    摘要: An interactive energy effect system that includes one or more sensors configured to generate a signal indicative of a position of a user-associated object in the system. The interactive energy effect system also includes a system controller that receives the signal and generates a first and second set of instructions based on the signal. The system controller transmits the first instructions to an energy emission system to cause the energy emission system to reposition and activate an energy emitter. The system controller transmits the second instructions to a multi-layer display system to cause the multi-layer display system to move towards or away from the user-associated object.

    摘要: A system includes two stage HVAC equipment and processing circuitry configured to receive a call for conditioning and, in response to the call for conditioning, execute a recovery mode algorithm. The recovery mode algorithm is configured to determine an elapsed time between the call for conditioning and an ending of a recent cycle and compare the elapsed time to a threshold time period. The recovery mode algorithm is also configured to, in response to the elapsed time being below the threshold time period, determine a first stage up time based on a first function corresponding to the elapsed time being below the threshold time period. The recovery mode algorithm is also configured to, in response to the elapsed time meeting or exceeding the threshold time period, determine a second stage up time based on a second function corresponding to the elapsed time meeting or exceeding the threshold time period.

    摘要: A pre-patient collimator for a CT imaging system is provided. The pre-patient collimator includes a collimator housing including a plurality of walls, wherein the plurality of walls includes a first wall configured to face an X-ray source when the pre-patient collimator is coupled to the CT imaging system and a second wall and a third wall flanking the first wall. The pre-patient collimator also includes a bowtie filter assembly disposed within the collimator housing and including a bowtie filter. The pre-patient collimator further includes an adjustment mechanism configured to move the bowtie filter assembly in a lateral direction between the second wall and the third wall within the collimator housing.

    摘要: A method for correcting diffusion-weighted echo-planar imaging data (DW-EPI) includes obtaining a first reference scan with no diffusion gradients applied, a second reference scan with a diffusion gradient applied only along a frequency direction, a third reference scan with the diffusion gradient applied only along a phase direction, and a fourth reference scan with the diffusion gradient applied only along a slice direction acquired utilizing an MRI scanner, wherein the reference scans lack phase encoding. The method includes obtaining DW-EPI data acquired utilizing the MRI scanner, wherein the DW-EPI data includes phase errors due to oscillatory eddy currents causing time-varying B0 shift. The method includes generating a phase correction factor based on the reference scans and correcting the phase errors due to the oscillatory eddy currents in the DW-EPI data independent of diffusion gradient direction utilizing the phase correction factor to generate corrected DW-EPI data.

    摘要: This disclosure is directed to enhancing PLL performance via gain calibration and duty cycle calibration. It may be desirable to perform loop gain and duty cycle calibration simultaneously. However, doing so may result in prohibitive complexity and/or area/power penalty. To enable loop gain calibration and duty cycle calibration simultaneously, the duty cycle error and the gain error may be detected in the time domain, which may enable duty cycle calibration and loop gain calibration circuitries to share a phase detector. Detecting the duty cycle error and the loop gain error in the time domain may be accomplished by implementing an analog or digital PLL system, wherein the loop gain of the PLL system is a function of the input phase offset time.
