Publication number: 20230117257Abstract: Methods and systems for improved detection of audio transmissions are provided. In one embodiment, a method is provided that includes receiving an audio signal containing an audio transmission. The audio transmission may contain a predetermined portion that was initially generated based on an expected sequence of complex-valued signals. A real portion of the expected sequence of complex-valued signals may be compared to the received audio signal to identify a first portion of the received audio signal. A complex portion of the expected sequence may be compared to portions of the received audio signal near the first portion of the received audio signal to identify a second portion of the received audio signal. An arrival time of the audio transmission may be determined based on the second portion of the received audio signal.Type: ApplicationFiled: December 22, 2022Publication date: April 20, 2023Inventors: Rebekah Farrar, Oz Mendel, William Knauer

Patent number: 11452153Abstract: A networkable device is coupled to a wireless IP gateway or paired to a personal area network (PAN) via the use of a sonic tone, which may be a human audible tone, which encodes a symbol sequence representing a binary message useful for implementing connection to a wireless IP gateway or pairing with a PAN. In one embodiment the sonic tone conveys a media access controller (MAC) address, to facilitate connection and/or pairing. Alternatively, or in addition, the sonic tone may encode a Service Set Identifier (SSID) and password for connection to a wireless network (Wi-Fi), or a BLUETOOTH (IEEE 802.15.1) identifier and/or PIN for connection to a BLUETOOTH (IEEE 802.15.1) PAN. In particular implementation of this embodiment the tone is produced by the IP gateway and used to initiate Wi-Fi connection, and/or the tone is produced by the master device of a PAN to initiate BLUETOOTH (IEEE 802.15.1) connection.Type: GrantFiled: January 8, 2018Date of Patent: September 20, 2022Assignee: LISNR, Inc.Inventors: William Knauer, Ian Andrew Birnam, Austin Andrew Teames, Joshua Matthew Glick, Rodney B.

Patent number: 11330319Abstract: A method of encoding, and decoding, a human-inaudible acoustic signal 240 embedded within audio content, suitable for use within the processor of an encoding and broadcasting system or a decoding and receiving system 200, 202. A binary message is encoded into a sequence 1000, 2000 of symbols selected from a group of four or eight symbols, each symbol encoding two or three binary bits with an associated frequency. The human-inaudible acoustic signal may have a variable length, with the length of the signal encoded in a header 1002-1008, 2002-2009. The encoding uses both forward error correction and cyclic redundancy coding to increase the robustness of the transmission. Furthermore, the binary bits encoded by the symbols are selected such that a Hamming distance of a single bit transformation exists between symbols associated with adjacent frequencies, so that a frequency error creates only a single bit error.Type: GrantFiled: October 15, 2015Date of Patent: May 10, 2022Assignee: LISNR, Inc.Inventor: William Knauer
