Patent number: 11968601Abstract: A method includes, generating a schedule for an asset tag, the schedule defining: a unicast trigger time for transmission of a unicast trigger to the asset tag; a transmit time succeeding receipt of the multicast trigger; and a wake window intersecting the transmit time and the receipt of the multiact trigger. The method also includes transmitting the schedule from a node network to the asset tag and configuring the asset tag based on the schedule. The method also includes, at the node network, broadcasting the unicast trigger and, at an asset tag: entering a wake mode; receiving the unicast trigger; transmitting a ranging signal; and entering the sleep mode. The method further includes, at the node network: deriving location of the asset tag based on instance of the ranging signal received by nodes in the node network.Type: GrantFiled: April 20, 2023Date of Patent: April 23, 2024Assignee: ZaiNar, Inc.Inventors: Alexander Feldman, Phillip B. Hess, Philip Adam Kratz, Srdjan Miocinovic, Jonathan Shiao-En Lu

Publication number: 20230379666Abstract: A method includes, generating a schedule for an asset tag group, the schedule defining: a multicast trigger time for transmission of a multicast trigger to the asset tag group; and for each asset tag in the asset tag group, a transmit time succeeding receipt of the multicast trigger and unique to the asset tag, and a wake window intersecting the transmit time and the receipt of the multiact trigger. The method also includes, at the node network: broadcasting the multicast trigger; and, at an asset tag in the asset tag group, entering a wake mode; receiving the multicast trigger; transmitting a ranging signal; and entering the sleep mode. The method further includes, at the node network: receiving ranging signals from the asset tag group; and deriving locations of the asset tags in the asset tag group based on the ranging signals received by the node network.Type: ApplicationFiled: April 20, 2023Publication date: November 23, 2023Inventors: Alexander Feldman, Phillip B.

Patent number: 11212015Abstract: Methods, systems, and computer program products are described for automatically reducing interference within received signals. A first radio frequency (RF) signal having (i) a desired component and (ii) an interference component with a noise component and a jammed component is received. A trained machine learning (ML) model extracts, from the RF signal, the jammed component and a portion of the noise component. The trained ML model generates and outputs a second RF signal comprising the desired component and a reduced noise component. The reduced noise component has the portion of the noise component removed. The jammed component is removed from the second RF signal.Type: GrantFiled: May 19, 2020Date of Patent: December 28, 2021Assignee: THE AEROSPACE CORPORATIONInventors: Phillip B. Hess, Andres I.

Patent number: 10491251Abstract: Circuits and methods are described herein for suppressing interference in binary offset carrier (BOC) modulated signals The BOC signal includes an upper sideband (USB) and a lower sideband (LSB). The LSB or the USB of the BOC signal is rotated from a first frequency to a second frequency. Interference in the rotated LSB or USB is reduced. An output BOC signal with reduced interference is generated based on the rotated LSB or USB from which interference has been reduced.Type: GrantFiled: December 5, 2018Date of Patent: November 26, 2019Assignee: The Aerospace CorporationInventors: Philip A.

Patent number: 8588724Abstract: A system and method for improving the processing of communications signals received in the presence of narrowband interference signals. The received communications signals are time sampled and transformed into a series of spectral terms in the frequency domain that are then evaluated to identify narrowband interference signals. The identified narrowband interference terms can be calculated to a value that will optimize the corrupted spectral terms resulting from the communication, and an inverse transformation can be used to generate a time domain signal that is free from interference.Type: GrantFiled: August 19, 2010Date of Patent: November 19, 2013Assignee: Alfred E.

Patent number: 8099647Abstract: An apparatus, system and method can be arranged for coding and/or decoding with a phase invariant coding scheme that is useful for short burst signaling devices. 10-bit data is mapped into a 12-bit data with a non-coherent burst code mapper. A parity generator creates a 12-bit parity data to form a 24-bit extended binary Golay code from the 12-bit data. The values for selected bit fields in the 12-bit data and 12-bit parity data are swapped to generate I and Q data such that sensitivity to changes in rotational phase is removed. I and Q data can be used by a transmitter to transmit a rotationally-invariant signal. On receipt, I and Q signals can be recovered, reverse swapped to generate the parity and data signals, and remapped to recover the transmitted 10-bit data. The receiver can also be arranged to use a soft decoding method for improved signal integrity.Type: GrantFiled: February 17, 2010Date of Patent: January 17, 2012Assignee: Alfred E.

The programmable telemetry circuit may include a first coil; a high impedance path having a first node connected to a first node of the first coil; a low impedance path having a first node connected to the first node of the first coil; a capacitive path having a first node connected to a second node of the first coil; and an input path for coupling signals into the high impedance path, the low impedance path, and the capacitive path. The low impedance path may be connected in parallel with the high impedance path. The capacitive path may form a circuitous path with the high impedance path and the low impedance path. The programmable circuit may be programmed to select the high impedance path or the low impedance path.Type: GrantFiled: October 30, 2007Date of Patent: August 23, 2011Assignee: Medtronic Minimed, Inc.Inventors: Wayne Morgan, Phillip B.
