Abstract: A luminaire includes a luminaire control circuit and a disinfection light source to emit a disinfection light in an ultraviolet (UV) band for disinfecting a vicinity of a physical space of a target pathogen that is exposed to the disinfection light. The UV band is 200 nanometers (nm) to 230 nm wavelength. The luminaire receives a control signal based on at least the mounting height of the luminaire. The luminaire adjusts a UV radiation threshold limit based on the control signal. The luminaire controls, via a driver circuit, the disinfection light source over a dose cycle to emit the disinfection light continuously or during the plurality of periods for disinfecting the vicinity to substantially obtain the target pathogen UV radiation level and restrict the total UV radiation threshold exposure level by the adjusted UV radiation threshold limit based on the control signal.

Abstract: A method for conditioning and maintaining power with predictive load compensation using an uninterruptible power supply system is disclosed. The method includes measuring an electrical input from a primary power supply using analog sensors and transmitting the input through an impedance to introduce a controlled delay. During the delay, input parameters and downstream system effects are determined based on telemetry sensor data. Digital identities are generated for the electrical input and the downstream load and compared to a stored digital identity representing historical conditions. Using the comparison, a system simulation is performed with analog twinning to predict downstream system responses. The predicted response is used to adjust a power converter parameter, modifying the electrical input to an intermediate output that compensates for voltage fluctuations and harmonic distortions.

Abstract: Disclosed is a method for training a graphics processing neural network with a patch-based approach, which involves calculating an overlapping size and an invalid size of an output of each of at least one of multiple feature extraction layers of the graphic processing neural network according to a predetermined cropping scheme, dividing an input image into first patches in the forward pass and the first gradients into second patches in the backward pass to run streamline operation of the first and second patches. Before training, each first patch overlaps neighboring first patches at adjacent edges. In the forward pass, an invalid portion of the output of each of the at least one of the feature extraction layers cropped out based on the predetermined cropping scheme and a corresponding invalid size. Such method secures streamline operation in favor of enhanced memory utilization in training and accurate model prediction.
