Abstract: A drill bit has a plurality of cutters secured to the bit body, including a gauge cutter defining a gauge diameter of the drill bit. A reciprocating gauge assembly on the bit comprises a cavity defined in the bit body, a piston reciprocably disposed in the cavity, a wear element on an outwardly facing end of the piston, a piston retainer for moveably retaining the piston in the cavity, and a spring biasing the piston outwardly to a neutral position of the wear element with respect to the gauge diameter. The wear element and piston may be urged inwardly in response to an applied load at the drill bit gauge pad, increasing the lateral depth of cut and thereby controlling the aggressiveness of the bit in response to the load.

Abstract: A system for trajectory prediction with agent prioritization is provided. A motion encoder is configured to determine future directions of agents of a plurality of agents and strengths of the agents based past trajectory information. The past trajectory information includes past trajectories of the agents at a number of time steps over a given time horizon for the agents. An inter-agent encoder is configured to determine the relations between the agents based on the future directions and the strengths. The relations identify motion impacts between the agents. The inter-agent encoder is further configured to calculate a motion prioritization score for each agent of the plurality of agents based on the relations between the agents. The motion prioritization scores define a priority order. The motion decoder is configured to calculate sequential predictions for future trajectories of the agents based on the motion prioritization scores.

Abstract: Systems and methods for uncertainty estimation in vehicle trajectory prediction are provided. In one embodiment, a method includes calculating predicted error scores for each static data point of a set of static data points for a new traffic scenario. A static data point corresponds to a location of the new traffic scenario. The method includes ranking the static data points of the set of static data points based on the predicted error scores. The method further includes selecting a predetermined percentage of the ranked static data points having the highest predicted error scores of the ranked static data points. The method includes identifying locations of the new traffic scenario corresponding to the selected ranked static data points. The method includes collecting additional data points from the identified locations of the new traffic scenario. The method includes training a decoder for a neural network based on the additional data points.

Abstract: The present invention is directed to an apparatus and method for performing ultrasound optical imaging with respect to a sample in which an acoustic field is generated in response to a stimulus. The apparatus comprises a sensor head having an acoustically sensitive surface arranged as a reflective surface of a Fabry Perot interferometric cavity, wherein, when the acoustically sensitive surface is placed against the sample, in use, the acoustic field generated in response to said stimulus is incident upon said acoustically sensitive surface to modulate the optical path length in the cavity with a signal indicative of the acoustic field. Interrogation of the sensor head is performed based on regions having common bias phase.

Abstract: A method and apparatus for running a whipstock into a well bore attached to a combination mill and drill bit, releasing the mill/bit from the whipstock, milling a window in the casing, and drilling a lateral well bore, all in one trip. The mill/bit is provided with a primary cutting structure better suited for milling through the casing, and a secondary cutting structure, better suited for drilling through the earth formation. The secondary cutting structure is initially smaller in diameter than the primary cutting structure. The whipstock can be attached to the mill/bit with a shear bolt supported by a boss on the whipstock, with the boss designed to arrest axial motion of the mill/bit after shearing of the bolt.
