Abstract:
1. A device for determining and displaying information about the repetitive movement of a swimmer's body, the device comprising: a sensor assembly comprising at least two static acceleration sensors configured to be mounted to the swimmer's back and including a first acceleration sensor positioned to track movement of the swimmer's body about a first axis that is substantially parallel to a direction of travel of the swimmer's body and a second acceleration sensor positioned on the swimmer's body to detect movement about a second axis that is substantially perpendicular to the first axis, and to generate at least first and second static acceleration signals when the swimmer is swimming; and a processor coupled to the sensor assembly and configured to determine at least one from among a stroke identification, a stroke count, a stroke pattern, a lap count, and a breathing pattern in response to only the at least one static acceleration signal and to provide a signal for display.
