A portable motorized centrifugal system is optimized for low cost manufacture and operation. Separation of inhomogeneous fluid biological samples, such as liquid plasma from whole blood, is a common step in medical diagnostic tests. This system may enable remote separation where access to plug-in power sources are limited. The system may facilitate at-home testing. Due to biohazard concerns, the entire centrifugal apparatus portable and disposable, or the system includes one or more disposable elements within the interior of the centrifuge. Alternatively, the system may contain a module of higher value components that are re-usable after disinfection. Devices and methods for implementing centrifugal separation may include disk-shaped fluidic cartridges and tubes with reduced drag cross-section.

A swing rotor assembly for a centrifuge. The swing rotor assembly includes a driving unit including a motor, a mounting cap on the motor, and a transmission charging module on the mounting cap to wirelessly charge the battery; a rotor header including a case in which U-shaped curved portions are formed for mounting a bucket while being mounted and rotated on a motor driving shaft, an angle maintaining unit mounted inside the case to control an angle of the bucket and discharge a centrifuged sample, a battery mounted inside the case to drive the angle maintaining unit, a reception charging module on the case to wirelessly charge the battery, and a rotation shaft unit inside the case and rotatably supported at both sides of the bucket; and a bucket on the rotation shaft unit and rotating up and down by a centrifugal force while rotating together with the rotor header.

A device for conversion of carbon dioxide to oxygen, includes, in order, an axial compressor, a centrifuge compressor, a drum, an air pump, and a housing which provides an accommodating space to house the above assemblies together. The axial compressor and centrifuge compressor inhale the carbon dioxide rich air into the accommodating space, then the carbon dioxide rich air pass through the surface of the reactor drum which cause the carbon dioxide bouncing between the reactor drum and the wall of the accommodating space, the collisions of the carbon dioxide molecules will bend and break the molecule bond between carbon and oxygen to produce oxygen. The device, as mentioned earlier, provides a solution to the greenhouse effect, which eliminates the carbon dioxide and generates oxygen by physical method, and advances a design to enhance the conversion process, which has the potential of being enlargement.

Embodiments of a portable and compact centrifugal system with methods of energy efficient centrifugation are described. The centrifugal system may be used to separate biological samples contained in conventional laboratory tubes and may be powered by a set of battery cells. The centrifugal system may comprise a vibration damping system which may comprise a tuned mass damper with a damper mass, a damper wall, and an elastic coupler. Many features such as the device's voltages, vibration damping methods, firmware, circuitry, component placement, and material required careful consideration, experimentation, and selection to converge into a functional product. Centrifugation of biological samples typically requires bulky instruments that cannot be readily moved, which can prove inconvenient for remote areas and third world countries. Biological sample quality also degrades outside the body over time, so immediate access to a centrifugal system can improve sample quality.

A sensor system includes a sensor element, a signal processing circuit, and a pseudo-signal correction circuit. The sensor element outputs an electric signal corresponding to an external force. The signal processing circuit converts the electric signal coming from the sensor element into a signal having a certain signal format and then outputs the signal thus converted. The pseudo-signal correction circuit corrects a pseudo-signal outputted by the sensor element. When receiving a test signal, the sensor element performs a self-diagnosis based on the test signal and then outputs the pseudo-signal, which represents a result of the self-diagnosis. The pseudo-signal correction circuit corrects the pseudo-signal based on environment information about an environment where at least one of the sensor element or the signal processing circuit is located.
