A “Charting Animator” enhances computer-based charting/graphing systems by rendering dynamic animations of chart displays. In general, when a user changes from one chart type to another, adds new data to a chart, or changes, sorts or deletes data, a new chart is generated to replace the old chart. Conventional charting systems simply replace the existing chart with the new chart. In contrast to conventional systems, the Charting Animator renders animated transitions that dynamically morph the original chart into the new chart. Consequently, these animations avoid abrupt changes that can disorient users. Examples of these animations include animating changes from one chart family to another (e.g., changing from a “Bar Chart” to a “Pie Chart”), animating changes from one chart type within a chart family to another chart type (e.g., changing 2D Bar Charts to 3D Bar Charts or Stacked Bar Charts), animating data changes, animating sorts, etc.

The invention relates to a method for compensating for drive influences of a drive train of a motor vehicle on its steering system, said motor vehicle having an electric power steering system. A drive train simulation model which is integrated into the motor vehicle and permanently activated is used to determine disturbance variables from a driven behavior so that a compensation torque which counteracts the disturbance variables is generated for the power steering system.

A display apparatus including: a display configured to display an image; and at least one processor configured to, in response to beginning a viewer fatigue reduction function, determine whether a change characteristic of an image displayed on the display during a first time interval of an image signal corresponds to a suitable section for the viewer fatigue reduction function, and control the display to decrease a viewing fatigue level of the displayed image during the determined suitable section.

Method and system for synchronization of base stations in a mobile communications network, in particular for the purpose of a seamless handover, time information is transmitted, possibly on request, to the base stations from a time information server via a local area network. Since base stations which are involved in a seamless handover are generally adjacent, and the respective propagation times and/or propagation time fluctuations of time information differ only slightly in the local area network between the time information server and the base station when the base stations are adjacent, highly accurate synchronization may be achieved, especially for a seamless handover.

This arrangement of the invention makes intuitively comprehensible image correction of RGB color image data after conversion to HSI data in an intuitive HSI expression format, while ensuring no substantial change of the picture quality of a resulting color image by correction.

The technique of the invention analyzes an image consisting of sampling HSI data with regard to each of multiple memory colors, that is, flesh color, green, and sky blue, and sets color correction areas as object correction ranges and correction rate curves in the color correction areas in respective hue ranges of the multiple memory colors, based on the results of the image analysis. These settings are given in the form of a correction table. A correction rate curve set for, for example, the hue range of flesh color in the correction table corrects original hue data Horg of HSI data converted from RGB color image data with a fixed correction rate Δ h in a substantial color correction zone SkH2 to SkH3, while correcting the original hue data Horg of the HSI data with varying correction rates Δ h in a pre-zone SkH1 to SkH2 and in a post-zone SkH3 to SkH4 before and after the substantial color correction zone SkH2 to SkH3 in a preset color correction area SkH1 to SkH4. The correction rate curve does not make any correction for the original hue data Horg of the HSI data out of the preset color correction area SkH1 to SkH4.

To synchronize communications system components coupled via a communications network, a time information transmitter is provided which is used to transmit time information, possibly on request, relating to the communications system components. The communications system components each have a clock generator, which needs to be synchronized, and a real time clock, where the clock generator both determines the transmission rate for communications data which are to be transmitted and prescribes the time base for the real time clock. In addition, the communications system components each have a comparison device for comparing received time information with a current time value indicated by the real time clock, and a clock frequency controller for regulating the clock frequency of the clock generator on the basis of the comparison result.

A camera device includes an imaging unit generating an imaging area image in which an imaging area is captured from above, and a display-image generation unit generating a display image of an imaging object moving in the imaging area by use of an clipped image clipped from the imaging area image. In this case, an clipping reference position P corresponding to the imaging object in the imaging area image is determined, and a reference distance r between an imaging reference position O corresponding to the imaging unit and the clipping reference position P in the imaging area image is calculated. When the reference distance r is short, a rotation angle θ_NEW for rotating the clipped image in generating the display image is calculated based on a reference angle θ corresponding to an inclination of the imaging object in the imaging area image and the reference distance r.

The number of graphic objects in a visual tile rendered varies as a function of distance between the tile and a viewpoint in a simulation. Fewer objects are rendered when the tile is far from the viewpoint, and vise versa. A level of detail (LOD) value is pseudo-randomly selected and associated with each object, indicating the maximum distance at which the object will be visible. A current LOD value is determined for the tile. An object is rendered if its LOD value is equal or greater than the current LOD value of the tile. Objects are faded into and out of view by modulating an opacity value as the current LOD value changes. Texture values of an object are adjusted as a function of ambient and direct components of light on the object, to achieve lighting corresponding to time of day, current season, and/or region in the simulated world.

Frames in a variable length frame format which are addressed to a plurality of users are multiplexed and preferably transmitted.

Data frames having different lengths are multiplexed on a same time through space division multiple access, but since the multiplexed frames are transmitted while eventually having a same length, when the multiplexed data frames from the access point STA0 are received in the respective communication stations STA1 to STA3 in FIG. 4 or when data simultaneously transmitted from the respective communication stations STA1 to STA3 are received in the access point STA0 in FIG. 5, it is possible to eliminate an operation instability of AGC.

A control apparatus for a vehicle electric generator judges the currently available generating capacity of the generator and establishes a regenerative current mode of operation, utilizing an induced current of the field winding, only when the generating capacity is estimated to be below a predetermined level. The control apparatus also controls the conduction factor of a power transistor to adjust the average voltage applied to the field winding such as to prevent fluctuations in output current and generator torque that would otherwise occur at each changeover to/from the regenerative current mode.

A phase-locked loop with a non-integer divider utilizes a state machine to periodically select a new clock from a plurality of clocks for comparison to a reference signal after division by an integer divide by N block. Based on a desired divider ratio, the state machine selects the new clock that is phase shifted with respect to a presently selected clock. Each change from the presently selected clock to the new clock produces a selected clock cycle that is expanded or contracted by the amount of phase shift between the new clock and the presently selected clock. The integer divide by N block divides the selected clock by the integer portion of the desired divider ratio producing a divided clock that is effectively divided by a non-integer amount.

Even when the lengths of data items to be transmitted to users are not the same, the frames multiplexed at the same time finally have the same frame length and are transmitted.

Even when the lengths of frames for the users are not the same at the time when a transmission request is received from a higher layer, a communication apparatus reconfigures at least two of the frames having short lengths into a frame having a long length through Aggregation so that the frames finally have the same frame length and transmits the frames at the same time in a multiplexed manner. On the transmitter side, the transmission power used per destination communication station can be increased due to a decrease in the total number of multiplexed frames. On the receiver side, an unstable AGC operation can be prevented.
