Single-Coil Key Programmer Using Switchable IR, ASK, and FSK

The patent applies universality by enabling a single activation coil to perform multiple functions through software-controlled modulation. The coil can generate different resonant voltages (infrared modulation, amplitude shift keying, frequency shift keying) to activate various key types, replacing the need for multiple dedicated coils while maintaining full compatibility with different key frequencies and protocols

The patent implements dynamics by making the activation coil's characteristics changeable through software control. The coil's resonant frequency and voltage output are dynamically adjustable via modulation circuits, allowing it to adapt to different key types in real-time rather than being fixed to a single frequency or function

The patent reduces production costs by replacing multiple physical coils with a single universal coil配合modulation circuits. This eliminates the need to manufacture, stock, and assemble multiple coil components, reducing material costs, assembly complexity, and inventory requirements while maintaining the ability to service all key types

The patent substitutes the mechanical approach of using multiple physical coils with an electronic/software-based solution. Instead of mechanically selecting different coils for different key types, the system uses electronic modulation circuits and software control to dynamically adjust the single coil's output, simplifying the hardware architecture and reducing manufacturing complexity
