A Controller and a Method to Determine a Swim Stroke: abstract simplified (18043152)

• This abstract for appeared for patent application number 18043152 Titled 'A Controller and a Method to Determine a Swim Stroke'

Simplified Explanation

The abstract describes a controller that receives input from an accelerometer and has various modules to process and analyze the input signal. The controller has an interface for input and output, a filter module to clean the input signal, and a stroke segmentation module to determine parameters and generate an envelope signal. The controller can then determine the swim stroke of a swimmer based on the filtered input signal and the envelope signal. Additionally, there is an activity detection module that works together with the stroke segmentation module.

Original Abstract Submitted

A controller is connected to receive an input signal from at least one accelerometer. The controller comprises an interface facilitating input and output pins/ports, and a filter module to filter the input signal from at least one accelerometer. The controller includes a stroke segmentation module configured to determine at least two parameters comprising a first parameter and a second parameter from the filtered input signal, generate an envelope signal using the at least two parameters and the filtered input signal, and determine the swim stroke of the swimmer based on the filtered input signal and the envelope signal. Further, an activity detection module is used in combination with the stroke segmentation module.
