Patent number: 11501376Abstract: A vehicle route guidance computer system is configured to store habitual travel routes for drivers; detect driving by a vehicle of one of the drivers along one of the habitual travel routes; monitor vehicle location along the route; monitor traffic signal states and traffic conditions along the route; calculate an optimal velocity of the vehicle to maximize likelihood of reaching a next traffic signal along the route when the signal is green, and transmit a guidance signal to a guidance device in a vehicle to advise the driver to decelerate or accelerate the vehicle. The vehicle route guidance computer system may be further configured to detect an adverse condition along the route, calculate an alternative route, and transmit a direction guidance signal to the guidance device for guiding the driver to the alternative route.Type: GrantFiled: March 11, 2019Date of Patent: November 15, 2022Assignee: Hartford Fire Insurance CompanyInventors: Michael Louis Brandman, Raphael Jermaine Thomas

Patent number: 11486907Abstract: A monitoring device for monitoring an impedance of a protective conductor. The monitoring device has a first voltage divider for connection to a voltage source including a series connection to a first resistor and a second resistor. The second resistor has a resistance value which corresponds to a threshold value for the impedance of the protective conductor. A second voltage divider includes a series connection to a third resistor and a bridge diode and a connection to the first resistor at a first end of the third resistor and connectable to a second end of the third resistor and to the protective conductor. A measuring device is provided for the detection of a bridge voltage between a first node and a second node if the impedance of the protective conductor is greater than the value of the second resistor.Type: GrantFiled: March 15, 2019Date of Patent: November 1, 2022Assignees: TE Connectivity Germany GmbH, Heidelberger Druckmaschinen AGInventors: Stefan Kipp, Gregor Karrasch, Stefan Stross, Stefan Engert

Patent number: 11482108Abstract: A vehicle with an automatic accident report function. The vehicle includes a transmitter, a collector, a determiner, and a vehicle estimator. The transmitter automatically transmits, to a server apparatus, accident emergency information that is usable by the server apparatus to estimate injury of an occupant of the vehicle when an accident of the vehicle is detected or forecasted. The collector collects, in the vehicle, information of the vehicle involved in the accident. The determiner determines whether a communication environment is appropriate for transmission of the information from the transmitter to the server apparatus. The vehicle estimator estimates the injury of the occupant, using the information collected by the collector.Type: GrantFiled: July 26, 2021Date of Patent: October 25, 2022Assignee: SUBARU CORPORATIONInventor: Isamu Nagasawa

Patent number: 11452102Abstract: The various embodiments provide methods implemented in a multi-RF communication device for managing a victim subscription's de-sense by proactively implementing an RF coexistence management strategy on the victim subscription when an RF coexistence event starts. In various embodiments, a multi-RF communication device may implement an RF coexistence management strategy by determining when an aggressor subscription will de-sense a victim subscription and configuring the victim to anticipate and mitigate de-sense during the aggressor's transmissions. Thus, the various embodiments may provide dramatic improvements to the victim's overall reception performance and overall user experience.Type: GrantFiled: May 21, 2019Date of Patent: September 20, 2022Assignee: QUALCOMM IncorporatedInventors: Francis Ngai, Insung Kang, Reza Shahidi

Patent number: 11451949Abstract: Sidelink protocols enable user devices to rapidly find, make contact with, and continue communicating with other user devices. For example, vehicles in traffic can communicate on a low-complexity sidelink channel to cooperatively avoid collisions, saving countless lives. Disclosed protocols also enable mobile and IoT devices to form a self-organized temporary local network, independently of base stations. Example messages include a sidelink hailing message configured to discover other user devices, sidelink reply messages indicating the location or identity of each user device, sidelink semaphore messages indicating when each member enters and exits the temporary local network, and extremely fast low-latency emergency communication between vehicles. The disclosed low-complexity protocols may enable cost-constrained use cases that would remain unfeasible under 5G and 6G requirements, absent the systems and methods disclosed herein.Type: GrantFiled: January 28, 2022Date of Patent: September 20, 2022Assignee: ULTRALOGIC 6G, LLCInventors: David E.
