Method and apparatus for detecting unauthorized intrusion into a container
First Claim
1. A method comprising:
- emitting a wireless signal within a container;
detecting said wireless signal in the region of and externally of said container;
monitoring said detected wireless signal for a change in a characteristic thereof caused by a circumstance other than a change in said wireless signal as transmitted; and
responding to detection of a change in said characteristic of said detected wireless signal by transmitting a wireless notification of the occurrence of the change to a location remote from said container.

Abstract
An intrusion detection technique involves: emitting a wireless signal within a container; detecting the wireless signal near the container; and responding to detection of a change in a characteristic of the detected wireless signal by transmitting a wireless notification to a location remote from the container. A different technique involves: responding to a determination that a condition representative of unauthorized intrusion is present while the container is stationary by transmitting a wireless notification; and responding to a determination that the container is moving by ignoring whether the condition is present. Yet another technique involves: monitoring whether a door of a container is in a closed position; and emitting a wireless signal indicating whether the container door is in the closed position.

15. An apparatus comprising:
-
a container; a first transmitter which is supported on said container and emits a wireless signal within said container; a receiver which is supported on said container externally thereof, which detects maid wireless signal, and which monitors said detected wireless signal for a change in a characteristic thereof caused by a circumstance other than a change in said wireless signal as transmitted; and a second transmitter which responds to detection by said receiver of a change in said characteristic of said detected wireless signal by transmitting a wireless notification of the occurrence of the change to a location remote from said container. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

35. An apparatus comprising:
-
a container; a first portion which monitors said container for a condition representative of unauthorized intrusion into the container; a second position which determines whether said container is stationary; and a third portion which is cooperable with said first and second portions, which responds to a determination that said condition is present while said container is stationary by transmitting a wireless notification of the presence of said condition, and which responds to a determination that said container is moving by ignoring whether said condition is present. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43)

44. An apparatus comprising:
-
a container having a door supported for movement to and from a closed position; a first portion which monitors whether said door of said container is in said closed position; and a second portion which is cooperable with said first portion and which can emit a wireless signal indicating whether said container door is in said closed position; wherein said first portion carries out said monitoring of said door from within said container, and includes a detector that is supported on said door; and wherein said second portion is supported on said door and effects said emission of said wireless signal at a location external to said container. - View Dependent Claims (45, 46, 47)

48. A method comprising:
-
emitting a wireless signal within a container; detecting said wireless signal at each of spaced first and second locations in the region of said container; monitoring said detected wireless signal for a change in a characteristic thereof, said characteristic being a phase difference between said wireless signal as detected at said first location and said wireless signal as detected at said second location; and responding to detection of a change in said characteristic of said detected wireless signal by transmitting a wireless notification of the occurrence of the change to a location remote from said container. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55)
