  • Patent number: 10496003
    Abstract: An exposure device includes an exposure section, a weight, and an elastic portion. The exposure section includes plural light emitting elements arranged along an axial direction of an image holding member that is rotatable, is positioned with respect to the image holding member at both ends in the axial direction, and exposes the image holding member to light by emitting light to the image holding member. The weight is disposed so as to face the exposure section, and has a mass determined in advance. The elastic portion is elastic, and is disposed between the exposure section and the weight to support the weight so as to be vibratable.

  • Patent number: 10227562
    Abstract: Motile particles are sorted from non-motile particles in a microfluidic sorting device wherein a stream of sort fluid containing motile and non-motile particles is caused to flow adjacent a media stream in non-turbulent fashion through a sort channel, during which flow motile particles cross the interface between the adjacent flow streams, entering the media stream, and forming a motile particle-depleted sort stream. The sorting devices are easily and inexpensively fabricated and have numerous uses, in particular sorting of motile from non-motile sperm.

  • Publication number: 20180164197
    Abstract: Disclosed is a method of isolating extracellular vesicles using an aqueous two-phase system (ATPS), including (a) preparing an ATPS by mixing a first material and a second material, which are immiscible with each other, with a body fluid or an aqueous solution containing extracellular vesicles and (b) isolating extracellular vesicles concentrated in the second material of the ATPS. This method can exhibit very high isolation efficiency, a simple isolation manner, and a very short isolation time. The isolation of extracellular vesicles using the ATPS requires no ultracentrifuge and achieves almost 100% isolation efficiency within a short time of about 10˜20 min, and thus the method of the invention is practical, is economical due to low costs thereof, can increase the purity of extracellular vesicles contaminated with protein, enables the diagnosis of disease using the isolated extracellular vesicles, and can be applied to various fields using extracellular vesicles.

  • Patent number: 8938095
    Abstract: A verification device 101 receives extracted and sanitized data 113 that has been sanitized to protect the privacy of person A. The verification device 101, extracts from among MCU-hash storage data 123 and for MCU1 and MCU2 among MCUs obtained by dividing the extracted and sanitized data 113, an MCU1 hash and an MCU2 hash. The verification device 101 generates an MCU3 hash to an MCU6 hash and from the MCU1 hash to the MCU6 hash, generates a JPEG frame hash 125. The verification device 101 then compares a JPEG hash 121 and the JPEG hash 125 to verify the authenticity of the extracted and sanitized data 113.
