Abstract: Thermal control devices adapted to provide improved control and efficiency in temperature cycling are provided herein. Such thermal control device can include a thermoelectric cooler controlled in coordination with another thermal manipulation device to control an opposing face of the thermoelectric cooler and/or a microenvironment. Some such thermal control devices include a first and second thermoelectric cooler separated by a thermal capacitor. The thermal control devices can be configured in a planar configuration with a means for thermally coupling with a planar reaction vessel of a sample analyzer for use in thermal cycling in a polymerase chain reaction of the fluid sample in the reaction vessel. Methods of thermal cycling using such a thermal control devices are also provided.

Abstract: Improved sub-assemblies and methods of control for use in a diagnostic assay system adapted to receive an assay cartridge are provided herein. Such sub-assemblies include: a brushless DC motor, a door opening/closing mechanism and cartridge loading mechanism, a syringe and valve drive mechanism assembly, a sonication horn, a thermal control device and optical detection/excitation device. Such systems can further include a communications unit configured to wirelessly communicate with a mobile device of a user so as to receive a user input relating to functionality of the system with respect to an assay cartridge received therein and relaying a diagnostic result relating to the assay cartridge to the mobile device.

Abstract: Thermal control devices and methods to provide improved control, speed and efficiency in temperature cycling are provided herein. Such thermal control device and methods can include one or more active elements, such a thermoelectric cooler device, that is controlled by an algorithm that regulates a temperature distribution of an adjacent reaction-vessel according to a temperature distribution command trajectory and estimated reaction-vessel temperature distribution. Some embodiments include two active elements that are bilaterally applied to opposing sides of the reaction-vessel. In some embodiments, the estimated reaction-vessel temperature is determined based on a state of power electronics of the element and a temperature output of one or more sensors of a portion of the element and/or an ambient environment of the reaction-vessel. Methods of calibration of such systems utilizing a thermal calibrator as a proxy for the reaction-vessel are also provided herein.
