    • Provided is a generalized Recursive STTC (Space-Time Trellis Code) encoder which can improve diversity gain and coding gain in terms of transmission without increasing circuit complexity in a transmission system by forming an internal encoder of a multi-antenna mobile telecommunication system using a Recursive Systematic Convolutional code (RSC) block having two output ends to form a systematic ineral encoder. In addition, the generalized RSTTC encoder has a ratio of input data to output data (n−1):n by using a plurality of parallel RSC blocks each having two output ends. Thus, flexibility can be given to the size of data input to each RSC block and a transmission data rate can be improved in the internal encoder of a transmission system.
    • 提供了一种广义递归STTC(空时网格码)编码器,其可以在传输系统中提高分集增益和编码增益,而不会增加传输系统中的电路复杂度,通过使用递归的多天线移动电信系统的内部编码器 具有两个输出端的系统卷积码(RSC)块,形成系统的自然编码器。 此外,广义RSTTC编码器通过使用多个具有两个输出端的并行RSC块,具有输入数据与输出数据(n-1):n的比率。 因此,可以灵活地输入到每个RSC块的数据的大小,并且可以在传输系统的内部编码器中改善传输数据速率。

    • A system and related techniques automatically analyze Web search and other activity, to generate locality-selected results based on not just the user's location, but also the business or other content provider's location and the degree of local intent in the user's query. The locality or region to the user may be identified, for instance, by the presence of geographic clues or indicators in the general content of the Web site, for instance, the presence of ZIP codes, telephone numbers, town names or other semantic or other indicators which have some geographic connotation in search terms, key words or other query or semantic inputs. The user's degree of local intent may be automatically analyzed as well, for instance by the presence of terms such as “car repair” or “pizza restaurant” which may suggest the user intends to locate local goods, services or providers. The search service may then access a content database to identify ads or other media or content which match or correspond to the detected locality or region, such as ads for local restaurants, car dealerships, physicians or other services or products, and which correspond in location, working radius and degree of localness to the user's query. Because the delivery of localized search results according to the invention is specifically filtered for user-driven local intent, advertisements and other media or content may be delivered which better match the user's search objectives.
    • 系统和相关技术自动分析Web搜索和其他活动,根据用户的位置,以及业务或其他内容提供商的位置以及用户查询中的本地意图程度来生成位置选择的结果。 例如,可以通过在网站的一般内容中存在地理线索或指示符来识别用户的本地或区域,例如,邮政编码,电话号码,城市名称或其他语义或其他方面的存在 在搜索词,关键词或其他查询或语义输入中具有某些地理内涵的指标。 也可以自动地分析用户的本地意图程度,例如通过存在诸如“汽车修理”或“比萨餐馆”这样的术语,其可以建议用户打算定位本地商品,服务或提供者。 然后,搜索服务可以访问内容数据库以识别匹配或对应于检测到的地点或区域的广告或其他媒体或内容,例如本地餐馆,汽车经销商,医生或其他服务或产品的广告,并且其位置对应 ,工作半径和用户查询的本地化程度。 由于根据本发明的本地化搜索结果的递送被特定地过滤以用于用户驱动的本地意图,所以可以传送与用户的搜索目标更好匹配的广告和其他媒体或内容。

    • This device is related to the domain of fully automatic machines for oil extraction. An axle transmission and soft belt suspension system is used in the device. A decelerator connects an electric motor and a driving hub, so that the transmission belt can be driven. When the driven hub and the bridle are connected, the sucker rod will be connected so that the oil-well pump can start working. There are several other units, an absolute value coder that can measure the driven hub's angle of rotation, a augmenter coder that can measure the rotational speed of the electric motor and an oil gauge. In the device, a oil production process controller processes collects signals and then the device controls the machine, the beam and the pump system automatically. It has the advantages of saving energy, high efficiency for oil extraction and long operational life span.

    • A metric representing the sum of variances for pixel blocks of a region of an image are used to identify the presence a video feature of the image, and a transcoding is performed responsive to identifying the presence of the video feature. The identified video feature can include, but is not limited to, a scene change, the presence of a black border region or a caption region, or the complexity of the image. The transcoding operation can include, but is not limited to, coding the image as an Intra-frame, omitting the content corresponding to the black border region or the caption region from the transcoded image or allocating a relatively lower bit budget for the black border region or a relatively higher bit budget to the caption region during transcoding of the image, or setting the bit budget for rate control during transcoding.
