Abstract: There is provided a method of improving a measurement of the flow velocity of blood in a blood vessel of a subject, the method comprising using an ultrasound transducer to emit an ultrasound beam to measure flow velocity in a part of a body of a subject; forming a spatial time velocity profile for the part of the body from the measured flow velocity; and analyzing the spatial time velocity profile to determine a correction to the angle of the ultrasound beam with respect to the subject, the correction being based on a difference between the position of a peak in the spatial time velocity profile and the center of the spatial time velocity profile.

Abstract: A device (10, 10′, 10″) includes a light source (12) and a light detector (14) spaced from, and in communication with, the light source (12). An electronic processor (18) is programmed to compute pulse oximetry data from output of the light detector (14). A clamping member (26) is included, on or in which the light source (12) and the light detector (14) are disposed. The clamping member (26) is configured for attachment to a human body part with the body part disposed between the light source (12) and the light detector (14) such that light from the light source (12) passes through the body part to reach the light detector (14). The clamping member (26) is configured to attach to the body part by transitioning from a first stable state to a second stable state via a compression force applied to the clamping member (26).

Abstract: A gas sensor system is for use in, or in the vicinity of, a toilet, for detecting a target gas. A gas sensor detects a concentration of at least the target gas and a further, reference, gas which is received from a controlled gas release device. These concentrations are processed to obtain a concentration of the target gas relative to the concentration of the further gas by combining a change in the detected concentration of the target gas, a change in the detected concentration of the further gas, the sensitivity of the gas sensor system to the target gas and the sensitivity of the gas sensor system to the further gas. This approach avoids the need for extensive calibration operations to tune the sensor response to the environment in which it is used.

Abstract: A remote photoplethysmography system includes a filter (10) for application to a detection unit. The filter further includes a first filter area (11) configured to transmit light (A) at a first wavelength and a second filter area (12) configured to transmit light (D) at a second wavelength. The detection unit (22) detects radiation received from the first filter area and from the second filter area of the filter. An analysis unit (6) determines the vital sign information of the subject from the detected radiation from the first filter area and from the second filter area.

Abstract: According to an aspect there is provided a method of determining the health of a subject, the method comprising determining the absolute humidity and volume of air exhaled by the subject over time; and analysing the determined absolute humidity and volume of air exhaled by the subject to determine a characteristic of the air that was above the isothermic saturation boundary, ISB, of the subject.

Abstract: An inductive sensing device comprises first (16) and second (24) loops, the first loop (16) being coupled with a capacitor to form a resonator circuit (20), and the resonator circuit and second loop being coupled via an active buffering component (28). The active buffering component provides voltage to current amplification, and an output of the buffering component drives a current in the second loop. Conductive lines forming each of the first and second loop parts are radially spaced apart.

Abstract: A system for monitoring blood distribution in a subject, the system comprising a processor(38) responsive to Doppler ultrasound data representing arterial blood flow in at least two different locations of the subject, such as the neck and the arm, to obtain velocity (C, B1, B2, B3) or volumetric flow rate at each location, to monitor changes in a predetermined function of the blood flows, and to provide an output indicative of the monitored changes which may result from blood volume centralization. This can indicate the onset of hypovolemia or hypervolemia.

Abstract: The capillary refill time (CRT) of a patient is an important feature in the determination of cardiovascular system health. Quick re-perfusion of the microcirculation (namely, the capillaries) is a good indication that the cardiovascular system is able to efficiently distribute blood throughout the body. Current systems use unreliable or subjective methods to test the CRT. Additionally, the calculation of CRT is not generally used in the adult medical space as it is more commonly used in pediatrics. The present application describes a system and method for calculating a patient's CRT using a mobile device with an integrated camera and light source, or an optical head-mounted display using a light source in combination with ambient light to calculate the CRT. Once a patient's CRT is calculated, an integrated application classifies the data and sends it to the treating clinician for review.

Abstract: Presented are concepts for monitoring cardio-respiratory function of a patient. One such concept comprises detecting light or sound from the sublingual vasculature using a sublingual sensor unit adapted to be positioned at a sublingual vasculature of the patient's tongue and to generate a sensor output signal based on the detected light or sound. A processing unit adapted to receive at least one of the sensor unit output signal, wherein the sensor unit and the processing unit are arranged to analyze the venous component in the sensor output signal. An output signal from the sublingual sensor may then be used to provide information on cardio-respiratory parameters like respiration rate and respiration rate variability, for example.

Abstract: An ultrasound controller unit (22) for controlling an ultrasound transducer unit (24) in acquiring ultrasound data for the purpose of deriving one or more physiological parameter measurements. The controller is adapted to control weighting coefficients applied to transmit and receive signals of each of a plurality of transducer elements (26) of the transducer unit. The controller is adapted to detect any artifact in received data affecting (e.g. obscuring) the output path of one or more of the transducers, and to identify the affected transducer elements. The weighting coefficients of the non-affected transducer elements are then adjusted so as to minimize an estimated noise component in the parameter measurement, if derived using only the non-affected transducer elements. Measurements of the one or more parameters are then derived by collecting data from the non-affected transducers only, these being configured with the optimized weighting coefficients.
