  • Patent number: 6472008
    Abstract: The present invention comprises a batch sterilization system, a controller for use in the batch sterilization system, and a method performed by the controller. The system, controller, and method are used to administer and provide on-line correction of a batch sterilization process performed on a batch of containers. The controller compiles an actual retort time-temperature profile during the batch sterilization process from the actual retort temperatures sensed by a sensor. While this is occurring, the controller controls a batch sterilizer so as to administer an initial portion of the batch sterilization process before a temperature deviation has begun according to a scheduled time-temperature profile. This temperature deviation is between the actual retort time-temperature profile and the scheduled processing time-temperature profile.

  • Patent number: 5548781
    Abstract: A data communication apparatus and associated method for switching from the Compatible mode to the ECM mode. The data communication apparatus receives a protocol message transmitted by a second data communication apparatus in accordance with a Compatible mode of operation. The first data communication apparatus then inverts the polarity of the received protocol message so that the inverted polarity protocol message is formatted in accordance with a G3 mode of operation. Then, the first data communication apparatus determines from the inverted polarity protocol message that the second data communication apparatus will receive the image data if it is transmitted in accordance with an ECM mode of operation. The image data is then transmitted in accordance with the ECM mode of operation to the second data communication apparatus.

  • Patent number: 5548649
    Abstract: A network local security bridge and corresponding method for bridging a first side of a network and a second side of the network. The first side includes local secure zone host devices within a local secure zone established by the network local security bridge. The second side includes remote secure zone host devices within remote secure zones established by network remote security bridges. The network local security bridge processes a first side data packet received from the first side of the network and a second side data packet received from the second side of the network.
