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
20110320060Methods and systems for measurement and control of process parameters - Systems and methods for monitoring various process parameters, primarily in connection with processes for the sterilization of particulate foods in a continuous thermal process, make use of application specific integrated circuits (ASIC) that provide process-related data for batch or continuous thermal treatment when the circuit is embedded in a particle subjected to such treatment. The preferred methods are described in connection with process design, and with at least near real-time process control using process data provided by such circuits.12-29-2011
20100198425PROGRAMMABLE THERMOSTAT - A programmable thermostat is disclosed having a continuously movable indexing mechanism, such as a rotatable wheel, that allows a user to scroll or cycle through sequential time intervals ranging over a complete week to view currently programmed time intervals and to select periods of time during the week that the user wishes to program or reprogram. Such a design allows a user to easily program different temperature settings during different time intervals during the week and allows the user to easily view the programmed settings.08-05-2010
20130173082METHOD AND APPARATUS FOR PROGRAMMABLE THERMAL SENSOR FOR AN INTEGRATED CIRCUIT - A programmable thermal sensor is implemented in an integrated circuit such as a microprocessor. The programmable thermal sensor monitors the temperature of the integrated circuit, and generates an output to indicate that the temperature of the integrated circuit has attained a pre-programmed threshold temperature. In a microprocessor implementation, the microprocessor contains a processor unit, an internal register, microprogram and clock circuitry. The microprogram writes programmable input values, corresponding to threshold temperatures, to the internal register. The programmable thermal sensor reads the programmable input values, and generates an interrupt when the temperature of the microprocessor reaches the threshold temperature. In addition to a programmable thermal sensor, the microprocessor contains a fail safe thermal sensor that halts operation of the microprocessor when the temperature attains a critical temperature.07-04-2013

20130158737UTILIZATION OF OVERVOLTAGE AND OVERCURRENT COMPENSATION TO EXTEND THE USABLE OPERATING RANGE OF ELECTRONIC DEVICES - A method induces augmented levels of heat dissipation by exploiting quiescent IC leakage currents to control the temperature in high power devices. A heat control and temperature monitoring system (HCTMS) utilizes a thermal sensor to sense the junction temperature of a component, which becomes self-heated due to the quiescent leakage current inherent to the component upon the application of power to the component. By increasing the voltage level of the power source, this quiescent self-heating property is augmented, which serves to accelerate the preheating of the device, until the temperature rises above the minimum specified operating temperature of the component. The method further includes reliably initializing the system by applying full system power and triggering a defined initialization sequence/procedure. Once the component is operational, the method includes maintaining the component's temperature above the minimum operating threshold via continued self-heating, continued augmentation of the applied DC voltage, or both, where required.06-20-2013
