Publication number: 20240107260Abstract: An approach to obtain low latency association of the audio clock in a smartphone with an incoming RF message is to use an interrupt driven routine, where the receipt of the RF message preamble generates an interrupt that reads the audio clock counter since the start of the audio session. In some embodiments such an approach may be implemented on the specialized processing cores found in smartphones that control RF communication, sensor or audio processing.Type: ApplicationFiled: August 8, 2023Publication date: March 28, 2024Applicant: Sonitor Technologies ASInventors: Wilfred Edwin Booij, Kjetil HASLUM, Fritjof Boger ENGELHARDTSEN, Endre BAKKA

Patent number: 11867826Abstract: The present disclosure relates to an acoustic position determination system that includes a mobile communication device and at least one base transmitter unit. The mobile communication device is configured to identify a peak in the received signal, and to de-convolve the signal with all codes that are relevant to the area in which the signal is received. A joint likelihood that a potential code is correct is formed by determining a likelihood based on a signal parameter such as signal-to-noise ratio and a likelihood based on time-of arrival information.Type: GrantFiled: October 25, 2022Date of Patent: January 9, 2024Assignee: Sonitor Technologies ASInventors: Wilfred Edwin Booij, Cyril Antille, Endre Bakka, Magnus Oplenskedal

Patent number: 11860261Abstract: A communication device including a clock, a memory, and at least one processor is disclosed. The at least one processor is configured to execute instructions stored in the memory that cause the at least one processor to perform operations including receiving at least one message from a second communication device of a plurality of communication devices over a preconfigured time duration, determining a first local time of the clock of the communication device at which the at least one message from the second communication device is received, and determining a sync-time of the second communication device based on the at least one message from the second communication device. The operations include mapping the sync-time of the second communication device based on the first local time and the determined sync-time of the second communication device and adjusting a sync-time of the communication device based on the second local time.Type: GrantFiled: September 6, 2022Date of Patent: January 2, 2024Assignee: Sonitor Technologies ASInventors: Endre Bakka, Wilfred Edwin Booij

Publication number: 20230319523Abstract: The present disclosure relates to a location determination system that includes acoustic transmitting devices, location tags, and a wireless mesh network, where the wireless mesh network uses battery-powered devices. A location tag receives acoustic signals (e.g., ultrasound signals) from an acoustic transmitting device. Clocks from members of the wireless mesh network are synchronized by observation of clock pairings, each clock pair formed by respective clocks in a transmitting device that transmits a message and a receiving device that receives the message. By analyzing the observed clock pairings, a best fit between the clock pairings may be determined. After selecting a reference clock, an acoustic transmission schedule may be propagated to the respective acoustic transmitting device.Type: ApplicationFiled: January 31, 2023Publication date: October 5, 2023Applicant: Sonitor Technologies ASInventors: Wilfred Edwin Booij, Endre Bakka

Publication number: 20230292088Abstract: A method for determining proximity comprises sending a wireless signal from a first mobile tag (120a) of a plurality of mobile tags (120), the wireless signal communicating identification information associated with the first mobile tag (120a). The wireless signal is received at a second mobile tag (120b) of the plurality of mobile tags (120), and proximity data comprising the identification information is stored in a memory (127b) of the second mobile tag (120b). The proximity data is sent from the second mobile tag (120b) to a mobile communication device (110) using a first wireless protocol, is received at a mobile communication device (110), and is stored in a memory (117) of the mobile communication device (110). The proximity data is sent from the mobile communication device (110) to a server (130) using a second wireless protocol, and the proximity data is stored in a memory (137) of the server (130).Type: ApplicationFiled: July 2, 2021Publication date: September 14, 2023Applicant: Forkbeard Technologies ASInventors: Mattheus Franciscus Albertus Ten Veldhuis, Endre BAKKA, Cyril ANTILLE, Wilfred Edwin BOOIJ

Publication number: 20190204403Abstract: The present disclosure relates to a location determination system that includes acoustic transmitting devices and mobile devices. A mobile device receives acoustic signals (e.g., ultrasound signals) from an acoustic transmitting device. The mobile device must be able to identify the acoustic transmitting device with particularity when receiving the acoustic signals. It is more efficient to use a short identifier, for example 6 bits, for this purpose because it requires less power to transmit and decode. By utilizing the rotating identifier system described herein, more acoustic transmitting devices can be distinguished than using a time-invariant identifier would otherwise provide, and the transmissions are more secure and therefore less vulnerable to free-riders.Type: ApplicationFiled: December 29, 2017Publication date: July 4, 2019Applicant: Sonitor Technologies ASInventors: Wilfred Edwin BOOIJ, Endre BAKKA, Fritjof Boger ENGELHARDTSEN
