Abstract: A method is disclosed for determining vibrational anomalies of a vehicle. An object is removably attached to a wheel of the vehicle in a manner that inhibits the object from coming off of the vehicle when the vehicle is in operation. The object includes one or more inertial measurement units (IMU's) mounted to the object and configured to measure parameters that are used for calculating the vibrational anomalies when the vehicle is in operation. Motion data captured by the one or more IMU's is collected. The collected motion data is processed to determine the presence of one or more vibrational anomalies of the vehicle. A recommended corrective action to be taken is determined when the result of the processed data indicates the presence of one or more vibrational anomalies of the vehicle.

Abstract: A data storage control unit is coupled to one or more host devices and to one or more physical storage units, the storage control unit configured as a plurality of clusters. Each cluster includes cache memory and often non-volatile storage (NVS). The storage control unit receives and processes write requests from the host devices and directs that data updates be temporarily stored in the cache in one cluster and copied to the NVS of the other cluster. The data updates are subsequently destaged to the logical ranks associated with each cluster. During an initial microcode load (IML) of the storage controller, space in the cache and NVS of each cluster is allocated to buffers with the remaining cache and NVS space being allocated to customer data. After an IML has been completed, the size of the buffers become fixed and no further buffer allocation may occur.
