Abstract: The invention provides a strategy to start a parallel HEV powertrain engine while maintaining a smooth vehicle response to driver demand using the motor while simultaneously closing an engine disconnect clutch. In the preferred embodiment, the strategy starts an engine (based on, for example, driver demand), closes the disconnect clutch, commands a desired motor/generator speed, fuels the engine, calculates a desired engine torque and gradually reduces actual motor/generator torque while proportionally increasing actual engine torque until motor/generator torque is zero while maintaining vehicle velocity using, for example, a proportional plus integral controller. The prediction of a desired motor/generator speed can be: a trajectory comparison based on present and past vehicle velocity and acceleration or on vehicle accelerator position, or a determination of whether the vehicle is in speed control mode.

Abstract: The present invention provides a control strategy for a parallel hybrid electric vehicle (HEV) configuration where power from the engine and the motor can each independently provide torque to the vehicle powertrain. The invention has a logical structure defining main system operating modes (states) and the transition between the different states. In addition to the predefined states, the present invention provides a set of rules defining logical relationships between each of the plurality of predefined states and a set of commands unique to each state. These commands are supplied to subsystem controllers to achieve desired vehicle functionality. The predefined states can be prioritized according to operator demands, energy management requirements, and system fault occurrences. The present invention can also be configured to have at least one of a plurality of transition flags.

Abstract: The invention provides a strategy to stop a parallel HEV powertrain engine while maintaining smooth vehicle response to driver demand using the motor while simultaneously opening an engine disconnect clutch. In the preferred embodiment, the strategy stops an engine (based on, for example, driver demand), disconnects the disconnect clutch to the powertrain, halts fuel to the engine, and predicts a desired motor/generator speed. The prediction of desired motor/generator speed can be: a trajectory comparison based on present and past vehicle velocity and deceleration or on a vehicle accelerator position, or a determination of whether the vehicle is in speed following control mode. The system can also add additional strategies such as accelerate the strategy if a vehicle brake is applied. The gradual takeover by the motor occurs by proportionally decreasing actual engine torque until engine torque is zero while maintaining vehicle velocity using for example a proportional plus integral controller.

Abstract: A regenerative brake control method and system for a hybrid electric vehicle (HEV) with a disconnect clutch separating the engine from the motor. When the engine is disconnected from the HEV powertrain, more regenerative braking energy is possible because the negative powertrain torque of the engine's friction and pumping is eliminated. The control can determine when to disconnect and reconnect the engine to the powertrain using, for example, driver demand, vehicle speed, accelerator position, brake pedal position, engine state, motor state, and motor fault status. The control also minimizes powertrain disturbance to improve vehicle drivability by continuously adjusting the amount of regenerative braking to correspond to the changing torque of the engine on the powertrain during disconnect or reconnect.

Abstract: A system and method are provided for automatically generating a summary document with information mined from a data repository. The database stores information garnered from a plurality of sources. The information includes the type of data which can be easily organized into fields, as well as less definable data such as transcribed dictation. The information is converted into a markup language for parsing and storage as tagged data and marked up data objects. The summary document is created from the tagged and marked up data objects. Specific examples are also provided for the generation of a clinical resume type summary document.

Abstract: An energy control strategy (10) for a hybrid electric vehicle that controls an electric motor during bleed and charge modes of operation. The control strategy (10) establishes (12) a value of the power level at which the battery is to be charged. The power level is used to calculate (14) the torque to be commanded to the electric motor. The strategy (10) of the present invention identifies a transition region (22) for the electric motor's operation that is bounded by upper and lower speed limits. According to the present invention, the desired torque is calculated by applying equations to the regions before, during and after the transition region (22), the equations being a function of the power level and the predetermined limits and boundaries.

Abstract: A method of functionalizing a diamond crystal comprises hydrogenating a diamond crystal, chlorinating the hydrogenated diamond crystal; and exposing the chlorinated diamond crystal to a metal precursor. The exposing step deposits a layer of metal on surfaces of the diamond crystals. The diamond crystal formed by the method possesses surface sites that form a strong bond with the layer of metal to prevent separation thereat, and the layer of metal form strong bonds to a matrix material, for example one of a vitreous and metallic matrix. The functionalized diamond crystal can be used in abrasive products.

Abstract: During debugging of target system by a host system, s single stack is used for an exception by a set of applications running on the processor of the target. To achieve this, the stack is dynamically loaded by the host to a reserved memory region, and a vector of the target is set to point to that reserved memory region. The exception handlers of each application then use the vector to access the stack.

Abstract: A vehicle system controller (20) is presented for a LSR parallel hybrid electric vehicle having an engine (10), a motor (12), wheels (14), a transmission (16) and a battery (18). The vehicle system controller (20) has a state machine having a plurality of predefined states (22-32) that represent operating modes for the vehicle. A set of rules is defined for controlling the transition between any two states in the state machine. The states (22-32) are prioritized according to driver demands, energy management concerns and system fault occurrences. The vehicle system controller (20) controls the transitions from a lower priority state to a higher priority state based on the set of rules. In addition, the vehicle system controller (20) will control a transition to a lower state from a higher state when the conditions no longer warrant staying in the current state. A unique set of output commands is defined for each state for the purpose of controlling lower level subsystem controllers.

Abstract: A host computer has a file with a subroutine required for operation of an application on a target. The file is dynamically loaded to memory of the target, whereby the file has an entry point at a dynamically-determined location. Data representative of the address of the entry point is stored in memory at a predetermined location.

Abstract: To enable a processor connected to a host computer to run programs that are dynamically loaded by the host, a stack is loaded into its memory, and the location of the stack, or information enabling that location to be found are stored in a memory location reserved as a vector. The programs are then dynamically loaded into said memory; and a set location in the stack is used to store the entry point into the dynamically loaded file.

Abstract: A register of a processor is set to one value when a host is connected to the processor and to a second value when no host is connected. The processor then starts execution after reading the register contents, and if it finds that the second value is stored it writes a set value to a pointer storage location. When the one value is stored, it leaves the content of the pointer location unaffected.

Abstract: An application program runs on an embedded processor connected via a link to a host. When the application program identifies a need for communication over said link, it reads a pointer location to see whether its contents represent a valid address in memory, and if so the program calls that address. It then checks the code at the address to see whether an entry point is stored there, and if so uses that entry point to access a subroutine enabling communication over the link.
