Abstract: A system is provided for determining the movement of an interventional device inside a lumen. The interventional device comprises a distal portion inside the lumen and a proximal portion outside the lumen and the system comprises a processor. The processor is configured to receive one or more images from an ultrasound transducer, wherein the images are representative of the lumen with the interventional device inside and input the one or more images into a machine learning algorithm.

Abstract: Described herein are systems and methods which utilize an array of wells to rapidly detect target analytes from whole blood samples, even at very low concentrations. The provided systems and methods dry the blood sample to ensure a fluidic network forms in one or more dry blood sample islands and liquid with reagents useful for detecting nucleic acid sequences from a target analyte, including by amplification reactions that are bi-phasic because of the interaction between the solid dried blood sample phase and the liquid phases, including liquid having reagents that are able to fluidically and diffusively exchange with the fluidic network within the dried blood sample phase.

Abstract: Methods, systems, computer-readable media, devices, and apparatuses for synchronized mode transitions are presented. A first device configured to be worn at an ear includes a processor configured to, in a first contextual mode, receive a first mode change request from a second device to transition at a first time to a second contextual mode. The first mode change request is based on detection of a trigger condition. The processor is further configured to, at the first time, transition from the first contextual mode to the second contextual mode based on the first mode change request.

Abstract: Methods, systems, computer-readable media, and apparatuses for audio signal processing are presented. A device for audio signal processing includes a memory configured to store audio data and a processor coupled to the memory. The processor is configured to use an adaptation filter to adapt update filter coefficients of an update filter. The update filter coefficients are adapted based on a difference between an internal microphone signal and an output of the adaptation filter. An input of the adaptation filter is based on an external microphone signal. The processor is also configured to output an output signal from a hear-through filter. The hear-through filter includes the update filter and the adaptation filter. The processor is further configured to cause a loudspeaker to produce an audio output signal based on the output signal of the hear-through filter.

Abstract: A torque transmission system (20) for transmitting torque from a prime mover (22) along a drivetrain includes a clutch device (28) configured to accept a torque input from the prime mover, an intermediate pulley (32), a belt (30) operatively engaged between the clutch device and the intermediate pulley, an angle gearbox (36) configured to change a spatial orientation of torque transmitted between an input and an output of the angle gearbox, a driveshaft (34) operably engaged between the intermediate pulley and the angle gearbox, and an output device (38) configured to accept a torque output from the angle gearbox. The clutch device is located upstream from the intermediate pulley and the angle gearbox along the drivetrain.
