    Abstract: Disclosed are techniques for traffic flow control. In an aspect, an on-board computer (OBC) of a vehicle of a secondary traffic flow determines that a primary traffic flow is passing through an intersection associated with a traffic light, wherein the determination that the primary traffic flow is passing through the intersection is based on sensor data from one or more sensors of the vehicle, vehicle-to-vehicle (V2V) communication, vehicle-to-everything (V2X) communication, or any combination thereof, and reduces a speed of the vehicle to prevent the vehicle from tripping a traffic light sensor associated with the traffic light until after the primary traffic flow has passed through the intersection.

    Abstract: System and method for adjusting timing error in a mobile device. In the mobile device, a crystal oscillator (XO) is used by a system timer as the timing source. When the mobile device enters into a sleep mode, the system timer is set to time the duration of the sleep mode. During the sleep mode, a thermistor is used to measure and monitor the temperature changes of the XO. After the sleep mode is over, a processor in the mobile device determines the frequency changes of the XO based on the temperature changes of the XO. Based on the frequency changes of the XO, the processor determines the timing error that may have occurred when the system timer was timing the sleep mode and determines the actual duration of the sleep mode by adjusting the duration timed by the system timer based on the timing error.
