摘要： An e-commerce mechanism tries to dynamically estimate or refine a profile of a buyer and hence change their negotiation strategy in a dynamic and an on-line manner. An e-commerce site can negotiate with a customer based on his or her profile. The e-commerce site may sell one or more types of items to various customers. These customers may be brokers, other intermediaries, businesses or consumers. Similarly, the e-commerce site may be a broker, an auctioneer, an intermediary, a seller, or even a manufacturer. In one specific case of this invention, the existing data on various customers' past purchases, buying behavior, demographics and other parameters is studied to arrive at attributes which are then used to segment customers into various profiles. The profiles depend not only on the demographic factors but also on factors like the season, the time of day, the geographical area and the cultural upbringing. When a new customer comes to the e-commerce site, the customer is assigned to a pre-specified profile in an on-line manner. The e-commerce site then negotiates with the customer according to the customer's present profile. As the customer negotiates, the customer's profile is dynamically updated to incorporate the customer's actions. Different profiles may yield different negotiation strategies and also different results, i.e., value, price, points, delivery dates, etc. Both the customer and the e-commerce site can negotiate on the basis of each other's dynamic profiles and come to a mutually agreed settlement.
摘要翻译：电子商务机制试图动态地估计或改进买方的资料，从而以动态和在线的方式改变他们的谈判策略。电子商务网站可以根据他或她的个人资料与客户进行协商。电子商务网站可能会向各种客户销售一种或多种类型的商品。这些客户可能是经纪人，其他中间商，企业或消费者。类似地，电子商务网站可以是经纪人，拍卖人，中间商，卖方，甚至制造商。在本发明的一个具体情况下，研究了关于各种客户过去购买，购买行为，人口统计学和其他参数的现有数据，以获得随后用于将客户分成各种简档的属性。简介不仅取决于人口因素，还依赖于季节，时间，地理区域和文化养育等因素。当新客户来到电子商务网站时，客户将被分配到一个预先指定的配置文件中。然后，电子商务网站将根据客户现在的情况与客户进行协商。客户协商后，客户的配置文件将被动态更新，以纳入客户的行为。不同的配置文件可能产生不同的协商策略，也可能产生不同的结果，即价值，价格，点数，交货日期等。客户和电子商务网站都可以基于彼此的动态配置文件进行协商，并达成共同商定沉降。

摘要： Techniques and apparatus for controlling the transmit power of an uplink (UL) signal from a user terminal in a wireless communications system in an effort to achieve some target characteristic, such as a target carrier-to-interference (C/I) ratio, at an access point (AP) are provided. In this manner, such a user terminal may help avoid or compensate for imbalances in received radio frequency (RF) power between UL signals received from multiple user terminals by the AP. For example, the transmit power at each user terminal may be controlled in an effort to achieve a target post-processing C/I ratio of 28 dB per spatial stream in an effort to reduce large power imbalances and optimize throughput per user terminal. The user terminal and the AP may compose part of a multiple-input multiple-output (MIMO) communication system utilizing spatial-division multiple access (SDMA) techniques.

摘要： Apparatuses and methods for adjusting wireless-derived positions of a mobile station using a motion sensor are presented. One method includes estimating a position of a mobile station based upon wireless signal measurements and measuring a movement of the mobile station using a relative motion sensor. The method further includes detecting a displacement of the mobile station based upon the measured movement, determining that the displacement is below a threshold and then adjusting the estimated position of the mobile station using information from the relative motion sensor. An apparatus includes a wireless transceiver, a relative motion sensor, a processor coupled to the wireless transceiver and the relative motion sensor, and a memory coupled to the processor. The memory stores executable instructions and data for causing the processor to execute methods for adjusting wireless-derived positions using a motion sensor.
