摘要： In controlling fuel injection and ignition timing in an internal combustion engine operating on a fuel mixture, such as gasoline and methanol, consideration must be given to the mixture ratio of the fuel mixture in determining air/fuel ratio and ignition timing, as well as in controlling the atomizing of the injected fuel. Fuel injection time is determined in accordance with air/fuel ratio, which is calculated in accordance with the expressionA/F=14.8-0.0853Pfor a fuel mixture of gasoline and methanol, where P is the mixture ratio of methanol. In addition, to enhance cold start performance, a droplet size of injected fuel below 100.mu. is desired, and this may be achieved using a heating element whose surface temperature is controlled in accordance with the mixture ratio P or by injecting compressed air with the injected fuel in an amount determined by the mixture ratio P, or both. In the alternative, an ultrasonic fuel injector may be employed whose frequency is controlled in accordance with the mixture ratio P.

摘要： Antennas with steerable antenna patterns and techniques for using such antennas are described. In accordance with the invention, antenna patterns with one or more NULLs are used. Through the use of digital control signals the antenna pattern is steered so that a source of signal interference, e.g., a multipath signal, will be located in a NULL. In this manner the received signal's S/N ratio can be maximized thereby facilitating demodulation. The techniques of the invention can be applied to television, computer devices, mobile devices and a wide range of other systems. Digital commands to control an antenna may include multiple information fields, e.g., a direction field, a channel field, a gain field and a polarity field. Antennas incapable of supporting the specified fields disregard information in fields which are not supported. Information in each supported field is decoded and used to adjust the corresponding antenna characteristic.

摘要： The present invention relates to analysis of large, disk resident data sets using a Patient Rule Induction Method (PRIM) in a computer system wherein a relational data table is initially received. The relational data table includes continuous attributes, discrete attributes, a matter parameter and a cost attribute. The cost attribute represents cost output values based on continuous attribute values and discrete attribute values as inputs. A hyper-rectangle is then formed which encloses a multi-dimensional space defined by the continuous attribute values and the discrete attribute values. The continuous attribute values and the discrete attribute values are represented as points within the multi-dimensional space. A plurality of points along edges of the hyper-rectangle are then removed based on an average of the cost output value from the plurality of points until a count of the points enclosed within the hyper-rectangle equals the meta parameter. Discrete attribute values and continuous attribute values which were removed from the hyper-rectangle are next added along edges of the hyper-rectangle until a sum of the cost output value over the multi-dimensional space enclosed by the hyper-rectangle changes. In a further embodiment a parallel architecture computer system calculates the cost attribute average values over the plurality of points enclosed by the hyper-rectangle in parallel. The invention analyzes large disk resident data sets without having to load the data set into main memory and can be practiced on a parallel computer architecture or a symmetric multi-processor architecture to improve performance.
摘要翻译：本发明涉及在计算机系统中使用患者规则诱导方法（PRIM）分析大的盘驻留数据集，其中最初接收关系数据表。关系数据表包括连续属性，离散属性，事物参数和成本属性。成本属性表示基于连续属性值和离散属性值作为输入的成本输出值。然后形成超矩形，其包围由连续属性值和离散属性值定义的多维空间。连续属性值和离散属性值表示为多维空间内的点。然后根据多个点的成本输出值的平均值去除超矩形边沿的多个点，直到包含在超矩形内的点的计数等于元参数。从超矩形移除的离散属性值和连续属性值接下来沿着超矩形的边缘添加，直到由超矩形包围的多维空间的成本输出值的总和发生变化。在另一实施例中，并行架构计算机系统并行计算由超矩形包围的多个点上的成本属性平均值。本发明分析大盘驻留数据集，而不必将数据集加载到主存储器中，并且可以在并行计算机体系结构或对称多处理器架构上实践以提高性能。

摘要： A portable electronic data storage/processing device, e.g., smart card maintains an account including benefit packages. Each benefit package includes multiple items with associated quantity information. A smart card includes an account benefits interface and a retailer interface, each interface using different security measures. New benefit packages are added to the smart card through the account benefit interface by a benefit provider. Benefits debit request lists including multiple items and associated quantities are submitted to the smart card through the retailer interface. The smart card is the trusted member and checks if all requested items in quantities requested can be debited. If all requests can be fulfilled, the smart card executes the debiting from the currently valid benefit package and returns a transaction success indication to the retailer. If any of the requests of the list cannot be met, the entire request list is rejected and no debiting occurs. Benefit quantity addition is not possible through the retailer interface. Transactions are performed as block transactions.

摘要： Methods and apparatus for implementing a reduced cost HDTV/SDTV video decoder are disclosed. The described joint video decoder is capable of decoding HDTV pictures at approximately the resolution of standard definition television pictures and can be used to decode HDTV and/or SDTV pictures. The described video decoder may be used as part of a picture-in-picture decoder circuit for providing picture-in-picture capability without providing multiple full resolution video decoders. The reduction in decoder circuit complexity is achieved through the use of a plurality of data reduction techniques including the use of a preparser, downsampling, and truncating pixel values.

摘要： A system and method for providing advertisements to a wireless remote display terminal. The terminal may display Internet web sites and other data while a viewer is also watching a television channel or performing other tasks. For example, a home entertainment center can include a television and an additional remote display terminal. Viewers can access information related to the television program on the remote display terminal. When the remote display terminal is turned on, a personalized advertisement is displayed to the viewer during the initialization process. The advertisement revenues can help offset the cost of the remote terminal to the viewer. The advertisements can be targeted to particular users by matching the advertisements to personal information obtained by surveys, past viewing and Internet history or third party sources such as magazine subscriptions.

摘要： Methods and apparatus for implementing video decoders at a reduced cost are described. The methods include data reduction techniques, simplified inverse quantization techniques, and dynamically varying the complexity of image enhancement operations, e.g., prediction filtering operations, as a function of whether luminance or chrominance data is being processed. In order to reduce data storage requirements, luminance and chrominance data corresponding to previously encoded images may be stored at different resolutions with, in some embodiments, chrominance data being stored at less than half the resolution of luminance data. In various embodiments, data representing portions of B frames which will not be displayed is identified and discarded, e.g., without performing a decoding operation thereon. Portions of I and P frames which will not be displayed are identified and decoded at a reduced resolution and/or using simplified inverse quantization techniques. The decoded I and P frame data is stored for use when making subsequent predictions if required. Another data reduction technique involves applying different amounts of data reduction, e.g., downsampling, to different image portions with no or little downsampling being performed on image portions located at or nearest to the image's center of interest as determined from information included in a received encoded bitstream.
