Abstract: The distribution of chemical compounds in high-dimensional molecular descriptor space can be viewed in two dimensions by applying the projection method of this invention. This method has particular usefulness for viewing the relationships of a large number of compounds such as found in a large scale HTS or virtual combinatorial library. After selecting a representative subset of the larger data set of comounds, initially components from the high-dimensional descriptor space are determined by PCA. In order to relax an NLM projection using the PCA components as a start, the stress function is modified to reflect a local horizon beyound which the separation of the compounds is not meaningfully measureable. The resulting two dimensional projections provide a clear insight into the distribution of the chemical compounds in the higher dimensional space.

Abstract: A method for automatically setting valve clearances in internal combustion engines (also known as “tappet setting” or “valve lash setting”) comprises a series of steps in which a rocker arm is set to a zero position that is recorded as a reference datum and an adjustment screw is then operated to set the rocker arm to a first reference position. The adjustment screw is then rotated through a predetermined angle so that the rocker arm is moved to a second reference position. The difference between the first and second reference positions and the predetermined angle are used to determine a coefficient relating the angular movement of the adjustment screw to linear movement of the rocker arm. The coefficient is then used to calculate the angular rotation of the adjustment screw required to set a predetermined valve clearance relative to the zero position.

In response to the edge and its reflection, the first and second inputs of the measurement circuit each see a first voltage step and a second voltage step. The interval between the first and second voltage steps is then measured for each input of the measurement circuit.

Abstract: A system and method for testing the quality of a simulation model for the DUT (device under test) through temporal coverage of the testing and verification process. Temporal coverage examines the behavior of selected variables over time, according to a triggering event. Such a triggering event could be determined according to predefined sampling times and/or according to the behavior of another variable, for example. This information is collected during the testing/verification process, and is then analyzed in order to determine the behavior of these variables, as well as the quality of the simulation model for the DUT. For example, the temporal coverage information can be analyzed to search for a coverage hole, indicated by the absence of a particular value from a family of values.

Abstract: A method for designing and mapping a power-bus grid in an integrated circuit. A floor plan is created by mapping wire segments of the power-bus grid to various metal layers of the IC core. Power zones which specify the current consumption of analog, digital, and memory block regions are also mapped to the IC core. A netlist of the floor plan design is generated and simulated, with the simulation returning current density and a voltage drop values in the wire segments with respect to the power zones. Calculated current density and voltage drop values are analyzed using a color map to indicate the current density and voltage drop levels of the wire segments. Power-bus wire segments are displayed in colors matched to the current density and voltage drop levels in the color map, helping the designer identify potential electromigration and voltage drop problems. The floor plan design can be modified if the calculated density and voltage drop values indicate potential electromigration or voltage drop problems.

Abstract: An input content signal—representing audio or video—is encoded to hide plural-bit auxiliary data therein. The process generates an intermediate signal that is a function of (a) the plural-bit auxiliary data, and (b) data related to human perception attributes of the content signal. This intermediate signal is then summed with the content signal to effect encoding. The plural-bit auxiliary data can include copy control data, i.e., data that can be sensed by a consumer electronic device and used to disable a copying operation. The intermediate signal may include a pseudo-random key signal so as to obscure the encoding and require knowledge of a corresponding key at the decoder to extract the auxiliary data from the encoded content. In some embodiments, calibration data is encoded in the content signal with the auxiliary data. This calibration data desirably has known properties (e.g., spectral attributes, data content, etc.) facilitating its identification in the encoded content signal.

Abstract: A lossless coding method may be used to compress information, such as audio data, without introducing any artifacts. This lossless coding method may be used to compress audio signals for use in storage and/or transmission of audio data. The audio data may be compressed by first dividing digital samples taken from the audio data into frames. A predictor is then used on the frames to generate prediction coefficients that can then be quantized to form predictor bits. The frames may then be subdivided into subsets. Another predictor can be used on the subsets to produce error samples that can be entropy coded into codeword bits. The predictor bits and codeword bits can be included in the compressed audio output for use in decoding.
