  • Patent number: 10816919
    Abstract: According to an embodiment, a power source device includes a direct current power source, an alternating current power source, a bypass capacitor, and a power source control unit. The direct current power source outputs a direct current voltage. The alternating current power source outputs a superimposed voltage having an alternating current voltage superimposed on the direct current voltage. The bypass capacitor partially accumulates a charge of alternating current for prevention of flow of current into the direct current power source from the alternating current power source. The power source control unit switches control of the direct current voltage from constant current control to constant voltage control and causes a charge of the alternating current to be accumulated in the bypass capacitor in a short time period between a transfer period and a non-transfer period both related to image formation.

  • Patent number: 10540612
    Abstract: The disclosed embodiments relate to a system for validating a prognostic-surveillance mechanism, which detects anomalies that arise during operation of a computer system. 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: 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.
