DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Illustrative embodiments of the system and method of use of the present application are provided below. It will of course be appreciated that in the development of any actual embodiment, numerous implementation-specific decisions will be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.
The system and method of use in accordance with the present application overcomes one or more of the above-discussed problems commonly associated with conventional asset location and management systems. Specifically, the system and method of use of the present application provide efficient, automated means to locate and manage assets across a large area and with minimal risk of human error. These and other unique features of the system and method of use are discussed below and illustrated in the accompanying drawings.
The system and method of use will be understood, both as to its structure and operation, from the accompanying drawings, taken in conjunction with the accompanying description. Several embodiments of the system are presented herein. It should be understood that various components, parts, and features of the different embodiments may be combined together and/or interchanged with one another, all of which are within the scope of the present application, even though not all variations and particular embodiments are shown in the drawings. It should also be understood that the mixing and matching of features, elements, and/or functions between various embodiments is expressly contemplated herein so that one of ordinary skill in the art would appreciate from this disclosure that the features, elements, and/or functions of one embodiment may be incorporated into another embodiment as appropriate, unless described otherwise.
The preferred embodiment herein described is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is chosen and described to explain the principles of the invention and its application and practical use to enable others skilled in the art to follow its teachings.
Referring now to the drawings wherein like reference characters identify corresponding or similar elements throughout the several views, FIG. 2 depicts a top view of an interactive asset location and management system 201 in accordance with a preferred embodiment of the present application. System 201 comprises an asset 203 paired to a transmitter 205 in wireless communication with a database 207 that is also in wireless communication with a querying device 209 such as a cellphone, it should be understood the querying the device could be any other computing device that is capable of sending and receiving data.
It is contemplated and will be appreciated that transmitter 205 can be made highly cost effective by using a low energy beacon such as Bluetooth that does not rely on geo-positioning or cellular technology and can be paired to asset 203 via transmitted IDs. It will be further appreciated a user 211 can use querying device 209 to search for asset 203 via parameters such as stock number, asset ID, VIN #, or location within a parking lot 213. And that the asset can be paired to the transmitter 205.
Referring now to FIG. 3, a flowchart defining the process of FIG. 2 is shown. As described above system 201 comprises the following steps: individual assets paired to transmitters 303, said transmitters conveying asset information and locations to a database 305, one or more devices querying the database for asset information and locations 307, an interactive distance determination process 309, and the visualization of asset location and information on the querying device 311. Where the transmitters provide a signal that allows the database to retrieve information related to the asset.
One of the unique features believed characteristic of the present application is that system 201 implements an interactive distance determination process and visualization software as demonstrated by steps 309 and 311 of FIG. 3, respectively.
Referring now to FIG. 4 the interactive distance determination process of step 309 is shown. Here, step 309 incorporates a self-improving algorithm that provides asset location information 403 and distance 405 to a querying device (not shown). To increase the precision of asset location information 403 the algorithm also measures the distance of the querying device from other asset locations 407, normalizes all historical location data with real-time updates 409, and removes any anomalous data 411.
An alternative embodiment significantly enhances the interactive distance determination process of step 309 by also incorporating stationary transmitters that identify fixed location information to a querying device. For example, stationary transmitters will allow the self-improving algorithm to determine on which floor an asset is located within a parking garage.
It is contemplated that steps 309 and 311 can be used to show asset 203 in a spreadsheet, on a map, by received signal strength indication (RSSI), or by any other useful form of presentation.
It is also contemplated that transmitter 205 can include sensors such as accelerometers or thermometers (not shown) that inform the database 207 and user 211 of important status changes such as asset 203 relocation or harmful interior temperatures that could result in higher maintenance costs. It will be appreciated that this functionality can be paired with software to automatically assign and track employee tasks. For example, software can associate changes to an asset's location with the querying device nearest the asset at that time to determine who would have moved the asset and to automatically task that individual with returning the asset.
An alternative embodiment for system 201 contemplates integrating steps 309 and 311 with sales data and time stamps to optimize where each asset 203 should be located within parking lot 213 to maximize sales. Another alternative embodiment contemplates integrating steps 309 and 311 with a customer relationship management platform (CRM) that can, for example, interact with the social media content of potential customers to pre-identify each customer's vehicle preferences, assign employee tasks, or alert asset owners to consumer trends. It will be appreciated that these alternative embodiments will enhance the sales experience, particularly if the respective querying devices of the employee and customer recognize proximity to each other and correlate customer preferences with inventory.
Referring now to FIG. 5 an alternative embodiment of the system 201 is depicted. Embodiment 501 includes similar features as system 201 but also includes gateways 503 each with a transmitter 505 attached thereto and in electrical communication therewith. A first asset 507 has a first transmitter tag 515 and a second transmitter tag 517 attached at different physical placed of the asset. For example, the asset is a car, and the first transmitter is attached near the front of the car and the second transmitter is attached near the rear of the car. Embodiment 501 includes a second asset 509 with a first single transmitter tag 519 and third asset 511 with a second single asset tag 521.
The gateways 503 broadcast their signal over a range that could be less than the area of operations 523 such as the parking lot of system 201. The gateways 503 gather data from all of the transmitters within this range. When the first transmitter 515 and second transmitter 517 of the first asset 507 communicate with the gateways 503 the position and facing of the asset are determined either by the gateway 503 or the database 207.
It will be understood that in this embodiment multiple gateways 503 communicate with the same transmitter such as with third asset 511 and its transmitter 521. The data from both gateways 503 is combined by the database so that the location of the third asset 511 is a conglomeration of all the measurements taken by the system. It will be appreciated that multiple communications and the resulting measurements increase the accuracy and precision of the embodiment 501.
It is contemplated that the gateways 503 with their attached transmitter tags 505 communicate with each other to produce a measure of signal strength within the system. Therefore gateways 503 with transmitter tags 505 are strategically placed around the area of operations 523 and their location data taken to create a web thereof to provide a holistic view of the assets therein. Algorithms in the database detect weak areas within the web, combine data from all of the gateways for each asset, and determine the relationship between the assets such as distance. These weak areas could be created by obstacles such as walls, metallic objects, furniture and the like that refract or reflect propagated waves from the transmitters to the gateways. It is however contemplated that within the operating area 523 that there could be a single gateway that captures data from the transmitters in a subset of the operating area where no other gateway reaches. The gateway could preprocess the data obtained prior to communicating the data to the database. The known data from the placement of the gateways provides reference data to improve or facilitate the function of the algorithms within the database.
Additionally, the communication between a transmitter tag 505 and a gateway 503 determines line of sight therebetween. When the communication therebetween is interrupted the gateway 503 determines that there is an obstruction and that an asset could the obstruction. If an asset is the obstruction and the asset has a transmitter tag then the system verifies both the obstruction and the location of the asset.
As the asset moves within the area of operations 523 the change in single strength between the transmitter tag and the gateway will change. This measure of the signal strength could be used the algorithms in the database 207 to provide an accuracy value for the location of each transmitter and thereby each asset. For example, the position of a car could be given as 100 feet from the building within 10 feet, so that the car is from 90 feet to 110 feet from the building.
To further increase the accuracy of the system additional data could be used as is depicted by FIG. 6. Embodiment 601 includes an asset 603 with a first transmitter tag 605 and a second transmitter tag 607 in electronic communication with a gateway 503. The asset 603 also has a tertiary transmitter 609 such as a GPS device in electronic communication with a GPS network 611. The data from the tertiary device 609 is also sent to the gateway 503. It is also contemplated that the system 201 could obtain measurements or other data from the tertiary device 609 through some other means and the present embodiment is given as an example only. By combining the measurements taken by the gateway 503 with that of the tertiary device 609 the position, disposition, or other attributes of the asset are improved.
It is contemplated that the tertiary device 609 also augments and expands the range of the system beyond what the gateways 503 are capable of. For example, when in the parking lot the data from the transmitter tags is sufficient but the addition of the GPS device allows the exit of the car from the lot to be identified, the trip that it takes, and its return to the parking lot are captured thereby. The database via the gateway 503 manages the transition the location tracking of the asset from the tertiary device 609 to the first transmitter tag 605.
For example, the signal and accuracy of the first transmitter tag 605 and tertiary device 609 are monitored by the system and the data from each is used when more accurate than the other, such as when a vehicle enters a building where a GPS signal does not reach the vehicle.
Referring now to FIG. 7, it is contemplated that the database 207 could have a learning module 1103 that utilizes data 1105 from the system to populate a framework 1107 such as a neural network or artificial intelligence. The framework 1107 could include performance standards 1109, functions or algorithms 1111 or other data structures that allow the framework 1107 to alter the performance of the system through an improvement routine 1113. The improvement routine 1113 creates, recommends, or actuates changes in the system with the goal of improving the performance thereof. An evaluation routine 1115 monitors the changes within the system and reports to the framework 1107 the results of the changes. For example, the framework 1107 collects data relative to the area of coverage of the gateways within the system, a weak area of coverage is identified and the improvement routine 1113 suggest the addition of new gateways or boost the strength of existing gateways to cover the weak area. The evaluation routine 1115 monitors the change and reports on the effective coverage of the identified weak area.
In another example, location specific data from the gateways (e.g. latitude and longitude measurements) is received by the framework 1107 where an algorithm uses weights and biases along with a cost function to increase the accuracy of system.
It is further contemplated that historical data collected from the system of similar embodiments could be accepted by the learning module 1103 to improve the system. For example, if assets move with regular patterns or if obstruction appear on scheduled times these behaviors and their solutions could be rapidly implemented by the improvement routine 1113 at the outset of the implementation of the system.
It is contemplated that the system could have the ability to adapt its own performance. Referring to FIG. 8, an optimizer 1213 monitors the usage of power consumption by a transmitter 1201 and a gateway 1203. The transmitter is be powered by a first solar cell 1205 or a first battery 1207, likewise the gateway 1203 is be powered by a second solar cell 1209 or a second battery 1211. The optimizer 1213 adjust the power consumption of the transmitter 1201 and to a specific transmit strength or broadcast frequency so that the system network becomes synchronized thereby so that transmitter and the gateway communicate with a minimum of power.
The particular embodiments disclosed above are illustrative only, as the embodiments may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application. Accordingly, the protection sought herein is as set forth in the description. Although the present embodiments are shown above, they are not limited to just these embodiments, but are amenable to various changes and modifications without departing from the spirit thereto.
