Abstract: The present invention automates the process of selecting lids to be inserted over produce containers. In one embodiment, labels are affixed to the bottom container when the selected produce products have been loaded into the container. As the containers move along an assembly line, the label is read and the container directed to a specific lidding station where the desired lid is selected and placed over the container. Multiple lidding stations are provided such that the containers are automatically directed to the appropriate lidding station so that the selected lid may be placed on the container. Alternatively, the system may simply track the movement of containers and count quantities of containers rather than rely on labels affixed to the container. In this manner, containers full of produce are directed to the appropriate lidding stations where lids are automatically selected and positioned over the container.

Abstract: A robotic containerization and palletizing system having a multiple-fingered end effector. The system includes a frame that defines one or more cells. Each cell has one gantry-type robot, which is mounted in a set of tracks on top of the frame. The robot is movable along two axes and has an arm to which the end effector is mounted. The end effector is designed to grasp trays, tubs, and similar items from a conveyor system running through the cell and load them in a cart or on a pallet. The items are gripped by two sets of fingers. One set of fingers may be mounted to a first plate and another set of fingers may be mounted to a carriage that moves in a horizontal direction, either toward or away from the first set of fingers. Each finger has a main shaft and a bent tip. The shafts are rotatable such that the tips can be moved underneath or out from under a load, depending upon whether a pick-up or drop-off operation is being performed.

Abstract: Disclosed is a motorized machine which includes an electrical system monitoring system which results in detecting arcing in the electrical distribution system of the machine and the ability to provide notification and protection for such arcing. The system functions to monitor the electrical distribution system of the machine to sense the frequencies of signals in the system using appropriate filtering. One type of filtering which may be used is based upon a heterodyning circuit which provides variable frequency filtering for filtering a signal representative of the current in at least one electrical circuit of the machine. The heterodyning circuit output is configured to produce a signal which may be logarithmically related to the filtered signal. If the output signal exceeds a predetermined limit (representative of noise) for a predetermined period (representative of a typical arc duration), the system generates an arc signal.

Abstract: A method of interactively determining at least one optimized design candidate using an optimizer, the optimizer having a generation algorithm and an objective function, the optimized design candidate satisfying a design problem definition, comprises generating design candidates based on the generation algorithm. The generated design candidates are added to a current set of design candidates to form a new set of design candidates. The design candidates are evaluated based on the objective function so that design candidates can be selected for inclusion in a preferred set of design candidates. The current state of the optimizer is presented to a designer for interactive examination and input is received from the designer for updating the current state of the optimizer. These steps are repeated until a stopping criterion is satisfied.

Abstract: A storage and retrieval system is provided for safely and efficiently storing reticles in a clean environment. An enclosed storage unit is provided for storing the reticles, and other items such as wafers and the like, in an environment which minimizes the amount of contaminants and is suitable for use in a semiconductor fabrication clean room. A retrieval unit is provided separate from the enclosed storage unit for accessing and staging the reticles before they enter and leave the storage unit for minimizing exposure of the storage unit. The storage unit includes a movable storage matrix having a plurality of bays for storing the reticles. The movable storage matrix is selectively moved or rotated by a drive mechanism that is located external to the storage unit so that the storage unit is substantially free of contaminant generating components.

Abstract: A method of handling an object using a robot end effector. The method includes providing a robot having an end effector supporting a pair of carriages, providing a pair of fingers for each carriage, moving the end effector over an object, grasping an object with the fingers, moving the object with the end effector to a container, and depositing the object by counter-rotating the pairs of fingers. One or both of the carriages is movable toward the other carriage to engage objects on a conveyor system with the fingers. The robot moves the end effector between the conveyor system and shipping containers for shipping the objects. Because the pairs of fingers counter-rotate, the friction forces between each finger and the tray is offset by the friction forces between the other finger in the pair and the tray. The improved handling method thereby maintains objects substantially in the desired stacking orientation within the shipping container. Preferably, an actuator is provided for each finger.

Abstract: The CD profile of a web of material being produced is monitored and controlled to update CD control settings on-line so that changes in the operation of a machine manufacturing the web can be corrected before significant profile deviations from a desired CD profile target result. Detected variances in the profile that satisfy a search criteria initiate searches for improved CD control settings. The CD control of the present application recognizes CD actuator mapping misalignments, determines improved CD control settings and applies the improved CD control settings to fine tune a CD controller and thereby improve upon or correct mapping misalignments. The CD control of the present application also recognizes non-smoothness of the setpoints of the CD actuators and controls the smoothness of the setpoints. Recognition and correction of either CD actuator mapping misalignments or CD actuator setpoint smoothness or both can be performed by the automated optimization of the present application.

Abstract: Diagnostic strips of the kind which are exposed to biological fluids such as blood or urine to detect or monitor medical conditions are cut sequentially from elongated cards by a reciprocating shear blade. The cards may be ones which exhibit defective areas that should not be included in the finished strips. Blade motion seats each newly cut strip on a movable strip carrier which abuts the blade during the cutting operation. The carrier then travels a nondefective strip to a pickup location where it is precisely positioned and picked off of the carrier for emplacement in a housing. A strip with a defective area is carried further to a discharge location where it is released into a waste receptacle. This enables more economical manufacture of diagnostic strips by efficiently making use of nondefective areas of cards that have defective areas.

Abstract: A method and apparatus for improving communication throughout a network is disclosed. The network includes a module capable of transmitting messages in response to a change of state. Bit errors transmitted within network are detected and a detected bit error rate is calculated. A residual, i.e., undetected, error probability is determined in response to the detected bit error rate. Corrective action towards reducing the effects of the residual errors is taken, e.g., retransmission of messages, in response to the residual error probability exceeding a predetermined threshold.

Abstract: A contact gauge for measuring a contoured surface on work piece is presented having a matching contoured profile and multiple sensors inserted in a gauge body. The gauge body uses bores filled with spherical balls. At least one ball from each bore contacts the contoured surface, which causes displacement of the ball. The displacement is transferred to and recorded by the sensor. The layout of the gauge permits multiple sensors to be mounted in a compact gauge housing and the gauge housing, in turn, may connected to a robotic arm for rapid and repeated use as an automated measurement apparatus for a component assembly line.

Abstract: A method of multi-topology optimization is used in AMS circuit design to address the problem of selecting a topology while sizing the topology. First, design schematics are manually or automatically selected from a database of known topologies. Additional topologies can be designed as well. For each candidate design there is associated a topology and a set of parameters for that topology. Analogously to the step of automatic sizing for a single topology, multi-topology optimization comprises optimizing over the entire population of design simultaneously while not requiring that all topologies are fully optimized. The multi-topology optimization step is repeated until one or more stopping criteria are satisfied. The sized schematic is then passed onto placement, routing, extraction and verification.
