Laser detector

CN201407998Y

The utility model discloses a laser detector which comprises two pieces of glass, a detector, and a terminal device connected with the detector. A KIO powder layer is arranged between the two pieces of glass; and the detector is arranged close to one piece of glass in the position corresponding to the irradiation position of external strong laser beam. The utility model has the advantages that the KIO powder layer is arranged between the two pieces of glass, the detector is arranged in the position close to one of the piece of glass and connected with the terminal device, so that when the strong laser beam irradiates on other piece of glass, and then penetrates the KIO powder layer and one of the pieces of glass, the detector corresponding to the irradiation position of the strong laser beam is used for collecting optical spots of the strong laser beam and transmitting the collected spots to the terminal device, and the terminal device records the optical spots. Therefore, the shape and the appearance of the optical spots can be observed directly through the terminal device, and can be analyzed through the image analysis software in the terminal device to obtain optical intensity distribution.

In this invention, a kind of chemical powder is used to detect the laser beam, which is placed between two layers of glass. It needs to be replaced or retrieved with each exposure and has no alarms. What is clear is the use of a method to detect the presence or absence of a laser in a location based on changes in hearing in a composition that did not use the laser itself to detect.

Laser detector

JPH01248573A

PURPOSE: To prevent noise due to the interference of a laser light from generating in a laser light photodetector by disposing a scattering unit for scattering the light in front of a laser light photo detecting surface.

CONSTITUTION: A light emitting element 1 faces a photodetector 2, and they are so disposed that a laser from the element 1 is detected by the photodetector 2. A scattering unit (scattering sheet) 3 is mounted in front of the photodetector 2. In such a structure, since the laser from the element 1 collides with the sheet of the unit 3 before it arrives at the photodetector 2 when the loser is radiated to the photodetector 2, the laser is scattered. Then, the scattered light is radiated to the photodetector 2. When the scattered light is radiated to the photodetector 2, no interference of the light occurs on the photo detecting surface of the photodetector 2. The light intensity distribution on the photo detecting surface becomes constant by means of the multiplex reflection of an oxide film on the surface of the photo detecting surface. As a result, noise due to the cause of the interference is reduced.

In this invention, a map of which is not available due to its age, laser deviation measurement is used by two separate sensors to detect the laser itself, which is different from the method of detecting smoke, movement, temperature and vibration, which are claimed by this invention.

Process of testing an electronic smoking device

WO2016169797A1

In a process of testing an electronic smoking device, in particular an electronic cigarette, process of testing an electronic smoking device, an electronic smoking device (2) to be tested is mounted at an inlet port (12) of a testing apparatus (20; 10). Puffs are exerted at the electronic smoking device (2), using the testing apparatus, each puff being defined by a puff sequence comprising an inhalation period and an exhalation period. At least one optical property of aerosol (22) de riving from the electronic smoking device (2) is measured in an optical measurement device (20), which is part of the testing apparatus. The optical measurement device (20) comprises a light source (24), preferably a laser or an LED source, and at least one detector (28) arranged for measuring the scattering of light emitted from, the light source (24) and passing through the aerosol (22). Said detector (28) is arranged at a scattering angle with respect to a straight light path from the light source (24). The scattering angle is preferably in the range of from 60° to 120°, and, as an optical property, a signal at said detector (28) is determined.

In this invention, by referring to the technical drawings presented and the claims of the German inventor, it can be seen that to reveal the amount of aerosol in cigarette smoke, the amount of light scattering at the time of inhaling or opening the smoke has been used. Obviously, only the radiation and the amount of scattering in the path to reach the sensor is used without any reflection, which is very different from the main function of the claimed patent, which was to reduce the intensity of radiation in the path of the laser closed polygon. In fact, in this device, the intensity of deviation is the measurement criterion, but in the laser detector device, the amount of reduction in the presence of smoke.

Multi-signature fire detector

WO1996041318A1

A multi-signature fire detection method and apparatus, utilizing first (1) and second (2) detectors for detecting first and second signatures. The first (1) detector outputs a first signal (A) indicative of the first detected fire signature, and the second detector (2) outputs a second signal (B) indicative a second detected fire signature. A signal processor (3) is provided for combining the first (A) and second (B) signals using a number of correlations, wherein outputs of the first (1) and second (2) detector means are coupled to the signal processor (3), and the signal processor (3) compares and combines the first (A) and second (B) signals to a first predetermined reference value (303), and outputs a fire condition signal if a combination of the first (A) and second (B) signals exceeds the predetermined reference value (303).

In this invention, which is done by several methods such as measuring the intensity of the input laser to the photodiode and comparing it with the laser output from the detection generator, it can be easily found that no reflector has been used, which is the main subject of our invention. Wire transmission is also used on both sides. In this invention, the purpose was to remove the wiring and measure without the need for electrical energy in between.

A new infrared laser based alarm

WO2006130014A1

The subject invention relates to a new alarm which is based on using a quarternary tuneable Mid-IR laser to measure both particles and gas at the same time. The measurement is done within an area of which the gas of interest will absorb the Mid-IR radiation. By widely tuning the emission wavelength of the laser, several wavelengths can be measured in order to accurately find both gas composition and particle density with one laser based sensor. We tested a new device which use radiation between 2.27µm and 2.316µm. Metane gas reduces intensity of the radiation at certain wavelengths in this device, while particles/fog reduce intensity for all wavelengths. In this case, fog should not trigger an alarm, while methane leaks should. This can also be applied for CO and smoke in which one sensor will measure both parameters to sound an alarm instead of just one parameter.

The main basis of this invention is the use of appropriate wavelengths for the detection of methane or carbon dioxide, which is not claimed in our invention in terms of wavelength, and in some cases may even be needed to measure the abnormal presence of water vapor. In a sense, these two inventions can be used as complementary in certain cases.

Arrangement in a smoke camouflage system

WO1990013787A1

The present invention relates to an arrangement for a smoke camouflage system, preferably for the camouflaging and/or screening of point targets (8) in fortresses, airports or similar, especially against attacking precision guided weapons, and for the purpose of producing an effective system for emitting screening smoke comprising active screening materials, there is suggested that the arrangement comprises means for emitting screening smoke in the form of metallic powder, preferably brass powder, to which there is added a material for diluting and improving the cold-flowing properties thereof, for example aluminum silicate particles or a sand-blowing material, the devices for emitting the composition comprising one or more nozzles (6), preferably high pressure nozzles (1, 6) for emitting one or more spreading clouds.

In this invention, it is observed that in order to divert the guided systems that are guided by smoke interception, small metal particles have been used and scattered around the object and there is no measurement in it.

Aspirated particle detection with various flow modifications

WO2015054749A1

A method of particle detection in an aspirated particle detection system, the system having a sampling pipe network and a particle detector. The sampling pipe network includes at least one sampling pipe in fluid communication with the particle detector, a plurality of sampling inlets through which sample air can enter the at least one sampling pipe, and an opening in the at least one sampling pipe upstream of the plurality of sampling inlets, wherein the opening has lower flow impedance than any one of the sampling inlets.

The method includes drawing sample air to the particle detector through the air sampling network; analyzing the sample air with the particle detector; entering an amplification phase, in the event that a concentration of particles in the sample air greater than a predetermined threshold is detected, to create a plurality of sample air packets in the sampling pipe, wherein each sample air packet corresponds to a sampling inlet and includes an amplified concentration of air drawn from the corresponding sampling inlet; transporting the sample air including the plurality of sample air packets through the sampling pipe to the particle detector; and determining through which sampling inlet any particles entered the particle detection system.

In the above invention, the detection of respiratory particles in the sampling tube is discussed, which, despite the lack of similarity in laser detection in detectors, has been shown in the above search results.

Laser smoke / motion / vibration / temperature detector without the need for electrical energy is a device in the field of protection and security facilities of places and buildings which has the problem of the need for wiring and power supply to detectors, the need for multiple detectors to measure different parameters by the use of temperature physical effect, shadow and light refraction on the angle and intensity of laser reflexes which has the ability to show the passage of objects through the detectors and the abnormal increase in temperature and vibration of the detector installation surface and the passage of smoke in the plow path. The problem of a Proper range in remote control and errors display on the mobile phone has been eliminated by adding a Wi-Fi wireless connection. In the design of the main module, the possibility of increasing and transferring information to peripheral modules, which is one of the biggest problems upgrading similar systems is removed by adding the standard power/data connector and several problems of the remotes have been solved in the infrared remote by the ability to receive and send information equipped with wireless charging and the ability to display errors and events.

The need for electrical energy to measure and transfer data to the central device is one of the detectors’ problems that existed until the patent registration time. We also needed several detectors to measure different stimuli. In this invention, the presence of smoke, moving object, overheating, and impact will be revealed by the use of several law of physics and their effect on the intensity and laser beam’s angle in a closed polygon from the transmitting device to the receiving device, which are placed at the shortest distance from each other

Solution of problem

As it mentioned in the problem statement section, supplying the electrical energy for the installed detectors in large work environments is difficult and it is associated with a decrease in reliability. Also, each detector measures one or two parameters.

In this type of detector from the radiation source (1) to its return to itself, the stimuli are measured only by irradiation and laser irradiation. Using this method is possible due to the low light divergence of the laser coherence. The central device (2) provides the required power of the generator and the sensor (1) and reviews its information. Laser radiation in reflectors which is used as detectors (3) will create a closed polygon in a path (5) and its return path (4). Also receiving and sending information to the infrared remote control (85) will be conducted by this method. Due to the possibility of transmitting radiation through used mirrors, the ability to access input port (7) by the fiber optic (8) to the first mirror detector will be provided. But the detectors (3) are made of two adjustable mirrors and each of the mirrors (9) can move in the horizontal and vertical direction by two adjustable screws (16).

The initial adjustment and vertical placement on the ground will be conducted by a level tube (2) in order to minimize the mirror displacement in the vertical direction. The base is connected to the wall by screws (11) and roll plate (12). Then the adjustment of laser generator (1) will be conducted on the first reflector (3) by the joystick key (64). In the entrance door area (6) or any other significant entrance by using a considerable number of detectors (3) the interrupted path by the passage of objects will be considered. In this invention, the “detector”, “reflector”, and “revelator” word will be used instead interchangeably, because the function of detectors will be done by reflection and they have the same meanings. After installing the detectors on the wall, the amount of ineffective temperature tolerance advance will be adjusted by the screw (27) and then it will be adjusted on the next mirror by screw (16) which is connected to the mirror by a ball/bowl joint (15).

As we know, the angle of radiation is equal to the angle of reflection and the direction of path or return path will be adjusted based on this law. It was mentioned before; in addition to the cottage of laser beam because of object passage from the detectors (3), there are three other usages. The direction of travel or return path is done. There are other boards. If the temperature rises, the ether liquid (19) which is in the storage will increase in volume and limit the cylinder (20), piston (21) and the rings (22) and they will cause the connector (23) to move toward lever (24). The lever (24) that rotates around the axis (25) is always pressed by the spring (26) to the interface (23). This function is very similar to the car thermostat system.

To prevent unwanted slip of the lever (28), a return spring (29) is used, which always keeps the lever (28) at the highest possible distance between the adjusting screw (27) and the base (30). By changing the temperature in this detector (3), the laser beam will be deflected to the left or right. To control the vibration, we have used the mirror support base, which is a kind of ball and bowl joint. In fact, in order to adjust the mirror (9) in the horizontal direction and perpendicular to the ground, we needed a joint with freedom in both directions. The use of a plus-shaped connection - four horns - and a ball and bowl connection were the available options, and the second option was chosen because of its higher accuracy. Considering the fact that most of the vibrations of the surface have a very small movement perpendicular to the wall surface, the movement of the pendulum (31) will transfer its power through the arm (32) by rotating around the axis (33) to the base (35).

According to the law of inertia, the slightest vibration causes a movement in the base (35) and as a result, the ball (36) will eventually turn toward the spring (34), which will cause the vertical deflection of laser in upward and downward direction. This property is used to measure vibration.

So far, 4 excitation modes have been expressed. The first state is laser interruption, which means the passage of objects through the detectors and the possibility of unauthorized entry. The second state is dimming due to the smoke in the polygon path. In the third state a deflection will be detected in the horizontal direction and in the device it means an increase in temperature. The fourth state is the upward and downward deviation, which indicates the vibration. Obviously, physical beauty is one of the main criteria to purchase. Maintenance have a positive effect on different parts' performance. Therefore, tow coverage parts (37) and (39) were used in this detector (3).

While installing the lower part (37), which is about half the thickness of the detector, it is fixed on it. Then, after fixing the mirrors on top (39) it is pressed on the lower part (37) as long as it does not disturb its function. The fixture is on bumps (38) and these parts are often made of plastic with the injection method. A special equipment (1) is needed for radiation and measurement of infrared beam that can be adjusted in the required directions. According to the previous description of this part (1), it includes support base on the device surface or wall (40) base connection arm (41) ball-shaped tip (42) wire passage (43) bottom frame (44) placement of mechatronic controllers (48) cap-like cover frame (45) emitters of radiators (46) and reflectors (47) located on the lid (45). High accuracy in adjustment of this part requires the use of high-precision control methods that have been fixed on the body (44) by the use of mechatronic controllers (48) and it is made possible by rotating in the horizon and perpendicular direction to the ball (42). This rotation is done by the ball (49) which is tangential to the central ball (42). However, the ball-bearings (50) have restricted this ball to a one direction rotation.

It should be considered that connecting the balls to the balls has some advantages over connecting the cylinder to the ball, which allows movement in the direction of rotation for other controllers. To control this rotating ball (49), and its connecting axis (51) gearbox (53) c used after reducing the number of revolutions and increasing the power. The required driving force is available through the electric motor (54).

After the adjustment challenge which is performed by the joystick (64), it is important to measure the direction and amount of reduction or deviation. Diode power (59) was used to produce laser coherence light due to the possibility of visible or invisible spectrums. Because of the lower power of infrared diode emitters and the urgency of special remote operation, the number of transmitters (60) has been increased to 4, which are protected by a frame (61). We also have 5 laser receiving areas in the receiving area. The central photocell (55) and the lateral photocells (56) will measure and detect the intensity and direction of the deviation. In receiving the infrared, direction is not important and it can be conducted by the diodes (57). According to the presence of radiations in the similar wave the possibility of coding and decoding has been considered for both radiation spectra by the CPU (81). The protection of this part is also done by the protective frame (58).

Despite the possibility of using this method with existing devices - only by placing the interface – in order to achieve a better result, the design of the central device of the burglar alarm has been done based on the existing needs. This part, like other devices, includes the main parts of the lower body (62) Where the wires enter from above (63) - which is one of the installation problems - joystick key for direction adjustment (64), cover lid (65), display (66), main keyboard (67) keyboard dust protector (68), The dust protector of the monitor (69), are placed outside of the device. In order to protect the keyboard (67) and the monitor (66) as much as possible, a certain angle to the ground has been defined, which needs the minimum cleaning. Inside the device, a power supply of 5 and 12 volts (70) is used, which has multiple isolated outputs. According to any other security system, a rechargeable backup battery (71) is supported during a power outage. It is responsible for the connected circuits and this battery is called the backup battery. The wire entrance place in back of the device (72) can be seen as vacant parts, so there is no need to cut the frame.

The device is mounted to the wall by screws (73). One of the biggest problems in upgrading similar devices is the need to replace the main board or to place side boards with unprincipled methods in the frame of the device. In this device, placing the main module (74), which is connected to the device frame by screws (99) and base (100), can increase the required performance by the side modules in the simplest possible way. For example, in this device, the siren module (77), Wi-Fi connection module (76), and the detectors connection module (75) are observed, which is simply possible by placing them on the connector (79) the empty spaces (78) and closed screw. It is considered that there are two pins for power supply and two pins for sending and receiving the data on 4-pin connectors. Also to control the off or on mode of the device remotely, using Wi-Fi and connecting to a mobile phone has solved the problem of having a remote, which is not desirable for most users.

Due to the appropriate range of this method and the availability of device information without the need to open and close, the above mentioned data transfer method has been selected. Main board electrical module (74) is on the north part of a powerful processor (81) that will provide us with different connections and suitable inputs and outputs in different ports. We will have different power supplies by connector (82) and different outputs and inputs in connector (83) and (84) which can be done by changing the microcontroller program. Also in each connector the required power supply is considered in its possible increase. Keypad (67) and joystick (64) have used only one port.

Due to the possible temporary need of different people to turn this device on and off (2), the definition of their mobile phone with WIFI system would be irrational, and as a reliable backup, there should be a suitable remote control on it (85) which uses the IR wireless data transmission method. By standing in front of the receiver port (7) which is connected to the internal network by fiber optics (8) it can perform the relevant control and receive data defects or a report. The battery of this remote (88) had the ability to charge wirelessly by the coil (89) after rectification with the help of diode bridge (96), which while charging the LED indicator (97) confirmed the correct position on the stand. Remote heads (87) are sliding to create good physical resistance.

By pressing each key forward or backward, the key heads (87) are like drivers and they can create an appropriate physical resistance. By pressing a key forward or backward (87) around the axis (90) it will rotate and overcoming the spring force (92) and press the return force of the micro switch (93), and send a command to the micro controller (98). In the current method, by pressing a command momentarily and holding a separate command and pressing a combination of keys, we will have a different command that eliminates the need to put many keys on the remote.

Usually a function summary of simple or combined keys will be written on back of the remote. In this remote, the infrared port (90) is used to send and receive information and commands, and the display (86), which is selected as OLED, will display the information. The relatively large size of the remote reduces the tendency to its daily use, which replaces the use of mobile phones and the depreciation of the remote. Microchips (94) which are connected to the body by printed circuit (94) and screws (95), can easily be replaced and reduce the physical pressure on the electronic board, which is the biggest problem after impact and water corrosion. Placing the printed icons at a lower level from the contact surface of the hand has minimized the possibility of erasure over time.

Advantage effects of invention

In designing these detectors, the physical properties of laser radiation, reflection and a few simple physics law were used without power cords, which was the main problem of installing previous detectors has been solved. In these reflectors, building inconsistent subsidence will occur which is optimal. Another advantage of this design is the possibility of warning the abnormal situation of several parameters by installing only one detector without the need for wiring. Using the infrared remote as a fault detector and a reporter is another advantage. Also, using Wi-Fi mobile phone as the highest distance available without the need for a SIM card eliminates the need to carry a remote control in normal use.
