Abstract: Power receptacle control circuitry includes load switching circuitry, communications circuitry, sensor circuitry, processing circuitry, and a memory. The sensor circuitry includes a light sensor. The processing circuitry is coupled to the load switching circuitry, the communications circuitry, the sensor circuitry, and the memory. The memory includes instructions, which, when executed by the processing circuitry cause the power receptacle control circuitry to selectively deliver power to a load via the load switching circuitry, detect a modulated light signal via the light sensor, and join a group of devices based on the modulated light signal.

Abstract: The present disclosure relates to a lighting fixture that includes a driver module and at least one other module that provides a lighting fixture function, such as a sensor function, lighting network communication function, gateway function, and the like. The driver module communicates with the other modules in a master/slave scheme over a communication bus. The driver module is configured as a slave communication device, and the other modules are configured as master communication devices. As such, the other modules may initiate communications with the driver to send information to or retrieve information from the driver module.

Abstract: A fixture configuration module comprises fixture control circuitry and range control circuitry. The fixture control circuitry is configured to control a light fixture to produce light in accordance with a range of a lighting parameter. The range identifies at least a subset of values of the lighting parameter supported by the light fixture to produce light. The range control circuitry is communicatively coupled to the fixture control circuitry and comprises a mechanical switch. The range control circuitry is configured to designate the range to the fixture control circuitry in response to the mechanical switch being positioned into at least one of a plurality of switch positions into which the mechanical switch is positionable.

Abstract: An LED-based lighting fixture sets or adjusts a parameter of a drive signal that is used to drive its LEDs to be more compatible with the camera system; the camera system sets or adjusts an image capture parameter to be more compatible with the LED-based lighting fixture, or a combination thereof. The drive signal may be a PWM signal with a variable PWM frequency and/or duty cycle, a variable DC signal, or any combination thereof. The parameter of the drive signal that may be set or adjusted includes, but is not limited to, a PWM period, PWM frequency, PWM duty cycle, amplitude of the active and inactive portions of the PWM signal, and the like. The image capture parameter that may be adjusted includes, but is not limited to, frame rate, frame period, integration time, gain, shutter type (i.e. rolling shutter, global shutter, etc.), and the like.
