Lithium-ion batteries, like other battery types, are subject to a process of wear and tear during charging and discharging due to chemical changes.
Without battery balancing, the weakest cell in a multicell battery always determines the capacity of the entire system. However, since individual cells age differently,...

It is apparent that many older specifcations for government and military security contacts were based around the misconception that Balanced Magnetic Switches (BMS) or Triple balanced reed switches provide the highest possible security. While it is true that BMS / Triple balanced reed devices do provide “better”...

In the early 90’s, it was suggested that Charge Coupled Devices (CCDs) were in the process of becoming extinct and considered to be ‘technological dinosaurs’. The prediction is not entirely wrong, if the announcement made by Sony in 2015 is taken as an example.
Sony Corporation has officially announced...
