Abstract: A DC electric motor having a stator mounted to a substrate, the stator having a coil assembly having a magnetic core, a rotor mounted to the stator with permanent magnets distributed radially about the rotor, the permanent magnets extending beyond the magnetic core, and sensors mounted to the substrate adjacent the permanent magnets. During operation of the motor passage of the permanent magnets over the sensors produces a substantially sinusoidal signal of varying voltage substantially without noise and/or saturation, allowing an angular position of the rotor relative the substrate to be determined from linear portions of the sinusoidal signal without requiring use of an encoder or position sensors and without requiring noise-reduction or filtering of the signal.

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: Un motor eléctrico DC que tiene un estator montado a un sustrato, el estator tiene un montaje de bobina que tiene un núcleo magnético, un rotor montado al estator con imanes permanentes distribuidos radialmente alrededor del rotor, los imanes permanentes se extienden más allá del núcleo magnético y los sensores montados al sustrato adyacente a los imanes permanentes. Durante la operación del motor, el paso de los imanes permanentes sobre los sensores produce una señal sustancialmente sinusoidal de voltaje variable, sustancialmente sin ruido y/o saturación, permitiendo que se determine una posición angular del rotor con relación al sustrato, de las porciones lineales de la señal sinusoidal, sin requerir el uso de un codificador o sensores de la posición, y sin requerir una reducción del ruido o filtración de la se
