Abstract: An image-type intubation-aiding device comprises a small-size image sensor and a light source module both placed into an endotracheal tube to help doctors with quick intubation. Light from light emission devices in the light source module passes through a transparent housing and is reflected by a target and then focused. The optical signal is converted into a digital or analog electric signal by the image sensor for displaying on a display device after processing. Doctors can thus be helped to quickly find the position of trachea, keep an appropriate distance from a patient for reducing the possibility of infection, and lower the medical treatment cost. Disposable products are available to avoid the problem of infection. The intubation-aiding device can be used as an electronic surgical image examination instrument for penetration into a body. Moreover, a light source with tunable wavelengths can be used to increase the spot ratio of nidus.

Abstract: A self-adjusting storage rack including a plurality of coaxial coils wherein at least one pair of adjacent coils are provided with an extender to extend the storage area for flexible documents such as magazines so that they may stand in an upright position, the extender having a lower section which provides forcible contact with the coils to provide support for the extender in the upright position.

Abstract: A self-adjusting storage rack for holding vertically stationery, envelopes, letters, file folders, cards, photos, magazines and similar flat surface articles. The device comprises of two upright ends mounted on a base of two flat telescopic rods; a third central telescopic rod acts as a guide for a elastic, expandable and continuous multi-coil; each end coil is attached to an upright end so that one upright may be manually pulled out, extending the length of the rack to the full length permitted by the telescopic rods or any length in between. The elastic coil between the two uprights adjust itself accordingly.
