  • Patent number: 6178014
    Abstract: An arrangement for illuminating objects wherein a large number of objects are rapidly and continuously transported past one or more stations, each illuminated by a cylindrical, integrating Lambertian reflecting/diffusing cavity having one or more like light sources therein so as to generate and project a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating optical guide means to couple said illumination beam to the face of the objects at said station and to couple the reflected image of the object back to the cavity.

  • Patent number: 6032231
    Abstract: A method and system for arranging and operating a multiprocessor computer server system having "split-transaction bus" architecture, including bus modules operating with an address phase and a cycle phase. The bus modules are arranged for access by a prescribed resource stage to facilitate "RETRY" operations. The method includes providing a Cache Tag and Address Compare, arranging the system so that a first bus module stores the address for the Resource stage in the Cycle Tag; and comparing subsequent address bus cycles to the contents of the Cache Tag so that, given a "match", a "RETRY" direction is responsively sent to any other bus module that requests access. The system provides components supporting the above method steps.

  • Patent number: 5991853
    Abstract: A "bit-sliced" construction of our cache module dictates dual TAG RAM structures and dual invalidation queues, yielding enhanced performance. By putting half the TAG array in each of two cache arrays, and allowing each to handle only one-half of the possible address values, processor operations and invalidation operations can be "overlapped", and even operate simultaneously.

  • Patent number: 5986427
    Abstract: A circuit for controlling a servomotor while minimizing a steady-state velocity error being associated with the servomotor. A velocity transducer is coupled to the servomotor to provide a first signal representing an angular velocity of a servomotor shaft. A comparator receives as input the first signal and a second signal representing a desired angular velocity of the servomotor shaft. The comparator produces a comparator output signal representing the steady-state velocity error as defined by a difference between the angular velocity of a servomotor shaft and the desired angular velocity of the servomotor shaft. Means are provided for deriving a value of a current flowing through the servomotor and for producing a third signal representing that current. The third signal represents a frictional torque applied to the servomotor shaft. An adder receives as input the comparator output signal and the third signal.
