First Claim
Patent Images
1. A system, comprising:
- a vibration sensor that detects vibrations from a transport vehicle;
a motion detector configured to receive first input values based on first readings of the vibration sensor, to compare the received first input values to a first threshold value, and to determine that the transport vehicle is in a first operating state when one or more received first input values are above the first threshold value and to determine that the transport vehicle is in a second operating state when one or more received first input values are below the first threshold value; and
an adaptive threshold adjuster configured to identify a second threshold value as a replacement for the first threshold value,wherein the motion detector is further configured to compare received second input values based on second readings of the vibration sensor to the second threshold value and to determine that the transport vehicle is in the first operating state when one or more received second input values are above the second threshold value and to determine that the transport vehicle is in the second operating state when one or more received second input values are below the second threshold value.

12. A method, comprising:
-
generating, by a vibration sensor, first vibration values based on first vibrations of a transport vehicle; comparing, by a detection component, the first vibration values to a first threshold value and determining that the transport vehicle is in a first operating state when one or more of the first vibration values are above the first threshold value and determining that the transport vehicle is in a second operating state when one or more of the first vibration values are below the first threshold value; identifying, by an adaptive threshold component, a second threshold value as a replacement for the first threshold value; generating, by the vibration sensor, second vibration values based on second vibrations of the transport vehicle; and comparing, by the detection component, the second vibration values to the second threshold value and determining that the transport vehicle is in the first operating state when one or more of the second vibration values are above the second threshold value and determining that the transport vehicle is in the second operating state when one or more of the second vibration values are below the second threshold value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
