Abstract: The present invention relates to a tunable compensation device and method for received signals. The tunable compensation device comprises a first antenna, a compensation device, a second antenna and a signal processing unit. The first antenna receives a first radio wave. The compensation device receives and compensates the first radio wave. The second antenna receives a second radio wave. The signal processing unit receives the compensated first radio wave and the second radio wave as to control the compensation by the compensation unit for the first radio wave. The tunable compensation method is characterized in that the first radio wave received by the first antenna is used to modulate the second radio wave received by the second antenna.

Abstract: An EMI (Electrical Magnetic Interference) test system is provided. The system includes a testing table, a horizontal antenna, a vertical antenna and a processing unit. The testing table is used for supporting an Equipment Under Test (EUT). The horizontal antenna is positioned at a first location in an EMI chamber. The vertical antenna is positioned at a second location in the EMI chamber. The vertical antenna and the horizontal antenna are used for receiving the electromagnetic wave radiated from the EUT, and producing a vertical electric wave and a horizontal electric wave respectively. The processing unit is coupled to the vertical antenna and the horizontal antenna for transforming and analyzing the vertical electric wave and the horizontal electric wave.

Abstract: An adapter includes a wireless card, and a bracket fixed on the wireless card. The bracket includes a base plate that has an aperture for positioning an antenna terminal, and a mask extended from the base plate for substantially shielding an end of the antenna terminal welded on the wireless LAN card inside the mask.

Abstract: A fuel and air mixing device includes a tank for receiving fuel therein and a compressor on a top of the tank is connected to a first port of a mixing device and a valve assembly having a pipe connected to a second port of the mixing device. A siphon is connected to the valve assembly and extends in the fuel in the tank so as to siphon the fuel to go through the mixing device to form smaller particles which are entered the tank and mixed with air provided by the compressor. The mixture is then sent to an outlet of the valve assembly. A control unit is connected to the valve assembly and the compressor for a convenience of operation to the users.

Abstract: A laser measuring device includes a housing, a laser head, two levels, a power supply, and a control knob. Thus, the housing has a non-symmetrical structure, so that when one of the casings of the housing is removed, the adjusting screws of the laser head are entirely exposed outward from the housing, thereby facilitating adjustment of the laser head and the levels.

Abstract: A pedal shaft structure of a bicycle having a second pedaling function is proposed. A shaft tube of the bicycle has a braking unit and a shaft. Pedals are arranged at two ends of the shaft through cranks. The shaft has a main shaft, a second spring and a pair of bearings. The main shaft has a first shaft, a second shaft, a first bushing and a first spring. The second spring is telescoped at the main shaft and one end thereof is fixed to the second shaft. The pair of bearings are arranged at two ends of the shaft tube and telescoped at two ends of the main shaft. The braking unit comprises an insertion hole formed at the shaft tube, an insertion rod inserted into the insertion hole, a steering component, a steel rope connected between the steering component and the insertion rod.

Abstract: A scooter usable for figure scootering, including: a scooter frame having a frame body for a user to step thereon; a steering mechanism disposed at a front end of the scooter frame for controlling turning direction of the scooter; a front wheel pivotally disposed at a bottom end of the steering mechanism; a rear wheel pivotally disposed under bottom face of the frame body; and an auxiliary wheel pivotally disposed under bottom face of the scooter frame behind the rear wheel. When the front and rear wheels contact with the ground, the auxiliary wheel is higher than the ground by a certain height. When the front end of the scooter is lifted, the rear wheel and the auxiliary wheel contact with the ground for performing figure scootering.

Abstract: A measuring tape assembly includes a housing, a first level mounted on the housing, a second level mounted on the housing and having a direction different from that of the first level, and a scrolling tape rotatably mounted in the housing. Thus, measuring tape assembly can be used to adjust and calibrate the level of the article in two directions by the first level and the second level vertical to each other.

Abstract: An electric fan includes a base, a drive unit, a fan blade, and a direct current power source. The drive unit is mounted on the base, and includes a direct current fan motor and an electrical socket connected to the fan motor. The fan blade is coupled to and is driven rotatably by the fan motor. The direct current power source is coupled electrically to the fan motor, and includes a storage battery and an electrical plug connected to the storage battery. When the electrical socket and the electrical plug are interconnected, the storage battery provides power to the fan motor for operation of the electric fan.

Abstract: A bicycle having dual-purpose pedals is provided, wherein the structure of a main shaft tube of the bicycle is improved. The structure has a main shaft, a first spring, a gear bushing, a crank, a second spring, a washer and a fixing unit. The main shaft is received in the main shaft tube. The first spring is telescoped onto the main shaft. The washer, the second spring, and the gear bushing are received in order in a crank hole of the crank. The washer is fixed at the distal end of the main shaft by a screw. The fixing unit passes through and is fixed on the main shaft tube. The bicycle can be used as a conventional bicycle having a one-up-one-down, 360-degree, circular rotation pedaling function. The user can also change and control the two pedals to accomplish a same-up-same-down pedaling function for enhancing entertainment during use.
