Abstract: Techniques are disclosed for producing high quality losslessly compressed audio tracks based on conversations between participants remote from one another, such as conversations that occur during a telephonic interview or online conference, or other conversations that take place over a network between two or more participants. In an embodiment, each participant's device includes an audio chat client configured to record that participant's audio contribution to the conversation and store a non-compressed version of the contribution locally. A first version of the captured audio is generated with lossy compression and pushed in real time to a cloud-based service, for purposes of the live conversation. A second version of the captured audio for subsequent playback is generated and stored with lossless compression and is pushed asynchronously to the service. The service is configured to automatically provide a multitrack project with high quality audio tracks from each participant.

Abstract: A microvalve for controlling fluid flows, and a sealing device for sealing cavities in a microfluidic system, particularly in a lab-on-a-chip system, and a method for the production thereof. A sealing surface of a valve body, or a sealing element, respectively, rests on a sealing surface of a substrate and is pressed against the sealing surface of the substrate in a fluid-tight manner by means of a clamping element. The clamping element and/or the valve body, or the sealing element, respectively, are at least partially elastic.

Abstract: The present invention provides an integrated lab-on-a-chip device for carrying out a nucleic acid extraction process on a fluid sample containing cells and/or particles, the device comprising: (a) a sample inlet (1) for loading of a fluid sample, (b) a lysis unit (4) for lysis of cells and/or particles present in the fluid sample, (c) a reservoir of lysis fluid (7) for the lysis unit, (d) a nucleic acid extraction unit (5) downstream of the lysis unit, and (e) reservoirs of first washing buffer and eluant fluid (8, 9, 10) for the nucleic acid extraction unit, wherein the device further comprises (f) a mixing unit (6) downstream of the nucleic acid extraction unit, and (g) a source of mixing fluid (11) for the mixing unit. The reservoirs of lysis fluid, first washing buffer and eluant fluid may be provided parallel to one anther so that they may be actuated by a single pump.
