The flexible sensor may have an electrical resistance that varies based on a radius of curvature of the flexible sensor, wherein the radius of curvature of the flexible sensor may be associated with a deflection of a spring providing a force to engage the carbon brush with a rotating component of the electrical machine. The signal processing circuit may be coupled to the sensor and may be configured to determine a measure of a wear state of the carbon brush using information about the variable resistance of the flexible sensor.

  • Patent number: 9556649
    Abstract: A key identification system that includes a key identification system housing, a key clamp, a key ring support tray, and two digital identifiers is disclosed. The key identification system housing may include a key receiving aperture extending through housing and sized to receive at least some of a key blade of a key. The key clamp is positioned adjacent to the key receiving aperture and allows the system to maintain the key blade in a fixed position within the key identification system housing when the key is inserted into the key receiving aperture. The key ring support tray is typically coupled to the key identification system housing below the key receiving aperture. The two digital identifiers are positioned within the key identification system housing and designed to capture key blade information.

  • Patent number: 9555429
    Abstract: A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.
