Abstract: A semiconductor structure includes a first gate structure, a second gate structure coupled to the first gate structure, a source region, a first drain region, and a second drain region. The source region is surrounded by the first gate structure and the second gate structure. The first drain region is separated from the source region by the first gate structure. The second drain region is separated from the source region by the second gat structure. A shape of the first drain region and a shape of the second drain region are different from each other from a plan view.

Abstract: A rendering method for a drone game includes the following steps. Firstly, a drone, a control device, a display device and an information node are provided. The drone includes a plurality of cameras. Then, a plurality of images acquired from the plurality of cameras of the drone are stitched as a panoramic image by the control device, and the panoramic image is displayed on the display device. Then, a ready signal is issued from the information node to the display device, and the control device accesses the drone game through an authorization of the information node in response to the ready signal. Then, at least one virtual object is generated in the panoramic image. Consequently, the sound, light and entertainment effects of the drone game are effectively enhanced, and the fun and diversity of the drone game are increased.

Abstract: A charging apparatus for portable computer can charge various batteries and adjust the charging current by itself. The charging apparatus has a converter, a processor, a PWM circuit connected to the converter and the processor for supplying a charging power, a battery connected to the PWM circuit, a current detection circuit connected to the processor, the PWM circuit and the battery, a battery status detection circuit connected to the battery and the processor, and a power consumption circuit connected to the converter, the PWM circuit and the processor.

Abstract: An automatic voice and image inter-cellular phone security communication system is a combination of a sensor system, an inter-cellular phone system, and a CCD monitor system. When any moving object is detected by the sensor within its effective sensing zone, the sound and image of the moving object is captured by a built-in camera control device and transmitted to the receiving end cellular phone by automatic dialing according to a prescribed phone number stored in a telephone directory. In this way the user at the receiving end may take action against the emergency state immediately.

Abstract: A training and bodybuilding equipment is mainly composed of a base, a main frame, a sliding back board, a weight assembly, a pulley assembly and an accessory assembly, wherein the rope of the pulley assembly is hung onto the sliding board and the movement of the pulley assembly can cause the weight assembly to move up and down, so the users can do weight training for legs and bottom with a correct and safe gestures. Besides, in the present invention the combined use of the top retainers and the bottom retainers at the two ends of the rope and the base with various types of accessory assemblies can achieve the weight training for other parts of human body.

Abstract: The invention provides a full functional weight training gym, and in particular, one that is constructed essentially by supporting a main skeleton on a supporting base with nuts and bolts, and hanging and snapping a sliding backrest with a rope hanging cord loop to drive a pulley block and hence to pull a weights set in a up and down motion. A gym that can be used for weight training on legs with a proper pose is thus obtained. In addition, by combining a set of fittings, including a two-handed long pulling bar, a two-handed short pulling bar, a single-handed short pulling bar, a single-handed ring-shaped pulling bar, a two-handed rope-type pulling bar, a leg band-type pulling ring, a back and forth adjustable plate chair, a foot pressing bar, and a quick snap loop, weight training on all parts of the body involving hands, the chest, the abdominal, the waist, the bottom, the back and shoulders, can be accomplished by only one gym and a less space.

Abstract: A headband radiophone combination set uses a control circuit and a receiver-transmitter circuit to reciprocally transmit or receive signal through an antenna to communicate with the antenna and the receiver-transmitter circuit of a main switching unit for internal, external and regular alternative telecommunication.
