Abstract: Systems and methods for pre-authenticating a mobile client in a wireless network. Authenticators in a secured section of the wireless network share a master key generated during an authentication session between a mobile client and an authentication server. The shared master key is not allowed to reside on any devices located outside the secured section of the network. Accordingly, the likelihood that the master key may be hijacked is essentially eliminated. A first session encryption key is derived from the master key and used by the mobile client and a first access point during a first communications session. When the mobile client roams to a second access point, a fast authentication process is performed. The fast authentication process retrieves the shared master key and generates a second session encryption key. A full authentication process between the authentication server and the mobile client is not required.

Abstract: An integrated lancing test strip device includes a lancet configured to form an incision in tissue and a test strip coupled to the lancet for analyzing body fluid. A retention mechanism acts as a detent to hold the lancet in a static position relative to the test strip before forming the incision. The retention mechanism is configured to release the lancet for retracting the lancet relative to the test strip to reduce smearing of body fluid by the lancet during collection of the fluid with the test strip. In one form, the retention mechanism includes breakable tabs that are broken to release the lancet, and the lancet is retracted via translational movement. The retention mechanism in another form includes one or more dimples that release the lancet when the lancet is retracted via rotational motion. In a further form, the entire integrated device is rotated to collect fluid.

Abstract: One embodiment of the present invention provides a system that facilitates configuring a database. During operation, the system requests database configuration information from a directory server that stores configuration information for a plurality of database instances. In response to this request, the system receives the database configuration information, and configures the database in accordance with the database configuration information received from the directory server. This enables the database server to be configured without requiring manual configuration operations by a database administrator.

Abstract: One embodiment of the present invention provides a system that facilitates using query signatures to provide security for a database system. During operation, the database system receives a query. Next, the system parses the query to determine a signature for the query. This signature specifies a structure based on operators for the query and is independent of the value of literals in the query. The system then determines if the signature can be found in a signature cache which contains valid query signatures. If so, the system processes the query.

Abstract: Sending control information that is associated with a statement that controls how the statement is processed is disclosed. The information is available to the server even after the window session is closed. The information may be contained in a tag appended to the statement. In an embodiment, the information may be viewed by an administrator. The information may determine aspects of how the statement is executed that is not controlled by the execution engine. For example, the information may relate to security access, priority, quality of service, scheduling, and or use supplied routines.

Abstract: Multi-table access control is disclosed that limits access to tables when a requirement for access to multiple columns is detected, where the multiple columns includes at least one column from one table and another column form another table. In an embodiment, the detection of the requirement for access to multiple columns triggers a policy to rewrite the query to include a condition expression that limits access to the multiple columns to those that are entitled to access.

Abstract: Returning rows having column values masked is disclosed. In response to receiving a database command, a modified database command is created that specifies whether to mask a value by returning a mask of the value instead of the value. In an embodiment, the condition expression is included in a policy function that is referenced by a policy. In an embodiment, the policy determines how the condition expressions are used. The condition expression may be used to determine which column values to mask. The condition expression may also be used to filter which rows are returned.

Abstract: A de-interlacer includes recursive motion history map generating circuitry operative to determine a motion value associated with one or more pixels in interlaced fields based on pixel intensity information from at least two neighboring same polarity fields. The recursive motion history map generating circuitry generates a motion history map containing recursively generated motion history values for use in de-interlacing interlaced fields wherein the recursively generated motion history values are based, at least in part, on a decay function.

The two structures may be coupled using surface mount techniques as one example, so that the temperatures utilized may be compatible with many MEMS applications. Electrical interconnection layers in one or the other of these structures may be utilized to allow electrical interconnections from the exterior world to the MEMS components within the cavity.

Abstract: A method for wirelessly transmitting data under a wireless protocol is contemplated. An access point topology map is constructed or input. The topology map relates access points that have overlapping coverage areas, and thus, are prone to have remote devices travel between them. The relationships are used to send session parameters regarding a particular wireless device to the access points or gateways that border the zone in which the particular device is presently in. In this manner, information regarding the particular wireless device and open sessions may be present at such gateways or access points if and when the wireless device enters the zone that the gateway or access point is responsible for.

Abstract: A device for wirelessly transmitting data under a wireless protocol is contemplated. A remote wireless network device initiates a session with a network. In this manner, information is sent to a gateway associated with the access point that couples the remote wireless network device to the network. When the remote wireless network device moves, data is tunneled between the succeeding gateway and the original gateway, but for those sessions opened at the original gateway. Any sessions associated with the remote wireless network device at the new gateway are processed and maintained by the new gateway without tunneling the data.

Abstract: A method and method and apparatus for data re-arrangement includes the steps of receiving output pixel coordinates (X, Y) and obtaining an input pixel offset value (&Dgr;S, &Dgr;T), wherein the output pixel coordinate represents a location for a two dimensional matrix.

Abstract: A proportional force input apparatus for an electronic device includes a mechanism operable by a user of the electronic device, such as a stylus inserted into a spring-loaded socket of the device. The mechanism provides a tactile feedback to the user proportional to a force applied by the user. A variable strength sensor detects the force applied by the user to the mechanism and converts this to an electrical signal proportional to the force applied by the user. A processor operates to input the electric signal from the variable strength sensor and provide force information to an application running on the electronic device. Optionally, a second sensor can detect rotation of the stylus. As a result, a stylus can be used to provide vector information to an application such as a game.
