Abstract: In this controller, a manipulated variable is produced as a sum of a linear compensation term and a product term, the compensation term being a linear combination of a contouring error and its time derivatives, and the product term being formed by multiplying a fuzzy control term by a saturation term. This controller combines the advantages of the sliding-mode controller with boundary layer and those of the fuzzy controller, and thus represents a robust controller for a wide class of nonlinear nth-order systems.

Abstract: A system for marking an edge of a mailing piece with a desired indicia, thereby permits identification of the marked mailing piece when the marked mailing piece is stacked with other mailing pieces, usually similar mailing pieces. A computer directs which mailing piece is to be marked and activates the marking process. A group of computer controlled solenoids, with each solenoid linked to an indicia imprinting marking pad, is activated for the edge marking. Each activated solenoid forces the marking pad against the mailing piece's edge thereby marking the edge of the mailing piece.

Abstract: A plant (72) is operable to receive control inputs c(t) and provide an output y(t). The plant (72) has associated therewith state variables s(t) that are not variable. A control network (74) is provided that accurately models the plant (72). The output of the control network (74) provides a predicted output which is combined with a desired output to generate an error. This error is back propagated through an inverse control network (76), which is the inverse of the control network (74) to generate a control error signal that is input to a distributed control system (73) to vary the control inputs to the plant (72) in order to change the output y(t) to meet the desired output. The control network (74) is comprised of a first network NET 1 that is operable to store a representation of the dependency of the control variables on the state variables. The predicted result is subtracted from the actual state variable input and stored as a residual in a residual layer (102).

Abstract: Each design data of intarsia, jacquard, and structural stitches is separately stored and independently processed. Each design data is stored in an internal data format where one pixel is allocated to each loop and is compensated for the aspect ratio of loops by affine transformation before being displayed on a monitor. Similarly input coordinates from a stylus are inputted in a coordinate system corresponding to the internal data format and then converted into monitor address with coordinate affine transformation.

Abstract: Adaptive control of a system with a human in the loop is accomplished by sensing human operator reactions to a disturbance in the system and characterizing the operator response to the disturbance. The operator response is characterized in one of several forms by predicting a response based on a model quantifying a response based on statistics or merely measuring a response for accumulation of data to be employed by an artificial intelligent system. The disturbance which provides the human operator reaction, is applied or occurs naturally based on other stimulus and is measured by the system. Quantifying the results of the disturbance and the operator response comparison allows selection of a control mode by identifying one or more categories of reaction response or a graduated modification of the control law employed in the system. Various modes or categories for control of the system incorporate different sensitivities on a macro scale or an entirely different control algorithm.

Abstract: A computer-based engineering design system to design a part, a tool to make the part, and the process to make the part. The design system has a processor and a memory. The memory stores feature templates, each feature template being a representation of a primitive object having a form and a function. Each feature template is indexed by the function of the primitive object and includes a representation of a primitive geometric entity having the form of the primitive object. Each feature template can include information relating to a tool to make the primitive object and a process to make the primitive object. The design system also includes an input device for receiving a request to design the part. This request includes one or more predetermined functions that the part performs.

Abstract: A process is disclosed for controlling a production machine, in particular an injection moulded machine that produces injection moulded plastic parts. During a learning cycle, rating fields that indicate the relationship between selected quality parameters of the products and selected setting parameters of the machine are determined and stored. To allow the machine to be controlled by entering the actual target values, i.e. the quality parameters of the products, the set values or set value ranges for at least two selected quality parameters are entered into a control device. The control device then determines at least one set of selected setting parameters on the basis of the stored rating fields, all predetermined quality parameters simultaneously corresponding to the predetermined set values or lying in the predetermine set value ranges.

Abstract: An automatic library system for providing computer access to data carriers therein includes a store for the data carriers, and at least one read/write station for the data carriers having an in/out opening. An intermediate store is arranged adjacent the in/out opening for an intermediate storage of the data carders in at least one intermediate storage position. A controller is provided which is capable of initiating transportation of one of the data carders directly from said store to the in/out opening or from the store to the intermediate store. The controller is also capable of initiating transportation of one of the data carriers stored in the intermediate store to the in/out opening of the read/write station upon a request for the one of the data carders by the computer. In such a manner, operational delays for the automatic library system are significantly reduced.

Abstract: The present invention relates to a control solution development environment coupled to a runtime environment constructed to insulate the control solution designer as well as the developed control applications from both the hardware and the operating system. This insulation frees the designer from having to deal with a tangle of control and operating system commands and considerations. The runtime environment manages the details of the process system resource and task allocation to implement the control strategies. Since the runtime environment insulates the developed control applications from changes in operating systems and hardware, applications developed to run in this environment are both reusable and portable. The runtime environment is scaleable, fault-tolerant, allows dynamic reconfiguration of the system, integration of diverse sensors and actuators and enables distributed control strategies.

Abstract: A computer controlled separator device is disclosed. The computer control system monitors the operation of the separator device and makes any adjustments necessary to maintain optimal operation. An operator may input values representing desired operating parameters and/or desired product characteristics of the separator device. Alternatively, these values may be programmed into the computer control system in accordance with optimal product or system standards. The computer control system monitors the operation of the separator device and makes any adjustments necessary to maintain operation in accordance with the selected or programmed values. Specifically, the computer control system may monitor incoming and outgoing product characteristics, i.e. particle weight, particle density, or particle size; and/or operating parameters, i.e. air flow, vibration speed, side tlit, end raise, feed rate, divider knife position and cutout gate position.

Abstract: Extended error protected communication system.An extended consumer communication system uses a signal that is error protected by a block code. The generator polynomial isG.sub.n (x)=g.sub.o (x) . . . g.sub.n (x)which is factorizable, and each of the factors implement a linear and systematic code. Generally, each of the factors adds redundancy and raises the level of error protection. In this way, redundancy that is associated to a later term of the sequence occupies code positions that are protected by at least one earlier term in the sequence and may in consequence be used for positioning data that is protected by such earlier term, upon surrender of such higher protection level.

Abstract: Apparatus for transmitting and receiving information blocks, particularly video information, is arranged so that on receiving a corrupted information block it stores a first receiver buffer address at which the data block should be stored if subsequently successfully repeated in a later information block. The apparatus keeps track of the time taken to receive a requested repeat information block and on receiving the later information block at the predicted time, and on determining that it is uncorrupted, stores the data in the receiver buffer at the stored buffer address. Such apparatus can allocate received, repeated and non-repeated data blocks to their correct relative positions within the receiver buffer without the need for numbering of the data blocks on transmission giving a consequential reduction in the size of the data blocks being transmitted.

Abstract: When an ingot is sliced into wafers, they are given serial numbers for identification. This makes possible to identify which any wafer being processed is of those sliced from the ingot no matter where the wafer is in a manufacturing process. Each wafer is traced so as to determine the path along which the wafer was transferred during the manufacturing process, and results are stored as wafer information.

Abstract: A hierarchical control PLD system controls deposition processes by feedback means, for industrial production of tribological thin films. PLD process system identification, intelligent feedback control architecture, and implementation for ultraviolet pulsed laser deposition processes are provided. This system has three levels of feedback control. The first level of feedback control improves the precision and tracking of sub process variables by linear observer based compensator control. The Mo I plume species density per laser pulse and bulk substrate thickness by the quartz crystal micro balance provide real time sub process data to the observer. The observer based compensator then directly calculates laser energy density per pulse and pulse repetition rate based on the current values predicted by the linear model. The second level consists of a dynamical system design algorithm and nonlinear process map.

Abstract: One data transmitter for transmitting a broadcast data onto an outside data bus and data receivers, whose number is "n", for individually receiving the transmitted broadcast data are provided. A single error signal line is connected in common to the data transmitter and each of the "n" data receivers. Each of the data receivers notifies an error detection to the data transmitter and the other data receivers via the error signal line with a wired OR connector when its own data receivers detects an error. Being notified of the error detection, the data transmitter re-transmits the data so that all of the data receivers re-receive the data. Accordingly, re-transfer per one data at a broadcast transfer is contemplated.
