Patent number: 11933877Abstract: A system and method for locating radio-frequency identification tags within a predetermined area. The method can incorporate sub-threshold superposition response mapping techniques, alone, or in combination with other methods for locating radio-frequency identification tags such as but not limited to time differential on arrival (TDOA), frequency domain phase difference on arrival (FD-PDOA), and radio signal strength indication (RSSI). The system can include a plurality of antennas dispersed in a predefined area; one or more radio-frequency identification tags; a radio-frequency transceiver in communication with said antennas; a phase modulator coupled to the ra-dio-frequency transceiver; and a system controller in communication with said transceiver and said phase modulator. Calibration techniques can be employed to map con-structive interference zones for improved accuracy.Type: GrantFiled: December 14, 2022Date of Patent: March 19, 2024Assignee: Automaton, Inc.Inventor: Spencer Hewett

Publication number: 20240046211Abstract: A radio-frequency identification (RFID) tag reader interrogates RFID tags and detects their replies. These replies may propagate along direct or line-of-sight paths from the tags to the reader. They may also propagate along indirect or non-light-of-sight paths from the tags to the reader, e.g., by reflecting off nearby objects to the reader. As a result, the reader receives many copies of each tag's reply, with each copy arriving at a delay and angle corresponding to the path that it followed from the tag to the reader. The aggregate or combination of the detected replies is called a multipath profile or signature. Each tag/reader pair produces its own multipath profile. Moving objects near the reader and tag can change that multipath signature by introducing or removing reflections along a given path between the reader and tag. These changes can be used to determine that an object has moved, even if that object does not have an RFID tag.Type: ApplicationFiled: October 19, 2023Publication date: February 8, 2024Applicant: Automaton, Inc.Inventors: Spencer Hewett, Paul Petrus

Patent number: 11408965Abstract: A radio frequency identification (RFID) system includes an array of antennas to distinguish line-of-sight (LOS) paths from non-line-of-sight (NLOS) paths. The distance between adjacent antennas in the array of antennas is less than half the wavelength of the radio frequency (RF) signal of the system. Each antenna in the antenna array is also digitally controlled to change relative phase difference among the antennas, thereby allowing digital steering of the array of antennas across angles of arrival (AOAs) between 0 and ?. The digital steering generates a plot of signal amplitudes as a function of AOAs. LOS paths are distinguished from NLOS paths based on the shapes (e.g., depth, gradient, etc.) of local extremes (e.g., maxima or minima) in the plot.Type: GrantFiled: December 17, 2019Date of Patent: August 9, 2022Assignee: Automaton, Inc.Inventors: Spencer Hewett, Adam Blair, Ken Seiff, Michael Murphy, Mark Wieman, Tamara Adlin

Publication number: 20050080799Abstract: A system for collecting and distributing information to and from a plurality of electronically controlled machines. The system is designed to collect information from robots, industrial machines, and other types of equipment that produce real-time information. The machines are coupled to a data collector module using a public domain communication protocol. The data collector module is coupled in data communication to a main server which has a mechanism for publishing the data received from the electronically controlled machines over a network to one or more clients. The main server also has an authenticator for verifying the identity of clients accessing the system through the network, and a communication module for streaming the data from the electronically controlled machines. Information and programming may also be transferred from the clients to the machines through the system to allow remote control of the machines.Type: ApplicationFiled: October 18, 2004Publication date: April 14, 2005Applicant: ABB Flexible Automaton, Inc.Inventors: James Harnden, James Winfree, Mark Hornick, John Borchardt, Mark Skerencak, Robert Gehred
