  • Publication number: 20230181068
    Abstract: An optical physiological sensor configured to perform high speed spectral sweep analysis of sample tissue being measured to non-invasively predict an analyte level of a patient. An emitter of the optical physiological sensor can be regulated to operate at different temperatures to emit radiation at different wavelengths. Variation in emitter drive current, duty cycle, and forward voltage can also be used to cause the emitter to emit a range of wavelengths. Informative spectral data can be obtained during the sweeping of specific wavelength regions of sample tissue.

  • Publication number: 20230019452
    Abstract: A method of determining blood pressure measurements includes inflating a cuff, receiving an indication of pressure inside the cuff during inflation, determining a blood pressure based at least in part on the received indication, assigning a confidence level to the blood pressure, and determining whether the confidence level satisfies a threshold confidence level. Based at least on a determination that the confidence level satisfies a threshold confidence level, the method can include causing a display to display the blood pressure. Based at least on a determination that the confidence level does not satisfy a threshold confidence level, the method can include deflating the cuff, receiving an indication of pressure inside the cuff during deflation, determining another blood pressure, and causing a display to display a blood pressure.

  • Patent number: 11515664
    Abstract: A magnetic connector has a plug core disposed around a plug contact set and a receptacle core disposed around a receptacle contact set. The plug core defines a generally elongated circular plug core edge. The receptacle core defines a generally elongated concentric-circular receptacle core edge. The receptacle core edge defines an air gap and the plug core defines an anchor configured to insert into the air gap. A coil is disposed around the receptacle core, and the coil, the plug core and the air gap define a magnetic circuit. The coil is electrically energized so as to form a magnetic field within an air gap, lock the anchor within the air gap and lock the plug contact set to the receptacle contact set accordingly.
