Abstract: Various embodiments include a lamp control unit coupled to or part of one or more light emitting diode (LED) based lamps. The lamp control unit can receive, from a lamp commissioning application of a mobile device via a wireless protocol, one or more commissionable lighting parameters to configure light output of the LED based lamps. The lamp control unit can lock access to change the commissionable lighting parameters with a password. One or more operational lighting parameters of the lamp control unit can be adjusted via a control interface (e.g., an adjustable voltage dimmer) other than the wireless protocol. The lamp control unit can drive the LED-based lamps based on the operational lighting parameters and the commissionable lighting parameters.

Abstract: Some embodiments of this disclosure operate a LED-based lamp module in conjunction with a controller, such as a general-purpose mobile device or other light control system. The operations can include producing light at a current correlated color temperature (CCT) from a light source comprising an LED set of different color LEDs; authenticating a connection between a mobile device and the LED-based lamp module; receiving a target CCT for the LED-based lamp module; determining a target LED driving condition that produces the target CCT based on a color mixing plan stored in the LED-based lamp module; and adjusting the current CCT towards the target CCT by adjusting a current LED driving condition towards the target LED driving condition.

Abstract: Synthesizer models for emulating musical instruments can be improved using an analysis model that compares the output signal of the model to a recording of a desired sound and derives a residual signal that can be used to correct the model. When the original model is a good one, the residual signal is small and takes much less memory to store than is required for a sampled sound.
