This paper presents a model to estimate the rate of capacity utilization (CU) in the manufacturing sector by state. Consistent measures of state-level CU rates have been unavailable since 1982. The ...

Consumers and designers of portable systems increasingly want to know the remaining capacity of their battery as precisely as possible. They also want warnings to signal when to change the battery to ...

High-capacity, multilayer ceramic capacitors (MLCC) have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon ...

This simple charger and capacity tester, which is built around two inexpensive and widely available modules, provides an ...
