Abstract

Provided is an apparatus, system, and method for detecting a metal contaminant in a sensor-enabled dose form. According to the method, a sensor-enabled dose form is oriented in a predetermined orientation. The sensor-enabled dose form is received through an aperture of a metal detector. A detection signal is generated by the metal detector in response to receiving the sensor-enabled dose form through the aperture of the metal detector. The detection signal is compared to a predetermined threshold. The presence of a metal contaminant in the sensor-enabled dose form is determined based on the comparison of the detection signal and the predetermined threshold. In another method, the sensor-enabled dose form is first oriented in a first orientation and then in a second orientation. The apparatus includes a guide, a metal detector, and a comparator circuit. The system further includes a controller to reject contaminated sensor-enabled dose forms.
