Publication number: 20220286336Abstract: Improved approaches for use of RF signals (e.g., OFDM signals) for determining a range that can be used for geolocation of a device. The disclosure includes systems and methods that may allow for transition from a correlation approach to a group delay approach. In addition, upon detection of the presence of multipath error in a signal, a signal bandwidth may be increased to as to include additional position reference symbols (PRS) that are included in a determination of a propagation delay, and in turn, a range. In addition, use of a different number of symbols in a signal based on signal SNR is presented.Type: ApplicationFiled: August 24, 2020Publication date: September 8, 2022Inventors: RICHARD M.

Publication number: 20210234882Abstract: Interactive interfaces and data structures representing physical and/or visual information are provided using smart pins (also called “pins” herein). Pins representing vectors of information may be provided. For instance, in the context of cybersecurity, each pin may represent an attack vector that an adversary can use to attack a system. Each pin may have a depth meter and may move up or down according to its value in an operating range. Each pin may also have a color, a number, or both, representing its current value in the operating range. Such pins may provide both a three-dimensional representation of data that is intuitive to users.Type: ApplicationFiled: January 24, 2020Publication date: July 29, 2021Applicant: The Aerospace CorporationInventor: Richard M.

Patent number: 10365376Abstract: Positioning, navigation, and timing (“PNT”) signals, such as those used in GNSS or LORAN systems, may be vulnerable to spoofing attacks. To generate trustworthy time and location data at a receiver, one must at least reduce the likelihood of or be capable of detecting spoofing attacks. Embodiments of the present invention, as presented herein, provide solutions for detecting spoofing of PNT signals. Various aspects incorporated into the described embodiments which assist in detecting spoofing attacks may include but are not limited to: monitoring the SNR of received PNT signals of a first modality and switching over to an alternate PNT modality when an anomaly is detected, comparing data associated with signals of multiple PNT modalities to identify a discrepancy indicative of spoofing on one of the multiple PNT modalities, and implementing a security regime to prevent spoofers from being able to produce perceivably authentic, but corrupt, replica signals of a PNT modality.Type: GrantFiled: April 25, 2018Date of Patent: July 30, 2019Assignee: iPosi, Inc.Inventors: Richard M.

Patent number: 10274602Abstract: Determination of a signal loss profile relative to a receiver based on measured signal power of a sounding signal from a sounding transmitter having a known signal power in free space relative to the receiver. The signal loss profile may include a plurality of signal loss values corresponding to a plurality of received sounding signals at the receiver. In an embodiment, the sounding signal may comprise a GNSS navigational signal (e.g., a GPS signal). The signal loss profile may be used to extrapolate signal loss for a transmitter collocated with the receiver. In turn, the signal loss profile may be used in conjunction with a shared spectrum system to model a signal propagation from the collocated transmitter when determining allocation of a shared spectrum resource of the shared spectrum system.Type: GrantFiled: July 14, 2015Date of Patent: April 30, 2019Assignee: iPosi, Inc.Inventors: Richard M.

Patent number: 10185036Abstract: Data bandwidth reduction in positioning system signals. Specifically, a first, relatively easily acquired signal may be analyzed to determine if and/or to what extent to decimate a second signal. The second signal may comprise a higher encoded data rate (e.g., a chip rate). In turn, decimation of the second signal based on characteristics of the first signal may allow for more efficient processing of the second signal.Type: GrantFiled: February 16, 2018Date of Patent: January 22, 2019Assignee: iPosi, Inc.Inventors: Richard M.

Patent number: 9766338Abstract: A GNSS cooperative receiver system that can be utilized when one or more GNSS receivers is in a compromised position where it cannot receive direct signals from a sufficient number of GNSS satellites. This may in the interior of an office building or multi-dwelling unit, which may be in the vicinity of other tall buildings. The receivers determine their relative positions from one of various ranging techniques, and then with this relative position information, pseudoranges, and correlation values from the various GNSS receivers, the best GNSS solution can be determined for the group of cooperative receivers. This could include two or more receivers in a group. There also related techniques for one receiver to be a designated, remote anchor for other GNSS receivers that need such assistance.Type: GrantFiled: March 2, 2015Date of Patent: September 19, 2017Assignee: iPosi, Inc.Inventors: Christopher Neil Kurby, Richard M.

Patent number: 9715017Abstract: Techniques for allowing a remote or fielded receiver to derive a precise time reference (such as Coordinated Universal Time (UTC)) when the fielded receiver is not able to derive time directly from received GPS signals. One or more fixed DME reference stations are located within range of DME beacon signals from an existing DME beacon station, the DME reference stations also having the capability to receive GPS signals and derive UTC therefrom. Based on the known distance between the DME reference station and the DME beacon station, the DME reference station can determine the time of transmission from the DME beacon station of each DME beacon signal. This time tag information is then provided to the fielded receiver, which is also within range of DME beacon signals from the DME beacon station. With this time tag information, the fielded receiver can correlate that with the received DME beacon signals and derive UTC to within an acceptably small margin.Type: GrantFiled: March 4, 2016Date of Patent: July 25, 2017Assignee: iPosi, Inc.Inventors: Richard M.

Patent number: 9661134Abstract: A method and system for precise position determination of general Internet Protocol (IP) network-connected devices. A method enables use of remote intelligence located at strategic network points to distribute relevant assistance data to IP devices with embedded receivers. Assistance is tailored to provide physical timing, frequency and real time signal status data using general broadband communication protocols. Relevant assistance data enables several complementary forms of signal processing gain critical to acquire and measure weakened or distorted in-building Global Navigation Satellite Services (GNSS) signals and to ultimately extract corresponding pseudo-range time components. A method to assemble sets of GNSS measurements that are observed over long periods of time while using standard satellite navigation methods, and once compiled, convert using standard methods each pseudo-range into usable path distances used to calculate a precise geographic position to a known degree of accuracy.Type: GrantFiled: January 23, 2013Date of Patent: May 23, 2017Assignee: iPosi, Inc.Inventors: Richard M.

Patent number: 9656795Abstract: A method of shipping at least one child-resistant medicate container via a carrier includes providing or obtaining at least one child-resistant medicate container including a front sidewall, and an opposing rear sidewall, a right sidewall, an opposing left sidewall, and at least one locking mechanism. The method also includes creating or obtaining a flat-rate shipping package from a carrier, inserting the at least one child-resistant medicate container into the package, and closing the package to enclose the at least one child-resistant medicate container within the package so that the package is generally flat and acceptable by the carrier for a flat-rate shipping. The method also includes causing the closed package to be shipped or transported by the carrier at a flat-rate.Type: GrantFiled: May 29, 2013Date of Patent: May 23, 2017Assignee: Juno Technologies, LLCInventors: Thomas Guschke, Richard M.
