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.

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.

Abstract: The present invention provides a heat dissipating assembly for a heat element comprising a board on which at least a heat source, heat conductive layer and a heat dissipating sheet are set. The heat conductive layer is formed between the heat dissipating sheet and the board by squeeze bonding, thermal fusion or ultrasonic fusion. The heat conductive layer is made up of a material possessing the properties of quick heat conduction and compressive flexibility. While the heat conductive layer is adhered by squeeze bonding, thermal fusion or ultrasonic fusion, heat is conducted by its entire surface. The present invention is able to raise the heat dissipating efficacy and draw out the heat from the heat source quickly, therefore, increases the brightness and durability of the light source.

Abstract: The present invention discloses a package structure of a stack-type light-sensing element and a package method thereof, wherein firstly, a substrate is provided; next, a signal-processing IC chip and a light-sensing chip are sequentially stacked above the substrate in bottom-up sequence; next, lead lines are used to electrically connect the substrate with the signal-processing IC chip and the light-sensing chip in order to form a unitary light-sensing element. The present invention has the advantages that light-sensor signals are directly processed and then output to a display device, and that the volume of a light-sensing element can be reduced to such an extent that it can be easily applied to miniature electronic products. In contrast with the conventional light-sensing element needing massive volume of electronic circuits to process signal and also needing minute and complicated assemblage, the present invention has superior novelty and futurity.
