摘要： A method includes advertising a policy characterizing communication properties supported by a node. The policy may be distributed to another node in response to a request for the policy. Policy expressions in the policy include one or more assertions that may be grouped and related to each other in a plurality of ways. A system includes a policy generator for generating at least one policy characterizing properties of a node. A policy retriever retrieves a policy from another node and a message generator generates a message to the other node, wherein the message conforms to the policy from the other node.

摘要： Implementations are described and claimed herein to detect an invalid policy that may reside in a cache at a client. An expired policy is removed from cache and a current policy is requested. Otherwise the cached policy may be used. The client indicates which policy it is using by generating a policy digest, including, in compressed form, one or more assertions. If the host determines the policy digest is invalid, the host issues an invalid digest fault. If the policy digest is valid, but the assertions included in the policy digest are invalid, the host issues an invalid policy fault. In either case, the client is notified that the cached policy is no longer valid and that a current policy should be requested.

摘要翻译： 这里描述和要求的实现来检测可能驻留在客户端的高速缓存中的无效策略。 从缓存中删除过期的策略，并请求当前策略。 否则可能会使用缓存的策略。 客户端通过生成策略摘要来指示其使用哪个策略，包括压缩形式的一个或多个断言。 如果主机确定策略摘要无效，则主机发出无效的摘要故障。 如果策略摘要有效，但策略摘要中包含的断言无效，则主机发出无效的策略故障。 在任一情况下，通知客户端缓存的策略不再有效，并且应该请求当前的策略。

摘要： This disclosure shows how a time series of measurements of an evolving system can be processed to create an “inner” time series that is unaffected by any instantaneous invertible, possibly nonlinear transformation of the measurements. An inner time series contains information that does not depend on the nature of the sensors, which the observer chose to monitor the system. Instead, it encodes information that is intrinsic to the evolution of the observed system. Because of its sensor-independence, an inner time series may produce fewer false negatives when it is used to detect events in the presence of sensor drift. Furthermore, if the observed physical system is comprised of non-interacting subsystems, its inner time series is separable; i.e., it consists of a collection of time series, each one being the inner time series of an isolated subsystem. Because of this property, an inner time series can be used to detect a specific behavior of one of the independent subsystems without using blind source separation to disentangle that subsystem from the others. The method is illustrated by applying it to: 1) an analytic example; 2) the audio waveform of one speaker; 3) mixtures of audio waveforms of two speakers.

摘要： Techniques are described to mitigate ad stalking and other user concerns resulting from user-targeted advertising. A user may be informed of advertising information by a process in which an advertising server receives a request for an ad. The request may have been generated in response to a user request for a landing web page. An ad may be selected based on user information available to the advertising server, where the user information is associated with the user and describes behavior and/or attributes and/or preferences associated with the user. Text about how the ad was selected may be incorporated into the ad. Such text may describe the user information used to select the ad. The selection-disclosing text may be incorporated in the ad in a form that is displayable to the user by a browser. The ad may then be transmitted for display in the landing web page.

摘要： A portable apparatus for detecting the presence of at least one methylxanthine chemical species such as caffeine or theophylline in a beverage comprises a first portion comprising an effective concentration of phosphodiesterase enzyme, a second portion comprising cyclic AMP, and means for indicating inhibition of degradation of the cyclic AMP by the phosphodiesterase due to the presence of the methylxanthine species. A method for determining the presence of at least one methylxanthine chemical species in a beverage comprises contacting at least one test portion of the beverage with effective concentrations of at least one phosphodiesterase enzyme and cyclic AMP, and further contacting the test portion with means for indicating the inhibition of the degradation of the cyclic AMP by the phosphodiesterase due to the presence of the methylxanthine species. The apparatus and method are advantageous in that they provide a simple and effective means of determining whether methylxanthine chemical species such as caffeine or theophylline are present in coffee, tea and other beverages.

摘要： Given a time series of possibly multicomponent input data, the method and apparatus includes a device that finds a time series of “source” components, which are possibly nonlinear combinations of the input data components and which can be partitioned into groups that are statistically independent of one another. These groups of source components are statistically independent in the sense that the phase space density function of the source time series is approximately equal to the product of density functions, each of which is a function of the components (and their time derivatives) in one of the groups. In a specific embodiment, an unknown mixture of data from multiple independent source systems (e.g., a transmitter of interest and noise producing system) is processed to extract information about at least one source system (e.g., the transmitter of interest).

摘要： Displaying graphical indicators, instead of data, based on user-defined conditions. The user can specify conditions for displaying graphical indicators instead of actual data by specifying a test, values, and an image. The graphical indicators can be pre-assigned images that are dynamically applied based on the underlying text or numeric data values. Graphical indicators allow the user to visually represent data types or categories with graphics, based on the user's conditions. Different conditions can be specified for a given data field and each condition can be associated with a particular graphical indicator. Prioritized processing of data conditions allow for complex control of which indicator will be displayed to visually represent the data. When the underlying data in a field changes, the criteria can be reapplied and the field dynamically updated to the appropriate indicator.
