At the age of eleven, Richard Turere lived in Kenya and faced a distressing morning when he discovered that a lion had killed one of his family's cows. This was not an isolated incident; many neighbors were suffering similar losses due to lion attacks. While some individuals wanted to kill the lions to safeguard their livestock, this posed another issue since lions are a key tourist attraction in Kenya and are legally protected. Additionally, their populations are dwindling. To protect their cows, Richard's family took turns watching over them at night. Unfortunately, when everyone fell asleep, the lions managed to breach the fence. Richard initially attempted to deter the lions by placing torches along the fence, knowing that they are afraid of fire. However, he soon realized that the lions were clever enough to exploit the absence of people and continued to attack the cows. He then tried using scarecrows, but these proved ineffective as well. Richard understood that he needed to devise a more effective solution to prevent further losses of his family's cattle.

Richard noticed the behavior of lions near his farm. One night, armed with a torch, he ventured around the stable and felt the presence of lions lurking in the darkness. He realized that as long as they believed a person was nearby to guard the cattle, they would stay away. This sparked an idea in him—a moving light! To the lions, a shifting torch would indicate human presence, deterring them from approaching. He pondered how to create the illusion of a torch in motion. After much experimentation, Richard developed a system using flashing LED lights powered by an old car battery, recharged by a solar panel. He positioned the lights along the fence, so at night, the lights were visible from outside the stable, flashing in sequence to mimic the movement of people with torches. As a result, lions ceased to cross Richard's fence. He named his invention Lion Lights. This effective and non-harmful device established a harmonious coexistence between humans, livestock, and lions. Furthermore, Lion Lights can also deter other wildlife. Richard's innovation has gained popularity and is now utilized throughout Kenya.

As a child, Kenneth Shinozuka experienced a troubling incident when a police officer brought his grandfather home after finding him wandering alone on the street. His grandfather did not recall how he ended up there. It was later discovered that he suffered from Alzheimer's disease, which gradually erases memory and cognitive abilities. While in middle school, Kenneth frequently took care of his grandfather. Whenever his grandfather began to wander, Kenneth would follow him to keep him safe from potential harm. Kenneth often contemplated whether he could provide more assistance. Although his grandfather was secure in his room, the challenge remained that there was no way to predict where he might go once he left the safety of that space.

This situation required someone to be with him constantly. One evening, a glimmer of hope emerged in Kenneth's mind. As he observed his grandfather getting up and stepping onto the floor as usual, a thought occurred to him. To walk, a person needs to place their feet down first. If a patient's movements create loud sounds, similar to walking in clogs, it will alert the caregiver, but also disturb others nearby who are asleep. "No, that won't work," Kenneth mused. But could there be a way to send a specific signal to wake just one person? There must be sensors designed for this purpose. Kenneth's thoughts began to race as he considered the possibilities.

Kenneth developed a system of socks embedded with sensors in the heels, using a smartphone as a monitoring device. The challenge was to make the sensors thin enough to ensure comfort while walking. After experimenting with various materials, he ultimately chose a film sensor powered by a small battery. He then learned programming to create an app that would enable the smartphone to function as a monitor. The resulting system worked effectively; when his grandfather began to walk, the sensors transmitted signals to the connected smartphone, triggering an alarm. The smartphone then displayed his grandfather's movements. Kenneth's innovative sensor socks received recognition at a science fair, and he intended to enhance the device for distribution to Alzheimer's patients as necessary. Both Kenneth and Richard drew inspiration from their observations to bring creative ideas to life. Richard's meticulous study of lion behavior ultimately fostered peace in his village, while Kenneth's insights into his grandfather's wandering led to a helpful device for individuals with Alzheimer's. By observing your environment with a fresh perspective, you might discover something remarkable. Embrace this approach—who knows what extraordinary outcomes may arise?
