| 20090119649 | STATIC ANALYSIS DEFECT DETECTION IN THE PRESENCE OF VIRTUAL FUNCTION CALLS - A computer-implemented error detection mechanism for detecting programming errors in a computer program. The computer-implemented error detection method described herein can make use of a Function Behaviour Knowledge Base (FBKB) to approximate how a virtual function changes state of the program execution for all methods that can be called at each specific invocation point. The FBKB is used to select what implementation of a virtual function should be called in order to give rise to a programming defect. By dropping implementations that do not lead to a programming defect, the set of possible object runtime types is reduced. If this set is empty by the end of the analysis, then a defect is not possible, otherwise the set of object runtime types will contain types that may cause a defect. | 05-07-2009 |

| 20090142858 | Power-Measured Pulses for Thermal Trimming - A circuit for trimming a thermally-trimmable resistor, measuring a temperature coefficient of resistance of the thermally-trimmable resistor, and annealing a thermally-trimmable resistor post-trimming, the circuit comprising: a thermally-isolated area on a substrate housing the thermally-trimmable resistor; heating circuitry for applying a signal to a heating resistor; and a constant-power module adapted to maintain power dissipated in the heating resistor substantially constant over a duration of the signal by varying at least one parameter of the signal as a result of a change in resistance of the heating resistor during the signal. | 06-04-2009 |
| 20090322356 | THERMAL PRE-SCANNING OF ELECTRIC CIRCUITS USING THERMALLY-TRIMMABLE RESISTORS - There is described a method to change the value of a thermally-trimmable resistor in a non-permanent way by raising the temperature of the thermally-trimmable resistor to a level that is somewhere between room temperature and trimming temperature. By doing this, the trimming range that is available via true thermal trimming may be explored without actually trimming the value of the resistor. This is possible when the thermal Iy-trimmable resistor, or a portion thereof, has an essentially non-zero temperature coefficient of resistance (TCR). | 12-31-2009 |
| 20100101077 | BIDIRECTIONAL THERMAL TRIMMING OF ELECTRICAL RESISTANCE - There are described various methods and circuits for trimming the parameter value of a thermally mutable electrical component in two directions. A sequence of heat pulses is selected as a function of thermal history using an adaptive trimming algorithm, where parameters of the sequence of heat pulses are based on a resulting impact of previous heating pulses. Direction of trimming, trimming increment, and remaining trimming distance can all be used to determine the parameters of succeeding heat pulses, wherein the parameters of the pulses can be, for example, amplitude, duration, and time interval between pulses. | 04-29-2010 |
| 20110220631 | METHOD OF STABILIZING THERMAL RESISTORS - There is described a method for stabilizing a post-trimming resistance of a thermally isolated electrical component made from a thermally mutable material, the method comprising: generating at least one heating pulse, the at least one heating pulse having an initial amplitude corresponding to a trimming temperature, a slope corresponding to a given cooling rate and a duration corresponding to a given cooling time; and applying the at least one heating pulse to one of the thermally isolated electrical component and a heating device in heat transfer communication with the thermally isolated electrical component, after a trimming process, in order to cause the electrical component to cool in accordance with the given cooling rate, the given cooling rate being slower than a passive cooling rate determined by the thermal isolation of the electrical component | 09-15-2011 |
