement of the device and the related gestures. The gestures may be used to navigate a user interface that allows a user to control light output by adjusting different attributes of the light output, such as light intensity and color.

Gesture-based control techniques for lighting systems

Techniques are disclosed for providing spatially-defined and/or distance-defined light-based communications within a vehicle/roadway environment. In some embodiments, the techniques can be used to vary the data content of a given transmitted light-based communications signal based on factors such as position, distance, and/or proximity of the transmitting source and the receiver. In some embodiments, the techniques can be used to vary the processing or other handling of a received light-based communications signal based on one or more of such factors. In some instances, the disclosed techniques can be utilized to tailor light-based vehicle-to-X (V2X) communications for dissemination between and among vehicles and infrastructure in a vehicle/roadway environment. To that end, a node may host a transmitter (e.g., laser, LED, or other solid-state light source) configured to emit such light-based communication signals and/or a receiver (e.g., a photosensor or other light-based data input device) configured to sense such signals.

Techniques and graphical user interface for controlling solid-state luminaire with electronically adjustable light beam distribution

Techniques and architecture are disclosed for a lighting system for contained environments, such as elevators or other such environments. The lighting system can include one or more luminaires and/or one or more display devices that include tunable output controlled to automatically change the ambient lighting and/or presentable content (e.g., imagery, video, audio) based on one or more conditions related to the contained environment. Conditions that can be used in controlling the lighting system output within the contained environment can include, for example, the position or operation of the contained environment, the control of the contained environment, the occupancy within the contained environment, the time of day at the location of the contained environment, and the calendar date at the location of the contained environment. In some cases, the lighting system may constitute the general illumination within the contained environment, but may be supplemental as well.

Lighting system for contained environments

Techniques are disclosed for providing a decentralized intelligent nodal lighting system. The intelligent nodal lighting system may be controlled using a wireless protocol, such as Wi-Fi, and each lighting node in the system may have its own independent Wi-Fi address and may receive, store, and interpret commands from a wirelessly connected controller. Each intelligent light node may contain a CPU and memory for storing and interpreting commands from the controller to achieve a desired light color, intensity, or quality. In some embodiments, individual lighting nodes may be dynamically added or removed from the lighting system without interrupting the system's operation.
