A ground reaction force plate apparatus and measuring system are provided. The apparatus includes a plate for receiving a force to be measured as applied by a subject to the plate and a plurality of load cells in an arrangement supporting the plate, each load cell being a single-axis sensor with the axis provided at an angle to a plane of the plate and oriented towards a centre of the plate. The load cells are configured to measure data relating to a force vector at the angled single-axis sensor when the subject applies a force to the plate. A data collection controller is provided for logging time series measurements of the load cells over a time in which the subject applies a force to the plate. The system applies machine learning processing to output the load cell measurements as a three-dimensional ground reaction force on the plate by a subject.

A human body sensing mat for sensing the movement of a human body, comprises: a substrate; a sensor array including a plurality of fiber sensors for generating signals according to a distance to a specific object, and disposed on the substrate; and a driving unit for applying a voltage to the sensor array, wherein the sensor array includes a plurality of sensing lines arranged in parallel in a first direction, and regarding the plurality of sensing lines, a first distance between neighboring sensing lines connected to different electrodes is greater than a second distance between neighboring sensing lines connected to the same electrode. The human body sensing mat can analyze user's movements and biometric signals regardless of the user's posture.

In some embodiments, an electric field generator generates an electric field at a nominal frequency. A detector measures, at multiple time points during a measuring period, one or more properties of the generated electric field. In various embodiments, the one or more properties of the electric field change over time due to interactions with a human body in a reactive near-field region of the electric field. From the measured one or more properties, a computation unit determines one or more periodic behaviors (such as a respiration or heartbeat) and one or more non-periodic behaviors (such as movement of a limb). The computation unit also computes, from at least one of the periodic and non-periodic behaviors, one or more physiological parameters of the human body. From the one or more physiological parameters, the computation unit detects one or more symptoms of a condition of the human body.

The present invention relates to a method of operating a smart mattress system for preventing snoring which can stop snoring of a user, wherein an air mattress and an air pillow interlock with a user terminal so that a user can easily control the air mattress and the air pillow.

A pressure support system for providing pressure support therapy to a patient, the pressure support device includes an airflow generator structured to generate a flow of breathing gas to the patient, a temperature conditioning unit structured to adjust a temperature of the breathing gas provided to the patient, and a processing unit structured to estimate a core body temperature of the patient for selected times of day based on one or more inputs and to control the temperature conditioning unit to adjust temperature of the breathing provided to the patient at the selected times of day based on the estimated core body temperatures of the patient.

A body physiotherapy machine contains a conductive sphere member and a body configured to output electric physiotherapy energy to the conductive sphere member. The conductive sphere member is held by a user to contact his/her discomfort or acupuncture points so as to comfort the user and to enhance metabolism by ways of the electric physiotherapy energy, thus maintaining health easily.

The present disclosure provides methods and apparatus for evaluating tissue structure in damaged or healing tissue. The present disclosure also provides methods of identifying a patient at the onset of risk of pressure ulcer or at risk of the onset of pressure ulcer, and treating the patient with anatomy-specific clinical interventions selected, based on pressure measurements.
