A system may include a neuromodulator and a processing system. The neuromodulator may be configured to be programmed with a set of more than one program to deliver neuromodulation. The processing system may be configured to: receive sensed data indicative of activity, motion and/or posture of a patient; analyze the activity, motion and/or posture of the patient; and perform a process, based on the analyzed activity, motion and/or posture, for switching from one program in the set of more than one program to another program from the set of more than one program. The process may include automatically implementing the other program from the set of more than one program or suggesting to switch to the other program from the set of more than one program.

This disclosure relates generally to breathing analysis of a subject. Breathing analysis on a regular basis allows early detection for the onset of diseases, thus saving resources and cost in treatments. The existing state of art techniques require specialized devices to collect-infer the breathing and are mostly limited to analyzing breathing rate. The disclosure enables breathing analysis using a personal digital assistant (PDA). The breathing analysis includes (a) estimating exhale period-inhale period, (b) estimating the breathing rate and (c) determining the type of breathing. A PDA such as a smartphone is used receive accelerometer data from a subject. The received data is pre-processed in several steps including estimating a plurality of parameters, identifying a plurality of breathing cycles. The breathing cycles of the subject are further analyzed at real time based on the plurality of parameters to provide the breathing analysis of a subject.

A system, method and apparatus for capturing data from a plurality of users for providing online gameplay based on captured user sensor data. User sensor data is captured from a plurality of sensor capture devices relative to an associated user so as to be transmitted to a gameplay server. The gameplay server executes instructions to generate a user interface on a user's client computing device for providing gameplay on each user client portable computing device utilizing, and pertinent to, the captured sensor data.

Systems and methods for acquiring photoplethysmographic (PPG) signals for measuring blood pressure can include a computing device acquiring a sequence of images representing transdermal optical data of a subject, and generating a corresponding sequence of downsampled color frames. The computing device can identify, in each downsampled color frame, a respective central image block representing a central image region of the downsampled color frame and having a first size smaller than a second size of the downsampled color frame. The computing device can generate, for each downsampled color frame, a corresponding color intensity value based on the respective central image block. The computing device can generate, using color intensity values corresponding to the sequence of downsampled color frames, a PPG signal to determine a blood pressure value of the subject.
