20100235012 | AUTOMATIC ADJUSTMENT OF THERMAL REQUIREMENT - Methods and apparatuses to automatically adjust a thermal requirement of a data processing system are described. One or more conditions associated with a data processing system are detected. A temperature requirement for the data processing system is determined based on the one or more conditions.

Detecting the one or more conditions associated with the data processing system may include determining a location of the data processing system based on a measured motion, a state of a peripheral device, a position of one portion of the data processing system (e.g., a lid) relative another portion of the data processing system (e.g., a bottom portion), a type of application operating on the data processing system, or any combination thereof. | 09-16-2010 |
20110301777 | ADJUSTING THE THERMAL BEHAVIOR OF A COMPUTING SYSTEM USING INDIRECT INFORMATION ABOUT AMBIENT TEMPERATURE - A computing system has a thermal manager that changes a power consuming activity limit in the device based on an estimate of temperature of a target location in the system. There are several temperature sensors that are not at the target location. An estimator computes the target location temperature estimate using a thermal model and, as input to the thermal model, data from the sensors. The thermal model produces different estimates of the target location temperature at different ambient temperatures but without computing or measuring the ambient temperatures. Other embodiments are also described and claimed. | 12-08-2011 |

20140365793 | THERMAL MANAGEMENT OF AN INTEGRATED CIRCUIT - Methods for thermal management of an integrated circuit are disclosed. In particular, a dual control loop, having a first control loop and a second control loop, is used to maintain the temperature of an integrated circuit at a first temperature and a second temperature, respectively. In order to prevent the integrated circuit from overheating during periods of rapid temperature increase, the second control loop may be configured to control temperature at the second temperature below the specification limit of the integrated circuit by reducing power to the integrated circuit. The second control loop samples and maintains temperature of the integrated circuit at time intervals relatively faster than that of the first control loop. However, the second control loop is configured to release control to the first control loop when the temperature of the integrated circuit is reduced. The first control loop may then control power to the integrated circuit. | 12-11-2014 |
