This way, even if other drivers close their windows and turn on the music in the car to a loud voice, they will not be unable to hear the siren. Pen "Fun" Pavilion www.biquge.info

Because the high-frequency sound of the siren will more or less enter the ears of other drivers, and the low-frequency tremor of the corresponding frequency is even more unstoppable by the car body.

The high and low frequency sounds complement each other and will directly stimulate the person who hears the sound, as long as the person is awake, then it will not feel the arrival of the police car.

In this case, if they still don't give way and don't cooperate with traffic, the police can prosecute them, and the lawyer's lawyer can't exonerate them.

The alarm also has the benefit of reducing the frequency of sirens, which New Zealanders hate when police cars whistle and whistle past their homes.

With a low-frequency alarm, the high-frequency sound of the siren is just for show.

Aocheng was in charge of the modification of the police car, and on Tuesday Wang Bo drove over with his men, and Sheriff Smith smiled when he saw it, saying: "Every time I see your police car, I think it's very interesting." ”

Sunset's police cars include sports cars, jeeps, SUVs, and even if New Zealanders value individuality, few police cars in a police department are as complex.

Holding Wang Bo's police car and joking, Sheriff Smith asked the secretary to hand him a cup of coffee and asked him the question he was most concerned about: "How are my two police dogs trained?" ”

Wang Bo was prepared and turned on his mobile phone to show him the video.

The heart of the beast field also has an effect on the two puppies, which can slowly open their intelligence to a certain extent, so with the training of Brother Bing, both puppies have recently gained.

In the video, Brother Bing demonstrates various passwords, all of which are relatively simple, getting up, sitting down, forward, backward, refusing to eat, running, jumping, etc.

Sheriff Smith's eyes lit up when he saw the video, and he watched it twice before he stopped and asked, "How many commands have these two dogs learned now?" ”

A dog that can learn twenty commands is a qualified police dog.

However, this question stumped Lao Wang, he was not a dog trainer, and he did not care about this problem.

So he could only open his mouth and come: "Oh, they are very smart, they have learned eighty or ninety commands. ”

"Eighty or ninety?" Sheriff Smith was stunned.

Of course, this was a misunderstanding in communication, Wang Bo habitually used Chinese English, and said eighty or ninety to eighty to ninety, so he explained.

Even after learning eight or nine commands, Sheriff Smith was satisfied, and the puppy was still a little over two months old, and it was a miracle that he had learned so many instructions at this time.

Police dogs have an important place in the New Zealand police system, and there is a saying in police circles that you have a dog when you have nothing to do.

Therefore, Wang Bo now has an extraordinary status in the Aocheng Police Department.

Aiwu and Wu, his status is high, and the status of the police car he brought is also high, and the repair shop that cooperates with the police department first modifies and upgrades their police car.

The mechanic in charge of changing the car said: "Sheriff, I would like to introduce to you first of all that although the low-frequency alarm is effective, the low-frequency sound waves are very annoying, and can even cause physiological disorders in the human body. ”

"Therefore, this is limited in use, it can only be activated manually by the driver at the same time as the high-frequency alarm sounds, and the conditions for activating it are as follows:"

"First, chasing the car, and the car in front just doesn't stop."

"Second, through a busy traffic intersection and there are a lot of vehicles moving."

"Thirdly, the police car is blocked, and the vehicle in front of it is not proactive enough to give way, so that it can be driven away."

"And at night, or when there are not so many traffic participants on the road, it is better for the police car not to use low-frequency alarms, after all, you swore when you joined the company to enforce the law humanely."

Wang Bo thought about it, did he ever make such an oath? If you don't have an impression, you haven't sent it.

The difficulty of this system is that it is necessary to unify the high-frequency siren sound and the low-frequency alarm, and the installation is very fast, which takes an afternoon, Wang Bo and others went shopping in Aocheng.

The major hospitals in Aocheng began to carry out the biennial women's **** X-ray examination activity, Wang Bo scratched his head after seeing it, and said, "We should also start this activity, right?" ”

Aturu smiled and nodded: "Yes, boss, I hope I can help Brother Yi then, after all, I also belong to the hospital." ”

In New Zealand, women have a unique health benefit of receiving a free x-ray every two years.

It is a health screening programme designed to help women detect breast cancer at an early stage, rolled out across New Zealand with the simple aim of reducing the mortality rate of breast cancer among women.

Breast cancer is very prevalent among women around the world, and women are more likely to develop breast cancer as they age.

It hurts to know that there is no better way to warn of this disease than to check for it.

According to statistics, three-quarters of women with breast cancer are over the age of 50, but most women with breast cancer have no family history.

In other words, according to statistics, it is not possible to judge whether a woman is prone to breast cancer based on family medical history, and it is best to pass the examination.

The census is biennial, and the last time it started was that Sunset Town did not have a community hospital, so it could only be conducted at Aocheng Hospital.

Now that Sunset Town also has a hospital, it is easier for the women in the town to check up.

This job naturally involves dealing with women, and it is still a bit tempting for men.

The police car was equipped with a low-frequency alarm, and the group went back.

Wang Bo wanted to go to the hospital to discuss with the doctor about the immediate census operation, when the Serbian carpenter Dayan told him that the first observation deck had been erected.

The observation deck is to be used in the beast field, and Dayan is also working there, Wang Bo has only paid attention to the flower field during this time, and the animal farm has not paid much attention.

When I drove to the animal farm, I saw a wooden tower at least five or six meters high from a long distance.

The wooden tower is built in a modest manner, using monitored Kolei tree heads and pine wood.

Dayan has set up two levels of observation decks, the middle and the top floor.

And he handled the problem of movement very skillfully, with large tires installed under the observation deck, which can be used to strengthen the stability of the observation deck, and if necessary, they can also be used to move.

Dayan said: "When you move, you just need to use horses to pull it, and I see that there are a lot of horses in the racecourse now, and you can use them. ”
