METHOD AND APPARATUS FOR CONVEYING AGGREGATE PRESENCE INFORMATION USING LIGHT
First Claim
Patent Images
1. A lighting control apparatus comprising:
- a presence sensor to sense a presence of an object and to provide responsive output;
an aggregator module to generate an aggregate presence value based on output of the presence sensor captured over a period of time; and
an output module to generate lighting instructions based on the aggregate presence value, wherein the lighting instructions are configured to cause one or more light emitting diodes (LEDs) to emit a coded light signal that carries information indicative of the aggregate presence value or emit light having a hue selected to convey the aggregate presence value.

Abstract
The present disclosure is directed generally to lighting control, and more particularly, to various inventive methods, systems, computer-readable media (transitory and non-transitory) and apparatus for conveying aggregate presence information using light. For example, in some embodiments, output of a presence sensor over time may be aggregated, and an LED node may cause one or more LEDs to emit light having a property that conveys the aggregated captured output.

19. At least one non-transitory computer-readable medium comprising instructions that, in response to execution of the instructions by a computing device, cause the computing device to:
-
receive, via a light sensor, coded light emitted from a light emitting diode (LED) node; demodulate the coded light to determine an aggregate presence value carried by the coded light signal that represents presence detected by the LED node over a period of time; render, on a display, output indicative of the determined aggregate presence value. - View Dependent Claims (21)

25. A method of providing aggregate presence information, comprising:
-
sensing, by a light emitting diode (LED) node, presence of one or more objects; charging, by the LED node, a capacitor while presence of one or more objects is sensed; discharging, by the LED node, the capacitor while no presence is sensed; and selectively illuminating, by the LED node based on a charge of the capacitor, one or more LEDs in a manner that conveys an aggregate presence value represented by the charge. - View Dependent Claims (27, 30)
