发明名称 Geofencing and route adherence in global positioning system with signals from fewer than three satellites
摘要 Particular implementations are particularly useful in providing a system in which the hardware is more easily upgradable and new hardware functionality may be added without adding any new physical hardware. Through placement of an FPGA closely associated with the CPU of a personal computer, the FPGA may be reconfigured to act as new hardware. A system for installing new virtual hardware involves loading firmware into memory associated with the FPGA and reconfiguring the FPGA through a microcontroller. Particular implementations include universal ports associated with the FPGA into which adapter plugs can be placed to quickly adapt to any device that may be added through the virtual hardware use of the FPGA. Other implementations include high density connectors into which a plurality of ports of varying configurations may be plugged for connection of external electronic equipment through the FPGA.
