Abstract: A configurable amplifier circuit for a karaoke player is described. In one embodiment, a karaoke player includes: a DVD/CD reader port for coupling to a DVD/CD reader, a microphone input to receive audio signals from an external microphone, an MPEG decoder coupled to the DVD/CD reader port and the microphone input, the MPEG decoder having first and second output terminals, a processor coupled to the MPEG decoder, the processor to control the MPEG decoder, and a configurable amplifier coupled to the first and second output terminals, wherein a first audio signal originating from the first output terminal is selectively amplified by the configurable amplifier circuit in accordance with a second signal originating from the second output terminal.

Abstract: A computer-implemented process provides for intercepting a request from a management tool running on a management system. The request can be for a management tool to run on a managed system. Plural virtual consoles are created for the managed system. The original request is modified to generate a modified request that specifies that plural data types generated by said management tool are to be directed to different respective ones of said virtual consoles.

Abstract: The invention generally relates to droplet based digital PCR and methods for analyzing a target nucleic acid using the same. In certain embodiments, methods of the invention involve forming sample droplets containing, on average, a single target nucleic acid, amplifying the target in the droplets, excluding droplets containing amplicon from the target and amplicon from a variant of the target, and analyzing target amplicons.

Abstract: The invention provides methods for assessing one or more predetermined characteristics or properties of a microfluidic droplet within a microfluidic channel, and regulating one or more fluid flow rates within that channel to selectively alter the predetermined microdroplet characteristic or property using a feedback control.

Abstract: A system for transferring and/or concentrating a sample is provided. The system includes a chamber with a membrane brave positioned within the chamber. An electrode assembly is configured to create an electric field across the membrane to move a charged sample through the chamber such that the sample collects and may concentrate on the membrane. The system may include a plurality of membranes. The system may also include a plurality of microchannels outwardly extending from the channel, where the membrane extends along the plurality of microchannels. Aspects of the invention are also directed to a pipette which may be used to transfer and concentrate a sample on a membrane. Certain embodiments are directed to methods and systems for concentrating a nucleic acid sample.

Abstract: A Web browser (210) is configured to run in a middle compartment (206) of a Compartmented Mode Workstation (CMW) (200). The operation of the Web browser (210) is prevented from accessing or damaging other compartments of the CMW machine (200) as a result of mandatory access control (MAC), which is configured appropriately. The Web browser (210) communicates with Web servers (252) attached to the internet (240), the Internet being connected to an outside compartment of the CMW machine (210), via a trusted outside process (TPO) (214). TPO (214) has the privileges required to override MAC. The Web browser (210) communicates with a display server (232), which is attached to an inside compartment (204) of the CMW machine (210), via a trusted inside process (TPI) (204). TPI also has privileges to override MAC. The Web browser (210) can request and receive Web pages incorporating mobile code, and can process the mobile code safely within the middle compartment (206).
