  • Patent number: 10578065
    Abstract: A two-stage intake and two-stage discharge structure of an electrically controlled proportional valve includes a depressurization chamber, which is connected with a guide hole passage, a sensing passage, and a discharge passage. The depressurization chamber is provided therein with a primary diaphragm that drives causes a straight rod having a primary entry opening and a secondary entry opening to move. Through detection conducted in the sensing passage, when the pressure is excessively low, the primary diaphragm moves the straight rod downward to carry out a first stage adjustment, in which the discharge electromagnetic valve is operable to adjust the secondary side pressure for control of depressurization. When the primary diaphragm moves the straight rod further downward to carry out a second stage of pressure output, the secondary entry opening is open to enable a large amount of pressure output.

  • Publication number: 20200051450
    Abstract: The invention provides an audio-visual teaching platform, which includes an analysis subsystem, a recommendation subsystem and a training subsystem. The analysis subsystem provides a learning behavior data to enable the recommendation subsystem to generate at least one presumptive learning mode by using the learning behavior data, thereby generating a recommended learning combination. When the training subsystem receives the recommended learning combination, the training subsystem transmits an audio-visual knowledge content which is set to a user for watching and learning. Accordingly, the invention recommends the audio-visual knowledge content to the users with the same or similar presumptive learning mode, and analyzes the interaction between the users and the audio-visual knowledge content, so as to enable the users to really watch the audio-visual knowledge content and enhance their interest in learning.

  • Patent number: 10379627
    Abstract: A positioning method and a handheld device for performing the method are disclosed. In the method, a handheld device captures images corresponding to positions of a reference when the handheld device points toward the reference. A first image position, a first tilt angle indicative of a rotation angle of the handheld device, and a first pointing coordinate of the reference can obtained. A second pointing coordinate according to the first image position and a second tilt angle are obtained. Therefore, a first displacement vector between the first pointing coordinate and the second pointing coordinate can be computed. A third pointing coordinate can also be obtained. When a substantial movement of the positions of the reference revealed in the images captured by the handheld device is found, an output pointing coordinate is obtained.
