Abstract: A system for imaging an object comprising a surface for receiving the object to be imaged and an imaging device. The imaging device comprises a housing and a fixed focusing optical device mounted to the housing, whereby the fixed focusing optics comprises a lens for focusing light reflected from the object. A plurality of independent linear imaging sensors are positioned in the housing at different distances from the fixed focusing lens so that a face of each of the plurality of independent linear imaging sensors is aligned parallel to the surface. A processor is coupled to the plurality of independent linear imaging sensors for receiving an output signal from each of the plurality of independent linear imaging sensors representative of the reflected light. The lens defines a plane parallel to the surface, and the plurality of independent linear imaging sensors are adapted to receive reflected light from the object.

Abstract: An apparatus for measuring the weight of items on a conveyor includes a scale that generates a first signal corresponding to the weight of the items. A movable platform transports the items to the scale and generates a second signal corresponding to position of the items in relation to the scale. A dimensioner examines the items and generates a third signal representative of whether the items are singulated or nonsingulated. A processor receives the second and third signals and determines whether to associate the first signal with information stored in memory about a particular item based upon whether the particular item is singulated or nonsingulated.

Abstract: A method for processing scanned code data, including a plurality of strings, to determine whether the scanned code data is part of a valid code begins by examining a first string of a first scanned code data. A cluster is opened with the first string if the first string contains a start pattern. At least one valid middle portion of the first string is identified and a transition position count associated with the at least one valid middle portion is stored. A second scanned code data is searched for a second string matching at least part of the first string in the cluster. If a match is found, then the second string is added to the end of the cluster. The cluster is closed upon detection of a stop pattern and is then decoded.

Abstract: A scanner can read machine-readable code on an object. A scanner has a scanning device, a data device, and a registration device. The scanning device can repetitively scan the code and provide a scan signal repetitively corresponding to at least fragments of the code. The data device is coupled to the scanning device and responds to its scan signal for repetitively storing it. The registration device is coupled to the data device for reconstructing the code from at least two of the fragments of the code by relatively shifting the code fragments until they are in registration.

Abstract: A data processing system is disclosed in which a plurality of central processing units have access to all the system resources, i.e., have a peer relationship. During initialization of the data processing system, all the system resources are allocated to the individual central processing units according to a preselected distribution procedure, the identification of available resources thereafter being stored in the files of the individual central processing units. During the operation of the data processing system, the resources can be reallocated by a predetermined procedure. The central processing units entering such a relationship are required to include apparatus and/or software procedures that prevent access to system resources not assigned thereto. A mail box procedure, using locations in the main memory unit permit communication between the central processing units and are used in the dynamic allocation of resources.

Abstract: In a data processing system having a plurality of non-homogeneous central processing units, apparatus is disclosed that permits a central processing unit not having mechanisms for protection of the allocation of resources to be coupled to the data processing system while preserving a peer relationship among the central processing units. The protection apparatus is interposed between the coupled central processing unit and the system bus and reviews each access to data processing system resources to insure that the accessed system resource is available to the associated data processing system. In addition, the apparatus permits initialization procedures without interprocessor conflict, provides status information from the coupled central processing unit to a requesting central processing unit and permits selected control signals to be applied to the coupled central processing unit.
