摘要： A voter subsystem for a multiple node fault tolerant system having an upper medial value sorter for sorting a plurality of received values to generate an upper medial value and a lower medial value sorter for sorting the same plurality of received values to generate a lower medial value. An averaging circuit adds the upper and lower medial values then divides by two to generate a voted value. A deviance checker checks each of the plurality of received values against the voted value to generate a deviance error for each received value which differed from the voted value by a predetermied amount. A loader loads the plurality of received values into the upper and lower medial value sorters and the deviance checker bit-by-bit, starting from the most significant bit positions through the least significant bit positions. The upper and lower medial value sorters and deviance checker process the received values on-the-fly in the order they are received.

摘要： An operations controller for a multiple node fault tolerant processing system having a transmitter for transmitting inter-node messages, a plurality of receivers, each receiving inter-node messages from only one of the nodes and a message checker for checking each received message for physical and logical errors. A fault tolerator assembles all of the errors detected and decides which nodes are faulty based on the number and severity of the detected errors. A voter generates a voted value for each value which is received from the other nodes which is stored in a data memory by a task communicator. A scheduler selects the tasks to be executed by an applications processor which is passed to the task communicator. The task communicator passes the selected task and the data required for the execution of that task to the applications processor and transmits the data resulting from that task to all of the nodes in the system. A synchronizer synchronizes the operation of its own node with all of the other nodes in the system.

摘要： A task scheduler for a fault tolerant multiple node processing system having a task activity list storing a set of application tasks, a priority scan list storing a selected portion of the set of application tasks, a completion status list also storing the same selected portion of the set of application tasks. A wake-up sequencer transfers the application tasks from the task activity list to the priority scan list, and a priority scanner transfers the application tasks ready for execution from the priority scan list to a selection queue. A next task selector selects the next application task that its node will execute, and a task started register stores the identity of the application tasks completed by the other nodes. A task interactive consistency (TIC) handler updates the status of the application tasks stored in the task activity list, the priority scan list, and the completion status list in response to messages received from the other nodes identifying which nodes completed tasks. The task interactive consistency handler checks the scheduling process of each node by comparing the application tasks it reported to have started with the highest priority application task scheduled for that node in its selection queue.

摘要： A method and apparatus for determining the sufficiency of the refrigerant charge in an air conditioning system by use of temperature measurements. The temperature of the liquid refrigerant leaving the condenser coil and the outdoor temperature are sensed and representative electrical signals are generated. The electrical signals are converted to digital values that are than compared to predetermined optimal values to determine whether the system is properly charged with refrigerant. An appropriate LED is lighted to indicate that the system is undercharged, overcharged or properly charged. For non-TXV/EXV systems a third parameter i.e. the return air wet bulb temperature is also sensed and a representative digital value thereof is included in the comparison with the predetermined known values to determine if the charge is proper.
