Latest Patents

**Electrical Signal Taking-Out Device.** This invention describes a device designed to reduce the effects of external electromagnetic waves and help obtain reliable waveforms and measurements. It uses a pair of metal wires held by a metal retaining member. An actuating mechanism opens and closes the wires’ gripping ends, while the retaining member provides a path for signals to measuring equipment.

**Electrical Signal Read-Out Method and Device Therefor.** This method and device are intended to take measurements from the opposite ends of a chip component soldered to a circuit board. Two contact elements with inward-bent, sharp tips are positioned to face each other. A holding member moves the tips into the solder joints and keeps them in place, allowing signals to be taken independently from each contact.
