Two Phase Traffic Diversion System

Technical Description This invention discloses a traffic diversion signaling system that converts a conventional four phase intersection into a simplified two phase scheme using straight through, stop, and custom “C / inverse C” signals. By prohibiting direct right (or left)…

Resonance Driven Behaviour Interface

Technical Description The invention discloses a resonance based human–machine interface that uses body generated vibrational signals to infer, display, and correct human behavioural states in real time. It leverages wearable sensing, centre of mass computation, and controlled feedback signals to…

Portable Limb Rehab Robot

Technical Description This invention is a portable, actuator-driven rehabilitation robot that provides calibrated therapy to human limbs for vertical flexion–extension and horizontal abduction–adduction movements. It forms a closed kinematic chain with the patient’s limb, enabling adaptable, monitored therapy for both…

Linear Inductive Level Sensor

Technical Description This invention is a non-intrusive inductive sensor uses a floating coil inside sealed containers and external planar readout coils to measure liquid levels via mutual inductance ratios. It provides high-resolution (0.73mm) detection for toxic or airtight liquids through…

Moisture-Insensitive Fly Ash Monitor

Technical Description This invention is an online optical instrument that continuously measures fly ash concentration in industrial stacks, even in the presence of high moisture or droplets. It uses a polarized green laser and multi-angle scattering detection to separate fly…

Aqueous Metal-Air Batteries

Technical Description This invention describes a closed-loop system decouples charging/discharging for zinc-air batteries, enabling simultaneous operations via mechanical anode swaps. Parallel electrolyte flow ensures uniform distribution and high energy density for grid-scale storage. Problems Addressed Lacks Simultaneous Recharge Inefficient Intermittent…

Mass Spectrometer Control Interface

Technical Description This invention describes a multi-mode data acquisition and control system for 22-pole RF ion trap coupled with quadrupole mass spectrometers (Q1/Q2), enabling precise ion trapping, scanning, and analysis for gas-phase a stereochemistry studies. FPGA-driven synchronization supports Q1/Q2 scans…

Ubiquitous RF Indoor Mapping

Technical Description This invention is a lightweight Radio Tomographic Imaging (RTI)–based system that generates real-time indoor attenuation maps using mobile RF transceivers with minimal to zero pre deployed infrastructure. It optimizes map resolution, is robust to noisy Wi Fi/UWB localization,…

OFDMA Pilot Data Multiplexing

Technical Description This invention describes an enhanced pilot and data allocation scheme for SC-FDMA (DFT-spread OFDM) that supports robust channel estimation even with single-slot allocation in high-Doppler (high-speed) channels. It preserves the low PAPR advantage of SC-FDMA while introducing flexible…

Lift-Separation KE Sabot

Technical Description This invention describes a lift-separation sabot for kinetic energy projectiles that behaves effectively weightless, thereby minimizing sabot–projectile interference during discard. It increases muzzle velocity and discard performance without raising gun chamber pressure, enabling higher-impact APFSDS rounds for main…
