Abstract:
There is provided an electronic paper display device and a manufacturing method thereof. The electronic paper display device includes a first substrate formed of a light transmitting material; a second substrate disposed to face the first substrate having a predetermined gap therebetween; at least one or more rotatable balls disposed between the first and second substrates and having electrical and optical anisotropy; and partitions dividing a space between the first and second substrates into a plurality of cell spaces accommodating the rotatable balls. The partitions are disposed to be spaced apart from each other with differing gaps therebetween in order to allow the cell spaces to have different sizes. When the same magnitude of voltage is applied to the rotatable balls disposed in the differently sized cell spaces, respective rotation angles of the rotatable balls become different, and accordingly a wide range of contrast levels is displayed.
Abstract:
The present invention discloses a solid bio-material for the detection of a bio-electromagnetic signal, which senses an information signal generated from living organisms and changes thereof by using fish scale, feathers of fowl and carapaces of tortoises among epidermal tissues of animals having the function of detecting, memorizing and transferring a weak information signal (bio-signal) of an electromagnetic field generated from bio-tissues, and a method for producing the same. The method for producing a solid bio-material for the detection of a bio-electromagnetic signal by using epidermal tissues of living organisms comprises the steps of: immersing the carcass of an animal with a developed epidermis such as fish, fowl, tortoises, etc. in a mixed solution of aromatics (fragrance), salt and water in the ratio of 1:2:300 for one week; separating the epidermis from the immersed living organism; washing the separated epidermis, soaking it in a mixed solution of potassium dichromate, vinegar and water in the ratio of 1:1:100 for 10 to 12 hours, applying a medium pressure thereto for 48 hours under an ambient temperature, and then drying it; applying heat of 40° C. and a cold air of −25° C. temperature in turn to the dried epidermis in a medium pressure state, two or three times in a period of 24 hours each; sterilizing the hot and cold treated epidermis by irradiating ultraviolet rays thereto with a 240 nm ultraviolet lamp for 30 minutes; generating static electricity by putting the sterilized epidermis in an electric cylinder and turning it at 500 RPM; applying pine nut oil to the outer surface of the electro statically processed epidermis; and cutting the epidermis into required sizes.

Abstract:
The present invention relates to a real-time disease diagnostic system employing a non-invasive method capable of analyzing of an electromagnetic field and variations thereof radiated from a subject. The disease diagnostic system detects a micro electromagnetic field and variations thereof radiated from bio-action potential of the living tissue, such as cells, tissues, organs and the like of a subject, as a capacitance and variations thereof using a single- or multi-channel biosensor and the disease diagnostic system including the biosensor. The disease diagnostic system analyzes the frequency obtained according to the capacitance and variations thereof and diagnoses proliferative diseases characteristic of an abnormal cell proliferation by diagnosing whole body using a non-invasive method in a short time of 10 min to 1 hour without any side effects. The disease diagnostic system displays the result of diagnosis in the form of a numerical value, sound or three-dimensional image in real time. The disease diagnosis system may be used without any of the doctor's orders for the subject, i.e., an empty stomach or taking medicine, and used to easily confirm the removal of cancer cell by surgery and the process of treatment. Therefore, the disease diagnosis system can be useful to diagnose various diseases at an early stage in a more accurate and safe manner.
Abstract:
Provided is a Vertical External Cavity Surface Emitting Laser (VECSEL). The VECSEL includes a semiconductor chip, a pump laser, a narrow bandwidth polarization filter, an external mirror, and a Second Harmonic Generation (SHG) element. The semiconductor chip includes an active layer generating light having a wavelength and a reflective layer reflecting the light generated in the active layer. The pump laser emits a pump beam for exciting the active layer. The narrow bandwidth polarization filter is formed on the semiconductor chip and polarizes the light. The external mirror faces the active layer, amplifies the light emitted from the active layer by repeatedly reflecting the light toward the reflective layer, and outputs the amplified light out of the VECSEL. The SHG element is disposed between the narrow bandwidth polarization filter and the external mirror and converts the wavelength of the light.
