METHOD AND APPARATUS USING RADIO FREQUENCY SIGNAL FOR MEASURING DIRECTION OF HEAD FACE AND HEAD SPEAD OF GOLF CLUB, EXPECTED SHOT DISTANCE, AND EXPENDED CALORIES

摘要

The invention RF (Radio Frequency) data in accordance with a result detected reception sensitivity and the signal strength using the transmission signal a superheterodyne (Super Heterodyne) scheme to output by the microcomputer processor, the received RF frequency Hall Effect antenna ( antenna having a directivity: process the signal of a certain frequency received below referred to as receiving antennas) yield a variety of data, and measure the golf club head face direction, the head speed, and estimated distance of the golf ball flies a need for a golf swing practice and and also output to the screen display by calculating the calories consumed being consumed during the swing, and outputs the four basic data needed when you first enrolled or practice your golf on-screen display to allow effective use of the golf swing practice. ; The golf club head face direction, head speed, estimated distance, calories, golf driving range, impact area, radio frequency, signal generator, an antenna sensor, SMPS power.
