Appl. No.:

09/592928

Inventors:

Hong Da Tang - Pittsburgh PA
Chanakya C. Damarla - Pittsburgh PA
Mark D. Pollard - Pittsburgh PA

Assignee:

PanGo Networks, Inc. - Pittsburgh PA

International Classification:

H04Q 700

US Classification:

370469, 370328, 34082536, 34082549

Abstract:

In general, the present invention provides in one aspect thereof a device for proximity-based communication between the device and at least a second device. The device preferably includes: a communication unit adapted to communicate between the first device and the second device in a wireless manner; a network layer that includes a communication specification for communicating information between the device and the second device through the communication unit, the network layer being adapted to determine or detect physical proximity between the device and the second device and communicate information regarding detection of physical proximity between the device and the second device or a lack of detection of physical proximity between the device and the second device; a PAN Cell Management layer that receives the physical proximity information from the network layer over time, the PAN Cell Management layer translating the physical proximity detection information received over time into time- and proximity-based events; and an application layer including a memory in which at least one computer application is stored, the PAN Cell Management layer communicating information of occurrence of at least one of the proximity-based events to the computer application so that the computer application can perform a task programmed to be performed on occurrence of the one of the proximity-based events.

International Classification:

H04Q 7/00

US Classification:

4554142, 4554042, 4554963, 370469

Abstract:

A system for delivery of services to at least one client program on a mobile device adapted to communicate in a wireless manner including a plurality of communication/detection devices. Each of the communication/detection devices has a known range and is adapted to detect the presence of the mobile device when the mobile device is within the range thereof. Each communication/detection device is also adapted to communicate information between the mobile device and the communication/detection device when the mobile device is within the range thereof. The system further includes at least one multiplexer in communication with at least one of the communication/detection devices and at least one server including content stored thereon to provide at least one service to the client program on mobile device. The server is in communication with the multiplexer. The service to be provided to the mobile device depends on which one of the plurality of communication/detection devices is in communication with the mobile device.
