Abstract: A circuit includes a bandgap circuit configured to generate multiple reference voltages. A first voltage glitching detection circuit utilizes a first one of the reference voltages and a first power rail to generate a first reset signal in response to a voltage glitching attack on the first power rail, and a second voltage glitching detection circuit operates independently of the reference voltages to generate a second reset signal in response to the voltage glitching attack on the first power rail.

Abstract: A data storage device, such as a hard disk drive (HDD), includes a rotary actuator pivot bearing assembly configured with a bearing span less than the maximum available bearing span, thereby reducing the pivot tilt gain of a corresponding acoustic transfer function relative to a pivot tilt (PT) gain of an original acoustic transfer function corresponding to the maximum available bearing span. To counteract consequent reductions in the coil torsion and pivot tilt frequencies, the voice coil is vertically thickened to increase the coil torsion (CT) frequency and pivot tilt frequency closer to their values in the original acoustic transfer function. Combining a relatively short bearing span with a relatively thick voice coil maintains relatively high CT and PT frequencies while simultaneously ensuring relatively low PT gain, thereby improving the structural dynamics of the system and the NRRO associated with operational vibration.

Abstract: Methods, systems, and devices for data management are described. A data management system may determine risk levels for a plurality of computing objects. A risk level for a computing object is determined based on a respective quantity of elements comprising sensitive information within the computing object and a respective quantity of users with access to the computing object. The data management system may display the visualizations for a selected subset of computing objects in a user interface. The visualizations for the computing objects may be positioned within the user interface based on respective quantities of elements comprising sensitive information within the computing objects and further based on respective quantities of users with access to the computing objects. The user interface may be configured to receive a selection of a time period and reposition the visualizations of the computing objects within the user interface.

Abstract: An IC package includes a die and an elongate conductive trace formed adjacent to at least one peripheral edge of the die. Test logic in the package performs a die crack test by applying a test pattern to a first end of the conductive trace and sensing a response pattern at a second end of the conductive trace. The package is configured to operate in at least two distinct modes, including a manufacturing test mode in which a die crack test result is communicated from the package out of a JTAG port, and a field test mode in which the die crack test result is communicated from the package out of a data transfer port. A vehicle computer system may perform a fail safe action based on the die crack test result.

Abstract: Aspects of the present disclosure generally relate to apparatus and methods for an adjustable de-chucking voltage associated with an electrostatically charged substrate in a processing chamber. An example method of de-chucking a substrate disposed in a process chamber includes processing a substrate in a chamber body, the substrate being coupled to a substrate support comprising a chucking electrode. The method further includes monitoring a property associated with a lift pin assembly movable relative to the chucking electrode via an actuator. The method further includes adjusting a first voltage level applied to the chucking electrode in response to the property associated with the lift pin assembly satisfying one or more criteria.

Abstract: A hard disk drive includes multiple disk media mounted on a spindle, where the outer diameter of each disk medium is offset from the inner diameter of the disk medium in a same direction along an axis of rotation of the spindle, and a load/unload ramp positioned, based on the offset, to align in correspondence with the outer diameters of the disk media. Thus, the curvature of irregular disk media, such as that associated with thinner and thinner disks, is mitigated by grouping similarly-characterized irregular disks together on a given spindle and compensating the ramp accordingly.

Abstract: Mapping of an avionic network is obfuscated by interposing a network module between an external-access node and a bus of an avionics network. First and second network maps are generated and loaded on the network module. The network map accessible to the external-access node is changed from the first network map to the second network map, to disrupt any reconnaissance of the avionics network.

Abstract: A vehicle network system is configured to detect unauthorized intrusions by a passenger-owned device, and to identify the passenger-owned device based at least in part on stored information representative of network communications. The vehicle network system can be further configured to determine a position of the intruding passenger-owned device within a passenger area of the vehicle and to obtain a name and/or camera image of a passenger associated with the device. The position of the intruding device can be identified based at least in part on communications between the intruding device and one or more network-access devices distributed throughout the passenger area.

Abstract: A method of obfuscating mapping of an avionic network is disclosed, including operatively coupling a network module between an external-access node and an avionics bus, with all communications between the external-access node and the avionics bus passing through the network module. The method further includes generating a first network map identifying network addresses for a first set of components on at least a first portion of the avionics bus, loading the first network map on the network module, and making the first network map accessible to the external access node. The method further includes generating at least a second network map different from the first network map and loading the second network map on the network module. The method further includes changing the network map accessible to the external-access node from the first network map to the second network map.
