    • An electronic security system (10) includes an electronic lock device (12) and an associated electronic key (14). The electronic lock device includes a number of operational features, such as counters to monitor usage. The electronic key (14) also includes a number of operational features, such as packet-formatted audio download of key data using a piezoelectric transducer (150); codes that can be updated early without invalidating existing codes; and a tracking memory (148) that identifies the lock devices with which the key has communicated. When this tracking memory becomes full, operation of the key may be impaired. The impaired key can then only be re-enabled by downloading the tracking data from the key memory. The lock and key units cooperate to provide still additional operational features, such as a selectively-enabled, vandalism-resistant lockout list; a secure challenge-response security mechanism; and bilateral data/power exchange between the two units using just a single pair of conductors.
    • 电子安全系统(10)包括电子锁装置(12)和相关电子钥匙(14)。 电子锁装置包括许多操作特征,例如用于监视使用的计数器。 电子钥匙(14)还包括许多操作特征,诸如使用压电换能器(150)的密钥数据的分组格式音频下载; 可以提前更新而不使现有代码无效的代码; 以及跟踪存储器(148),其识别密钥与之通信的锁定装置。 当该跟踪存储器变满时,键的操作可能受损。 然后只能通过从密钥存储器下载跟踪数据来重新启用受损密钥。 锁和关键单元合作以提供仍然附加的操作特征,例如有选择地启用的破坏性破坏的锁定列表; 安全的挑战应对安全机制; 并且两个单元之间的双向数据/电力交换仅使用一对导线。
