Abstract: A lighting device includes a light source that emits an illumination light. The light source includes a first group of light emitting diodes (LEDs) to emit a first light, a second group of LEDs to emit a second light, and a third group of LEDs to emit a third light. The second light is warmer light than the first light, and the third light is cooler light than the first light. The lighting device further includes a first difference amplifier that controls a first current flow through the second group of LEDs at least based on a magnitude of a current flowing through the light source. The lighting device also includes a second difference amplifier that controls a second current flow through the third group of LEDs at least based on the magnitude of the current flowing through the light source.

Abstract: A system can include an object having a communication device, where the communication device of the object broadcasts a first signal from a first location within a volume of space at a first time. The system can also include a first electrical device and a second electrical device that receives the first signal in the volume of space. The system can also include a controller communicably coupled to the first electrical device and the second electrical device, where the controller determines a first strength of the first signal received by the first receiver, determines a second strength of the first signal received by the second receiver, scales the first signal relative to the second signal based on the first strength and the second strength, and determines a location of the object in the volume of space based on scaling the first signal relative to the second signal.

Abstract: A driver of a lighting fixture includes a power circuitry configured to provide a first current to a first string of light emitting diodes (LEDs), a second current to a second string of LEDs, and a third current to a third string of LEDs that emit a third white light. The driver further includes a controller that controls the power circuitry to change an amount of the first current, an amount of the second current, and an amount of the third current to adjust a CCT of an output light provided by a lighting fixture. The output light includes two white lights from among the first white light, the second white light, and the third white light, where the first current, the second current, and the third current are adjustable independent of each other.

Abstract: A digital fencing system includes a first lighting fixture that includes a first communication module, and a second lighting fixture that includes a second communication module. The digital fencing system also includes a control device configured to receive first information from the first lighting fixture. The first information is related to a wireless signal transmitted by a mobile entity and received by the first lighting fixture. The control device is further configured to receive second information from the second lighting fixture. The second information is related to the wireless signal transmitted by the mobile entity and received by the second lighting fixture. The control device is also configured to transmit a control message to the mobile entity to control a movement of the mobile entity based on a location of the mobile entity with respected to a permitted area.

Abstract: A lighting device includes a first string of light emitting diodes (LEDs) configured to emit a warm white light having a warm Correlated Color Temperature (CCT). The lighting device further includes a second string of LEDs configured to emit a cool white light having a cool CCT. The lighting device also includes green light LEDs that emit a green light. A flux of the green light is controlled based on a flux of the cool white light or a flux of the warm white light. The flux of the warm white light and the flux of the cool white light change proportionally with respect to each other.

Abstract: A lighting fixture includes a light source that emits an illumination light and a receiver configured to receive a lighting control message from a photo sensor device. The lighting fixture further includes a lighting controller configured to adjust the illumination light based on the lighting control message. Adjusting the illumination light by the lighting controller includes changing a Correlated Color Temperature (CCT) of the illumination light.

Abstract: A system for locating an object in a volume of space can include a first electrical device disposed in the volume of space and having a first antenna and a first controller, where the first controller reduces a first default range of the first antenna to a first effective range. The system can also include an object disposed within the first effective range, where the first controller recognizes a first signal, using the first antenna, that identifies the object in the first effective range.
