Abstract: During a print cycle of a print apparatus, a liquid print agent including a carrier fluid is applied to a photoconductive surface. A proportion of the carrier fluid in the liquid print agent on the photoconductive surface is reduced at a first location by removably collecting a portion of the carrier fluid from the liquid print agent applied to the photoconductive surface. During a non-print cycle of the print apparatus, the removably collected portion of the carrier fluid is added to the photoconductive surface at the first location.

Abstract: Some embodiments of the present invention provide a method of navigating through a terrain using a human-scale vehicle, the method including: receiving an origin point and one or more destination points in the terrain; selecting route segments of a plurality of predefined route segments to navigate a user from the origin point to the one or more destination points in the terrain using the human-scale vehicle; obtaining motion data from one or more motion sensors disposed on at least one of the user and the human-scale vehicle during traveling of the human-scale vehicle along the selected route segments; and determining, based on at least a portion of the obtained motion data, terrain characteristics of the selected route segments.

Abstract: A database for mapping off-road terrain of various characteristics in three-dimensional terms, comprising: a plurality of road segment entries, each containing data pertaining to the terrain characteristics of the segment; and a plurality of elbow entries, each containing (x, y, z) coordinates of the elbow and a record for each road segment having the elbow as one of its end points, the record comprising navigation directives for vehicles entering the segment from the elbow.

Abstract: In an example, a method includes applying a liquid print agent comprising a carrier fluid to a photoconductive surface and reducing a proportion of the carrier fluid in the liquid print agent on the photoconductive surface at a first location during a print cycle of a print apparatus. The method may further include, during a non-print cycle of the print apparatus, adding carrier fluid to the photoconductive surface at the first location.

Abstract: Based on an origin location and a destination location, a navigation device is configured to provide an initial route. Traffic messages describing traffic events are received by the navigation device. Based on a location code in each of the traffic messages, the navigation device determines a traffic event delay if the location code corresponds to any remaining segment(s) of the initial route. If at least one of the traffic messages corresponds to any remaining segment(s) of the initial route, a travel delay is calculated based on one or more traffic event delays. The navigation device calculates a new route from the current location to the destination location, and, if a new travel time of the new route is less than a remaining travel time of the initial route from the current location to the destination location plus the travel delay, the navigation device outputs the new route.

Abstract: A Global Positioning System (GPS) enabled mobile device includes traffic map generation capability. The mobile device receives traffic messages including information about a traffic event. Based on the information included in the traffic messages and a current location, the mobile device generates a traffic map depicting a location of the traffic event and the current location.
