摘要:
A method and apparatus for temporally allocating bits between frames in a coding system such that temporal fluctuations are smoothed out. Namely, a picture quality is monitored on a frame by frame basis. An average distortion measure is derived from previous picture frames and that average is compared to the distortion measure of a current frame, where the result is used to effect bit budget allocation for each frame in an input image sequence.

A transcoding method for inserting a visual element into an encoded bit stream with minimal decoding of the encoded bit stream. The transcoding method includes the steps of receiving an encoded bit stream containing a picture, partially decoding a copy of the bit stream, determining if a segment of the picture in the bit stream is affected by the insertion of the visual element, re-encoding the segment if the segment is affected by the insertion of the visual element, and outputting the re-encoded bit stream. The encoded and re-encoded bit streams may be MPEG-encoded bit streams. The re-encoded bit stream may be output using a bit rate control process that randomly selects an initial processing point within the re-encoded bit stream, requantizes the re-encoded bit stream using a modified quantization table, and/or utilizes a slice-level stopping criteria for selectively starting or ending bit rate control.

A technique for fixing permanent magnets of a drive motor rotor for a vehicle may include inserting permanent magnets into a plurality of permanent magnet insertion holes that are formed at a predetermined distance from each other in a circumferential direction of a rotor core, applying magnetic force to the rotor core with a magnetic force generator, such that the magnetic force is formed in an axial or a radial direction of the rotor core to instantly fix the position of the permanent magnets, and adding a fixation material to the permanent magnet insertion holes to fix the permanent magnets.

A three dimensional inverted colloidal crystal scaffold is described which comprises a substrate having at least one well. The scaffold also includes a three dimensional matrix comprising a transparent biocompatible polymeric network containing microspherical voids. The microspherical voids are each connected to at least one other void through inter-connecting pores. Additionally, an apparatus for producing such a colloidal crystal scaffold is described. Methods for making the inverted colloidal crystal scaffold, for using the scaffold and for identifying the effects of a drug, pharmaceutical or toxin on a living cell using the inverted colloidal crystal scaffold are also disclosed.
摘要:
In a system for compressing video data, temporally adaptive motion interpolation based upon temporal characteristics of human vision is used for establishing threshold levels relative to the degree of motion as a whole (global motion) between frames. The global motion between successive frames in a group of pictures (GOP) is measured to determine if the motion is less or greater than the established threshold levels for determining the designation of I, P, and B frames, spacing between I and P reference frames, and the number of bits used for each frame, and B frames therebetween.

An outdoor unit bracket and an outdoor unit comprising the same, which can ensure safe and simple installation, are provided. The outdoor unit bracket includes an outer wall coupling portion, an upper supporting portion, an outer wall contacting portion, and a lower supporting portion. The outer wall coupling portion is coupled to the outer wall of the building. The upper supporting portion is coupled to a rear upper portion of the outdoor unit, being spaced apart from the outer wall coupling portion in a horizontal direction with respect to the outer wall of the building. The outer wall contacting portion contacts the outer wall of the building, being spaced apart from the outer wall coupling portion below the outer wall coupling portion. The lower supporting portion contacts a rear lower portion of the outdoor unit, being spaced apart from the outer wall contacting portion in the horizontal direction with respect to the outer wall of the building.

An indoor device for an air conditioner is provided. The indoor device may include a heat exchanger mounting panel in which an orifice to pass air therethrough is formed, a centrifugal fan to inhale air in a shaft direction through the orifice and discharge the air in a radial direction, a motor to rotate the centrifugal fan, and a case to fix the motor and couple the motor to the panel. A first magnetic substance and a second magnetic substance that generate a repulsive force may be respectively disposed at a first surface opposite to the centrifugal fan in the panel and a second surface opposite to the panel in the centrifugal fan. In the first magnetic substance and the second magnetic substance, the same pole may be formed in a concentric circle and different poles may be alternately formed in a radial direction.

A method and apparatus for selecting a beam combination of multiple-input multiple-output (MIMO) antennas are disclosed. A wireless transmit/receive unit (WTRUs) includes a plurality of antennas to generate a plurality of beams for supporting MIMO. At least one antenna is configured to generate multiple beams, such that various beam combinations can be produced and a desired beam combination selected for conducting wireless communication with another WTRU. A quality metric is measured with respect to each or subset of the possible beam combinations. A desired beam combination for MIMO transmission and reception is selected based on the quality metric measurements.
