Abstract: Various embodiments of the present disclosure are generally directed to processing conversions of digital assets to fiat currency. An example method includes obtaining a conversion rate for a digital asset via an API, providing the conversion rate via a client device, receiving a digital asset conversion request and executing a digital asset conversion within a configurable time period. Executing the digital asset conversion includes causing digital asset units to be debited from the digital asset user account and causing fiat currency units to be credited to a fiat currency user account. The method further includes dynamically providing a notification of execution of the digital asset conversion via the client device, updating account balance data objects associated with the digital asset user account and the fiat currency user account, and subsequent to executing the digital asset conversion, executing a fiat currency transaction (e.g., a settlement) with a digital asset exchange system.

Abstract: A laser light-based control system that makes use of intelligent motion tracking camera-based technologies to allow a performed to select notes, to provide a range of values for controlling device components (such as a fader), and to select a volume or magnitude value for a selected note (or output value). The control system may be configured in some implementations with the ability to filter out other light sources to only monitor a particular light from a source using real time video processing. This allows the control system to function to track simple and also complex laser animations and beam interruptions and, in response to the results of such tracking, to generate control signals for a digital music instrument to generate an endless amount of note values and variables (e.g., volume, pitch, and so on) in a 2D space or, in some preferred embodiments, a three dimensional (3D) space.
