Patent number: 10708970Abstract: 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 location of the EN, in which that location is resolved by the EN and defined with respect to exchanges of Constant Tone Extensions (CTEs) between the EN and reference points (RPs).Type: GrantFiled: November 14, 2019Date of Patent: July 7, 2020Assignee: Link Labs, Inc.Inventors: Mark Bloechl, Ricardo Luna, Jr., Patrick Li, Brian Emery Ray

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.Type: GrantFiled: June 24, 2019Date of Patent: December 10, 2019Assignee: LINK LABS, INC.Inventors: Mark Bloechl, Ricardo Luna, Jr., Patrick Li, Brian Emery Ray

Patent number: 10499196Abstract: 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 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 RPs, and refined by each of the position information.Type: GrantFiled: November 1, 2018Date of Patent: December 3, 2019Assignee: LINK LABS, INC.Inventors: Mark Bloechl, Scott Wohler, Ricardo Luna, Jr., Patrick Li

Patent number: 10264436Abstract: 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) to be operable with a cellular backhaul and as the receiver of messaging generated by components within the network for the downstream cellular transfer of proximity and other types of information collected by the EN. The EN is configured to collect GPS and WiFi positional information determinative of a location of the EN, and transmit such positional information directly from the EN over an available backhaul so as to enable a determination of a relative location thereof based only on that positional information. In these ways, location and other types of information associated with the EN may become known with increased reliability and certainty in the face of obstacles such as structural barriers and distance that ordinarily limit BLE performance.Type: GrantFiled: May 29, 2018Date of Patent: April 16, 2019Assignee: LINK LABS, INC.Inventors: Scott Wohler, Mark Bloechl, Ricardo Luna, Jr., Patrick Li, Brian Emery Ray

Patent number: 10244377Abstract: 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.Type: GrantFiled: April 19, 2018Date of Patent: March 26, 2019Assignee: LINK LABS, INC.Inventors: Mark Bloechl, Scott Wohler, Ricardo Luna, Jr., Patrick Li, Brian Emery Ray

Patent number: 10244373Abstract: 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.Type: GrantFiled: June 17, 2017Date of Patent: March 26, 2019Assignee: LINK LABS, INC.Inventors: Mark Olden Bloechl, Ricardo Luna, Jr., Patrick Li, Brian Emery Ray

Patent number: 10237913Abstract: 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.Type: GrantFiled: March 21, 2018Date of Patent: March 19, 2019Assignee: LINK LABS, INC.Inventors: Scott Wohler, Mark Bloechl, Ricardo Luna, Jr., Patrick Li, Brian Emery Ray
