Abstract: A device for encouraging and guiding a spirometer user includes a housing, a main valve, a visual assembly, and a sound making assembly. The housing has a guiding channel, a first outlet channel, a second outlet channel, and an inlet channel. The main valve is disposed in a housing communicating with the guiding channel, the first outlet channel, the second outlet channel or the inlet channel and configured to regulate or control fluid flowing paths. The visual assembly includes a check valve in the second outlet channel, and at least one movable member. The sound making assembly includes a check valve and a sound maker. So, it can generate the visual and sound encouraging effects for learning how to use a spirometer correctly.

Abstract: A code disk is adapted to an optical absolute rotary encoder. The code disk is divided into a plurality of columns, with the plurality of columns disposed in a circumferential direction around a center position and respectively extending in a plurality of radial directions. The code disk comprises a plurality of disk sectors sequentially disposed in the circumferential direction around the center position, wherein each of the disk sectors comprises a plurality of code pieces, each of the code pieces comprises an encoded value, each of the encoded values comprises a plurality of bits adopting Manchester code, these bits are arranged in one of the radial directions, and the encoded values of two of the disk sectors are arranged as Gray code.

Abstract: An ultra-wide head-up display system and a display method thereof are provided. An ultra-wide image displayed by the ultra-wide head up display system is divided into independent head-up display images, an information type of each of the head-up display images is dynamically switched according to a usage status of a vehicle, each of the head-up display images is displayed in a corresponding outer frame, and each of the outer frames is formed by a display region not displaying an image.

Abstract: A projector device is provided. The projector device includes a projector unit, an optical beam splitting module and a first image forming element. The projector unit forms a beam projecting image. The horizontal projection width of the beam projecting image is smaller than the vertical projection width of the beam projecting image. The optical beam splitting module projects one or multiple projection sub-images according to the beam projecting image. The projection sub-images are projected to the first image forming element to form one or multiple projection images. Thus, the projector device obtains multiple projection images from a single image source, and the placement of the image forming elements in the projector unit may be adjusted to obtain the projection images with the best image ratios and the best resolutions. The projector device may be suitable for a head up display.
