Abstract

Systems and methods include a medical device that matches an identifier received over its optical channel and associated with a control device within a line-of-sight of the medical device with an identifier received over its wireless channel and that automatically pairs with the control device associated with the matching identifier over its wireless channel, as well as, a control device that matches an identifier received over its optical channel and associated with a medical device within a line-of-sight of the control device with an identifier received over its wireless channel and that automatically pairs with the medical device associated with the matching identifier over its wireless channel, as well as, a first device and a second device that automatically pair over a wireless channel based on a location identifier received over an optical channel from a transmitter within a line-of-sight of the first device and the second device.

Claims16

Dependent claims

An automatically pairable medical device, comprising:

a first communication system configured to communicate via a first communication channel;
a second communication system configured to communicate via a second communication channel;
a processor;
and
a memory storing program instructions, the program instructions, when executed by the processor, causing the processor to:
receive a first identifier associated with a first control device within a line-of-sight of the medical device over the first communication channel;
receive at least one identifier associated with at least one control device over the second communication channel;
determine that the first identifier received over the first communication channel matches an identifier of the at least one identifier received over the second communication channel;
automatically pair with the first control device associated with the matching identifier over the second communication channel;
receive a second identifier associated with a second control device within the line-of-sight of the medical device over the first communication channel;
automatically disassociate from the first control device if the first identifier is not detected over the first communication channel;
determine that the second identifier received over the first communication channel matches an identifier of the at least one identifier received over the second communication channel;
and
automatically pair with the second control device associated with the matching second identifier over the second communication channel.

A system for automatically pairing devices, the system comprising:

a transmitter positioned within a location, the transmitter configured to transmit a location identifier over a first communication channel to devices with a line-of-sight of the transmitter;
a first device configured to:
receive the location identifier over the first communication channel;
and
transmit the location identifier and an identifier associated with the first device over a second communication channel;
a second device configured to:
receive the location identifier over the first communication channel;
and
transmit the location identifier and an identifier associated with the second device over the second communication channel;
wherein the first device is further configured to:
scan the second communication channel for the location identifier received over the first communication channel;
determine that the location identifier received over the first communication channel matches a location identifier on the second communication channel;
determine the second device identifier associated with the matching location identifier;
and
automatically pair with the second device associated with the second device identifier over the second communication channel;
and
wherein the second device is further configured to:
scan the second communication channel for the location identifier received over the first communication channel;
determine that the location identifier received over the first communication channel matches a location identifier on the second communication channel;
determine the first device identifier associated with the matching location identifier;
and
automatically pair with the first device associated with the first device identifier over the second communication channel.
