Abstract: Embodiments of the present invention provide an air dryer for an ion mobility spectrometer, comprising a heating element used to heat a thermal conduction device, thereby heating the desiccant. Embodiments of the present invention further provide a regeneration method, by which the operation mode of the ion mobility spectrometer may be switched, so that during a non-working time of the ion mobility spectrometer, the desiccant is heated and thereby regenerated. With the present invention, the desiccant is avoided from being regularly replaced, thereby improving the performance and increasing the service life of the dryer. Regeneration of the desiccant is performed by making full use of the non-working time of the ion mobility spectrometer without affecting normal operation of instrument.

Abstract: Devices and methods are described herein for providing foveated image projection. In general, at least one source of laser light is used to generate a laser beam, and scanning mirror(s) that reflect the laser beam into a pattern of scan lines. The source of light is controlled to selectively generate projected image pixels during a first portion of the pattern of scan lines, and to selectively generate depth mapping pulses during a second portion of the pattern of scan lines. The projected image pixels generate a projected image, while the depth mapping pulses are reflected from the surface, received, and used to generate a 3-dimensional point clouds that describe the measured surface depth at each point. Thus, during each scan of the pattern both a projected image and a surface depth map can be generated, with the surface depth map used to modify some portion of the projected pixels.
