Publication number: 20210191496Abstract: A method and a gateway system for enabling adaptive power management. The gateway system is powered by a rechargeable battery that is coupled with a solar power source. A location reading indicating a location of the gateway system is transmitted at a first time. A solar profile is received from a management server. The solar profile indicates a measure of power expected to be generated at the location during an interval of time that occurs after the first time by the solar power source. The gateway system determines based on a current battery level of the rechargeable battery and the solar profile an optimal power usage plan for the gateway system and operates according to the optimal power usage plan during the interval of time.Type: ApplicationFiled: March 5, 2021Publication date: June 24, 2021Inventors: Brian TUAN, Kavya U.

Publication number: 20210103719Abstract: Methods for improving compliance with regulations pertaining to vehicle driving records are disclosed. One or more digital images from a camera mounted in a vehicle are received. Based on a determination that the vehicle has hours of service that have not been assigned to a driver, a subset of the one or more digital images corresponding to the hours of service are identified based on the timestamps. The subset of the one or more digital images are processed to identify a correspondence between a face of a person included in the one or more digital images and a face of a known person. Based on the correspondence transgressing a threshold level of correspondence, a user interface is generated for presentation on a device. The user interface includes an interactive user interface element for accepting a recommendation to assign the known person as the driver for the unassigned hours of service.Type: ApplicationFiled: July 15, 2020Publication date: April 8, 2021Inventors: Evaline Shin-Tin Tsai, Alan Guihong Liu, Ijeoma Emeagwali, Ishaan Kansal, Saleh ElHattab, Bodecker John DellaMaria, Eliott Ray Chapuis, Jason Noah Laska, Jennifer Kao, Sean Kyungmok Bae, Sylvie Lee, Brian Tuan

Publication number: 20210104159Abstract: Methods for performing operations for improving driver safety across a fleet of vehicles are disclosed. A plurality of safety events pertaining to a driving of a fleet of vehicles by a plurality of drivers are detected. A subset of the events is identified. The subset corresponds to one or more safety events of the plurality of safety events involving one or more vehicles of the fleet of vehicles to which drivers have not been assigned. A user interface is generated for presentation on a client device, the user interface including an interactive user interface element for accessing the subset of the events. One or more user interface elements are provided for accepting or rejecting recommendations for assignments of one of the plurality of drivers to each of the vehicles. The recommendations are generated based on an application of a machine-learned model to images of faces captured.Type: ApplicationFiled: July 15, 2020Publication date: April 8, 2021Inventors: Evaline Shin-Tin Tsai, Alan Guihong Liu, Ijeoma Emeagwali, Ishaan Kansal, Saleh EIHattab, Bodecker John DellaMaria, Eliott Ray Chapuis, Jason Noah Laska, Jennifer Kao, Sean Kyungmok Bae, Sylvie Lee, Brian Tuan
