  • Publication number: 20240103520
    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.

  • Publication number: 20060266645
    Abstract: An electrochemical biosensor strip has a base, an electrode system, an optional spacer and a cover. The electrode system is laid on the base. The spacer is laid on the electrode system and exposes a portion of the electrode system for electrical connection with a meter and a different portion of the electrode system for application of a test reagent. The cover is covered on the spacer to form a cavity. Between the test reagent and the base, a hydrophilic layer is laid between them for increasing the binding effect of the test reagent on the base. The hydrophilic layer is laid on the area excluding from the electrode system and laid on the electrode system about 50% to 0% of the electrode system corresponding to the test reagent. The hydrophilic layer will not interfere with signal transmission of the electrode system so the test is more accurate.

  • Publication number: 20050133736
    Abstract: An ion implantation apparatus. An ion implantation chamber has a movable work piece support holding one or more work pieces and a connecting housing between the ion implantation chamber and an accelerator thereof. A plurality of collectors with saw-toothed protrusions are mounted on the interior surface of the ion implantation chamber and the housing, and grounded to fix contaminant particles moving within the ion implantation apparatus.
