Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 11/00

US Classification:

714 24, 714 22

Abstract:

A Flash-based memory system comprises a plurality of Flash memory devices, a Flash controller communicating independently with each Flash memory device to perform memory operations, a power circuit providing power the Flash memory devices, and a CPU configured to perform a controlled powering down procedure upon detecting a power failure. In some embodiments, the Flash-based memory system includes a backup power source having a charge storage device and charging circuitry, the CPU configured to perform one or more test procedures on the charge storage device to provide an indication of a charge storage capacity of the charge storage device. A plurality of Flash-based memory systems may be mounted on a Flash-based memory card, and multiple such Flash-based memory cards may be combined into a Flash-based memory module. A number of Flash-based memory modules may then be removably mounted in a rack-mountable housing to form unitary Flash-based memory unit.

US Classification:

307 52, 327552, 327559

Abstract:

An active low-pass current filter apparatus and method reduces conducted emissions above a predefined cutoff frequency at high power levels. The apparatus and method use a bidirectional DC-DC converter to minimize current fluctuations on a power lead that may result in conducted emissions above the predefined cutoff frequency. The bidirectional DC-DC converter absorbs current from the power lead and feeds current to the load lead as needed to compensate for the current fluctuations on the power lead. Power to the DC-DC converter is provided by a separate auxiliary power source. A monitoring circuit compares the voltage level of the auxiliary power source to a reference voltage and compensates for variations in the voltage level of the auxiliary power source without interfering with the suppression of the conducted emissions.

International Classification:

G01R 21/06
G01R 31/40
G05B 15/02
H02J 13/00

Abstract:

A method, computer program product, and system for emulating a constant power (CP) electronic load (e-load) from a constant current (CC) e-load are disclosed. Testing metrics may be obtained for a power source to be tested, including one or more power thresholds. Further, an initial current level for a CC e-load may be obtained. The power-draw of the CC e-load connected to the power source may be determined. The determined power-draw may be compared to at least one of the one or more of the power thresholds. In response to the power-draw not satisfying the at least one power threshold, the current level of the CC e-load may be adjusted based on the power-draw and the at least one power threshold.
