20130181059 | TESTING APPARATUS FOR PREVENTING FREEZING OF RELAYS IN ELECTRICAL COMPONENTS - Disclosed herein are embodiments of testing apparatus used to prevent freezing of relays in electrical components, particularly electrical components used in vehicles. One embodiment of a testing apparatus comprises a chamber with temperature control configured to control a temperature of an internal atmosphere of the chamber and a humidifier in fluid communication with the internal atmosphere of the chamber configured to supply humidified air to the internal atmosphere. A sealable opening in a wall of the chamber is configured to pass a wire harness from external the chamber to inside the chamber while maintaining a sealed environment within the chamber. The temperature control is configured to maintain a sub-zero temperature in the internal atmosphere while the humidifier maintains a saturated internal atmosphere. | 07-18-2013 |
20130181732 | METHODS OF PREVENTING FREEZING OF RELAYS IN ELECTRICAL COMPONENTS - Disclosed herein are methods of preventing freezing of relays in electrical components operated in specific atmospheric conditions. One such method described herein comprises monitoring a temperature of a relay with a thermocouple located on a contact of the relay while monitoring ambient temperature within the relay. Operation of the electrical component is simulated in a sub-zero temperature and high humidity condition. A freeze potential of the relay is determined by plotting a temperature cross-over curve, wherein both the ambient temperature and the contact temperature are plotted during the operation and cool down period. If the high freeze potential is determined, one or both of the relay and the electrical component are modified with a modification configured to decrease the high freeze potential. | 07-18-2013 |

20150178364 | METHOD AND SYSTEM FOR REPLICATING DATA IN A CLOUD STORAGE SYSTEM - A method for replicating data in a cloud storage system supporting multiple clients, wherein the cloud storage system comprises a plurality of object storing entities (A, B, C) for storing data objects, includes requesting, by a client, values and associated timestamps for a first data object from a first quorum of the object storing entities (A, B, C). The method further includes determining, by the client, a most recent value of the first data object based on the associated timestamps. The method additionally includes performing, by the client, a compare-and-swap procedure, so that the determined value and its corresponding timestamp for the first data object updates the first data object with a value with a newer timestamp and stores the first data object in a second quorum of the object storing entities (A, B, C). | 06-25-2015 |

20140245028 | SYSTEM AND METHOD FOR TEMPERATURE DRIVEN SELECTION OF VOLTAGE MODES IN A PORTABLE COMPUTING DEVICE - Various methods and systems for minimum supply voltage level selection in a portable computing device (“PCD”) are disclosed. It is an advantage of the various embodiments that PCD designers may close timing at a certain minimum supply voltage and operating temperature threshold that is higher than the lowest end of the main operating temperature range within which the PCD must function. By closing timing at the higher operating temperature threshold, relatively smaller components requiring relatively lower power consumption may be used in the PCD, thereby providing improved overall power consumption when the PCD is operating at operating temperatures above the threshold. To maintain functionality when operating temperatures fall below the threshold, the minimum supply voltage to the components is increased. The systems and methods sacrifice power consumption concerns below the operating temperature threshold in exchange for reduced form factors and improved power efficiencies in higher, more typical operating temperature conditions. | 08-28-2014 |

20130079946 | ON-CHIP THERMAL MANAGEMENT TECHNIQUES USING INTER-PROCESSOR TIME DEPENDENT POWER DENSITY DATA FOR INDENTIFICATION OF THERMAL AGGRESSORS - Various embodiments of methods and systems for controlling and/or managing thermal energy generation on a portable computing device are disclosed. Data discarded from one or more processing core registers may be monitored and analyzed to deduce individual workloads that have been processed by each of the cores over a unit of time. From the deduced workloads, the power consumed by each of the cores over the unit of time in order to process the workload can be calculated. Subsequently, a time dependent power density map can be created which reflects a historical and near real time power consumption for each core. Advantageously, because power consumption can be correlated to thermal energy generation, the TDPD map can be leveraged to identify thermal aggressors for targeted, fine grained application of thermal mitigation techniques. In some embodiments, workloads may be reallocated from the identified thermal aggressors to the identified underutilized processing components. | 03-28-2013 |

20100097101 | DISTRIBUTED SUPPLY CURRENT SWITCH CIRCUITS FOR ENABLING INDIVIDUAL POWER DOMAINS - An integrated circuit includes multiple power domains. Supply current switch circuits (SCSCs) are distributed across each power domain. When a signal is present on a control node within a SCSC, the SCSC couples a local supply bus of the power domain to a global supply bus. An enable signal path extends through the SCSCs so that an enable signal can be propagated down a chain of SCSCs from control node to control node, thereby turning the SCSCs on one by one. When the domain is to be powered up, a control circuit asserts an enable signal that propagates down a first chain of SCSCs. After a programmable amount of time, the control circuit asserts a second enable signal that propagates down a second chain. By spreading the turning on of SCSCs over time, large currents that would otherwise be associated with coupling the local and global buses together are avoided. | 04-22-2010 |
