摘要:
A machine vision image acquisition system is provided with a housing or enclosure that protects the acquisition system components from an industrial environment. The machine vision image acquisition system has a focusing mechanism that can be actuated externally to the housing. The focusing mechanism uses a gear drive to transmit externally actuated focus adjustments to the optical components of the acquisition system.

The invention provides, in some aspects, devices for image acquisition that use seals between concentrically disposed portions of an enclosure and an optics assembly in order to protect image acquisition components from the surrounding environment while providing adequate friction for both adjusting and locking focus. Such devices can include an image capture medium that is disposed within an enclosure and an optics assembly that is also disposed within that enclosure. The optics assembly, which includes at least a lens, can have a cylindrical outer diameter along at least a portion of its length that is received within the enclosure along a length that has a corresponding cylindrical inner diameter. A first seal is disposed between, and in contact with, the optics assembly and the enclosure. That seal permits rotation of the optics assembly for purposes of focusing the lens, while preventing contamination from the environment from entering into the enclosure.

The invention provides, in some aspects, devices for image acquisition that use seals (e.g., O-rings) between concentrically disposed portions of an enclosure and an optics assembly (or sub-assemblies thereof) in order to protect image acquisition components from the surrounding environment (and vice versa) while, at the same time, providing adequate friction for both adjusting and locking focus. Such devices include, in one aspect of the invention, an image capture medium (e.g., a CMOS sensor, CCD array, etc.) that is disposed within an enclosure and an optics assembly that is also disposed within that enclosure, rotatably. The optics assembly, which includes at least a lens, can have a cylindrical outer diameter along at least a portion of its length that is received within the enclosure along a length that has a corresponding cylindrical inner diameter. A first seal (e.g., an “O-ring”) is disposed between, and in contact with, the optics assembly and the enclosure, e.g., along these corresponding lengths. That seal permits rotation of the optics assembly for purposes of focusing the lens, while preventing (or reducing a risk of) contamination from the environment (e.g., water, chemicals, dirt, dust, etc.) from entering into the enclosure and vice versa.

A method and apparatus for sterilization of webs and products made therefrom using electron beams (ebeams) is provided. A controller is configured to modulate an ebeam to ensure that a non-continuously moving web is sterilized within a desired range of exposure. During sterilization in place operations, manifolds are configured to operate to ensure that sterilants do not enter an irradiation zone to prevent damage to ebeam emitters.

A process controller implements smart field device standards and other bus-based architecture standards so that communications and control among devices are performed so that the standard control operations are transparent to a user. The process controller allows attachment to a theoretically and substantially unlimited number and type of field devices including smart devices and conventional non-smart devices. Control and communication operations of the various numbers and types of devices are performed simultaneously and in parallel.

A computerized drop safe running control and security software on a central processing unit controlling (CPU) operating features on and access to the drop safe. A user hierarchy has different access policies for making different transactions into the safe. Vault door access is controlled by the CPU to allow user access according to enabled policies. Transactions into and out of the safe vaults, motovend tube dispenser, and currency recyclers are recorded by the amounts and the user making the transaction into a memory coupled to the CPU. This data is also reported to a point of sale control interface at another location using a modem or Ethernet connection. The CPU can also receive data and control inputs by the modem and Ethernet, permitting centralized accounting and vending control options. A back office at the store can also easily access the safe for data retrieval or control inputs into the CPU using an Ethernet local area network computer system.
