Abstract: A computer-implemented method for safeguarding a system against false negatives. The method includes: receiving a time series of a criticality, the system including a functionality that is triggered when the criticality meets a first predetermined criterion; computing a time series of a reference, the reference being a comparison criticality for triggering the functionality; computing a time series of an error measure based on the time series of the criticality and the time series of the reference, a non-triggering of the functionality being classified as a false negative when a portion of the time series of the error measure meets a second predetermined criterion; and identifying at least one near-false negative, a non-triggering of the functionality of the system being classified as a near-false negative when a portion of the time series of the error measure meets a third predetermined criterion, but not the second predetermined criterion.

Abstract: A computer-implemented method for safeguarding a system against false positives. The method includes: receiving a time series of a criticality, the system including a functionality that is triggered when the criticality meets a first predetermined criterion; computing a time series of a reference, the reference being a comparison criticality for a triggering of the functionality; computing a time series of an error measure at least based on the time series of the criticality and the time series of the reference, a triggering of the functionality being classified as a false positive when a portion of the time series of the error measure meets a second predetermined criterion; and identifying at least one near-false positive, a non-triggering of the functionality being classified as a near-false positive when a portion of the time series of the error measure meets a third predetermined criterion, but not the second predetermined criterion.

Abstract: Sweep retaining structure includes a retainer having a contact end biased towards the sweep. The sweep includes two or more spaced end-receiving areas to accommodate changes in the mounted sweep position. In one embodiment, the retainer is a wire made of spring steel having a contact end biased against the underside of the sweep. In one embodiment, the underside of the sweep includes a series of stepped portions. As the sweep is forced on the adapter on the shank, the contact end springs into retaining position on the stepped portion that aligns with the spring end when the sweep is in the mounted position. The sweep can be attached loosely by hand in an initial position with operating forces moving the sweep to a wedge locked position.
