Abstract: An imaging system lens assembly includes a first lens group and a second lens group. The first lens group includes a first catadioptric lens element and a second catadioptric lens element, the second lens group includes at least one lens element. Each of an object-side surface and an image-side surface of the first catadioptric lens element and the second catadioptric lens element includes a central region and a peripheral region. The peripheral region of the object-side surface of the first catadioptric lens element includes a first refracting surface. The peripheral region of the image-side surface of the second catadioptric lens element includes a first reflecting surface. The central region of the object-side surface of the first catadioptric lens element includes a second reflecting surface. The central region of the image-side surface of the second catadioptric lens element includes a last refracting surface.

Abstract: Hybrid pre-patterns were prepared for directed self-assembly of a given block copolymer capable of forming a lamellar domain pattern. The hybrid pre-patterns have top surfaces comprising independent elevated surfaces interspersed with adjacent recessed surfaces. The elevated surfaces are neutral wetting to the domains formed by self-assembly. Material below the elevated surfaces has greater etch-resistance than material below the recessed surfaces in a given etch process. Following other dimensional constraints of the hybrid pre-pattern described herein, a layer of the given block copolymer was formed on the hybrid pre-pattern. Self-assembly of the layer produced a lamellar domain pattern comprising self-aligned, unidirectional, perpendicularly oriented lamellae over the elevated surfaces, and parallel and/or perpendicularly oriented lamellae over recessed surfaces. The domain patterns displayed long range order along the major axis of the pre-pattern.

Abstract: The present invention provides a biosensor with finger-positioning function, comprising: a bottom plate, a cover, and a test-strip socket; wherein the cover mounted on the bottom plate has a front end provided with a guiding plate for positioning a finger, and the guiding plate has a center line and a guiding surface, in which the center line passes through a center of the guiding surface; and the test-strip socket is formed at the front end of the cover. When using the biosensor, the user can rest his/her wrist and palm on the cover of the biosensor and rest the punctured finger on the guiding surface provided at the front end of the cover to align the test strip with the blood drop on the finger so as to simplify the measurement.

Abstract: A dichromatic lens includes a plurality of zones being arranged on a lens structure, each of the zones having a specified radius and varying height. The lens structure focuses propagating light applicable to any intensity distribution for a plurality of wavelengths.

Abstract: A method for driving a light source first sets a frame time and a unit time, and calculates the number of the unit time that the frame time can contain. Based on the turned-on duration (DTi) of a light-emitting device of the light source and the unit time, the turned-on numbers (Ni) and the compensation times (CTI) of the light-emitting devices are calculated. The light-emitting device is driven to emit a light beam according to the turned-on numbers (Ni) and the compensation times (CTI). The present driving method can be applied to light source and backing light source of liquid crystal displays.
