Abstract
A system for connecting disparate communication interfaces. The system includes a dongle and an adaptor. The dongle has a first interface type of connector for connection to a first interface type of port. The adaptor provides a connection to a second interface type of port, and also includes a third interface type of port. A switch in the dongle allows connecting to the third interface type of interface port when connected to the adaptor, and connection to the first interface type of interface port when not connected to the adaptor.
Claims20
A system for connecting disparate communication interfaces, comprising:
- a dongle including:
- a dongle connector for connecting to a port of a first interface type,
- a controller,
- an input connected to the dongle for providing a signal to the dongle indicating the connection of a third interface type,
- a conductor for connecting to the third interface type without interfering with the dongle connector connecting with the port of the first interface type,
- a memory with a non-transitory, computer readable media with instructions for combining signals of the first and third interface types;
- and
- an adaptor including:
- a first adaptor port of the first interface type,
- an adaptor connector for connecting to a port of a second interface type,
- an electrical connection between the first adaptor port and the adaptor connector, and
- a second adaptor port for receiving a connector of the third interface type, and circuitry for connecting the second adaptor port to the dongle.
A system for connecting disparate communication interfaces, comprising:
- a dongle including:
- a dongle connector for connecting to a USB-C port,
- a controller,
- an input connected to the dongle for providing a signal to the dongle indicating the connection of an analog interface,
- an analog to digital converter for converting an analog signal of the analog interface into a digital signal,
- a conductor for connecting to the analog interface without interfering with the dongle connector connecting with the USB-C port,
- a switch for switching at least one conductor of the dongle connector to an analog to digital converter input of the controller,
- a recessed contact, positioned separate from the dongle connector, connected to a control input of the switch,
- a memory with a non-transitory, computer readable media with instructions for combining signals of the USB-C port and the analog interface;
- and
- an adaptor including:
- a first adaptor port of a USB-C interface,
- an adaptor connector for connecting to a USB-A port,
- an electrical connection between the first adaptor port and the adaptor connector, and
- an analog adaptor port for receiving an analog connector, and circuitry for connecting the analog adaptor port to the dongle, and
- a protruding member positioned to engage the recessed contact of the dongle.
A method for connecting disparate communication interfaces, comprising:
- connecting a first adaptor connector of an adaptor to a host port of a second interface type;
- connecting a dongle connector of a dongle to a first adaptor port of a first interface type;
- connecting a connector of a third interface type at a second adaptor port;
- providing a connection signal from the adaptor to a dongle connection input indicating the connection of the connector of the third interface type;
- providing the connection signal from the dongle connection input to a dongle controller;
- connecting at least one signal line from the second adaptor port to the dongle without interfering with the dongle connector connecting with the first adaptor port of the first interface type;
- activating a signal connection to the dongle from the second adaptor port;
- receiving data signals at the dongle from the first and second adaptor ports;
- and
- combining, by the dongle controller, the data signals from the first and second adaptor ports.
