Abstract: A hydraulic mount apparatus (20) for supporting a vibration source is disclosed. The mount apparatus (20) includes a housing (22) that defines a housing chamber (24) separated by a partition assembly (62) into a pumping chamber (64) and a receiving chamber (66), each containing a magnetorheological fluid (68). A flexible body (48) is partially disposed in the pumping chamber (64) for deforming elastically in response to vibrations caused by an external excitation. A fluid passage (106) extends between the pumping chamber (64) and the receiving chamber (66) for passing the fluid therebetween during low frequency vibrations. A piezostack actuator (118) partially extends into the pumping chamber (64) for moving within the pumping chamber (64) for varying the volume of the pumping chamber (64) to prevent a pressure increase in the pressure chamber to substantially cancel relatively high frequency vibrations.

The vaccines may also include a CD 154 polypeptide capable of binding to CD4Q. Also provided are methods of enhancing an immune response against Apicomplexan parasites and methods of reducing morbidity associated with infection with Apicomplexan parasites.

Abstract: A method and apparatus for determining likelihood of rollover of a vehicle and/or mitigating rollover of the vehicle is responsive to measured vehicle lateral acceleration and a measured one of vehicle roll rate and vehicle suspension displacements to derive estimates of roll angle and roll rate. First, preliminary, estimates of roll angle and roll rate are derived and used as pseudo-measurements in a dynamic, closed loop observer equation which represents a model of the vehicle in a first roll mode for roll angles small compared to a reference value indicating two wheel lift-off and a second roll mode for roll angles at least near a reference value indicating two wheel lift-off. The observer equation has parameters and gains with values for each mode stored as a function of roll angle index derived from measurements and pseudo-measured values. The observer equation produces second, improved values or roll angle and roll rate together indicating the likelihood of vehicle rollover.

Abstract: A system for promoting and distributing digital content over a data network includes a source node connected to a data network; a target node connected to the data network; and a server application running on the source node for concatenating digital content for distribution to the target node. In a preferred embodiment, the digital content distributed to the target node is a multipart file including at least an executable replication of the server application, an executable for installation of the digital content, and a module for promoting the existence of the content and new point of distribution thereof to at least one other target node.

Abstract: A system for providing network security through manipulating data connections and connection attempts over a data-packet-network between at least two network nodes is provided. The system includes a system host machine, a first software application residing on the host machine for detecting and monitoring connection activity, a data store for storing connection related data, and a second software application for emulating one or more end nodes of the connections or connection attempts. In a preferred embodiment the system uses the detection software to detect one or more pre-defined states associated with a particular connection or connection attempt including states associated with data content transferred there over and performs at least one packet generation and insertion action triggered by the detected state or states, the packet or packets emulating one or more end nodes of the connection or connection attempt to cause preemption or resolution of the detected state or states.

Abstract: An arrangement is provided for welding together current carrying members of an electrical distribution device that are made of similar conductive material. The arrangement includes an electron beam gun capable of generating an electron beam sufficient to penetrate and heat the material, thereby providing mixing of the material to form a joint which is constructed substantially of a portion of each of the current carrying members.

Abstract: An improved active brake control method which compensates for the effects of a banked road surface under both steady state and transient operating conditions of the vehicle. The control includes an observer for estimating the lateral velocity of the vehicle as a means of determining vehicle slip angle, and a time derivative of the estimated lateral velocity is used along with measured values of lateral acceleration, vehicle speed and yaw rate to compute the lateral acceleration component due to the banked road surface, referred to as the bank acceleration. The bank acceleration, in turn, is then used to correct the values of measured steering angle and the measured lateral acceleration used (1) to develop the desired yaw rate, slip angle and lateral acceleration, and (2) to estimate the surface coefficient of adhesion and slip angle. Partial compensation can be achieved by applying suitable gain factors to the computed bank acceleration, if desired.

Abstract: A brake system control for use in a vehicle with wheels, wheel brakes and a body, comprising the steps of: measuring a plurality of vehicle parameters; responsive to the measured parameters, determining at least a vehicle yaw rate, a vehicle slip angle, a desired yaw rate and a desired slip angle; responsive to the measured parameters, estimating a coefficient of adhesion between the vehicle wheels and a road surface; implementing a control responsive to the vehicle yaw rate and the desired yaw rate with a first authority and responsive to the vehicle slip angle and the desired slip angle with a second authority, wherein the first authority increases as the estimated coefficient of adhesion increases and decreases as the estimated coefficient of adhesion decreases; and controlling the wheel brakes responsive to the control to reduce a first difference between the vehicle yaw rate and the desired yaw rate and to reduce a second difference between the vehicle slip angle and the desired slip angle.
