Abstract: A bearingless split tooth flux-reversal motor (FRM) for use with a pump, such as a centrifugal blood pump. In some embodiments, the motor has a magnet-free rotor and a magnetic configuration wherein the force generation is independent of the rotor angle, allowing for simple radial force generation using stator-fixed currents. The motor torque can be generated using commutated two-phase currents.

Abstract: An artificial intelligence-based system for contextual content delivery includes a server configured to provide, via a user device, a contextually aware user interface. The server is also configured to determine, via input device(s), user interaction event(s) corresponding to the contextually aware user interface. Further, the server is configured to determine, via a model, a context associated with determined user interaction event(s). In addition, the server is configured to generate and/or identify, via the model, contextual content(s) and response(s) of different media types associated with the determined user interaction event(s) based on the determined context. Further, the server is also configured to manipulate, via the model, the contextually aware user interface and provide, via the manipulated contextually aware user interface, the generated and/or identified contextual content(s) and response(s).

Abstract: A position sensor with six degrees of freedom (DoF) measurement capability may be used for position sensing of the rotor in a bearingless slice motor to enable active control. The sensor is designed to fit entirely under the rotor and operates by accessing the rotor bottom surface only, enabling packaging of the pump on the top of the rotor. The sensor has two parts; both operate using eddy currents. One of these parts measures the two radial DoF of the rotor. The other part measures the axial, angular rotation and tip/tilt DoF. The sensor utilizes a conductive target fixed to the underside of the rotor. The design and fabrication of the sensor along with the signal processing methods are described.
