Patent number: 11921192Abstract: Systems and methods for locating radiofrequency identification (RFID) tags are described. In one embodiment, radiofrequency (RF) signals are transmitted from one or more RFID readers, and in accordance therewith, backscattered signals are received from a tag to be located. A plurality of measured position parameters are used to determine a location of the tag. In one embodiment, one reader may transmit and three readers may receive signals to determine the position of a tag. In other embodiments, multiple readers may transmit and receive. In another embodiment, one reader may transmit from different positions to locate a tag. Embodiments of the invention may be used to track a moving tag. A reader's position may be determined using GPS, reference tags, or the reader may be positioned in a known location. A map may be provided to a user to display the location or movement of a tag or a corresponding item.Type: GrantFiled: March 11, 2021Date of Patent: March 5, 2024Assignee: Innovo Surgical, Inc.Inventors: Kambiz Shoarinejad, Maryam Soltan, Mehran Moshfeghi

Publication number: 20230375688Abstract: Techniques described here introduce signature frequency modulation to unmodulated pulse signals as frequency chirps to enhance the security of multi-carrier phase-based ranging signals. The characteristics of the chirps may be mutually known by an initiator and a desired reflector of the ranging applications. The characteristics of the chirps may vary between the multi-carrier signals to thwart any attempt by an eavesdropper to predict the chirps. In one aspect, the characteristics of the chirps may be calculated for each timeslot of a ranging cycle by two authorized devices using a ciphering algorithm such as the Advanced Encryption Standard (AES) based on a shared security key. Each call of the AES may generate one or more pseudo-random numbers based on the shared security key and a time-varying initialization vector that increments every timeslot. Fields of the pseudo-random number may be extracted to determine the characteristics of the chirps associated with the timeslot.Type: ApplicationFiled: May 19, 2022Publication date: November 23, 2023Applicant: Cypress Semiconductor CorporationInventors: Nozhan HOSSEINI, Pouria ZAND, Kiran ULN, Claudio REY, Kambiz SHOARINEJAD

Patent number: 8912954Abstract: A multi-standard single chip integrated within a multi-standard mobile device concurrently receives multi-standard radio frequency signals by corresponding two or more integrated radios. The multi-standard single chip generates full GNSS measurement comprising pseudo-range information using the received radio frequency signals. The multi-standard single chip comprises a GNSS radio and multiple non-GNSS radios such as Bluetooth. The full GNSS measurement is generated using GNSS radio frequency signals received by the integrated GNSS radio and communicated over, for example, Bluetooth radio. GNSS satellite reference information embedded in radio frequency signals received by the integrated non-GNSS radios is extracted to assist the full GNSS measurement. A full GNSS navigation solution for the multi-standard mobile device is generated internally to and/or externally to the multi-standard single chip depending on the location of a navigation engine.Type: GrantFiled: September 14, 2012Date of Patent: December 16, 2014Assignee: Broadcom CorporationInventors: John Walley, Charles Abraham, Evan McCarthy, Kambiz Shoarinejad
