Least squares fit classifier for improved sensor performance
An improvement to sensor detection performance is described through use of novel least squares based (or other) sensor measurements fitting, which can significantly improve or increase the sensor Probability of Detection (Pd) while simultaneously improving or decreasing the sensor Probability of False Alarm (Pfa). Instead of just thresholding a scalar magnitude as is done in prior art signal detection methods, the new method seeks to classify time (or space, or spatio-temporal) sequenced Signal measurements from time (or space, or spatio-temporal) sequenced Noise measurements through unique features characteristic of each. The proposed method ma be implemented on most modern Radar Signal Data Processors (SDP) and therefore affords a near term, low cost opportunity to both significantly increase detection and tracking performance and/or enable ready adoption of new additional auxiliary missions currently not possible with resource constrained sensors. |

Managing conflicts using conflict islands
In some implementations, a computing device can manage conflicts using conflict islands. For example, when a computing device receives bulk map data updates, the computing device can determine conflicts between point updates (e.g., small, ad hoc feature edits) in the current map data and the bulk map data updates.

The computing device can determine a perimeter of stable map features around the conflicted feature. The map features within the perimeter can correspond to a conflict island. The bulk updates for features within a conflict island (e.g., within the perimeter) can be deferred until resolved while bulk updates for features outside of a conflict island can be applied to the current map data. |

Provided are systems and methods for cloaking an object on a ground plane.

Methods and systems are provided for an oxygen sensor heater. In one example, a method may include applying a less than maximum duty cycle of voltage to the oxygen sensor heater during an engine cold start (e.g., when a temperature of the oxygen sensor is less than its light-off temperature) and adjusting the applied duty cycle of voltage to maintain a constant amount of power.

Method for predicting knock, method for suppressing knock, and engine system
A method and system for predicting the occurrence of a knock which will have a predetermined intensity or higher (intense knock) in an engine that burns an air-fuel mixture of gasoline fuel. The pressure in a combustion chamber is detected during an initial stage of combustion. This pressure is compared with a preset reference value to determine whether or not the cylinder inner pressure exceeds the reference value during the combustion. When the cylinder inner pressure exceeds the reference value, it is predicted that the intense knock will occur before an end of the combustion. If the intense knock is predicted, additional fuel or other material can be injected into the combustion chamber to prevent the occurrence of the intense knock. |
