Flex circuitry for next-level embedded design
There are two aspects associated with flex circuit bending: one is static or one-time bending, the other is dynamic flex…
IoT security: Why X.509 is not always the best choice
X.509 certificates make a solution more secure, but using it greatly complicates a design if client-side certificates are required.
Extracting X.509 certificates from devices
X.509 certificates provide strong authentication, but in a practical set-up, other mechanisms such as username/password can be just as secure.
IEEE EMC 2016: Shielding materials
Precision expanded foils are used in wherever mesh and perforated foils with high precision mechanical and electrical properties are required.
Compliance test tools: LISNs and antenna masts
The mast is weather-proof, with all metal elements located in the base plate and the drive mechanism only maximum 0.4m…
Troubleshooting tools: scanners and current probes
The EMxpert system lets PCB engineers find, characterise and address unintended radiators or RF leakage areas.
10 views from the IEEE EMC 2016
Those who make EMI/EMC measurements for debugging, will find the RTO/RTE oscilloscopes quite useful.
Tele-haptics close the ‘feel’ gap
Good tele-haptics go way beyond force-feedback or the tiny motors generating the tiny vibration we get on our phones.
Can Apple make you upgrade?
Perhaps the biggest Apple news is the elimination of the legacy 3.5mm analog microphone-and-headphones port.
Testing toroidal cores for inductance decline vs DC current
The inductor with the lowest initial permeability core and the greatest number of turns shows the least decline of inductance…
