摘要:
Disclosed herein is a Light Emitting Diode (LED) light source lens for emitting light in a lateral direction. The LED source lens includes an upper part, an upper part and a central part. The upper part includes an upper part reflecting surface bent symmetrically with respect to the central axis of the lens, and an upper part refracting surface extended from the end of the upper part reflecting surface parallel with the central axis. The central part includes a side surface extended from the lower end of the upper part refracting surface and bend inwards, and refracts or reflects light through the side surface. The lower part accommodates the LED light source, and includes an arch-shaped lower part refracting surface extended outwards from the lower end of the side surface of the central part. The light radiated from the LED light source is emitted perpendicular to the central axis.

A lens includes a convex surface formed in an outer surface thereof facing away from a light source to uniformly distribute light emitted from the light source; a concave surface concaved inward from an inner region of the convex surface, around an optical axis; and a convex portion convexed outward from a central region of the concave surface, which the optical axis intersects, in order to enhance quantity of light around the optical axis. The lens refracts light beams falling onto the respective areas thereof at different angles, thereby producing a uniform light distribution within a specific lighting range, but does not create a dark area around an optical axis.

A motion vector estimation method and continuous discrete image generation method based on a convexity property of a sub-pixel are provided. The method of estimating a motion vector includes: generating an objective function for a differential definition of a sub-pixel system composed of a chain of arbitrary n-tap filters with respect to an arbitrary k-th order sub-pixel, based on the relation between an integer pixel and a sub-pixel generated through linear FIR filtering; and estimating a motion vector of a sub-pixel by applying a conjugated quadratic algorithm to the objective function.

The invention relates to an LED package frame and an LED package incorporating the same. The LED package frame comprises an LED chip; and a heat conductive member made of a lump of high heat conductivity material. The heat conductive member has a receiving part at a lateral portion, and is mounted with the LED chip. A lead is inserted at one end into the receiving part of the heat conductive member, and electrically connected to the LED chip. An electrically insulating layer is placed in tight contact between the lead and the receiving part of the heat conductive member to separate the lead from the receiving part. With the lead inserted into the heat conductive member, it is possible to reduce size while maintaining high heat conductivity and stability. Also, it is possible to provide an LED package frame and a high power LED package by fixing the lead fixed to the heat conductive member without a jig.

This disclosure relates to methods for monitoring a database system without access to the database system, wherein when data packets between a plurality of operating servers including the database system and a plurality of client application processes are sent and/or received through a SQL net protocol or BEQ protocol, the data packets are collected through sniffing by a monitoring process or through a separate pipe gateway process thereby SQL information and database performance information transmitted between the operating servers and the client application processes are extracted. The SQL information and database performance information can be effectively monitored with no load or minimized load to the database, operating server and network.

Disclosed is a three-axial displacement measuring apparatus. The three-axial displacement measuring apparatus includes: a fixation grip fixed to one surface of a hanger supporting a structure to be measured; a universal joint connected to the fixation grip which is capable of rotating by 360 degrees; a link section being connected to the universal joint and having at least one angle sensor; an angle sensor section connected to the link section, for measuring angles; and a three-axial displacement measuring section for calculating three-axial displacement values of the measured structure by using the angle values measured by the angle sensor section.
摘要:
A CMOS image sensor with improved sensitivity includes a main pixel array region of an active pixel array region formed on a semiconductor substrate. A passivation layer is formed over the sensor, and it is at least partially removed from the main pixel array region, such that incident light being detected by the main pixel array does not pass through the passivation layer. Optical absorption and refraction caused by the material of the passivation layer are eliminated, resulting in an image sensor with improved optical sensitivity.
