Abstract: The problems of hitching are typically focused on the alignment of the mating components. As a result, assist products tend to offer fragmented solutions and lack universal appeal in the marketplace. The Tru-Hitchin Model using Dual Beam Technology and Triangulation develops a Spatial Triangle with the aid of hardware, as a framework for positioning and alignment of any mating components. The Model transforms two dimensional vehicle movements into a 3rd dimensional beam movement for operator viewing. The operation requires a one-time initialization after which all future hitching is performed safely by one operator with ordinary parking skills. Alignment is complete when the dual functional laser beams are on selected pivot points.

Abstract: Under the present invention, a warning unit having a light source (e.g., a laser) is mounted on an emergency vehicle. The light source first emits a low intensity light beam (e.g., an infrared light beam) to scan an area in front of the emergency vehicle. The scan is used to detect one or more objects having a height to width ratio exceeding a predetermined threshold. Specifically, the scan is used to detect one or more tall, narrow objects such as poles, sign posts, etc., while ignoring other objects such as people, animals, etc. Once any applicable objects are detected, a second, higher intensity light beam is emitted to illuminate the detected objects with a predetermined indicia. The predetermined indicia can be observed by other motorists and indicates to them a direction of origin of the emergency vehicle.
