The radiograph X-ray attenuation image acquisition unit is configured to acquire a radiograph image of a patient. The radiograph X-ray attenuation image acquisition unit is configured to provide the radiograph image to the processing unit. The at least one sensor is configured to acquire sensor data of the patient. The at least one sensor is configured to provide the sensor data to the processing unit. The processing unit is configured to determine a magnitude and direction of movement of the patient during a time of acquisition of the radiograph image, the determination comprising utilization of the sensor data. The processing unit is configured to post-process the radiograph image comprising utilization of the determined magnitude and direction of movement of the patient during the time of acquisition of the radiograph image.

A system and method for prompting a patient experiencing ventilatory depression to breathe includes at least one sensor for detecting ventilatory depression by detecting inadequate breathing or lack of breathing in the patient. The system also includes one or more sensors for determining the type of breathing problem experienced by the patient. A sensor for detecting motion of the patient is used to determine whether the patient is moving. If inadequate or a lack of breathing is detected and the patient is not moving, the system provides verbal prompts or tactile stimuli to prompt the patient to breathe to improve patient ventilation.

A signal measurement method and a signal measurement apparatus (1000) are provided. A mode selection switch (11) may be used to enable a multi-lead measurement mode, to obtain signals of a plurality of leads and a status of a user. When quality of the signals of the plurality of leads is good or the user is in a static state, extracted features of the signals of the plurality of leads are output. When the signals of the plurality of leads are poor and the user is in a moving state, the mode selection switch (11) is used to switch to a single-lead mode with right leg drive, to obtain a signal of a single lead. A common-mode signal is eliminated from the signal of the single lead by using a negative feedback of a right leg drive electrode, and a feature of the signal of the single lead is output.

A medical imaging apparatus, and a sensor arrangement for acquiring at least one item of patient movement information during a medical imaging examination, have at least one sensor element and a support apparatus, with the at least one sensor element arranged on the support apparatus. The support apparatus has a positioning element for positioning the support apparatus and at least one strut-like support element on which the at least one sensor element is removably arranged.

The embodiments of the multifunctional telemetry apparatus to track emergency situations through analysis of tracking information even in moving conditions or victimizer based emergency situation without active inputs or active involvement from user. Classified clinical emergency and child tracking applications synchronized to the emergency support apparatus, and these applications operated by the life-support having classified trigger commands and tracking information displayed in a manner to help efficiently mitigate emergency risks. The apparatus configured through novel communication means to communicate to life-support network even with no access to standard communication channels.

A method for assessing movement of a body portion includes, via one or more machine learning models, analyzing a sensor signal indicative of movement of the body portion to determine a movement of the body portion; determining a sensor confidence level based, at least in part, on a characteristic of the sensor signal; receiving a series of images indicative of movement of the body portion; measuring an angle of movement of the body portion; determining a vision confidence level based, at least in part, on a quality of an identification the body portion; selecting the sensor signal, the measured angle of movement, or a combination thereof as an input into a machine learning model based on the sensor confidence level and the vision confidence level, respectively; analyzing the input to determine a movement pattern of the body portion; and outputting the movement pattern to a user.

Methods, apparatus, and systems relating to a Wearable Cardioverter Defibrillator (WCD) system capable of logging event data and/or broadcasting state changes and/or system status information to external clients are described. In an embodiment, a processor stores data corresponding to one or more event markers in memory in response to occurrence of an event. Occurrence of the event is detected based at least in part on detection of one or more parameters by one or more sensors or a signal to be generated by one or more of electrodes of the WCD system. A communication device transmits at least a portion of the stored data to a remote device. A patient condition or a WCD system condition can then be detected based at least in part on analysis of the stored data and/or the transmitted portion of the stored data. Other embodiments are also disclosed and/or claimed.

An ear-worn device includes a speaker, an optical emitter, an optical detector, a processor, and a housing configured to be positioned within an ear of a subject, wherein the housing encloses the speaker, optical emitter, optical detector, and processor. The housing includes at least one window that exposes the optical emitter and optical detector to the ear of the subject, and the housing includes at least one aperture through which sound from the speaker can pass. Light transmissive material is located between the optical emitter and the at least one window and is configured to deliver light emitted from the optical emitter to an ear region of the subject at one or more predetermined locations. Light transmissive material is positioned between the optical detector and the at least one window and is configured to collect light external to the housing and deliver the collected light to the optical detector.
