  • Publication number: 20100224352
    Abstract: An apparatus controls a temperature of a device by circulating a fluid through a heat sink in thermal contact with the device. The apparatus includes an adjustable cold input, which inputs a cold portion of the fluid having a first temperature, and an adjustable hot input, which inputs a hot portion of the fluid having a second temperature higher than the first temperature. The apparatus further includes a chamber, connected to the cold input and hot input, in which the cold and hot portions of the fluid mix in a combined fluid portion that impinges on the heat sink. The combined fluid portion has a combined temperature that directly affects a temperature of the heat sink. The cold input and hot input are adjusted to dynamically control the combined temperature, enabling the heat sink temperature to compensate for changes in the device temperature, substantially maintaining a set point temperature of the device.

  • Patent number: 7737982
    Abstract: A method and system for minimizing an amount of data needed to test data against subarea boundaries in spatially composited digital video. Spatial compositing uses a graphics unit or pipeline to render a portion (subarea) of each overall frame of digital video images. This reduces the amount of data that each processor must act on and increases the rate at which an overall frame is rendered. Optimization of spatial compositing depends on balancing the processing load among the different pipelines. The processing load typically is a direct function of the size of a given subarea and a function of the rendering complexity for objects within this subarea. Load balancing strives to measure these variables and adjust, from frame to frame, the number, sizes, and positions of the subareas. The cost of this approach is the necessity to communicate, in conjunction with each frame, the graphics data that will be rendered. Graphics data for a frame is composed of geometry chunks.

  • Patent number: 7546640
    Abstract: Methods, systems, and media are disclosed for determining access rights to a resource managed by an application. One embodiment includes receiving a request by the application, wherein the request comprises an action a user seeks to perform on the resource. Further, the embodiment includes locating, based on the request, the resource in a structure having groupings of resources, wherein the groupings include a grouping having the resource. Typically the groupings comprise files having mappings of resources to assigned groups, and each group has an associated authorization table mapping roles or policies to users. Further still, the embodiment includes reading an authorization table associated with the grouping having the resource, and determining whether to grant the access rights for performing the action on the resource.

  • Publication number: 20090037196
    Abstract: A method, computer program product, and apparatus for receiving a postal mail item. The postal mail item is received. The postal mail item contains a radio frequency identifier identifying the sender of the postal mail item. Responsive to receiving the postal mail item in the mailbox, the radio frequency identifier of the postal mail item is scanned with a scanner to identify the sender of the postal mail item. A determination is made whether the sender of the postal mail item is in a junk mail list. The junk mail list includes a list of senders accessible to a processor in the scanner.

  • Patent number: 7483914
    Abstract: A method is presented for processing names by a naming service. A naming service obtains an application name for an application along with at least one deployment attribute for a deployment of an instance of the application within a data processing system. The naming service generates an application-based name for the instance of the application; the application-based name represents a context within a naming system that is supported by the naming service, and the application-based name is a compound name that includes the application name and at least one deployment name for a deployment attribute. A deployment attribute is a metadata value, such as a deployment identifier or version identifier, that characterizes a manner in which the instance of the application is deployed within the data processing system.

  • Publication number: 20080295147
    Abstract: An approach to handling integrated security roles is presented. An upstream application includes one or more role-mapping requirements that correspond to an upstream security role and a downstream security role. The upstream security role is expanded by adding an upstream security role identifier in a downstream application's role-mapping table or by adding upstream user-to-role mappings to a downstream application's role-mapping table. When an upstream security role is expanded, a user assigned to the upstream security role automatically has access to role-mapped downstream applications.

  • Publication number: 20080222719
    Abstract: Methods, systems, and media are disclosed for determining access rights to a resource managed by an application. One embodiment includes receiving a request by the application, wherein the request comprises an action a user seeks to perform on the resource, and locating, based on the request, the resource in both a containment relationship graph and in a structure having groupings of resources, wherein the groupings comprise a grouping having the resource. Further, the embodiment includes traversing a vertex of the containment relationship graph, wherein the vertex comprises a generational resource of the resource, and reading an authorization table associated with a grouping having the generational resource in the groupings. Further still, the embodiment includes determining whether to grant the access rights for performing the action on the resource.

  • Publication number: 20080159536
    Abstract: An approach is provided that allows an administrator to set a new password at a wireless access point, such as a traditional WAP or a wireless router. The wireless access point creates a message that includes the new password. The message is encrypted using the old password that was previously set for the wireless network. The encrypted message is wirelessly transmitted from the wireless access point to the active client devices (those clients currently accessing the wireless network). The clients decrypt the message using the old password that was previously provided to the clients. The clients retrieve the new password from the message. The clients construct a new message that is encrypted using the new password. The new message is wirelessly transmitted from the clients to the wireless access device and serves as an acknowledgement.

  • Publication number: 20080072316
    Abstract: Methods and systems are provided for dynamically altering the capabilities of a software application in response to a request from a user to perform an action in the application. Based on the user's security role, the software application is reconfigured by either granting access to the user to an existing component of the application, or if no suitable component is available, adding an external vendor component to the software application which is suitable for performing the requested action.

  • Patent number: 7337435
    Abstract: Methods, systems, and computer program products for migrating configuration data from an existing program to a replacement program, in response, for example, to a command by an external agent. In preferred embodiments, an existing program is modified according to the invention to add functionality to obtain pertinent configuration data from such sources available to the existing program as its internal tables, configuration files, and run-time commands, and then to write a configuration file containing configuration data formatted for use by the replacement program. The program's internal tables may often contain configuration data which is not always available to the replacement program e.g. command line parameters, data provided through receipt of messages from other programs, etc. The invention advantageously makes voluminous formatted configuration data available to the replacement program in order to expeditiously provide a basis for its initial operation after installation.
