Abstract:

Inductive heating systems and method of controlling the same to reduce biological carryover are disclosed herein. An example system includes an induction heater including a tank circuit, the tank circuit including a work coil and a sense coil. The sense coil is to detect a magnetic field generated by the work coil and to output signals in response to the detection. The example system includes a controller to cause the tank circuit to oscillate at a resonant frequency in response to the signals and a power drive unit in communication with the controller and the induction heater. The power drive unit is to adjust power provided to the induction heater in response to the controller driving the tank circuit to oscillate at the resonant frequency.

John Robinson - Gurnee IL, US

International Classification:

C12Q 1/6853

Abstract:

Integrated devices that include a sample preparation component integrated with a detection component are disclosed. The sample preparation component may be a digital microfluidics module or a surface acoustic wave module which modules are used for combing a sample droplet with a reagent droplet and for performing additional sample preparation step leading to a droplet that contains beads/particles/labels that indicate presence or absence of an analyte of interest in the sample. The beads/particles/labels may be detected by moving the droplet to the detection component of the device, which detection component includes an array of wells. The detection modules disclosed here can be used for detecting analytes of interest which analytes may have been enriched by amplification, isolation, or other techniques.

Abstract:

Inductive heating systems and method of controlling the same to reduce biological carryover are disclosed herein. An example system includes an induction heater including a tank circuit. The example system includes a controller to drive the tank circuit to selectively oscillate at a resonant frequency for the tank circuit to inductively heat a work piece disposed proximate to the tank circuit.
