Abstract: An antenna structure includes a first conductor, a high-frequency blocking unit, and a second conductor. The first conductor includes a feeding segment, a coupling segment spaced apart from the feeding segment, and a DC blocking unit connected between the feeding segment and the coupling segment. The high-frequency blocking unit is connected to the coupling segment. The second conductor is spaced apart from the first conductor and couples with the coupling segment. An end of the second conductor is connected to a ground, and the second conductor is provided without connecting any capacitance member and any inductance member. The coupling segment is used as a capacitor electrode for detecting an external object. When the coupling segment is in a capacitor electrode mode, a capacitance value between the coupling segment and the external object is variable according to a distance between the coupling segment and the external object.

Abstract: A communication device includes a assembly and an antenna structure formed on the assembly. The antenna structure has a feeding antenna and a stub antenna spaced apart from the feeding antenna. The feeding antenna has a feeding portion. The stub antenna is suitable for being excited and coupled by the feeding antenna, resonating at a resonance frequency of the feeding antenna, and causing the antenna structure to form two hotspots in an operated frequency band. The shortest distance between the feeding antenna and the stub antenna is defined as a coupling distance. The coupling distance is larger than zero and smaller than or equal to the length of the stub antenna. Thus, electric field value generated from the feeding antenna can be reduced by the stub antenna being excited and coupled by the feeding antenna and resonating at the resonance frequency of the feeding antenna.

Abstract: An antenna module with antenna signal indicating function includes a substrate unit, an antenna unit and a light-emitting unit. The antenna unit has an antenna trace fanned on the substrate unit, and the antenna trace has an antenna body having a grounding portion electrically connect with the antenna body and a feeding portion electrically connect with the antenna body for simultaneously receiving RF signals and DC. The light-emitting unit has a light-emitting element electrically connected between the antenna body and the feeding portion, thus the antenna body and the light-emitting element share the grounding portion. When the user turns on the antenna function of the laptop to receive RF signals, the antenna unit and the light-emitting unit can respectively receive RF signals and DC. Hence, users or bystander could easily judge whether the antenna unit is in use according to light or dark of the light-emitting unit.

Abstract: A pair of multi-purpose glasses includes a frame body having a bridge portion, two side portions at opposite ends of the bridge portion respectively, two temples pivotally secured to the frame body at distal ends of the side portions respectively, and two movable lenses on the frame body. The glasses allow eyes to see through the lenses, or the lenses can be moved away from vision lines of at least one of the eyes. The lenses can be positioned at two sides of the frame body to serve as a pair of normal glasses. Alternative, each lens can be moved away from one eye to be positioned on the other side of the frame. The glasses can then serve, for example, as a pair of cosmetic glasses, or for applying eye drops.

Abstract: A hair dryer provides a multi-stage air current feed device to accelerate the flow velocity of the air current in the hair dryer such that the motor and the fans may generate least noise while the hair dryer is in operation. In addition to multiple stages of the air current feed device, a further added acceleration can be performed by way of applying the Bernoulli's law and the Venturi. Furthermore, a conventional hair dryer also can reduce the noise thereof without lower down the original high flow velocity and the flow rate thereof by way of applying the Bernoulli's law and the Venturi.
