Patent ID: 8645084

Claim:
A method of detecting, monitoring or characterizing a drug tablet comprising of one or more components/parts during compaction comprising the acts of: forming a tablet from a core comprising powder or other solid components in a compactor; transmitting a first set of acoustic waves into said core while said tablet is being formed; receiving a second set of said acoustic waves from said core while said tablet is being formed; measuring data received from said received acoustic waves; coupling devices that transmit and receive and devices that measure said data within instrumentation and signal processing system; using said instrumentation and signal processing system for transmitting/receiving said data with wire and/or wireless means; using a computer for calculating said data; presenting said calculated data on a display device; and transmitting said calculated data after processing to a control unit of said compactor as process feedback with wire and wireless means, wherein said method determines a quality level of said drug tablet and/or a defect state of a tablet from said calculated data.
