    摘要: A system for boiler control is provided. The system includes supply units to provide supplies of combustion materials for combustion thereof, a vessel coupled to the supply units in which the combustion materials are combusted, a carbon monoxide (CO) sensor disposed at an outlet of the vessel to sense a quantity of exhaust CO output from the vessel as a product of combustion therein and a control unit. The control unit is coupled to the supply units and the sensor and configured to issue a main servo command and a pulse servo command to one or more of the supply units to control operations of the one or more supply units in accordance with the sensed quantity of the exhaust CO.

    摘要: A security system (20) includes a plurality of sensors (22-26) that provide an indication of a security condition to a corresponding plurality of microcontrollers (32-36). Each microcontroller communicates information regarding the security condition to a central control (40). The communications from the microcontroller include using an elliptical public key encryption for protecting a key associated with the security condition information. In a disclosed example, the security condition information is encrypted using a symmetrical encryption technique.

    摘要: An exemplary method of communicating with a safety device includes obtaining a key from the safety device that is useable for only a single communication session with the safety device. A plurality of messages are sent to the safety device during the single communication session. Each of the plurality of messages includes the obtained key, an identifier of the source of the message, an identifier of the safety device, a sequence number indicating how many of the plurality of messages preceded the message during the communication session, a command for the safety device, and at least one cyclic redundancy code (CRC) based on content of the message. A next one of the plurality of messages is sent only after confirming that the safety device has accepted a most recently sent one of the plurality of messages.
