Abstract: A drill tool includes a bit body, at least one bearing shaft extending from the bit body and a cone mounted for rotation on the bearing shaft. An outer bearing surface of the bearing shaft includes a non-loading zone. A first groove and a second groove are formed in the outer bearing surface at the non-loading zone. The first and second grooves are both circumferentially offset from each other and axially offset from each other. One or more of the grooves includes an opening for making a fluid connection to an internal lubricant channel within this bearing shaft. The circumferential and axial offsetting of the first and second grooves define a plurality of attenuation zones that function to restrict propagation of a cone pumping pressure pulse towards a sealing system of the drill tool.

Abstract: A drill tool comprises includes a bit body, at least one bearing shaft extending from the bit body and a cone mounted for rotation on the bearing shaft. The bearing system for the tool includes a radial thrust bearing from which cone pumping pressure pulsation originates. A lubricant sealing system including an annular seal gland and a seal ring retained within the annular seal gland functions to retain lubricant in the bearing system. The tool further includes a lubricant cone pumping pressure restrictor system formed by an annular gland (separate from the annular seal gland) and a pressure restricting ring retained within the annular gland. The lubricant cone pumping pressure restrictor system is positioned between the radial thrust bearing system and the lubricant sealing system and is adapted to attenuate cone pumping lubricant pressure pulsation from acting on the seal ring retained within the annular seal gland.

Abstract: Integrated MOSFET current sensing for fuel-gauging. A 1st MOSFET through which the current is to be sensed is coupled to a 2nd MOSFET of the same type, the 2nd MOSFET being biased to have the same resistance as the 1st MOSFET. The 2nd MOSFET has a much smaller area than the 1st MOSFET, and is coupled to a current source representing a maximum current through the 1st MOSFET. The voltage across the 1st MOSFET relative to the voltage across the 2nd MOSFET provides a measure of the current through the 1st MOSFET. Various embodiments are disclosed, including embodiments in battery packs to eliminate the need for additional and expensive external components.

Abstract: The present invention is an impact vehicle restraint with a constant-torque, multi-mode electric motor to secure the ICC bar of a trailer to a loading dock. A mounting plate anchors a carriage to the front of the loading dock. The carriage is biased to a raised position and has a pair of spaced shear plates that house a hook. An electric gearmotor rotates the hook between retracted and extended positions. When extended, the hook secures and holds the ICC bar to the dock. The motor has a higher power level or mode to raise and lower the hook, and a lower power level or mode to continuously adjust the position of the hook and keep it in forced engagement with the ICC bar during the process of loading and unloading the trailer. A control system cycles the motor and hook through an operating cycle.

Abstract: A system that associates physical locations with network-linked devices in a network to which such devices are connected. This system employs a variety of techniques for establishing device location. The system configuration can vary and can include any type of data network, including LANs, MANs, Wide Area Networks (WANs), Personal Area Networks (PANs), and Home Networks. The system provides location information for particular devices to the network devices and management, and may be used in any of a variety of ways to improve configuration accuracy, control, and security. The location information may also be used to control or secure a device itself.

Abstract: One or more trusted network devices within a data network infrastructure determine a physical location of a client device requesting access to the data network infrastructure. A trusted physical location is generated and associated with the client device. The approach can include determining whether a candidate network device is a trusted network device based on a likelihood that the candidate network device can be modified to provide false physical location data. The approach also can include determining a response for an access request by the client and controlling network resources provided to the client based on the trusted physical location.

Abstract: A system and method to respond to intrusions detected on a network system including attached functions and a network infrastructure. The system includes means for receiving from an intrusion detection function information about intrusions, a directory service function for gathering and reporting at least the physical and logical addresses of devices of the network infrastructure associated with the detected intrusions, and a plurality of distributed enforcement devices of the network infrastructure for enforcing policies responsive to the detected intrusions. A policy decision function evaluates the reported detected intrusions and makes a determination whether one or more policy changes are required on the enforcement devices in response to a detected intrusion. A policy manager function configures the distributed enforcement devices with the responsive changed policy or policies.

Abstract: Systems and methods are provided for a media device that controls input and output characteristics based on one or more associated conditions.

Abstract: A computer-implemented method and computer program product for providing data that includes location-based access control information concerning a data relay device located within a network infrastructure. The data relay device is loaded with one or more features, such that the one or more features loaded are dependent, at least in part, upon the location-based access control information.

Abstract: Data is provided with location-based access control information. Access to the data at a physical location is then limited according to the location-based access control information. A physical location of a device accessing the data can be determined, and the limiting of the access is then according to the determined physical location. The data can be provided in encrypted form, and limiting access to the data includes enabling decryption of the data according to the physical location.

Abstract: A system and method for rapidly responding to triggering events or activities in a network system. The system includes a policy enforcement function, a policy manager function, and one or more network devices of the network system. The policy enforcement function includes one or more installed policy sets and/or policy enforcement rule sets suitably responsive to triggering events or activities. Upon detection of a trigger, the policy manager function analyzes the trigger and selects one or more appropriate policy sets and/or policy enforcement rule sets deemed to be responsive to the trigger. Each set has a unique rapid response identifier. The policy manager function signals for implementation of the one or more policy and/or rule sets, based on one or more rapid response identifiers, which are enforced through the policy enforcement function. The policy enforcement function may be a part of one or more of the one or more network infrastructure devices for implementing the policy change.
