A salicide layer is deposited on the source/drain regions of a PMOS transistor. A dielectric capping layer having residual compressive stress is formed on the salicide layer by depositing a plurality of PECVD dielectric sublayers and plasma-treating each sublayer. Compressive stress from the dielectric capping layer is uniaxially transferred to the PMOS channel through the source-drain regions to create compressive strain in the PMOS channel. To form a compressive dielectric layer, a deposition reactant mixture containing A1 atoms and A2 atoms is provided in a vacuum chamber. Element A2 is more electronegative than element A1, and A1 atoms have a positive oxidation state and A2 atoms have a negative oxidation state when A1 atoms are bonded with A2 atoms. A deposition plasma is generated by applying HF and LF radio-frequency power to the deposition reactant mixture, and a sublayer of compressive dielectric material is deposited. A post-treatment plasma is generated by applying HF and LF radio-frequency power to a post-treatment gas that does not contain at least one of A1 atoms and A2 atoms. Compressive stress in the dielectric sublayer is increased by treating the sublayer in the post-treatment plasma. Processes of depositing a dielectric sublayer and post-treating the sublayer in plasma are repeated until a desired thickness is achieved. The resulting dielectric layer has residual compressive stress.

Critical needs for MRI patient instruction, testing, comfort, motion control, and speech communication are provided for better imaging which leads to more effective medical care.

A method for rendering adjacent polygons. The method includes determining when a first polygon and a second polygon have an abutting edge. If an abutting edge exists, a majority status is assigned to a pixel on the abutting edge. A first color of the first polygon or a second color of the second polygon is then allocated to the pixel in accordance with the majority status.

A system and a method for reverse link power control in a wireless communications network generates power adjust commands for mobiles being served by a network base station in a centralized manner by considering overall system performance when an increased interference condition is detected. In one implementation, a base station power control processor adopts a modified reverse inner loop power control (RILPC) and/or a reverse outer loop power control (ROLPC) algorithm when an increased interference condition is detected. According to the modified RILPC algorithm, a percentage of power-up adjust commands which would normally be generated when E_b/N_o measurements for served mobiles do not meet target E_b/N_o levels are converted to power down-adjust commands, thereby forcing some mobiles to reduce transmit power, at least temporarily, to constrain interference. When the increased interference condition persists, the percentage of power-up adjust commands which are converted to power-down commands may be changed. According to the modified ROLPC algorithm, the power control processor adjusts target E_b/N_o levels in a centralized manner based on an overall system state so that only a limited number of target E_b/N_o levels are allowed to increase when frame erasures occur. By preventing a percentage of target E_b/N_o level increases, at least temporarily, when frame erasures occur, a percentage of power up-adjust commands are avoided. Therefore, a similar effect to that achieved by the modified RILPC is achieved. In accordance with still a further implementation of the present invention, the modified RILPC algorithm may be used in combination with the modified ROLPC algorithm to provide greater resistance to increased interference conditions.

Methods and systems are provided for displaying images onto an arbitrary surface, using a projector, such that the quality of the images is preserved despite surface imperfections or color variations. Methods and systems are also provided for controlling the appearance of a projection surface. Various embodiments use a detailed radiometric model and a calibration method to determine the pixel values required to be projected by a projector in order for a camera to observe a desired image. Other embodiments use a compensation algorithm that uses a feedback approach to provide the desired image compensation. Geometric mapping may be used to establish a correspondence between points in the images to be displayed by the projector and the corresponding points in the images that are captured by the camera.

A method for producing paper pulp from a lignocellulosie vegetable raw material. The method includes contacting the raw material with a mixture of formic acid and acetic acid (in an amount more than 5 wt. % of the mixture) at a temperature and for a suitable reaction time, the whole being performed at room temperature. The paper pulp is separated from the organic phase and optionally bleached with ozone. The organic phase is treated to enable the recycling of the formic and acetic acids and the extraction of lignins, sugars and excess acetic acid.

Disclosed is a method, system, and program for reducing toner in an image comprised of raster pel data. A determination is made of pels surrounding subject pels. For each subject pel, a sub-pulse width power is generated to charge a sub-pel region within the subject pel based on a pattern of the surrounding pels of the subject pel. Further, for each subject pel, position information is generated indicating an alignment of the sub-pel region in the pel. The position information is used to position the sub-pel region produced by the sub-pulse width power in the pel.

A computer alters at least one recognizable metric or text in a digitally-encoded photographic image by operating an alteration algorithm in response to user input data while preserving an overall aesthetic quality of the image and obscuring an identity of at least one individual or geographic location appearing in the image. An altered digitally-encoded photographic image prepared by the altering of the at least one recognizable metric or text in the image is stored in a computer memory. User feedback and/or automatic analysis may be performed to define parameter values of the alteration algorithm such that the alteration process achieves preservation of aesthetic qualities while obscuring an identity of interest.

Methods and apparatus for providing access to program channels, e.g., high definition programs and program channels which corresponding to a standard definition program and/or program channels are described. In accordance with the invention, a high definition auto tune function is supported. When enabled, in one exemplary embodiment, if a user selects a standard program definition channel, a check is automatically made to determine if a corresponding high definition program channel is available. The corresponding high definition program channel is a channel which provides the same program as on the selected standard definition channel but in high definition. When the auto tune function is enabled and a corresponding high definition channel is available, the device, e.g., set to box or tuner implementing the auto tune feature of the present invention, automatically tunes to the high definition channel instead of the standard definition channel. The content from the high definition channel is then displayed instead of the content from the user selected standard definition channel.
