Patent number: 5184336Abstract: A mechanical assembly for alternately producing displacement of a carriage with respect to a carriage track and rotation of a gear mounted on the carriage, in response to torque provided from a single drive motor including: a latching assembly, having a latched state and an unlatched state, operably associated with the carriage for preventing relative movement between the carriage and the track during the latched state; and a locking assembly, having a locked state and an unlocked state, operatively associated with the gear for preventing relative rotation of the gear during the locked state.Type: GrantFiled: December 13, 1991Date of Patent: February 2, 1993Assignee: Hewlett-Packard CompanyInventors: Mark E. Wanger, Jennifer L. Methlie, Donald J. Stavely, Thomas C. Oliver

Patent number: 5057758Abstract: Disclosed is an optical disk handling system, called an autochanger, having two control systems to provide the six motions necessary to move optical disk cartridges from storage holding cells to an optical drive. The system uses shaft encoders on two motors of the two control systems, and current or voltage feedback from the motors for all positioning, and for detecting the location of the mechanisms during, and at the end of, moves. The shaft encoders are used to position a mechanism close to the eventual move location, then motor current or voltage feedback is used to determine the opposition to the movement of the mechanism, which tells the control system whether the mechanism has reached its destination.Type: GrantFiled: March 20, 1989Date of Patent: October 15, 1991Assignee: Hewlett-Packard CompanyInventors: Thomas C. Oliver, Mark E. Wanger, Donald J. Stavely, Jennifer L. Methlie

Patent number: 5043962Abstract: A cartridge handling system including a cartridge engaging assembly for engaging an exposed end portion of a cartridge positioned in an aligned holding unit; a longitudinal displacement assembly for longitudinally displacing a cartridge engaged by the engaging assembly; a flipping assembly for invertingly rotating a cartridge engaged by the engaging assembly about a longitudinally extending flip axis; a lateral displacement assembly for laterally displacing a cartridge engaged by the engaging assembly; and a unitary, rotatable drive motor drivingly linked to the longitudinal displacement assembly, the flipping assembly, and the lateral displacement assembly for providing driving force thereto. The cartridge handling system is constructed and arranged such that neither sensors nor motors need be mounted on any moving system components.Type: GrantFiled: March 21, 1989Date of Patent: August 27, 1991Assignee: Hewlett-Packard CompanyInventors: Mark E. Wanger, Donald J. Stavely, Thomas C. Oliver, Jennifer L. Methlie

Patent number: 5040159Abstract: Disclosed is an optical disk handling system, called an autochanger, having two control systems to provide the six motions necessary to move optical disk cartridges from storage holding cells to an optical drive. The system uses shaft encoders on the motors of the two control systems, and current or votlage feedback from the motors, for all positioning, and for detecting the location of the mechanisms during and at the end of moves. The shaft encoders are used to position a mechanism close to the eventual move location, then motor current or voltage feedback is used to determine opposition to the movement to the mechanism, which informs the control system as to whether the mechanism has reached its destination. An important aspect of the invention is that the motor current or voltage feedback is used by one control system to provide five of the six motions.Type: GrantFiled: March 20, 1989Date of Patent: August 13, 1991Assignee: Hewlett-Packard CompanyInventors: Thomas C.
