Publication number: 20240030649Abstract: An electronic equipment includes a device and a cable. The device includes a casing, a fixing element, a sealing element, an electronic element and a first connecting portion. The fixing element is disposed inside the casing and includes a first snapping portion. The sealing element is sandwiched between the casing and the fixing element. The first connecting portion connects the electronic element located inside the casing. The cable includes a second connecting portion, a wiring portion and a body connected between the second connecting portion and the wiring portion. The body penetrates through an opening of the casing and an opening of the sealing element. The body has a second snapping portion and a pressing zone. When the second snapping portion snaps with the first snapping portion, the second connecting portion connects the first connecting portion, and the sealing element presses against the pressing zone.Type: ApplicationFiled: December 21, 2022Publication date: January 25, 2024Inventors: Kuan-Wen WANG, Pei-Sheng TSAI

Patent number: 8834447Abstract: A transdermal drug delivery patch and a method of controlling the drug release of the transdermal drug delivery patch by near-IR are disclosed. The transdermal drug delivery patch comprises a substrate, carriers and drugs. The drugs are encapsulated in the carriers, and the carriers having the drugs are disposed on a surface of the substrate. The carriers are formed of biodegradable polymers, and nano-particles with a photothermal conversion effect are loaded in the carrier. When the carriers are punctured into the skin and the nano-particles in the carrier absorb the near-IR, the near-IR is converted into heat by the nano-particles to melt the carrier and thus releasing the drugs encapsulated in the carrier into the skin. Accordingly, the speed of releasing the drugs encapsulated in the carrier can be controlled accurately by the near-IR.Type: GrantFiled: August 23, 2011Date of Patent: September 16, 2014Assignee: National Cheng Kung UniversityInventors: Mei-Chin Chen, Dong-Hwang Chen, Kuan-Wen Wang, Bo-Hung Lai

Publication number: 20120060817Abstract: A stove structure includes a stove body. The stove body has a heat source portion and a wall portion. The wall portion has an inner wall and an outer wall. The inner wall and the outer wall are connected by a plurality of cross-section conducting members. Between the inner wall, the outer wall and the cross-section conducting members is provided with a low conductivity coefficient member. The cross-section conducting members extend the heat conduction distance and decrease the contact area of heat conduction. The lower conductivity coefficient member and the cross-section conducting members lower the heat conduction rate. The temperature of the outer wall is lowered to a second temperature and the temperature in the heating portion of the stove body is kept at the first high temperature.Type: ApplicationFiled: September 13, 2011Publication date: March 15, 2012Inventors: Po-Tang WANG, Hui-Chun Yu, Kuan-Wen Wang, Rih-Yang Wang, Ting-Yu Wang

Patent number: 7884384Abstract: The invention provides a light emitting diode device and a fabrication method thereof. The device comprises a pair of electrodes and one of which is electrically contacted with a holder, an LED chip fixed in the holder, a wrapping material formed in the holder and covering the LED chip, and a plurality of nanocrystals having a quantum dot state dispersed in the wrapping material. The nanocrystals satisfy the formula, Zn1-xCdxS and 0<x<1, and can produce a luminous wavelength of about 400 nm to 800 nm. The device further comprises a plurality of organic molecules bonded to the surface of the nanocrystals. Because a molecular interaction occurs between the organic molecules and the wrapping material, the nanocrystals are uniformly dispersed in the wrapping material to improve luminous uniformity. Furthermore, the wrapping material can protect the nanocrystals from oxidation to avoid efficiency decaying.Type: GrantFiled: October 18, 2007Date of Patent: February 8, 2011Assignee: Industrial Technology Research InstituteInventors: Shu-Ru Chung, Kuan-Wen Wang, Chih-Cheng Chiang

Patent number: 7678359Abstract: The invention provides a preparation method of Zn1-xCdxA quantum dot capable of emitting white light, in which A is S or S1-ySey; 0<x<1 and 0<y<1. The method includes preparing a sulfur-containing organic solution; mixing a zinc-containing precursor and a cadmium-containing precursor with an organic acid, and dissolving them in a co-solvent to obtain a homogeneous solution; and mixing sulfur-containing organic solution with the homogeneous solution to produce Zn1-xCdxA quantum dot.Type: GrantFiled: January 29, 2008Date of Patent: March 16, 2010Assignee: Industrial Technology Research InstituteInventors: Shu-Ru Chung, Kuan-Wen Wang, Li-Kuei Lin, Chen-Yu Huang, Chih-Cheng Chiang
