A controller is configured to receive from the sensors data representing the monitored conditions and to process this data, determining operating information related to the sealing operation and possibly fault conditions with the sealing operation. The controller is also configured to communicate with a display system and to cause this display system to activate one or more peripheral devices in order to report to a system operator, for example, the determined operating information and/or fault conditions related to the monitored conditions. In reaction to a detected fault condition, the controller may also be configured to shutdown the cap sealer system and/or to remove work pieces that the controller has determined contain a faulty condition. ## Claims ### Claim 1 An automated sealing system that performs a sealing operation to install foil seals on work pieces comprising: a sealer to apply energy to seal a foil seal onto a work piece; and a plurality of sensors each for monitoring a respective condition related to said sealing operation of said system, said plurality of sensors including at least a temperature sensor for monitoring a temperature of a work piece after application of energy to the work piece, and a speed sensor for monitoring a speed of said work pieces passing said sealer. ### Claim 2 (depends on 1) The system according to claim 1, wherein at least another of said plurality of sensors is either a laser emitter-receiver or a photo eye for monitoring a position of a cap on a work piece prior to application of energy. ### Claim 3 (depends on 1) The system according to claim 1, wherein at least another of said plurality of sensors is a foil detector for monitoring a missing foil on a work piece prior to application of energy. ### Claim 4 (depends on 1) The system according to claim 1, wherein at least another of said plurality of sensors is a photo eye for monitoring a stalled work piece under said sealer. ### Claim 5 (depends on 1) The system according to claim 1, wherein at least another of said plurality of sensors is a current sensor for monitoring a power drawn by said sealer. ### Claim 6 (depends on 1) The system according to claim 1, wherein at least another of said plurality of sensors is a photo eye for detecting work pieces passing said sealer. ### Claim 7 (depends on 1) The system according to claim 1, further comprising a display system to report data relating to said conditions. ### Claim 8 (depends on 7) The system according to claim 7, wherein said display system includes a text display system to visually report data representing said conditions. ### Claim 9 (depends on 8) The system according to claim 8, wherein said display system further includes a plurality of LEDs to visually report data representing said conditions. ### Claim 10 (depends on 9) The system according to claim 9, wherein said plurality of LEDs includes a set of LEDs to report power drawn by said sealer. ### Claim 11 (depends on 1) The system according to claim 1, further comprising a controller and an electronic memory, wherein said controller is configured to receive from said sensors data representing said conditions and to determine a fault condition based on a pre-stored parameter stored in said memory. ### Claim 12 (depends on 11) The system according to claim 11, wherein said pre-stored parameter relates to the temperature of said work piece after application of energy. ### Claim 13 (depends on 11) The system according to claim 11, wherein said pre-stored parameter relates to the speed of said work pieces. ### Claim 14 (depends on 11) The system according to claim 11, wherein said pre-stored parameter relates to an upper limit of determined fault conditions. ### Claim 15 (depends on 11) The system according to claim 11, further comprising a work piece reject system, wherein said controller is configurable to activate said work piece reject system in response to a fault condition. ### Claim 16 (depends on 11) The system according to claim 11, further comprising a light wherein said controller is configurable to operate said light in response to a fault condition. ### Claim 17 (depends on 11) The system according to claim 11, further comprising an audio alarm wherein said controller is configurable to operate said audio alarm in response to a fault condition. ### Claim 18 (depends on 11) The system according to claim 11, further comprising a shut-off relay to shutdown said sealer, wherein said controller is configurable to activate said shut-off relay in response to a fault condition. ### Claim 19 (depends on 11) The system according to claim 11, further comprising at least one set of one or more pre-stored parameters, said set being stored in said memory, wherein said controller is configurable to determine a fault condition based on said one or more pre-stored parameters. ### Claim 20 (depends on 1) The system according to claim 1, further comprising a temperature sensor and a safety cover sensor for monitoring the temperature of said sealer and for monitoring the removal of a safety cover from said sealer.
