    • Described are techniques to facilitate temporal features in a semantic data store. Information about lifetimes of facts in a semantic store is maintained. Even when a fact is logically deleted, a physical record is kept available. The record of a logically deleted or invalid fact has associated lifetime information. For example, valid-from and valid-to time values. The record of a fact not yet deleted may have a valid-from time value indicating when it was created, became valid, etc. Queries against the semantic store may specify a timeslice (a point in time or a time range). The lifetime information can be used to satisfy such time-specific queries. Because records are maintained after they are logically deleted, it is also possible to accurately query a past state of the semantic store. Even if such a query is run at different times, same results may be obtained.
    • 描述了促进语义数据存储中的时间特征的技术。 维护关于语义商店中事实的生命周期的信息。 即使事实被逻辑删除,物理记录仍然可用。 逻辑删除或无效事实的记录具有关联的生命周期信息。 例如,从有效到有效到时间值。 尚未被删除的事实的记录可以具有指示何时被创建,变得有效的有效时间值。对于语义存储的查询可以指定时间片(时间点或时间范围)。 生命周期信息可用于满足这种特定于时间的查询。 因为记录在逻辑删除之后被维护,所以也可以准确地查询语义存储的过去状态。 即使这样的查询在不同的时间运行,也可以获得相同的结果。

    • A product retrieval system for vending machines that permits collection of varying size products at a first level yet presents such products for collection at a raised height to make retrieval more convenient. The retrieval system utilizes a rotary hopper that includes an actual bottom as well as a technical or false bottom that does not lower the depth of the rotary hopper in its ability to receive dispensed product on the actual bottom, with the technical bottom presenting the product to a higher retrieval point relative to the floor upon rotation of the rotary hopper to an open condition.

    • The method includes the following steps—introducing a low amplitude air pressure transient into the drainage and vent system of a building in order to propagate a pressure wave from a fitting (6) into a stack (1) and the network of the drainage system; —recording the passage of the transient by use of an air pressure transducer (7) located near the fitting (6) or introduction area of the transient; —establishing a pressure versus time signature recorded by the pressure transducer (7) and sending those signals to a central data acquisition system; —the pressure transient is propagated throughout the network at an acoustic velocity and is reflected by each and every pipe termination of the network so as to establish a characteristic reflection coefficient for each pipe termination; —the characteristic reflection coefficient is compared with testing results performed initially in a perfect network with no dry trap defects or leakages and in case a different signature is of the pressure trace is recorded, the point of diversion will be determined at the time at which the reflection from the altered pipe end termination arrives at the air pressure transducer so that the comparison of this direct trace with the stored defect free signature yields that time and, as the wave speed is known, the determination of the distance from the pressure transducer to the defective trap or seal.
    • 该方法包括以下步骤:将低振幅气压瞬变引入建筑物的排水和排气系统,以将压力波从配件(6)传播到堆(1)和排水系统的网络; - 通过使用位于配件(6)附近的空气压力传感器(7)或瞬态的引入区域来记录瞬态通过; - 建立由压力传感器(7)记录的压力与时间签名,并将这些信号发送到中央数据采集系统; - 压力瞬变以声速传播到整个网络,并由网络的每个管终端反射,以建立每个管终端的特征反射系数; 将特征反射系数与最初在没有干阱缺陷或泄漏的完美网络中执行的测试结果进行比较,并且如果记录了不同的签名是压力迹线,则转移点将在 来自改变的管端终端的反射到达空气压力传感器,使得该直接迹线与存储的无缺陷签名的比较产生该时间,并且随着波速已知,确定从压力传感器到 陷阱或密封有缺陷。
