The Cloudleaf Inc invention works as followsThe system includes at least a battery-powered Bluetooth Low Energy enabled leaf-node device. This device is connected via BLE to the leaf-node. It creates a number of sectorized beams and collects data from the leaf-node device in at lease one of these sectors. A location processing facility then determines the location in real time of the leaf-node device using the data collected by this beam-forming reader-node.
Background for Systems, Methods and Devices for Asset Status Determination
The asset management system is software that continuously inputs real-time data, where each node is associated with a specific asset. It organizes the data in a coherent manner; offers methods for extracting useful information and knowledge; and provides potential methods for directing those nodes.
Asset management systems can be used to manage the manufacturing, storage, delivery, and other logistical aspects of physical goods.
The tracking of such goods is critical. It provides crucial information to controlling industrial entities, such as the current and historical location, the current and historical rate at which they are moving, the current and past state of those goods (such as humidity, temperature and shock), the current and previous state data regarding these goods.
Within the field of enterprise asset management, physical asset management includes various methods and systems that help various types of enterprises manage various physical and infrastructure assets, including in relation to design, construction, commissioning, operating, maintaining, repairing, modifying, replacing and decommissioning/disposal of such physical and infrastructure assets, which may include equipment, tools, structures, production and service plants, power generating assets, water and waste treatment assets, facilities, distribution networks, transport systems, buildings, inventory, supplies, vehicles, products, information technology systems, and a wide range of other physical assets. There are now information technology systems that help manage and catalog physical assets. These include systems for recording the locations of assets and systems that use networking technologies such as RFID and WiFi to collect and store certain data about assets.
The prior art in asset management systems fails to provide continuous, instantaneous access of all tracked states or to instantly inform operators of events requiring their attention.
The challenges of prior art Wi-Fi systems and RFID include: “Range, real time access to data, interference, scalability and physical constraints. Centralized control and power consumption is also a challenge.” Wi-Fi is a great choice for its decent range, and it has the right protocols in place at every level of the software stack. However, Wi-Fi requires a lot of power, making a system based solely on battery-powered Wi-Fi device unfeasible. RFID is limited by its range, as a reader has to be within range of the asset before it can retrieve information.
The above list is not exhaustive of all the shortcomings that an asset management system with BLE (hereafter “BLEATS”) can address. In embodiments, a BLEATs asset management system may comprise a software system that continuously inputs current real-time data such as from a set of computationally intelligent tags where each tag physically associates with some assets; coherently organizes these data; provides methods to extract useful information and knowledge from these data; and potentially provides methods to direct those tags. “In embodiments, a BLEATs Asset Management System may consist of a software that continuously inputs real-time current data, for example, from a set or computationally intelligent tags where each tag is physically associated with certain assets, coherently organizes this data, provides methods to extract valuable information and knowledge from this data and provides potential methods to direct these tags.
