    • An RFID system and method for communicating between a host computer, one or more interrogators connected to the host computer, and a large body of transponders distributed within an area covered by the interrogators. Each transponder originally has a common identification code, and upon initialization by the host computer internally generates a unique identification code based upon an internally generated random number. The host, through the interrogators, reads each of the identification codes associated with each transponder by iteratively transmitting a read identification code command along with a controlled variable. Each transponder compares the received controlled variable to an internally generated random number, and selectively transmits its identification code based upon the outcome of this comparison. After the completion of each read identification code iteration, the host adjusts the controlled variable based upon the responses received in the previous iteration. Preferably, communications between the interrogators and the transponders are DSSS signals in TDMA format, and the transponders use the random number generator to assign a time slot for transmission of their response. Each interrogator includes an antenna system utilizing a switch matrix to connect multiple antennas having different polarizations, which ensures that all transponders within the range of the interrogator receive the signals from the interrogator. In a further aspect, the interrogators are arranged in groups, each group in nearest neighbor format, to reduce the time for reading the transponders and the emissions generated when more than one interrogator is active at the same time.
    • 用于在主计算机,连接到主计算机的一个或多个询问器和分布在由询问器覆盖的区域内的大量转发器之间进行通信的RFID系统和方法。 每个应答器最初具有公共识别码,并且在主计算机初始化之后,内部基于内部生成的随机数来生成唯一的识别码。 主机通过询问器通过迭代地发送读取的识别代码命令以及受控变量读取与每个转发器相关联的每个识别代码。 每个应答器将接收到的受控变量与内部产生的随机数进行比较,并且基于该比较的结果选择性地发送其识别码。 在每次读取识别代码迭代完成之后,主机根据在先前迭代中接收到的响应来调整受控变量。 优选地,询问器和应答器之间的通信是TDMA格式的DSSS信号,并且应答器使用随机数发生器为其响应的传输分配时隙。 每个询问器包括利用开关矩阵连接具有不同极化的多个天线的天线系统,这确保询问器范围内的所有应答器接收来自询问器的信号。 在另一方面,询问器被分组布置,每组以最邻近的格式排列,以减少用于读取应答器的时间和当多个询问器同时处于活动状态时产生的排放。

    • Embodiments herein present a method, system, computer program product, etc. for automated management using a hybrid of prediction models and feedback-based systems. The method begins by calculating confidence values of models. Next, the method selects a first model based on the confidence values and processes the first model through a constraint solver to produce first workload throttling values. Following this, workloads are repeatedly processed through a feedback-based execution engine, wherein the feedback-based execution engine is controlled by the first workload throttling values. The first workload throttling values are applied incrementally to the feedback-based execution engine, during repetitions of the processing of the workloads, with a step-size that is proportional to the confidence values. The processing of the workloads is repeated until an objective function is maximized, wherein the objective function specifies performance goals of the workloads.
    • 本文的实施例提出了使用预测模型和基于反馈的系统的混合的自动化管理的方法,系统,计算机程序产品等。 该方法从计算模型的置信度开始。 接下来,该方法基于置信度值选择第一模型,并通过约束求解器处理第一模型以产生第一工作负载节流值。 此后,通过基于反馈的执行引擎重复处理工作负载,其中基于反馈的执行引擎由第一工作负载节流值控制。 在重复处理工作负载期间,第一个工作负载限制值将逐步应用于基于反馈的执行引擎,步长与置信度值成比例。 重复处理工作负载直到目标函数最大化,其中目标函数指定工作负载的性能目标。
