  • Patent number: 7765407
    Abstract: A method for providing centralized user authorization to allow secure sign-on to a computer system is disclosed. In response to a user attempting to boot up a computer system, a message is sent to a trusted server by a hypervisor within the computer to request a new hard drive password for the computer system. If the user is not authorized to access the computer system, a packet is sent by the trusted server to instruct the hypervisor to stop any boot process on the computer system. If the user is authorized to access the computer system, a packet containing a partial hard drive password is sent by the trusted server to the computer system. The packet is then encrypted with a system public key by the computer system to yield the partial hard drive password. The computer system subsequently combines the partial hard drive password with a user password to generate a new complete hard drive password to continue with the boot process.

  • Publication number: 20100146317
    Abstract: An apparatus, system, and method are disclosed for computer system power management. A control module 602 is activated on a computer 200 in response to an event and enters 818 a standby state if the computer 200 is not already 814 in the standby state. A policy module 604 detects 904 a power source of a predetermined type connected to the computer 200 and dictates 908 one or more processors 302 of higher power consumption for a more abundant type of power source such as an AC adapter 314, or one or more processors 304 of lower power consumption for a less abundant type of power source such as a battery 318. A configuration module 606, activated by the control module 602, switches 1004 the computer 200 to one or more processors 302 and 304 of a predetermined power consumption as dictated and exits 1016 the standby state.

  • Patent number: 7697476
    Abstract: An arrangement facilitating the connection of a client to a network through an access point, particularly in an area with overlapping 0.11n channels. Preferably, a client may communicate with two access points and “ask” one of them to stop transmitting long enough so as to facilitate communication with the other access point. Current specifications otherwise provide no workable arrangement for handling overlapping channels.

  • Publication number: 20100081037
    Abstract: The provision of a mode in silver zinc batteries where a user can access extra capacity as an emergency reserve for times when extra capacity is needed. While this temporarily increases capacity, it does not detrimentally affect cycle life over the longer term, and it permits a silver zinc battery to essentially mimic the long term capacity and cycle life characteristics of a lithium ion battery while still affording inherent advantages associated with silver zinc batteries. In a variant embodiment, this ability to temporarily increase capacity is optimally employed at the end of a battery life cycle in a controlled “roll-off” that accords additional cycles of battery service life. In another variant embodiment, the general capability to control capacity is employed to gradually decrease the available capacity of a battery over the life of the battery, to thereby extend the battery service life.

  • Patent number: 7688779
    Abstract: A method, computer program product and system for handling the use of multiple 802.11n channels in a location where there are a small number of available channels. An access point (“access point A”) having a client (“client A”) located solely within its coverage area and another client (“client B”) located within its coverage area and a coverage area of an adjacent access point (“access point B”) may receive a request to hold back 802.11n traffic from client B. Client B sends such a request since it is prevented from communicating with access point B using the 802.11n standard due to the interference from access point A communicating with client A using the 802.11n standard. As a result, access point A switches its standard of operation from using the 802.11n standard to communicate with client A to a standard that uses a bandwidth of 22 MHz (e.g., 802.11b, 802.11a, 802.11g standards).

  • Publication number: 20100039064
    Abstract: An approach is provided that determines whether keyboard power connection points included in a wireless keyboard are connected to system power connection points in a computer system. Power is sent from the computer system to the wireless keyboard. The power is transmitted through the system power connection points to the keyboard power connection points. Keyboard components included in the wireless keyboard are also powered using the power sent from the computer system. If the keyboard power connection points are not connected to the system power connection points, the keyboard components are powered included in the wireless keyboard by using a keyboard battery that is included in the wireless keyboard. One of the keyboard components that receives power is a wireless interface that connects the wireless keyboard to the computer system.

  • Publication number: 20090119785
    Abstract: A system, method, and program product is provided that establishes a shared secret between a computer system and a peripheral device such as a removable nonvolatile storage device or a printer. After establishing the shared secret, the peripheral device is locked. After the peripheral device is locked, an unlock request is received and the shared secret is sent to the peripheral device. The peripheral device then attempts to verify the shared secret. If the shared secret is successfully verified, then the peripheral device is unlocked allowing use of the device by using an encryption key that is made available by the verified shared secret. On the other hand, if the shared secret is not verified, then the peripheral device remains locked and use of the device is prevented.

  • Publication number: 20090089590
    Abstract: Methods and arrangements for managing a flash drive, hard disk, or connection between the two, in a manner to ensure that sensitive data is not decrypted at any time when it would be vulnerable. Accordingly, in a first implementation, the data may preferably be encrypted as it first goes into a flash drive and decrypted when it comes out of the flash drive. In another implementation, the flash drive may be logically bound to the hard disk, so that they would both use the same encryption key. In yet another implementation, if a hard disk is moved to another system, then the flash drive may also preferably be simultaneously moved.

  • Publication number: 20090089808
    Abstract: Arrangements for permitting incoming mail to be transferred from a WAN Drive to a notebook computer hard drive under conditions that are not stressful to the hard drive. Preferably, a WAN card is configured to wake a notebook when mail capacity is full or close to full. Mail is then preferably moved from the flash drive to the hard drive, subject to verification that this will not overly stress the hard drive. In a variant embodiment, the WAN card may preferably be configured to wake a notebook when mail is received at all. Again, mail is then preferably moved from the flash drive to the hard drive, subject to verification that this will not overly stress the hard drive. Once mail is moved to the hard drive, the system preferably runs an embedded email program that allows the user to employ an existing VPN infrastructure.
