Hybrid ARQ for packet data transmission
InactiveUS6977888B1Improve throughputReduce delaysError prevention/detection by using return channelTransmission systemsCommunications systemForward error correction
A hybrid ARQ scheme is used incremental data packet combining. In an example embodiment, the hybrid ARQ scheme with incremental data packet combining employs three feedback signaling commands: ACK, NACK, and LOST. Using these three feedback commands, the hybrid ARQ scheme with incremental data packet combining provides both robustness and good performance. This scheme is particularly advantageous in communication systems with unreliable communication channels, e.g., a fading radio channel, where forward error correction (FEC) codes are used and some of the code symbols are more important than other code symbols. Benefits include increased throughput and decreased delay of the packet data communication.

An RF-energy modulation system dynamically adjusts tuned receiving circuits within a plurality of slave devices, thereby regulating the level of power reception in each slave device. The slave devices receive power from a single master device, through coupling of a primary antenna in the master device with a secondary antenna in each slave device. The amount of the power received by each slave device is a function of the antenna separation distance, and is thus different at each slave device location. The RF-energy modulation system monitors the power requirements of the slave device within which the modulation system is included, and modulates the tuning of the secondary antenna to maintain the proper power reception level. Advantageously, such modulation controls the power reception by the slave device, versus dissipating energy already received by the slave device. In a preferred embodiment, the RF-energy modulation system controls the power received by a multiplicity of microstimulators implanted in a single patient.

Motion capture system with a motion capture element that uses two or more sensors to measure a single physical quantity, for example to obtain both wide measurement range and high measurement precision. For example, a system may combine a low-range, high precision accelerometer having a range of −24 g to +24 g with a high-range accelerometer having a range of −400 g to +400 g. Data from the multiple sensors is transmitted to a computer that combines the individual sensor estimates into a single estimate for the physical quantity. Various methods may be used to combine individual estimates into a combined estimate, including for example weighting individual estimates by the inverse of the measurement variance of each sensor. Data may be extrapolated beyond the measurement range of a low-range sensor, using polynomial curves for example, and combined with data from a high-range sensor to form a combined estimate.

NAND flash memory device with ecc protected reserved area for non-volatile storage of redundancy data
InactiveUS20080065937A1Reduces silicon area requirementMeet cutting requirementsError detection/correctionStatic storageHamming codeArray element
Basic redundancy information is non-volatily stored in a reserved area of an addressable area of a memory array, and is copied to volatile storage therein at every power-on of the memory device. The unpredictable though statistically inevitable presence of failed array elements in such a reserved area of the memory array corrupts the basic redundancy information established during the test-on wafer (EWS) phase of the fabrication process. This increases the number of rejects, and lowers the yield of the fabrication process. This problem is addressed by writing the basic redundancy data in the reserved area of the array with an ECC technique using a certain error correction code. The error correction code may be chosen among majority codes 3, 5, 7, 15 and the like, or the Hamming code for 1, 2, 3 or more errors, as a function of the fail probability of a memory cell as determined by the EWS phase during fabrication.
