Multi-purpose peripheral interface for computing systems
View Patent ↗A system for interfacing a multi-interface card to a non-standard interface is provided. The system includes a detection module that detects an input signal; and a switching module that operationally couples the multi-interface card to an interface based on the input signal. The switching module operationally couples the multi-interface card to a serial interface, a USB interface, a PCMCIA interface or to any non-PCMCIA interface. The system also provides a docking device that is coupled to a computing device, for interfacing a multi-interface card to non-standard interfaces. The docking device includes an interface that receives the multi-interface card; detection logic for detecting the multi-interface card; and a converter that receives signal from the multi-interface card and converts the signals based on an interface that couples the docking device to the computing system.
1. A system for a computing system, comprising:
a docking device that interfaces with the computing system via a cable; and a multi-interface card with a switching module and a processor; wherein the docking device receives the multi-interface card and detects if the multi-interface card is a standard or a non-standard PCMCIA card, and the switching module is coupled to at least a fire wire interface, USB interface, serial interface and a PCMCIA interface; and when the processor detects a standard PCMCIA signal the multi-interface card operates as a standard PCMCIA card and if an input signal is a non-standard PCMCIA signal, then switching module couples the multi-interface card to an interface based on the non-standard PCMCIA signal; wherein the non-standard PCMCIA signal is generated via a pin which is grounded for a standard PCMCIA card; and if a non-multi-interface card is inserted in the docking device, the docking device generates a signal so that the non-multi-interface card is not powered up.
2. The system of claim 1 , wherein the multi-interface card is operationally coupled to any other interface.
3. The system of claim 1 , wherein the multi-interface card may be a modified compact flash card.
4. A docking device for a computing system, comprising:
a modified interface that receives a multi-interface card with a switching module and a processor; wherein the modified interface receives and detects if the multi-interface card is a standard or a non-standard PCMCIA card; wherein the switching module is coupled to at least a fire wire interface, USB interface, serial interface and a PCMCIA interface;
a detection logic for detecting a signal, if a standard PCMCIA signal is detected, the multi-interface card operates as a standard PCMCIA card and if an input signal is detected, the multi-interface card operates as a non-standard PCMCIA signal and the switching module couples the multi-interface card to an interface based on the non-standard PCMCIA signal; wherein the non-standard PCMCIA signal is generated via a pin which is grounded for a standard PCMCIA card; and if a non-multi-interface card is inserted in the docking device, the docking device generates a signal so that the non-multi-interface card is not powered up; and
a converter that receives the signal from the multi-interface card and converts the signal based on the interface that couples the docking device to the computing system.
5. The docking device of claim 4 , wherein the converter is a RS-232 converter which converts signals from the multi-interface card such that the signal can be read by a serial port.
6. The docking device of claim 4 , wherein the multi-interface card may be a modified compact flash card.
