Abstract
A system and device for providing bullet proof protection to persons is described. A pre-staged shield, possibly wall mounted, that is capable of shielding the head and torso, for example, may be provided in a vulnerable facility. An optional and distinct alert system may be activated when the shield is removed from its location, whether seated on the wall, mount, or container such as a storage locker. Such alert system may be triggered by a switch, such as a pressure sensing seat in communication with a loudspeaker and alarm or monitoring system. When an alarm is activated, an optional distinct alert is sounded within the facility and the monitoring system may alert law enforcement and emergency first responders of the active shooter location. Such a shield and system may permit an unarmed, unprepared person to have the opportunity to shield themselves.

DETAILED DESCRIPTION
(18) The present approach includes embodiments of a bullet proof shield that may be staged in vulnerable facilities where potential victims may gather. For example, a wall mounted shield may reduce the vulnerability of unarmed persons on the premises of a school or church. A pre-positioned bullet proof shield may be located consistently in a pre-determined, identifiable location that the potential victims may reach quickly.
(19) An embodiment of a shield may be mounted on a wall or other stand with an operable or electronic connection to a switch, such as a weight sensing switch, that may signal a monitoring system when the weight of a shield is lifted. Other types of switches, whether magnetic, resistance, etc., may also be used; for example, a reed switch. Such a switch is in operable communication with a primary alarm system adapted to communicate a shooter alert for alerting others to the presence of the shooter. In one embodiment, the shooter alert is an audible signal that will be distinct or uniquei.e., with distinct many a noise or signal that is separately identifiable from a fire or other conventional alarm.
(20) The audio alert is preferably designed to minimize the time needed for potential victims to react to the audio signal by having a high signal intensity and a frequency range that an ear is sensitive to, yet at the same time, is easily distinguishable from other conventional alarms. In one embodiment, the audio alert may be an audio signal having a frequency in between about 200 Hz and about 5000 Hz. In another embodiment, the audio alert may be a signal within a frequency range between about 500 Hz and about 3000 Hz. Certain embodiments may employ a frequency range below 1000 Hz, particularly for applications wherein the audio alert needs to travel longer distances. Standard fire alarm systems emit an alarm sound at a high frequency of 3100 Hz. Newer fire alarm systems utilize a low frequency alarm sound of 520 Hz. Thus, the frequency selected for the primary alarm system's audio alert is not equal to either the 3100 Hz or 520 Hz frequencies, and preferably, differs from either frequency by at least 100 Hz. The audio alert may be emitted at a signal intensity of between about 65 dB and about 120 dB. In certain embodiments, the audio alert may be emitted at a signal intensity of between about 80 dB and about 100 dB.
(21) Standard fire alarms employ a temporal-three alarm signal, often referred to as T-3 (ISO 8201 and ANSI/ASA S3.41 Temporal Pattern) and produces an interrupted four count (three half second pulses, followed by a one and one half second pause, repeated for a minimum of 180 seconds). Standard fire alarms emitting at 3100 Hz frequency use a sine waveform, while the 520 Hz frequency emitted from newer fire alarm systems uses a square waveform. In contrast, the audio alert of the primary alarm system may have an irregular waveform with a frequency that is not within a frequency range of an audio alarm of the secondary alarm system. One example of an audio alert may be a drum beat generated from an integrated circuit alarm device that communicates a threat of gunfire (e.g., Da-Da-Da-Dow). The drum beat may be in the form of a Morse code; for example, a drum beat having a Morse code pattern signaling S.O.S. Other examples of an audible signal include a loud shrill sound or an announcement that a shooter has been observed on the premises. This signal may be relayed to other Active Shooter Alert monitors. An Active Shooter Alert will allow persons located in the facility to immediately understand the situation and to take appropriate action.
(22) The optional alarm or alert circuitry may take a variety of forms. In one embodiment, it may be adapted from or incorporated into alarm circuits, using components such as an integrated circuit, NPN transistor, resistor, DC power source, and a pressure sensing switch instead of a heat or smoke sensing switch. The communications protocol for embodiments of the circuit may include interconnected alert and alarm condition sensors, processors, and monitors and signaling methods compatible with industry standards.
(23) Turning now to the drawings, in
(24) The primary alarm system 16 may also be interconnected with one or more secondary alarm systems. This interconnected system 16 may use a 3 wire or other conductor interconnect 18. As indicated briefly above this 3 wire connection provides main AC power via line 20 a neutral wire 22 and a single signal wire 14 that may be used to communicate an alarm condition to all units interconnected in the system 16. The signal generator 11 may be adapted to generate a secondary signal through the single signal wire to interconnected secondary alarm systems. These secondary alarm systems may include smoke or fire alarms, public announcement systems, and law enforcement. While this embodiment of system 16 is illustrated as having a particular configuration of distributed sensors 10, one skilled in the art will recognize that such a system 16 illustrated in
(25) Recognizing that several types and configurations of distributed sensing and detector systems may exist using the standard 3 wire interconnect 18, it is preferable that the protocol of the present approach may be backward compatible with prior interconnect systems to permit retrofitting. Specifically, the protocol may be capable of providing an indication of existing smoke and fire sensors that they will recognize and process as a fire alarm when smoke or fire is indicated. Likewise, the protocol may also be capable of providing an audio alert when a shield is unseated for protection of unarmed persons from an active shooter.

(27)
(28)
(29) To halt an alert signal, a removal or disconnect of AC power source 40 may permit a reset of the shooter alert signal and allow for the shields to be replaced on the switch 10, opening the DC power line. Integrated circuit chip 50 may be a Programmable Read-Only Memory (PROM) chip designed to generate a drumbeat alert signal that can be developed across a 200 ohm resistor through NPN transistor 52 and applied as an audio drumbeat signal at junction 14 to speakers and interconnect the signals to monitors.
(30) The audio alert may be sent to the speaker as a PCM signal 100.
(31)
(32) Cost of bullet proof materials can be high, and such facilities may lack funding for implementation. Of course, the saving of a single life may justify use of the present approach. However, it is considered that the present approach may be modified or tailored to reduce the cost of implementation.
(33) The personal shield and alarm system described herein may also be adapted for home and private use. Such use may also involve interconnection with an alarm and alert system and would be optional depending upon the user's requirements. Public or private use may involve an interconnected alarm and alert system triggered by a switch.
(34) Shields of the present approach may be manufactured from any one material selected from of an assortment of materialssuch as transparent polymers, acrylic, poly-paraphenylene terephthalamide (available under the Kevlar brand name from DuPont), ceramics, or solid metals. The difference in the material may be selected by the user for their more specific purposes. A transparent or partially transparent polymer may be used if it is desired that a user may keep visual track of the shooter, depending on the sizing of the shield. A metal shield, for example, may be used if the intent is that a user simply exit the area of the shooter to the nearest safe spot. Either choice is better than remaining unprotected.
(35) Other sample bullet-resistant materials (also called ballistic materials or, equivalently, anti-ballistic materials) such as Ultra High Molecular Weight Polyethylene (UHMWPE), polycarbonates, or carbon fiber composite materials, or a material may be basic and simple, such as steel or titanium.
(36) The shield may include one or more handles accessible from the rear face of the shield to enable an individual to hold the shield in front and carry it while maneuvering. Each handle may be affixed to the rear face and have a length greater than its width and adapted to being encircled by an individual's hand in a power grip whereby the fingers wrap around the handle in one direction and the thumb may wrap around the handle in the other direction, the length of each handle parallel to the rear face of the shield. In some embodiments, the handles are ambidextrous to allow a user to grasp with either hand. The handles may be designed to have large contact services to distribute the force over a larger area and to direct it to less-sensitive areas, such as the tough tissue between the thumb and index finger. The handle may omit finger grooves or other recess to enable a large variety of hand sizes to grasp the handle.
