Abstract: A foldable tricycle includes a center frame, a front frame to which a front wheel is rotatably attached, a rear frame to which two rear wheels are rotatably attached, and a four-bar link including a first bar that is integrated with the front frame, a second bar that is integrated with the center frame, a third bar that is integrated with the rear frame, and a fourth bar. The fourth bar has a shape of plates and covers the other bars while the link operates between an unfolded position and a folded position. Lockers that locks the link in either the unfolded position or the folded position are provided and include a pin, two recesses that receives the pin, and a tension spring that presses the pin into the recesses. A semi-circle guide guides the pin between the two positions and also covers the third bar.

Abstract: A micromirror array lens consists of many micromirrors with one degree of freedom rotation and one degree of freedom translation and actuating components. As a reflective variable focal length lens, the array of micromirrors makes all lights scattered from one point of an object have the same periodic phase and converge at one point of image plane. As operational methods for the lens, the actuating components control the positions of micromirrors electrostatically and/or electromagnetically. The optical efficiency of the micromirror array lens is increased by locating a mechanical structure upholding micromirrors and the actuating components under micromirrors. The known semiconductor microelectronics technologies can remove the loss in effective reflective area due to electrode pads and wires. The lens can correct aberration by controlling each micromirror independently. Independent control of each micromirror is possible by known semiconductor microelectronics technologies.

Abstract: A barbecue grill comprises a gridiron disk, a shaft extending from the gridiron disk so that the shaft becomes substantially perpendicular to the gridiron disk, a bowl having a channel where the shaft is detachably received through the channel, and a motor attached to the bowl to generate rotation of the shaft.

Abstract: Disclosed is a constant discharge structure for a nozzle head lowering type vacuum cosmetics container for containing high functional cosmetics. The constant discharge structure includes a liquid collecting chamber having a liquid inflow hole in the lower portion of a piston support member mounted in the container, a groove having an inclined short jaw, a support jaw and a liquid inlet hole and an open/close unit for opening/closing the liquid inflow hole in the lower portion of a central shaft, an elastic pumping member being inserted into the groove of the shaft and including a hole having an inner wall for opening/closing the liquid inlet hole on a flat surface unit, and a cylinder incorporated inside a piston for supporting the central shaft.

Abstract: A method for making a fabric having a ground and pile threads inserted between the ground threads is provided. The method comprises a step of weaving two fabrics simultaneously so that the fabrics are positioned parallel and spaced by a predetermined distance, and the pile threads are inserted alternately between the ground threads of one fabric and between those of the other fabric. Also, each pile thread is wound around one of the ground threads by one or more turns. The method further comprises cutting the pile threads between the fabrics, and heat setting the fabrics to bind the pile threads to the ground firmly. The pile threads are made of acrylic yarn, and the weight percentage of the pile threads in the fabric is between 80 and ninety-five 95, and the weight percentage of the ground threads in the fabric is the remainder.

Abstract: A vehicle safety system for preventing inadvertent acceleration of a vehicle by a driver is provided. The vehicle includes an engine that supplies power to move the vehicle, a transmission that transmits power from the engine to wheels of the vehicle, an acceleration module that controls the engine to increase power, and a brake module that slows down or stop the vehicle. The acceleration module includes an accelerator pedal that receives pressure applied by the driver, and the brake module includes a brake pedal that receives pressure applied by the driver. The system includes a pressure sensor that senses pressure applied to the accelerator pedal, and a control circuit that is connected to the pressure sensor and the vehicle. The control circuit is activated to prevent inadvertent acceleration of the vehicle when the pressure sensed by the pressure sensor exceeds a predetermined safety threshold.

Abstract: An enhanced bass drum pedal is provided with an eccentricity-adjustable cam system comprising a cam core mounted on a rotating shaft, a cam member rotatably connected to the cam core by a first pin, a positioning member rotatably connected to the cam member by a second pin, and a set screw. The positioning member is fastened onto the cam core by the set screw at a selected position of the positioning member to adjust the eccentricity of the cam system relative to the axis of rotation. As a result, a user can readily alter the impact force acted on a drum head and the restoring force applied to the foot board thereby tuning the bass drum pedal to suit the user's playing style and ability.

Abstract: The present invention relates to antibiotics, anti-inflammatory agents, antihyperlipidemia agents, antidiabetes agents and anticancer agents, of which medical treatment materials are extracted by hot water or organic solvent from 20-year (or older) perennial old platycodon (i.e., old platycodon) with various physiological effects, or selective mixture of these extracts and other allowable herbal medicines or herbal medicine extracts. The old platycodon extracts have further enhanced effects than conventional medicines or 2-4 year old common platycodon, in terms of antibiotic activity, lipid metabolism improving activity, blood glucose level lowering activity, inhibition activity against adhesion of cancer cells immunity increasing effect, anti-arthritis effect, etc.

Abstract: An automatic tablet dispensing and packaging system includes a tablet packaging unit and a tablet dropping unit that have door cabinets and slider cabinets. The packaging system comprises a front hopper for the door cabinets, and rear hoppers detachably mounted in the base plate to minimize the rebounding of the released tablets, and kinetic force of the tablets being dropped via the corresponding channel.
