    Abstract: A reconfigurable appliance control system includes a dedicated appliance control (DAC) for controlling operation of an appliance. The syste m further includes an appliance communication control (ACC) for communicating with at least one appliance. The system includes an appliance communication connection for interfacing the ACC to the appliance. The system also includes an external host control (EHC) for communicating with a remote system. The system further includes a host communication connection for interfacing the external host control wi th the ACC.

    Abstract: A remote operation management system for commercial appliances is provided. The system includes a user interface for authorizing use of an appliance and a dedicated appliance controller coupled to the user interface and the applian ce for controlling operation of the appliance. An appliance communication controller is coupled to the user interface over an appliance communication connection, and an external host controller is coupled to the appliance communication controller over a host communication connection. The external host controller is configured to communicate a message for the appliance to the appliance communication controller. A remote management system is coupled to the external host controller and configured to control a function of the appliance.

    Abstract: A digital data detector (27) is part of the primary side control electronics in a high voltage integrated circuit for regulating a power supply secondary side output potential; the detector output (27a) is responsive to the transitions of digital error data received from the supply secondary side via an electrically-isolated data transmission means. Only the transition edges are utilized by the detector, so that any non-linearity after each transition of the transmission means is immaterial. If the isolation device is a pulse transformer (17), the transformer core can be of relatively small volume, as full-pulse reproduction is unimportant and pulse saturation is tolerable. A multiplexer (33) allows the primary side control electronics to initiate power supply operation; control is switched to the secondary side responsive to signal edges therefrom being detected by the digital data detector.

    Abstract: A microprocessor-based relay system is used in combination with relay contactors and a control circuit therefor to protect an electric motor from overload currents in addition to phase faults, ground faults, load losses, and load jams. The microprocessor is provided with a data base comprising thermal characteristics of the motor during heating and cooling. The heating data comprise current versus time curves stored as a look-up table for which each data point represents a thermal limit, i.e., the maximum time the motor is permitted to operate at a particular current level. The cooling data comprise motor cooling rates. Phase currents are sampled at preselected fixed time intervals during a predetermined period thereof, and an average motor current value is calculated therefrom. A thermal sum, which is initialized at zero upon first starting the motor, is adjusted depending on the average motor current value relative to a predetermined overload current value. The average motor current value is used as an index to the heating curve look-up table. If the thermal sum exceeds the corresponding thermal limit in the look-up table for a predetermined time interval, then an overload condition is indicated, and the relay is tripped.
