  • Publication number: 20250134363
    Abstract: An endoscope tracker that measures the endoscope's motion using a pair of trackballs and two video cameras is provided. The trackballs measure real-time changes in the scope's position and rotation during an endoscopic procedure. The cameras detect scale lines on the scope's surface to correct accumulated trackball measurement errors. A dual modality tracking method measures the motion of the endoscope's insertion tube in real time, including insertion length, rotation angle, and their velocities. Optical trackballs measure the endoscope insertion tube's motion, and cameras correct cumulative errors. A purely optical endoscope tracker that measures the endoscope's motion is also provided, using video cameras and software that processes the images obtained from the video cameras to determine how the endoscope moves over time.

  • Publication number: 20240099271
    Abstract: A system for identifying irregularities in behaviors of a non-human animal, the system comprising a processing circuitry configured to: provide a behavioral baseline including first information on regular behaviors of the non-human animal over a given period of time when no irregularities occur; obtain data on a series of consecutively identified behaviors of the non-human animal identified over a second period of time; perform an action upon the data not complying with the behavioral baseline, thereby indicating an irregularity in the non-human animal behavior.

  • Patent number: 11673553
    Abstract: The invention provides a system (10) for a motor vehicle (100) that receives drive demand information (161S) indicative of an amount of drive demanded of a powertrain (129) of the vehicle (100), and controls an amount of drive torque applied by the powertrain (129) to one or more road wheels (111, 112, 114, 115) in dependence on the drive demand information (116S). The system also receives gradient information (11GS) relating to the driving surface and vehicle speed information (Sv). The control system, in dependence on the gradient and speed information, automatically causes a braking system (12d) to apply brake force to one or more of the wheels (111, 112, 114, 115) to prevent vehicle rollback, and adjusts the amount of brake force applied in dependence on the drive demand information (161S) to cause the amount of brake force applied to increase progressively as the amount of drive demand decreases.

  • Patent number: 11531485
    Abstract: A throttling engine throttles access to a high latency hybrid memory. A request is received for partition mapping of a virtual address for an R/W memory page. An entry is added to a partition page table that maps a virtual address to a physical address and comprises access information that is R/W. A throttled flag is set in an entry of a partition page extension table. The throttle entry corresponds to the entry. The access information is saved in an original access part of the partition page extension table, and the access information is replaced with an R value. Upon application fault receipt, a throttling test is performed on an address of the application fault. If the throttling test is false, the fault is passed through to an operating system fault handler and the throttling fault stage is ended, otherwise, a delay is implemented for slowing access to the memory.

  • Patent number: 11281483
    Abstract: Within a hashed page table maintained by a hypervisor, a special host real address configured to access a hardware device using access data intended to be invalidated is identified as part of a firmware assisted dump process for a virtual machine executing on the hypervisor. The special host real address is translated to a corresponding special guest real address. Within the hashed page table, the special host real address is replaced with the corresponding special guest real address, and the corresponding special guest real address is marked as invalid and requiring special handling. Subsequent to the replacing, the special host real address is invalidated. The special guest real address and translated address information are provided to the virtual machine subsequent to the invalidating, the translated address information comprising a set of host real addresses translated to corresponding guest real addresses.

  • Patent number: 11249804
    Abstract: A computer-implemented method and system for affinity based optimization of persistent memory volumes. Responsive to receiving a request for a parent virtual PMEM device, a total memory capacity is apportioned amongst virtual persistent memory (PMEM) resources and physical memory resources. In accordance with a target affinity characteristic, a set of virtual central processor unit (CPU) sockets are assigned. Each virtual CPU socket is configured based on at least one physical central processor unit (CPU) core in conjunction with a subset of the virtual PMEM and physical memory resources. Child virtual PMEM devices are created for respective ones of the virtual CPU sockets, each of the child virtual PMEM devices being dedicated to the parent virtual PMEM device.
