IMPACT DETECTION METHOD AND APPARATUS

摘要

An impact detection apparatus (10), comprising: first and second electrical contacts (26a,26b; 30a,30b); and a detector (22) configured to detect bridging of the first and second contacts. The first and second electrical contacts (26a,26b; 30a,30b) are separated by a distance that is bridgeable by a predefined electrically conducting implement (16a; 16b), and the detector (22) is configured to detect the closing of a circuit upon any impact of the implement (16a; 16b) sufficient to bridge the first and second electrical contacts (26a,26b; 30a,30b) and to respond by outputting a signal indicative of the impact.
