Abstract: Disclosed are embodiments of a vehicle-to-vehicle traffic queue information communication system, a traffic queue information communication device, and method. The system and method embodiments incorporate the use of multiple vehicles. Each vehicle is equipped with a traffic queue information communication device. Each traffic queue information communication device can be used to determine if its corresponding vehicle has entered or exited a queue in a single lane of traffic. When the vehicle is in a queue, the device can communicate with the immediately adjacent vehicles in front and behind. Specifically, it can receive data from the preceding vehicle in the queue and use the received data to determine its position in the queue as well as the estimated time it will take to travel through the queue. Revised data can then be transmitted by the device to the next vehicle in the queue for making the same determinations.

Abstract: The present disclosure is a method for alerting road users to the presence of an emergency vehicle. The method for alerting road user to the presence of an emergency vehicle may include receiving a short range signal, the signal including information regarding an emergency vehicle, decoding the signal, notifying a user, and transmitting the information regarding an emergency vehicle via a short range wireless signal. Each vehicle may include a short range wireless signal transceiver which could create a daisy chain distribution mechanism to distribute the information regarding an emergency vehicle to a first vehicle than to a second vehicle quickly and efficiently.

Abstract: A microwave oscillator comprises a semiconductor oscillating element, e.g. a Gunn diode (3) mounted at least partially within a dielectric substrate (1). The oscillating element is arranged, in use, to generate power at a predetermined fundamental frequency and at an harmonic frequency. The oscillator further comprises a circuit pattern (4) on the substrate arranged to transmit the power generated at the harmonic frequency to an output (10) whilst holding transmission of the power at the fundamental frequency.
