The invention provides a method for determining a transportation direction (TD) for a user, the method comprising: receiving a current location (CL) of the user; receiving a pollution based input value (PIV) related to air pollution in a geographical area (GA) including the current location (CL); determining the transportation direction (TD) using the pollution based input value such that the user is subjected to a lowest level of pollution and/or such that a predefined maximum level of pollution to which the user is subjected is not exceeded; and retrieving a human activity based input value, wherein the human activity based input value is based on activity data from a portable device (100) configured to sense an activity level of the human wearing the portable device (100); and updating the transportation direction (TD) using the human activity based input value (HAIV).

A non-invasive and convenient method and apparatus for approximation of left ventricular end diastolic pressure (LVEDP) can be used in both hospital/clinic environments and nursing home or home environments. The method and apparatus use non-invasive sensors and a new “cardiac triangle” computational method to obtain an approximation of LVEDP. The computational method uses hemodynamic and electrocardiogram (ECG) waveforms as input, which can be collected by a portable device or devices.

The present disclosure pertains to a system configured to determine one or more parameters of chest wall oscillation therapy for a subject. The system includes a wearable garment configured to provide percussion to one or more parts of a lung of a subject. The wearable garment includes: percussion excitation elements configured to produce the percussion; and sensors configured to generate output signals conveying information related to a response of the one or more parts of the lung to the percussion. The system includes a control unit configured to determine frequency and energy density information for the sounds made by the one or more parts of the lungs caused by the percussion, the frequency and energy density information determined based on the output signals; and determine the one or more parameters of the chest wall oscillation therapy based on the frequency and energy density information.

Described here are systems and methods for generating sound maps that depict the spatiotemporal distribution of sounds occurring within a subject. To this end, the sound maps may be four-dimensional (“4D”) maps that depict the three-dimensional spatial distribution of acoustic sources within a subject, and also the temporal evolution of sounds measured at those acoustic sources over a duration of time.
