摘要： The perforation of tipping paper on a high-speed perforation line is monitored and controlled by an electro-optic detection and data processing system which produces a signal related in value to an expected pressure drop through the paper based on calculations relating the inverse square of average perforation area to pressure drop. In one embodiment, a strobe light and camera are arranged on opposite sides of the tipping paper strip and provide an image signal to a vision processor. In another embodiment, a CCD line sensor located across the width of the strip is scanned to provide a signal related to a profile of light transmitted through the tipping paper.

摘要： A station optically inspects banded cigarette paper by directing an elongated beam of white light laterally across a web of the cigarette paper. The elongated beam impinges on the surface of the cigarette paper and forms reflections. A plurality of line scan camera containing linear CCD arrays receive the reflections and generate output signals. One or more processing units process the output signals to generate data indicative of the spacing between bands, the width of the bands, and the contrast of the bands. These calculations can be periodically transferred to a separate computer workstation over a network. The workstation generates statistical reports on the basis of the calculations, such as the band width, band spacing and band contrast as a function of lane number, and as a function of time. The statistical reports provide a convenient way of quickly detecting irregularities in application of the bands. According to exemplary embodiments, the inspection station is designed for installation in a cigarette paper manufacturing system.

摘要： A colorimeter provides compensation for changes in the color signature of an object due to lamp aging. A current measuring circuit measures current to the lamp during an initial training of the colorimeter and stores a value I.sub.T indicative of the lamp current at training. When an object is scanned by the colorimeter, lamp current is again sensed and assigned a value I.sub.S. Comparison between a sensed color signature and a stored color signature then occurs. Compensation is accomplished by modifying one of the two signatures by a ratio including I.sub.S and I.sub.T.

摘要： An enclosure sensing apparatus is provided which monitors the movement of a key structure relative to a housing structure. The purpose of the device is to determine that a moveable object has moved into an appropriate position relative to a stationary object. First, second and third magnetically sensitive devices are provided within a housing structure. First and second magnets are attached to a key structure that is moveable relative to the housing structure and a third magnet is provided within the housing structure to advantageously affect the operation of the second magnetically sensitive device. Several positions of the key structure can be specifically identified as the key structure passes through a path provided within the housing structure. In addition, a latching mechanism is provided to lock the relative position of the key structure and the housing structure when the key structure has reached a preselect position relative to the housing structure.

摘要： A monitoring device is provided for use in association with a limit switch or similar mechanically actuated device in order to permit its end of life to be predicted. The system uses nonvolatile random access memory to store a count which represents the number of occurrences of one of two alternative events. The first event is the occurrence of a number of switch actuations and the second event is the lapse of a predetermined period of time. When either of these two events occurs, a microprocessor increments a count in the nonvolatile memory unit and clears both the clock and the volatile memory parameter. When the number stored in the nonvolatile memory represents a number of actuations estimated to be appropriately equal to the total life of the switch, this condition can be signaled to a sensor bus by a communication circuit. Alternatively, a light emitting diode can be alternately energized and de-energized to represent the number of actuations having exceeded the predicted end of life total.

摘要： A colorimeter provides compensation for changes in the color signature of an object due to lamp aging, stand off distance and view angle changes. The colorimeter senses and stores values indicative of a sample object. In use, the colorimeter senses and creates values indicative of an object. The colorimeter includes a processor which then creates an average ratio wherein the stored values and corresponding sensed values are placed in a ratio, all of the ratios are then summed, and the total is divided by the number of values. Finally, the processor compares the sensed values with corresponding stored values, wherein one of the two values is adjusted by the average ratio.
