Patent number: 11941978Abstract: Traffic signal timing plans are derived from vehicle trajectory or probe data. The probe data is collected and archived in a datastore over a sample time on the order of weeks or longer. Probe data is corrected for clock drift, geo-fence filtered to a selected intersection, and then stop line crossings in the intersection are identified and analyzed along with related data to determine the timing plans and schedule for the intersection. In this way, access to government agency timing plans is obviated so as to save time and expense.Type: GrantFiled: September 17, 2022Date of Patent: March 26, 2024Assignee: TRAFFIC TECHNOLOGY SERVICES, INC.Inventors: Justin Michael Neill, Brandon Keith Sams, Jonah Aaron Pincetich, Darryl Joseph Michaud, Thomas Bauer, Jingtao Ma

Publication number: 20240044230Abstract: An initiator circuit for a perforating gun includes a microprocessor structured to perform a circuit-startup algorithm comprising determining whether the circuit supply voltage is stable enough for operation and, if it is, or if a predetermined period of time has passed since powering up the circuit, sending a message indicating the circuit (and thus gun) is ready for operation. The sent message may be a communication uplink indicating an address of the circuit and its ready state or a short burst of pulses indicating the circuit's ready state.Type: ApplicationFiled: August 3, 2022Publication date: February 8, 2024Applicant: Probe Technology Services, Inc.Inventor: Roger Archibald

Patent number: 11746643Abstract: Various downhole logging tools and methods of using and making the same are disclosed. In one aspect a method evaluating cement bond quality in a well is provided. In a well with a particular casing/tubing configuration, waveforms of acoustic energy returning from the tubing and the casing with the tubing present are recorded. A frequency spectrum from the recorded waveforms is determined. Amplitudes of the returning acoustic energy at one or more preselected frequency(s) of interest of a range of frequencies at which the amplitudes are noticeably affected by cement bond quality for the particular casing/tubing configuration are determined. The determined amplitudes are compared with one or more baseline amplitudes to look for indications of cement bond quality. Other aspects involve time domain analysis.Type: GrantFiled: July 22, 2021Date of Patent: September 5, 2023Assignee: Probe Technology Services, Inc.Inventors: Jun Zhang, Yibing Zheng

Patent number: 10937313Abstract: At a roadway intersection controlled by an electronic traffic signal controller system, a potentially dangerous “dilemma zone” problem arises where a driver must quickly decide whether to stop or continue through the intersection. The problem is mitigated by leveraging data provided by an approaching vehicle itself as the source of detection. Based on the vehicle data itself, an “artificial detection” message is sent to the traffic signal controller to attempt to extend the green time, and thus permit a subject vehicle to safely pass through the intersection.Type: GrantFiled: December 5, 2019Date of Patent: March 2, 2021Assignee: TRAFFIC TECHNOLOGY SERVICES, INC.Inventors: Jingtao Ma, Thomas Bauer

Patent number: 10878693Abstract: Methods and systems to improve the accuracy of traffic signal state change predictions are disclosed. Predictions can be broadcast to vehicle drivers or autonomous systems to improve safety, fuel efficiency and reduce delays. Predictions for fixed-time signals are generated based on their scheduled timing plan and the current clock/time, but these predictions are subject variations, for example, due to traffic signal controller clock drift. Real-time actual, not predicted, data is collected and utilized to correct for these variations. Further, real-time probe data is collected and used to validate correctness of the generated predictions in real time. In one embodiment, GPS data from travelers' devices is utilized to assess validity of the generated predictions, looking particularly at signal stop line crossings relative to predicted green time window. If crossings observed in real time contradict the predicted signal state, the data service providing predictions to users may be suspended.Type: GrantFiled: October 22, 2019Date of Patent: December 29, 2020Assignee: TRAFFIC TECHNOLOGY SERVICES, INC.Inventors: Jingtao Ma, Thomas Bauer, Kyle Zachary Hatcher, Alex Thomas Marineau
