A portion of the disclosure of this patent document contains material that is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or patent disclosure as it appears in the Patent and Trademark Office, patent file or records, but otherwise reserves all copyright rights whatsoever.
One or more embodiments of the invention generally relate to locating objects. More particularly, one or more embodiments of the invention relate to locating objects based on a signal strength between a master and slave transreceiver.
The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
The following is an example of a specific aspect in the prior art that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. By way of educational background, another aspect of the prior art generally useful to be aware of is that real-time locating systems are used to automatically identify and track the location of objects or people in real time, usually within a building or other contained area. Wireless real-time locating systems tags are attached to objects or worn by people, and in most real-time locating systems, fixed reference points receive wireless signals from tags to determine their location.
Typically, the physical layer of real-time locating systems technology is usually some form of radio frequency communication, but some systems use optical or acoustic technology instead of or in addition to radio frequencies. Tags and fixed reference points can be transmitters, receivers, or both, resulting in numerous possible technology combinations.
Typically, radio frequency is a rate of oscillation in the range of about 3 kHz to 500 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.
In view of the foregoing, it is clear that these traditional techniques are not perfect and leave room for more optimal approaches.
The present invention is illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which like reference numerals refer to similar elements and in which:
Unless otherwise indicated illustrations in the figures are not necessarily drawn to scale.
Embodiments of the present invention are best understood by reference to the detailed figures and description set forth herein.
Embodiments of the invention are discussed below with reference to the Figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. For example, it should be appreciated that those skilled in the art will, in light of the teachings of the present invention, recognize a multiplicity of alternate and suitable approaches, depending upon the needs of the particular application, to implement the functionality of any given detail described herein, beyond the particular implementation choices in the following embodiments described and shown. That is, there are numerous modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive.
It is to be further understood that the present invention is not limited to the particular methodology, compounds, materials, manufacturing techniques, uses, and applications, described herein, as these may vary. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to “an element” is a reference to one or more elements and includes equivalents thereof known to those skilled in the art. Similarly, for another example, a reference to “a step” or “a means” is a reference to one or more steps or means and may include sub-steps and subservient means. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than that of a logical “exclusive or” unless the context clearly necessitates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise.
Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferred methods, techniques, devices, and materials are described, although any methods, techniques, devices, or materials similar or equivalent to those described herein may be used in the practice or testing of the present invention. Structures described herein are to be understood also to refer to functional equivalents of such structures. The present invention will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings.
From reading the present disclosure, other variations and modifications will be apparent to persons skilled in the art. Such variations and modifications may involve equivalent and other features which are already known in the art, and which may be used instead of or in addition to features already described herein.
Although Claims have been formulated in this application to particular combinations of features, it should be understood that the scope of the disclosure of the present invention also includes any novel feature or any novel combination of features disclosed herein either explicitly or implicitly or any generalization thereof, whether or not it relates to the same invention as presently claimed in any Claim and whether or not it mitigates any or all of the same technical problems as does the present invention.
Features which are described in the context of separate embodiments may also be provided in combination in a single embodiment. Conversely, various features which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination. The Applicants hereby give notice that new Claims may be formulated to such features and/or combinations of such features during the prosecution of the present application or of any further application derived therefrom.
References to “one embodiment,” “an embodiment,” “example embodiment,” “various embodiments,” etc., may indicate that the embodiment(s) of the invention so described may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one embodiment,” or “in an exemplary embodiment,” do not necessarily refer to the same embodiment, although they may.
As is well known to those skilled in the art many careful considerations and compromises typically must be made when designing for the optimal manufacture of a commercial implementation any system, and in particular, the embodiments of the present invention. A commercial implementation in accordance with the spirit and teachings of the present invention may configured according to the needs of the particular application, whereby any aspect(s), feature(s), function(s), result(s), component(s), approach(es), or step(s) of the teachings related to any described embodiment of the present invention may be suitably omitted, included, adapted, mixed and matched, or improved and/or optimized by those skilled in the art, using their average skills and known techniques, to achieve the desired implementation that addresses the needs of the particular application.

The present invention will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings.
There are various types of tracking systems that may be provided by preferred embodiments of the present invention. In one embodiment of the present invention, the tracking system may provide a plurality of transreceivers that simultaneously emit an alert signal when a distance, trajectory, or velocity of a transreceiver causes a signal level to fall below a predetermined threshold. In some embodiments, a master transreceiver may send out a signal having a constant strength to a plurality of slave transreceivers or a single transreceiver. In some embodiments, the master transreceiver may send several types of signals on different frequencies through different channels to several different slave devices on different time and each slave device is contacted sequentially. Those skilled in the art, in light of the present teachings, will recognize that the strength of the signal between the master and slave transreceivers may include a magnitude of an electrical field at the slave transreceiver in relation to the master transreceiver. In some embodiments, changes in the distance between the master and slave transreceivers may indicate a change in trajectory and velocity between the transreceivers. A received signal strength indicator (RSSI) may detect and indicate the changes in distance between the transreceivers. For example, without limitation, the constant signal received by the slave transreceivers may weaken as the distance between transreceivers increases. The received signal strength indicator may identify the change from a constant signal to a weaker or stronger signal. A processor may include the means to detect the changes in signal strength. For example, without limitation, when the tracking system detects that the constant signal between transreceivers is weaker, the master transreceiver and the slave transreceivers may start to communicate on a much more frequent basis to verify the reduced signal strength and mitigate false alarms. In this manner, if the signal continues to transmit at a weaker strength, the transreceivers may be moving apart from each other. In some embodiments, the slave transreceiver may position on the object, whereby the master transreceiver may detect a relative distance to the object by transmitting the signal to the slave transreceiver The user may locate the devices through audio tones generated by the devices. In some alternate embodiments, the transreceivers further include Global Positioning Satellite (GPS) receivers. With the use of GPS, the locations of each transceiver can be known, within the resolution of the GPS. In yet another embodiment, the master transreceiver may utilize triangulation to determine the position, velocity, and trajectory of the slave transreceivers, and thereby the object. Those skilled in the art, in light of the present teachings, will recognize that the master transreceiver may determine the location of the slave transreceivers by measuring angles from known points at either end of a baseline.
In one embodiment of the present invention, the tracking system may include an alert signal to indicate changes in the signal strength between the transreceivers. The alert signal may trigger when the constant signal strength between the master and slave transreceivers falls below a predetermined strength or threshold. The signal may include, without limitation, a radio frequency, radiation, illumination, laser, and a sound wave. In some embodiments, the signal may be encrypted to restrict duplication. In some embodiments, the alert signal may continuosly provide an audible signal until the master transreceiver and the slave transreceiver are in possession of the user. However, in other embodiments, the alert signal may terminate after a predetermined time interval. In some embodiments, a volume control portion may regulate the volume of the alert signal. However in another embodiment, the alert signal volume may be adjusted only if the master transreceiver and the slave tranreceivers are set to the same setting. In one embodiment, if one transreceiver is turned to a lower volume and the other transreceiver remains on the higher setting, then the alert signal may default to the higher audible setting. In yet another embodiment, only a user who physically possesses both transreceivers may adjust the volume control to a lower alert signal.
In one embodiment of the present invention, the transreceivers may include a master transreceiver, and a slave transreceiver. Each respective transreceiver may communicate in master/slave mode where the master transreceiver initiates a data frame with to the slave transreceiver. The contents of the data frame may include a short encrypted message used to bond the master and slave. The master transreceiver may detect the signal strength from the slave transreceivers to determine whether to generate an alert signal. In one embodiment, a user may have access to the master transreceiver, while an object to be tracked may be fitted with a slave transreceiver. In this manner, the tracking system may dynamically alert the user that the object exceeded a predetermined range. In some embodiments, the network may include a single master transreceiver and a plurality of slave transreceivers. The network may be configured to tie the master transreceivers and the slave transreceiver together for communication. In this manner, any element of the tracking system may help locate an object tagged with a slave transreceiver by first alerting the master transreceiver, and then forwarding the alert to the slave transreceiver on the object.
In one embodiment of the present invention, the tracking system may include a mobile encrypted network. The network may encrypt the signals when transmitting them between each transreceiver. In this manner, the network may be operable to inhibit interference from other networks or systems designed to hinder signals. Those skilled in the art, in light of the present teachings, will recognize that the encryption of signals may be efficacious in protecting military or commercial interests in the location of the object. Encryption of the signal may include, without limitation, encryption algorithm such as, but not limited to, an advanced encryption standard (AES) that converts the signal into an unreadable ciphertext.
In one embodiment of the present invention, the tracking system may include a charger system. The charger may have an embedded program port which automatically updates and synchronizes the master and slaves' firmware while allowing the user to adjust certain security-related parameters. During the charging process, transceivers continue to send the signals to each other. However, while connected to the charger, the user may opt for the transceivers to be reprogrammed and updated, which would lead the transceivers to use the program port exclusively to communicate with each other through the charger. In some embodiments, the charger may set a predetermined threshold distance for the signal. When the signal exceeds the threshold, the transreceivers may emit an alert signal. In some embodiments, the slave transreceiver may detect the signal strength of the master transreceiver, while the master transreceiver may detect the signal strength of the rest of the slave transreceivers. In some embodiments, if the master transreceiver is lost, the tracking system may be reset so that the charger selects a new master transreceiver from the remaining slave transreceivers. The remaining transreceivers may then be synchronized to transmit and receive signals as appropriate. In some alternate embodiments, the charger may be in communication with local or mobile computing device. The communication may be established by either a wired or wireless connection. The user of the computing device may then view and set operating parameters for the tracking system.
In one embodiment of the present invention, the transreceivers may include a master transreceiver 106, and a plurality of slave transreceivers 108. In some embodiments, the transreceivers may communicate in master/slave mode where a master transreceiver initiates the data frame with a slave transreceiver. The master transreceiver may detect the signal strength from the slave transreceivers to determine whether to generate an alert signal. In one embodiment, a user may have access to the master transreceiver, while an object 102 to be tracked may be fitted with a slave transreceiver. The relative distance to the object may then be identified based on the signal strength between the master and slave transreceiver. In this manner, the tracking system may dynamically alert the user that the object exceeded a predetermined range. For example, without limitation, the master transreceiver may join with a personal key chain, while a slave transreceiver joins with a wallet. The distance to the wallet may be monitored by a user as long as the key chain remains with the user. When the wallet exceeds a predetermined threshold from the key chain, the alert signal may trigger on both the key chain and the wallet. The present embodiment enables a master transceiver to accept up to three slaves while being capable of accepting up to ten downstream slaves while acting itself as a slave to another master, allowing for effectively unlimited connections using cascading techniques. The number of slaves is limited by the power of the microprocessor. In a non-limiting example, using a 64 bit processor and without power limitations, thousands of slaves may be connected to one master.
In one alternative embodiment of the present invention, destruction or failure of any one of the transreceivers may result in triggering alert signals on the remaining transreceivers. In yet another embodiment, unauthorized movement of any of the transreceivers may trigger alert signals on the remaining transreceivers. In yet another embodiment, attempts to jam the signal between the transreceivers may trigger alert signals on the remaining transreceivers. In one alternative embodiment, the signals from the master and slave transreceiver may travel to a remote satellite and server for redirection and analysis at a remote control center. In this manner, the relative distance to the object may be monitored from the remote control center. In yet another alternative embodiment, a social site may be utilized to monitor the object, whereby the transreceivers transmit a signal to a server.
In one embodiment of the present invention, the tracking system may include an alert signal to indicate changes in the signal strength between the transreceivers. The alert signal may trigger when the constant signal strength between the master and slave transreceivers falls below a predetermined strength or threshold. The signal may include, without limitation, a radio frequency, radiation, illumination, laser, and a sound wave. In some embodiments, the signal may be encrypted to restrict duplication. In some embodiments, the alert signal may continuously provide an audible signal until the master transreceiver and the slave transreceiver are in possession of the user. However, in other embodiments, the alert signal may terminate after a predetermined time interval. In some embodiments, a volume control portion may regulate the volume of the alert signal. However in another embodiment, the alert signal volume may be adjusted only if the master transreceiver and the slave tranreceivers are set to the same setting. In one embodiment, if one transreceiver is turned to a lower volume and the other transreceiver remains on the higher setting, then the alert signal may default to the higher audible setting. In yet another embodiment, only a user who physically possesses both transreceivers may adjust the volume control to a lower alert signal.
In one embodiment of the present invention, the tracking system may include a mobile encrypted network. The network may encrypt the signals when transmitting them between each transreceiver. In this manner, the network may be operable to inhibit interference from other networks or systems designed to hinder signals. Those skilled in the art, in light of the present teachings, will recognize that the encryption of signals may be efficacious in protecting military or commercial interests in the location of the object. Encryption of the signal may include, without limitation, an encryption algorithm that converts the signal into an unreadable ciphertext. In some embodiments, the mobile encrypted network may include a single master transreceiver and a plurality of slave transreceivers. The mobile encrypted network may be configured to tie the master transreceivers and the slave transreceiver together for communication. In this manner, any element of the tracking system may help locate an object tagged with a slave transreceiver by first alerting the master transreceiver, and then forwarding the alert to the slave transreceiver on the object. In one embodiment, the network may include encrypted communication between each transreceiver. In this manner, the network may be operable to inhibit interference from other networks or systems designed to hinder signals. The network may include various communication protocols for allowing the transreceivers to communicate with each other, including, without limitation, two Ethernets, hardware and link layer standard, Internet protocol suite, host-to-host data transfer, and application-specific data transmission formats.
