According to the abstract released by the Intellectual Property India: "GPS and light sensor walker Abstract: The invention proposes an advanced smart mobility walker that incorporates a GPS-based sound recognition module and a purposeful lighting function to improve user safety, accessibility, and device traceability. Instead, the walker may concurrently generate illumination and an audio alam1 since the light is only tumed on when the user or caregiver touches the tracker button. This regulated activation makes it easier for users to tind the walker in busy, dark, or confused situations. Conventional walkers arc hard to locate in dimly lit areas because they soinetimes lack visibility characteristics. Additionally, they don't otler a means to track or identify their location, which presents problems for older people, orthopedic .patients, and neurological patients who could unintentionally move away from the walker or forget where it was placed. Conventional walkers also lack integrated safety alarms, which raises the possibility of falls, misplacement, or delayed help. The integrated GPS-activated sound signal of the smart mobility walker, which delivers position information via a linked smartphone or caregiver platform and generates a clear sound alam1, gets around these limitations. When the tracker is tumed on, the additional lighting increases visibility, providing safer recovery and enhanced surface awareness. This invention greatly improves the dependability, convenience, and general safety of walking aids especially for older adults and rehabilitation patients who need dependable assistance during ambulation by fusing stable mobility support with purposeful lighting, sound-based GPS identification, and contemporary tracking technology."
