    摘要： Exemplary methods include includes providing a film comprising at least one polymeric material; widening the film under a first set of processing conditions in a first draw step along the crossweb direction such that in-plane birefringence, if any, created in the film is low; and drawing the film in a second draw step along a downweb direction under a second set of processing conditions, wherein the second set of processing conditions creates in-plane birefringence in at least one polymeric material. Exemplary roll of film includes an oriented optical film characterized by an effective orientation axis. The oriented optical film comprises only one birefringent polymeric material, at least one birefringent material and at least one isotropic material, or a first birefringent material and a second birefringent material, the birefringent materials characterized by effective orientation axes along the MD. The optical film has a width of greater than 0.3 m and a length a length greater than 10 m.

    摘要： Described herein are systems, methods, and kits useful in stabilizing markers, such as driveway markers or garden stakes, that are placed in the ground. The invention comprises a marker stabilizer that can be inserted into the ground and that can receive a marker within an interior channel. The invention also comprises a cap that can be used to protect the marker stabilizer and a marker stabilizer remover that can be used to pull the marker stabilizer out of the ground.

    摘要： A visual display for use by a user for navigation and obstacle avoidance. A typical user employs the invention in operating a vehicle. The user may be located in the vehicle but will more typically be remotely located. The display may include a conventional video feed. A visual arch metaphor is also provided. If used in conjunction with a video feed, the arch metaphor preferably extends from the left side of the video, over the top of the video, and on to the right side of the video. A ranging device mounted on the vehicle collects ranging data around the vehicle. As an example, the ranging device might collect 180 degrees of ranging data extending from the vehicle's left side, across the vehicle's front, and over to the vehicle's right side. The ranging data is then correlated to a predefined color scale. The ranging data is also correlated to a position on the arch metaphor.
