  • Publication number: 20040032803
    Abstract: Methods for controlling the position of a plunge mechanism which is mounted to a cartridge engaging assembly are disclosed herein. In one method, the position of a plunge mechanism associated with a cartridge engaging assembly is regulated by 1) providing a reference mark on the plunge mechanism, 2) detecting a size of the reference mark on the plunge mechanism, and then 3) determining the position of the plunge mechanism based on the size of the detected reference mark. In another method, a plunge mechanism is moved to an extended position within a cartridge engaging assembly by 1) initiating movement of the plunge mechanism from a retracted toward an extended position in accordance with an open loop control schedule, and then 2) after moving the plunge mechanism for a predetermined distance, switching control of the movement of the plunge mechanism to a closed loop control schedule, and monitoring a detector which detects a reference mark provided on the plunge mechanism.

  • Publication number: 20040032802
    Abstract: Apparatus for controlling the position of a plunge mechanism which is mounted to a cartridge engaging assembly is disclosed herein. The apparatus may be embodied in a cartridge engaging assembly having a plunge mechanism that is moveable between a retracted position and an extended position. The plunge mechanism is provided with a reference mark that moves with the plunge mechanism. A detector is mounted to the cartridge engaging assembly, wherein the detector senses an image of the reference mark and produces an output signal related thereto. A control system is operatively associated with the detector and is responsive to the output signal produced thereby. The control system is also operatively associated with the plunge mechanism so that it regulates the position of the plunge mechanism based on the output signal.

  • Patent number: 6661748
    Abstract: Methods and apparatus for controlling the position of a plunge mechanism which is mounted to a cartridge engaging assembly are disclosed herein. In one embodiment, a cartridge engaging assembly includes a plunge mechanism which is mounted to the cartridge engaging assembly. The plunge mechanism is movable between a retracted position and an extended position. A reference mark is provided on the plunge mechanism so that the reference mark moves with the plunge mechanism. A detector is also mounted to the cartridge engaging assembly. As the plunge mechanism is extended, the detector detects the reference mark and produces an output signal which is related thereto. A control system is operatively associated with the detector and is responsive to the output signal produced thereby. The control system is also operatively associated with the plunge mechanism. As a result, the control system can regulate the position of the plunge mechanism based on the output signal produced by the detector.

  • Patent number: 6621654
    Abstract: An apparatus and method for retaining at least two different sizes of data cartridges in a storage magazine. A frame assembly defines a chamber in the storage magazine. The chamber is dimensioned to receive the largest of the two different sizes of data cartridges therein. A cartridge referencing member is mounted to the frame assembly and is resiliently displaceable within the chamber. The cartridge referencing member applies a biasing force to a data cartridge received therein to retain the received data cartridge in a registration position within the chamber to keep it from floating into an unknown position within the interior of the chamber.

  • Patent number: 6538752
    Abstract: The present invention is directed to a system and method which utilize a feedback loop arrangement to control the accurate positioning of components. The system and method may utilize the feedback loop to control a component engaging member operable to retrieve a component. The feedback loop may control the component engaging member by activating a drive subsystem operable to translate the component engaging member. Additionally, the feedback control loop may implemented by utilizing a signal source operable to emit a signal and a signal receiver operable to receive the signal emitted by the signal source. The signal source and signal receiver are fixedly attached to the device. Also, the feedback loop may involve a processor operable to control retrieval of a desired component utilizing at least in part the signal emitted by the signal source and received by the signal receiver.
