With example samjhte hai.... Me ek aise pendent ki baat kr rahi hu jise girls as jewellery use kr saqti hai.... Jo upar se to stone dikhega lekin usme .. notification chip jo hamari location nearest police station or apne parijano ko dega ... Halaki

Plus point. Iski madad se chaar diwaari k andar hone aise masle bhi hal ho saqte.... Kyu k shor pehchan he help ki hogi ... Low point converter:- iske shor se ye problem hogi k petient ya buzurgo ko takleef ho saqti hai... To iske liye iske hum sast

Idea is good but is it practically implementable 1. Which speaker are you gonna use as I have never heard of any pendant size speakers covering a range of 2 to 3 km 2. How will the device trigger the siren, does the wearer will have to do it manua

Hum iska last size 2 inch kr saqte hai..... Baki I Surrender... Need solution....
