Position changeable sensor

Abstract

The present disclosure discloses a position changeable sensor which includes a main body and an attaching member. The position changeable sensor is disposed on an exercise equipment, and the main body is disposed in a selectable position on the exercise equipment. The main body includes at least one gravity sensor. The attaching member is disposed on the main body, and the attaching member is removably attached to the exercise equipment and the main body.

What is claimed is: 
     
         1 . A position changeable sensor disposed on an exercise equipment, the exercise equipment comprising two exercise parts having two different motion routes, the position changeable sensor comprising:
 a main body removably disposed on one of the exercise parts, wherein the main body comprises at least one gravity sensor; and   an attaching member disposed on the main body, and the attaching member being removably attached to the exercise equipment and the main body.   
     
     
         2 . The position changeable sensor of  claim 1 , wherein the gravity sensor comprises three to nine sensing axes. 
     
     
         3 . The position changeable sensor of  claim 1 , wherein the attaching member is a magnet, and the exercise part is a metal surface with magnetic induction. 
     
     
         4 . The position changeable sensor of  claim 1 , wherein the attaching member is a chuck, and the exercise part is a flat surface. 
     
     
         5 . A position changeable sensor disposed on an exercise equipment, the exercise equipment comprising two exercise parts having two different motion routes, the position changeable sensor comprising:
 a main body removably disposed on one of the exercise parts, wherein the main body comprises at least one gravity sensor; and   a removable connecting device connected with the exercise equipment and the main body.   
     
     
         6 . The position changeable sensor of  claim 5 , wherein the gravity sensor comprises three to nine sensing axes. 
     
     
         7 . The position changeable sensor of  claim 5 , wherein the removable connecting device is a velcro, a container or a buckle. 
     
     
         8 . A position changeable sensor disposed on an exercise equipment, comprising:
 a main body disposed in a selectable position on the exercise equipment, wherein the main body comprises at least one gravity sensor; and   an attaching member disposed on the main body, and the attaching member being removably attached to the exercise equipment and the main body.   
     
     
         9 . The position changeable sensor of  claim 8 , wherein the exercise equipment is a tennis racket, a golf club or a dumbbell. 
     
     
         10 . The position changeable sensor of  claim 8 , wherein the gravity sensor comprises three to nine sensing axes. 
     
     
         11 . The position changeable sensor of  claim 8 , wherein the attaching member is a magnet, and the exercise part is a metal surface with magnetic induction. 
     
     
         12 . The position changeable sensor of  claim 8 , wherein the attaching member is a chuck, and the exercise part is a flat surface. 
     
     
         13 . A position changeable sensor disposed on an exercise equipment, comprising:
 a main body disposed in a selectable position on the exercise equipment, the main body comprising:
 at least one gravity sensor; and 
 a wireless transmitter connected with the gravity sensor, the wireless transmitter transmitting data outwardly; 
   a wireless handheld device for receiving the data transmitted by the wireless transmitter;   an attaching member disposed on the main body, the attaching member being removably attached to the exercise equipment and the main body; and   a removable connecting device connected with the exercise equipment and the main body.   
     
     
         14 . The position changeable sensor of  claim 13 , wherein the exercise equipment is a tennis racket, a golf club or a dumbbell. 
     
     
         15 . The position changeable sensor of  claim 13 , wherein the wireless handheld device is a cell phone or a Tablet PC. 
     
     
         16 . The position changeable sensor of  claim 13 , wherein the gravity sensor comprises three to nine sensing axes. 
     
     
         17 . The position changeable sensor of  claim 13 , wherein the wireless transmitter uses a Bluetooth signal. 
     
     
         18 . The position changeable sensor of  claim 13 , wherein the removable connecting device is a velcro, a container or a buckle.
