Abstract: A system incorporating a watchdog and power throttling capability which is implemented to ensure that network devices do not consume their entire battery capacity prior to the minimum expected battery life associated with the battery/device. The system includes capabilities for monitoring predicted remaining battery life in each associated device as well as the ability to control various functionalities within the device and the timing of events so as to guarantee minimum operating life for the device. This watchdog/throttling capability is implemented in such a way as to minimize the impact to device behavior and system operating parameters as much as possible while still enforcing minimum device/battery lifetime.

Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular access point (AP). Such implementation includes determining a coordinate location of the EN based on position information for multiple reference points (RPs) and a time of flight (TOF) of an ultrasonic waveform transmitted by each of the RPs.

Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular access point (AP). Such implementation includes determing a location of the EN based on position information for multiple reference points (RPs), which may in instances be supplied by the AP. Advantageously, the relative positioning is more particularly based on the received signal strengths (RSS) of beacon advertisement messages broadcast from the RP's, and refined by each of the position information.

Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of establishing a connection between a particular EN and a particular access point (AP). Such implementation includes determining such connection based on a relative proximity of an EN to an AP, and a relative value of the connection between an EN and an AP. Accordingly, a relative location of the EN may be determined based on such proximity.

Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and other components within the network. Such initiating is controllable by the network so as to effect a transfer of EN functionality among one or more of the other components. Implementation of the transfer depends on a network controlled timing determining functionality of all network components. Accordingly, the network is enabled to effect the power consumption of those components in an effort to optimize use of their respective power resources.

Abstract: Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular mobile access point (AP). Such implementation includes determining such connection based on a relative proximity of an EN to the mobile AP, and a relative value of the connection between an EN and the mobile AP. Accordingly, a relative location of the EN may be determined based on such proximity, and particularly in response to mobility of the AP.

Abstract: Provided are a system and method for geolocation of a tag relative to a predetermined threshold based upon receipt of duplicate beacon transmission for a same channel. In response to the duplicate transmission, the tag determines relative phase shift resulting from difference in path length, and evaluates correlation of a highest magnitude phase shift to the absence of any difference in path length to assess proximity of the tag with respect to the aforementioned predetermined threshold.

Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular access point (AP). Such implementation includes determining a location of the EN, in which that location is resolved by the EN and defined with respect to association with a reference point (RP) enabled to transmit an ultrasonic waveform serving as the primary basis for the location determination according to detection by the EN of a pseudo-random sequence derived from the MAC ID of the RP.

Abstract: Provided are a wireless communications system and method regarding geolocation of a tag based upon receipt of duplicate beacon transmission for a same channel. In response to the duplicate transmission, the tag determines relative phase shift for such transmission resulting from difference in path length, and correlates such difference to a coordinate location of the tag in a given space in which the wireless communications occurred.

Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular access point (AP).
