Latest Patents

Masao Nakagawa's latest patents demonstrate his commitment to improving emergency response systems. One notable invention is the **Emergency Lamp and Wireless Emergency Lamp Data Transmission System**. This invention utilizes an LED as a light source for emergency lighting. In normal conditions, data is received via a power line and stored in a data memory. When an emergency occurs, a switch transitions the power supply from the line to a battery, activating the LED to emit light. Notably, the stored data is read and modulated to control the LED's blinking and intensity, allowing vital information—such as emergency exit routes—to be transmitted through light communication.

Another significant invention is the **Illuminative Light Communication Device**. This technology addresses challenges in light communication by featuring a system with an LED light source coupled with a power line for electric supply. The device includes a data modulator that transmits multiple pieces of data superimposed on an electric power waveform through the power line. A filter is employed to separate modulated data, allowing control over the LED's light intensity and blinking. This innovative approach enables data transmission via variations in light, enhancing communication during emergencies.
