Abstract: The present invention relates to a novel method for producing astaxanthin by using microalgae. The method comprises: heterotrophic cultivation of microalgae, dilution, photo-induction, collection of microalgal cells, and extraction of astaxanthin. The method according to the present invention takes full advantages of rapid growth rate in the heterotrophic stage and fast accumulation of astaxanthin in the photo-induction stage by using a large amount of microalgal cells obtained in the heterotrophic cultivation stage, so as to greatly improve the astaxanthin production rate and thereby achieve low cost, high efficiency, large scale production of astaxanthin by using microalgae. The method not only provides an important technical means to address the large scale industrial production of astaxanthin through microalgae but also ensures an ample source of raw material for the widespread utilization of astaxanthin.

Abstract: A crosswise adjustable wheel system (5) for a vehicle (1) having at least two wheels (3). The crosswise adjustable wheel system (5) has a wheel (7), an axle (11), at least one sleeve (20), and an adjustment system (4). The wheel (7) has a receiver part (10?), one end of the axle (11) connects to the receiver part (10?) of the wheel (7), near the end (10) of the axle (11), a universal axle (14) may be used while the crosswise adjustable wheel system (5) been used in front of a vehicle (1), several connect parts (18) disposed on the sleeve (20) to fix-the wheel system (5) on to a vehicle (1) with an angle (23), between the wheel (7) and ground (21) has a distance (22) on natural position (8), while the wheel (7) been pulled slant out to support position (9), the wheel (7) touched ground (21) due to the angle.

Abstract: A easy stand bicycle, motor-cycle, scooter, or electric-bicycle include a regular one of them, and at least two adjustable wheels with control system attached on them, so that, rider does not need standing on ground to support them on stop position. Also, main parts of a motor-cycle, scooter, or electric-bicycle with a car alike body can be made in a two wheels car, at least two adjustable wheels attached on the car, so that, rider can adjusts the adjustable wheels to support the car on stop position, and balance/support the car while making a turn.

Abstract: A system and method for updating a computer program on a mobile computing device comprises uploading of packages to a repository, wherein each package comprises update data for a different portion of the computer program, a server identifying portions of the computer program to be updated on a device based on comparing information reported by the device and metadata about packages in the repository and a download server configured to wirelessly download the packages to the mobile computing device. The device may report back installation status to a server.

Abstract: A self watering legged sheet includes a flat board, a plurality of leg, the legs extending downwardly from/or connecting to the flat board, the legs have a side wall, the shape of the flat board and the legs can be vary, a plurality of air vent hole disposed on the board. Further, a bottom wall may be dispose on each leg, at least one hole disposed on the bottom wall or on the side wall of the leg near the bottom wall, at least one connecting part disposed on the side of the sheet. Furthermore, the sheet having a side wall extending upwardly from side of the flat board, at least one connecting part disposed on the side wall. Yet, a movable connecting part can be used instead of the fixed connecting part either on the side of the flat board or on the side wall.

Abstract: Aerated plant pots having a side wall and a bottom wall, at least one hole disposed on the bottom wall of the pot, at least one aeration tunnel extending upwardly from bottom wall of the pot, the at least one aeration tunnel having side wall(s) or/and a top wall, a plurality of holes/slots disposed on the wall(s) of the aeration tunnel, the shape of the aeration tunnel may be vary and may extending to side wall of the pot and without end wall, at least one air chennel may be applied for more air flows in/out the aeration tunnel. The aeration tunnel may be used in self watering pot apparatus. The aerated plant pot further comprising a tray while the aerated plant pot is used inside of building.
