Apparatus for measuring the weight of small items
The apparatus has forceps (14) with a proximal portion holding a selected object and distal portion. A solenoid plunger (28) strikes the forceps for initiating vibrations upon application of an electric pulse. An optical system measures the oscillating frequency of the forceps holding the object and...

| Zusammenfassung: | The apparatus has forceps (14) with a proximal portion holding a selected object and distal portion. A solenoid plunger (28) strikes the forceps for initiating vibrations upon application of an electric pulse. An optical system measures the oscillating frequency of the forceps holding the object and compares the measured frequency with an oscillating frequency of empty forceps to compute mass and weight of the object. |
