Patent number: 11933873Abstract: One example includes a passive radar receiver system including an RF receiver front-end to receive a wireless source signal and a reflected signal. An antenna switch of the front-end switches a first antenna to a receiver chain during a first time to generate first radar signal data based on a combined wireless signal comprising wireless source signal and the reflected signal, and switches a second antenna to the receiver chain during a second time to generate second radar signal data based on the combined wireless signal. A signal processor generates source signal data associated with the wireless source signal based on the first and second radar signal data and generates reflected signal data associated with the reflected signal based on the first and second radar signal data, and generates target radar data associated with a target based on the source and reflected radar signal data.Type: GrantFiled: March 16, 2022Date of Patent: March 19, 2024Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Yaron Alpert, Matan Ben-Shachar, Anand Ganesh Dabak, Brian Ginsburg

Publication number: 20240064640Abstract: A device (e.g., an IoT device) includes a first radio, and a memory device accessible to the first radio. The memory device is configured to store a fingerprinting feature for a specific transmitter device. A second radio and a processor are also included. The process is coupled to the first and second radios. The first radio is configured to extract a fingerprinting feature of a first received wireless signal, determine that the extracted feature matches the fingerprinting feature stored in the storage device, and responsive to the determination that the extracted feature matches the feature stored in the storage device, cause the second radio to transition from a lower power state to a higher power state of operation and continue to receive the incoming signal.Type: ApplicationFiled: October 31, 2023Publication date: February 22, 2024Inventors: Yaron ALPERT, Matan BEN-SHACHAR, Oren Aharon SHANI

AVOIDING MEDIA ACCESS CONTROL PADDING OF TRIGGER-BASED PHYSICAL LAYER CONVERGENCE PROTOCOL DATA UNIT
Publication number: 20230308945Abstract: A wireless station (STA) in a wireless local area network (WLAN) performs a method to avoid media access control (MAC) padding of a physical layer convergence protocol data unit (PPDU) (e.g., a trigger-based (TB) PPDU, etc.). The method can reduce current or power consumption by the STA, which can in turn optimize the STA and, in certain instances, the WLAN as whole. In one example, the method includes the STA receiving a trigger frame from an access point (AP). The trigger frame specifies a length of a PPDU. The method further includes the STA generating a TB PPDU based on the specifications in the trigger frame. In particular, the STA generates a PPDU that has a length that is less than the length specified by the trigger frame. The method also includes the STA transmitting the generated PPDU to the AP.Type: ApplicationFiled: June 1, 2023Publication date: September 28, 2023Inventors: Oren Aharon SHANI, Shai EREZ, Matan BEN-SHACHAR -

Publication number: 20230055972Abstract: A Fine Time Measurement (FTM) authentication system and method include performing a FTM transaction comprising at least one FTM-ACK message pair transmitted and received via a first communication channel between two endpoints, where the at least one FTM-ACK message pair contains timestamp values of message departure time and message arrival time during the FTM transaction. At least one authenticating value indicative of timestamp values of the at least one FTM-ACK message pair arrival and departure times during the FTM transaction is then transmitted via a second communication channel. FTM timestamp values are recovered from the received at least one authenticating value, which are compared with the received FTM timestamp values. The received FTM timestamp values can be authenticated if there is a match between the recovered FTM timestamp values and the received FTM timestamp values.Type: ApplicationFiled: August 18, 2021Publication date: February 23, 2023Inventors: Matan Ben-Shachar, Oren Shani, Yaron Alpert

Publication number: 20200382934Abstract: A network device serving two or more networks using periodic times slots for transmission events is configured to determine that one of the periodic time slots on one of the networks has or soon will collide with one of the periodic time slots on the other network by processing time stamps for events on each network. Either of the periodic time slots may be occasionally shifted by a time shift amount to avoid a collision between the periodic time slots on each network. Shifting the periodic time slots may be performed by transmitting a Bluetooth connection parameter update packet.Type: ApplicationFiled: June 15, 2020Publication date: December 3, 2020Inventors: Matan Ben-Shachar, Omri Eshel, Yuval Jakira, Liran Brecher, Dotan Ziv, Chen Loewy
