Portable low-frequency low-power physiological status signal emission device capable of emitting a users physiological data to a receiver through a low-frequency low-power emission signal
A portable low-frequency low-power physiological status signal emission device is provided, which is internally configured with a low-frequency low-power emitter. The low-frequency low-power emitter comprises a sensor, a directional antenna and a control module. The control module is utilized to control the sensor to sense a users human physiological status, to process the human physiological status as a human physiological status signal, and to emit the human physiological status signal to a receiver through the directional antenna. A long shaft of the directional antenna has an axis that is kept at a specific angle relative to a traverse line of the users upper limbs. With the setting of the specific angle, the directional antenna can be substantially parallel to a receiving antenna when the users limbs are swinging. Due to the directional antenna and the receiving antenna which are substantially parallel to each other at least in a specific period, the signal transmission process can be effectively performed, and no interference affects other instruments in the signal transmission process.本發明係提供一種可攜式低頻低功率之生理狀態信號發射裝置,其內部設置低頻低功率發射器,包括感測器、指向性天線及控制模組;控制模組控制感測器感測使用者之人體生理狀態,將之處理成人體生理狀態訊號,並透過指向性天線發送至接收器;其中,指向性天線之長軸的軸心線與使用者之上肢的橫切線呈特定角度,該特定角度係設定為當使用者之上肢擺動時,能讓指向性天線大致地平行於接收天線。藉此,由於指向性天線及接收天線能夠至少於一特定期間大致地平行,故可確保訊號被有效地傳輸,在傳輸訊號時也不會對其他儀器造成干擾。13‧‧‧指向性天線3‧‧‧可攜式低頻低功率之生理狀態信號發射裝置rh、lh‧‧‧上肢α‧‧‧軸心線β‧‧‧橫切線θ‧‧‧特定角度
