  • Patent number: 10984646
    Abstract: A fall detection system includes a plurality of sensors in which at least one of the sensors is coupled to or disposed near a floor. The fall detection system further includes a central monitoring system in signal communication with the plurality of sensors. The central monitoring system is configured to receive a response signal in response to an activation signal being transmitted from at least one of the plurality of sensors, and determine whether the response signal is indicative of a person being arranged in a prone position on the floor.

  • Publication number: 20210022620
    Abstract: In accordance with some embodiments, systems, methods, and media for estimating compensatory reserve and predicting hemodynamic decompensation using physiological data are provided. In some embodiments, a system for estimating compensatory reserve is provided, the system comprising: a processor programmed to: receive a blood pressure waveform of a subject; generate a first sample of the blood pressure waveform with a first duration; provide the sample as input to a trained CNN that was trained using samples of the first duration from blood pressure waveforms recorded from subjects while decreasing the subject's central blood volume, each sample being associated with a compensatory reserve metric; receive, from the trained CNN, a first compensatory reserve metric based on the first sample; and cause information indicative of remaining compensatory reserve to be presented.

  • Patent number: 10260947
    Abstract: A system and method of dynamically localizing a measurement of parameter characterizing tissue sample with waves produced by spectrometric system at multiple wavelengths and detected at a fixed location of the detector of the system. The parameter is calculated based on impulse response of the sample, reference data representing characteristics of material components of the sample, and path lengths through the sample corresponding to different wavelengths. Dynamic localization is effectuated by considering different portions of a curve representing the determined parameter, and provides for the formation of a spatial map of distribution of the parameter across the sample. Additional measurement of impulse response at multiple detectors facilitates determination of change of the measured parameter across the sample as a function of time.

  • Patent number: 10085679
    Abstract: A system and method for detecting vascular contamination by surgical anesthetic using non-invasive IR spectrophotometry. One embodiment is a method for operating an instrument such as an enhanced pulse oximeter to monitor a patient receiving local anesthetic marked with dye that absorbs infrared light. Light is applied to and detected from tissue of the patient. A signal representative of the detected light is processed to derive patient oxygenation information. The detected light is also processed to derive information representative of the presence of the dye-marked anesthetic. The oxygenation information and the information representative of the presence of anesthetic are displayed. The oxygenation monitoring and display and the anesthetic monitoring and display can occur separately or concurrently. Fluorescing dyes and fluorescence detection approaches are used for anesthetic detection in some embodiments.

  • Patent number: 9714900
    Abstract: A system and optimization algorithm for determining the preferred operational wavelengths of a device configured for measurement of molecular analytes in a sample. Operational wavelengths are determined by solving a system of equations linking empirically defined functions representative of these analytes, spectrally dependent coefficients corresponding to these analytes, path lengths traversed by waves probing the analytes at wavelengths corresponding to the absorption level described by the functions representative of these analytes, and, optionally, a cost-function taking into account at least one of spectral separation between the operational wavelengths, manufacturability of wave source(s) producing wave(s) at operational wavelength(s), and the noise factor associated with the operation of such wave source(s).

  • Patent number: 9635514
    Abstract: Method for identifying a location of a subject in a facility and a corresponding system including a kinematic sensor configured to detect a change in subject's mechanical characteristic, and a communications unit. Communications unit includes a controller configured to receive feedback from the kinematic sensor and a unit transceiver controlled by the controller to transmit a first radio frequency (RF) signal communicating the change. The system may include a housing facilitating coupling of the kinematic sensor with the subject, and at least one facility transceiver unit arranged in a fixed location to extract the first RF signal relative to an RF pattern and to produce an output signal. A processor is configured in communication with the facility transceiver unit (wirelessly or over the facility's power wire) to receive the output signal and to generate data representative of a location of the subject relative to the fixed location.
