Abstract: An example luminaire includes a white light source (e.g. LEDs emitting white light in a region of the CIE color chart within three Macadam ellipses below the black body curve) and a violet light source emitting light in a wavelength range of approximately 380 nm to 450 nm (e.g. 405 nm LEDs) for deactivating bacteria, such as Methicillin-Resistant Staphylococcus Aureus (MRSA) on a surface exposed to illumination from the luminaire. A controller coupled to the sources pulses the violet light source at periodic intervals or at random times. When ON, the violet source emits light for deactivating bacteria at an intensity higher than the concurrent intensity of the white light.

Abstract: An example control system includes a set of light fixtures connected to a hub, where each light fixture includes a hub-communication device configured to communicate with the hub and a direct communication device configured to communicate directly with other light fixtures. Together, the light fixtures form a mesh network facilitated by the use of their direct communication devices. An external device communicates an instruction to a light fixture, and the instruction is propagated throughout the mesh network through communications among the light fixtures using their respective direct communication devices. As a result, each light fixture to which the instruction applies receives and complies with the instructions. The light fixtures are also configured to receive instructions from the hub, such that a light fixture is configured to receive instructions over dual networks.

Abstract: Disclosed are an object detection method and a convolution neural network. The method is performed through hierarchical architecture of the CNN and includes extracting groups of augmented feature maps from an input image through a backbone and two other groups of feature maps, identifying positive and negative samples with an IOU-based sampling scheme to be proposals for foreground and background through a proposal-sampling classifier, mapping the proposals to regions on the groups of augmented feature maps through the region proposal module, pooling the regions to fixed scale feature maps based on ROI aligning, fusing the fixed scale feature maps, and flattening the fused feature maps to generate an ROI feature vector through an ROI aligner for object classification and box regression. Because extracted features in the groups of augmented feature maps range from spatially-rich features to semantically-rich features, enhanced performance in object classification and box regression can be secured.

Abstract: Dispensing devices and systems for dispensing materials into a host vessel, optionally containing a host substance, are provided. The dispensing devices are removably attachable, in whole or in part, to a host vessel such as a water bottle or an alcohol bottle. The dispensing devices generally include a rotating capsule (perhaps with a quantity of flavor or nutritional supplements in the capsule) that can be rotated to a position to dispense the contents of the capsule into the host vessel. Depending upon configuration, the act of dispensing may involve squeezing, shaking, or the simple passive step of permitting gravity to act on the contents of the capsule.
