Abstract: This application is directed to a shock sensor mounted in an electronic device. The shock sensor includes both active and passive shock detection methods that allow a technician to determine whether the electronic device was subjected to a shock event that exceeded an impact threshold level. The shock sensor may include shock detection contacts that form an electrical circuit that remains open in the absence of a shock event that exceeds an impact threshold level. In response to a significant shock event, a movable component or substance of the shock sensor may move from a first position to a second position, thereby closing the electrical circuit formed by the shock detection contacts. The change in circuit may be detected and used to provide active indication of whether the electronic device has been subjected to a substantial shock event. In addition, the shock sensor may be observed to passively determine whether the electronic device has been subjected to a substantial shock event.

Abstract translation: 本申请涉及安装在电子设备中的冲击传感器。 冲击传感器包括主动和被动冲击检测方法，其允许技术人员确定电子设备是否经受超过冲击阈值水平的冲击事件。 冲击传感器可以包括形成在没有超过冲击阈值水平的冲击事件的情况下保持打开的电路的冲击检测触点。 响应于显着的冲击事件，冲击传感器的可移动部件或物质可以从第一位置移动到第二位置，从而关闭由冲击检测触点形成的电路。 可以检测电路的变化并用于提供电子设备是否已经受到实质的冲击事件的主动指示。 此外，可以观察到冲击传感器被动地确定电子设备是否已经受到实质的冲击事件。
