Abstract: A device includes first wires, second wires, resistors, and a processor. Input signals are transmitted from the first wires through the resistors to the second wires. The processor receives a sum value of the input signals from one of the second wires, and shifts the sum value by a nonlinear activation function to generate a shifted sum value. The processor calculates a backpropagation value based on the shifted sum value and a target value, and generates a pulse number based on a corresponding input signal of the input signal and the backpropagation value. Each of a value of the corresponding input signal and the backpropagation value is higher than or equal to a threshold value. The processor applies a voltage pulse to one of the resistors related to the corresponding input signal based on the pulse number.

Abstract: A beverage manufacturing machine includes a heating mechanism, a brewing mechanism and a cooling mechanism. The heating mechanism heats up drinking water and sends the hot drinking water to the brewing mechanism. There are two brewing mechanisms for brewing a hot drink, and the hot drink in a primary cooling bushing exchanges heat with room temperature water to realize a first cooling. The drink after the first cooling reaches a secondary cooling bushing to exchange heat with a low temperature coolant to realize a second cooling to produce an iced drink. The coolant after the heat exchange enters into a coolant buffer and then reflows to a coolant container, and a compressor drives the heat exchanger to lower the temperature of the coolant. Without requiring high skill, this machine makes good-tasted beverages with appropriate concentration or original iced liquid beverage with great aroma.

Abstract: An image retrieval system receives an image for which to identify relevant images from an image repository. Relevant images may be of the same environment or object and features and other characteristics. Images in the repository are represented in an image retrieval graph by a set of image nodes connected by edges to other related image nodes with edge weights representing the similarity of the nodes to each other. Based on the received image, the image traversal system identifies an image in the image retrieval graph and alternatively explores and traverses (also termed “exploits”) the image nodes with the edge weights. In the exploration step, image nodes in an exploration set are evaluated to identify connected nodes that are added to a traversal set of image nodes. In the traversal step, the relevant nodes in the traversal set are added to the exploration set and a query result set.
