The numbers of bits within the MAP-IEs in at least the DL_MAP and optionally also the UL_MAP of each frame, used to represent the Symbol offset and No. of Symbols, are scaled to the frame duration and the subcarrier allocation scheme used for the zone to which the DL-MAP_IE is associated.

Reduced memory vectored DSL
The memory storage, transmission and processing demands of a vectored DSL system are reduced by sampling a subset of DSL tones in the DSL tone range used in the vectored system. This data is smoothed (denoised) to further reduce the data's size, sacrificing some fidelity or precision as a result. Finally, lossless entropy coding or the like is performed to encode the FEXT cancellation data for storage and use. The resulting data is less likely to cause transmission bottlenecks in the vectored system, can be stored and used more efficiently for both on-chip and off-chip vectoring implementations, and can be readily updated in various ways. |

Optical disc device
The optical disc device has a circuit which forms a focus error signal for focus servo control based on reflection light from an optical disc exposed to laser light. Also, the device has a data processing unit which can control by feedback a position to which an objective lens is moved by a focusing actuator based on a focus error signal. In label printing, the data processing unit controls, by feedforward, a position to which the objective lens is moved by the focusing actuator based on control data for label printing. The operation resolution of the focusing actuator in feedforward control is made higher than that in feedback control. Thus, an intended position control accuracy is achieved in feedforward control. For instance, in feedforward control, the gain of the driver circuit for the focusing actuator is switched to a smaller one in comparison to that in feedback control. |

Magnetic field generator
A metallic ring is made of two metals, wherein one metal forms a major arcuate portion and the other a minor arcuate portion of the ring, thereby forming a thermocouple-type structure as a result of the two inter-metallic junctions. The metallic ring supports a surface plasmon whose energy is matched to the energy, i.e. wavelength, of an incident light beam so that the oscillating electromagnetic field of the light resonates with the plasmon. The resonating plasmon causes a temperature difference to arise between the two inter-metallic junctions in the ring. The different Seebeck coefficients of the two metals results in the temperature difference causing a net current to flow around the ring, which in turn generates a magnetic field. Such a thermoelectric metamaterial ring transforms high frequency optical energy into long duration magnetic radiation pulses in the terahertz range. Applications of these devices include high density magnetic recording, magnetic field spectroscopy, and efficient terahertz radiation sources. |

A NAND Flash based content addressable memory (CAM) is used for a key-value addressed storage drive. The device can use a standard transport protocol such as PCI-E, SAS, SATA, eMMC, SCSI, and so on.

The drive then maintains a table linking the keys to location of the value. In a read process, the host provides a key to drive, which then broadcasts down the word lines of blocks storing the keys. Based on any matching bit lines, the tables can then be used to retrieve and supply the corresponding data to the host. This arrangement can be applied to de-duplication: for data sets stored in a primary data storage section, corresponding data keys can be generated and store in search NAND. A received key, rather from external to the system or internally generated, can then be compared against the search NAND. The system can be applied to both in-line and off-line de-duplication. |

Method for the generation of an image in electronic form, picture element (pixel) for an image sensor for the generation of an image as well as image sensor
A method for continuously generating a (grayscale) map of a scene in electronic form, characterized by high time resolution and minimal data volume, is presented. The method involves repeated measurement of the instantaneous exposure of the image elements in an image sensor, the start of every exposure measurement being determined autonomously and asynchronously by every image element independently, and hence the redundancy which is typical of synchronous image sensors in the image data to be transmitted being largely suppressed.The stimulation for the purpose of exposure measurement is provided by the autonomous detection of a relative light intensity change in the scene detail which the image element views, by the transient detector in the respective image element. To increase the signal-to-noise ratio and the dynamic range, the exposure measurement is preferably performed on the basis of time, that is to say the exposure of an image element is represented by the period between two asynchronous events.The address of the image element, corresponding to the coordinates of the image element in the sensor array, is transmitted asynchronously at the time of every detection of a light intensity change for the purpose of storage and/or further processing. In addition, the result of the resultant exposure measurement is likewise transmitted together with the address of the image element, asynchronously for the purpose of storage and/or further processing.No external control signals are required for controlling timing, particularly for the exposure measurement. The image sensor is typically implemented in CMOS technology. |
