Radar tracking with model estimates augmented by radar detections
This document describes radar tracking with model estimates augmented by radar detections. An example tracker analyzes information derived using radar detections to enhance radar tracks having object measurements estimated from directly analyzing data cubes with a model (e.g., a machine-learning model). High-quality tracks with measurements to objects of importance can be quickly produced with the model. However, the model only estimates measurements for classes of objects its training or programming can recognize. To improve estimated measurements from the model, or even in some cases, to convey additional classes of objects, the tracker separately analyzes detections. Detections that consistently align to objects recognized by the model can update model-derived measurements conveyed initially in the tracks. Consistently observed detections that do not align to existing tracks may be used to establish new tracks for conveying more classes of objects than the model can recognize. |

Methods and systems for improving the operation of transmissions for motor vehicles
The hydraulic circuitry of a factory installed automatic automotive transmission is modified to replace an underdrive accumulator spring with a shorter spring and a separate lower rated spring washer operatively associated with the shorter replacement underdrive accumulator spring.

The spring washer has a lower spring rating than the replacement spring, so that less fluid pressure is required to move the piston the total distance traveled, resulting in less fluid pressure applied to an underdrive clutch than in the factory installed transmission. The spring ratings of the replacement spring and the spring washer are selected such that the total fluid pressure required to move the piston both the first and second predetermined distances is less than the fluid pressure required to overcome the resilient force of underdrive piston return springs acting on an underdrive apply piston so that a lower fluid pressure is applied to an underdrive clutch. |
