Abstract: A method for testing a sensor of a device includes: displaying a test pattern on a display of the device; reflecting, by a reflector disposed over the display, at least a portion of the displayed test pattern; and capturing, by the sensor, a test pattern frame using the displayed test pattern and the reflector.

Abstract: Systems and methods for validating storage media and/or media drives in a storage library using a hidden drive pool and a non-hidden media pool. For example, a storage library can be instructed to perform media/drive validation (MDV) on a selected pool of physical storage media using a selected pool of drive resources. Embodiments handle the pools so that, at least during performance of MDV, the drive resources in the drive pool are not visible to the host applications, but the storage media is still visible and can still be accessed by the host application. For example, the MDV can be performed in such a way that the host application cannot task a drive being used for validation, but the host application can perform operations on storage media in the media validation pool. Further, some embodiments operate in the context of storage library complex-wide validation pools.

Abstract: A power monitoring circuit and method for detecting deviations in the output of a power supply. The power monitor is configured to detect and measure two different types of deviations: transient deviations short surges or spikes in the current drawn by the device being powered and prolonged deviations over a threshold current that may be intentional, temporary increases in the output of the power supply. The power monitor collects information such as the number of each type of deviation, the duration of each deviation and the peak current describing identified deviations. This collected information can then be used, especially during the development phase, to locate the root cause of the deviation. The components of the power monitor used to detect and measure these deviations may be disabled and enabled as needed.

Abstract: Systems and methods are described for logical partitioning of library resources (e.g., storage media resources and/or media drive resources in storage libraries) across a complex of multiple, physically distinct, but logically interconnected data storage libraries. For example, a user selects complex-wide resources to add to one or more library partitions via a graphical user interface displayed on a local console of one of the storage library systems. The partitions can be validated and converted into a partition definition. In some implementations, the partition definition is redundantly stored as a predefined short format in local storage of some or all the storage library systems in the complex. This can minimize the resources used to store the partition definition, provide redundancy for added configuration options and/or in case of certain failures, speed up processing of resource queries, and/or provide other features.

Abstract: Systems and methods are described for media drive operational data retrieval in a storage library in a manner that is asynchronous with respect to other drive-related communications. Embodiments operate in context of a data storage library having a robotic assembly that ferries media cartridges between media slots and media drives to fulfill requests by host systems. The media drives can communicate with a drive controller over a control path and with host systems over a data path. The drive controller can retrieve operational data from the media drive while the drive is effectively idle, and can communicate the retrieved operational data over the control path to the library. Accordingly, retrieval and communication of the drive operational data can be performed via the control path in a manner that is asynchronous with respect to data path and/or other drive-related communications.

Abstract: Methods, treatment compositions and treatment systems for forming a detachable and renewable coating on a receptive surface by a process of applying a treatment composition comprising a plurality of hydrophobically modified fumed silica particles colloidally dispersed in a volatile solvent; allowing the volatile solvent to evaporate; and thereby depositing a protective coating on the receptive surface consisting of a layer of the hydrophobically modified particles. The process provides a coating with dirt- and water-repellency properties that effectively shed dry particulate soils as well as water from the treated receptive surface. The methods, treatment compositions and treatment systems are useful in providing detachable coatings and treated articles featuring surface protective benefits including dirt- and water-repellency, self-cleaning with water, and easier cleaning benefits when applied to a variety of automotive and home surfaces, both interior and exterior.

Abstract: A vehicle with a load sensing hydraulic control system is disclosed.

Abstract: A hydraulic system has several valve sections, each having a directional valve that controls fluid flow from a pump to a hydraulic actuator. A mechanism senses a greatest pressure among the hydraulic actuators to provide a load sense pressure. One valve sections has a pressure compensation apparatus includes a pressure compensation valve that reduces fluid flow between a given directional valve and an associated hydraulic actuator in response to pressure at a control port, and a pressure regulating valve that responds to the load sense pressure and pressure in the associated hydraulic actuator by selectively applying output pressure from the pump and the load sense pressure to the control port.

Abstract: A method for processing compositions, compositions obtained by such a process and methods of use are disclosed for forming a detachable and renewable protective coating which is substantially transparent. The inventive process compositions are produced by making a highly concentrated dispersion of hydrophobically modified silica particles in the presence of an optional, yet preferable, disilazane derivative under high shear conditions. These process compositions are intended to be further diluted to final treatment compositions, optionally while adding other functional ingredients.
