  • Publication number: 20090241899
    Abstract: A reserve torque system comprises a first module and a reserve torque module. The first module generates a first signal a predetermined period before an equivalence ratio (EQR) of an air/fuel mixture supplied to an engine is transitioned from a non-lean EQR to a lean EQR. The reserve torque module creates a reserve torque between when the first signal is generated and when the EQR is transitioned to the lean EQR.

  • Publication number: 20090204280
    Abstract: A hybrid controller for controlling a hybrid vehicle is set forth. The hybrid vehicle has an engine, an electric motor and an engine controller determining a crankshaft torque. The hybrid controller includes an optimization module determining an electric motor torque, determining an engine torque and communicating the engine torque from the hybrid controller to the engine controller. The hybrid controller also includes a motor control module controlling the electric motor based on the electric motor torque.

  • Patent number: 7357019
    Abstract: A diagnostic system that detects a faulty lifter oil manifold assembly solenoid includes a current measurement module, a time delay module, a voltage measurement module, and a diagnostic module. The current measurement module measures current flowing through the solenoid when a trigger signal is enabled. The time delay module determines a time delay based on the measured current. The voltage measurement module measures a supply voltage that powers the solenoid. The diagnostic module determines whether the solenoid is faulty based on the time delay and supply voltage.

  • Publication number: 20060074844
    Abstract: An improved method and system are provided for creating tasks and for inputting information associated with created tasks according to an electronic task management application or system. Electronic correspondence items may be flagged as tasks. Upon flagging an individual electronic correspondence item, a corresponding task is created for the flagged item, and the created task is then populated into and exposed by one or more applications used for displaying tasks such as a tasks application, calendar application, or electronic to-do list application. Properties such as task start dates and task categories may be applied to the created task, as desired.

  • Publication number: 20060069603
    Abstract: An improved user interface is provided for allowing the application of two properties or pieces of metadata to an object with a single user action. A two-dimensional radial menu (user interface) is provided. The radial menu is a generally pie-shaped user interface that is divided into two or more slices associated with two or more corresponding types of a first property that may be applied to a selected object. The menu is further divided to two or more circular sections so that each slice of the pie-shaped radial menu is further divided into two or more sections. Each circular section is associated with a type of a second property that may be applied to the object. By selection of a given section in a given slice of the radial menu, one type of the first property associated with the given slice and a one type of the second property associated with the given circular section of the slice are applied to the selected object with a single user action.

  • Publication number: 20060069604
    Abstract: An electronic “To-Do” bar is provided in which displayed upcoming tasks, meetings, appointments and the like. The electronic To-Do bar is displayed in a lightweight menu of tasks, meetings and appointments and is displayed persistently in addition to other software functionality or user interfaces displayed on a user's computer display screen according to other software applications or other software functionality in use. A user is presented with an always-visible list of upcoming tasks, meetings and appointments without the need to launch a separate tasks application or calendar application to view upcoming tasks, meetings or appointments.

  • Patent number: 7002352
    Abstract: A diagnostic apparatus is suitable for use in an automobile controller and includes a power supply terminal conducting a reference voltage, a sampling circuit and a reference voltage diagnostic circuit. The sampling circuit is coupled to the power supply terminal and has an output terminal for providing sampled values of the reference voltage. The reference voltage diagnostic circuit has an input terminal coupled to the output terminal of the sampling circuit. The reference voltage diagnostic circuit maintains a historical value of the reference voltage over a predetermined time period, compares a current sampled value of the reference voltage to the historical value, and indicates a fault in the reference voltage in response to the current sampled value being different from the historical value by more than a predetermined threshold.
