The present invention is a tethered resistance swim training apparatus with a pulley that includes an electronic tachometer to measure the rotations of the wheel of the pulley and strain gauge to measure the force pulling on the body of the pulley. The pulley, also referred to as “smart pulley”, can be implemented in many tethered swim training apparatuses of different arrangements. With the tachometer and strain gauge the power and other performance metrics can be calculated while a swimmer is using the apparatus. A load cell or similar can be used in place of a strain gauge. The sensors may be connected via wired or wireless communications to a computer (tablet, laptop, personal computer, server, or the like) for processing of the signals and display on an electronic display.

This invention is an inexpensive, easy-to-use, and easy-to-manufacture device that can be placed on the edge of a pool so that a swimmer can use it to count laps without significantly disrupting the swimming. The invention is lightweight and portable so that one person can carry it around, place it on the pool before swimming laps, and remove it afterwards.

An apparatus and method for measuring a swimmer's speed and conveying the speed to the swimmer in real time includes a plurality of ultrasonic beacons each having a transducer configured to emit ultrasonic signals in a pool or other body of water within which the swimmer is swimming. A wearable, waterproof, ultrasonic receiver worn by the swimmer, receives the ultrasonic signals and generates corresponding signal data. The receiver's microcontroller captures and uses the signal data to calculate the swimmer's position and speed in real time, and conveys this information to a wearable, waterproof, user interface device worn by the swimmer, the user interface device including a near-eye display disposed on the swimmer's goggles.

An exercise machine includes a frame which contains a flywheel which rotates around an axle coupled to spools. Original cords are wrapped around the spools and extend to upper pulleys on the frame. The original cords are coupled to adapter cords which extend to lower pulleys on the exercise machine. By pulling the adapter cords, the spools are rotated which causes the flywheel to spin. The adapter cords are released and springs retract the original cords so they can be pulled again. The lower pulleys lower the exit position of the adapter cords so that the exercise machine can be used with hand paddles to simulate swimming, paddle shafts to simulate paddling movements, exercise handles to simulate upper body functional exercises, or ankle straps to simulate lower body functional exercises.

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.
