Patent number: 11423779Abstract: Exemplary embodiments described in this disclosure are generally directed to vehicle detection systems and methods. In one exemplary embodiment, a vehicle detection system that is provided in a first vehicle receives a map generated by a vehicle detection system of a second vehicle. The map, which can be a cardinal map, for example, indicates a third vehicle that is detected by the vehicle detection system of the second vehicle and is undetectable by the first vehicle due to various reasons. For example, the first vehicle may fail to detect the third vehicle due to signal blocking caused by an intervening vehicle located between the first vehicle and the third vehicle, or due to the loss of radio-frequency (RF) signal reception by the vehicle detection system in the first vehicle. The second vehicle can detect the third vehicle by using radio-frequency (RF) signals and to convey the information to the first vehicle.Type: GrantFiled: February 15, 2019Date of Patent: August 23, 2022Assignee: Ford Global Technologies, LLCInventors: Samer Ibrahim, Sushanta Das

Patent number: 10152685Abstract: Techniques described herein are directed towards dynamically adding new pickup orders to an existing route structure. In at least some embodiments, a service provider separates a number of vendors into separate clusters based on one or more attributes. For example, the vendors may be separated by geographic region. The service provider may then identify a set of routes that are associated with each of the vendor clusters and run optimization techniques on that set of routes. The set of routes may be filtered based on attributes of the route. In some embodiments, the service provider may make a route alteration that accommodates the new pickup order.Type: GrantFiled: January 3, 2017Date of Patent: December 11, 2018Assignee: Amazon Technologies, Inc.Inventors: Kalyanakrishnan Ananthanarayanan, Rajiv Kumar Poddar, Tej Paul Verma, Sushanta Das, Ankit Kumar Yadav, Eric Yuk-Hon Kan, Mark Robert Michener
