Abstract
Abstract An alarm-security system for maintaining surveillance of an individual. When unauthorized departure of an individual from a defined secure area is detected, the alarm-security system generates departure signals which are transmitted to a control center where alarm signals are initiated. In one embodiment of the system an alarm-secure band is carried on the person and cannot be removed from the person without generating alarm signals.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
169 words
A surveillance alarm-security system for detecting unauthorized departure of a person from a defined secure area in a building structure, for generating and transmitting signals responsive to such departure, and for activating security systems in response to such departure, said system comprising a. an alarm-secure band carried on the person and including (i) at least one loop around a portion of the body of the person, (ii) means for generating a secure signal, and (iii) means for generating an alarm signal responsive to removal of said band from the person; b. means carried on the person for transmitting said secure and alarm signals; and, c. means in said building structure for receiving said secure and alarm signals and for generating security system activation signals in response thereto; said alarm signal means comprising at least one structural moment detector, said structural moment detector generating signals responsive to deflection of said band induced by the removal of said band from the person and being insensitive to linear distortion of said band.
Claim 2
Dependent Claim
169 words
A surveillance alarm-security system for detecting unauthorized departure of a person from a defined secure area in a building structure, for generating and transmitting signals responsive to such departure, and for activating security systems in response to such departure, said system comprising a. an alarm-secure band carried on the person and including (i) at least one loop around a portion of the body of the person, (ii) means for generating a secure signal, and (iii) means for generating an alarm signal responsive to removal of said band from the person; b. means carried on the person for transmitting said secure and alarm signals; and, c. means in said building structure for receiving said secure and alarm signals and for generating security system activation signals in response thereto; said alarm signal means comprising at least one structural moment detector, said structural moment detector generating signals responsive to deflection of said band induced by the removal of said band from the person and being insensitive to linear distortion of said band.
Claim 3
Dependent Claim
158 words
A surveillance alarm-security system for detecting unauthorized departure of a person from a defined secure area in a building structure, for generating and transmitting signals response to such departure, and for activating security systems in response to such departure, said system comprising a. an alarm-secure band carried on the person and including (i) at least one loop around a portion of the body of the person, (ii) means for generating a secure signal, and (iii) means for generating an alarm signal responsive to removal of said band from the person; b. means carried on the person for transmitting said secure and alarm signals; and, c. means in said building structure for receiving said secure and alarm signals and for generating security system activation signals in response thereto; said alarm signal means comprising strain gauge means, said strain gauge means generating signals responsive to linear distortion of said band induced by the removal of said band from said person.
Claim 4
Dependent Claim
158 words
A surveillance alarm-security system for detecting unauthorized departure of a person from a defined secure area in a building structure, for generating and transmitting signals response to such departure, and for activating security systems in response to such departure, said system comprising a. an alarm-secure band carried on the person and including (i) at least one loop around a portion of the body of the person, (ii) means for generating a secure signal, and (iii) means for generating an alarm signal responsive to removal of said band from the person; b. means carried on the person for transmitting said secure and alarm signals; and, c. means in said building structure for receiving said secure and alarm signals and for generating security system activation signals in response thereto; said alarm signal means comprising strain gauge means, said strain gauge means generating signals responsive to linear distortion of said band induced by the removal of said band from said person.
