Abstract: A telescopic, height adjustable, bicycle seatpost with a fixed frame insertion length, but adjustable uncompressed resting height is described herein. This telescopic bicycle seatpost with adjustable height and fixed frame insertion provides a unique structure and method for setting the uncompressed resting height of a telescopic bicycle seatpost, while using a fixed insertion length into the bicycle frame. The assembly allows a single telescopic bicycle seatpost to fit on many different sizes of bicycle, for cyclists of varied height and leg length, while maximizing the telescoping length of the seatpost for each situation, without requiring various lengths of seatpost to be manufactured. Instead, the telescoping length of the seatpost may be adjusted for cyclists of different height, allowing for one seatpost to fit many size frames and cyclists, while allowing each individual to maximize the telescoping length for their particular setup.

Abstract: Disclosed herein are system, method, and computer program product aspects for validating protolanes. For example, the method includes determining a protolane level flowchart from one or more flowcharts corresponding to one or more gates of a protolane selected from a set of protolanes of a geonet, wherein the one or more flowcharts correspond to conditions that can be encountered by an actor approaching the corresponding one or more gates, and wherein the geonet comprises a plurality of lane segments associated with the set of protolanes. A graph through the protolane level flowchart is generated that corresponds to actions of an actor. Reasoning of the actor is validated by testing the actions of the actor against the graph through the protolane level flowchart.
