Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
An alarm device adapted to be fixed to an article, for giving an alarm in response to unauthorized movement of the article, the alarm device comprising: motion detection means; means for producing an alarm; logic and timing means, responsive to said motion detection means, for causing said alarm means to produce an alarm only if: (a) the motion detection means detects an initial motion; and (b) the motion detection means detects a predefined pattern of continual motion following said initial motion, and means for reducing the electrical current demand of said logic and timing means if no motion is detected by said detection means within a predetermined interval following detection of said initial motion.
Claim 2
Dependent Claim
114 words
An alarm device adapted to be fixed to an article, for giving an alarm in response to unauthorized movement of the article, the alarm device comprising: motion detection means; means for producing an alarm; logic and timing means, responsive to said motion detection means, for causing said alarm means to produce an alarm only if: (a) the motion detection means detects an initial motion; and (b) the motion detection means detects a predefined pattern of continual motion following said initial motion, and means for reducing the electrical current demand of said logic and timing means if no motion is detected by said detection means within a predetermined interval following detection of said initial motion.
Claim 3
Dependent Claim
86 words
An alarm device adapted to be fixed to an article, for giving an alarm in response to unauthorized movement of the article, the alarm device comprising: motion detection means; means for producing an alarm; and logic and timing means, responsive to said motion detection means, for causing said alarm means to produce an alarm only if: (a) the motion detection means detects an initial motion; and (b) the motion detection means detects motion in each of a plurality of predetermined successive intervals following said initial motion.
Claim 4
Dependent Claim
86 words
An alarm device adapted to be fixed to an article, for giving an alarm in response to unauthorized movement of the article, the alarm device comprising: motion detection means; means for producing an alarm; and logic and timing means, responsive to said motion detection means, for causing said alarm means to produce an alarm only if: (a) the motion detection means detects an initial motion; and (b) the motion detection means detects motion in each of a plurality of predetermined successive intervals following said initial motion.
Claim 5
Dependent Claim
32 words
An alarm device according to claim 2 including means for resetting said logic and timing means when, in any of said predetermined successive intervals, the motion detection means does not detect motion.
Claim 6
Dependent Claim
40 words
An alarm device according to claim 2 including means for reducing the electrical current demand of said logic and timing means if no motion is detected by said detection means within a predetermined interval following detection of said initial motion.
Claim 7
Dependent Claim
25 words
An alarm device according to claim 2 including means for adjusting the number of said predetermined successive intervals in said plurality of predetermined successive intervals.
Claim 8
Dependent Claim
162 words
An alarm device adapted to be fixed to an article, for giving an alarm in response to unauthorized movement of the article, the alarm device comprising: motion detection means; means for producing an alarm; timing means for establishing a first predetermined interval and a second predetermined interval, the second predetermined interval consisting of a succession of predetermined sub-intervals, and for causing said alarm producing means to produce an alarm following the end of said second predetermined interval; and logic means, responsive to said motion detection means, for controlling said timing means so that the timing means begins said first predetermined interval after detecting an initial motion, initiates said second predetermined interval upon detecting additional motion within said first predetermined interval, and produces said alarm only if: (a) the motion detection means detects said initial motion; and (b) the motion detection means detects additional motion during said first predetermined interval; and (c) the motion detection means detects motion in each of said sub-intervals.
Claim 9
Dependent Claim
162 words
An alarm device adapted to be fixed to an article, for giving an alarm in response to unauthorized movement of the article, the alarm device comprising: motion detection means; means for producing an alarm; timing means for establishing a first predetermined interval and a second predetermined interval, the second predetermined interval consisting of a succession of predetermined sub-intervals, and for causing said alarm producing means to produce an alarm following the end of said second predetermined interval; and logic means, responsive to said motion detection means, for controlling said timing means so that the timing means begins said first predetermined interval after detecting an initial motion, initiates said second predetermined interval upon detecting additional motion within said first predetermined interval, and produces said alarm only if: (a) the motion detection means detects said initial motion; and (b) the motion detection means detects additional motion during said first predetermined interval; and (c) the motion detection means detects motion in each of said sub-intervals.
Claim 10
Dependent Claim
45 words
An alarm device according to claim 6 including means for resetting said timing means when the motion detection means does not detect motion in said first predetermined interval and when, in any of said predetermined successive intervals, the motion detection means does not detect motion.
Claim 11
Dependent Claim
36 words
An alarm device according to claim 6 including means for reducing the electrical current demand of said logic means and timing means when the motion detection means does not detect motion in said first predetermined interval.
Claim 12
Dependent Claim
22 words
An alarm device according to claim 6 including means for adjusting the number of said sub-intervals which constitute said second predetermined interval.
