Abstract: A microservice node can receive a request for information identifying a corrected physical location of a client device. The request can include raw satellite data associated with the client device. The microservice node can convert the raw satellite data to a Radio Technical Commission for Maritime Services (RTCM) format. The microservice node can determine, based on converting the raw satellite data to the RTCM format, an estimated physical location of the client device. The microservice node can receive, based on transmitting a request to a network real-time kinematics (RTK) device, corrections data associated with the estimated physical location of the client device. The microservice node can determine, using a cloud RTK engine, the corrected physical location of the client device based on the estimated physical location and corrections data. The microservice node can transmit, to the client device, the information identifying the corrected physical location of the client device.

Abstract: Adaptive respiratory condition assessment can include capturing signals generated by sensors of a portable device positioned to sense a user's body. The sensors can generate the signals in response to sensor-detected movements of the user's body measured along multiple axes and corresponding to lung activity in the user's body during respiratory cycles. A preferred axis of measurement can be selected using signal processing performed by a signal processor embedded in the portable device. Waveforms generated from signals corresponding to signals generated in response to movements of the user's body measured along the preferred axis can be filtered for extracting biomarkers from the waveforms using the signal processor. The one or more biomarkers extracted correspond to the lung activity. Based on the biomarkers, a respiratory condition of the user can be determined. A notification based on the respiratory condition as determined can be generated and conveyed with the portable device.

Abstract: A rotary electric machine includes a rotor and a stator. The stator has windings and teeth extending radially from a stator core. Each tooth is separated from an adjacent tooth by a stator slot that opens to a radial stator-rotor airgap via a slot opening. The windings are positioned within each slot. Each stator tooth has a tooth tip with a surface profile configured to guide rotor flux away from areas of the windings proximate the respective slot opening. The tip surface profile may be a concave region, e.g., a dent/chamfer, and/or a convex region, e.g., a bump/bulge, and is formed in a distal end surface of the tip proximate the opening. The stator-rotor airgap is smaller at the convex region and larger at the concave region than elsewhere along the distal end surface. An electrical system includes the machine, a battery, and a power inverter module.
