摘要:
A washing machine includes an inner tub arranged in an outer tub and a rotatable wave wheel. As every 1 kg load is increased, the height difference h1 between the clothes and water satisfies the formula h1=(πD2h−4V1)/(KπD2), wherein D is the diameter of the inner tub, h is the height of the wave wheel, V1 is the volume of the wave wheel, and K is the optimal clothes load between the wave wheel and the inner tub within the wave wheel height. The clothes overturn periodically while rotating along with the wave wheel. The clothes move towards the center of the wave wheel along the wave wheel while moving upward, overturn outwards in a uniform wobble way after reaching the climax of the wave wheel and fall to the bottom of the inner tub along the inner tub wall, and move towards the center of the wave wheel again.

A washing machine for automatically adding the detergent by negative pressure comprises a water inlet, a detergent container and a tub. A main inflow waterway and a rinse waterway are provided between the water inlet and the tub. A dosing container which communicates with the detergent container is provided between the rinse waterway and the tub. A venturi tube is provided in the main inflow waterway. Due to venturi effect, the main inflow water stream becomes narrower and the water inflowing velocity is accelerated, so that a relative vacuum area which communicates with the dosing container is formed at the rear side of the venturi tube outlet, negative pressure is generated in the dosing container, and the detergent in the detergent container.

Methods and systems for detecting trees in aerial imagery are provided. A method for detecting trees in aerial imagery may include training a pixel-level classifier to assign a tree or non-tree label to each pixel in an aerial image. The method may further include segmenting tree and non-tree regions of the labeled pixels. The method may also include locating individual tree crowns in the segmented tree regions using one or more tree templates. A system for detecting trees in aerial imagery may include a trainer, a segmenter and a tree locator.

Apparatus and methods for storage and transmission of recipe data (process parameters) for the molding of articles in an injection molding apparatus. A controller includes a flow control microcontroller (MCU) that receives recipe data from a recipe storage microcontroller (MCU) mounted to a mold of an injection molding machine, the recipe storage MCU storing the recipe data defining process parameters for the molding of articles in the mold. The flow control MCU executes instructions for controlling valve pin motions according to the recipe data. In one embodiment, a human operator interface is provided for transmitting data to and/or from at least one of the recipe storage and flow control MCU's, allowing the operator to monitor, modify and/or control the process parameters during a molding cycle and/or to create a modified or new recipe for subsequent storage on the recipe storage MCU.

Systems, methods, and devices for performing channel estimates to address the Doppler Effect in wireless communications are described herein. One aspect of the disclosure provides an apparatus for wireless communication. The apparatus comprises a receiver configured to receive coded data tones during a first symbol over a communication channel. The apparatus further comprises a processor. The processor is configured to estimate a common phase offset and amplitude of the communication channel based on pilot tones received over the communication channel. The processor is configured to determine, prior to decoding, a residual phase offset per data tone based on a phase difference between an estimate of the coded data tones and a reference symbol. The processor is configured to estimate update channel state information of the communication channel based on the determined estimated common phase offset, amplitude, and the determined residual phase offset per data tone.

There is provided a disk drive including a disk drive base, a disk rotatably coupled to the disk drive base, and a spindle motor attached to the disk drive base and configured to support the disk for rotating the disk with respect to the disk drive base. The disk drive further includes a filter component. The filter component includes a filter housing coupled to the disk drive base, and a filter element disposed within the filter housing for filtering disk rotation induced airflow. The filter element includes a coarse section and a fine section. The coarse section has a porosity greater than a porosity of the fine section.
