Thermopneumatic Pixels for Fast, Localized, Low-Voltage Touch Feedback

CoRR
We present thermopneumatic pixels (TPPs), which are tactile actuators designed for rapid fabrication and straightforward integration into compact wearable and surface-based haptic systems. Each TPP converts low-voltage ($\sim$10 V) electrical pulses into transient pressure increases within a sealed cavity, producing out-of-plane forces and ...

Strengthening of grid – Assessment of touch voltage and short circuit performance

Denne bacheloroppgaven undersøker tekniske og driftsmessige tiltak for å styrke et 22 kV distribusjonsnett. Oppgaven er skrevet på vegne av et nettselskap og tar utgangspunkt i et reelt kraftnett. Av hensyn til kraftsensitiv informasjon er nettselskapets navn og deler av nettinformasjonen utelatt i rapporten. To hovedutfordringer i nettet er undersøkt.
