  • Patent number: 8566110
    Abstract: Hacking a rental computer to use it beyond purchased rental time is prevented by plugging a time card with internal counter into a DIMM socket of the motherboard and encrypting the register locations of the time card with the private key of the motherboard to bind the time card to the motherboard. Thus, if the time card is not detected at boot or if it is removed during operation the computer is disabled. The counter counts down the rented time period as it receives clocking signals, and at the elapse of the purchased period disables the computer.

  • Patent number: 8514709
    Abstract: A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to detect a degraded condition on the backbone network. Upon detecting the degraded condition, the access point selectively dissociates clients on the wireless network. In order to select which clients are dissociated first, a predetermined client dissociation policy is established. The policy can include account priority, bandwidth utilization, elapsed time since last transfer, and, amongst other criteria, whether the client is currently transferring in peer-to-peer mode on the wireless network. Upon detecting the degraded condition, either immediately or after a predetermined delay to ensure that the degraded condition is not temporary, clients on the wireless network are dissociated according to the preestablished policy.

  • Patent number: 8312534
    Abstract: A system, method, and program product is provided that initializes a counter maintained in a nonvolatile memory of a security module to an initialization value. The security module receives requests for a secret from requesters. The security module releases the secret to the requesters and the released secrets are stored in memory areas allocated to the requesters. A counter is incremented when the secret is released. Requestors send notifications to the security module indicating that the requestor has removed the secret from the requestor's memory area. The security module decrements the counter each time a notification is received. When the computer system is rebooted, if the counter is not at the initialization value, the system memory is scrubbed erasing any secrets that remain in memory.

  • Patent number: 7936676
    Abstract: A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to balance loads by deferring association of new clients and thereby directing clients to associate with alternative access points having improved backbone connectivity. Where the client is unable to find an alternative access point, the client will eventually make a second association request to the access point. The access point, in identifying the second association request of the client, proceeds to associate the client in response to the second association request. Specific time limits can be imposed relative to the second association request.

  • Patent number: 7864670
    Abstract: A method and corresponding network interface device for communicating between devices connected to a LAN includes attempting to communicate between the network devices over an initial subset of the network media wires. If the communication fails, a subsequent subset of media wires is selected. The wires of this subsequent subset differ from the wires of the initial subset. If the attempted communication succeeds, the current subset of network media wires is used as the media over which subsequent network data is transmitted. Attempting to communicate over the media may include sending an initialization sequence such as an Ethernet Auto-negotiate sequence. In one embodiment, the network media is implemented as 8 wires of CAT 5 cabling suitable for use with a Gigabit Ethernet. In this embodiment, any subsequent subsets of the network media wires may consist of 4 of the 8 wires over which 100 Mbps Ethernet operation may occur.

  • Patent number: 7817370
    Abstract: A system and method to avoid disk lube pooling is presented. A track access monitor tracks the number of times that a program accesses a particular track located on a hard drive. When the track access monitor determines that the number of track accesses to a particular track exceed a track access threshold, the track access monitor invokes a sequence of events to scan adjacent tracks in order to uniformly redistribute lubrication over the hard drive. In one embodiment, the track access monitor incrementally performs the adjacent track scanning during hard drive idle periods, such as when the system waits for a password from a user or when the operating system conserves power and idles the hard drive due to lack of activity.
