  • Patent number: 11159734
    Abstract: An automatic object tracking system is configured to perform an automatic object tracking method. A horizontal coordinate axis and a vertical coordinate axis are defined in image capturing data captured by a handheld device. When a feature object is recognized, a sampling frame is set to surround the feature object, and a reference point is set within the sampling frame. A horizontal distance and a vertical distance from the reference point to a target coordinate are calculated. When the horizontal distance or the vertical distance is larger than a horizontal threshold, a turning command is issued to move the reference point towards the target coordinate horizontally or vertically by at least one horizontal unit or by at least one vertical unit. In case that plural feature objects are recognized, the handheld mobile device chooses a proper one of the plural feature objects timely to perform the panning shot.

  • Publication number: 20210178510
    Abstract: Systems and techniques are directed to a Swappable Retractable Tool Tip (SRTT), which is designed as a next generation of friction stir welding tools and retractable tool tips. The disclosed SRTT may be “swappable,” having different types of retractable tool tips that can be assembled and employed as a part of the SRTT. A SRTT system can include at least: a blank tool holder, a piston, and a retractable tool tip. In operation, the blank tool holder allows air to flow to cause movement of the piston and the retractable tool tip. For example, compressed air can push up on the piston and the retractable tool tip, retracting it into a “home” position inside of the blank tool holder. Also, the SRTT can include springs that push down on the piston and the retractable tool tip, extending the tip into an “extended” position outside of the blank tool holder.

  • Patent number: 10987844
    Abstract: The present disclosure provides a clamping assembly in operative connection with a mold of an injection-molding apparatus. The clamping assembly includes a fixed plate, a rear plate, a plurality of tie bars, a movable plate, a driving module, and a temperature adjuster. The rear plate is spaced apart from the fixed plate. The tie bars are interlinked with the fixed plate and the rear plate and provided with a plurality of channels. The movable plate, between the fixed plate and the rear plate, is capable of moving with respect to the fixed plate along the tie bars. The driving module interlinks the rear plate and the movable plate. The temperature adjuster is employed to supply a fluid into the channels to remove heat from the tie bars, thereby preventing non-uniform thermal expansion of the tie bars, and hence preventing the structural wear and flash issues.
