Abstract: Tracking of health and resilience of physical equipment and related systems are disclosed. A system includes physical equipment and one or more processors. The physical equipment includes one or more assets. The one or more processors are configured to determine a resilience metric for the physical equipment. The resilience metric includes a real power component and a reactive power component based, at least in part, on an aggregation of real components and reactive components of adaptive capacities of the one or more assets. A cyber-physical system includes physical equipment, network equipment configured to enable the physical equipment to communicate over one or more networks, a physical anomaly detection system (ADS) configured to detect anomalies in operation of the physical equipment and provide a physical component of a cyber-physical metric, and a cyber ADS configured to detect anomalies in network communications over the one or more networks.

Abstract: Disclosed herein are systems and methods for anomaly detection. A distributed physical state estimation system determines low-level state estimates covering respective sections of a cyber-physical system based on raw, high-performance measurement data. Low-level state estimates may be determined for a plurality of sections (substations) concurrently. An upper-level state estimate may be derived from the low-level state estimates. Anomalies pertaining to the system may be detected through analysis of the low-level and upper-level state estimates. The anomalies may be analyzed to determined whether the system is exhibiting behavior indicative of a fault, cyber-attack, and/or compromise.

Abstract: A docking station for storing a handset. A storage tray has a first recessed area for storing the handset and a second recessed area for a passenger to grip a top surface of the stored handset. The docking station includes a second latch extended into the second recessed area to engage an indent in the bottom surface of the handset. The docking station includes a first latch extended into the second recessed area to engage an indent located in the front surface of the handset. Depression of a release actuator retracts the first latch to release the top surface of the handset. The release actuator extends through an opening in the first recessed area, which has a length sufficient to allow a finger to actuate the release actuator and grip the top surface of the remote control handset while the remote control handset is stored in the storage tray.

Abstract: A data storage device may include one or more disks; a voice coil motor (VCM) driver for driving a VCM and having a programmable transconductance (Gm); an actuator arm assembly comprising one or more disk heads and the VCM, wherein the VCM is configured to operate in a first mode and a second mode; and one or more processing devices configured to control the actuator arm assembly to actuate the disk heads over corresponding disk surfaces of the disks, and further configured to: determine a current mode of operation of the VCM, the current mode of operation comprising the first mode; and transition the VCM from the current mode of operation to a new mode of operation, the new mode of operation comprising the second mode, wherein the transitioning comprises tuning the Gm from a first transconductance value to a second, different transconductance value.

Abstract: A data storage device comprises a disk; a head configured to read data from and write data to the disk; and a current balancer configured to receive a first voltage supply having a load limit and to receive a second voltage supply. The current balancer is further configured, to mitigate rotational vibration (RV) noise, to sample a first current IH5V drawn from the first voltage supply, to maintain a difference between the first current IH5V and a current balancer threshold parameter IThreshold to be at least twice a minimum peak current minCurrentLimitpk amount required for turn on of the current balancer (IH5V?IThreshold?2*minCurrentLimitpk), and to draw a second current from the second voltage supply to satisfy a part of a total load on the first voltage supply that exceeds the load limit.

Abstract: A data storage device comprises a lead actuator that actuates a first read-write head over a first disk and a support actuator that actuates a second read-write head over a second disk. A spindle motor rotates the first and second disks. In response to an emergency power off (EPO) event, a processing device retracts and parks the actuators using an internal supply voltage generated from a back electromotive force (BEMF) voltage of the spindle motor, and brakes the spindle motor. The spindle motor is not braked until both the lead and support actuators have been retracted and parked.

Abstract: A lubricant seal includes a sensor that utilizes the principles of diffraction gratings. The sensor is molded into the rubber structure of the lubricant seal and is disposed above the main sealing lip of the lubricant seal. The sensor may have a single or multiple diffraction gratings. The sensor measures wear of the lubricant seal, misalignment of the lubricant seal relative to a rotating shaft, or both. The sensor can be used for real-time monitoring and predictive maintenance.
