    Abstract: Continuous temperature monitors can be used to collect frequent temperature data over large periods of time. A machine learning system trained with collected temperature data can be used to predict future temperature data for patients. Such predictions can be clinically beneficial for disease states in which fever can be fatal, particularly for those fevers having fast onset. For example, patients undergoing chimeric antigen receptor T-cell (CAR-T) therapy may suffer fevers caused by cytokine release syndrome (CRS). Accordingly, a continuous temperature monitor is used to collect temperature data from CAR-T patients with high risk of CRS (or like patients with high fever risk), and the collected temperature data processed by a machine learning system to predict the patient's future temperature profiles. Results of analysis of the predicted temperature profiles may then be provided to the patient and/or clinician.

  • Publication number: 20210100469
    Abstract: Disclosed herein are methods, systems, and devices for identifying increased likelihood of non-ST elevation myocardial infarction (NSTEMI) in a patient based on ECG data. The methods can include determining based on the ECG data that the patient lacks ST elevation (STE) and that the patient exhibits a ventricular repolarization dispersion (VRD) score that exceeds a predetermined threshold value. The VRD score can be based in part on a T wave complexity ratio that serves as a temporal marker of VRD for the patient. Other markers of spatial and time qualities of repolarization can also be included in the VRD score. An elevated VRD score in the absence of STE can indicate a likelihood of NSTEMI in the patient and a potential major adverse cardiac event.

  • Publication number: 20210100489
    Abstract: Apparatus and methods are described for use with a seat (82) of a vehicle, including a sensor unit (80) configured to be placed underneath the seat and configured to detect motion of a subject who is sitting on the seat during motion of the vehicle. The sensor unit includes a housing (90, 100), a first motion sensor (96, 106) disposed within the housing such as to generate a first sensor signal that is indicative of the motion of the vehicle, and a second motion sensor (98, 108) disposed within the housing, such as to generate a second sensor signal that is indicative of the motion of the subject and the motion of the vehicle. A computer processor at least partially distinguishes between motion of the subject and motion of the vehicle by analyzing the first and second sensor signals. Other applications are also described.

  • Publication number: 20210100498
    Abstract: A system for determining a blood alcohol level of a subject may include a single light-emitting diode (LED) or, in some embodiments, two LEDs that may be operated in a pulsed mode and may illuminate a target location on a subject (e.g., a portion of a distal phalanx of a finger) with multiple illuminated light pulses. The system may include a photosensor that may sense multiple light pulses received from (e.g., reflected from, or transmitted through) the target location and generate multiple output signals. The system may include a controller that may determine a blood alcohol level of the subject based on the multiple output signals. Utilization of a single LED/two LEDs and operation thereof in a pulsed mode may prevent (or significantly reduce) heating of the LED(s) and/or the photosensor, thus eliminating a need in cooling units.
