Abstract: In accordance with example systems and methods, an equipment can be operable to emit, using a light emitting device (e.g., an LED), coded light. The coded light can be captured by a camera in the form of image data. The image data can be processed and to data related to the equipment, such as a hardware information, version of software associated with the equipment, status, settings, and other equipment data.

Abstract: An apparatus for generating an isolated power supply voltage and an isolated data signal includes a first pulse generation circuit configured to generate a first pulse signal and a second pulse generation circuit configured to generate a second pulse signal based on an input pulse width modulation (PWM) signal. A transformer circuit including a transformer is coupled to the first pulse generation circuit and to the second pulse generation circuit. The transformer is configured to generate an output pulse signal based on the first pulse signal and the second pulse signal. An isolated power supply circuit is coupled to the transformer circuit and is configured to generate an isolated power supply voltage based on the output pulse signal. A latch circuit is coupled to the transformer circuit and is configured to generate an isolated PWM signal based on the output pulse signal.

Abstract: An addressable power switch for selectively connecting a device to main power in response to command instructions received over a control bus. The control bus supplies a low voltage power source and the addressable power switch includes an energy storage device and charge circuit for deriving a charge current from the low voltage power source and charging the energy storage device. The addressable power switch also includes a latching relay for connecting the device to main power. The change in state of the latching relay is realized through controlling discharge of the energy storage device, which supplies an energy pulse upon discharge. The switch may be used in connection with addressable lighting systems.
