20090089604 | APPARATUS, SYSTEM, AND METHOD FOR EVENT, TIME, AND FAILURE STATE RECORDING MECHANISM IN A POWER SUPPLY - An apparatus, system, and method are disclosed for event, time, and failure state recording in a power supply. Disclosed is a power supply that receives AC voltage as an input and provides regulated DC voltage as an output; a microcontroller integrated into the power supply that regulates output voltage and monitors, records, and reports operating conditions of the power supply; and a non-volatile solid-state storage that can be repeatedly read from, written to, and erased by the microcontroller and integrated within the microcontroller such that only a single address is needed to access both the microcontroller and the solid-state storage, the solid-state storage configured to store operating data received from the microcontroller, the operating data including the recorded operating conditions of the power supply. | 04-02-2009 |
20090167089 | APPARATUS, SYSTEM, AND METHOD FOR A HIGH EFFICIENCY REDUNDANT POWER SYSTEM - An apparatus, system, and method are disclosed for a high efficiency redundant power system. First and second power supplies are connected in parallel to power a load. Each power supply includes a primary stage and a regulator stage. Each primary stage regulates voltage on an internal bus that is input for each regulator stage. Each regulator stage regulates a regulated bus connected to the load. A power meter detects power provided to the load and determines if the provided power is below a predefined power threshold. A regulator control module shuts down the regulator stage of the first power supply after the provided power falls below the predefined power threshold so the second power supply powers the load and the primary stage of the first power supply remains operational. A recovery module starts up the regulator stage of the first power supply after failure of the second power supply. | 07-02-2009 |
20090167228 | APPARATUS, SYSTEM, AND METHOD FOR CONTROLLING SPEED OF A COOLING FAN - An apparatus, system, and method are disclosed for controlling fan speed. A power sensing module senses input voltage and current of a power supply. The power supply includes one or more stages and regulates at least one output bus. A power calculation module calculates input power from the input voltage and the input current. A temperature sensing module senses an ambient temperature and/or a temperature at a component cooled by a fan. A fan speed calculation module calculates a fan speed signal for the fan. The fan speed signal is a function of the input power calculated by the power calculation module and the sensed temperature sensed by the temperature sensing module for at least a portion of a fan speed range. A fan speed transmission module transmits the fan speed signal to the fan and adjusts a fan speed based on the fan speed signal. | 07-02-2009 |
20090174393 | APPARATUS, SYSTEM, AND METHOD DETERMINING VOLTAGE, CURRENT, AND POWER IN A SWITCHING REGULATOR - An apparatus, system, and method are disclosed for measuring voltage, current, and power in a power supply. The apparatus consists of a voltage measuring module which measures the peak voltage through an inductor in a switching power supply stage of the power supply for a portion of the switching period. A current measuring module measures the peak current in the switching power supply stage for a portion of the switching period. The measured currents and voltages are proportional to the voltage and current at a point in the power supply where a power measurement is desired. The voltage and current values are multiplied along with a constant to provide an accurate measure of the power at a point in the power supply. The constant generally includes a combination of a calibration constant, an RMS conversion factor, a voltage conversion factor, and a current conversion factor. | 07-09-2009 |
20100007370 | APPARATUS, SYSTEM, AND METHOD FOR ERROR DETECTION IN A STAND ALONE POWER SUPPLY - An apparatus for error checking in a power supply includes a power module that determines that the power supply is in a self-test condition. The self-test condition involves the power supply being connected to an input power source while it is disconnected from the electronic load that it normally services. A load module connects an internal test load to the power supply when the power supply is in self-test condition, and an error checking module performs error check operations on the power supply while it is connected to the test load. The apparatus also includes a notify module that actuates an indicator when the error checking module determines that there are one or more faults in the power supply. The apparatus may also include a log module for storing error messages and reports in non-volatile memory. | 01-14-2010 |

20130167330 | DEVICE FOR FASTENING A DETACHABLE COVER ON A BUTTON - The invention relates to a device for securing a detachable cover for trimming or decorating at least one part of a button, which has a front side, a back side and, on its periphery, an edge side, said button being arranged on a base, e.g. a shirt. The cover has a front side and a back side and at least one wall side enclosing the edge side of the button, wholly or partially, said wall side has diameters of different lengths between its opposing inner sides or on the front side/back side of the cover, the longer diameter of which, at least two opposing points, is longer than the diameter of the button, wherein, when a pressure is applied radially from the outside towards the periphery of the cover at the points, the enclosing wall side and/or the cover is deformed at the same time as at least a second point located on a shorter diameter, and the enclosing wall side can be folded outwards in a direction from the center of the cover to create space for enclosing the edge side, whereupon, when the pressure is released, at least part of the inner side springs back against the edge side to secure the cover. | 07-04-2013 |
