Patent number: 11995983Abstract: A method of detecting overspeeding for a vehicle, the method including obtaining historical trajectory data of a fleet of geographical areas from an electronic database; determining, by a microprocessor of a server, a distribution of speed of the historical trajectory data for each geographical area; based on the distribution of speed, determining, by a microprocessor of an electronic device associated with the vehicle, that a current speed of the vehicle is above a threshold speed corresponding to a pre-determined percentile of the distribution. A system and a computer-readable medium storing computer executable code for the method.Type: GrantFiled: September 15, 2021Date of Patent: May 28, 2024Assignee: GRABTAXI HOLDINGS PTE. LTD.Inventors: Muhammad Rameez Chatni, Munirul Abedin, Laiyi Lin, Miaojun Li

Patent number: 11879989Abstract: In an embodiment, an antenna subsystem includes a sparse receive antenna and an electronically steerable transmit antenna. The sparse receive antenna includes an array of electronically steerable receive elements each configured to receive a respective signal having a wavelength and each spaced apart from each adjacent one of the receive elements by a respective first distance that is more than one half of the wavelength. And the electronically steerable transmit antenna includes an array of transmit elements each configured to radiate a respective signal having the wavelength and each spaced apart from each adjacent one of the transmit elements by a respective second distance that is less than one half of the wavelength. To reduce aliasing, such an antenna subsystem can be operated to filter, spatially, a receive beam pattern generated by the receive antenna with a transmit beam pattern generated by the transmit antenna.Type: GrantFiled: June 16, 2020Date of Patent: January 23, 2024Assignee: Echodyne Corp.Inventors: Nicholas K. Brune, Muhammad Rameez Chatni, Tom Driscoll, Jonathan R. Hull, John Desmond Hunt, Christopher L. Lambrecht, Nathan Ingle Landy, Milton Perque, Charles A.

Patent number: 11823572Abstract: A method of detecting overspeeding for a vehicle, including obtaining historical trajectory data of a fleet, of geographical areas from an electronic database; determining, by a microprocessor of a server, a distribution of speed of the historical trajectory data; calculating, on an electronic device associated with the vehicle, a determined probability of future overspeeding; wherein obtaining includes communicating, by the server an electronic request to the electronic database for the historical trajectory data, and the historical trajectory data from the electronic database to the server. An electronic device including a trajectory data acquisition circuit; a communication circuit to receive pre-trained weights for a trained classifier from a server; a processor to use a classifier configured with the pre-trained weights to calculate, based on trajectory data, a probability of future overspeeding being higher than a pre-determined threshold.Type: GrantFiled: August 18, 2021Date of Patent: November 21, 2023Assignee: GRABTAXI HOLDINGS PTE.
