A jump height measuring device for measuring vertical jump height of a user includes a detector and a microphone, which are communicatively engaged to a microcontroller. The detector is positionable on a surface so it can detect feet of a user upon the surface and communicate a first signal to the microcontroller upon the feet leaving the surface. The microphone is attached to a landing mat, which is positionable on the surface proximate to the detector. The microphone detects a sound of the feet of the user landing upon the landing mat and communicates a second signal to the microcontroller. The microcontroller is programmed to calculate a height of a jump based upon a difference in time between receipt of the first signal and receipt of the second signal. The device also can be used as a timer and to assess Explosive Leg Power Force and response time.

Jump height measuring device and method of use

This invention is directed to an automatic pipette which directly detects the volume of an inserted syringe, thus eliminating the need for operator specification of this quantity.
