  • Publication number: 20250233535
    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.

  • Publication number: 20170021356
    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.

  • Publication number: 20140087958
    Abstract: A honeycomb tube with a planar frame defining a fluidic path between a first planar surface and a second planar surface. A fluidic interface is located at one end of the planar frame. The fluidic interface has a fluidic inlet and fluidic outlet. The fluidic path further includes a well chamber having an well-substrate with a plurality of wells. The well chamber is arranged in the planar frame between the first or second surface and the well-substrate. The well chamber is in fluidic communication between the pre-amplification chamber and the fluidic outlet.
