    • Some embodiments relate to an apparatus for metallic particulate detection. The apparatus comprises: an entry stage defining an input chamber to receive an element having particulate matter thereon; a sensor defining a passage in fluid communication with the input chamber to receive the particulate matter from the input chamber and to detect the particles in the particulate matter; a vented recovery stage defining a recovery chamber to receive and capture at least some of the particulate matter passing through the passage; and at least one air outlet positioned in the input chamber to direct pressurized air from the at least one air outlet to impinge on the element to remove the particulate matter from the element.
    • 一些实施例涉及用于金属颗粒物检测的装置。 该装置包括:入口台,其限定输入室以接收其上具有颗粒物质的元件; 传感器限定与输入室流体连通的通道,以从输入室接收颗粒物质并检测颗粒物质中的颗粒; 通气回收阶段限定回收室以接收和捕获通过通道的至少一些颗粒物质; 以及位于输入室中的至少一个空气出口,用于将来自至少一个空气出口的加压空气引导到元件上以从该元件去除颗粒物质。

    • Embodiments are configured to manage memory, including detecting one or more memory leaks. The various embodiments are configured to detect memory leaks and/or associated data without adding extra space or overhead for each associated memory allocation as compared with current implementations. In an embodiment, memory is managed including the detection a memory leak by using a fixed memory overhead, such as a fixed block or buffer of N pointers, instead of adding extra space per memory allocation. The contents of the fixed block can be altered and used to detect when memory has been allocated but not freed based on an analysis of a polynomial associated with one or more allocation and free operations. The polynomial can be solved to determine leaked pointers under certain conditions.
    • 实施例被配置为管理存储器,包括检测一个或多个存储器泄漏。 各种实施例被配置为检测存储器泄漏和/或相关联的数据,而不需要为每个相关联的存储器分配增加额外的空间或开销,与当前的实现相比。 在一个实施例中,管理存储器,包括通过使用固定存储器开销(诸如N个指针的固定块或缓冲器)来检测存储器泄漏,而不是每个存储器分配增加额外的空间。 基于与一个或多个分配和空闲操作相关联的多项式的分析,固定块的内容可以被改变并用于检测何时已经分配了存储器但不被释放。 可以解决多项式以确定在某些条件下的泄漏指针。
