  • Publication number: 20190209251
    Abstract: A tele-operated system includes a platform, a manipulator supported by the platform, a support structure supporting the platform, and a processor. In a platform movement mode the processor is configured to sense a manual movement of a link of the manipulator relative to the platform that moves the link from a first to a second positional relationship relative to the platform wherein a difference between the first and second positional relationships includes a displacement having components in first, second, and third directions that are perpendicular to one another, calculate, in response to the sensed manual movement, a command for the support structure that causes the link to move in the first direction so as to reduce the displacement in the first direction and does not change the displacement in the second direction, and transmit the command to the support structure so as to move the platform and the manipulator.

  • Publication number: 20190159857
    Abstract: A cart for supporting one or more instruments during a computer-assisted remote procedure can comprise a base; a steering interface having a portion configured to be grasped by a user; a sensor mechanism configured to detect a force applied to the steering interface by a user; and a switch operable between an engaged position and a disengaged position. The cart may further include a drive system comprising a control module operably coupled to receive an input from the sensor mechanism in response to the force applied to the steering interface and, on the condition that the switch is in the engaged position, to output a movement command based on the received input from the sensor mechanism. A driven wheel mounted to the base of the cart may be configured to impart motion to the cart in response to the movement command.

  • Publication number: 20190159856
    Abstract: A cart for supporting one or more instruments for a computer-assisted, remote procedure can include a base and a support structure extending from the base and adjustable to different configurations, the support structure being configured to support one or more instruments to perform a remote procedure. The cart can further include a steering interface configured to be grasped by a user and a sensor mechanism configured to detect a force applied to the steering interface. The cart also can include a drive system comprising a control module operably coupled to receive an input from the sensor mechanism in response to the force applied to the steering interface and information about a configuration of the support structure, the control module operably coupled to output a movement command based on the received input from the sensor mechanism and the information about the configuration of the support structure.

  • Patent number: 10285764
    Abstract: Robotic and/or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. One or more kinematic linkage sub-systems may include joints that are actively driven, passive, or a mix of both, and may employ a set-up mode in which one or more of the joints are actively driven in response to manual articulation of one or more other joints of the kinematic chain. In an exemplary embodiment, the actively driven joints will move a platform structure that supports multiple manipulators in response to movement of one of the manipulators, facilitating and expediting the arrangement of the overall system by moving those multiple manipulators as a unit into alignment with the workspace. Manual independent positioning of the manipulator can be provided through passive set-up joint systems supporting the manipulators relative to the platform.

  • Patent number: 6252740
    Abstract: A cartridge for a magnetic disk drive has a rigid shell and a flexible door which covers an opening through which read/write heads engage the recording medium. The flexible door is guided outside of the shell to an open position as the cartridge is inserted into the drive. A projection on a flexible arm in the drive catches a hole in the flexible door to open it as the cartridge is inserted into the drive. The door along the outside of the cartridge conserves space so that the recording medium can be large for a given form factor drive.

  • Patent number: 5887176
    Abstract: The invention encompasses a system that utilizes radio frequency circuitry in combination with microprocessor devices and specially designed software to provide an improved structure and operation for the monitoring, protection and control of inventory assets. Generally, the system is embodied in a system controller unit, one or more interrogator devices and multiple transponder units. The system controller unit may be a personal computer (PC) based device for effecting the control and monitoring of the system's operation. In addition, the system controller unit serves as a data collection device and as an alarm device. The interrogator device(s) incorporate a transceiver controlled by microprocessor circuitry within the interrogator devices. The transponder units also include a radio transceiver and microprocessor circuitry. The transponder units are attached to a container or item to be monitored and protected.

  • Patent number: 5831795
    Abstract: A head loading mechanism for a removable cartridge disk drive comprises a support base fixedly mounted in the drive, and a moveable member movably attached to the support base via a pair of elongate flexures. The moveable member has a ramped surface adapted to engage a suspension arm at the distal end of an actuator. A read/write head is mounted on the suspension arm. The moveable member moves upon the flexures in tandem with the actuator as it moves toward and away from the edge of a disk inserted in the drive. The moveable member carries the suspension arm of the actuator to the edge of the disk, at which point the suspension arm can ride up and down the ramped surface of the moveable member in order to load the read/write head onto the surface of the disk and then subsequently to unload the read/write head from the disk.

  • Patent number: 5768059
    Abstract: In a magnetic disk drive heads are loaded and unloaded onto the magnetic disk by wings attached in close proximity to the magnetic heads. The wings ride on opposed profiles to separate the heads so that they can travel on either side of the disk and the heads are then brought together properly onto the disk. As the heads are withdrawn from the disk, they are separated by the opposed profiles and then the heads are parked on a cleaning pad.
