System and method for grouping claim records associated with a procedure
A system and computer-implemented method for grouping medical records implements a multi-level analysis of the records. The level of analysis for each record is determined based upon the time proximity of each record to the defining medical procedure or service (anchor procedure) to be analyzed. Once an anchor procedure is identified, claim records are processed to determine whether any of the records should be grouped with the anchor procedure into a procedure episode group (PEG). First, the date of service for each claim record is identified to determine whether the claim record falls within time window. The claim records falling within the window then are assessed to determine whether each claim record is sufficiently related to the anchor procedure (for example, by determining whether the diagnostic, procedure, or episode treatment group coding of each claim record is associated with the anchor procedure). The requisite level of relationship between the claim records and the anchor procedure depends upon the position of the records within the time window. Only those claim records having the requisite relationship level associated with the portion of the time window in which they fall are included in the PEG. |

Scheduling of uplink data transmission using different UE-IDS
A radio terminal adjusts its data transmit power in response to received power control commands which specify a maximum transmit power level. The commands may be addressed to an individual radio terminal by means of a first address, or addressed to a group of radio terminals by means of a second address. In order that the data transmit power of an individual radio terminal is not disrupted by the commands addressed to a group, the radio terminal operates in two states. In the first state the radio terminal responds to commands comprising the first address and does not respond to commands comprising the second address. In the second state the radio terminal responds to commands comprising the second address. The radio terminal transfers from the first state to the second state in response to receiving a command comprising the first address and a predetermined value. On entering the second state the transmit power is set in accordance with the last-received command comprising the second address, thereby avoiding the need for transmission of a further command comprising the second address before transmission in the second state can proceed. Alternatively, or additionally, transmission rate may be controlled in the same manner. |

Method and system for adjusting downlink outer loop power to control target SIR
A wireless communication system and method for controlling transmission power to maintain a received signal-to-interference ratio (SIR) as close as possible to a target SIR. A received quality is maintained as close as possible to a target quality based on block error rate (BLER). When a target BLER is converted to an initial target SIR, an error may occur due to a channel condition mismatch, since the target SIR required for the target BLER varies with channel conditions. An outer loop power control process is used to set a target SIR for each coded composite transport channel (CCTrCH) based on the required target BLER. The process adjusts a SIR step size parameter to maximize the convergence speed of the process. |

Motion estimation technique for digital video encoding applications
The present invention provides an improved motion estimation encoder for digital video encoding applications. In one example embodiment, the improved encoder receives a raw image in the form of a current frame and estimates the macroblock motion vector with respect to a reference frame. The encoder then performs an initial local search around an initial motion vector candidate derived from spatio-temporal neighboring macroblock parameters. The encoder then compares the user-defined complexity scalable sum of absolute difference between the original and the associated reference macroblock against an adaptive threshold value for motion estimation convergence. The encoder introduces a global full search around a candidate from a coarser level, in case an initial local search fails. The encoder then selects an inter encoding mode for coding the current macroblock, when the first local search is successful, otherwise the encoder selects the inter or intra encoding mode for encoding the current macroblock by comparing variances of the original and difference macroblocks. |

Method and apparatus for rate fallback in a wireless communication system
A method and apparatus are disclosed for reducing a transmission rate for retransmission of a current frame in a wireless communication system. The reduced transmission rate increases the probability that the current frame is correctly transmitted and acknowledged. The transmission rate is progressively reduced for the current frame to avoid the expiration of the frame's retry count, while not affecting the transmission rate of subsequent frames. The next frame should be transmitted at the highest rate permitted by the signal quality. A disclosed retry count expiry avoidance algorithm increases the reliability of a retransmission by lowering the transmission rate for the current frame when an acknowledgement is not received. When an acknowledgement is not received, the transmitting station proceeds to a retransmitting state where the transmitting station first attempts to retransmit the frame at the same rate. When the number of “equal rate attempts” is exceeded, the retry count expiry avoidance algorithm enters to a fallback state, where the transmission rate is decreased in a progressive manner. |

Method for index programming and reduced verify in nonvolatile memory
In a non-volatile memory a group of memory cells is programmed respectively to their target states in parallel using a multiple-pass index programming method which reduces the number of verify steps. For each cell a program index is maintained storing the last programming voltage applied to the cell. Each cell is indexed during a first programming pass with the application of a series of incrementing programming pulses. The first programming pass is followed by verification and one or more subsequent programming passes to trim any short-falls to the respective target states. If a cell fails to verify to its target state, its program index is incremented and allows the cell to be programmed by the next pulse from the last received pulse. The verify and programming pass are repeated until all the cells in the group are verified to their respective target states. No verify operations between pulses are necessary. |

Text/Image data transfer method
When performing Push-type data transfer from the side of an image-supply apparatus 100 to a printer 200P, it is necessary for the printer 200P to have a buffer that is capable of containing at least the capacity for one page of data. Therefore, the text/image-supply apparatus 100 stores printing-description data obtained from the application on its own memory unit 105. The image-formation apparatus 200 performs rasterization based on received printing-description data, however, in this process, when there is a link file L that is linked to the top file T of the printing-description data, the image-formation apparatus 200 specifies the link destination and sends a data-acquisition request to the text/image-supply apparatus 100, so there is no need for a buffer. |
