Abstract
A vehicle traffic detecting device is provided with an automatic cleaning device. The detecting device has an emitter and a receiver facing each other and respectively emitting and receiving a beam of electromagnetic radiation along opposite ends of a beam path. The cleaning device has first and second cleaning units for respectively cleaning the emitter and the receiver. Each cleaning unit includes a fastener fastening the cleaning unit to a casing of the detecting device, a dispenser dispensing a transparent film, a contoured guide defining a film path along which the dispensed film resides, and an actuator for moving the dispensed film along the defined film path. A portion of the defined film path is located in front of the emitter/receiver of the detecting device and thereby positions a portion of the dispensed film in front of the emitter/receiver of the detecting device. The cleaning device also has a controller for automatically activating the actuators of the cleaning units in response to a predetermined signal from the detecting device signifying that at least one of the portions of the dispensed films currently in front of the emitter and receiver of the detecting device is fouled. The actuators when actuated move each of the dispensed films a distance along the film path such that the fouled portion(s) are moved beyond the front of the emitter/receiver and the portion of the dispensed film newly in front of the emitter/receiver is clean.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
