Abstract: A device (100) having a proximal end (20) and end a distal end (40) for withdrawal of a liquid sample, fractionation, and separation of one or more fractions comprising: a piston assembly (300) comprising a piston (302) dismountably attached at its proximal end (20) to an actuating rod (350); a container (200) having a body (202) disposed with a cylindrical chamber (204) for slidable movement of the piston (302) therein; wherein the cylindrical chamber (204) is provided at the distal end (40) with a resealable septum (410) for co-operation with a puncture needle assembly (600) for withdrawal of the liquid sample, an at the proximal end (20) with a stop member (206), which stop member (206) limits movement of the piston (300) in a proximal direction, wherein the container body (202) is dimensioned to fit inside a centrifuge rotor, and is configured for breakability into two parts at a temperature of 0 deg C. or lower at a breakable zone (210).

Abstract: An active interface device including a transducer or sensor array having a plurality of transducers or sensors arranged to transform a cell activity into an electrical signal, at least one detection unit for detecting the electrical signal(s), at least one recording unit for recording the electrical signal(s), comprising a plurality of recording channels arranged for being routed to the transducers or sensors, and at least one control unit. The control unit is arranged for addressing the transducers or sensors to the detection unit(s), for activating transducers or sensors, and for routing the recording channels to activated transducers or sensors.

Abstract: The present invention relates to a large time constant steering circuit for slowly changing a voltage on a node between at least two discrete voltage levels. The present invention further relates to a slow steering current DAC comprising said large time constant steering circuit. The present invention further relates to an instrumentation amplifier device comprising a current balancing instrumentation amplifier for amplifying an input signal to an amplified output signal and a DC servo-loop for removing a DC-component from the input signal. The present invention further relates to an EEG acquisition ASIC comprising said instrumentation amplifier device.

Abstract: A circuit and method for providing a digital output indicative of the time at which an event occurred is disclosed. In one aspect, the circuit includes a fine timing circuit configured to determine in which sub-interval of a clock period the event occurred, and a correction circuit configured to correct an erroneous offset between a first and second clock signals in the fine timing circuit. The correction circuit includes a synch circuit configured to determine in which half of the clock period the event occurred so as to correct for erroneous offset in the fine timing circuit.
