Electronic security seal and system
First Claim
1. A tamper-proof electronic security seal which includes:
- a. a bolt and a locking element, said bolt having a head and a hollow shank extending therefrom having a longitudinal bore formed therein, said shank being dimensioned to pass through a lock hasp and having a free end formed for locking engagement with said locking element; and
b. an electronic seal element formed for mechanical connection to said bolt head, and including;
an electrical power source;
(ii) a control unit;
(iii) communications means responsive to said control unit; and
(iv) a sensor adapted for insertion into said longitudinal bore of said shank, and connected to said control unit;
wherein, in response to a severing of said shank and said sensor inserted therein, said control unit is operative to activate said communications means to emit an alarm signal;
wherein said communications means is ultrasonic communications means adapted to communicate with external ultrasonic communications means associated with a security system at a secured location; and
wherein said ultrasonic communications means is adapted to sense mechanical shock, thereby to function also as a means for sensing an attempt to mechanically tamper with said electronic seal element.

Abstract
A tamper-proof electronic security seal which includes a bolt and a locking element and an electronic seal element. The bolt has a head and a hollow shank extending therefrom having a longitudinal bore formed therein. The shank is dimensioned to pass through a lock hasp and has a free end formed for locking engagement with the locking element. The electronic seal element is formed for mechanical connection to the bolt head, and includes an electrical power source, a control unit, communications means responsive to the control unit and a sensor adapted for insertion into the longitudinal bore of the shank, and connected to the control unit. In response to a severing of the shank and the sensor inserted therein, the control unit is operative to activate the communications means to emit an alarm signal.
