Aspects of the invention provide virtual hover zones. When a user lowers a hovering stylus while remaining within a hover zone, cursor control is modified to be more easily controllable by the user. If the user pauses the stylus in mid-air before lowering the stylus, and if the stylus remains within the hover zone, then upon touchdown the cursor may be moved to the projection of the location where the stylus was paused. Any action that my be taken in response to the touch down may be sent to the projection location as well. Also provided are cursor control zones. A dampening zone may be used to provide dampened cursor movement feedback in response to movement input provided by a pointing device. Also, a dead zone may be used to prohibit cursor movement in response to movement input provided by the pointing device.

A method is disclosed for controlling operation of an engine coupled to an exhaust treatment catalyst. Under predetermined conditions, the method operates an engine with a first group of cylinders combusting a lean air / fuel mixture and a second group of cylinders pumping air only (i.e., without fuel injection). In addition, the engine control method also provides the following features in combination with the above-described split air / lean mode: idle speed control, sensor diagnostics, air / fuel ratio control, adaptive learning, fuel vapor purging, catalyst temperature estimation, default operation, and exhaust gas and emission control device temperature control. In addition, the engine control method also changes to combusting in all cylinders under preselected operating conditions such as fuel vapor purging, manifold vacuum control, and purging of stored oxidants in an emission control device.

The present invention is a dual-stage fuel injection strategy for compression ignition engines in which 15-40% of the fuel is injected into the combustion chamber no later than about −20 to −30 CA ATDC and as early as IVC. The rest of the fuel is then injected in one or more fuel pulses, none of which start before about −20 to −30 CA ATDC. The fuel injected early in the compression stroke forms a lean mixture that burns with low soot and low NOx emissions. The combustion of that fuel serves to increase in-cylinder temperature such that the ignition delay of subsequent fuel injection pulses is short. This mode is utilized when it is predicted that a NOx spike is imminent. Various other alternative methods for reducing NOx spikes are also disclosed such as specialized EGR systems that can provide EGR with low manifold vacuum.

From these measurements, an absorbance or transmittance is determined (40) from which the concentrations of hydrogen peroxide and water vapor are determined (42). Monitored temperature (44) and the determined concentrations are converted into a percent saturation (54). The supply of hydrogen peroxide and water vapor to the chamber is controlled (60) in accordance with the determined percent saturation.

A method and an apparatus for controlling a privacy mask display includes a monitoring camera which is if tilted and its tilt angle becomes greater than 90° when a privacy mask to mask a specific target object in a captured image frame is displayed, an image and the privacy mask in the frame are rotated 180° with respect to the CCD center axis, and the optical center axis stored in the apparatus is also rotated 180° with respect to the CCD center axis. Afterwards, if the zoom ratio of the monitoring camera changes, the size and position of the privacy mask are adjusted relative to the optical center axis rotated 180° with respect to the CCD center axis. It is therefore possible to freely perform zooming and tilting operations without danger of exposing the privacy-protected target object even under the condition that the optical center axis and the CCD center axis of the monitoring camera do not coincide.

To control load / unload operation of a slider with magnetic head mounted thereon, by which the speed can always be controlled stably while avoiding the slowdown or temporary stop of an actuator during load / unload operation, a magnetic disk drive is configured using magnetic disk media with the servo information written therein beforehand up to the track located at a position corresponding to the landing zone for the load operation of the magnetic head (slider). The speed of the magnetic head (slider) withdrawn to the ramp is controlled at the unload operation. In the stage of initialization for controlling the speed of the load / unload operation, various parameters are recorded and updated to apply a voltage to power amplifier for compensating for the external forces caused by the friction mainly exerted between ramp and slider support members, with reference to the take-off track or the landing track specified in the landing zone.

A battery charge / discharge control apparatus for a vehicle capable of driving an electric motor by a battery is provided. Temperature of the battery is detected, temperature history distribution of the battery after start of temperature detection is calculated, and a lifetime workload of the battery is calculated on the basis of this temperature history distribution of the battery. A permissible value of a workload increase rate indicating a workload to increase per unit distance is calculated on the basis of the lifetime workload of the battery and a travel distance of the vehicle. An actual workload increase rate of the battery is compared with the permissible value of the workload increase rate. In the case where the actual workload increase rate is larger than the permissible value of the workload increase rate, an output is restricted from the output of the battery restricted in a normal driving mode if necessary by a restricted value based upon a difference between the actual workload increase rate and the permissible value of the workload increase rate. This makes it possible to carry out lifetime prolonging control for the battery more accurately by setting up an appropriate charge / discharge permissible amount in accordance with temperature change of the battery in the past.

PCT No. PCT / NZ95 / 00065 Sec. 371 Date Jan. 3, 1997 Sec. 102(e) Date Jan. 3, 1997 PCT Filed Jul. 21, 1995 PCT Pub. No. WO96 / 03304 PCT Pub. Date Feb. 8, 1996A wheeled transporter for air cargo includes a load carrying platform having rollers, connected at one edge to a power console incorporating a prime mover, and supported at the other edge with unpowered castoring wheels. The transporter is driven by two steerable wheels located beneath the console adjacent opposite ends. Each steerable wheel is driven by a reversible motor, and is steerable so that when one wheel is turned in one direction the other is turned in an opposite direction. The transporter can thus be driven in either direction along path (X), and turned or rotated on (Z). By turning the wheels through 90 degrees to the longitudinal direction, the transporter can be driven along a path (Y) in either direction, and steered by varying the differential speed of the wheels. A container carried on the deck can be moved and rotated in directions X', Y' and Z'.

The control precision of one or more parameters of an integrated circuit (IC), for example the output voltage of a voltage regulator comprised in the IC, may be improved even when using inaccurate components external to the IC. Control of the output voltage, or any parameter, using components external to the IC may include coupling a resistor to the IC and measuring the actual resistance value of the resistor, and based on the measured value, selecting a nominal resistance value from a set of resistance values previously specified by the user. The output voltage, or parameter, may be generated according to the nominal resistance value instead of the actual resistance value, thereby reducing the error that may be incurred due the actual resistance value of the resistor not matching the expected nominal value of the resistor. The difference between each adjacent resistance value in the set of resistance values may be selected to be greater than the greatest measurement error that may be incurred during measuring the actual resistance value.

In a second state, a reverse current is conducted through the bi-directional switching circuit from the DC or AC output voltage to the output electrode to discharge the DC or AC output voltage and return power to the primary section of the piezoelectric transformer.

The invention is directed to a method for controlling delays in a cellular telecommunications network. The delay control method according to the invention is based on a hierarchical structure of delay controlling entities, which preferably communicate only with entities directly above or below them in the hierarchy. In the downlink direction, an entity receiving data, such as a base station or a splitting unit, sends a timing report to the entity sending the data if the data is received too early or too late, whereafter the sending entity may adjust the sending time of data. The same reporting and adjusting process may be repeated through all levels of the control hierarchy, resulting in a collective control of delays from the top of the hierarchy, for example from a RNC, to the bottom, for example to a base station. In the uplink direction, a higher level entity receiving data from a lower level entity may command the lower level entity to adjust the sending time, if the data is received too early or too late. When the same action is repeated in all levels of the hierarchy, a collective control of delays is achieved for the link between the lowest level, e.g. the base station, and the highest level, e.g. a RNC.
