  • Patent number: 4696359
    Abstract: An electronic weighing apparatus providing accurate weight using a low level power supply. A force responsive strain gauge having a high impedance, provides an electrical output to a sample and hold circuit. The signal from the strain gauge is conditioned by a sequencing circuit which turns the strain gauge and sample and hold circuit on and off at a rate providing a very low duty cycle to keep power consumption to a low level. Power is supplied by a photo-voltaic panel built into the electronic weighing apparatus responsive in light levels as low as 50 lux.
