US Patent:

20210357757, Nov 18, 2021

Filed:

May 15, 2020

Appl. No.:

16/875792

Inventors:

David T. Nguyen - Rockville MD, US

International Classification:

G06N 3/08
G06K 9/62

Abstract:

A system for customizing an artificial intelligence model to process a data set. The system includes an electronic processor that is configured to receive a data set, train a plurality of artificial intelligence models using the received data set, and determine, for each the plurality of artificial intelligence models, an accuracy. The electronic processor is further configured to receive a selection of an artificial intelligence model, receive one or more adjustments to one or more features or feature weights of the selected artificial intelligence model, and execute the selected artificial intelligence model with the one or more adjustments to categorize records in a data set different from the received data set.

David H Nguyen - Southbridge VA, US

International Classification:

G08G 1/08
G08G 1/01
G08G 1/052
G08G 1/056

Abstract:

A traffic detection device for sending a call signal to a traffic signal controller, the traffic detection device having a receiver to receive information sent from a mobile device, the information including identity information and/or location information of the mobile device, a traffic control device (TCD) interface to connect the traffic detection device to the traffic signal controller, and a processor to define a dynamic approach based on one or more of the identity information, speed limit, time of day, or speed of the mobile device. The device may determine whether to send a calf signal to the traffic signal controller via the TCD interface to prompt the traffic signal controller, when the processor determines that the mobile device is in the dynamic approach.

- Arlington VA, US
David Hong Nguyen - Southbridge VA, US

International Classification:

G08G 1/01
G08G 1/081

Abstract:

A system for adaptively controlling traffic control devices having a traffic signal system, a computing network, a communication system, and a mobile device. The traffic signal system is configured to be in communication with the computing network through the communication system. The mobile device is also configured to be in communication with the computing network through the communication system. Then the computing network adaptively controls the traffic signal system using a location of the mobile device.
