  • Patent number: 11996630
    Abstract: An antenna structure includes a ground element, a first radiation element, a second radiation element, a third radiation element, and a nonconductive support element. The first radiation element is coupled to a first grounding point on the ground element. The second radiation element has a feeding point. The second radiation element is adjacent to the first radiation element. The third radiation element is coupled to a second grounding point on the ground element. The third radiation element is adjacent to the second radiation element. The first radiation element, the second radiation element, and the third radiation element are disposed on the nonconductive support element. The second radiation element is at least partially surrounded by the first radiation element. The third radiation element is at least partially surrounded by the second radiation element.

  • Patent number: 11996633
    Abstract: A wearable device includes a ground element, a first radiation element, a second radiation element, a third radiation element, a fourth radiation element, and a fifth radiation element. The first radiation element has a feeding point, and is coupled to a first grounding point on the ground element. A slot region is surrounded by the first radiation element and the ground element. The second radiation element is coupled to a second grounding point on the ground element. The third radiation element is coupled to the second grounding point. The third radiation element and the second radiation element substantially extend in opposite directions. The fourth radiation element and the fifth radiation element are disposed inside the slot region. An antenna structure is formed by the first radiation element, the second radiation element, the third radiation element, the fourth radiation element, and the fifth radiation element.

  • Publication number: 20240164569
    Abstract: An automated beverage preparation apparatus includes: multiple pumps for extracting multiple fluid materials stored in multiple material containers, and pushing the extracted fluid materials to move forward; a fluid output device coupled with the multiple pumps and arranged to operably dispense fluid materials to a beverage container; a user control interface arranged to operably generate a control command; a processing circuit arranged to operably generate a corresponding control signal according to the control command; and a pump control circuit arranged to operably control the multiple pumps according to the control signal. The pump control circuit conducts a layered drink making operation under control of the processing circuit to cause the fluid output device to dispense different fluid materials to the beverage container, so as to automatically form a layered drink/gradient drink having at least two color layers within the beverage container.

  • Publication number: 20240162218
    Abstract: An electrostatic discharge device including a gate structure, a plurality of first doped regions, and a plurality of second doped regions. The gate structure is disposed on a substrate. The gate structure includes a body part and a plurality of extension parts. The extension parts are connected with the body part, and an extension direction of the body part is different from an extension direction of the extension parts. The first doped regions are located in the substrate between the extension parts. The second doped regions are located in the substrate at two outer sides of the extension parts. The first doped regions and the second doped regions have different conductivity types.

  • Publication number: 20090098785
    Abstract: Artificial leather includes a non-woven fabric made of split type conjugate fibers and a resin material for submerging or coating the non-woven fabric. The conjugate fibers are made from a first polymer with crystallization of 40% to 95% and a second polymer with crystallization of 1% to 25% by conjugate spinning. Each of the conjugate fibers is split into 24 to 128 segments.
