Abstract: A method for determining a plant growth curve includes obtaining color images and depth images of a plant to be detected at different time points, performing alignment processing on each color image and each depth image to obtain an alignment image, detecting the color image through a pre-trained target detection model to obtain a target bounding box, calculating an area ratio of the target bounding box in the color image, determining a depth value of all pixel points in the target boundary frame according to the aligned image, performing denoising processing on each depth value to obtain a target depth value, generating a first growth curve of the plant to be detected according to the target depth values and corresponding time points, and generating a second growth curve of the plant to be detected according to the area ratios and the corresponding time points.

Abstract: A beverage maker has pulse-width modulation (PWM) signals and preset flow velocity values stored therein and supplies a liquid through a flow velocity control method, which includes setting a target flow velocity value; setting one of the preset flow velocity values matching the target flow velocity value as a matched flow velocity value and setting one of the PWM signals corresponding to the matched flow velocity value as an executing PWM signal; supplying the liquid according to the executing PWM signal and sensing an actual liquid flow velocity; performing an algorithm on the executing PWM signal and a sensed liquid temperature and dispensing time to generate an adjusted PWM signal when a difference exists between the actual and the target flow velocity value; and finally, changing the liquid flow velocity according to the adjusted PWM signal, so that the beverage maker supplies the liquid at the target flow velocity stably.

Abstract: A method for determining a height of a plant, an electronic device, and a storage medium are disclosed. In the method, a target image is obtained by mapping an obtained color image with an obtained depth image. The electronic device processes the color image by using a pre-trained mobilenet-ssd network, obtains a detection box appearance of the plant, and extracts target contours of the plant to be detected from the detection box. The electronic device determines a depth value of each of pixel points in the target contour according to the target image. Target depth values are obtained by performing a de-noising on depth values of the pixel points, and a height of the plant to be detected is determined according to the target depth value. The method improves accuracy of height determination of a plant.

Abstract: A beverage brewing method implemented via a beverage brewing system includes the steps of setting multiple brewing parameters; reading an identification code of a beverage brewing material to generate an identification message; confirming the identification message indicates a brewing parameter that is a valid data and choosing one brewing parameter that corresponds to the identification message to generate a matched brewing parameter; downloading the matched brewing parameter to form a brewing implementation parameter for brewing the beverage brewing material; and forming a feedback message in the brewing process to change the matched brewing parameter into an invalid data to prevent repeated brewing of the beverage brewing material. Therefore, once a selected beverage brewing material has been brewed, the brewing parameter corresponding thereto will be changed into an invalid data and the same beverage brewing material would not be brewed repeatedly to ensure a stable quality of the brewed beverage.

Abstract: A coffee maker includes a water storage device having a water tank and a water outlet piping communicating with the water tank; a driving device having a driving motor and a driving shaft; and a swing device having a rotating mechanism mounted on the driving shaft and a shifting mechanism connected to the water outlet piping and moving along with the rotating mechanism when the latter rotates. The water outlet piping is brought by a horizontal rotational movement of the rotating mechanism and a linear movement of the shifting mechanism to swing and shift in a spiral rotational course from a center point to outer and inner areas of a filter in a reciprocating motion while pouring water at controlled volume and stability, enabling ground coffee beans on the filter to be quickly and evenly extracted by water to release aromatic smell and sweet flavor just like drip brewing manually.

Abstract: A leadless semiconductor package mainly includes a plurality of inner leads, a chip pad, a semiconductor chip and a molding compound. A non-conductive ink is filled between every two of the inner leads, and couples the inner leads to the chip pad so as to be in replacement of the conventional tie bars. The semiconductor chip is disposed on the chip pad and electrically connected to the inner leads. Moreover, the molding compound is formed on the inner leads and the non-conductive ink for encapsulating the semiconductor chip. The non-conductive ink prevents the exposed bottom surfaces of the inner leads from contamination by the molding compound without attaching an external tape during molding. Also the inner leads can be in a multi-row arrangement and the chip pad can be disposed in an optional location.
