Echo cancellation for duplex radios
In a Frequency Duplex Division (FDD) radio, the transmit and receive signals are separated by frequency. In a wireless application, the power of the transmitted signal is typically much larger than the power of the received signal. A duplexer is used to separate the transmit and receive signals. Despite the operation of the duplexer, a residual transmit signal, or echo, can be present at the receiver input as a result of finite attenuation in the duplexer and other sources of transmit to receive crosstalk. With a relatively linear low-noise amplifier (LNA) and output limited mixer linearity, the echo can be cancelled in analog baseband directly at the mixer output using an out-of-channel signal indicator as the error signal for an echo control loop. |

Forecasting program disturb in memory by detecting natural threshold voltage distribution
Program disturb is reduced in a non-volatile storage system during a programming operation by determining a susceptibility of a set of storage elements to program disturb and taking a corresponding precautionary measure, if needed, to reduce the likelihood of program disturb occurring. During programming of a lower page of data, a natural threshold voltage distribution of the set of storage elements is determined by tracking storage elements which are programmed to a particular state, and determining how many program pulses are need for a number N1 and a number N2>N1 of the storage elements to reach the particular state. Temperature and word line position can also be used to determine the susceptibility to program disturb. A precautionary measure can involve using a higher pass voltage, or abandoning programming of an upper page of data or an entire block. In some cases, programming continues with no precautionary measure. |

Electrochromic elements using antioxidants to suppress self-discharging
The invention relates to the use of antioxidants of different kinds and concentrations in electrochromic elements having an ion conducting component to suppress self-discharging. In comparison to electrochromic elements known from prior art, electrochromic elements according to the invention show a significantly smaller increase in transmissivity for a period of time after the electric current necessary to decrease transmissivity is switched off. The use of sterically hindered amines and/or 1,3,5-trisubstituted phenols has proven particularly effective for this purpose. |

Minimizing visual artifacts in a brick-layer halftone structure
What is disclosed is a novel system and method for minimizing visual artifacts, such as ROS skew and laserbeam bow, in a brick-layer halftone structure. The present method involves determining a line pattern from ROS skew and laserbeam bow profiles which traverses through successive halftone cells displacing pixels along scanlines in the process direction.

In each halftone cell within which the line pattern traverses, extra pixels (empty pixel spaces created in the halftone cell by the shifting operation) are filled with lost pixels (pixels bumped from the halftone cell during the shifting operation) such that overall density of the halftone cell is maintained. The lost pixels are buffered such that lost pixels are preserved. |

Method and apparatus for selecting an operating mode based on a determination of the availability of internal clock signals
A system and method to operate an electronic device, such as a memory chip, with an output driver circuit that is configured to include an ODT (On-Die Termination) mode detector detects whether there is sufficient internal clocking available to operate the ODT portion in the output driver in the synchronous mode of operation or to switch the operation to the asynchronous mode.

Unlike buck converter and tapped-inductor buck converters, which use only inductive energy transfer, the present invention employs the capacitive energy transfer in addition to inductive energy transfer.

The use of solid strong cationic catalysts in this reaction system is advantageous because they remain as solids throughout the reaction, allowing simplified separation of the solid catalyst from the soluble AMS or co-AMS products, resulting in total or near total recovery of the AMS or co-AMS products, the products being free of, or substantially free of residual acid catalyst, as well as virtual total recovery of the catalyst for recycling. The improved AMS and co-AMS compounds, vulcanizable rubber compounds containing them, and a pneumatic tire having a component made from the vulcanized rubber compounds are also presented. |
