20160056950 | COMMUNICATION SYNCHRONIZATION - Aspects of the present disclosure provide communications between local and remote devices having low-frequency (LF) and high-frequency (HF) circuits. As may be implemented in accordance with one or more embodiments, the local device transmits an LF signal to the remote device, which synchronizes its clock based on the LF signal. Another LF signal is communicated from the local device to the remote device using a reduced quality factor, which can be implemented to facilitate synchronization. The clock is resynchronized based on the second LF signal and used to transmit an HF signal with a time delay. The local device synchronizes its clock based on the HF signal, and transmits another HF signal to the remote device using the clock and another time delay. The remote device re-synchronizes its clock based on the second HF signal while accounting for a trip time for communicating the first and/or second HF signals. | 02-25-2016 |

20080209477 | Promotion and Degradation of Soft Erasure Information Using Crc and Proceding Decoder Information - This invention describes a system and method for assigning four levels of priority to erasures and promoting/degrading erasures by confining the number of locations to which erasures are assigned using decoder information from a preceding RS decoder and a CRC. The preceding decoder produces soft-erasure information based on blocks of 184 bytes, while the CRC can cover blocks of sizes up to 4,080 bytes whereas the invention combines the CRC with information of the preceding decoder erasures such that the combination is assigned in multiples of 184 bytes. | 08-28-2008 |

20120098428 | MESSAGE CONTROLLABLE LAMP - A lamp is provided that is controlled by messages transmitted via a network. The lamp has an internal memory that stores an address and an internal control circuit that responds to received messages that refer to this address. The address is updated when the lamp is installation in a power supply socket, using for example an address from the first message that is transmitted after installation. The lamp contains a detector that detects disconnection of the lamp from the power supply socket, for example by monitoring a resistance value between two parts of one of the power supply terminals of the lamp. In response to this detection the control circuit of the lamp sets information that enables an update of the address in the memory. When it is detected that the lamp is again connected to a power supply socket the address is updated on condition that the update is enabled. | 04-26-2012 |

20130279558 | REDUCED LATENCY CHANNEL-ESTIMATION - Receiving an OFDM signal having a series of OFDM symbols, each having sub-carriers, each modulated by at least one data bit encoded with error-correcting code. The receiver has a first error-correcting decoder to decode sequentially data bits of a received first OFDM symbol; a re-encoder to receive decoded bits and re-encode a leading portion of the decoded bits; a mapper to receive the re-encoded leading portion of bits, map these bits to a corresponding subset of the sub-carriers, and thereby estimate a modulation symbol applied to each sub-carrier, by the transmitter; a channel estimator to produce a channel estimate by comparing sub-carrier modulation symbols with corresponding sub-carriers received by the receiver; and an equalizer to process the received signal to remove distortions from the transmission channel, using the channel estimate. The re-encoder begins re-encoding the leading portion of the bits before a trailing portion has been decoded. | 10-24-2013 |

Thereby, a cyclic or non-cyclic memory model for a memory unit ( | 10-23-2008 |
20160036499 | COOPERATIVE ANTENNA-DIVERSITY RADIO RECEIVER - Various exemplary embodiments relate to a wireless communications system related method and vehicle including: a first communications device configured for attachment to a vehicle including: a first antenna group, a first receiver configured to receive a first instance of a message via the first antenna group, a first transmitter configured to transmit a second instance of the message via the first antenna group, and a first controller configured to cause transmission of the second instance via the first transmitter in response to the first receiver receiving the first instance; and a second communications device configured for attachment to the vehicle including: a second antenna group, a second receiver configured to receive data via the second antenna group, wherein the second receiver receives both the first instance and the second instance, and message combination circuitry configured to generate combined message by combining the first instance and the second instance. | 02-04-2016 |
