Patent ID: 8391719

Claim:
A method of achieving communications between first and second mobile devices that are in proximity with one another, the method comprising: (a) transmitting a first signal from the first mobile device; (b) receiving a first reflected signal at the first mobile device, the first reflected signal being the first signal reflected by an object in proximity to the first mobile device; (c) based upon receipt of the first reflected signal, transmitting a second signal from the first mobile device for receipt by the second mobile device upon being reflected by the object; (d) receiving a confirmation signal from the second mobile device in response to the second signal; (e) achieving a paired relationship of the first mobile device relative to the second mobile device, whereby because of the paired relationship the first and second mobile devices are capable of additional communications therebetween, and (f) transmitting a third signal from the first mobile device for receipt by the second mobile device upon being reflected by the object, wherein the third signal is representative of data that is to be communicated from the first mobile device to the second mobile device, wherein reflections of the first and second signals associated with (b) and (c) occur off of the object as the object is passing by the first and second mobile devices a first time, wherein a reflection of the third signal associated with (f) occurs off of the object as the object is passing by the first and second mobile devices a second time, and wherein each of the first, second, and third transmitted signals is an infrared signal.
