System and process for discovery of network-connected devices
First Claim
1. A system for a discovering electronic device to discover the presence and network address of one or more discoverable electronic devices which are connected to the same network as the discovering device and which are located in the same delimited space as the discovering device, comprising:
- a general purpose computing device residing in the discovering electronic device;
a computer program comprising program modules executable by the general purpose computing device, wherein the computing device is directed by the program modules of the computer program to, receive a signature signal transmitted by a one of said one or more discoverable electronic devices, wherein the signal comprises data representing a signature of the discoverable device indicative of its presence in the delimited space and its being accessible via said network, transmit a request signal for receipt by the discoverable electronic device whose signature was received which requests the address assigned to that discoverable device on the network to be transmitted to the discovering device, and receive a reply signal transmitted by the discoverable electronic device whose signature was received which comprises data representing the requested network address, wherein the signature, request and reply signals are not transmitted via the network and are transmitted in a manner that substantially limits their reception to the delimited space.

Abstract
A system and process for discovery between endpoint component devices and computing devices residing in the same delimited space, such as conference room, in cases where the devices are connected to a common local network, is presented. The present invention allows a device in the space to discover the presence and network address of another device in the space, which then allows the first device to negotiate with the discovered device to facilitate the transfer of data and other communications over the common network. However, this discovery is accomplished without the use of the common network, and is limited to discovering devices residing in the same delimited space also containing the discoverable devices.

15. A computer-implemented process for a discovering electronic device among at least one discoverable electronic devices, each of which is connected to a common network and located in the same delimited space, to discover the presence and network address of one or more of said discoverable electronic devices to facilitate the transfer of data and other communications over the common network, said process comprising using a computer to perform the following process actions:
-
the discovering device receiving a signal transmitted by a discoverable electronic device, wherein the signal comprises data representing the address assigned to the discoverable device on the common network, and wherein the signal is not transmitted via the common network and is transmitted in a manner that substantially limits its reception to the delimited space; and
the discovering device using the received network address to establish communications via the common network with the discoverable device that transmitted the address. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A system for a discovering electronic device to discover the presence and network address of one or more discoverable electronic devices which are connected to the same network as the discovering device and which are located in the same delimited space as the discovering device, comprising:
-
a general purpose computing device residing in the discovering electronic device;
a computer program comprising program modules executable by the general purpose computing device, wherein the computing device is directed by the program modules of the computer program to, transmit a request signal which requests the network address assigned to a discoverable device be transmitted to the discovering device, and receive a reply signal transmitted by a discoverable electronic device which comprises data representing the requested network address, wherein the request and reply signals are not transmitted via the network and are transmitted in a manner that substantially limits their reception to the delimited space. - View Dependent Claims (25, 26, 27, 28, 29)

30. A computer-readable medium having computer-executable instructions for facilitating the discovery of the network address of a discoverable electronic device by a discovering electronic device, wherein each device is connected to a common network and located in the same delimited space, said computer-executable instructions comprising:
-
transmitting a signal comprising data representing the address assigned to the discoverable device on the common network from the discoverable device to the discovering device, wherein the signal is not transmitted via the common network and is transmitted in a manner that substantially limits its reception to the delimited space; and
repeating the transmission of the signal on a prescribed periodic basis.
