20100184524MOTION SIMULATOR - A motion simulator has a motive device having a base, a moving panel, twelve universal joints mounted on the base and the moving panel and six actuators connected to the universal joints and retractable. A seat assembly is mounted on the moving panel. Therefore, as the actuators retract, the seat assembly is moved in six degrees of freedom such as heave, sway, surge, pitch, roll and yaw. Audiences sitting on the seat assembly feel excited and experience a real virtual reality. Moreover, the actuators bear axial force such as drag force and thrust force and are endurable and safety.07-22-2010

20100085784Ripple Voltage Suppression Method for DC/DC Converter and Apparatus Thereof - A ripple voltage suppression apparatus includes a DC/DC converter and a control circuit. The DC/DC converter has a power electronic switch. The control circuit has a voltage detector detecting a DC output voltage of the DC/DC converter, a ripple voltage suppression circuit receiving the detected DC output voltage to generate an AC control signal for controlling an AC component of a duty ratio of the power electronic switch, an output voltage regulation circuit receiving the detected DC output voltage to generate a DC control signal for controlling an DC component of a duty ratio, an adder adding the AC and DC control signals to form a combined control signal, and a PWM circuit converting the combined control signal into a PWM signal to control the power electronic switch. Only the DC output voltage of the DC/DC converter has to be detected for the control circuit.04-08-2010
20100254170DC to AC inverter - A DC to AC inverter has a DC power input port, a buck converter, a buck/boost converter, an output filter and an AC output port. The DC power input port has a positive input terminal and a negative input terminal, both connected to a DC source. The AC output port is connected to a single-phase utility system. When the single-phase utility system is in positive half cycle, the buck converter generates a positive half-cycle signal of sinusoidal current. When the single-phase utility system is in negative half cycle, the buck/boost converter generates a negative half-cycle signal of sinusoidal current. In either the positive or negative half cycles, only one power electronic switch is switched in high frequency to reduce switching loss. Further, the negative input terminal of the DC power input port of the invention can be connected to a neutral line of the single-phase utility system.10-07-2010

20100302769LAMP - A lamp includes a substrate having first and second sides. At least one lighting element is mounted on the first side. An air-guiding member is mounted to the substrate. An airflow chamber is formed between the air-guiding member and the second side of the substrate. The air-guiding member includes a plurality of air-guiding holes in communication with the air-guiding chamber. A plurality of heat-dissipating fans is respectively mounted to the air-guiding holes. A control unit is electrically connected to the heat-dissipating fans. The control unit controls operation timing and operation modes of the heat-dissipating fans so that the lamp has a plurality of heat-dissipating modes.12-02-2010
20110013419LINEAR LIGHT GUIDING MODULE - A linear light guiding module is provided, which includes a linear light guiding body, a plurality of light emitting bodies, a plurality of heat sinks, and a plurality of fans. With the linear light guiding body, the light emitting bodies, and the heat sinks linearly arranged, or with the fans further integrated, the linear light guiding module of the present invention has a small size and an effective heat-dissipation effect. Since only one linear light guiding module needs to be disposed on one side of a light guide plate, the linear light guiding module can be used in large-sized liquid crystal display panels. Moreover, the number of the linear light guiding modules used is decreased while the requirements for high brightness and brightness uniformity can still be met, so the cost can be reduced.01-20-2011
20110085342HEAT DISSIPATING DEVICE FOR LIGHTING MODULE - A heat dissipating device for a lighting module includes a frame having connecting portions and assembling portions each interconnected between two adjacent connecting portions. Each end of each connecting portion is connected to an adjacent assembling portion. A plurality of air-guiding members is located on the same side of the frame and each mounted on one of the connecting portions. Each air-guiding member includes an air guiding channel having an opening in each end thereof. Each of several heat dissipating fans is mounted to one of the assembling portions and located between two adjacent openings respectively of two adjacent air-guiding members. Each heat dissipating fan includes a first air guiding hole in communication with an environment and at least one second air guiding hole in communication with the two adjacent openings. The air guiding channels and the heat dissipating fans together form a cycling air channel.04-14-2011

20100208478AUTOMOTIVE HEADLIGHT SYSTEM AND ADAPTIVE AUTOMOTIVE HEADLIGHT SYSTEM WITH INSTANT CONTROL AND COMPENSATION - An automotive headlight system and an adaptive automotive headlight system with instant compensation control are provided. The automotive headlight system includes a light source, a total internal reflection prism, a digital reflecting element, a freeform lens, and a multi-curve-reflector. The total internal reflection prism is used for redirecting and reflecting light beams from the light source. The digital reflecting element is controlled to switch to a plurality of states with regard to reflected light beams from the total internal reflection prism then compensation patterns will be promptly given during different states. The freeform lens is used for controlling directions of the light beams from the digital reflecting element. The multi-curve-reflector has a plurality of radii of curvature for reflecting the light beams from the freeform lens. As the automotive headlight system merely uses optical refractive and reflecting elements so that the number of components and cost is greatly reduced as compared with the prior art. Furthermore, the most important is that this invention proposes a new design and instant and personalized compensation solution to reduce more driver's risks.08-19-2010

20110278739Semiconductor Package - The present invention relates to a semiconductor package. The semiconductor package includes a substrate, a first chip and an interposer. The first chip is mechanically and electrically connected to the substrate. Some signal pads of the interposer are capacitively coupled to some signal pads of the first chip, so as to provide proximity communication between the first chip and the interposer. Whereby, the capacitively coupled signal pads can be made in fine pitch, and therefore the size of the semiconductor package is reduced and the density of the signal pads is increased.11-17-2011
