During operation, the system obtains telemetry data comprising a set of raw signals gathered from sensors in the computer system during operation of the computer system, wherein the telemetry signals are gathered over a monitored time period. Next, for each raw signal in the set of raw signals, the system decomposes the raw signal into deterministic and stochastic components. The system then generates a corresponding set of synthesized signals based on the deterministic and stochastic components of the raw signals, wherein the synthesized signals are generated for a simulated time period, which is longer than the monitored time period. Finally, the system uses the set of synthesized signals to validate one or more performance metrics of the prognostic-surveillance mechanism.

  • Patent number: 10199824
    Abstract: In a particular illustrative embodiment of the present invention, an inter-island power transmission system is disclosed. An electronic box is placed on each end of a medium voltage three phase power cable running between two islands. The electronic box senses an open cable on the three phase cable and switches to direct current power transmission on the remaining two good cables. The direct current power is converted back to three phase power transmission on the receiving end of the direct current power.

  • Patent number: 10186181
    Abstract: A method for adjusting brightness includes detecting whether damage occurs on a light guide plate of the display device, determining a damage position and a damage extent of the light guide plate when the damage occurs on the light guide plate, and compensating for a change value of brightness generated due to the damage by adjusting the brightness of the display device corresponding to the damage position, according to a predetermined correspondence between damage extents and change values of brightness. The method for testing a display device includes applying a destructive operation to the display device to be tested, detecting a damage extent generated by the destructive operation and a change value of brightness correspondingly generated in a damage region, and creating and storing a correspondence between the damage extent and the change value of brightness.

  • Patent number: 10135234
    Abstract: A current flows between the drains of FETs, which function as a switch. A first constant current circuit causes a constant current to flow from the FET side of a resistor to the other side thereof. A first comparator outputs a high level voltage to the control section if the electric potential at the drain of the FET is higher than the electric potential at one end, on the first constant current circuit side, of the resistor. Furthermore, the first comparator outputs a low level voltage to the control section if the electric potential at the drain of the FET is lower than the electric potential at one end, on the first constant current circuit side, of the resistor. The control section turns the FETs off when the first comparator outputs the low level voltage. Furthermore, the control section changes the current that is caused to flow through the resistor by the first constant current circuit.

  • Patent number: 10041987
    Abstract: Disclosed are systems, devices and methods related to miniature probes that can be utilized for electrical and/or magnetic field strength measurements for areas that are smaller than an area of a radio-frequency (RF) module. In some embodiments, an electrical probe can be configured to include an unshielded inner conductor at an end of a coaxial assembly to allow an electrical field to induce differential-mode currents in the coaxial assembly. In some embodiments, a magnetic probe can be configured to include a loop connected to inner and outer conductors of a coaxial assembly to induce a common mode current by a change in magnetic field flux through the loop. In some implementations, such probes can be utilized to obtain near-field measurements to facilitate applications such as electromagnetic (EM) shielding designs.
