Device and method for monitoring muscular activity
First Claim
1. An apparatus for detecting electromyographic signals and monitoring muscle activity, said apparatus comprising:
- a sensor, for detecting the electromyographic signals,processing means, which, if the electromyographic signals exceed an activation value, then apply an integration algorithm or a frequency transformation algorithm to the detected electromyographic signals, and determine whether the integrated or frequency transformed signals are above a predetermined power content within a first predetermined time window and wherein an event signal is generated if the integrated or frequency transformed electromyographic signals are above the predetermined power content for at least a number of times within a second predetermined time window and wherein the event signal triggers an event, and,first communication means, for transmitting the detected electromyographic signals from the sensor to the processing means.

Abstract
An apparatus and a method for monitoring muscle activity are provided. The apparatus comprises a sensor for detecting the generated electromyographic signals and processing means. The processing means generates an event signal if the electromyographic signal exceeds a predetermined power content within a predetermined time window. The event signal triggers an event, which may be an alarm. The apparatus further comprises communication means for transmitting the detected electromyographic signals from the sensor to the processing means. The means comprises the steps of detecting and evaluating the electromyographic signals. Furthermore, the method comprises generating an event signal and triggering an event by the event signal.
