Abstract: 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.

Abstract: Techniques are disclosed for providing proper raster line alignment of a camera or other light-sensing device of a receiver device relative to a transmitting light-based communication (LCom)-enabled luminaire to establish reliable LCom there between. In accordance with some embodiments, proper alignment can be provided automatically (e.g., by the receiver device and/or other suitable controller). In accordance with some embodiments, proper alignment can be provided by the user. In some instances in which a user is to be involved in the alignment process, the receiver device may be configured, for example, to instruct or otherwise guide the user in the process of properly aligning the receiver device relative to a given transmitting LCom-enabled luminaire.

Abstract: Techniques are disclosed for position-based actions using light-based communication (LCom). LCom signals can be used to encode or otherwise provide data which in turn can be used to help determine the position of a device receiving those LCom signals. Therefore, LCom can be used to facilitate various actions based on, for example, the position of an LCom receiver determined using data received via the LCom signals. There are numerous use cases for position-based actions using LCom, such as security applications, check-in applications, payments based on location, permissions, and access to information that can all be tied to a location. Actions may include temporarily disabling or enabling the LCom receiver hardware or software (such as disabling device cameras in high security areas), providing another security layer as a result of knowing the device position, and using the LCom receiver position as a part of a larger process.

Abstract: Techniques are disclosed for programming a luminaire with location information, referred to herein as commissioning. Location information may include relative location information (e.g., the position of the luminaire relative to a reference point) and/or absolute location information (e.g., global coordinates for the luminaire). A commissioned luminaire can be configured to emit its location information via light-based communication (LCom). In some cases, the luminaire can be commissioned manually, by hard coding the luminaire with its location either at the luminaire itself or using a device (e.g., a smartphone, tablet, or a dedicated luminaire commissioning device) to program the luminaire with location information. In some cases, the luminaire can be commissioned automatically. In some cases, the luminaire may be configured to provide visual, aural, or tactile feedback to indicate that the luminaire has not received location data or that the luminaire has been moved.

Abstract: Techniques are disclosed for enhancing indoor navigation using light-based communication (LCom). In some embodiments, an LCom-enabled luminaire configured as described herein may include access to a sensor configured to detect a given hazardous condition. In response to detection of a hazard, the LCom-enabled luminaire may adjust its light output, transmit an LCom signal, or both, in accordance with some embodiments. A given LCom signal may include data that may be utilized by a recipient computing device, for example, in providing emergency evacuation routing or other indoor navigation with hazard avoidance, emergency assistance, or both. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, in accordance with some embodiments, via an optical interface or other wired or wireless communication means. In some cases, the network may include a luminaire that is not LCom-enabled yet still configured for inter-luminaire communication.

Abstract: 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.
