Bolt Security Seal with Reusable Electronics Module and Bolt
First Claim
1. An electronic security bolt seal with a reusable electronics module for locking a hasp comprising:
- an electronic module comprising a housing having a cavity and a electronic circuit in the cavity for sensing and transmitting the tamper state of the seal;
a bolt having a head and an elongated shank engaged with the housing cavity and engaged with the electronic circuit, the bolt being arranged for completing the engaged circuit and for engaging the hasp to be locked; and
a bolt locking device engaged with and locked to the bolt external the module to secure the module to the bolt in the locked state, the circuit for sensing the integrity of the engaged locked bolt manifesting the seal tamper state, at least the locked bolt having an exposed region external the module for selective opening of the bolt to unlock the seal from the hasp and release the module from the bolt for subsequent reuse of the module.

Abstract
An electronic circuit senses and transmits a tamper condition of a bolt seal locked with a locking device external the module on a side of the module opposite the bolt head. The module is reusable intact when the bolt/locking device, which is conventional, is opened. In various embodiments, a tang type metal/plastic or plastic tamper indicative seal may be attached through a hole in the bolt tip region that has a narrowed diameter tip or attached in a one way clutch action on the tip, or which mates in a bolt groove at the bolt tip region and/or a conventional tamper evident seal is attached to the surface of the bolt shank at the bolt tip region in a clutch action. Different bolt embodiments comprise non-electrically conductive or electrically conductive plastic or steel shanks with juxtaposed electrical conductors along the shank connected to external conductors formed by coatings or axially spaced cylindrical sleeves forming contact regions which engage the circuitry contacts inside the module.
