A method is provided for optimizing the cycling frequency between engine on/off states in a vehicle having a controller and auto start/auto stop functionality. The method includes detecting an engine state cycling event, measuring a plurality of vehicle operating values, and using the controller to optimize the cycling frequency via at least one of: automatically adjusting an interval between an auto start event and an auto stop event when each of a first set of the vehicle operating values exceeds a corresponding threshold, and temporarily inhibiting the auto start/auto stop functionality when any value in a second set of the vehicle operating values falls outside of a hysteresis band created around the second set. A vehicle includes an engine and a controller having an algorithm for optimizing the cycling frequency between engine on/off states as set forth above.

A gas desulfurization scrubbing system for removing sulfur oxides from gases, such as those of fossil fuel burning operations or other manufacturing process emitting sulfur oxides, and for collecting reaction products of the desulfurization chemical reactions. A quenching section is disposed in a gas duct upstream of a gas desulfurization scrubbing tower and a scrubbing slurry is provided at that section for quenching and chemically reacting with the gas. A quench reaction product is collected, at a location between the quenching section and the scrubbing tower, for use in making commercial by-products, such as gypsum.

A display screen magnifier is controllable by a user to magnify selected portions of a desktop including windows open on the screen. A moveable magnifier frame is provided, within which a magnified image is presented. The magnified image corresponds to screen content located within a magnification region underlying the magnifier frame, magnified to a set level of magnification. The magnifier is controllable through use of a user input device. At least one operational parameter of the magnifier can be adjusted, without interaction with on-screen objects and without taking focus away from the desktop or any windows open on the screen. In a particular embodiment of the invention, on-the-fly controllability of the magnifier includes its activation and deactivation, adjustment of the magnification level, and adjustment of the size of the magnifier frame.

A system, method and computer program product for verifying an avatar owner as a human user of an avatar in a virtual world environment in which users may interact through avatars, representing each one or more users visually, and wherein users, interact through their the representing avatars, via client devices in network communication with a server device. The method includes receiving a request for challenging an avatar in the virtual world environment to determine whether that avatar is controlled by an application program user (bot). Then, in response to the challenging, a user client device associated with a challenged avatar is identified and a HIP message for detecting a human user versus a bot controlling the challenged avatar is generated and communicated, for receipt at a user client device. The HIP message requires an response from the corresponding user. It is determined from the response, whether the user is a bot or a human user. If a challenged avatar is determined to be a bot, then the server device prevents the challenged avatar from further interaction in the virtual world environment.
摘要:
An improved register allocator is provided to the code generator of a compiler. The improved register allocator allocates registers using an improved register candidate usage matrix. The improved register candidate usage matrix comprises row entries, one for each register candidate. Each row entry comprises usage bits indicating at least whether its register candidate is live at the entries, in the bodies, and at the exits of the various basic blocks. The improved register allocator allocates registers by block, deriving interference information from the improved usage matrix. It then merges the register allocation introducing spill code at points where register candidates are split. As a result, a register can be allocated to two register candidates that are live in the same basic block as long as they are not both live at some point in the basic block, and at the same time, a register candidate can be spilled in one basic block and allocated a register in another basic block.

An improvement in the process for the oxidative coupling of methane is provided. Typically, the reaction takes place in a reactor that includes a catalyst zone. A primary CH.sub.4 /O.sub.2 stream is fed into the entrance of the reactor and reacted at a temperature of 600.degree. C.-1000.degree. C. and a pressure of between 101 kPa and 800 kPa. The improvement comprises introducing an auxiliary oxygen stream directly into the catalyst zone and one or more points to thereby selectively increase the yield of C.sub.2+ products.

A method for starting an internal combustion engine in a hybrid powertrain having an electric torque machine mechanically coupled to the internal combustion engine includes monitoring a temperature state of the hybrid powertrain, determining a maximum discharging power limit of the high-voltage battery corresponding to the temperature state of the hybrid powertrain, estimating an engine drag torque associated with the temperature state of the hybrid powertrain, selecting a preferred engine cranking speed associated with the estimated engine drag torque and achievable at less than the maximum discharging power limit of the high-voltage battery, and controlling the electric torque machine to generate a magnitude of motor torque output sufficient to crank the internal combustion engine at the preferred engine cranking speed.

A method for controlling a hybrid powertrain system includes commanding engine operation to transition from an engine-off state to an engine-on state. A control scheme detects engine firing based upon input speed, input torque and a change in the input torque.
摘要:
A device may generate a media stream to be shared with other users by building a media graph, comprising a series of interconnected processing units that perform various processing tasks. However, the time involved in generating the media graph may delay the initialization of the media stream, and adjusting properties of the media stream (such as resolution or codec) may result in an interruption of the media stream while a new media graph is built. Instead, a media graph cache may be provided to cache a set of media graphs, which may be interchangeably selected for rapid initialization and adjusting of media stream properties. The media component (e.g., a video camera) may also be configured to promote rapid adjustments to some media stream properties, while maintaining other properties (e.g., field of view and white balance) for a smooth transition between media stream property sets.

A display screen magnifier is controllable by a user to magnify selected portions of a desktop including windows open on the screen. A moveable magnifier frame is provided, within which a magnified image is presented. The magnified image corresponds to screen content located within a magnification region underlying the magnifier frame, magnified to a set level of magnification. In one embodiment, the magnification region is moveable relative to the magnifier frame, in relation to movement of the magnifier frame on the display screen. Such relative movement can be used to avoid a potentially disorienting edge condition that arises when a magnifier frame reaches an edge of the display screen and stops, while its associated magnification region continues to pan. In another embodiment, the cursor of a user input device is moveable across the screen display into and out of the magnification region. When the position of the cursor falls within the magnification region, the cursor appears within the magnified image presented within the magnifier frame. A related feature avoids the potentially disconcerting effect of cursor disappearance as a pointing device cursor passes into a “lens shadow” defined between the magnification region and the magnifier frame.
