BroadWiMAXのオプション解約

今回ネットでBroadWiMAXのオプションの解約をしましたが引っ掛かりそうなポイントがあったので書いてみます。

オプション解約はサポートサイトでも行えます。そのサポートサイト自体は「契約開始の翌日2:00より利用可能」とありますが、私の場合契約書にある開始日から7日目にログイン出来る様になりました。ネット上では1か月かかったという情報もあり、「毎月25日が〆日となっており、1～25日までに申請いただいたものは当月末での解約となります。26日以降の申請につきましては、翌月月末での解約となります。 」とあるので、余裕を持てるように月頭の1日に契約した方がいいです。

上の写真は契約書とサポートサイトの解約前のページです。それぞれ有料オプションが3つ書いてありますが、契約書には「つながる機器保証」は「My Broadサポート」に含まれると書いてあるので、スクショのように「安心サポートプラス」と「My Broadサポート」の2つだけチェックを入れて解約を申し込めば翌日にはこうなります。

もしかしたら反映に数日かかる場合もあるかもしれませんが、申し込みが上手くいっていればメールも来ます。

「※ご契約商材や契約されてないオプション、誤った内容のオプションを申請された場合、解約の処理がされません。またその場合でも弊社からの連絡はございません」 ネットでの解約の肝はこれですね。おそらく「つながる機器保証」を選択した場合すべての解約処理がされず、それがユーザー側からは分らないという事だと思われます。ちょっと引っかけ問題みたいでここはあまり印象が良くないなと思いました。

How Do F1 Cars Work?: Braking, Cooling, Sensors

I never know how to start these posts. Let's dive in.

Braking and Cooling

Brakes are an incredibly important part of any car, but most especially in F1. With the speed and power the cars have a sensitive, sturdy, and strong braking system must exist. In the case of modern cars, F1 uses an extremely efficient and durable carbon-carbon disc brake system. This allows the car to screech to a halt in a split-second, and allows drivers to use their speedy reaction times to the best of their ability. When the driver steps on the brake pedal, it compresses two master brake cylinders, one for the front wheels and one for the rear, which generate fluid pressure.

For the front tires, the fluid pressure is delivered directly to the front brake calipers (part that houses brake pads and pistons). Inside each caliper, six pistons clamp pads against the disc and it is this friction that slows the car down. For the rear tires it is a bit different.

At the rear, the car can brake by three separate sources: friction from the brakes, resistance from the spinning engine (engine braking) and electrical braking that results from harvesting energy from the MGU-K . Although the driver can adjust each of these on his steering wheel, when he presses the brake pedal, the three systems work together via the Brake By Wire (BBW) system.

When the driver presses the pedal, the fluid pressure generated in the rear braking circuit is picked up by an electronic pressure sensor. The signal from this sensor represents the overall rear braking demand from the driver and is passed to the Electronic Control Unit (ECU) where it is turned into a series of commands to brake the rear of the car. The ECU distributes its efforts to the three systems according to the the set up of the car and this is altered by the way that the driver has adjusted the switch settings on the steering wheel. This is what teams mean when they say changing the setting on the car.

Going hand-in-hand with braking, cooling is another important part of the car, especially for brakes. Basically, there is a series of systems that cools the power unit, brakes, and electronics. If the car overheats, it can lead to damage and lack of performance. There are a few ways to cool. Radiators cool the engine and hybrid system. Intercooler cools the air that the turbocharger compresses before it enters the engine. Brake cooling ducts bring air to the brakes in order to stop them from overheating.

2. Electronics and Sensors

So i'm sure many of you have looked at the steering wheel and been baffled that this thing that looks like a Nintendo Switch steers that car. The F1 steering wheel is incredibly complex and has a variety of buttons, screens, and knobs. For example, on the steering wheel is an area for strat settings, where their plans for all eventualities are mapped out. There is also a rotary knob for MGU-K settings, where drivers can switch around when faced with possible failures. The menu allows drivers control over every setting in the car. Beyond that there is the pit lane speed button, gear change buttons, race start button, energy recovery button, and brake balance knob, among others. It really tells you how much drivers do in a race beyond racing.

Other than the steering wheel, there is also the telemetry, over 300 sensors which gathers race data and sends it back to engineers on the pit wall. This way, engineers can either remotely alter settings and strat, or advise the driver on what to do.  F1 uses a customized mesh wireless network system based on WiMax 802.16 at each racetrack. The sensors record data, which is then temporarily stored in the Electronic Control Unit (ECU), which controls functions like engine performance and power steering. That sensor data then travels wirelessly to a centralized location managed by F1. F1 then sends the data to the relevant team, of course very securely. Teams then use a system called Advanced Telemetry Linked Acquisition System (ATLAS) to view and analyze sensor data.

The final pretty important electronic devices on an F1 car is the many many cameras. The most recognizable camera is found in the "T" structure that sits atop of every F1 car. It gives viewers that top-down, forward facing view used often by broadcasters. this is also how viewers often distinguish between cars of the same team. One driver will have a yellow camera, the other has black. The two nose cameras provides a view of the front wing and low circuit. The 360 camera is on top of the chassis and provides a wide view of the race track, and everything else around the car. The driver facing camera is pointed directly at the driver and helps keep track of how they are doing, and in the event of the crash helps marshals and rescuers figure out the best way to help. The two rear cameras are settled on a rear facing structure, and allows the pit wall to see what is going on directly behind the driver and advise. Beyond these ones, drivers also have cameras inside their helmets, showing exactly what they see. Can't get away with much in an F1 car.

3. How They Work Together

So, we now know the basics of most parts of the car. But these parts all must work together before that car will go anywhere. How do they do it?

One of the more obvious relationships is between aerodynamics and power. The better the aerodynamics, the more usable the power is. They also work in tandem around different parts of the track. On corners the aerodynamics keep the car stable while the power peters off. On straights the power keeps the car boosted. Suspension and tires are also very connected. It is the suspension that keeps the tires on the ground. A good suspension will also mean that the tires are easier to manage, something any driver knows is highly important. Brakes and ERS are also connected because the brakes help recover ERS, pretty simply. Also the cooling system works with most of teh car, cooling engine, tires, and brakes. The biggest connection is probably between all the sensors on the car. They are connected to every single part, and even a small bit of damage can destroy them. The non-sensor components have to accommodate for the sensors and work perfectly with them in order for proper data to be sent back.

The ultimate goal of engineers is to create a car that works in harmony all together. The integration of the engine to the chassis is highly important. There have been cars that the parts were fantastic on their own, but the minute they were put together stopped working completely. Its why teams that produce their own engines have such a leg up over non-manufacturers. Its also why sometimes you will see a car that is running poorly until one small thing is changed, and then suddenly its brand new. Car harmony really is terribly important.

Alright, done! While I covered most of the important stuff, as always if there is any particular part of the car anyone wants me to dive deeper into, please let me know.

Cheers,

-B

BroadWiMAXのメリットは安いことですよね。デメリットはオプションを解約しないと安くならないことでしょうか。あと一度クレカ情報を変更したのですが、その際 payment-change.jp というめっちゃくちゃ怪しいサイトに飛ばされるのもデメリットの一つですかね(^^)

実はもう一つありまして、BroadWiMAX運営会社LinkLifeから何かの勧誘と思われる電話があります。ただ私は知らない番号だったこともあり無視していたら来なくなりましたので、電話に出てもきちんと断われば来なくなると思われます。そのうちまた来るかもしれませんが、料金を考えれば営業活動として大目に見てもいい��なと思えるくらいだと個人的には思っています。これ書いて良かったか分かりませんが怒られたら消せるように念のため別記事にしました(^^;)

Afterword preview

So My RV is your RV, is this what you hoped for, for my part the 6 wheeler is take me to your leader stuff, the 2 wheeler is a bit jilted I guess, for people who don't care what others think, at all, but still fun to have, whereas this 4WD is it, it's everything an expedition vehicle can be, and more modestly

It has an extensive stay capacity with those fridges, and water or energy autonomy wise it's there also, huge trunks too, and a rooftop, bottom line you could be gone for months, and still a reasonable size vehicle, if you're a bit of a hunter and a fisherman that is you know your way around living in the outback I would be tempted to say you could be gone for years, this can really be someone's new home

It's equipped with a hydraulic crane for dealing with difficult terrain and there should be hydraulic tools that you can plug into those lines, double heavy duty windshields that three falling becomes less of an issue plus the roof has strong steel rails, heavy duty doors with PIN locks to keep your close ones and belongings safe, satellite internet for keeping in touch and in case of emergencies, it turned out to be everything it could be and it's a lot

The one point where someone could say it's nice but, is having to tank on gas ie the autonomy part is only in theory not in practice, we have skipped on gas, filling water tanks should be feasible anywhere where you have water flowing, differently than stale, no it's it really

I would bet that every modern quality radio does 3 band and GSM, the PDA's that we have seen are not only radios

Because the RV is equipped with 3G antennas videolinks say with a distant camp become possible, in the wilderness, it's movies stuff but incredibly it does that also, whether these are going to be options for those who want them or not is past the point that it's possible

You need 3 antennas to triangulate a GSM signal, I would have a fixed antenna that I set up with as much open space around as possible, and another portable antenna at the camp and that's 3, or why not have 2 vehicles and a portable antenna at the camp, there's possibilities

I still have to look into what's the range of those, I know there's other stuff such as WiMAX, which is directional however
