  • Publication number: 20210111310
    Abstract: A light emitting chip and associated package structure are provided. The light emitting chip includes a substrate, a first type layer, an active layer, a second type layer, a first type electrode and a second type electrode. A second portion of the first type layer is located over the substrate. A first portion of the first type layer is located over the second portion of the first type layer. The active layer is located over the first portion of the first type layer. The second type layer is located over the active layer. The first type electrode is contacted with a top surface and a sidewall of the second portion of the first type layer and contacted with a portion of a sidewall of the substrate. The second type electrode is contacted with the second type layer.

  • Patent number: 10675921
    Abstract: A tire pressure detector disposed at a wheel, wherein the wheel includes a rim and a tire mounted around the rim, with a pressure space formed between the tire and the rim. The rim includes an air tap connected with the pressure space. The tire pressure detector includes a main body movably disposed in the pressure space and provided with a housing space, and a detection module disposed in the housing space. The detection module further includes a sensing unit for sensing the air pressure in the pressure space and producing a pressure signal. A central processing unit of the detection module receives the pressure signal and wirelessly transmits the pressure signal through the wireless transmission unit. Therefore, vibration and waving issue due to imbalance weight is avoided, thus balancing the wheel.
