Physiological origin: Sequential electrical activation of cardiac cells
–Electrical excitation propagates

–End point: ventricular muscles
•Responsible for triggering
cardiac contraction
–Activation does not rely on brain signals Heart can operate on its own

OUR AIM TO BECOME AN EFFICIENT TECHNICAL PHILANTHROPIST PASSIONATE ABOUT RESEARCH & INNOVATION
FEW PREVIOUS INNOVATIONS
CLINICAL DIAGNOSTIC ELECTRONIC STETHO- FETAL DOPPLER WITH GRAPHICAL REPRESENTATION PHONOCARDIOGRAPHY SEMIAUTOMATIC DIGITAL BP APPARATUS (As accurate as conventional sphygmomanometer) Mercury Type 5. 12 LEAD ECG MONITORING . TO BE INTERFACED WITH ANY PC/LAPTOP. AND ( ANDROID CELL PHONE) Can Also be used 24Hr holter App (For bed ridden Pts.) 5 IN 1
2nd INNOVATION DURING COVID CRISES LOW COST PORTABLE VENTILLATOR. LESS THAN INR RS- 3500/
INTRODUCTION Contact Angle Goniometry – Tensiometry θ 13-11-2020 23:34:51 GAS PHASE WHAT IS
INTRODUCTION Cont… Goniometer. It is an instrument used for measuring different Contact angles . Geometrically defined as the angle formed by a liquid at the three phase boundary where a liquid, gas, and solid intersect. GAS PHASE
THE ANGLE IS DEPENDENT ON THE INTERFACIAL TENSIONS BETWEEN GAS AND SOLID LIQUID AND SOLID GAS AND LIQUID. GAS PHASE INTRODUCTION Cont…
PROPOSED DEVICE THE DEVICE IS BASED ON OPTICAL TENSIOMETRY IN WHICH THE LIQUID’S DROP SHAPE IS ANALYSED BY USING A HIGH RESOLUTION HD WIRELESS DIGITAL TECHNOLOGY.
THE SIGNAL IS SENT THROUGH WiFi LINK TO ANDROID , WINDOWS AND I,PHONE PLATFORM. USING A SOFTWARE App
GOAL OF THE PROJECT MAJOR GOAL OF THE PROJECT IS TO DEVELOP A LOW COST GONIOMETER WITHOUT COMPROMISING THE QUALITY. THE AIM IS ALSO TO DEVELOP A 3D ANGLE GONIOMETER THAT WOULD BE AFFORDABLE FOR SCHOOLS, COLLEGES, UNIVERSITIES, RESEARCH INSTITUTIONS, ETC. THE DEVICE TO BE DEVOLOPED WOULD HAVE THE FOLLOWIG FEATURES.
NEW FEATURES OF THE PROJECT CLEAR AND HIGH 3D IMAGE SURFACE TEMPRATURE & HUMIDITY OF A LIQUID DROP. VERY PORTABLE TO CARRY ANY WHERE WITH EASE. SOLAR CHARGING. AC/ DC RECHRGEABLE
NEW FEATURES OF THE PROJECT Cont…….. INTELLIGENT BRILLIANCE CONTROL. RECORDING MODE AND PICTURE MODE FOR STORAGE PURPOSE
