The invention discloses a dynamic automatic drive lane-changing trajectory planning method based on real-time environment information. A rollover limitation trajectory vertical coordinate, an optimal trajectory and a collision avoidance trajectory terminus security area are calculated; the relation between the rollover limitation trajectory vertical coordinate and the security area is compared, the positional relation between the optimal trajectory vertical coordinate and the security area is further compared, and then lane-changing decision-making is conducted. According to the dynamic automatic drive lane-changing trajectory planning method based on the real-time environment information, and a polynomial trajectory equation which dose not depend on time is adopted to represent a lane-changing trajectory curve, so that the problem that hypotheses of a speed and an accelerated speed are too strong is avoided; furthermore, collision avoidance algorithm and rollover prevention algorithm which are based on reaction time are introduced to guarantee security of lane-changing; then the optimal trajectory in a safe trajectory cluster is determined through real-time speed adjusting; and finally, an optimal lane-changing trajectory of real-time dynamic state is output through a trajectory generation module to guide an autonomous vehicle to complete a lane-changing behavior, and therefore a set of complete dynamic autonomous vehicle lane-changing trajectory planning module is built.

Embodments of the invention relate to a prosthetic, orthotic, or robotic foot having at least two joints. One joint is located in a position analogous to the human MTP joint, and the other is located in a position analogous to the human subtalar joint. Motions of these two joints are mechanically couples. Furthermore, these joints are created using “tensegrity” design principals, where connections between the compression members are made by a network of tension members. These tension members create axes of motion, and limitations on those axes of motion. Actuators or linear elastic “springs” are use to alter the torque / angular deflection response curve of these joints, so that the rollover profile of the human foot can be duplicated by this invention.

An embodiment of this invention pertains to a network processor that processes incoming information element segments at very high data rates due, in part, to the fact that the processor is deterministic (i.e., the time to complete a process is known) and that it employs a pipelined “multiple instruction single date” (“MISD”) architecture. This MISD architecture is triggered by the arrival of the incoming information element segment. Each process is provided dedicated registers thus eliminating context switches. The pipeline, the instructions fetched, and the incoming information element segment are very long in length. The network processor includes a MISD processor that performs policy control functions such as network traffic policing, buffer allocation and management, protocol modification, timer rollover recovery, an aging mechanism to discard idle flows, and segmentation and reassembly of incoming information elements.

The present foot prosthesis includes various structural features that provide the foot with advantageous rollover properties. In certain embodiments, the foot guides rollover toward the medial side. For example, an asymmetrical upper element and a correspondingly shaped resilient ankle member support more of the wearer's weight on the lateral side as the foot rolls over. In another embodiment, stiffeners added to the resilient ankle member increase the stiffness on the lateral side relative to the medial side. In certain other embodiments, the foot provides progressively increasing support from mid stance through toe off. For example, a gap between the resilient ankle member and the lower element closes during the later portion of the wearer's gait. The closing gap increases a contact area between the resilient ankle member and the lower element, providing progressively increasing support. In another embodiment, the foot includes a gap between a lower front edge of an attachment adapter and the upper element. The gap may be filled with a resilient material.

An on-chip clock multiplier for outputting a fast clock that is approximately a predetermined multiple n of a slow clock. The multiplier utilizing a high-speed oscillator to generate a high-frequency base signal. A lower frequency signal is generated using the high-frequency base signal as a function of the output of a rollover counter that counts from a seed value to a terminal value. A saturation counter is used to determine whether no more than n pulses of the lower frequency signal occur within a single cycle of the slow clock. If not, the lower frequency signal is iteratively slowed by changing the seed value until no more than n pulses of the lower frequency signal occur within a single cycle of the slow clock. When this iteration is done, the fast clock having a frequency that is approximately n times the frequency of the slow clock is output.
