  • Patent number: 6854584
    Abstract: The invention is particularly useful for sorting, altering or maintaining the orientation items of differing sizes moved by a sorter. The endless loop's carriers include belts that both transport and sort the items. Followers clasp the belts about the lengthwise periphery of the carriers' slats and also engage lines, diverters, crossovers and receivers. When a follower is diverted toward a crossover, transverse motion is imparted to its corresponding carrier's belt. Routers can be incorporated into the sorter for enhancing the control of the orientation and sortation of items advanced by the endless loop's carriers.

  • Patent number: 6848675
    Abstract: The invention provides a hoist drive system for controlling the position of a hoist platform in a palletizer. In an embodiment of the invention, a hoist drive system comprises two electrical motors with dual output shafts. One motor may have an encoder for taking measurements relating to the rotation of the motor. A common shaft with a spring set safety brake ties the motors together. The two motors may be flux vector motors controlled with input from the encoder. The motors drive two gearboxes, thereby enabling vertical displacement of a hoist platform coupled to the drive system.

  • Patent number: 6851095
    Abstract: A technique to verify, evaluate, and estimate the performance of an integrated circuit is embodied in a computer software program that is executable by a computer system. The technique accurately estimates of the performance (e.g., transient delays) of an integrated circuit, and has fast execution times. The technique includes an incremental recharacterization feature where only portions of the design which have been changed or are new or different will need to be recharacterized during subsequent runs of the software. Portions of the design which are the same need not be recharacterized, and results for those portions from a previous run (stored in a database) are used. This saves execution time since the performance recharacterization or evaluation process is generally more time consuming than a database look up. The technique is applicable to small circuits having relatively few transistors, and especially well suited for integrated circuits having millions of transistors and components.

  • Patent number: 6847861
    Abstract: A carousel used in a restocking system is comprised of a drive track. A plurality of bins are arranged into rows, with the rows being driven by said drive track. A drive mechanism, e.g. an electric motor, drives the drive track. A sensor is provided to sense the position of the rows of bins. A processor is responsive to the sensor and data representative of a plurality of picks for more than one order for controlling the drive mechanism. By combining picks from different orders into a batch, the time spent driving the rows and time between picks is minimized. The carousel may be divided into a plurality of columns, each with its own drive track, drive mechanism, and sensor, to enable several rows to be brought into a pick position simultaneously.

  • Patent number: 6837663
    Abstract: In a loading and unloading station for semiconductor processing installations, the object of the present invention is to ensure charging proceeding from transporting containers under clean room conditions. These transporting containers themselves serve as magazines for disk-shaped objects and are open laterally. It should also be possible, optionally, to load and unload a greater quantity of such transporting containers, wherein the exchange of transporting containers must be effected under favorable ergonomic conditions. According to the invention, the transporting container for loading, unloading and reloading of disk-shaped objects is coupled in a stationary manner by the container cover with the closure by using an adhering engagement. The charging opening and the transporting container are opened simultaneously in that the container cover and the closure are moved down jointly into the semiconductor processing installation.

  • Patent number: 6839785
    Abstract: A communication interface involves a processor that communicates to expansion modules in order to read and write discrete input/output, analog input/output, intelligent module control, and expansion module status. The expansion modules can be application specific integrated circuits (ASIC), each having a state machine architecture that responds appropriately to the input/output expansion bus signals. The ASIC can include error detection using the first byte of messages from the controller. Thus, the ASIC detects when an erroneous message from the controller has been communicated and transmits a message to expansion modules that their output states not be changed in response to the message from the controller.
