Patent number: 11733377Abstract: In an ultrasonic detection system that uses frequency-modulation or phase-modulation coding to distinguish emitted bursts from multiple transducers, a receiver associated with a transducer uses peak search, peak buffer, and peak rank stages in one or more receiver signal processing paths to identify valid received ultrasonic signal envelope peaks in correlator outputs. The peak rank stage can support different modes respectively designed to handle one code, two or more codes, or two or more codes with support for Doppler frequency shift detection. Valid peak information (e.g., amplitude and time) can be reported to a central controller and/or stored locally in a fusion stage to generate more intelligent information for targets or obstacles using peaks from multiple bursts.Type: GrantFiled: March 26, 2019Date of Patent: August 22, 2023Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Lei Ding, Srinath Mathur Ramaswamy, Anand Gopalan, Vaibhav Garg, Anand Ganesh Dabak, Baher S.

Patent number: 10979277Abstract: In described examples, a method of operating a transmitter includes generating a frequency reference signal having a reference frequency and outputting the frequency reference to a phase locked loop (PLL) that includes a voltage controlled oscillator (VCO). The VCO output is locked to the frequency reference signal to form a carrier signal. The transmitter receives an I input signal, a Q input signal, and a direct current (DC) leaky carrier signal. Either the I input signal or the Q input signal is added to the leaky carrier signal. The carrier signal is modulated with the resulting two signals using an I-Q mixer to generate a modulated signal that includes an unmodulated carrier signal component. The modulated signal is then transmitted.Type: GrantFiled: December 31, 2019Date of Patent: April 13, 2021Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Timothy Mark Schmidl, Swaminathan Sankaran, Gerd Schuppener, Salvatore Luciano Finocchiaro, Siraj Akhtar, Tolga Dinc, Anand Ganesh Dabak, Baher Haroun
