ABSTRACT:
An apparatus for minimizing current drain in a battery powered data collector includes a stimulus device. In response to receipt of a first state of a control signal, the stimulus device provides a periodic stimulus signal. In response to receipt of a second state of the control signal the stimulus device ceases provision of the signal. A switch device is coupled between the stimulus device and a load. When the switch device is in an on-state, and the signal is provided from the stimulus device, the switch device provides the signal to the load causing depletion of energy from the battery into the load. Responsive thereto the switch device provides the second state of the control signal to the control input of the stimulus device, that then ceases the provision of the signal to the load thus ceasing the depletion of the energy from the battery.
