  • Patent number: 8254257
    Abstract: A priority server for a provider network includes a traffic volume detection module, a traffic analyzer module, and a rules module. The traffic volume detection module receives operational information from the provider network and determines that a host is experiencing a flash event based upon the operational information. The traffic analyzer module determines that the flash event is not a distributed denial of service attack on the host. When it is determined that the flash event is not a distributed denial of service attack, the rules module provides a priority rule to an access router that is coupled to the host. The priority rule is based upon a characteristic of packets routed in the provider network that are associated with the flash event, and the characteristic is determined not solely by information included in the packets.

  • Patent number: 8243563
    Abstract: An information handling system includes an optical disc drive. The optical disc drive is connected to an auxiliary power source so that a drive tray of the optical disc drive can be opened or closed, or a disc inserted or ejected from the optical disc drive when the information handling system is in a low-power mode. In response to these actions in the low-power mode, information is stored to record that the drive tray has been opened or closed. Accordingly, when the information handling system returns to a normal mode, it can take appropriate action, such as dismounting a logical volume associated with a disc that was previously in the drive. Because the optical disc drive can be physically accessed in the low-power mode, the information handling system does not have to enter the normal power mode in order for discs to be retrieved or inserted.

  • Patent number: 8208534
    Abstract: Media codec devices obtain and decode media signals and then distribute them to downstream devices. The media codec devices may obtain media signals from multiple service providers or other sources, including protected media signals. The media codec devices may be decoupled from the source of the media signals by maintaining a managed collection of decoder information including decoder keys, decryption algorithms, and codecs within a memory of a decoder, where such decoder information may be updated by adding new decoder information and/or removing existing decoder information to add or lose service providers while the media codec device is in the possession of the consumer. The media codec device may be decoupled from playback devices at the premise of the consumer by utilizing media transfer devices that receive decoded media signals from the media codec device and transfer them for ultimate delivery to playback devices.

  • Patent number: 8201163
    Abstract: In a Uniform Extensible Firmware Interface (UEFI) environment, a system management mode (SMM) driver and a non-SMM driver may be installed for the same hardware device. Until the SMM driver is available, the non-SMM driver is configured to conduct input/output (IO) transactions directly with the hardware device. The non-SMM driver can utilize native UEFI services to receive a notification that the SMM driver is available. Upon receiving such notification, (or if the SMM driver was already available before the non-SMM driver), the non-SMM driver is reconfigured to redirect all IO requests to the SMM driver, which then conducts the corresponding IO transactions directly with the hardware device. Redirecting all non-SMM IO requests for a hardware device to the SMM driver for the hardware device limits direct access to the hardware device to only one driver, the SMM driver, thereby facilitating the integrity or atomicity of IO transactions.

  • Patent number: 8193466
    Abstract: An information handling system can include a base, a printed circuit board including a capacitive switch, and a cover. The printed circuit board can be attached to the base, and the cover can lie adjacent to the printed circuit board. The capacitive switch can be configured to change state when an object is close to the cover. The cover can be configured such that it can be detached from the remainder of the information handling system while the printed circuit board remains attached to the base. The configuration of the printed circuit board and cover can be particularly useful when maintaining a keyboard or a touch pad or when replacing the cover.

  • Patent number: 8189749
    Abstract: A technique for handling messages in a messaging system includes receiving a playback request for a message. A first user control input that is associated with the playback request for the message is then received. The first user control input corresponds to a fast-forward function or a rewind function. It is then determined whether a second user control input, which corresponds to a same function as the first user control input, is received prior to expiration of a first time period. The playback request for the message is then serviced using a first offset when the second user control input is not received prior to expiration of the first time period or using a second offset, which is different than the first offset, when the second user control input is received prior to expiration of the first time period.
