A method includes performing, with a compacting machine, a first pass to compact a first portion of a work area to compact a first lane. A guidance system acquires position information representing the first compacted lane. A second pass is performed to compact a second portion of the work area adjacent the first portion. The guidance system acquires current position information of the machine representing current positioning of the machine during the second pass. Comparing the position information of the machine representing the first compacted lane with the current position information, determines whether the current positioning overlaps the first compacted lane a specified amount. When the second pass is determined to overlap the first compacted lane, in-compliance visual indicia is generated. When the second pass is determined to not overlap the first compacted lane with the specified amount, out of compliance visual indicia is generated.

A bicycle handgrip device includes a first handgrip, a second handgrip, and a light. The first handgrip defines a first axis, with a first connection end and a second connection end disposed on two ends thereof. The first handgrip is mounted around the handlebar of a bicycle through the first connection end. The second handgrip is removably combined to the second connection end. The second handgrip defines a second axis perpendicular to the first axis and pointing at the ground surface. The light is disposed on the second handgrip for projecting light beam on the ground surface. Therefore, the light provides illumination and a warning light signal at different distances. Also, the handgrip device can be gripped in different directions, so that the user is allowed to adjust the gripping position for lowering habitual motion fatigue.

A vehicle may include a movable roof, a sensor supported by the roof, and an actuator for selectively raising and lowering the roof.

Improved passenger access and suspension systems for passenger buses, and controllers configured for use therewith; and passenger buses incorporating such systems and controllers. Integration of access ramp, door, suspension, charge interface, and other systems provides improvements in fully- or semi-automatic deployment of features such as passenger doors and ramps, and charge interface components, as well as navigation to passenger access points.

A vehicle may include: a camera configured to obtain a surrounding image of the vehicle; and a controller configured to derive spatial recognition data by learning the surrounding image of the vehicle as an input value, derive object recognition data including wheel area data of surrounding vehicles by learning the surrounding image of the vehicle as an input value, determine a ground clearance between a bottom surface of a vehicle body of the surrounding vehicle and a ground by use of the spatial recognition data and the wheel area data, and control the vehicle to park the vehicle by reflecting the ground clearance.

A safety lighting system for use with trailers is described herein. In some embodiments, the trailer lighting system comprises a sensor, a controller, and safety lights. The safety lighting system may be used for illuminating trailers while being towed, for example, in shipping yards, construction yards, and shipping and receiving docks. The safety lighting system may be activated upon connection of a pneumatic system with a spotting tractor and deactivated upon establishing an electrical connection from a tractor to the trailer.

A vehicular lighting system includes a light projecting device disposed at each headlight of a vehicle. The light projecting device is part of the respective headlight. The light projecting device, when operated, projects an animated sequence of visual images or a sequence of visual light patterns on a wall in front of the vehicle. The projected animated sequence of visual images or projected sequence of visual light patterns is viewable at the wall by a driver of the vehicle. The light projecting device may include a matrix of light emitting diodes. The visual images or visual light pattern projected by the light projecting device, when operated, may change as distance between the vehicle and the wall decreases.

A light assembly for attachment to a surface. The light assembly includes a base configured to be coupled to the surface and a light head coupled to the base and including a light source. The light head is movable relative to the base from a predetermined position. The light assembly further includes a motor coupled to the base and the light head to move the light head relative to the base and a remote configured to control movement of the light head with respect to the base. The remote including an actuator operable to return the light head to the predetermined position.
