Benefits of technology

The present invention is a new smart treadmill with some cool features. It allows the runner to automatically change the conveyor belt speed by putting their foot on or off the belt, without needing to manually adjust it. This makes the treadmill more realistic, as runners would be walking or running not in a fixed position. It also includes a two or three phase AC or BLDC motor, which is much faster and more energy efficient than standard DC motors. These motors enable real-time position sensing, obstacle detection, and emergency stops. The use of 3-phase AC or BLDC motors also improves energy efficiency. Overall, the new smart treadmill has improved user experience and is more efficient and safe.

Problems solved by technology

A previous invention involves the use of ultrasound distance measurement but the precision achieved was found not good enough for our application.

Embodiment Construction

[0020]Referring to FIG. 1 of the drawings and in accordance with the principles of the invention, the intelligent treadmill comprises a touch screen monitor (1), transmitter / receiver (2), motor (3), electronic drive (4), control panel (5), reflector (6) and three pairs of poles (7), (8) and (9).

[0021]The said touch screen monitor (1) is equipped with a pair of loudspeakers and a dimmable lamp, displaying the video of the surrounding environment of an outdoor track, downloaded from the Internet and a simple map showing runner current position.

[0022]The said transmitter / receiver (2) is for distance measurement, which emits and receives a laser beam to help estimate the exact distance of the reflector of the runner away from it.

[0023]The said motor (3) is a vectored controlled 2 / 3-phase AC or BLDC motor that adjusts the speed of the conveyor belt to fix the runner at a more or less constant distance from the transmitter / receiver or at a dynamically stable and stationary position on the...

Abstract

An intelligent treadmill is described with modifications to existing treadmills, and associated methodology. The invention allows the conveyor belt automatically keeps track of and fixes the user's position dynamically with respect to a stationery reference point of the treadmill by adjusting its own speed free hands. Two position measurement techniques and their corresponding belt speed control algorithms are described. Other features of the invention allow users to perceive in real time how their surroundings would be changing by means of video, incline of platform, fan speed, sound and illumination as if they were in fact running in the natural environment. Real time positions of the runner and his partners on other treadmills with respect to a chosen track are displayed. The invention also utilizes a vectored controlled 2 / 3-phase AC induction motor or a BLDC motor to drive the conveyor belt for energy efficiency and fast response.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 966,247 filed Feb. 20, 2014, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a device for walking or running while staying in the same place, commonly referred to a treadmill, enhancements and adaptations to existing treadmills, and associated methodology. Specifically, the treadmill aspect of the invention involves a modification to conventional drives found in domestic applications, a position sensing device, a speed controlling algorithm to dynamically fix the user or runner at the same position and a virtual environment to aid walking and running with Internet based social communication. In this document, the terms “user” and “runner” share the same meaning, i.e. the human body moving on the moving belt of the treadmill.BACKGROUND OF THE INVENTION[0003]Treadmills are popular exercise machines for running or...
