At least one of a selected animation an image and a character are displayed by vertical oscillation of a hand at a horizontal position of a light display device. In the horizontal position of the hand and also in the horizontal position of the light display device, a slider animation (directional arrow) is displayed without oscillation. When the light display device is upright, the device illuminates a red warning light on both sides. An illuminating device is switched on to display at least one of text, animation and a character by means of horizontal oscillation. When the light display device is caught from the right hand to the left, the displayed text, animation or character is automatically rotated to a readable position. When the device is lowered to the vertical position, the display is automatically interrupted.

Provided is a method executed by a marking device that marks a first pedestrian crossing to be visually recognized by a pedestrian who is going to cross a roadway and a second pedestrian crossing to be visually recognized by a driver of a vehicle on the roadway. The method includes: marking the first pedestrian crossing and the second pedestrian crossing when one or more conditions including at least a condition that a first pedestrian who is going to cross the roadway from a first side to a second side is detected are satisfied; starting to unmark the first pedestrian crossing from the first side to the second side while the first pedestrian is crossing the roadway; and unmarking the second pedestrian crossing when the first pedestrian has finished crossing the roadway.

A time-segmented signal timing method is related to the field of intelligent transportation. The specific implementation is: obtaining traffic volume data of a target intersection in each period of time of N consecutive days, N being an integer greater than 1; performing curve fitting on the traffic volume data to determine a traffic volume curve corresponding to the target intersection of each day; determining calculating respective target points in the traffic volume curve with second derivatives satisfying a preset condition; and performing time-segmented signal timing on a traffic light at the target intersection based on time points corresponding to the respective target points.

A positioning method includes: obtaining traffic control information indicative of transmission of a traffic control indication granting permission for vehicle motion, or permission for pedestrian motion, or a combination thereof and determining, based on the traffic control information, position-related information including a location of a user equipment (UE), a heading of the UE, or a combination thereof.

This invention is in the field of electricity and electronics, it focuses on reducing the risk of traffic accidents in people with visual or other disabilities who try to cross a road when there is no power or there is no one to guide them. To solve this problem, this device is proposed to be used in public spaces and roads. Characterized by a solar panel (3), some lamps (1), a mast (2) and housing (4) with sensors infrared, CCD, time of flight sensors, and mechanical sensors that are connected to the processor and connected to one audio output elements that gives spoken messages of risk to pedestrians, with energy autonomy and disconnected from the electricity grid.

A vehicle treatment system includes a signalling device with at least one sensor and a signal generator. The sensor can continuously detect the position of the vehicle in a predetermined approach region in front of or in the vehicle treatment system. The signal generator can output a signal which changes continuously or discretely and corresponds to a continuously changing position of the vehicle. In this case, the signalling device has at least two lights arranged above one another. A corresponding method can be used for determining and displaying entry information.

Techniques are provided to enable quick previews of what a modified document would look like. In an implementation, a set of page images are stored. Each page image represents a page of a document, the page having been converted to a page image for a first version of the document to permit the document to be viewed in a viewer program. A command is received to modify the document. The requested modification may include, for example, reordering pages, deleting pages, or extracting pages. A preview is generated for a second version of the document. The preview reflects the modification and uses at least one page image from the set of page images created for the first version of the document. Reusing page images allows the preview to be generated very quickly.

Systems, devices, and methods are disclosed in which one or more light sources, a detector, a processor and a controller are configured such that light from the one or more light sources improves the ability of a human or automated motor vehicle driver to identify and avoid pedestrians. The one or more light sources may provide spot illumination to moving objects or pedestrians on a road surface, with the spot illumination following the moving object or pedestrians along the portion of the road surface. The one or more light sources may project images on the ground or on other surfaces. The light source may be carried by a pedestrian or on personal transport used by a pedestrian. The light sources may be stationary and provide lighting for a pedestrian street crossing.
