An apparatus for optical sensing of samples includes an optical source, an optical assembly, a sample holder, an objective lens, and a detector. The objective lens collimates light emitted by the sample. Preferably, the optical assembly rotates about an axis, allowing the sensing apparatus to sense results from plural locations on a sample without moving the sample. Moving the sample in a linear direction while rotating the optical assembly allows sensing of an entire sample. Preferably, light from the optical source enters the optical assembly along the axis of rotation. Sensing methods consistent with the invention are also described.

A hermetic compressor capable of preventing malfunction due to impurities trapped between contact portions of a crankshaft and a crankshaft supporting frame when the crankshaft rotates in a hollow portion of the frame. The hermetic compressor comprises the frame having the hollow portion, the crankshaft rotatably inserted in the hollow portion, a balance weight provided at one end of the crankshaft, and a thrust portion formed at the frame to support the crankshaft. An impurities discharge passage is formed at an outer circumferential surface of the crankshaft that comes into frictional contact with the thrust portion of the frame to guide impurities, mixed with the oil, out of the crankshaft. Correspondingly, a plurality of discharge guiding grooves is formed at the thrust portion of the frame to guide the oil and the impurities, having passed through the impurities discharge passage of the crankshaft, out of the thrust portion.

The present invention relates to a plasma display apparatus, and more particularly, to a plasma display apparatus and driving method thereof, wherein a sustain waveform can be improved. According to the present invention, the plasma display apparatus includes a plasma display panel comprising a plurality of sustain electrode pairs wherein each of the sustain electrode pairs has a scan electrode and a sustain electrode, and a sustain waveform controller for controlling a rising time or a falling time of sustain waveforms supplied to at least one of the sustain electrode pairs according to a temperature of the plasma display panel. The sustain waveform controller controls a time corresponding to a time point at which a sustain discharge is generated, of the rising time and the falling time. The present invention improves a plasma display apparatus and driving method thereof. Accordingly, there is an effect in that erroneous discharge depending on a temperature of a plasma display panel can be prevented.

A system for controlling a linear compressor, generates freezing force as a piston reciprocates according to rotation of a motor which receives alternating current power through a triac. The system includes a controller which moves up or delays a trigger signal corresponding to an absorption cycle or a compression cycle, such that the center point of the piston reaches a resonant point when a current and a phase difference of the motor deviate from predetermined ranges.

An apparatus and method for decoding digital stream data includes detecting a discontinuous period of digital stream data stored in a buffer, such that upon detection of the discontinuous period, a further operation includes decoding all currently stored portions of the digital stream data in the buffer using non-updated reference time information. The non-updated reference time information may be defined as the reference time information used for decoding the digital stream data prior to the discontinuous period. An additional operation includes decoding remaining portions of the digital stream data using updated reference time information.

The invention relates to a flip-chip nitride semiconductor LED. In the LED, a light emitting structure has first and second conductivity type nitride semiconductor layers and an active layer interposed therebetween. Each of plurality of first and second electrodes has a bonding pad placed adjacent to a top corner of the light emitting structure and at least one electrode finger extended from the bonding pad. The first and second electrodes are connected to the first and second conductivity type nitride semiconductor layers, respectively. Also, bonding pads are arranged alternately along edges of the light emitting structure with different polarity, in a substantially symmetric configuration with respect to the center of the light emitting structure. In addition, each of electrode fingers is extended from a corresponding pad and bent at least once toward the center of the light emitting structure to adjoin the electrode finger having different polarity.
