  • Patent number: 9648038
    Abstract: Requests to send data from a first host within a network of hosts are monitored against a record of destination hosts that have been sent data in accordance with a predetermined policy. Destination host identities (not the record) are stored in a buffer. The buffer size is monitored to determine whether requests from the first host are pursuant to viral activity therein.

  • Patent number: 9221172
    Abstract: Redundant robotic manipulators may be constrained in their motions during operation in a gravity-compensated mode by applying, in addition to gravity-compensating torques, constraining torques to one or more of the joints. The constraining torques may urge the manipulator to a specified canonical posture, and may be modeled by virtual springs attached to the constrained joints.

  • Patent number: 9079305
    Abstract: Sensors associated with a robot or sub-system thereof (e.g., a series elastic actuator associated with a robot joint) may be monitored for mutual consistency using one or more constraints that relate physical quantities measured by the sensors to each other. The constraints may be based on a physical model of the robot or sub-system.

  • Patent number: 9043025
    Abstract: In various embodiments, safe collaboration between a robot and humans is achieved by operating the robot continuously at or below a first threshold speed at which any collisions with a person's arms do not cause harm, and, upon detection of the person's torso or head within a danger zone around the robot, reducing the speed to or below a second threshold at which any collisions with the person's torso or head do not cause harm.

  • Patent number: 8505096
    Abstract: One embodiment of an apparatus for monitoring from a first location in a computer network traffic emanating from a source at a second location in the network, the apparatus comprising means at the first location for detecting traffic emanating from the source and means for monitoring the number, per unit time, of distinct destinations of the traffic that lie outside a first set specifying familiar destinations of the traffic. This monitoring process can trigger various responses such as the isolation of the source from the network. Other systems and methods are also provided.

  • Patent number: 8392995
    Abstract: A method of operating a computing entity in a network having a log mapping computing entity network addresses to vulnerabilities, the method comprising the steps of: using the entity's network address, searching the log to establish what vulnerabilities the entity has; and if the log indicates the entity has a vulnerability, sending data identifying a user of the entity to an administrator of the network.

  • Patent number: 8230116
    Abstract: Access to a data processor is controlled by determining if a requested function command conforms to a set of parameters, the set of parameters being derived from previously executed function commands. If the requested function command does not conform to the set of parameters the data processor is controlled to temporarily hold the execution of the requested function commands.

  • Patent number: 7796515
    Abstract: A method of operating a first host within a network of a plurality of hosts. Over the course of a first time interval, requests received at the first host from a second host to send data to destination hosts are monitored. Identities of destination hosts monitored during the first time interval are compared with destination host identities in a record. Then, either data relating to requests which identify a destination host not in the record are stored in a storage buffer. Or the passage of data from the second host to the destination host within the network is limited over the course of the first time interval, so that during the first time interval the second host is unable to send data to more than a predetermined number of hosts not in the record.

  • Patent number: 7558216
    Abstract: A method and apparatus for controlling communications in a data network comprises detecting a request to initiate communication between a data processor and the network and determining if the communication request is abnormal and if so, controlling the data processor to degrade the resulting communication.

  • Patent number: 7437758
    Abstract: Propagation of viruses in a network having a plurality of hosts is restricted. Network activity of a first host of the plurality is monitored, and a first record established which is at least indicative of identities of hosts within the network contacted by a first host. Contact of the first host to other hosts within the network is limited over the course of a first time interval, so that during the first time interval the first host is unable to contact more than a predetermined number of hosts not in the first record. The method further includes an additional selection process for determining hosts of the plurality the first host is allowed to contact.
