Abstract

A Bluetooth Low Energy (BLE) Device providing location information via satellite geolocation technology (GNSS) using GPS, GLONASS, or similar, to a receiving device such as a smartphone. Alternatively the device uses a digital compass or gyroscope to determine location. The BLE device uses a low powered beacon protocol, without pairing with the receiving device. In various embodiments the device may be charged wirelessly, or via a physical connection such as a USB socket, or may be powered via a power source such as coin cell batteries.

Description

Back Ground Bluetooth Low Energy (BLE) devices can be used as tags and locating beacons to enable users to detect track and sense the conditions of their assets and their environment. BLE tags are generally battery powered and are paired to the user's mobile phone, the constant exchange of information required by the pairing method drains the batteries of both the tag and the phone during this process. The embodiment of this invention uses non pairing beacon only communication which when combined with further operational modes drastically reduces the power drain on the system.
The existing method of locating BLE devices is via their beacon, in order to achieve this quickly a fast beaconing rate must be used, and this results in substantial power drain and dramatically reduces the battery life of the product. An approach to reduce this effect is to beacon only on movement, this can be helpful if your asset is moving, however if the asset is static this does not work.
The searching device reports the associated power it receives from the target device, this can be in the form of RSSI (Received signal strength Indicator) or in dB.This value does not provide an exact location because it does not include any form of directional information. The embodiment of this invention provides extremely accurate location of the target BLE device without the power draining penalties of existing methods.
The unique combination within the embodiment of this invention is low power operation of the BLE devices with the increased locational accuracy.
Description of the Embodiment
The embodiment of this invention operates using a beacon only protocol which use substantially less power than pairing. Furthermore due to the novel mode of operation within the embodiment it can be put into a state where it beacons at its predetermined rate without having to be driven from the microprocessor (uP). This state allows the uP and ancillary components to remain in their lowest power configuration greatly reducing battery drain.
Within this Non paired autonomous transmit state the device can also receive additional data from a other BLE devices within range, this in turn can be used as the trigger for the target device to perform additional sensory and or location measurements.
The RSSI locational information is non directional and can best be described as concentric rings moving outwards from the BLE device, any receiving BLE device at the same distance from the transmitting device will read the same RSSI figure 1.
The embodiment of this invention can use a plurality of location technologies, the following are examples of which.
1) The embodiment can include an electronic Gyroscope and or an electronic compass, the coordinates from which can be transmitted via the embodiments beacon back to any BLE receiving device. The receiving device can compare the coordinates with its own and when combining them with the RSSI can use this to deduce the bearings of the beaconing device, figure 2.
2) One of the most accurate location technologies is GNSS (GPS). These systems use large amounts of power when they are acquiring their initial Satellite fix, this first fix is known as a cold start and can typically take 30 seconds, data collected during a cold start is known as the ephemeris data. Once acquired the GNSS system power requirements normally halve, even so the power requirement for operating a GNSS unit within the embodiment would consume an order of magnitude more current if operated in this manner. Using its unique beaconing low powered beaconing protocol the embodiment can provide locational information when a request is sent to it from another BLE device. This request can include the ephemeris data which enables the embodiment to perform a hot start which typically takes 1 second and by comparison uses 50 times less power than a cold start.
