20120197500 | SYSTEM AND METHOD OF SPEED-BASED DOWNSPEED COASTING MANAGEMENT - A velocity profile can be used in conjunction with vehicle operating condition data to determine a gear shift schedule that mitigates the amount of service brake effort required to slow a vehicle by making optimal use of engine speed, friction and engine brakes. The gear shift point drives the engine to a higher operating speed and greater frictional torque, slowing the vehicle, which can then coast to a desired speed. The gear shift point can be timed to minimize fuel consumption during the maneuver. Thus, a vehicle downshift event is created based on the transmission gear recommendation. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability. | 08-02-2012 |
20120197501 | SYSTEM AND METHOD OF VEHICLE OPERATING CONDITION MANAGEMENT - A vehicle operating condition profile can be determined over a given route while also considering imposed constraints such as deviation from time targets, deviation from maximum governed speed limits, etc. Given current vehicle speed, engine state and transmission state, the present disclosure optimally manages the engine map and transmission to provide a recommended vehicle operating condition that optimizes fuel consumption in transitioning from one vehicle state to a target state. Exemplary embodiments provide for offline and online optimizations relative to fuel consumption. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability. | 08-02-2012 |

In one representative embodiment, the expected temperature change of the engine component at a later time is determined based on inefficient operation of the engine, such as a transmission down shift resulting in higher engine speed and lower engine torque, and the expected temperature change of the engine component resulting from operating the engine under current conditions or expected conditions at that later time is determined.

20120221234 | SYSTEM AND METHOD OF VEHICLE FUEL QUANTITY MANAGEMENT - Systems and methods of vehicle fuel quantity management are provided to assist in determining an optimal quantity of fuel to carry on-board a vehicle. Certain routes are sufficiently short so to not require a completely filled fuel tank to traverse. Additionally, most routes have an abundance of vehicle fueling stations that provide ample refueling opportunities, thus permitting an operator to carry less fuel than might be required to complete a route. Exemplary embodiments of the present disclosure balance initial fuel loading and fuel stops to optimize the amount of freight weight that can be carried for a given route. The benefit is increased freight efficiency in transporting cargo from source to destination while maintaining drivability. | 08-30-2012 |
20120239588 | SYSTEM AND METHOD OF DETERMINING FREIGHT/LOAD DISTRIBUTION FOR MULTIPLE VEHICLES - Systems and methods of vehicle freight/load distribution are provided to assist in determining optimal freight distribution. Although it is standard practice to fill each vehicle to its maximum limit, due to the non-linear nature of engine fueling maps (that is, fueling maps vary non-linearly as a function of torque and speed), the optimal distribution may not be obtained by the standard practice. Finding a solution for the optimal freight distribution may also need to account for the cost of fueling and operator costs, particularly if the situation involves multiple vehicles not filled to capacity. The benefit is increased freight efficiency in transporting cargo from source to destination amongst a fleet of vehicles. | 09-20-2012 |

20080313737 | Stateful and Cross-Protocol Intrusion Detection for Voice Over IP - A method for detecting intrusions that employ messages of two or more protocols is disclosed. Such intrusions might occur in Voice over Internet Protocol (VoIP) systems, as well as in systems in which two or more protocols support some service other than VoIP. In the illustrative embodiment of the present invention, a stateful intrusion-detection system is capable of employing rules that have cross-protocol pre-conditions. The illustrative embodiment can use such rules to recognize a variety of VoIP-based intrusion attempts, such as call hijacking, BYE attacks, etc. In addition, the illustrative embodiment is capable of using such rules to recognize other kinds of intrusion attempts in which two or more protocols support a service other than VoIP. The illustrative embodiment also comprises a stateful firewall that is capable of employing rules with cross-protocol pre-conditions. | 12-18-2008 |
20090070874 | Signature-Free Intrusion Detection - An apparatus and method are disclosed for detecting intrusions in Voice over Internet Protocol systems, without the use of an attack signature database. In particular, the illustrative embodiment is based on the observation that some VoIP-related protocols (e.g., the Session Initiation Protocol [SIP], etc.) are simple enough to be represented by a finite-state machine (FSM) of compact size. A finite-state machine is maintained for each session/node/protocol combination, and any illegal state or state transition—which might be the result of a malicious attack—is flagged as a potential intrusion. | 03-12-2009 |
20090070875 | Distributed Stateful Intrusion Detection for Voice Over IP - An apparatus and method are disclosed for detecting intrusions in Voice over Internet Protocol systems without an attack signature database. The illustrative embodiment is based on two observations: (1) various VoIP-related protocols are simple enough to be represented by a finite-state machine (FSM) of compact size, thereby avoiding the disadvantages inherent in signature-based intrusion-detection systems.; and (2) there exist intrusions that might not be detectable locally by the individual finite-state machines (FSMs) but that can be detected with a global (or distributed) view of all the FSMs. The illustrative embodiment maintains a FSM for each session/node/protocol combination representing the allowed (or “legal”) states and state transitions for the protocol at that node in that session, as well as a “global” FSM for the entire session that enforces constraints on the individual FSMs and is capable of detecting intrusions that elude the individual FSMs. | 03-12-2009 |
20090274143 | State Machine Profiling for Voice Over IP Calls - An apparatus and method for detecting potentially-improper call behavior (e.g., SPIT, etc.) are disclosed. The illustrative embodiment of the present invention is based on finite-state machines (FSMs) that represent the legal states and state transitions of a communications protocol at a node during a Voice over Internet Protocol (VoIP) call. In accordance with the illustrative embodiment, a library of FSM execution profiles associated with improper call behavior is maintained. When there is a match between the behavior of a finite-state machine during a call and an execution profile in the library, an alert is generated. | 11-05-2009 |
20090274144 | Multi-Node and Multi-Call State Machine Profiling for Detecting SPIT - An apparatus and method for detecting potentially-improper call behavior (e.g., SPIT, etc.) are disclosed. The illustrative embodiment of the present invention is based on finite-state machines (FSMs) that represent the legal states and state transitions of communications protocols at nodes during Voice over Internet Protocol (VoIP) calls. In accordance with the illustrative embodiment, a library of FSM execution profiles associated with improper call behavior and a set of rules (or rule base) associated with improper FSM behavior over one or more calls are maintained. When the behavior of one or more finite-state machines during one or more calls matches either an execution profile in the library or a rule in the rule base, an alert is generated. | 11-05-2009 |
20100278325 | Annoying Telephone-Call Prediction and Prevention - A method for predicting whether a telephone call that is being set up will be considered annoying by the called party and, if so, for preventing it from being established. The illustrative embodiment predicts whether a telephone call will be considered annoying by the called party based on temporal characteristics of previous calls from the same caller. For example, when a called party receives an unwanted telephone solicitation, he or she will usually hang up within the first minute. If many telephone calls are made from the same caller, and all of these calls last under a minute, then it is reasonable to predict that future calls from this caller will be considered annoying. | 11-04-2010 |
