Alarm system for sensing and vocally warning of an unauthorized approach towards a protected object or zone
First Claim
1. A vocal alarm system coupled to an object to be protected, said alarm system comprising:
- means for generating a radio frequency (RF) field within a protected area surrounding said object or zone;
means for sensing an interference within said RF field of the type created by entry of a person within said RF field;
synthetic voice generation means for generating a first vocal warning in response to the sensing of an interference within said RF field, said vocal warning providing audible instructions that alert the person that he or she has entered a protected are and that he or she must exit or leave the protected area in order to prevent an alarm from sounding; and
alarm generation means responsive to said sensing means for sounding an alarm in the event the person has not left the protected area, as detected by said sensing means, within a specified time period subsequent to first sensing an interference within said RF field.

Abstract
An alarm system detects an unauthorized approach towards a protected object, such as an automobile, and provides verbal warnings to the person approaching the object, that he or she must move away from the object or an alarm will be triggered. The alarm system includes a proximity detector to detect an intrusion into an adjustable electromagnetic field set up around the object and means for generating vocal signals using synthetic speech generation circuits. Such vocal signals instruct the intruder to back away from the protected object before the alarm is triggered, thereby preventing the intruder from inflicting any damage to the object; and draw attention to the fact that an unauthorized penetration or entry event has occurred in the event the alarm is triggered. The user may select various operating modes and performance options in how the system is used.

10. A method of protecting an object or zone using a vocal alarm system having synthetic speech generation means and radio frequency (RD) generation and sensing means, said method comprising the steps of:
-
(a) generating an (RF) field using said RF generation means within an area to be protected surrounding said object or zone; (b) sensing variations in the strength of said RF field of the type created by entry of a large body mass, such as a person, into said RF field; (c) generating a first vocal warning in response to the sensing of a variation in said RF field in step (b), said vocal warning providing audible instructions that alert any person who may have entered the RF field that he or she has entered a protected area and that he or she must leave the protected area immediately in order to prevent an alarm from sounding; and (d) sounding an alarm in the event the person has not left the protected area surrounding said object within a specified time period subsequent to first sensing a variation within said RF field. - View Dependent Claims (11, 12)

13. A method of protecting an object from unauthorized tamper or entry comprising:
-
defining an area surrounding said object; sensing any entry of a person into said defined area; and warning said person using synthetically generated speech that he or she is too close to the object and instructing the person to move back away from the object or else an alarm will sound; whereby the object is protected by preventing a person from getting too close to the object. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. Apparatus for protecting an object from being touched by a human intruder comprising
means for generating an invisible field around said object; -
means for sensing the entry of a human into said invisible field; audible alarm means for sounding an audible alarm; means for electronically issuing a synthetic speech message responsive to the sensing of a human within said invisible field, instructing said person to leave said field or said audible alarm means will be triggered; and means for sounding said audible alarm means with said synthetic speech message generation means in the event a human remains within said field of a prescribed time period after said synthetic speech message is issued. - View Dependent Claims (23)
