Patent number: 9404838Abstract: A particle manipulation system uses a MEMS-based, microfabricated particle manipulation device which has an inlet channel, output channels, and a movable member formed on a substrate. The movable member moves parallel to the fabrication plane, as does fluid flowing in the inlet channel. The movable member separates a target particle from the rest of the particles, diverting it into an output channel. However, at least one output channel is not parallel to the fabrication plane. The device may be used to separate a target particle from non-target material in a sample stream. The target particle may be, for example, a stem cell, zygote, a cancer cell, a T-cell, a component of blood, bacteria or DNA sample, for example.

Patent number: 9332967Abstract: An assay test device comprises a cup container having a detachable top cover that has a volume-reducing internal structure. A pocket shaped and dimensioned to nest a chromatographic test strip cartridge is mounted against a flattened transparent portion of the cup side wall. The cartridge is held in a vertical position with an aperture near the top edge of the cup. A splash shield projects for the brim region of the cup over that aperture preventing any part of the sample fluid poured into the cup from entering the cartridge and contacting the test strips prematurely. When the lid is installed and the cup flipped upside-down, the internally projecting structure raises the level of sample fluid for better access to the cartridge aperture. The structure can be adapted to extend all the way through the inside of the cup to contact its closed bottom. A central cavity in the structure having a open end captures a small volume of fluid and preserves it for later confirmatory analysis.Type: GrantFiled: April 16, 2009Date of Patent: May 10, 2016Assignee: Ameditech, Inc.Inventors: John Wu, WaiPing Ng

Patent number: 9335237Abstract: Systems and methods for processing tissue samples using acoustic energy. The tissue sample may be collected and placed on a substrate (e.g., microscope slide), or other sample holder. A transfer substrate may be positioned on the other side of the sample opposite the substrate. A microscope incorporated with the acoustic treatment system may be used to view, identify and select a portion of the sample to be transferred from the initial substrate to the transfer substrate. The selected portion of the sample is exposed to focused acoustic energy while disposed between the two substrates. The focused acoustic energy has characteristics (e.g., high frequency, small focal zone) that may be effective to transfer the selected portion of the sample from the initial substrate to the transfer substrate. Such transfer may occur with little to no damage to the sample, for example, at low temperature isothermal conditions and/or little to no cavitation of or around the sample.Type: GrantFiled: June 6, 2013Date of Patent: May 10, 2016Assignee: Covaris, Inc.Inventor: James A.

Patent number: 9335335Abstract: Provided is an automatic analyzer capable of detecting not only clogging and air suction of the dispensation probe but also a decrease in the dispensation quantity caused by a bubble film, air bubbles or a highly viscous sample. Each of a sample/reagent suction operation time and a sample/reagent discharge operation time of a probe is segmented into multiple time sections. For each of the time sections determined by the segmentation, a parameter is calculated by applying a detected pressure waveform to an approximation formula. For each of the time section, the presence/absence of a dispensation abnormality is judged by comparing the calculated parameter with a parameter in cases of normal dispensation. An automatic analyzer capable of judging the presence/absence of an abnormality specific to each time section and making abnormality judgments difficult for conventional techniques can be realized.Type: GrantFiled: July 11, 2013Date of Patent: May 10, 2016Assignee: Hitachi High-Technologies CorporationInventors: Tomonori Mimura, Kumiko Kamihara, Isao Yamazaki, Hideto Tamezane
