Provided herein are devices and methods for use of a planar inductive resonant coupler comprising: a planar loop resonator comprising forming a single loop; wherein two or more dimensions of the planar loop resonator are sized to tune a coupler resonance in a gap that forms an inner perimeter of the planar loop resonator; and wherein the planar loop resonator is configured to establish electric fields across the gap and is configured to be coupled to circuitry, to receive or to transmit electromagnetic energy to or from a surrounding environment, and to transmit the electromagnetic energy to the circuitry.

Systems and methods for providing assistance to a surgeon during an implant surgery are disclosed. A method includes defining areas of interest in diagnostic data of a patient and defining a screw bone type based on the surgeon's input. Post defining the areas of interest, salient points are determined for the areas of interest. Successively, an XZ angle, an XY angle, and a position entry point for a screw are determined based on the salient points of the areas of interest. Successively, a maximum screw diameter and a length of the screw are determined based on the salient points. Thereafter, the screw is identified and suggested to the surgeon for usage during the implant surgery.

Systems and methods of detecting user vitals based on video stream data. The system includes a processor and a memory. The memory may store processor-executable instructions that, when executed, configure the processor to receive an image data set representing a user face over an evaluation period; generate a remote photoplethysmogram (PPG) signal based on the image data set; determine a recovered PPG signal by generating a frequency response based on a frequency-tuned filter bank and the remote PPG signal, the recovered PPG signal generated based on a peak wavelet magnitude of the frequency response; generate a predicted electrocardiogram (ECG) signal based on a prediction model where one or more prediction model decoders tuned based on semantic features of the prior identified remote PPG signal; and determine, for display at a user device, user vitals data associated with the evaluation period.

A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.

The disclosed technology includes a framework for an end effector of a medical device. The framework includes a base, a first cantilevered spine, a second cantilevered spine, and a first support. The base connects with an elongated shaft of the medical device. The first cantilevered spine extends from the base along a longitudinal axis to a terminal portion. The second cantilevered spine extends from the base along the longitudinal axis to a terminal portion. The first support connects the terminal portion of the first cantilevered spine with an intermediate portion of the second cantilevered spine.
