A mirror assembly for a vehicle includes a mirror element having at least one substrate that has a forward surface and a rearward surface. The mirror element comprises at least one substantially reflective metallic layer sandwiched between a respective pair of substantially transparent non-metallic layers. Each of the substantially transparent non-metallic layers and the substantially reflective metallic layer have a selected refractive index and a selected physical thickness such that the reflective element is selectively spectrally tuned to substantially transmit at least one preselected spectral band of radiant energy therethrough while substantially reflecting other radiant energy. A radiant energy emitting element is disposed at or near the rearward surface of the at least one substrate. The radiant energy emitting element is configured to emit radiant energy with a peak intensity within the at least one preselected spectral band.

In a predetermined range from a nose portion toward a scroll finish side in a scroll casing of a centrifugal blower, a first clearance dimension on a side of a suction port between an outer periphery of a centrifugal fan and a side plate of the scroll casing is set smaller than a second clearance dimension on a side opposite to the suction port between the outer periphery of the centrifugal fan and the side plate of the scroll casing. In addition, in the vicinity of the nose portion, a first wall part of the scroll casing on the side of the suction port protrudes toward a scroll finish side, from a second wall part of the scroll casing on the side opposite to the suction port.

Critical needs for MRI patient instruction, testing, comfort, motion control, and speech communication are provided for better imaging which leads to more effective medical care. An MRI Digital Video Projection System is disclosed which provides better quality display to the patient to better inform, instruct, test, and comfort the patient plus the potential to stimulate the brain with microsecond onset times to better diagnose brain function. An MRI Motion Tracker and Patient Augmented Visual Feedback System enables monitoring patient body part motion, providing real time feedback to the patient and / or technician to substantially improve diagnostic yield of scanning sessions, particularly for children and mentally challenged individuals. An MR Forward Predictive Noise Canceling Microphone System removes the intense MRI acoustic noise improving patient communication, patient safety and enabling coding of speech output. These systems can be used individually but maximum benefit is from providing all three.
