Electrical Testing TRIZ Cases
- Wire Bundle Current Shunt for High Frequency Measurement
Segmented wire bundles reduce inductive drops and skin effect errors for accurate high frequency measurement.
- Digital Backup Signal Circuit for Load Control
A load-control backup signal generation circuit uses a pulse count unit and digital comparator to produce rapid control signals.
- Battery Monitor Correcting Internal Resistance Errors in Parallel Strings
Calculating intercell current compensates for leakage paths and distribution errors in parallel connected battery strings.
- Recording Original Battery Model Data in Reused Cells
A reused secondary battery management system records original model data in the cell to enable accurate identification during reassembly.
- Scan Clock Control Circuit for Semiconductor Noise Reduction
Shift clock control circuit distributes switching noise across rising and falling edges, reducing peak interference without extending test duration.
- Battery Resistance Indicator for Mobile Terminal Power Management
A mobile terminal system calculates battery resistance from no-load and full-load voltage measurements to indicate remaining power.
