Abstract:
1. A method of determining vibrational frequencies in a device having a first sensor in connection with a first component and a second sensor in connection with a second component, said method comprising: receiving a first input from the first sensor in connection with the first component of the device, said first sensor being configured to detect movement of the first component; receiving a second input from the second sensor in connection with the second component of the device, said second sensor being configured to detect movement of the second component; determining the frequency of vibration of the first component using the first input received from the first sensor and the frequency of the second component using the second input received from the second sensor; comparing the frequency of vibration of the first component to the frequency of vibration of the second component; and determining whether the frequency of vibration of the first component is substantially synchronized with the frequency of vibration of the second component.
