Abstract
A method is disclosed for calculating a distance to objects or a nearest object to a wireless enabled device. The method includes the steps of broadcasting a signal by the wireless enabled device to data tags, receiving by the data tags the signal by the wireless enabled device, and obtaining by each of the data tags a signal strength indicator of the wireless enabled device based on the signal from the wireless enabled device. Each of the data tags in a range transmits a signal to the wireless enabled device including the signal strength indicator of the wireless enabled device. Each signal strength indicator of the wireless enabled device is communicated to a positioning and communication system.

21. A method for calculating an estimated distance to recently moved or newly tagged objects as a wireless enabled device moves around an environment, the method comprising:
-
receiving by each of the data tags of the recently moved or recently tagged objects a signal including a signal strength indicator of the wireless enabled device based on movements of the wireless enabled device around the environment and in accordance with how long the wireless enabled device stood in front of a certain object or at least one reference point or an access point in the environment; transmitting by each of the data tags associated with the moved or recently tagged objects a signal to the wireless enabled device including the signal strength indicator of the wireless enabled device; communicating each signal strength indicator of the wireless enabled device to a positioning and communication system; calculating the estimating distance responsive to each signal strength indicator by the positioning and communication system; and communicating by the positioning and communication system to the wireless enabled device a list of items, objects, or locations including whether the recently moved or newly tagged objects are to a left, right, in front, back, above or below the wireless enabled device. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. A system for measuring relative signal strength of an wireless enabled device as moving around an environment of recently moved or newly tagged objects, the system comprising:
-
data tags of the recently moved or newly tagged obtain a signal strength indicator from a signal transmitted from each of at least one wireless enabled device responsive to movements of the wireless enabled device around the environment and in accordance with how long the wireless enabled device stood in front of a certain object or at least one reference point or an access point in the environment; and
in response, each of the data tags of the recently moved or newly tagged objects transmit a signal to the wireless enabled device including the signal strength indicator of each of the at least one wireless enabled device; anda positioning and communication system configured to communicate with each of the data tags of the recently moved or newly tagged objects and receive at least one signal strength indicator of each of the at least one wireless enabled device and communicate with each of the at least one wireless enabled device a list of items, objects, or locations including whether the recently moved or newly tagged objects are to a left, right, in front, back, or above or below, wherein the list of items, objects, or locations being responsive to an estimated distance calculated based on the relative signal strength of the wireless enabled device movements around the environment. - View Dependent Claims (31, 32, 33, 34, 35, 36)
