Publication number: 20240076737Abstract: 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.Type: ApplicationFiled: August 7, 2023Publication date: March 7, 2024Inventors: Yuh-Min CHIANG, Doug Dority, Dustin Dickens, Jennifer Glass, Reuel Van Atta

Publication number: 20230421079Abstract: 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.Type: ApplicationFiled: June 26, 2023Publication date: December 28, 2023Inventors: Tien Phan, Doug Dority
