The present disclosure is in the field of electro mechanical pest repellents.
Pests come in various types and sizes. Pests may include insects, animals, birds and in some cases children or people in unwanted areas of yards or houses or any other building. Fences, chemicals and other means used to control or kill pests are often dangerous or cumbersome to humans.
Today many new insects have invaded areas not formally inhabited by their species. Some US insects like Japanese beetles, Box Elders bugs, mosquitoes and ants are often difficult at best to control with pesticides. They have become a plague in many areas and are spreading rapidly. They often invade fruits and vegetable plants that are difficult to spray with chemicals, especially close to harvest time. Some insects often sit on the warm sides of houses or structures and plants and gravitate to warm openings in fall. With the advent and growth of organic gardening, pesticide use may be prevented all together.
Pests are not limited to insects. Chemicals may not be effective against some pests such as birds (robins) who eat cherries out of cherry trees as they ripen. Birds often find favorite places to perch that are destructive to the items being perched on. Destructive and dangerous places to perch include power lines and other places where the birds may interrupt service. Often birds leave fecal matter in all sorts of places where they perch that destroy the esthetic look of the place where perched. Some examples of common places soiled by birds include windows, doors, mail boxes, lights, landscaping lights, fences, antennas, cars, etc. Birds eat fish from Koi ponds. Dogs often wander into bushes and landscaping areas. Some animals like mice often find favorite hiding places or digging places near houses or other unwanted areas. Deer often jump over fences and eat various plants.
Many of these common pests have built in fight or flight mechanisms which are triggered by their sense of touch. Vibrations, transmitted through hands, feet, claws. Legs, antenna, air etc. are used to indicate a predator is nearby. These vibrations or movements often trigger the fight or flight mechanism in these pests.
The present disclosure is related to an apparatus and method to intelligently generate and control a mechanical vibration or sway in a surface or object to modify behavior of pests. An exemplary embodiment may be a stand-alone device that transfers movement and/or vibrations to a surface or object that is desired to be kept pest free. Other embodiments may adjust vibration or sway characteristics including, but not limited to, vibration amplitude in 1 or 3 axis of vibration, frequency, period, or vibration slope, vibration acceleration, direction of applied vibration (force), sway, and/or resonant/optimum frequency.
In exemplary embodiments, the force vectors may be directional and therefore can be made more effective when the axis of the generated vibration is modified or optimized.
In a non-limiting embodiment used in connection with a tree branch, tree branches may act as dampeners. When vibrations are applied down a branch, the branch begins to sway as the dampening anchors of the tree roots have less effect on outward branches. Non-limiting embodiments may include vibration feedback monitoring, making it possible to consider and adjust both the branch sway and the resonant point at which vibrations are maximized.
Embodiments disclosed herein adjust additional characteristics of vibration of a surface or object, and an impart sway on some surfaces or objects.
Embodiments as disclosed herein may monitor parameters related to the vibration of sway of the object or surface in real time to provide automatic corrective action to a vibration signal.
Embodiments as disclosed herein may further monitor many other parameters including, but not limited to, date, time, season, weather, temperature or ambient light and provide automatic corrective or alternative action to the vibration and sway characteristics. This enables the device to compensate, alter, proportion or eliminate vibrations based on the parameters.
Exemplary embodiments may be used on advanced methods as disclosed herein of determining when vibration is to be applied to an object or surface. In a non-limiting example, a device might vibrate for 5 seconds and then the next vibration is actually determined by the next time temperature passes a certain set point. In addition to being used for compensation purposes, parameters may be used to advance to the next vibration stage rather than time.
While the embodiment described herein utilizes a vibration motor 14 shown in
Embodiments disclosed herein may be used in combination or integrally combined with other existing objects. An example that utilizes that embodiment might include a mailbox with vibrating mechanism that vibrates when touched in order to keep birds from defecating. Another embodiment incorporates a vibrating mechanism incorporated into common landscaping lights to keep birds from defecating by sensing the vibrations from a bird landing on the light using an accelerometer. Advanced embodiments may take advantage that the vibration caused by an animal moving actually causes the motor to rotate slightly causing the motor to act briefly as a generator and an advanced controller detects the generated voltage from the mechanical motion to sense movement. Other embodiments would incorporate the device into common materials used in construction or housing (windows, doors, and siding) to repel harmful or annoying pests.
Referring back to
The information provided to the CPU (not depicted) from these environmental sensors enable more advanced control of the motor and eccentric weight than a simple on/off switch control would. Embodiments of this device incorporate a sensor or parameter to control the characteristics of vibrations or to start and stop modes of vibration. Embodiments may also include an ability to respond to the parameters listed along with the ability to control a series of vibration events in response to at least one sensed environmental parameter. By using an advanced microcontroller with flash memory, a variety of parameters may trigger the modes of vibration or compensate the level of vibrations.
Various techniques in the embodiments to conserve power for battery operation may be employed. This first technique used in this embodiment is Pulse width modulation. The enables the vibration generator to operate off of rated battery voltage and thus get maximum vibrations. It also enables the generator to operate at less than its rating to reduce power consumption and control vibration level. Reduction of the control signal enables lesser vibrations to adjust for other pests and conditions. The second technique employed here to conserve power is to turn the motor on and off thus maximizing torque at startup yet minimizing average drain on the battery when off. Software and hardware controlled profiles regulate power consumption. Battery monitoring circuitry is also employed to regulate power consumption providing feedback. Power conservation also employs the use of standby or sleep modes of the microcontroller to keep some operating circuitry powered but in very low standby current mode when the device is not vibrating. The light sensor is used to control profile steps for operation only at night or day or in sunny or cloudy conditions. This maximizes effectiveness and yet at the same time, it manages power consumption.
This embodiment utilizes a voltage regulator and switching circuit to apply voltage to the motor. This voltage is limited to not exceed rated voltage of the motor.
The main control board has an external connector in this embodiment. This connector is used to power and control the device for applications where the application desires longer term operation than can be achieved using the on board batteries. An item such as a large battery may then be operatively coupled to many devices to operate a network of devices. These devices may then be controlled by the internal control board or controlled by an external source. They may also be powered by the internal source or by the external source. Other embodiments consist of a controller which controls many of the devices but with the same functions built into this embodiment of the controller.
Other embodiments used to generate movement might utilize AC motors, Weights which drop utilizing gravity to generate movement, devices which tap, moving air, wind to generate vibrations, devices which pull or push on surfaces, and water pulses to generate vibrations.
The vibration generator is controlled by a microcontroller 24 (
In this embodiment, the main controller board 22 utilizes a microcontroller 24 with operating software that is stored in flash memory 28 in this embodiment. This flash memory 28 is also used to hold various setting or values for controlling vibration parameters. Flash program memory 28 may be complemented by flash data memory 28 to allow for storage of user generated operating profiles. Flash program memory may also be incorporated directly into the microcontroller. The microcontroller 24 has external connection ability through the I/O 46 to allow for the operating system or other software or firmware to be changed or updated. In this embodiment that circuitry includes a USB interface. The microcontroller 24 may include very low power operating modes to enable very low power operation at all times to conserve power. The microcontroller 24 executes computer readable programs or code to carry out the software functions shown in the flow charts of
This embodiment incorporates an accelerometer 40. This enables the apparatus to measure the vibrations imparted to the object or surface to enable corrective action. The accelerometer measures acceleration in the X, Y, and Z plains. This feedback is used to calibrate the apparatus to its surroundings and also to make corrective action. This accelerometer may also be used as a trigger as to when to vibrate and if to vibrate. In extensive monitoring of some pests they do not move or do no come out during windy conditions. The software executed by the CPU can use this signal to change operation if windy conditions are detected or if pest-caused vibrations are detected. Since the apparatus is secured to the object or surface, the accelerometer measures the movement (vibration or sway) of the surface or object rather than the operation of the vibration generator. This enables corrective action in response to measurements to operate the vibration generator to create a targeted vibration or sway on the surface or object. Other methods of getting feedback are to monitor the motor current and/or voltage in this embodiment. All devices known to this inventor vibrate at an expected level but do not incorporate feed-back to verify that the imparted vibration occurs at the expected. The use of feedback of the accelerometer and other feedback signals such as light give this invention the ability to provide a continuously changing vibration based on feedback. The accelerometer may detect movement and thus vibrate when the plant or object it touched by a pest. Embodiments may incorporate other methods of detecting movement of the surface that is being vibrated or moved.
Embodiments incorporate light measurement utilizing a light sensor 42. An embodiment may incorporate solar power but this solar power not be adequate for control of operation based on lighting conditions. The light sensor 42 provides the apparatus with the ability to compensate, alter, proportion or eliminate the characteristics of vibration and sway based on light conditions. For example, cloudy days, sunny days or even just a slight change in weather may be used as trigger points. In addition, the vibration level may be continuously adjusted and compensated for based on light level vibrating harder during times when pests are active.
Embodiments may use a variety of parameters in addition to light for adjustment of the vibration characteristics. Embodiments could include but not be limited to temperature, light, humidity, vibration, location, current, voltage, water, level, acceleration, pressure, barometric pressure, chemical presence, proximity, flow, sound, clock, time, date, synch pulse, switch input, or any other external or internal signal.
The LED 44 shown in
This embodiment is equipped with digital inputs and outputs 46 and Power/Control 48 and this is used to enable the device to respond to external inputs and/or control another device. This enables responses to events and feedback signals for various purposes. The outputs enable the device to respond in other ways other than vibration. Other embodiments may use any type of Input and output to provide this compensation and control.
The power/control 48 section in this embodiment is used to enable external control of the device to enable devices to operate in synch or out of synch. It is also used to enable external AC/DC or any other type of power to be supplied to this device. Embodiments may use various forms of control and power.
This embodiment utilizes a vibration generator control circuit 26 that uses Pulse Width Modulation (PWM) to control various aspects of the vibrations by using the PWM signal to regulate average DC voltage to the vibration motor in this embodiment; any level of vibration may be set with one control signal at any instant. Feedback in incorporated so vibrations no longer simply consist of a series of on off cycles in a certain range of amplitude and frequency. Fine PWM vibration control is also be used to control battery consumption.
In an embodiment, a four transistor H-bridge circuit is used to control the direction of rotation of the vibration motor. This gives this embodiment the ability to control the direction of the vibration force applied. This provides directional vibration control and the ability to impart sway in some surfaces.
This embodiment incorporates temperature measurement utilizing a temperature measurement sensor 50. Temperature may be used to compensate or determine the occurrence of a vibration signal. This provides the apparatus with the ability to compensate, alter, proportion or eliminate the characteristics of vibration and sway based on parameters. Extensive studies on beetle and box elder infestations indicated that cold temperatures often caused these populations to become lethargic. Vibrating when it was cold actually can cause pests to become latched on to plants.
Upon power up, the microcontroller loads the operating software and begins the operating sequence. An operational flow chart depicting an embodiment of a method 100 of repelling pests is shown in
Each profile stage has individual settings for characteristics of vibration, interrupt settings to advance to the next stage, and compensations for the current stage.
During many stages, the software operates in standby mode waiting to be woken up by next interrupt. With the extensive use of interrupts, many more extensive environmental/other signals are used to determine when to vibrate next. This provides for a much greater ability to fend off pests. For this embodiment, Japanese beetles have been studied extensively. Their habits prove that they often move much slower if at all when there is less sunlight. Using this method, the device may only vibrate when the sun is out and at a certain Lux level. Using a profile stage, the device may also only vibrate when its dark giving the user total control of the operating stages. This provides for total randomness for the timing and amplitude of the vibrations with respect to time, instead relying on the strength of the sun to determine when to vibrate.
In
During this stage, this embodiment can go through a cycle where a slowly increasing vibration signal is applied. The software utilizes the accelerometer to measure the response. In this embodiment, the invention is coupled directly to the surface and therefore the surface dampens the vibrations generated by the device thus changing the desired characteristics of vibration of the surface. Feedback is then used to compensate, alter, proportion or eliminate the vibration and sway characteristics. Utilizing this method, the surface the device is mounted to may be desired to a certain level rather than just vibrating the device at a certain level. Other embodiments may utilize a sensor that is not mounted directly to the device itself to sense vibrations. The connection to the sensor in that embodiment may be a wire or may be wireless.
Once the setup and self-calibration are complete, the software continues on at
At 114 a determination is made if a new stage or current stage is occurring. If it is a new stage, then the stage number in the profile is determined at steps 114-124. These steps include starting a new stage 116, incrementing stage pointers 118, determining if this is the last stage at 120, if the stage is the last stage, resetting to the first stage at 122, and clearing the stage status starts at 124.
Once the appropriate stage number is determined, the software sets the vibration level output as shown in
As shown in
Rather than use standby mode, the software may also stay operating as the profile has a series of possible types of control and compensations that it may utilize while vibrating. Control parameters may include target output signal, mounting correction factor, sway, acceleration, time, temperature correction factor, light correction factor, direction, and power correction factor. The path shown in
The compensation in steps of
Profile actions may not include vibrating at all for a particular step. For example, in many hours of observing the behavior of Japanese beetle infestations, it is not advantageous to vibrate at low light levels. For this, the profile stage would set an interrupt to wake out of standby when a desired LUX level is achieved. Standby mode is set as shown in
The establishment of standby mode as shown in the embodiment of
Action in any stage may simply be to flash the LED or turn on or off a control output. Embodiments would include control outputs triggered by the profile steps.
Through a series of experiments in control in addition to vibration, this embodiment is able to control sway. Observations show some pests became accustom to simple vibrations. Therefore utilizing this embodiment's centrifugal force, the invention was able to impart movement. With movement, the physiological response from pests may change. The sway is achieved with short varying profile steps, alternating the vibration direction using the H-bridge circuit resulting in considerable back and forth movement. Because of the unlimited number of profile stages, the vibration characteristics may be altered extensively and any type of movement may be generated. Other embodiments may use other means to generate movement.
A profile may have any number of steps and once the last step is reached, the profile resets to the first step. At the first step, operation restarts at
Currently many different devices exist which vibrate for various purposes. These devices include pest repellents, toys, cell phones, video game controllers, pagers and human gratification devices. For generating vibrations, these devices may generate vibrations at various amplitudes and in various frequency spectrums. These devices are tuned for specific responses by humans, insects, and animals. These devices only utilize methods which incorporate preplanned or random amplitude and frequency. This severely limits the effectiveness of such devices. They do not consider that vibration forces can be much more effective for eliciting a response in different species when considering X, Y and Z vibration components, direction of applied vibrations (forces), rate of change of vibrations, acceleration of vibrations, sway, and resonant frequency(s) (vibration characteristics).
Some devices vibrate sometimes two or more times or randomly as well. They typically lack the intelligent control found in a microcomputer based controlled system where control is not simply turning on and off twice or more. More importantly, these devices only base the occurrence of their next vibration step on waiting an elapsed time.
While some devices propose to have vibration characteristics tuned for certain pest behaviors, further limiting these devices is the lack of feedback system that allows the device to change or optimize the vibration characteristics. All known devices actually vibrate the device at a certain desired amplitude and or frequency with possibly a desired target in mind. These targets are typically obtained before the device is installed through scientific observation. A device may desire to elicit a preset certain amplitude or other characteristic of vibration to control pest behavior in a certain range but does not achieve the desired range when the vibration is generated. An example of the difficulty in vibrating a surface at known amplitude would be to consider a vibration device coupled to a concrete wall. It is desired to vibrate the wall at a certain amplitude or frequency. Once the device is attached to the wall the amplitude may not be adequate to achieve a vibration level and also will differ if coupled to a different type material or an even a different density concrete. Each material has certain stiffness and surroundings may absorb vibrations. In reality, to the best knowledge of this inventor, all pest control devices actually vibrate the device at a desired frequency or amplitude. They do not actually vibrate a surface they are seeking to vibrate at the known value because the surface to be vibrated absorbs vibrations thus changing the amplitude of vibration.
Pest control and other devices attempt to elicit a certain behavior using vibrations with certain assumptions or laboratory measurements of the behavior of a species in reaction to the vibration amplitude or frequency. These devices do not take into consideration that many environmental conditions will affect a species response to vibrations. For example, Animals, insects, humans and other species become lethargic when cold or at night/day and thus change their behavior and response to vibration or other stimulus. Current devices typically lack the ability to alter the desired vibrations to match the changes in a pest response to those vibrations due to environmental changes.
Embodiments as disclosed incorporate an accelerometer or other parameters to control or optimize the vibration or sway characteristics which may be the result of the vibration generator.
Embodiments as disclosed incorporate feedback of vibration and sway related parameters to enable corrective action to the desired results. Embodiments further consider additional parameters which may be used for corrective action.
Embodiments as disclosed further consider and control of different vibration characteristics. In embodiments, vibrations are not simply one or two or more because vibrations are not strictly time based or period based. Always vibrating two or more neglects the effect of surprise by periods of non-vibration. Devices which vibrate one or more or two or more times simply rely on time or counts to determine when to vibrate the next time rather than rely on other parameters to determine the next time to vibrate. Embodiments may incorporate feedback of the vibration and sway characteristics to enable corrective action to achieve desired or optimum results and additional parameters which may be used for corrective action and change the fundamental nature of the vibrations applied. Vibrations no longer need to be fixed at discrete predetermined levels, they evolve based on parameters. Stages of vibration in this invention are no longer necessarily time based.
Often vibration characteristics and sway desired differ in the laboratory environment than those achieved outside of the laboratory when a device is used. Real world uses can be improved drastically by measuring parameters related to the vibration and sway characteristics in real time and adjusting the characteristics accordingly. This enables a device to auto adjust its characteristics to a plurality of materials, environments, habitats and locations. Adjustments may be made to increase effectiveness of the device for changing behavior/repelling pests or prevent damage to structures or plants. In extensive testing conducted monitoring sway and vibration using the invention on trees, testing indicated that a device which was mounted in a certain orientation would cause less vibration that a device mounted with another orientation or location. For example, a device mounted on the base of a tree would cause very little movement but a device mounted on a branch tip would cause extreme movement. Intelligent use of feedback from measured or calculated parameters would enable the device to adapt to those different conditions or change its function altogether. For example, a device, may sense an external vibration or other condition which would indicate a bird or animal is present and may vibrate/sway back causing the bird to move.
Often many other additional parameters have an effect on the response of a species to a stimuli and the subsequent operation of the device. It would be desirable to monitor and consider one to many other parameters to make a vibration, sway or other action more effective to a species. A device which considers other parameters would enable a device to adapt to parameters which determine the effectiveness of vibrations and sway against different species.
An example of how to use parameter feedback might include compensating/changing vibration or sway characteristics when it's warm, cold, windy, rainy, night, day sunny, cloudy etc. Any of which, under extensive observance and widespread scientific evidence, affect the responsiveness of species to stimulus such as vibration and sway.
A device may further use a date parameter to determine what part of the calendar season to vibrate. This device would then not vibrate twice or more as in some devices. It would not vibrate at all depending on the date and/or season. Many pests do not emerge until certain dates; times or until average temperatures reach certain points in certain areas of the world.
While the invention has been described with reference to a preferred embodiment, those skilled in the art will appreciate that certain substitutions, alterations and omissions may be made without departing from the spirit thereof. Accordingly, the foregoing description is meant to be exemplary only and should not be deemed limitative on the scope of the invention set forth with the following claims.
