Abstract: The calibration system of the farming machine receives images from each camera of the camera array. The images comprise visual information representing a view of a portion of an area surrounding the farming machine. To calibrate a pair of cameras including a first camera and second camera, the calibration system determines a relative pose between the pair of cameras by extracting relative position and orientation characteristics from visual information in both an image received from the first camera and an image received from the second camera. The calibration system identifies a calibration error for the pair of cameras based on a comparison of the relative pose with an expected pose between the first pair of cameras. The calibration system transmits a notification to an operator of the farming machine that describes the calibration error and instructions for remedying the calibration error.

Abstract: A method for detecting image information includes: acquiring at least one sample of image pair to be processed; calculating a reconstruction loss function of the second feature extraction model based on the first image samples and the first reconstructed image feature information; calculating an adversarial loss function of the third feature extraction model based on the second reconstructed image feature information and the first image samples; optimizing the first model parameters in the first feature extraction model based on the reconstruction and the adversarial loss function to generate the optimized first feature extraction model; inputting the acquired image pair to be processed into the optimized first feature extraction model to generate the difference information. The method reduces the first feature extraction model's dependence on the labeled data and improves the model's recognition efficiency and accuracy by using the samples without the labeled difference information.

Abstract: 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.

Abstract: A method, device and system for forwarding a multicast data packet are provided. The system is an extended bridge constructed by a controlling bridge and a port extender. The controlling bridge transmits a multicast data packet with an ETAG having a multicast ECID via a cascade port, and the multicast ECID directs to egress ports in different VLANs of the multicast group on a port extender connected with the cascade port. The port extender receives the packet with the ETAG via an upstream port connected with the controlling bridge, searches for multicast duplication information matching the multicast ECID, duplicates the packet for each egress port based on the multicast duplication information, removes the ETAG of each copy of the packet, adds a port identification and a VLAN identification of each egress port to each copy of the packet, and transmits the packet containing the VLAN identification via each egress port.

Abstract: A digital-to-analog converter (DAC) circuit includes a least significant bit (LSB) set of capacitors, each commonly coupled to an LSB node, and a most significant bit (MSB) set of capacitors, each coupled to an MSB node. A section-coupling capacitor couples the LSB and MSB nodes. The LSB node exhibits a parasitic capacitance, which tends to introduce a jump error voltage. Digital input signals are applied to the LSB and MSB capacitors, and in response, an analog output signal is developed on the MSB node. A compensation capacitor coupled to the MSB node has a compensation capacitance selected to offset the jump error voltage introduced by the parasitic capacitance. The compensation capacitor is enabled when all of the LSB capacitors are coupled to digital input signals having a logic ‘0’ state. Otherwise, the compensation capacitor is disabled (e.g., left in a floating state).

Abstract: Open Pairings occurring during airline operations are repaired n at a time (where n is an integer) in near real time through use of two solution paths, one involving one-way fixes, and the other matching transformations. From the resulting multiple solutions, one is selected which is of least cost to the airline.

Abstract: An automated real time crew optimization engine for repairing crew problems including open flights, open pairings, and broken crews in airline operations, which generates multiple solutions in conformance with solution constraints by preprocessing the crew problems to generate potential solutions, and optimizing the potential solutions to provide optimized solutions. The preprocessing includes the use of self-connection methods, skipping-leg methods, and an extend-out-broken crew method. Potential solutions are generated by swap methods including a one-way swap method, a two-way swap method, and a three-way swap method. A depth-search-first algorithm and a shortest path algorithm are applied to the potential solutions to find optimal solutions.
