  • Patent number: 10336223
    Abstract: A ventilation seat for a vehicle is provided. The ventilation seat is configured such that a through channel to directly discharge air is formed in a seat pad so that air supplied from an air supply unit is discharged over the seat pad through the through channel, whereby the through channel or the like can be prevented from becoming narrow or being blocked due to the weight of an occupant, resulting in increased or maximize air discharge rate.

  • Publication number: 20190184868
    Abstract: A bi-directional blower includes a blower body for guiding for air to flow along an entire circumference scroll shape of an inner space of the blower body. The blower body divides the inner space into an upward space and a downward space to guide air flow. The blower body comprises: an upper discharge case discharging the air flow along the entire circumference scroll shape toward the upward space through an upper discharge port; and a lower discharge case discharging the air flow along the entire circumference scroll shape toward the downward space through a lower discharge port.

  • Patent number: 8748180
    Abstract: A microfluidic device for culturing cells, termed a microscale cell culture analog (?CCA), is provided. The microfluidic device allows multiple cell or tissue types to be cultured in a physiologically relevant environment, facilitates high-throughput operation and can be used for drug discovery. The microfluidic device uses gravity-induced fluidic flow, eliminating the need for a pump and preventing formation of air bubbles. Reciprocating motion between a pair of connected reservoirs is used to effect the gravity-induced flow in microfluidic channels. Bacterial contamination is reduced and high throughput enabled by eliminating a pump. The microfluidic device integrates a pharmacokinetic-pharmacodynamic (PK-PD) model to enable PK-PD analyses on-chip. This combined in vitro/in silico system enables prediction of drug toxicity in a more realistic manner than conventional in vitro systems.

  • Patent number: 8574639
    Abstract: The present invention relates to a method for preparing a fermented ginseng concentrate. The method first involves subjecting ginseng to an extraction with a solvent to obtain a ginseng extract. Next, pectinase and beta-galactosidase are added to the ginseng extract under conditions effective to ferment the ginseng extract. The fermented extract is then concentrated to produce a fermented ginseng concentrate. The method may further involve drying the fermented ginseng concentrate to obtain fermented ginseng powder. Combinations of the invention ginseng materials with other active and/or inactive materials are also disclosed.

  • Publication number: 20130157360
    Abstract: Three-dimensional biomimetic tissue scaffolds, as well as methods of manufacture of these scaffolds. The method is fully customizable to create a biomimetic tissue scaffold with shapes, densities, and geometries similar or identical to the tissue it imitates. For example, physiologically realistic collagen/PEG villi created using the method are designed to have a high-aspect ratio and curvature similar to villi found in the human small intestine. Accordingly, the biomimetic tissue scaffolds serve as an improved in vitro model for a wide variety of physiological research, as well as pharmacological testing and drug, compound, and/or metabolite uptake by cells growing on the scaffold, among many other uses.
