First Claim
Patent Images
1. A tamper-resistant remotely monitorable electronic seal comprising:
- a shaft portion, comprising an inductor;
a sensor;
a socket, comprising a transponder, said socket being arranged to engage said shaft portion and said sensor in a monitorable manner; and
a wireless communicator associated with at least one of said shaft portion, said sensor and said socket and being operative to provide a remotely monitorable indication of at least one monitorable event,said sensor being operative to sense application of force to said electronic seal in an attempt to separate said shaft portion from said socket and to indicate said application of force as one of said at least one monitorable event, andsaid transponder being operative to transmit information relating to said socket, via said inductor, to said wireless communicator.

16. A tamper-resistant remotely monitorable electronic seal comprising:
-
a shaft portion including at least one conductor; a sensor; a socket, arranged to engage said shaft portion and said sensor in a monitorable manner; a wireless communicator associated with at least one of said shaft portion, said sensor and said socket and being operative to provide a remotely monitorable indication of at least one monitorable event; at least one propinquity switch, which is associated with said at least one conductor and which is operated by an actuator associated with said socket, said sensor being operative to sense application of force to said electronic seal in an attempt to separate said shaft portion from said socket and to indicate said application of force as one of said at least one monitorable event, said at least one conductor being interrupted in response to disengagement of said shaft portion and said sensor, wherein said disengagement results in one of said at least one monitorable event, and said propinquity switch being opened in response to said shaft portion being separated from said socket, thereby braking at least one conductive path and producing one of said at least one monitorable event. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
