摘要： A method of segmenting relative user preferences into fine-grain and coarse-grain collections is provided. The method includes providing a set of content items having associated descriptive terms. The method also includes receiving user search input and, in response thereto, presenting a subset of content items. The method includes receiving user selection actions and analyzing the selections to learn the user's preferred descriptive terms. The method includes expressing the learned preferred descriptive terms as a segmented probability distribution function having at least one fine grain segment and at least one coarse grain segment. In response to subsequent search input, the method calls for selecting and ordering a collection of content items by promoting the ranking of content items associated with the learned preferred descriptive terms of the user according to the differentiation provided by the segmented probability distribution function.

摘要： A system for delivering power over a network of devices connected through a serial link includes a first and second differential pairs of wires. Each differential pair of wires is double AC coupled by a HPF on one side and by another HPF on an opposite side. An LPF connects a portion of each differential pair of wires between the HPFs to a voltage source, and another LPF connects that portion of each differential pair to a load. The system further includes a third and fourth differential pairs of wires. All four differential pairs of wires are located within a single cable, such as a CAT6 cable. The first, second and third differential pair of wires are used for video links, and the fourth differential pair of wires are used for the bi-directional hybrid link. A power delivery circuit in each device includes a voltage source, a power relay switch, a signature resistor for detection, and a load detector.

摘要： The invention provides a cache architecture that selectively powered-up a portion of data array in a pipelined cache architecture. A tag array is first powered-up, but the data array is not powered-up during this time, to determine whether there is a tag hit from the decoded index address comparing to the tag compare data. If there is a tag hit, during a later time, a data array is then powered-up at that time to enable a cache line which corresponds with the tag hit for placing onto a data bus. The power consumed by the tag represents a fraction of the power consumed by the data array. A significant power is conserved during the time in which the tag array is assessing whether a tag hit occurs while the data array is not powered-on at this point.
摘要翻译：本发明提供一种高速缓存架构，其选择性地加电流水线高速缓存结构中的数据阵列的一部分。标签阵列首先被加电，但在此期间数据阵列未上电，以确定与标签比较数据相比，是否存在来自解码的索引地址的标签命中。如果有一个标签命中，在稍后的时间内，数据阵列然后被加电，以启用与标签命中对应的高速缓存行放置在数据总线上。标签消耗的功率代表数据阵列消耗的功率的一小部分。在标签阵列评估在此时数据阵列未通电的情况下是否发生标签命中的时间内，节省了大量功率。
