Techniques for patient pressure injury prevention (PPIP) include receiving, from a plurality of pressure sensors configured to be disposed in a spatial arrangement in contact with a patient, samples that indicate pressure measurements by the plurality of sensors at each of a plurality of different times. At each of the plurality of different times an angular orientation of the pressure is determined based on the samples. A change in the angular orientation of the pressure is determined at each successive time of the plurality of different times. A value of a patient movement parameter is determined based on the change in angular orientation of the pressure. A pressure injury category for the patient based on the value of the patient movement parameter is presented on a display device for a caregiver. Treatment of the patient by the caregiver is based on the pressure injury category.

A wearable device assembly has a housing supporting a controller, display and indicator system thereon. The controller has at least one sensor wherein activity of a user wearing the device is detected. The controller selectively illuminates the indicator system to indicate a level of activity of the user.

A wearable physiological measurement system may include, inter alia, sensors and circuitry for automatically and continually determining a heart rate of a wearer. The system can be charged while worn by the wearer via coupling with a removable modular housing, which may itself provide additional functionality such as a multi-function watch.

It is provided a fastening device for temporarily fastening a portable sensor device to a human body, the fastening device comprising: a device holder for releasably holding a portable sensor device configured to capture electrocardiogram signals and audio signals; a skin sealer configured to form an essentially airtight interface with a human body; and a bellows provided between the skin sealer and the device holder, the bellows, configured to fasten the fastening device to the human body using a suction effect after a portable sensor device held in the device holder is pushed towards the human body to let air escape from the bellows via the skin sealer.

Methods for automatically monitoring operation of a motion tracking system and actuating based on the operation, the motion tracking system comprising both a computing device, and a plurality of inertial measurement units adapted to be arranged on a body of a user. The computing device processes measurements of the units and sound captured by at least one microphone to provide flags related to the motion tracking procedure with regards to the motion input and the sound input, and actuates when motion-related flags and sound-related flags have been provided.

A system and method for continuous glucose monitoring (CGM) of blood in a blood vessel of a patient using a non-invasive sensor composed of a patch antenna operating in the Industrial, Scientific and Medical (ISM) Radio band (5.725 GHz-5.875 GHz). The device determines the blood glucose concentration of the blood in the blood vessel based on the measured shift of the resonant frequency of the non-invasive antenna patch sensor. A radio frequency (RF) synthesizer is used to drive the patch antenna with a fraction of its output coupled to both the antenna and receiver through a directional coupler. In this approach both the transmitted (FWD) and received (REV) power are processed, by demodulating logarithmic amplifiers, which convert the RF signals to corresponding voltages for downstream processing. The resulting voltages are then fed into a microcontroller and the measured shift in resonant frequency is converted to a real-time glucose concentration.

A tissue hydration monitor and method includes a sensor module having a plurality of LEDs positioned to emit a plurality of different wavelengths of light toward the user's skin and a detector that detects light transmitted and reflected through the user's skin to generate signals corresponding to an intensity of detected light at each of the different wavelengths. A processor/controller module generates a baseline hydration level based on the received signals, calculates a relative hydration level, and generates an output indicative of relative hydration personalized to the user. The housing is secured against the user's skin by an adhesive patch or a strap.

Various methods and systems are provided for selecting sensors for acquiring physiological data of a patient. In one embodiment, a system comprises a plurality of sensors, a dynamic selection switch communicatively coupled to the plurality of sensors, a plurality of acquisition channels communicatively coupled to the dynamic selection switch, and a processor communicatively coupled to the dynamic selection switch and configured with executable instructions in non-transitory memory that when executed cause the processor to: select a subset of sensors; control the dynamic selection switch to connect the subset of sensors to the plurality of acquisition channels; and acquire, from the subset of sensors via the plurality of acquisition channels, physiological data of a patient. In this way, a subset of sensors in a plurality of sensors may be dynamically selected in real-time for acquiring physiological data of the patient.

A method of conducting a procedure for a diagnosis of a portion of a patient's human musculoskeletal system, the method comprising a remediation recommendation method comprising the steps of: obtaining patient demographics, applying sensors above and below the joint, and then taking an image of the joint using a mobile device. Next, analyzing the image to determine bone centerlines, then instructing patient via a mobile device to perform a task involving assuming certain positions and performing certain movements, then the patient performing the task while the sensors record data about joint location and movement information. Next, using the data, image analysis and patent demographics to make a recommendation regarding joint ailment remediation.

A wearable device includes one or more sensors of information from a subject. The wearable device may have an electronic assembly supported by a base. The electronic assembly may include a sensor data collection system configured to control collection of sensor data related to one or more characteristics of a subject and one or more processors. the sensor data collection system may include a controller configured to control sequencing and scheduling of the sensor data collection, and a buffer configured to receive and buffer data corresponding to the sensor data collected from the one or more sensors in accordance with a signal provided by the controller. The one or more processors may be configured to receive the buffered data from the buffer in accordance with a wake signal; process the received data; and output the processed data. Scheduling and sequencing the sensor data collection by the sensor data collection system may be decoupled from the processor such that the processor may be in a low-power sleep mode during data collection and in a normal power mode to process data received from the buffer.
