Patent number: 11921187Abstract: Techniques for monitoring devices to use ultrasonic signals to detect and track the locations of moving objects in an environment. To determine distance information, the monitoring devices emit a frequency-modulated continuous wave (FMCW) signal at an ultrasound frequency range. Reflections of the FMCW ultrasonic signal are used to generate time-of-arrival (TOA) profiles that indicate distances between the monitoring device and objects in the environment. The reflections can be processed to suppress undesirable interferences, such as reflections off non-mobile objects in the environment (e.g., walls, furniture, etc.), vibrations off the floorings or the ceilings, etc. After processing the reflections, a heatmap can be used to plot the intensity of the reflections for the different TOAs of the reflections, and depict the movement of the user over time. Finally, a Kalman filter is used to smooth the peaks in the intensity values on the plot, and determine the trajectory of the human.Type: GrantFiled: April 16, 2021Date of Patent: March 5, 2024Assignee: Amazon Technologies, Inc.Inventors: Spencer Russell, Krishna Kamath Koteshwara, Tarun Pruthi, Trausti Thor Kristjansson, Anran Wang

Patent number: 7558251Abstract: A broadband communication system including an Internet Protocol Telephony Network and public switched telephone network, including apparatus and methods for placing a call on hold in a way that significantly reduces the amount of network bandwidth utilized by the call while the call is on hold. When a call is placed on hold, embodiments of the architecture of the telephony network of the present invention allows the network to essentially “forget” about the call placed on hold. In other words, a call that is on hold may require very little, or even zero, bandwidth within the telephony network. Accordingly, the total necessary bandwidth capacity of the telephony network may be smaller than it would be if calls on hold were to consume precious network bandwidth as is found in existing telephony systems.Type: GrantFiled: September 14, 2004Date of Patent: July 7, 2009Assignee: AT&T Intellectual Property II, L.P.Inventors: Laura Huang, Fen-Chung Kung, Jesse Eugene Russell, Hopeton Walker, Spencer Wang
