Abstract: Eliminate or reduce the impact of glare in printed information tag recognition applications using single- and multi-pose external illumination coupled with intelligent processing. A shelf imager can acquire shelf images for printed information tag localization and recognition. An external illuminator can provide at least one illumination condition/pose for shelf image acquisition in addition to lighting associated with the enclosed environment. A glare region of interest (ROI) detector can analyze all or a portion of the acquired shelf images for glare to determine whether additional images need to be acquired using different illumination conditions provided by the single- or multi-pose external illuminator or whether full or portion of acquired images need to be analyzed by a printed information tag locator and recognizer. A printed information tag locator and recognizer can analyze all or a portion of the acquired images to localize and recognize data printed on the printed information tags.

Abstract: Methods and systems for preventing collisions between vehicles and moving hazards include the use of active signs, a network of sensors, and a controller. Such sensors can be placed adjacent to a roadway and are used to detect the presence of animals. The active signs display a local speed limit. The controller accepts the sensor signals as input and outputs display commands to the active signs. The controller maintains a rolling window of recent detections in histogram form. The recent data, together with a control law specified by the municipal authority, can be used to specify updated local speed limits to influence driver behavior.

Abstract: The present invention generally relates to techniques for traffic monitoring. The techniques utilize a relatively low cost sensing system, referred to here as “smart tape.” Smart tape is adhered directly to the roadway and provides the ability to temporarily monitor traffic. It can be applied in an appropriate length for the roadway condition. Smart tape is responsive to the pressure of a vehicle's tires passing over it. Furthermore, smart tape does not require an attached monitoring device, unlike certain known traffic monitoring techniques.

Abstract: An articulating sheet guide is used in connection with a printing system. A primary media transport nip is disposed adjacent a media sheet source supplying a media sheet. A secondary media transport nip is downstream. A link has a front surface facing upstream, and a proximal end pivotally mounted. From adjacent the primary media transport, the link will pivot past the secondary media transport. A link pocket is disposed transversely to the process direction on the link front surface. The V-shaped link pocket is adapted to receive the media leading edge. The primary media transport nip will move the media sheet toward the link. The link pocket will receive the media leading edge. The media sheet movement will cause the link to move in an arcuate path guided by the pivotal movement of the link into engagement by the secondary media transport nip. The link pocket will release the media leading edge. The operation is nearly silent.

Abstract: A sensing method and system to protect printer print heads from substrate media contact comprising a trip wire sensor to detect and signal a printer control system that substrate media carried by transport media is positioned to strike or contact the print head. The trip wire sensor is located upstream of the print heads, a controlled distance above the transport media in the direction normal to the plane of the media, and comprises a trip wire operatively connected to at least one transducer. Substrate media exceeding the height requirements associated with the print heads contact the trip wire sensor causing the generation of an electrical signal which is received by the printer control system which then takes corrective action to prevent damage to the print heads, for example, by raising the print heads further away from the transport media and allowing the non-conforming substrate media to pass through and be purged. Also disclosed is a protective guide positioned to constrain substrate media from going over the top of the trip wire which can result in the substrate media becoming jammed in the trip wire sensor.
