Posted by Unknown Friday, January 10, 2014 0 comments

The battery of this kind of good cell phone jammer is the durable type.
Hybrid satellite and terrestrial solutions to the countries covered by geostationary satellites in low-power repeater network and the mobile base station co-location, to provide urban and indoor coverage. The manufacturers argue that, if you do not use the S-band in the country coverage of the DVB-H in UHF is not economical because it requires a large number of transmitter and receiver. The market is still before the analog shutdown mode, the lack of available digital spectrum to support deployment of this technology, at the same time, the S-band frequency bands are available in any place. Manufacturers are expected to DVB-SH will commence in Europe for land the citys commercial, the end of 2007 to 2009, there will be a dedicated satellite to provide country-wide coverage. The product description of cell phone jammer should be as exact and accurate as possible.Several shielding positions of cell phone jammer locate at sides of hallway
A variety of software in the smart phone Forum, endless domestic mobile phone software applications has just started, users do not have a strong ability to identify, the results appeared in fish, wanton rampage rogue, front-end on the occurrence of an influential and destructive strong OPDA trays "incident, in the new software, especially the OPDA smart phone Forum, users claim that a famous foreign software crack, the results of the user under the computer all automatic grid, resulting in a lot of bad impact. On the computer, the rogue software on the phone more than is deducted user fees, get money for the purpose, so the worse nature, some commercial software is self-defeating. The customer should use and maintain cell phone jammer in the suitable manner.
User pull: In Japan, mobile payment wallet alternative is obvious. Buy virtual goods online supermarket shopping and spending, take the subway, take the bus, hospitals no longer need to queue up, the airport do not have to queue up for boarding passes, dinner singing and watching movies. Almost all of the daily consumption can be by a brush easy to get. In China, after years of gestation period, the user has the convenience of mobile payment is more recognition. The market potential is huge: CUP data show that the first half of 2009, Chinas mobile payment users exceeded 19.2 million, a transaction of 62,680,000 results, the amount to be paid a total of 17 billion yuan of transactions and transaction amount increased by 42% and 64% respectively than last year.
But will have on the wireless network in seconds, this speed is too slow to run a network game. Mobile operators strive to improve the mobile phones available bandwidth, network latency has not been satisfactorily resolved.

Requestors are as many as cell phone jammer
Obviously, if we choose the conditions to determine if else, to judge the success of the conditions in the final else, we will unfortunately have to get to the data compared with all possible scenarios, a switch is the efficiency of many, will jumped into the branch we need this code is written in the run thread, that is, before closing the game will be an unlimited number of execution, we add a counter in the run thread, and then entered the game in figures do not move, in this case, the code will not enter the case branch, which is the optimal point in time when the first run to this location is 13.343 seconds, 101 runs to the time of the position point is 34.062 seconds. The aluminum alloy frame of cell phone jammer is adopted.
Similarly, we enter the game, to maintain the character does not move, that is, without any action, but this is probably the worst, the code will be detected from the first branch to the last branch, all the keys to match the detection side, If the characters move around will match from the middle position out of our characters do not move the case to record the implementation of the 1st to the point in time of 4.531 seconds, 101 times the execution time of 25.453 seconds, during which total consumption of 20.922 seconds for a total of 100 times, after the optimization of this process, the running time is reduced by 0.203 seconds. see that our optimization method is indeed to improve the effect of the code speed. Second, mobile phone game scale lack of technology, mobile games and there is no single industry standard, game developers to launch the game can only be run on a specific platform, which greatly diminished its market potential. cell phone jammer can act on CDMA, GSM, PHS, PCS, DCS and 3G.
Game mobile game service providers, but it is fragmented and have little effect, unlike the computer network games as can organize large-scale computer and video games, to cultivate a loyal group of professional players. In addition, the phone memory is also a constraint to the limited phone memory can meet the needs of todays most common games and other entertainment applications, but the face of the next generation of games have become the biggest obstacle. example, the phone can only save four games.

The material test of cell phone booster cannot be cancelled
Further established the worlds largest cell phone users status. Industrial scale, concentration increased as of April 2007, 41 new cell phone companies, including 11 foreign-invested enterprises, Chinese enterprises to 30, with production capacity of about 140 million while the new cell phone manufacturers in the low-end products based mainly on the Chinese market, the annual demand of about 60 million to 100 million units, made in China to exceed demand and production companies to expand the number of cell phone production growth will further exacerbate the market competition increasingly fierce competitive environment has led to an overall decline in industry profits, loss of business and the amount is increasing. cell phone booster can work continuously for a long time. On the other hand, the Chinese cell phone industry to further expand the industrial scale, while also further enhance the industrial concentration which Nokia, Motorola, Samsung, Sony Ericsson, Bird, Lenovo, and Amoi top ten companies account for almost the total production of all 80% of the industry, including Nokia, Motorola, Sony Ericsson and Samsung, the market share of 81.96 percent, the domestic cell phone market share of SMEs is very limited. 72. handset industry value chain structure of the cell phone industry value chain structure divided into three two components: the upper reaches of cell phone R & D, design and component suppliers, midstream and downstream cell phone handset manufacturers brand marketers, operators in the mobile industry on a technical level, Chinas cell phone industry is still in catch-up phase, the total production level in the cell phone Chinese cell phone industry in rapid growth stage. The company only takes responsibility of changing a new cell phone booster or repairing cell phone booster .
Chinese cell phone industry cluster is still in the global value chain under the low value-added chain. Handsets needed for the production of most of the active and passive, body parts (only about 30% of production costs) can be made, but not yet fully grasp the industry core technology and key components of the production technology, and small-scale enterprises, SMEs accounted for 92.61% of the proportion of overall competitiveness. Chinese cell phone industry structure shows structural characteristics of olive shape: the upper reaches of the lack of core technology and key components industry production technology; River is gradually assembled a strong, general parts production capacity; and downstream of brand management, logistics are still weak. Upstream: cell phone design platform (chip module). Overall, Chinas cell phone industry cluster is still in the low-value-added chain of production processes and generally supporting the production of parts gathering stage of development.

Daylight harvesting is becoming increasingly important in the design and implementation of commercial lighting systems. Being able to integrate the natural light from windows with flexible, controllable sources of lighting helps improve the work environment and cut energy bills.

Being able to have closer control of the lighting systems in a commercial environment is a key element to this strategy and energy harvesting can play an important role. Being able to have flexible placement of control pads for a commercial lighting system is an important requirement as office space is regularly reconfigured as existing clients grow and change their requirements and new clients have new requirements.

1994 Volvo 850 Turbo Change the ECU with A Non Turbo ECU Parts

Posted by Unknown Wednesday, August 7, 2013 0 comments

When the ecu of my 1994 Volvo 850 Turbo was showing some bad readings about the knock sensors, I picked and pulled the old ecu and got a new ecu from a 1993 volvo 850 non turbo. Is it possible for an ECU from a turbo car to replace ecu from a non turbo car? Thanks.

Answer: No. The turbo creates a significant change, since the engine compression is changed significantly.
VVT
A/F Ratio
Wastegate control
Banked injection
Would be different or missing from the ECU. The knock sensor sends signals when the A/F mixture pre-detonates before it can be ignited by the spark plug, and the computer corrects it with VVT. You need to buy the correct ECU.

Guide to the Power Circuit and Control Circuit of the Wound Rotor AC Induction Motor

Posted by Unknown Friday, August 2, 2013 0 comments

In certain exceedingly enormous type of industrial applications where a tremendous amount of power is required to drive a specific type of load too large for the ordinary type squirrel cage induction motors to carry, the most appropriately preferred type of motor for use with such extensively large demand of power application is another type of large capacity motor which has the capability to run with high starting torque immediately attainable all throughout starting from when the motor is just beginning to run from rest even while it is at loaded condition up to when the motor reaches its peak rated speed while also carrying the same amount of heavy load, which would also necessitate for this type of motor to possess the ability to run continuously at different variation of steps of speed levels while driving a very heavy load. This type of motor is known as the wound rotor induction motor.

This so-called wound rotor motor as the name implies is a type of AC induction motor which does not only have stator windings but is also equipped with rotor windings. The terminal ends of its rotor windings are externally connected to slip rings and brushes as part of the motor assembly where these rotor winding terminates to terminal ends which are wired externally and connected further to an isolated resistor bank which is a separate necessary component to accompany the intended function of the motor to serve its purpose as a one whole complete functioning unit. The separate resistor bank unit connected to the motors wound rotor can be externally switched on and off at different intervals of resistor branches in the resistor bank, thus providing multiple stages of speed levels and torque capacity with an acceleration rate faster than would an ordinary induction motor could accomplish for similar types of bulky load applications to be driven.

Another purpose of the resistor bank connected to the rotor winding is to facilitate for the reduction of the very high inrush starting current, considering that the type of application that the motor will be subjected to requires for the motor to start running at a very heavy load condition.

The resistor bank also serves to absorb the heat developed in the rotor winding which is necessary for the intended application of the motor which is to have the ability to effectively dissipate the heat generated in such extreme load conditions, because rapid heat build-up is an inherent characteristic of very large capacity motors operating at very high load condition from zero speed up to its rated maximum speed or even when running the motor in any continuous variation of speed level falling anywhere within the various stages of speed range of the motor.
Fig-1 below shows an electrical schematic diagram of a three phase power circuit of a wound rotor motor. As shown in the drawing, you will notice that the motor consists of a stator winding which is the stationary part of the motor while another component of the motor is the rotor winding which constitutes the rotating part of the motor.

The stator winding is directly connected to the three phase power supply which provides the source voltage to the motor. The main supply voltage is supplied to the primary side of the disconnect fuse on the three phase terminals L1, L2 and L3 where the fuse serves as an instantaneous interrupting means with rapid action that immediately detects line side power trouble and motor circuit problem such as over voltage, over current, short circuit or overloads. The Main Magnetic Contactor (MMC) is a magnetic motor starter which serves as the motor operation switch which is electrically activated and deactivated remotely with an external push button switch in the control circuit. The overload relay is another type of overload protection device which is directly concentrated in instantaneously detecting motor overload currents that once detected would instantly trip-off to open the control circuit in order to deactivate the main magnetic contactor (MMC) to isolate power flow from the main supply line voltage going to the motor in order to prevent the destruction of the motor.

Fig-1: Electrical Schematic Diagram of the Power Circuit of a Wound Rotor Motor

The secondary part of the wound rotor motor contains the rotor winding. Fig-1 above shows the rotor winding connected to a resistor bank which consists of three resistors per phase making up a total of nine resistors in the entire resistor bank network. There are correspondingly three branches of resistors in the resistor bank which consists of the first branch comprising R1-R2-R3 resistors, the second branch being R4-R5-R6, and finally the last branch contains R7-R8-R9 respectively. Each stages of resistor branches are provided with their own individual magnetic contactor switches with MC1 for the first resistor branch, then MC2 for the second resistor branch and finally MC3 for the third resistor branch. Each of these resistor branches are shorted individually by MC1, MC2 and MC3 according to an order of operational sequence relative to the efficient running of the wound rotor motor.

The single phase step down transformer is made available in Fig-2 above is an electrical schematic diagram of a common control circuit which illustrates how the wound rotor motor is operated to run from standstill until it reaches its rated speed. The power supply source voltage of the control circuit is taken directly from the step down transformer provided in the power circuit in Fig-1 above which shows the reference terminals RC and SC coming from the secondary part of the step down transformer from the power circuit. The proper sequence of operation of the wound rotor motor is directly dependent on the construction of the control circuit based on the intended sequence of operation for this particular wound rotor motor.

The start operation sequence in the control circuit in Fig-2 above begins with the closing of the start push button switch which permits power flow to the main magnetic contactor (MMC) provided that both the stop switch and the overload relay contacts are maintained closed at all times during the operation of the control circuit. The auxiliary open contact of the MMC which is connected in parallel to the start switch serves as the holding contact which maintains the MMC coil energized even after the human operator releases the start switch, this in turn provides continuous power flow to the control circuit which further proceeds in commencing the sequence of steps in the operation of the entire circuit of the wound rotor motor.

During the first stage of the operation of the wound rotor motor when power is connected to the primary stator of the motor, the secondary part or the rotor is firstly connected with maximum resistance with all resistors in the resistor bank network fully active which initially runs the motor at its lowest speed. The flow of electricity in the control circuit would then proceed through the closed contact of Timer 4 going down to the Timer 1 coil which upon reaching its specified time delay period would then activate contactor MC1 to short the first stage resistor branch R1-R2-R3 leaving only the second and third stage of resistor branches to remain active in the resistor network to act on the rotor winding which will eventually increase the speed of the motor to a partial 1/3 of its rated speed.

The activation of contactor MC1 achieves the next step of the operational sequence that closes one of the auxiliary contact of MC1 to energize the Timer 2 coil which upon reaching its specified time delay period would then energize contactor MC2 to short out the second stage resistor branch R4-R5-R6 leaving only the third resistor branch to remain active in the rotor winding which further increases the motor speed to 2/3 of its overall rated speed.

Then comes the last and final stage where the previously activated contactor MC2 energizes the Timer 3 which when its specified time delay period expires would then activate contactor MC3 to totally short out the rotor winding to the fullest without any resistor branches remaining active in the network that can connect to the rotor winding, this final stage brings the motor to run to its fullest rated speed.

The activation of contactor MC3 would then provide a holding contact with one of its auxiliary contact connected in parallel across the Timer 3 contact while maintaining the MC3 coil energized during the final stage of this operational sequence.

This last stage would also activate and maintain the Timer 4 coil which upon reaching its specified time delay period would then open the Timer 4 normally-closed contact to remove power to the coils of Timer 1, MC1, Timer 2, MC2 and Timer 3 in order to release the first stage contactor MC1 and second stage contactor MC2 from shorting out the first and second stages of resistor branches but while also maintaining only the last contactor MC3 to remain activated to maintain the rotor winding shorted out completely hence maintaining the motor to run at its rated full speed.

To interrupt the operation of the circuit, the only thing necessary to manually stop the motor is by pressing the stop switch which would totally remove power to the circuit at any time during the circuit is active no matter under which stage of speed intervals the motor is actively running in. Another interrupting means in the control circuit is the overload relay which automatically shuts down the circuit to immediately stop the motor in case over current is instantly detected at anytime during the motor is running.

The food salt salinity tester meter circuit

Posted by Unknown Sunday, April 7, 2013 0 comments

A Salt
intake in large quantities is not good for the body and also causes of
diseases such as kidney disease, high blood pressure, heart disease and
paralysis. We should not eat too much. But the recognition of
salinity, but may differ. Therefore should be a good barometer. I
highly recommend The food salt & salinity tester meter circuit,
because it is simple circuit and cheap too.
The circuit ideals.

We use the comparator circuit by an op-amp IC. Which is the difference
between the volume resistance or conductivity of the solution foods has
salt is constituent. In with sensing probe immersed or dunk in the
water or food. Then Showing amount of salt much, Appropriate salinity,
and a little salinity with 3 different LED colors.
the-food-salt-salinity-tester-meter-circuit

the-food-salt-salinity-tester-meter-circuit

How the circuit works.

The circuit ready running When dipping or dip the probe into the
solution or food. Then press switch-S1, by has IC1/1(LM324) amplify a
differential signal, the voltage output at pin 1 as quantities
resistance or conductivity of the solution foods has salt component is
measured through the probe.
Which if a water or foods with little
salt as an ingredient. The resistance is quite high. Less current to
flow through it. The voltage comparator circuit so has the output at
pin 1 a few, As a result output at pin 14, pin 8 and pin 7 of
IC1/4,IC1/3 and IC1/2(LM324) have all high state, makes the LED5, LED4
and LED3 not glow.
Water or food, that have a salt is very
complement. Resistance is relatively low. Current to flow through much,
makes the output signal at pin 1 much into the voltage comparator
circuit , as a result the output at pin 14, pin 8 or pin 7 of IC1/4,
IC1/3 and IC1/2 has state is high only one or all, makes LED5,LED4 or
LED3 in order to light up.
Additional will use LED5 yellow. If
brightness is represented by the amount of salt. With little food or
water. If the green light is LED4 is represented by the amount of salt
in food or water has Fitted. And the LED3 will light red when the user
is represented by the amount of salt in food or water is too much.
