A turbine exhaust thin strut includes an airfoil section having a profile substantially in accordance with at least an intermediate portion of the Cartesian coordinate values of X, Y and Z set forth in Table 2. The X and Y values are distances, which when smoothly connected by an appropriate continuing curve, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form a complete airfoil shape.

A method for detecting critical driving situations of motor vehicles, in particular for preventing collisions with an object in front of an own vehicle, has the following steps: detection of a current vehicle acceleration and a current vehicle velocity of an own vehicle; specification of an acceleration profile depending on driving variables of the own vehicle; assumption of a time progression of a foreseeable acceleration of the own vehicle based on its current acceleration; determination of a path profile of the own vehicle from the time progression of the foreseeable acceleration; acquisition of a current distance and a current relative velocity of an object in front of the own vehicle; calculation of the current absolute velocity of the object as well as of the absolute current acceleration of the object; assumption of a time progression of a foreseeable acceleration of the object based on its current acceleration; determination of a path profile of the object from the time progression of the foreseeable acceleration; comparison of the path profile of the own vehicle with the path profile of the object; and if the two path profiles intersect, determination of a probable collision time of the own vehicle with the object; establishment of a time before the probable collision time comparison of this time with the probable collision time determined; and if the probable collision time lies before the established time, issue of a warning to the driver of the own vehicle.

A tensioner for imparting tension to a chain having a body, a resilient chain guide element, at least one blade spring, and at least one bracket. The body of the tensioner has a surface with a profile of the path of a new chain and a groove found longitudinally along the length of the surface. The resilient chain guide element, on the surface of the body has a chain contact surface and two ends wrapped around the ends of the body, with the chain guide being sufficiently larger than the body, such that the chain contact surface is capable of being biased away from the body. The blade spring is present in the groove with its end in the containments means of the groove, biasing the chain guide out and away from the body.

A system and method for using a gantry crane to efficiently and safely transport loads such as containers and ship hatch covers from one location to another along a known path while avoiding collisions between the loads and obstructing objects which may be situated in the known path. A transceiver emitting laser beams may be used to establish both the position of the spreader and its load and the profile of the known path. Continuous comparisons are made by computer between the location of a dynamic digital protective envelope constructed around the crane spreader and its load, if any, and a digital representation of the profile of the known path to be traveled by the spreader and its load, if any. In the event, the comparison indicates intersection of the protective envelope and the path profile, a speed limit is imposed on the motor controlling the movement in the X axis of the trolley or in the Z axis of the spreader, as required to prevent a collision.

A data structure for implementing a traffic engineering function in a multiprotocol label switching system comprises: a subscriber profile including a plurality of entries for storing forwarding equivalence class (FEC) information, the entries of the subscriber profile being sequentially assigned indexes corresponding to one traffic engineering service subscriber identification (ID); a path profile including a plurality of entries for storing respective path information items regarding a type length value (TLV) of a signal protocol, the entries of the path profile being sequentially assigned indexes corresponding to respective path information items; and a quality of service (QoS) profile including a plurality of entries for storing respective QoS information items regarding a TLV of a signal protocol, the entries of the QoS profile being sequentially assigned indexes corresponding to respective QoS information items. The indexes assigned to the profile entries include a plurality of indexes set by an operator for interlinking corresponding ones of the subscriber profile entries, the path profile entries, and the QoS profile entries.

This paper describes preferential path profiling, which enables profiling a specified subset of all possible program paths with very low overhead. Preferential path profiling compactly identifies paths of interest using an array. More specifically, PPP assigns a unique and compact path index identifier to all interesting paths that can be used to index into a path array. The path array contains a second path value identifier that is used to distinguish interesting paths from other program paths This path numbering allows the implementation of preferential path profiling to use array-based counters instead of hash table-based counters for identifying paths of interest and gathering path profiles, which significantly reduces execution time and computational resource overhead during profiling.

A technique for efficiently rendering path images tessellates path contours into triangle tans comprising a set of representative triangles. Topology of the set of representative triangles is then optimized for greater rasterization efficiency by applying a flip operator to selected triangle pairs within the set of representative triangles. The optimized triangle pairs are then rendered using a path rendering technique, such as stencil and cover.

According to some embodiments, the system calculates the first trajectory based on map and route information. The system generates a path profile based on the first trajectory, the traffic rules, and obstacle information describing the one or more obstacles perceived by the ADV, wherein, for each obstacle in the plurality of obstacles, the path profile includes yielding or Decision to skim to the left or right of the obstacle. The system generates a speed profile according to traffic rules based on the route profile. The system performs a gradient descent optimization based on the path profile and the velocity profile to generate a second trajectory representing the optimized first trajectory, and controls the ADV according to the second trajectory.

A system processes communication path requests in an autonomous system. The system includes a proxy server that receives a request message from an external system requesting establishment of a communication path through the autonomous system. The request message includes a desired communication path profile including a desired level of redundancy. The system also includes a management server in the autonomous system that receives the request message from the proxy server, generates a response message indicating whether a communication path corresponding to the desired communication path profile is available, and sends the response message to the proxy server. The proxy server receives the response message and transmits the response message to the external system.
