Abstract: Abstract of the Disclosure:         Apparatus   and   methods  for   producing intermittent, discrete patterns of coating material, such as hot melt adhesive, onto discrete substrates or substrate areas, where the patterns have sharp, square leading and trailing edges, as well as side edges.  A slot nozzle die has elongated air slots along the slot extrusion opening.  In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow   Also, the air flow is continued beyond that point in time, when the hot  melt  flow  ceases.    The  delays  between  the operations of the air flow and the hot melt flow are on the order of micro seconds.  Coating weights down to 1 gram  per square meter at about 350 meters per minute substrate speed are provided.  Alternatively, the lead and lag air start and stop times on each side of the coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE A transmitter receives power over a two wire current loop. The transmitter includes a first capacitor which is charged to a reference potential so as to generate a reference charge packet and a second capacitor which is chargedto a sensor potential so as to generate a measurement charge packet. The sensor potential is representative of a process variable to be measured by the transmitter. The reference potentials are selected. from a first and second reference potential, each of a polarity opposite the other. The transmitter also includes an integrator which provides an output representative of a time integral of the charge packets. The transmitter also has a plurality of switches formed in a semiconductor substrate. Each switch has a semiconductor junction between a terminal on the switch and the substrate. When the potential at a switch terminal has a magnitude large enough to forward bias the junction, the switches leak charge. A comparing circuit in the transmitter actuates the switches to transfer reference charge packets of one polarity and measurement charge packets to the integratingcircuit until the integrating output crosses a threshold potential and thereafter to transfer a reference charge packet of the opposite polarity and a measurement charge packet to the integrator, such that the potential at a switch terminal is less than the reference potentials.

Abstract: A neural network is trained with a general set of data to function as a general model of a machine or process with local condition inputs set equal to zero.  The network is then retrained or receives additional training on an extentd data set containing the general set of data, characterized by zero values for the local condition inputs, and data on specific local conditions, characterized by non-zero values for the local condition inputs.  The result is a trained neural network which functions as a general model when the inputs for the local conditions inputs are set equal to zero, and which functions as a model of some specific local condition when the local condition inputs match the encoding of the some local data set contained within the training data.  The neural network has an architecture and a number of neurons such that its functioning as the local model is partially dependent upon its functioning as the general model.  This trained neural network is combined with sensors, actuators, a control and communications computer and with a user interface to function as combine control system.

Abstract: Pseudo two-dimensional hidden Markov models (HMMs) are used to represent text elements, such as characters or words. Observation vectors for each text element are based on pixel maps obtained by optical scanning. A character is represented by a pseudo two-dimensional HMM having a number of superstates, with each superstate having at least one state. Text elements are compared with such models by using the Viterbi algorithm, first in connection with the states in each superstate, then the superstates themselves, to calculate the probability that a particular model represents the text element. Parameters for the models are generated by training routines. Probabilities can be adjusted to compensate for changes in scale, translations, slant, and rotation.      An embodiment is also disclosed for identifying keywords in a body of text. A first pseudo two-dimensional HMM is created for the words that may appear in the text. Each word in the text is compared with both models, again using the Viterbi algorithm, to calculate probabilities that the model represents the subject word. If the probability for the keyword is greater than that for the extraneous words, the subject word is identified as being the keyword. Preprocessing steps for reducing the number of words to be compared can be added.
