Abstract: A 2D image-guided surgical robot system for distal locking operations includes surgical image acquisition equipment, a robot arm, a robot end effector attached to the robot arm, and a remote operation workstation. To perform a distal locking operation, the position of the image acquisition device is adjusted to obtain a round outline of a lockhole in the image. A distortion correction is performed. The position of the target lockhole is assigned by a user through the GUI of the remote operation workstation, and the remote operation workstation calculates a robot motion quantity using image feedback control law and moves the robot accordingly. The “image-and-move” procedure is repeated several times until the drill guide is accurately aligned to the lockhole, then the distal locking operation is accomplished by first drilling a guide hole using a guide wire through the drill guide, and then screwing a locking screw through the guide hole.

Abstract: Techniques are provided for object store mirroring. Data within a storage tier of a node may be determined as being data to tier out to a primary object store based upon a property of the data. A first object is generated to comprise the data. A second object is generated to comprise the data. The first object is transmitted to the primary data store for storage in parallel with the second object being transmitted to a mirror object store for storage. Tiering of the data is designated as successful once acknowledgements are received from both the primary object that the first object was stored and the mirror object store that the second object was stored.

Abstract: A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In one example, the circuitry is configured to generate a null data packet (NDP), transmit at least a portion of the NDP to another wireless communication device via fewer than all of a plurality of sub-channels of a communication channel, and receive feedback from the another wireless communication device that is based on the another wireless communication processing the at least the portion of the NDP that is received via the fewer than all of the plurality of sub-channels of the communication channel. In one example, the generated NDP includes at least one signal field (SIG) field therein that includes information to specify a preamble puncturing option or the information is transmitted in a previous packet.

Abstract: A computer accesses a first symbolic expression for an output matrix as a function of an input matrix at a computing device comprising processing circuitry and memory. The computer computes a first Jacobian of the input matrix with respect to an input tangent space. The computer computes a second Jacobian of the output matrix with respect to the input matrix. The computer computes a third Jacobian of an output tangent space with respect to the input matrix. The computer applies symbolic matrix multiplication to the first Jacobian, the second Jacobian, and the third Jacobian to obtain a second symbolic expression for the output tangent space with respect to the input tangent space. The computer provides a representation of the second symbolic expression, the second symbolic expression representing a computed tangent-space Jacobian.
