On this episode you made mention of the automotive EMC requirements, and that it was generally self certified; I work for JLR (Jaguar Land Rover) in the UK as a EMC Test Engineer on components. the main international standard for testing whole vehicles is Reg 10 (UNECE Regulation 10).
Components are tested individually to an internal standard “JLR-EMC-CS v1.0 Amendment 4 – EMC Compliance Specification For Electrical/Electronic Components and Subsystems” (https://skippy.org.uk/jlr-emc-cs_v1-0_amendment_4/)
The limit lines in this standard are inline with equivalent international emission and immunity standards as you mentioned, however in general the limits are overall more onerous.
The company where I am working in builds special purpose vehicles for mountain farmer and municipal purposes.
We have several numbering systems.
There are three major systems:
All of them use 9 digits and/or letters
1.: The system for the parts and that used in our products
There are 9 digits.
The first three digits indicate the product group.
The second three digits indicate the assembly-group.
And the last the digits are a random number.
The most fun are parts which are used in multiple product & assembly groups.
This numbers get generated in the CAD-System of the construction office
2.: The system for bought parts like screws, tools and so on.
This numbers are 9 digits too.
The first three digits are 999.
The next three digits show the product class.
And the last three digits are random.
If the number group of the last three digits are full, a new product class gets added.
And if we ever run out of product classes, the 999 designator gets decreased to 998 and so on.
This numbers get generated in the merchandise purchase office
3.: The numbers for devices and fixtures
This numbers starts with 3 letters and have a 6 digit number
The first letter starts with a V (German for Vorrichtung -> device / fixture)
The next two letters indicates the purpose.
(If it’s a welding fixture, milling fixture, press fixture,…)
And the next 6 digits is a continuous number.
It’s possible to estimate the age of the device / fixture and if you should bother to search within the CAD system or should go straight to the archive catacombs to get the dead tree version of the drawing.
This numbers get generated in the CAD-System of the device construction office
The numbers of the bought parts have no version indicators.
The produced parts and device/fixture parts uses letters and digits as version/revision indicators.
As long the part is in the test-phase, letters from A to Z are used.
If a design engineer ever reaches Z he gets a little tapping on his shoulder from the device construction office and has to pay his share to the summer holiday festival.
And if a device / fixture design engineer ever reaches Z he gets a little visit from the device production.
When the part reaches serial status, the version indicators get switched to digits.
A new version number is needed as soon the part gets changed.
The reason is that the part has to be linked to drawings, CNC-programs, measure machine programs, devices / fixtures and so on.
If the part gets changed without revision, no one gets the chance to adapt everything to the changes.
Changed parts without new version number could easy lead to 4 to 5 digit costs or more.
Hey Chris,
The CFO of Huawei was arrested, on request of the US government, in Vancouver and is still in Vancouver. She has not been deported. She is being charged for circumventing sanctions against Iran by setting up a shell company to ship embargoed equipment to Iran.
While creating an international situation, the US gov then dragged its feet for months when deciding whether to extradite or not, leaving Canada in a shitty situation. (Then the US put on the aluminum and steel tariffs to thank us for being their ally and best trading partner and doing a great job at collaring their perp)
The US finally decided to go through with the deportation process, somewhat after China decided to arrest two Canadians for no declared cause, and to retry another for drug smuggling so that he could get a death sentence. (just say no kids)
Recently trump decided that if the US gets a good trade deal out of China, they’ll drop the charges against the CFO and drop the bans of Huawei equipment. International law says that deportation cases like this one can’t be meddled with by politics and trade deal outcomes, so this isn’t going to end because of selling a few Jeeps in Shanghai.
The Canadian gov is playing this one clean. The CFO is being processed without political influence (even though the Chinese told our Prime Minister to make this go away if he knows what is good for him) to see if the US has a case for deportation, but this takes time and the case is to go to court in early 2020.
In the meantime, Chinese ambassador to Canada, Lu, will depart the country at the end of this month, after warning of “repercussions” and calling Canada white supremacists for siding with the US.
Governments all over the world are being told to ban Huawei 5G infrastructure equipment or be ready for another export tariff fight. Companies all over the world are being told to not sell Huawei anything or be banned from selling to the US. Huawei was one of STMicroelectonic’s top 5 accounts. ARM sells a lot of IP, they have to protect their interests.
This shit is hitting a very big fan and everybody is getting covered with it.
Interesting that you are worries about the app store.
Cuz Google is never available in China. So people are use to getting apk themself from internet. But also, many manufactur have their own stores and they buck upload apks onto it.
Even apps from google play could have apk extracted from it. So that’s actually not hard.
The things people are exicting about is making some system that’s not andriod, get rid of the google side of things. But also able to use andriod app directly.
Adding on to my own post, for any interent things, China basically have a alternative for anything. So another andriod? Sure.
