  • Patent number: 11164396
    Abstract: A system, method, and computer-readable medium for servicing a system, comprising: displaying animated content relative to the system; determining a snapshot function has been initiated; sending a request to a user of an augmented reality device with a camera to move the augmented reality device relative to the system; capturing information about components in the system and a configuration of the system; generating a three dimensional (3D) model of the system based on the captured information; and displaying a composite view of the model or an overlay based on the model and animated content related to a component.
    Type: Grant

  • Publication number: 20020083237
    Abstract: The present invention incorporates a silicon based isolation device into a portable computer. An additional silicon based isolation device is also incorporated into a docking station for a personal computer. Either or both of the isolation components may be programmable. The invention also teaches a silicon based isolation device for use with a modem. Again, the silicon based isolation devices may be programmable. An embodiment of the invention teaches a circuit (or other means) to detect docking of the computer in a docking station.

  • Patent number: 5249277
    Abstract: A system and method for optimizing the performance of a computer memory system substitutes faster memory for a certain portion of the main memory. The substituted memory section automatically assumes a predesignated portion of the main memory and allows the main memory to become sequentially reorganized. Using this arrangement, for example, all the DOS applications that reside in the first 640 Kbytes of memory can be resident in the faster memory and the original main memory can then be used for other applications.
