A power supply system providing communication from a master module to at least one slave module via transients, to alter operation of a load, is provided. The master module output a supply voltage that is either a normal supply voltage or a reduced supply voltage. The outputted supply voltage depends on input corresponding to a communication to be sent to the slave module to alter operation of the load of the slave module. The slave module receives the supply voltage and interprets the received supply voltage, which may vary between the normal and reduced supply voltages, to determine what the communication from the master module is. The slave module then uses information from the communication to appropriately alter operation of its load.

Systems and methods for pulse-based binary communication are provided. An example system may include a transmitting device and a receiving device. The transmitting device may be configured to generate a supply voltage for use in operating the receiving device and to cause at least one pulse to occur in the supply voltage, the at least one pulse being based on a binary value. The at least one pulse may comprise, for example, a temporary change in the supply voltage. The receiving device may be configured to receive the supply voltage from the transmitting device, to detect the at least one pulse in the supply voltage and to determine the binary value based on the at least one pulse. The receiving device may then perform an action based on the binary value.

Modular multichannel light sources connector systems and methods are provided. A lighting assembly includes substrates, each with a respective plurality of ports and conductive path configurations. Each path configuration includes a plurality of conductive paths between the respective plurality of ports. At least two conductive path configurations are the same. A connector couples one of a plurality of first ports on a first substrate to one of a plurality of second ports on a second substrate. A multichannel power supply's outputs are each coupled to an associated conductive path on the first substrate. A first light source is coupled to two conductive paths on the first substrate, and to a first output. A second light source is coupled to two conductive paths on the second substrate, corresponding to the conductive paths on the first substrate, and to a second output, different from the first output.

An auto-sensing switching regulator, and systems and methods including same, is disclosed. The auto-sensing switching regulator includes a switching regulator and a controller coupled thereto. The controller is configured to provide a control signal to the switching regulator to increase the output voltage while receiving a current sense signal representative of a current output of the switching regulator, and to provide the control signal in response to the current sense signal to set the output voltage at a set value corresponding to a value at which the current output stops increasing with an increase in the output voltage. A system to drive a light source includes a current regulator configured to provide a constant current output to the light source and an auto-sensing switching regulator coupled to the current regulator, and configured to receive an input voltage from a voltage supply and provide an output voltage to the current regulator.
