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 thermopile IR detector package structure makes use of the silicon micro-electro-mechanical processing technique fabricate an encapsulation having a cavity. The encapsulation is then installed onto a substrate of a detector to seal thermoelectric components on the substrate. In addition to having the sealing function, the encapsulation also has the function of detecting the spectrum and field of view. Next, a carrier substrate is combined with sensing components to form a surface mount device applicable to assembly and fabrication of various related circuits. The thermopile IR detector package structure not only facilitates mass production and reduces fabrication process, material, volume ad weight, but the formed surface mount device is also in agreement with automatically produced electronic components.

Abstract: The design methods and apparatuses of photodiodes with adaptive structures to achieve smooth and wavelength-selective responses are proposed. By using the adequate sizes of the photo-sensing areas and gains of the back-end amplifiers towards the different photo-responses of multiple photodiodes, the photo-responses from these photodiodes are summed together to yield the uniform distribution of the total photo-responses. Based on the physical characteristics of the process parameters, the equation of the photo-responses for the PN junction is derived to find the optimized values of the process parameters for increasing the photo-response and achieving the peak value of the photo-responses at a specific wavelength. The photodiode with multiple PN junctions and multiple switches is designed to achieve multiple photo-responses in a single photodiode. By using the switches to turn off the unused PN junctions, the selected PN junctions can generate the required photo-responses.
