Component supply system
A loose component supply device in which components scattered on stage are imaged by camera. Because the viewing angle of the camera is α>0, a side surface of the component is imaged. Based on the image data of the component, an index value specifying a size of the side surface of the component is calculated. Then, in a case in which the calculated index value matches a set value, it is determined that it is possible to hold the component. In other words, in a case in which there is a certain distance between multiple components, from imaging a side surface of the component, if an index value that specifies the size of the side surface of the component matches the set value, it is determined that it is possible to hold the component. |

Systems and methods for private authentication with helper networks
Helper neural network can play a role in augmenting authentication services that are based on neural network architectures. For example, helper networks are configured to operate as a gateway on identification information used to identify users, enroll users, and/or construct authentication models (e.g., embedding and/or prediction networks). Assuming, that both good and bad identification information samples are taken as part of identification information capture, the helper networks operate to filter out bad identification information prior to training, which prevents, for example, identification information that is valid but poorly captured from impacting identification, training, and/or prediction using various neural networks. Additionally, helper networks can also identify and prevent presentation attacks or submission of spoofed identification information as part of processing and/or validation. |

There is a clear need for a high efficiency solar power system that supplies electricity at a competitive cost and that provides for an on-demand supply of electricity as well as energy storage. By combining aspects of concentrated solar power and concentrated photovoltaics, the present invention provides a device that enables the conversion of sunlight to electricity at very high efficiencies and that enables the transmission of thermal energy to heat storage devices for later use.

Organic electroluminescent device
An organic electroluminescent device adopts a TADF material as a first host material (6) of a green light unit (302) to sensitize a green phosphorescent material serving as a first guest material (7). A portion of triplet excitons are converted into singlet excitons through inverse gap crossing, and thus decrease of the triplet exciton concentration results in narrowing of the recombination region, thereby preventing the triplet excitons from diffusing into a blue light layer (4) to emit light, so as to realize a green light spectrum containing no blue light component. And because an energy level difference between red light and blue light is relatively large, carriers in a red light unit cannot be easily transferred to the blue light layer, and therefore it is not easy for a blue light component to appear in a red light spectrum. Accordingly, the light-emitting spectrums of red/green subpixels in the organic electroluminescent device with a shared blue light layer do not contain blue light, thereby effectively broaden the range of applicable combinations of luminescent materials and improving the display performance of the device. Moreover, a hole-blocking layer is not required, and thus the structure of the device is effectively simplified, and the operation voltage is lowered; in the meantime, the process difficulty is reduced, and the product yield is increased, thereby reducing the production cost. |
