Abstract: A method for determining the total leak rate of a system impinged upon by pressure and connected to a control apparatus comprising a valve battery with a test side and a reference side, the valve battery being controllable via a measuring unit, encompasses the following steps: filling the system and the control apparatus with a test medium; closing the connection between the system and the control apparatus; opening a reference leak is on the valve battery; determining the reference leak rate; opening the connection between the system and the control apparatus; and determining the influence of the system on the reference leak rate. A control apparatus comprises a valve battery that is controlled by a measuring unit and is provided with a test side and a reference side which are separated with the aid of a differential pressure sensor and a test and check valve which is connected thereto.

Abstract: Adaptively pre-fetching data includes collecting a first set of statistics based on a number of avoidable read-misses in which data exists that is prior to data being read, collecting a second set of statistics based on a number of avoidable read-misses in which data exists that follows data being read, and collecting a third set of statistics based on said first and second sets of statistics. On the basis of the second set of statistics, a pre-fetch technique is selected from a first technique that pre-fetches data following data being read and a second technique that pre-fetches data before and following the data being read. The first and third set of statistics may be used to determine when to pre-fetch data.

Abstract: A mechanism for manipulation of a substrate over a substantially planar region has at least three, and up to six, degrees of freedom (DOF). The mechanism may be manufactured in various configurations, including triangular, and may use inherent symmetry to reduce the number of distinct components that must be manufactured. The mechanism may use parallelism to reduce the moving mass and thereby achieve higher levels of performance using less expensive motors while dissipating less power.

Abstract: Non-disruptive modification of data in-place includes generating a copy of source data to a holding area. Data modification, such as encryption and/or other transformation process, may be performed on the source data in the source area while I/O operations of applications needing access to the source data is diverted to the data copy in the holding area. Updates to the data copy in the holding area from the continued I/O operations are tracked and the data updates are modified and transferred to the source area. Following successful modification of the source data, the I/O operations of the applications are re-directed back to the source area having the newly modified source data. The holding area may then be freed for subsequent use.

Abstract: Managing data in a server system includes providing a plurality of servers, each having an internal gateway/switch that is accessible from outside the server, providing a plurality of virtual servers on at least some of the servers, where each of the virtual servers is accessible by the internal gateway/switch of the corresponding server, and accessing the data using the internal gateway/switch, where the internal gateway/switch determines which particular one of the virtual servers contain the data and then accesses the particular virtual server to provide the data. Managing data in a server system may also include associating portions of the data to tenants of the server system. Each of the servers may maintain a table that correlates tenants with the virtual servers maintained thereby and the internal gateway/switch may use the table to determine which particular one of the virtual servers contains data for a particular tenant.

Abstract: A cache management system and method monitors and controls the contents of cache memory coupled to at least one host and at least one data storage device where data-units are prefetched and stored into a cache memory in a data-set format, comprising the data-units and meta-data associated with the data units. The meta-data contain time stamp information encoded with information whether the cached prefetched information is available for reuse by additional prefetched data. Prefetched data-units are controlled by executing a first prefetch task to prefetch a first prefetch series of data-units from off-cache. A first prefetch operation is executed to prefetch and store a first selected set of data units. The prefetch task contains three dedicated pointers into cache memory.

Abstract: Restricting access to a device includes obtaining a passphrase for a user, obtaining access credentials for the user, obtaining a PIN value for the user, one-way encrypting at least the access credentials and the PIN using a secret key provided with the device. The user is allowed access to the device if the result of one-way encrypting equals the passphrase. The user is denied access to the device if the result of one-way encrypting does not equal the passphrase. The device may be a storage device. The access credentials may include a username that identifies the user and may include a role for the user. The access credentials may include a time period for which access is allowed. Access may be subsequently revoked in response to the current date and time being greater than the time period for which access is allowed.

Abstract: Scanning a storage device for viruses includes determining physical portions of the storage device that have been modified since a previous virus scan and scanning at least parts of the physical portions for viruses. The physical portions may correspond to tracks of the storage device, sectors of the storage device, and/or to subportions of the storage device. Determining the physical portions of the storage device that have been modified may include creating a table that is indexed according to each of the portions and has entries indicating whether a corresponding one of the portions has been modified, the entries being cleared after a virus scan to indicate that no portions have been modified and setting a specific one of the entries in response to a corresponding one of the portions of the storage device being subject to a write operation. Creating the table may include copying an other table provided by the storage device and/or using an other table provided by the storage device.

Abstract: An apparatus for measuring the velocity of a fluid flow provides electrical charge carriers that are emitted into the fluid flow from an emitter electrode, and wherein an electrical signal caused by this is measured at a sensor electrode. The projection of the envelope of the cross-sectional area of that part of the sensor electrode which projects into the fluid flow into the cross-sectional plane of the fluid flow is small in comparison with the cross-sectional area of the fluid flow at this point, if present at all. The measured current of the sensor electrode is used to serve as a characterizing feature of the velocity of the fluid flow in accordance with a defined allocation function. The measurement method has virtually no delay and can be used in a high temperature and velocity range.

Abstract: A display for creating colored images and text that is visible in incident light. The screen of the display includes pixels arranged in a grid pattern, each pixel having at least three colored mirrors, arranged next to one another or behind one another for the colors red, green and blue or cyan, magenta and yellow. The mirrors are configured from flat, transparent containers, whose interiors are connected to color reservoirs so that the contents of the latter can be displaced by control electronics in such a way that transparent colored liquid is transported from the color reservoirs to the colored mirrors or vice versa. Light sources, which may each be assigned to a single pixel, are located behind the colored mirrors of the pixels, each individual source being electronically controlled. A white or silver reflective layer, which is partially or temporarily transparent, is positioned behind the colored mirrors.
