摘要： An encryption key matrix has rows grouped into segments, with a set of one segment per column establishing a slot. Slots are assigned to device manufacturers, with the keys of the slots then being assigned to decryption devices made by the respective manufacturer. In generating the slots, the number “q” of segments in a column is first defined such that a predetermined maximum number of devices can be revoked devices (in that all the keys held by the device are revoked) while ensuring that a good device remains a functional device with a probability of at least (1−Q), wherein Q is a predefined device confidence. Once the number “q” of segments has been defined, the slots themselves are defined in a provably non-discriminatory fashion using an error-correcting code such as a Reed-Solomon code. With this invention, overlap between slots can be minimized to minimize the possibility that the key set of an innocent device might be inadvertently revoked when the keys in the slots of a “bad” manufacturer are revoked.

摘要： A service that handles incoming telephone calls without bothering the telephone subscriber is disclosed. The service permits a call to go through to a subscriber if the service determines that the call is not unwanted and the caller has been unauthenticated. The authentication is based on challenging the caller to prove its identity rather than relying on caller ID displays. Prospective callers pre-register with the service providing caller account information. When a caller is issued a challenge, the caller may prove its authenticity by supplying the challenge back to the service along with its registered information.
摘要翻译： 公开了一种处理传入电话而不打扰电话用户的服务。 如果服务确定呼叫不是不需要的，并且呼叫者未经身份验证，则该服务允许呼叫转到订户。 认证是基于挑战来电者来证明其身份，而不是依靠来电显示。 预期来电者预先注册提供来电者帐户信息的服务。 当呼叫者发出挑战时，呼叫者可以通过向服务提供质询及其注册信息来证明其真实性。

摘要： A method for creating and maintaining threads of communications comprises accepting an electronic-communication call from a caller, determining if the caller is a new or previous caller by determining if a prior-caller user identification is contained within a call-receiving system, responsive to determining that the caller is a new caller assigning a new-caller user identification to the new caller and assigning a unique thread identification for communications related to a new issue, and responsive to determining that the caller is a known previous caller verifying a known-caller user identification and determining whether the known previous caller is calling about a new issue. Responsive to determining that the known previous caller is calling about a new issue, the method further includes assigning a unique thread identification to the new issue. Responsive to determining that the known previous caller is calling about an existing issue, the method further includes obtaining a list of previous thread identifications.

摘要： Exemplary embodiments of the present invention relate to enhanced faceted search support for OLAP queries over unstructured text as well as structured dimensions by the dynamic and automatic discovery of dimensions that are determined to be most “interesting” to a user based upon the data. Within the exemplary embodiments “interestingness” is defined as how surprising a summary along some dimensions is from a user's expectation. Further, multi-attribute facets are determined and a user is optionally permitted to specify the distribution of values that she expects, and/or the distance metric by which actual and expected distributions are to be compared.

摘要： The present invention provides a method of selectivity estimation in which preprocessing steps improve the feasibility and efficiency of the estimation. The preprocessing steps are partitioning (to make iterative scaling estimation terminate in a reasonable time for even large sets of predicates), forced partitioning (to enable partitioning in case there are no “natural” partitions, by finding the subsets of predicates to create partitions that least impact the overall solution); inconsistency resolution (in order to ensure that there always is a correct and feasible solution), and implied zero elimination (to ensure convergence of the iterative scaling computation under all circumstances). All of these preprocessing steps make a maximum entropy method of selectivity estimation produce a correct cardinality model, for any kind of query with conjuncts of predicates. In addition, the preprocessing steps can also be used in conjunction with prior art methods for building a cardinality model.

摘要： A system, method and program product for commerce management, especially for managing contingency agreements or contracts. An agreement is entered into the system, logging conditions for the agreement and identifying potential responses to satisfy each condition. A location may also be identified for each identified potential response, e.g. a HTML link to an internet web site. Milestones are set to determine when to check whether conditions have been satisfied. As each milestone is encountered information is retrieved from the locations or provided manually. The retrieved information is checked to determine whether the agreement is determinate, i.e., all of the conditions have been satisfied or, the agreement has failed because one condition will not be satisfied. If more conditions remain unsatisfied and are identified with subsequent milestones, the most recent milestone is recorded. The contracting parties are notified regarding status of the agreement and of passing any milestone. Notification and reminders may be by electronic mail (e-mail) or by more traditional mail.

摘要： Methods are provided for maximizing the throughput of a computer system in the presence of one or more power constraints. Throughput is maximized by repeatedly or continuously or periodically optimizing task scheduling and assignment for each of a plurality of components of a computer system. The components include a plurality of central processing units (CPUs) each operating at a corresponding operating frequency. The components also include a plurality of disk drives. The corresponding operating frequencies of one or more CPUs of the plurality of CPUs are adjusted to maximize computer system throughput under one or more power constraints. Optimizing task scheduling and assignment, as well as adjusting the corresponding operating frequencies of one or more CPUs, are performed by solving a mathematical optimization problem using a first methodology over a first time interval and a second methodology over a second time interval longer than the first time interval. The first methodology comprises a short term heuristic solver for adapting to computer system changes that occur on a short time scale, and the second methodology comprises a long term solver having greater accuracy and greater computational complexity than the first methodology.
