Abstract: A magnetic multi-pole propulsion array system is applied to at least one external cathode and includes a plurality of magnetic multi-pole thrusters connected adjacent to each other. Each magnetic multi-pole thruster includes a propellant provider, a discharge chamber, an anode and a plurality of magnetic components. The propellant provider outputs propellant. The discharge chamber is connected with the propellant provider to accommodate the propellant. The anode is disposed inside the discharge chamber to generate an electric field. The plurality of magnetic components is respectively disposed on several sides of the discharge chamber. One of the several sides of the discharge chamber of the magnetic multi-pole thruster is applied for one side of a discharge chamber of another magnetic multi-pole thruster.

Abstract: A method of controlling movement of an autonomous mobile apparatus including a driving module, a processor, and a positioning module includes steps of: the processor moving the autonomous mobile apparatus at a default speed from a first location toward a second location along a straight path; the positioning module obtaining data related to a current location; when the processor determines that a distance between the current location and the second location is greater than a predetermined distance, the processor obtaining a deviating direction and a minimum distance of the current location relative to the straight path; the processor setting a movement speed and an angular velocity based on the deviating direction, a tolerant distance, the minimum distance, and the default speed; and the processor controlling the driving apparatus to move the autonomous mobile apparatus at the movement speed and turning the autonomous mobile apparatus at the angular velocity.

Abstract: The present disclosure relates to a method of sampling pixels of an image. The method includes: determining a target area on the image; and sampling pixels from the target area, comprising: sorting background pixels based on a first spectral feature and divide them into a first number of groups; sorting target pixels based on a second spectral feature and divide them into a second number of groups; sampling background pixels from each of the first number of groups; and sampling target pixels from each of the second number of groups.

Abstract: A liquid crystal display driving method is disclosed, where an interlaced image data is received or generated to generate an odd driving signal and an even driving signal, an odd number of gates and an even number of gates are driven according to the odd driving signal and the even driving signal at different signal frame periods, and sources are driven to inverse in their polarities when the driven gates are switched from the ones having the odd number to the even number. Since an alternating number of the sources is reduced, the efficacy of simultaneous promoted power saving and frame quality is achieved.

Abstract: A system for detecting post-operative retained foreign bodies has a data storage unit adapted to receive and store a reference image of a surgical object, and a data processor in communication with the data storage unit. The data processor is configured to receive an image of an internal region of a patient and to receive the reference image from the data storage unit, and the data processor is configured to perform operations based on an algorithm to compare the reference image to at least a portion of the image of the internal region of the patient and determine whether a retained foreign body is present in the patient.

Abstract: The invention relates to an offshore installation method of a wind power generator and its fabrication segments. A prefabricated wind power generator is finished at a first location, and then carried by a ship to a second location for installation, largely saving installation time. With a tower inserted down through a base to shrink height of the generator, the ship can not only effectively diminish shaking posed by wind and sea waves, advancing steadiness of delivery, but also be one with smaller tonnage to save cost.

Abstract: A pressure relief device includes a main body and at least two air control units. The main body has at least one passage therein and two outlets formed at upper and lower ends of the passage. A lid is pivotally connected to each of the outlets. The two air control units are each disposed in the passage close to the lid. An air control device drives the air control units to open/close the lid which is adapted to open/close the passage.
