Title: Turbo product code decoder
Inventor: HEWITT ERIC
IPC: H03M13/00
Filed: 1999-09-27
Abstract: The present invention is a turbo product code decoder capable of decoding multi-dimensional coding schemes. The decoder may be implemented in any digital communication system capable of receiving an encoded stream of data. The decoder is configured for receiving soft decision values. The decoder iteratively decodes the data by generating new soft difference values for each axis-iteration of decoding. These soft difference values represent the change in soft decision values after each axis-iteration. The soft difference values from each axis-iteration are then summed with the original soft decision values in decoding each of the other axis. After any full iteration - i.e. after all axis dimensions have been decoded one full time, the previous difference values for any axis are discarded when that axis is decoded in subsequent iterations.  Accordingly, the same information is not continuously fed into the decoder during each subsequent iteration, thereby decreasing the likelihood of error and offering an improvement over prior decoders. Moreover, using unique nearest neighbor computation logic, the decoder of the present invention is able to generate valid nearest neighbors more efficiently without requiring the use of a look-up table, thereby reducing the amount of time required to decode. Finally, the decoder of the present invention utilizes four decoders arranged in parallel along with a unique memory array accessing scheme such that multiple rows or columns may be decoded at the same time, thereby increasing the data throughput time of the decoder over prior turbo product code decoders.

Title: Method for cell alignment and identification and calibration of robot tool
Inventor: STENBERG BJORN
IPC: B25J9/22
Filed: 1999-12-17
Abstract: The invention concerns a method of cell alignment and identification and calibration of a robot tool. According to the method a robot part, preferably a part of the robot tool, is positioned close to a detector, whereupon it is moved repeatedly past the limit of the area of detection of the detector. During the movement, the pose of the robot is registered each time the surface of said robot tool comes into tangential contact with the area of detection, and an over determined system of equations is formed, consisting of a correlation between the registered poses and unknown parameters regarding the detection area of the detector and the location of the robot part in space. An error vector is introduced into the system of equations, which is then solved while minimizing the error vector, preferably in the least square sense, in order to thus identify said unknown parameters and the error vector.

Title: Article irradiation system in which article transporting conveyor is closely encompassed by shielding material
Inventor: ALLEN JOHN THOMAS
IPC: A61L2/08
Filed: 2000-09-21
Abstract: Articles are transported by a conveyor system in a loop from a loading area past a target region to an unloading area adjacent the loading area. A first side of the article is irradiated by a radiation source in the target region during the article movement through the target region. The radiation source may be substantially parallel or perpendicular to the conveyor system. The loop has curved portions and straight portions between the curved portions. Radiation shielding material substantially fills the space within the loop. The conveyor system and the radiation source are disposed within a chamber made from a radiation shielding material (e.g. concrete). The shielding material inside and outside the loop defines a radiation-free loop portion having straight portions with a relatively close spacing. A bridge having no radiation shielding and a relatively short length is disposed in this radiation-free area as are the loading and unloading areas. The bridge rotates the articles through an 180° angle after the irradiation of the first side of the article and transfers the articles to the conveyor system at a position before the target region to obtain another movement of the articles past the radiation source and an irradiation of the second side of the articles. After such irradiation, the articles are transferred to the unloading area.

Title: Method and apparatus for adaptively suppressing noise
Inventor: MARCHOK DANIEL J
IPC: G10L21/02
Filed: 2000-01-07
Abstract: An apparatus and method for suppressing noise is presented. The apparatus may utilize a filter bank of bandpass filters to split the input noisy speech-containing signal into separate frequency bands. The overall average noise-to-signal ratio (NSR) of the input signal is estimated in the overall NSR  estimator, which estimates the average noisy signal power in the input signal during speech activity and the average noise power during silence. Two indirect power measures are performed for each band, measuring a short-term power and a long-term power. The power estimation processes are adapted based on the signal activity indicated by the JVADAD. An NSR adapter adapts the NSR  for each frequency band based on the long-term and short-term power measures, the overall NSR and the signal activity indicated by the JVADAD. The gain computer utilizes these NSR values to determine the gain factors for each frequency band.
