Description

System and Method for Combating Barricaded Opposition TECHNOLOGICAL FIELD The present disclosure concerns a warfare system and method. More specifically it concerns a system and method for Combating Opposition that is Barricaded in a Fortification.

BACKGROUND It is well known that acoustic noise/noises and signals can affect the human brain casing discomfort, pain and anxiety. Exposure to loud or persistent noise (and both) can cause discomfort and pain by damaging hearing, inducing stress, disrupting sleep, and potentially leading to conditions like tinnitus and hyperacusis. Loud sounds can cause immediate physical discomfort, while prolonged exposure can lead to long-term hearing damage. Additionally, certain frequencies and patterns of sound can cause psychological distress, affect cognitive function, and even lead to physiological reactions like increased heart rate and blood pressure, negatively impacting overall health and well-being.

GENERAL DESCRIPTION Being exposed to these extreme loud and persistent irritating noise signals will defiantly cause distress, pain, anxiety, vertigo, dizziness, vomiting and even fainting. It has been realized, in accordance with this disclosure, that a device and a method involving the creation of such extreme exposure can be used as a weapon against individuals, that are barricaded within a fortification. Such individuals will be referred to herein as "opposition" and include enemy soldiers, terrorists, rioters, rioting prison inmates, individuals who unlawfully entered a building, etc. Provided by one aspect of this disclosure is a system for delivering harming energy to opposition barricaded in a structure, comprising (i) at least one transducer configured for transducing and transmitting elastic waves or sound signals directly (namely not through the air medium) to a structure element of said structure and (ii) a control utility coupled to said at least one transducer configured for controlling the transducer to cause it to deliver such vibrations leading to a damaging sound within said fortification. Also provided by another aspect of this disclosure is method for harming opposition barricaded in a fortification, comprising transmitting vibrations directly to a structure element of said structure and controlling the vibrations such that their parameters yield damaging sound within said fortification. The term "damaging sound" may include any sound which has a negative psychological or physiological effect on the opposition. These effects may include distress, pain, anxiety, irritation despair, vertigo, dizziness, vomiting and even fainting. Sound is a mechanical energy transmitted through a solid medium, such as concrete, in the form of elastic waves. Elastic waves in a solid medium involve movements both parallel and perpendicular to the direction of wave propagation. This mechanical energy propagates relatively efficiently, with considerably less attenuation than when traveling through air, for example, and the vibrations can induce a sound that can be heard by the opposition even if remotely located from the sound origin. Elastic waves in a solid medium such as concrete can also carry a wide range of frequencies, although that due to the medium's density, low-frequency vibrations tend to propagate more efficiently. The at least one sound transducer is a device that can introduce vibration into a solid structure. It may comprise a mechanical actuator or motor configured for converting energy into mechanical vibrations and is configured for transferring such vibrations to the structure element, for example through a mechanical coupling arrangement for transferring it to the structure element. In some embodiments the system comprises one such sound transducer. In other embodiments two or more transducers may be employed, which may be the same or different. In the case of a plurality of transducers, all may be configured to transmit the same vibrations to the structure, for example at different locations, or one or more of such transducers may be adapted or intended to transmit vibrations to the structure of different characteristics than other. By embodiment the structure is an above-ground installation such as a building, a fortification, a prison, etc. By another embodiment the structure is an underground construction such as a tunnel.

The parameters of sound that may be controlled include intensity, pitch, temporal modulation, etc. The sound transmitter may be selected from vibrating-knocking devices that may be attached directly to concrete element such as a wall, ceiling, floor or column of a foundation elements of an above-ground structure, or an outer extension or pier of an underground structure. Vibrating-knocking devices and sound transmitters through solid structures can produce vibrations and sound waves along the complete elastic and acoustic spectrum, from very low frequencies to very high, e.g., from INFRASOUND to and include ULTRASOUND. Examples of sound transmitters include vibrating motors of various kinds with a probe coupled to the motor that can be associated with s structure elements.

DETAILED DESCRIPTION OF EMBODIMENTS Exemplary parts of the system include: a. Vibrating motor Specially configured vibrating motor may, for example, be one of the following: 1. Eccentric Rotating Mass (ERM) Vibrators: These are the most common type of vibrating motors, often found in mobile phones and game controllers. They consist of an unbalanced mass attached to a motor shaft. As the motor rotates, the centrifugal force of the unbalanced mass creates vibration. 2. Linear Resonant Actuators (LRAs): LRAs use a small internal mass attached to a spring, which is driven back and forth. They are used in applications where precise control of vibration is needed, such as haptic feedback in touchscreens and wearables. 3. Coin Vibrators: These are a type of ERM motor but in a compact, flat form factor resembling a coin. These are commonly used in wearable devices due to their small size. 4. Brushless Vibration Motors: Unlike traditional brushed motors, brushless vibration motors have a longer lifespan and can be controlled more precisely. They are used in advanced haptic applications.

. Industrial Vibrating Motors: These are heavy-duty motors used in industrial applications like conveyors, feeders, screens, and vibrating tables. They are designed to handle large loads and tough environments. 6. Piezoelectric Actuators: These devices use the piezoelectric effect to create vibration. They are highly precise and used in applications requiring fine control, such as medical devices and precision machinery. 7. Pneumatic Vibrators: These utilize compressed air to generate vibration and are often used in industrial applications for material handling and flow assistance. 8. Electromagnetic Vibrators: These generate vibrations using electromagnetic forces and are used in various applications, from industrial feeders to consumer electronics. Each type of vibrator has its unique characteristics, advantages, and applications. The choice of a vibrating motor or device depends on factors like required vibration strength, precision, size constraints, power consumption, and the specific use case. Machines designed for rapid, repetitive hammering or pounding action may also be use. Such machines come in various forms, each tailored for specific tasks. Some examples: 1. Hammer Drill: Designed for drilling into hard materials like concrete or masonry, hammer drills use a percussive action that hammers and drills simultaneously. They are equipped with a clutch that allows them to switch between drilling and hammering modes. 2. Rotary Hammer: More powerful than standard hammer drills, rotary hammers use a piston mechanism instead of a special clutch to deliver a more powerful hammering action. They are used for more demanding tasks, such as drilling into tougher materials like reinforced concrete. 3. Impact Driver: Primarily used for driving screws, bolts, and fastening materials together, impact drivers provide a high-torque hammering action. This action is used to drive fasteners with more force than a standard drill, making it ideal for construction and heavy-duty tasks. 4. Jackhammer (Pneumatic Drill): These are heavy-duty tools used for breaking up concrete and pavement in construction and demolition. They use compressed air or hydraulic power to drive a hammering piston.

. Pile Driver: Used in construction to drive piles into soil to provide foundation support for buildings or other structures, pile drivers use a heavy weight dropped onto a pile to drive it into the ground. 6. Stamping Press: In industrial manufacturing, stamping presses use a hammering action to shape or cut metal into specific forms. They are essential in automotive manufacturing, metalworking, and fabrication. 7. Forging Hammer: Used for shaping metal in blacksmithing and industrial forging, these hammers repeatedly strike hot metal to form it into a desired shape. 8. Vibratory Pile Hammer: Unlike traditional pile drivers, vibratory hammers use rapid vibrations to sink piles into soft soil. They are particularly useful in environments where traditional pile driving is ineffective or could cause too much disturbance. Hammer drill or rotary hammer may be particularly suitable for some embodiments of this disclosure. b. Control utility:The control utility is coupled to the motor for controlling the frequency of the vibrations in a manner that the vibrations will be as irritating as possible while propagating to large distances. Varying the speed of electrical motors can be achieved through several methods, each suitable for different types of motors and applications: 1. Variable Frequency Drives (VFDs): VFDs are used primarily with AC motors, especially three-phase induction motors. They work by varying the frequency and voltage supplied to the motor, allowing precise speed control. VFDs are efficient and widely used in industrial applications . 2. Pulse Width Modulation (PWM): PWM controls the speed of DC motors by varying the voltage applied to the motor through a series of on/off pulses. This method is efficient and provides fine control over motor speed. 3. Resistive Throttle Control: This method, often used in older or simpler DC motor systems, varies the speed by changing the resistance in the motor circuit, thereby adjusting the voltage across the motor. 4. Voltage Variation: For both AC and DC motors, varying the supply voltage can change the speed. However, this method is less efficient and can affect the motor's torque and performance . 5. Gear Reduction: Using gears or a gearbox can mechanically reduce the speed of a motor. This method doesn't change the motor's actual speed but reduces the output speed while increasing torque. 6. Slip Control (for AC Induction Motors): By adjusting the slip of an induction motor (the difference between the rotor's speed and the motor's magnetic field speed), the output speed can be varied. This is less common and typically less efficient . 7. Field Current Control (for DC Motors): In DC motors, especially series and shunt motors, the speed can be controlled by varying the current in the field winding. This method changes the motor's magnetic field strength, thereby affecting its speed. 8. Ward-Leonard Control: This is an older method used for controlling the speed of DC motors. It involves a motor-generator set where the generator's output voltage, which powers the DC motor, is varied to control the speed. Each of these methods has its advantages and limitations, and the choice depends on factors like the type of motor, required speed range, desired control accuracy, efficiency, cost, and application. The VFDs may be particularly suitable for some embodiments of this disclosure.
