  • Publication number: 20150134265
    Abstract: A distributed network system and method includes a processing unit configured to manage safety data for a plurality of medical devices, a database software component in communication with the processing unit, and a monitoring software component in communication with the processing unit. The monitoring software component is configured to monitor a number of messages between a number of medical devices and the processing unit, to process performance parameters to generate an overall performance index, and to generate an output that is viewable by a user. The output includes relative contributions of each of the performance parameters to the overall performance index, where the overall performance index is generated using a weighting factor associated with each of the performance parameters. The performance parameters include the number of messages waiting to be processed, which has the largest weighting factor, and a disk queue length, which has the smallest weighting factor.

  • Patent number: 9015090
    Abstract: Identifying a questionable network address from a network communication. In an embodiment, a network device receives an incoming or outgoing connection request, a web page, an email, or other network communication. An evaluation module evaluates the network communication for a corresponding network address, which may be for the source or destination of the network communication. The network address generally includes an IP address. The evaluation module determines one or more properties of the network communication, such as time of day, content type, directionality, or the like. The evaluation module then determines whether the properties match or are otherwise allowed based on properties specified in the white list in association with the IP address.

  • Patent number: 8621604
    Abstract: Identifying a questionable network address from a network communication. In an embodiment, a network device receives an incoming or outgoing connection request, a web page, an email, or other network communication. An evaluation module evaluates the network communication for a corresponding network address, which may be for the source or destination of the network communication. The network address generally includes an IP address and a port number. The evaluation module checks a predefined white list for the network address to determine whether the network address is valid. Depending on the result, the evaluation module sets an indicator for preventing, allowing, or warning about the network communication. A category code, security code, organization code, or function code, may also be checked against the white list to ensure a valid network node is not compromised. A domain name may also be determined from the network address to further validate the network communication.

  • Patent number: 8297385
    Abstract: A dual wheelend for an axle assembly having a rotatable axle shaft. The wheelend comprises a spindle defining a first axis. An intermediate hub is supported on the spindle for rotation about the first axis during rotation of the axle shaft. An inner wheel hub and an outer wheel hub are adjacent one another and are each supported on the intermediate hub for rotation about the first axis. A differential mechanism interconnects the inner and outer wheel hubs. A pin is disposed through a pinion along a second axis and couples the differential mechanism to the intermediate hub for driving the wheel hubs during rotation of the intermediate hub and permitting relative rotation between the wheel hubs relative to the intermediate hub. The pin includes proximal end with a head disposed on the proximal end for engaging the pinion and sandwiching the pinion between the head and the intermediate hub.

  • Patent number: 8214899
    Abstract: An online service gathers information about a user's access to an online account and makes that information available to the account owner and/or other authorized user. When an online account is accessed, the online service logs a time stamp, a network address from which the account was accessed, a port number, a user ID, routing data, and/or other access data. The online service may use the access information to obtain address ownership name, geographic location, and/or other ownership information associated with the account access. The accessing client also stores access data. The client, account owner, and/or another decision maker evaluates all, or portions of information to detect unauthorized access to the account. The decision maker may dynamically evaluate and display the access data or later compare log files of the online service and the account owner's local log file.

  • Patent number: 8151913
    Abstract: An axle assembly for a vehicle comprising a stationary spindle and a rotatable axle shaft. An intermediate hub is supported on the spindle. Adjacent inner and outer wheel hubs are supported on the intermediate hub. A differential mechanism interconnects the inner and outer wheel hubs for driving both of the wheel hubs and for permitting relative rotation between the wheel hubs. At least one differential bushing is disposed between the differential mechanism and the intermediate hub. A gear reduction system interconnects the intermediate hub and the axle shaft for providing torque multiplication. A wet disc brake device is coupled between the spindle and the intermediate hub.

  • Publication number: 20070055749
    Abstract: A method and system for identifying a network resource such as a phishing website. In an embodiment, a web browser receives a web page that includes a resource identifier, such as a URL, to enable a user to access the network resource. An anti-phishing module accesses the network resource and receives a network address, such as an IP address and a port number. The anti-phishing module accesses a database, such as an assigned name database, to obtain ownership information, such as an owner name and country code, associated with the network address. The ownership information is checked to determine whether the network address is associated with a valid owner that is related to the resource identifier. If the network addresses ownership is not trusted, a warning is optionally provided, indicating that the resource identifier may be directed to a phishing.

  • Publication number: 20050263985
    Abstract: A tandem axle suspension assembly includes a pair of walking beams disposed substantially parallel to a vehicle longitudinal axis supporting first and second axles. A link plate is pivotally attached to each of the walking beams and is pivotal about an axis transverse to the longitudinal axis. A first and a second link include pivotal connections between the link plate and a vehicle frame member. Vertical movement of the walking beams causes a corresponding rotation of the link plate to compensate for longitudinal displacement of the pivotal links with the first and second links and minimize longitudinal displacement of the walking beams.

  • Publication number: 20050263986
    Abstract: A vehicle suspension assembly includes a control rod pivotally connected between a vehicle frame and an axle. The control rod controls longitudinal and vertical movement of the axle. A spring member is pivotally connected to the frame and fixed to the axle. Air spring assemblies are mounted between the axle and frame. The rigidly mounted spring member exerts torsion forces on the axle to counter roll forces and the air spring assemblies provide favorable ride characteristics adaptable to various trailer load conditions.

  • Publication number: 20050161292
    Abstract: An axle assembly includes a shaft supported for rotation within an axle housing. The housing is mountable to a trailing arm pivotal relative to a vehicle. The axle shaft includes a hub mounted on a first end for mounting of a wheel. A rotor is mounted to a second portion of the axle. The second portion of the axle shaft and rotor is mounted at a position inboard of any portion of the wheel rim. Mounting of the rotor outside any portion of the wheel rim allows the rotor, caliper, and actuator to be configured without constraints on size and cooling concerns inherent with brake assemblies positioned within the circumference of the wheel rim.
