Abstract: An assembly of a chip antenna and a circuit board includes a chip antenna and a circuit board. The circuit board includes a ground layer. The ground layer includes a hollow region formed adjacent to a periphery of the ground layer. The hollow region of the ground layer can be used for configuring an input impedance of the circuit board. The chip antenna is disposed in the hollow region of the ground layer, electrically connecting to the ground layer. The chip antenna includes input impedance. The input impedance of the chip antenna is adjustable to achieve a conjugate impedance match between the chip antenna and the circuit board such that the circuit board and the chip antenna can simultaneously radiate electromagnetic energy.

Abstract: An oxide thin film transistor includes a substrate, a gate layer, an oxide film and a gate insulating layer. The gate layer is disposed on the substrate. The oxide film is disposed on the substrate, and has a source region, a drain region and a channel region. The channel region is located between the source region and the drain region and corresponds to the gate layer. The electric conductivity of the source region and the drain region is greater than that of the channel region. The gate insulating layer is disposed on the substrate and located between the gate layer and the oxide film.

Abstract: A dielectric-loaded and coupled planar antenna includes a ground plane, a radiator, a ceramic substrate and at least one ground coupling electrode. The radiator is formed by extending one side of the ground plane, and a feeding point is formed between the radiator and the ground plane. The radiator extends at least one end portion on the ceramic substrate. The ground coupling electrode is formed on the ceramic substrate by extending the other side of the ground plane. The ground coupling electrode formed on the ceramic substrate and the end portion of the radiator formed on the ceramic substrate are coupled with each other to form a coupling electrode. The present invention can adjust the coupling amount loaded by the ceramic substrate so as to be operated in a desired frequency range. The present invention can be operated in a single-frequency, dual-frequency or multi-frequency condition.

Abstract: A dipole antenna array includes a dielectric substrate; electric tuning elements mounted on a first surface and a second surface of the dielectric substrate; resonance elements and ground elements; and a feed line. Each resonance element includes first resonance parts, second resonance parts and a third resonance part. One of the second resonance parts connects the corresponding first resonance part to the third resonance part. The other second resonance parts respectively connect two neighboring first resonance parts. Each ground element includes first ground parts, second ground parts and a third ground part. One of the second ground parts connects one of the first ground parts to the third ground part. The other second ground parts respectively connect to two neighboring first ground parts.

Abstract: A hemostasis device for controlling bleeding during a surgery is provided. The hemostasis device includes a first portion, which has a close structure, an adjusting device connected with the first portion, and a second portion connected with the adjusting device. The first portion is affixed to the patient to surround the surgical area, and a user adjusts the adjusting device to move the second portion to stress the patient to control bleeding during the surgery.

Abstract: A connecting structure between a liquidizer switch and a circuit board comprises a liquidizer switch and a circuit. The liquidizer switch has a coupling end and the coupling end is defined with a slot. Plural conducting strips are arranged in the slot. The circuit board has a conducting end that is inserted into the slot of the liquidizer switch and contacts with the conducting strips. Thus, welding is not necessary at all, so as to save labor and improve assembly efficiency. On the other hand, the present structure can prevent the circuit board from being damaged because of high temperature produced during welding.
