Publication number: 20180185837Abstract: A liquid-sample analyzer includes a housing that delimits an interior space and a recess adapted to receive a main body of a collection device that collects a liquid sample. When inserted into the recess, the main body extends longitudinally from the opening along a longitudinal axis of the collection device. The detection-and-analysis device is configured to detect and to analyze at least one representative parameter of the liquid sample. The locking-and-releasing retains the collection device in a locking position when the main body has been inserted into the recess. The releasing member exerts an ejection force on the main body toward the opening. The abutment portion contacts a bearing portion of the main body so as to immobilize the collection device while the main body is subjected to the ejection force.Type: ApplicationFiled: July 1, 2016Publication date: July 5, 2018Inventors: Patrick Pouteau, Vincent Poher, Paul Laurens

Publication number: 20110127405Abstract: This invention describes a device for optical stimulation of cells and other biological structures. It has an ability to target multiple cells and/or multiple sub-cellular targets. The stimulation optical pattern on each cell can be independently controlled with individual frequencies. The light sensitivity of the cells can be imparted as a result of genetic expression of surface and/or subsurface proteins, chemical modification of existing proteins, or via the release of caged entities which in turn act to stimulate the cell through chemical means. The embodiment is capable of functioning on neurons but can also be used for other cells. It can perform optimal stimulation with sub-cellular resolutions, record the activity of the targeted cells and perform processing to ensure calibration.Type: ApplicationFiled: May 18, 2009Publication date: June 2, 2011Inventors: Nir Grossman, Patrick Degenaar, Konstantin Nikolic, Mark Neil, Gordon Kennedy, Vincent Poher
