This allows existing hardware to be conveniently leveraged to provide a self contained system which does not depend on the on-site labor of rare and expensive system integration and security experts.

The invention relates to method for buffering encoded pictures. The method includes an encoding step for forming encoded pictures in an encoder. The method also includes a transmission step for transmitting said encoded pictures to a decoder as transmission units, a buffering step for buffering transmission units transmitted to the decoder in a buffer, and a decoding step for decoding the encoded pictures for forming decoded pictures. The buffer size is defined so that the total size of at least two transmission units is defined and the maximum buffer size is defined on the basis of the total size.

Systems and methods are provided for decoding signal vectors in multiple-input multiple-output (MIMO) systems, where the receiver has received one or more signal vectors from the same transmitted vector. The symbols of the received signal vectors are combined, forming a combined received signal vector that may be treated as a single received signal vector. The combined signal vector is then decoded using a maximum-likelihood decoder. In some embodiments, the combined received signal vector may be processed prior to decoding. Systems and methods are also provided for computing soft information from a combined signal vector based on a decoding metric. Computationally intensive calculations can be extracted from the critical path and implemented in preprocessors and/or postprocessors.

Disclosed is an encoding/decoding apparatus of a HARQ system using LDPC codes. A first LDPC code encoding apparatus encodes input information data and transmits the encoded data to the decoding apparatus. An interleaver interleaves the input information data. A second LDPC code encoder in parallel with the first LDPC code encoder performs LDPC code encoding on an output of the interleaver so as to transmit it to the decoding apparatus. The first LDPC code encoder transmits an output signal to the decoding apparatus at odd numbered retransmissions in response to a retransmission request from the decoding apparatus, and the second LDPC code encoder transmits an output signal to the decoding apparatus at even numbered retransmissions in response to the retransmission request from the decoding apparatus.

At least one face is coupled to the centre point. The at least one face has a motion-guiding module to define a trajectory over at least part of the face, and a motion-restriction module to limit the displacement of the centre point with respect to the centre point of one of the other elements. At least one trajectory includes the trajectory and a trajectory of the other element when interacting with the motion module.

An improved method and apparatus for a liquid filling system is herein disclosed incorporating means for generating greater overall production rate efficiencies (i.e. number of filled containers per minute per filling station) for automatic systems utilizing diverter valve and/or walking beam (i.e. continuous-motion) filling technologies with, for example, non-traditional ratios between the number of filling stations and the number of filling nozzles. The methods/apparatus disclosed herein also incorporate means to more efficiently changeover and clean up, in either a clean-in-place (CIP) or clean-out-of-place (COP) configuration, the product contact parts that become “dirty” when used in a production environment. Finally, an improved method and apparatus designed to provide a means for priming and air purging the product contact path of liquid filling machinery, a fill volume calibration procedure, and a fill weight verification cycle is also herein described.

A multiple access digital communication method in ultra-wideband (UWB) radio access network is provided. More specifically, a multiple access technique in UWB communication channels is provided where UWB communication channels can be more efficiently used and collisions between multiple access user nodes can be more effectively avoided when the channels have a great multiple path fading. The digital communication method for use in an uplink in a UWB communication system includes the steps of: receiving data symbols from respective nodes, in which the data symbols are transmitted according to respective orthogonal time hopping patterns; checking whether there is a collision of the orthogonal time hopping patterns; and decoding the data symbols depending on whether data symbols of nodes involved in the collision of the orthogonal time hopping patterns are the same.

An x-ray scanning system includes an x-ray source that produces a collimated fan beam of incident x-ray radiation. The system also includes a chopper wheel that can be irradiated by the collimated fan beam. The chopper wheel is oriented with a wheel plane containing the chopper wheel substantially non-perpendicular relative to a beam plane containing the collimated fan beam. In various embodiments, a disk chopper wheel's effective thickness is increased, allowing x-ray scanning with end point energies of hundreds of keV using relatively thinner, lighter, and less costly chopper wheel disks. Backscatter detectors can be mounted to an exterior surface of a vehicle housing the x-ray source, and slits in the disk chopper wheel can be tapered for more uniform target irradiation.

A loudspeaker system has a plurality of relatively small transducer elements configured in a closely spaced transducer array such that their acoustic outputs combine to produce a focused beam of sound in front of the array that is substantially uniform about the beams radiation axis. The transducer array lies in a plane and has a perimeter that approximates a circle, and will have fill-factor with respect to a circle circumscribing the array of at least approximately 70%. In one variation of the loudspeaker system, the transducer array is constructed in smaller transducer array modules that are operatively fitted together to produce a larger array.

An apparatus and method for distinguishing between sensors that are to be wirelessly detected is provided. An interrogator device uses different, distinct time delays in the sensing signals when interrogating the sensors. The sensors are provided with different distinct pedestal delays. Sensors that have the same pedestal delay as the delay selected by the interrogator are detected by the interrogator whereas other sensors with different pedestal delays are not sensed. Multiple sensors with a given pedestal delay are provided with different codes so as to be distinguished from one another by the interrogator. The interrogator uses a signal that is transmitted to the sensor and returned by the sensor for combination and integration with the reference signal that has been processed by a function. The sensor may be a surface acoustic wave device having a differential impulse response with a power spectral density consisting of lobes. The power spectral density of the differential response is used to determine the value of the sensed parameter or parameters.

A method for segmenting an information word into code blocks in a mobile communication system. The method includes setting a number C of code blocks to a minimum integer not less than a value obtained by dividing X by Z; when sizes K of all code blocks are determined to be equal when a length X of the information word is greater than a maximum length Z of each code block, determining a minimum integer value T not less than a value obtained by dividing a size of the information word by a number of code blocks, and determining, as K, a maximum value most approaching the value T among the values based on which a size of the code block can be set in units of eight bits; and generating a code block by inserting filler bits into a specific code block when a value obtained by multiplying K by C is greater than X.
