Method and apparatus for exchanging event information between computer systems that reduce perceived lag times by subtracting actual lag times from event playback time

Mechanisms and techniques provide the system that allows a sending computer system to capture and store event information related to events that transpire on a sending computer system in event batches. The event information can include event functionality related to event object in the timestamp related to the event. Periodically, in response to the occurrence of the batch transfer condition, the sending computer system transmits an event batch monthly computer network for receipt by a receiving computer system. The event batch may be processed through a collaboration adapter on the networks while prior to being send to the receiving computer system. Upon receipt of an event batch at the receiving computer system, the receiving computer system can compute a lag time required to receive the event batch. The receiving computer system can then recreate events based on the event information in the event batches while compensating for network lag time incurred during transmission of the event batch between a sending and receiving computer systems. By compensating for network lag during the recreation or playback of events, the system of the invention avoids the receiving computer system from reproducing events in a choppy or discontinuous manner or from getting left behind during event recreation due to accumulations of network lag time.

Methods and apparatus for network message traffic redirection

Conventional methods of addressing a Distributed Denial of Service attack include taking the target node offline, and routing all traffic to an alternate countermeasure, or “sinkhole” router, therefore requiring substantial lag time to reconfigure the target router into the network. In a network, a system operator monitors a network for undesirable message traffic. Upon a notification of such undesirable message traffic, traffic is rerouted to a filter complex to separate undesirable traffic. The filter complex establishes an alternate route using a second communications protocol, and uses the alternate route to redirect the desirable message traffic to the target node. The use of the second protocol avoids conflict between the redirected desirable traffic and the original, or first, protocol which now performs the reroute. In this manner, the filter complex employs a second alternate communications protocol to reroute and redirect desirable message traffic to the target node while diverting undesirable message traffic, and therefore avoids widespread routing configuration changes by limiting the propagation breadth of the second protocol.

GNSS based control for dispensing material from vehicle

A spray control method employs a spray vehicle including a material tank, a pump communicating with the tank, and nozzles of a spray boom communicating with the pump. A GNSS receiver mounted on the vehicle and interfaced to a controller tracks its position in relation to stored position coordinates of field boundaries separating spray zones from spray exclusion zones. The tank is activated and deactivated by the controller to retain spray of the material within the spray zones and to prevent spray of the material in the exclusion zones, by processing an offset of the spray nozzles from the receiver, the spray range of the nozzles, spray turn-on and turn-off lag times, and the velocity of the spray vehicle, all in relation to the field boundaries. An alternative embodiment individually controls spray from the nozzles by using associated valves interfaced to the controller.

Modified release compositions of milnacipran

A once-a-day oral milnacipran modified release formulation has been developed. The formulation comprises an extended release dosage unit (optionally containing the immediate release portion) coated with delayed release coating. The milnacipran composition, when administered orally, first passes through the stomach releasing from zero to less than 10% of the total milnacipran dose and then enters the intestines where drug is released slowly over an extended period of time. The release profile is characterized by a 0.05-4 hours lag time period during which less than 10% of the total milnacipran dose is released followed by a slow or extended release of the remaining drug over a defined period of time. The composition provides in vivo drug plasma levels characterized by Tmax at 4-10 hours and an approximately linear drop-off thereafter and Cmax below 3000 ng / ml, preferably below 2000 ng / ml, and most preferably below 1000 ng / ml. The composition allows milnacipran to be delivered over approximately 24 hours, when administered to a patient in need, resulting in diminished incidence or decreased intensity of common milnacipran side effects such as sleep disturbance, nausea, vomiting, headache, tremulousness, anxiety, panic attacks, palpitations, urinary retention, orthostatic hypotension, diaphoresis, chest pain, rash, weight gain, back pain, constipation, vertigo, increased sweating, agitation, hot flushes, tremors, fatigue, somnolence, dyspepsia, dysoria, nervousness, dry mouth, abdominal pain, irritability, and insomnia.

Timed pulsatile drug delivery systems

A pharmaceutical dosage form such as a capsule capable of delivering therapeutic agents into the body in a time-controlled or position-controlled pulsatile release fashion, is composed of a multitude of multicoated particulates (beads, pellets, granules, etc.) made of one or more populations of beads. Each of these beads except an immediate release bead has at least two coated membrane barriers. One of the membrane barriers is composed of an enteric polymer while the second membrane barrier is composed of a mixture of water insoluble polymer and an enteric polymer. The composition and the thickness of the polymeric membrane barriers determine the lag time and duration of drug release from each of the bead populations. Optionally, an organic acid containing intermediate membrane may be applied for further modifying the lag time and / or the duration of drug release. The pulsatile delivery may comprise one or more pulses to provide a plasma concentration-time profile for a therapeutic agent, predicted based on both its pharmaco-kinetic and pharmaco-dynamic considerations and in vitro / in vivo correlations.

Control methods for low emission internal combustion system

Improved transient response times are obtained while maintaining low emissions with a low pressure EGR system through methods for quickly obtaining a desired oxygen concentration for charge-air to be used for combustion. Under a first method, fuel quantity in the main combustion event is controlled in the combustion process to produce exhaust around a relatively constant target exhaust oxygen concentration value. By keeping the exhaust oxygen concentration levels at a relatively constant value, lag time in waiting for low pressure EGR valve adjustments during transients may be avoided, and the system's air handling response to meet transients may be paced solely by adjusting the mass of air to be supplied (i.e. boost response). Under a second method, a multiple-stage combustion process is utilized, in which fuel feed is controlled in a small, preliminary HCCI-type combustion event in order to produce a target oxygen concentration of charge-air to be used for the second, main combustion event. Under a third method, exhaust rebreathing is used to produce a target oxygen concentration of charge-air to be used for combustion.

Migration Velocity Analysis of Seismic Data Using Common Image Cube and Green's Functions

Seismic data are assembled and stored for a set of cross-correlation lag times to form an array of common image gathers over depth levels of interest. The two dimensional gathers assembled over different lag times form a three-dimensional cube of common image data. The data are analyzed to determine the travel time shift required to equalize upgoing and downgoing wavefields. Events in the common image gathers are then modeled using Green's functions to generate a data set representing the data resulting from processing had a precise velocity model been obtainable from the seismic data. The generated data are then processed with inversion techniques to form a velocity model for seismic data analysis.
