A method includes the steps of obtaining a frame from an image sensor, the frame comprising a number of pixel values, detecting a change in a first subset of the pixel values, detecting a change in the second subset of the pixel values near the first subset of the pixel values, and determining an occupancy state based on a relationship between the change in the first subset of the pixel values and the second subset of the pixel values. The occupancy state may be determined to be occupied when the change in the first subset of the pixel values is in a first direction and the change in the second subset of the pixel values is in a second direction opposite the first direction.

Image analysis techniques

A fixture configuration module comprises a connector configured to be removably coupled with a light fixture. The fixture configuration module also comprises fixture control circuitry communicatively coupled to the connector and configured to control the light fixture to produce light in accordance with a range of a lighting parameter. The range includes at least a subset of values supported by the light fixture for producing light. The fixture configuration module further comprises range control circuitry communicatively coupled to the fixture control circuitry and configured to wirelessly receive the range at least while the connector is uncoupled from the light fixture, and designate the range to the fixture control circuitry while the connector is coupled to the light fixture.

Light fixture with NFC-controlled lighting parameters

A lighting management system includes communications circuitry, processing circuitry, and a memory. The memory stores instructions, which, when executed by the processing circuitry cause the lighting management system to receive a message from a lighting fixture via the communications circuitry, the message indicating a proximal presence of a detected mobile device to the lighting fixture, and performing one or more actions in response to receipt of the message. By performing the one or more actions upon receipt of the message as described above, a lighting system may be provided with additional functionality that enhances the lighting system.

Light management system for wireless enabled fixture

An image sensor includes an active pixel array including a number of pixels and image sensor control circuitry configured to perform a read operation only on a subset of the pixels of the active pixel array such that pixels not in the subset remain inactive. By reading out only the subset of pixels in the active pixel array and keeping the remaining pixels inactive, the temperature of the active pixel array may be reduced compared to a conventional read out process, thereby reducing thermal noise in the resulting pixel data.

In one aspect, luminaires are described herein having sensor modules integrated therein. In one aspect, a luminaire described herein comprises a light emitting face including a LED assembly. A sensor module is integrated into the luminaire at a position at least partially overlapping the light emitting face. In another aspect, a luminaire described herein comprises a LED assembly and a driver assembly. A sensor module is integrated into the luminaire along or more convective air current pathways cooling the LED assembly or driver assembly.

LED luminaire having enhanced thermal management

Tenon-mounted lighting fixtures with high structural integrity are provided. In one embodiment, the lighting fixture has a housing that has an integrally formed tenon cradle, which is configured to receive a tenon of a light pole. A light source is also mounted on a bottom side of the housing. The tenon cradle is between a first bolt boss and a second bolt boss, and is in communication with a rear opening of the housing. The first and second bolt bosses may be integrally formed in the housing. The tenon cradle includes multiple ribs. An arcuate cross rib resides in a first plane in which a first bolt shaft of the first bolt boss and a second bolt shaft of the second bolt boss reside. An axial rib intersects the arcuate cross rib and runs perpendicular to the first plane.

A distributed, parallel, image capture and processing architecture provides significant advantages over prior art systems. A very large array of computational circuits&#x2014;in some embodiments, matching the size of the pixel array&#x2014;is distributed around, within, or beneath the pixel array of an image sensor. Each computational circuit is dedicated to, and in some embodiments is physically proximal to, one, two, or more associated pixels. Each computational circuit is operative to perform computations on one, two, or more pixel values generated by its associated pixels. The computational circuits all perform the same operation(s), in parallel. In this manner, a very large number of pixel-level operations are performed in parallel, physically and electrically near the pixels. This obviates the need to transfer very large amounts of pixel data from a pixel array to a CPU/memory, for at least many pixel-level image processing operations, thus alleviating the significant high-speed performance constraints placed on modern image sensors.

Light fixture control

Method and system for image based occupancy detection

An intelligent sign, such as an exit or other informational sign, is equipped with control circuitry, at least one sensor, and in certain embodiments, a communication interface. The control circuitry can monitor sensor data from the associated sensors. The sensor data bears on various conditions or events associated with the area that is associated with the exit sign. Based on the sensor data, the intelligent sign can provide one or more operations. A sign operation may include any operation provided by the intelligent sign. When equipped with the communication interface, the intelligent sign may control its own internal operation and/or control the operation of other entities based on the sensor data, the type of sensor data, the content of the sensor data, and the like. The intelligent sign may also share sensor data or other information derived from the sensor data with other entities.

Intelligent signage

An apparatus may include a solid-state lighting panel including multiple solid-state light emitters and an input module that is configured to receive an input signal from a lighting panel group controller that is configured to collaboratively control multiple solid-state lighting panels.
