Abstract: A distributed digital rule processor to create a single system image (SSI) on a cluster of von Neumann processors. The rule processing engine has a group of digital rule nets each having their own local bindery and local controllers which are interconnected by a global bindery. Slave translators are interfaced to the global bindery to receive rule calls from the rule nets and return statuses. A compiler maps the typical source code instructions into groups of rules which are stored in the rule nets' storage area. The rules contain groups of input variables and output variables. The output variables of a calling rule become the input and data for the called rule. Slave application processes on the von Neumann processors perform slave activities for the slave translators, as the rule nets are unable to manipulate data. Rules received from the rule nets by slave translators are processed and processed data or return statuses are sent back to the nets for further instructions.

Abstract: A control unit for a combined ceiling fan and light fixture (ceiling unit) is coupled to a temperature sensor monitoring the temperature of the room containing the ceiling unit, has manual entry keys for controlling fan energization, speed and direction and light energization and intensity and for selecting a mode of operation, and has a first microprocessor for controlling a radio transmitter to transmit a command bit sequence. The transmitted signal is received by the ceiling unit where a second microprocessor responds to the command bit sequence to control the firing of one of several triacs controlling fan energization, speed and direction and to control light energization and intensity. In an "auto-speed" mode, fan speed responds to changes in room temperature. In a "winter mode", the fan blows upwardly at a slow speed, the speed being momentarily increased periodically to break up stratification.

Abstract: A control system for operating at least two electrical appliances, such as a combination ceiling fan and light assembly, from a remotely located multi-position manually operated switch assembly. The system responds to a series of different control signals actuated by the different switch positions to switch either one of the appliances on or off, to control the intensity of the light or the speed of the fan, or to initiate any one of a series of pre-programmed sequences of operations of the appliances.

Abstract: Circuitry for applying electrical power to one or more load devices under control of a remotely located manually operable switch coupled to the circuitry by a single power transmission line. The circuitry responds to toggling of the remotely located switch to, for example, in a first state apply power to a first load, in a second state apply power to the second load, and in a third state apply power to both the first and second loads.

Abstract: A package terminal air conditioning system as disclosed having a room air-circulating blower, an air-cooling device, an air-heating device, and a thermostatic control which governs operation of the air-cooling and air-heating devices in response to the temperature of room air which is circulated by the blower.The control unit senses the temperature of the air which is returned to the unit from the room and the air which is discharged from the unit to the room and operates an appropriate electrical switch to enable and disable the respective air-heating and cooling devices. The operation of the unit is such that when the temperature of the discharged air differs substantially from the temperature of the return air, the differential in the sensed room air temperature between the cut-in and cut-out of the heating or cooling device is reduced which results in minimizing the possibility of overheating or undercooling the room.
