Non-Volatile Memory And Method With Post-Write Read And Adaptive Re-Write To Manage Errors
ActiveUS20110099460A1Small marginImprove performanceMemory loss protectionRead-only memoriesHigh densityLow density
Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. Input data is written and staged in the first portion before being copied to the second portion. An error management provides checking the quality of the copied data for excessive error bits. The copying and checking are repeated on a different location in the second portion until either a predetermined quality is satisfied or the number or repeats exceeds a predetermined limit. The error management is not started when a memory is new with little or no errors, but started after the memory has aged to a predetermined amount as determined by the number of erase / program cycling its has experienced.

A portable communicator for operating a field device. The portable communicator is configured to communicate with the field device to configure and / or analyze performance of a field device in an efficient manner. In some embodiments, the portable communicator includes an intuitive user interface that allows the user to perform a relatively limited set of preconfigured procedures on a field device. The portable communicator may communicate with the field device via a wire and / or wirelessly. In one embodiment, the portable communicator is a Bluetooth-enabled smartphone, a PDA, a pocket PC, or any Bluetooth-enabled generic mobile communication device. The portable communicator may communicate with the field device via a wireless communication unit (e.g., Bluetooth modem) coupled to the field device. In a process plant environment, in which the field device is coupled to a controller, the portable communicator may communicate with the field device without communicating with the controller.

Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. An error management provides reading and checking the copy after copying to the second portion. If the copy has excessive error bits, it is repeated in a different location either in the second or first portion. The reading and checking of the copy is accelerated by reading only a sample of it. The sample is selected from a subset of the copy having its own ECC and estimated to represent a worst error rate among the copy it is sampling. One embodiment has the sample taken from one bit of each multi-bit memory cell of a group.

Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. For acceptable quality assurance, conventional error correction codes (“ECC”) have to correct a maximum number of error bits up to the far tail end of a statistical population. The present memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. If excessive error bits (at the far tail-end) occur after writing a group of data to the second portion, the data is adaptively rewritten to the first portion which will produce less error bits. Preferably, the data is initially written to a cache also in the first portion to provide source data for any rewrites. Thus, a more efficient ECC not requiring to correcting for the far tail end can be used.

Transmitter Apparatus and Method for Transmitting Packet Data Units in a Communication System
InactiveUS20080165671A1Improve transmission performanceReduce the sensitivity valueError preventionModulated-carrier systemsCommunications systemComputer science
In a communication system, when packet data units (PDUs) to be transmitted from a transmitter apparatus are modulated according to Orthogonal Frequency Division Multiplexing (OFDM), the waveforms representing the modulated PDUs will experience different peak to average ratio values (PAR) making the PDUs differently sensitive to non-ideal transmitter characteristics. To minimize errors in the transmitted PDUs, at least two PDUs (304, 305, 306) are scrambled and modulated in parallel and substantially simultaneously in the transmitter (100), and the PAR values of the at least two PDUs (304, 305, 306) are determined at each transmit instance. The measured PAR values of the at least two PDUs are compared in a scheduler (310), and the scheduler selects for transmission the PDU with the lowest PAR value. The scheduler (310) then instructs the transmitter (100) to transmit the selected PDU. If the PDUs that were not selected for transmission are re-scrambled and re-modulated before they are transmitted, the average PAR value for a transmitted PDU can be lowered by 2-3 dB with the invention if 8 PDUs are compared at each transmit instance.

Processes and apparatuses analyze an image of a maze pattern in order to extract bits encoded in the maze pattern by iteratively obtaining a perspective transform from the captured image plane to the paper plane. The embedded interactive data is recognized by obtaining a perspective transform between the captured image plane and paper plane based on an obtained affine transform. The perspective transform typically models the relationship between two planes more precisely than the affine transform. The number of error bits in the extracted bit matrix is typically reduced, thus enabling decoding of position information to be more efficient and robust.

Methods and systems are provided to reduce the effects of impulse noise in decoding a received OFDM signal by reducing the bit error number in burst error positions and by reducing the impulse noise contribution to channel estimation. In order to reduce the performance degradation due to impulse noise, it is important to find the position or the OFDM symbol where impulse noise occurs. The high noise variance gain can then be used for a Viterbi decoder to reduce the bit error number in burst error position, and also to reduce the contribution of the channel estimation by impulse noise in future channel estimations. Accordingly, the performance of the system can be greatly improved.

This invention describes a method for a new methodology for double-phase keys used to minimize pressing-key errors in electronic devices (e.g., portable communication devices, mobile phones, etc.). During the first phase, the key is pressed, e.g., half-way without actually sending the information to an active application. When the user presses the key half-way, the operating system of the electronic device provides to the user an audio feedback about the identity of the pressed key. The user can then either move the finger from the key (if it is not an intended key) or press the key all the way down (if it is the intended key). When the key is pressed down fully (the second phase), the appropriate active application actually receives the intended message / command (e.g., a number / character used in the active application) and the electronic device provides to the user an audio feedback confirmation of the fully-pressed key.
