    摘要: Systems and methods for a self-regulating power supply for MEMS thermal actuators to achieve maximum actuator displacement while preventing over powering. The present invention includes a power supply configured to regulate electrical input power to a MEMS thermal actuator in order to provide the maximum possible electrical input power. Accordingly, the present invention provides a maximum actuator displacement while preventing device failure from over powering. The present invention utilizes resistivity versus temperature properties for silicon or the like to provide a self-regulating power supply that can be utilized to power a variety of MEMS components without requiring custom actuator control circuits for each type of component.

    摘要: A loop unrolling trasformation specified by loop unrolling factors UF[1], . . . , UF[k] is performed on a perfect nest of k multiple loops to produce an unrolled loop representation as follows. Moving from the outermost loop to the innermost loop of the nest, the unroll factor UF[j] of the current loop is examined. First, the separate unrolled loop body is expanded by the specified unroll factor UF[j]. Second, the loop header for the current loop is adjusted so that if the loop's iteration count, COUNT[j], is known to be less than or equal to the unroll factor, UP[j], then the loop header is simply an assignment of the index variable to the lower-bound expression; otherwise, the loop header is adjusted so that the unrolled loop's iteration count equals .left brkt-bot.COUNT[J]/UF[J].right brkt-bot. a rounded down truncation of the division. Third, a remainder loop nest is generated, if needed. The size of the generated code when unrolling multiple nested loops is substantially reduced. The proportion of the object code comprising lower execution frequency remainder loops is also substantially reduced. The compile-time of unrolled multiple nested loops is also substantially reduced.

    摘要: A system creates a desired current level within a traffic signal. A power supply unit receives an external power signal and transforms the power signal to a lamp current. A pulse generator monitors the value of the lamp current and automatically adjust the power usage of the current sink circuit to maintained a predefined current amplitude. A current pulser generates square current pulses at a frequency based at least in part on the frequency of the lamp current. A current sink superimposes the rectangular current pulse onto the lamp current and outputs a combined power signal to the alternating current power line.
