    摘要： A spacecraft with a reaction wheel system can be autonomously safed by setting the solar wings to continuous tracking, determining a slew rate vector based on the total angular momentum, and slewing the spacecraft using the slew rate vector until commanded to stop autonomous safing. When the total angular momentum of the spacecraft to large to be handled by rotisserie, then the spacecraft is reoriented to align a suitable rotation vector with the system momentum. In a typical application, the spacecraft has a reaction wheel assembly with four wheels arranged to form a right regular pyramid. Two reaction wheels on opposite edges of the pyramid form a first pair and the two remaining reaction wheels forming a second pair. The slew axis of rotation is found by determining as a selected pair the first pair if either reaction wheel in the second pair is inoperative, otherwise determining as the selected pair the second pair and determining as the slew axis of rotation the normalized projection of the axes of rotation of the selected pair onto the base. The slew direction is determined by the sign of the total angular momentum component along the slew axis of rotation.

    摘要： A method and apparatus for determining the concentration of one or more microbes in a sample is provided. This method involves filtering a sample through a filter inside a sample tube to retain the one or more microbes on the filter. The resulting filtrate, which contains or produces adenosine triphosphate, is passed through the sample tube and enters the reporter region. In the reporter region, the adenosine triphosphate in the filtrate comes in contact with a transparent porous matrix, which includes a luciferin-luciferase complex. The adenosine triphosphate interacts with the luciferin-luciferase complex to provide light response, which is measured by a detector. The light response is compared with a calibration curve to determine the total concentration of one or more microbes in a sample.

    摘要： The Itch Blower is hand held, have a way to determine the distance from the skin. It blows hot air with the right temperature for eliminating the skin itching. Most importantly, it can sense the skin temperature remotely and shut off the heating automatically so to avoid burning. This will guarantee a smooth approval from the FDA and a great success in commercialization. The device eliminates skin itching completely in just seconds, no matter how bad the itching is, and keeps the itching away for up to 24 hours, and when the itching comes back, patients can use the device to quickly blow away the itching again, so to stay itching free. It can also clear up acne and eczema for some patients.

    摘要： For the purpose of preparing and isolating diamagnetic nanoparticles, we add magnetic field into the preparation processes, so that impurities that can be attracted to a magnet will go to the magnetic source. This enables diamagnetic nanoparticles get purified and contain no such impurities, so that they will be pushed away from the magnetic source.Some preparation processes use evaporation and condensation to prepare nanoparticles. In such processes, we may control the temperature so that lower evaporating metals, such as bismuth, will evaporate, but higher evaporating metals, such as iron, will stay solid and retain a strong magnetism, so that, when we apply magnetic field, we can prepare bismuth nanoparticles that do not contain lower evaporating metals for the preparation process.
