Fuel gauge eliminates battery characterisation to speed time to market
Incorporating an algorithm that converts raw measurements like battery voltage, current and temperature in state of charge (%), absolute capacity (mAhr) and time-to-empty, time-to-full (while charging) values, the ModelGauge m5 standalone fuel gauge has been announced by Maxim Integrated.
LDS technique shapes up for next-gen wireless antennae
In co-operation with the Institute of High Frequency Technology and Radio Systems (Institut für Hochfrequenztechnik und Funksysteme, HFT) at Leibniz University of Hannover, the LPKF Laser Direct Structuring (LDS) technique is currently being evaluated for suitability for next-generation wireless applications. Early indicators are that LDS technology is applicable for antennae in the millimeter-wave frequency band, e.g. 5G wireless technology or for automotive sensors.
