  • Patent number: 11941298
    Abstract: A host system initiates an abort of a command that has been placed into a submission queue (SQ) of the host system. The host system identifies at least one of a first outcome and a second outcome. When the first outcome indicates that the command is not completed and the second outcome indicates that the SQ entry has been fetched from the SQ, the host system sends an abort request to a storage device, and issues a cleanup request to direct the host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry based on at least one of the first outcome and the second outcome.

  • Publication number: 20240074826
    Abstract: A surgical robot including at least one contact module, a control connection module, at least one first robotic arm, and at least one grip control device. A first transmission member of the control connection module drives the control module through a first transmission connecting member. A first shaft member of the first robotic arm is connected with the first transmission member while the grip control device is connected with the first robotic arm by a transmission interface. A force sensing member of the first robotic arm detects a first reaction force from the contact module so that the first robotic arm sends a feedback control signal to the grip control device to control a grip driving member to generate a force feedback for allowing a grip portion to move. Thereby, users can feel movement of the grip portion caused by the force feedback to avoid accidental iatrogenic injuries.
