摘要： The present invention relates to surfacing material which may emit radiation in response to exposure to a given light source. Such surfacing material may be polymeric based, and e.g., fiber based, and may be used in relatively low-light areas, including low-light areas as applied to vehicular applications. The fiber-based or molded materials may emit radiation in response to exposure to a selected light source and may be used in relatively dimly lit areas. The materials may also provide a visible contrast to other objects located adjacent their surface which do not emit radiation. Optical brighteners and luminous particles may be included in the materials to make them luminous.

摘要： A system and method for communicating wirelessly from a mobile device to a remote receiver station is disclosed. The system includes a controller configured to monitor a status of the mobile device and, upon an initiation event, initiate a data transfer process to wirelessly communicate data to the remote receiver station. The system also includes a voice-band modem that, upon initiation of the data transfer process. The voice-band modem is configured to receive data for transfer to the remote receiver station, encode the data to form a series of encoded packets, and transmit the encoded packets to the remote receiver station using a first modulation scheme. Thereafter, unless an indication that the series of packets has been received by at the receiving station is provided, the voice-band modem automatically retransmit the encoded packets to the remote receiver station using a second modulation scheme.

摘要： Apparatus and method for allocating communication resources in a data radio communication system, such as an MAIO (Mobile Allocation Index Offset) communication system, e.g., a communication system that provides for Enhanced Data for GSM Evolution (EDGE) data services. A multi-carrier radio resource control logic element includes an analyzer that analyzes communication resource requirements to carry out a communication service. A resource allocator allocates communication resources to be used by which to communicate the data. The communication resources are allocated across a plurality of radio carriers such that resources are allocated, during a particular time period, upon a single radio carrier of the plurality of radio carriers.

摘要： A receiver and associated method estimates a channel impulse response of the communications signal. A communications signal is received as a burst of transmitted symbols, including a known training sequence. The joint estimation of timing offset and initial channel impulse response is determined based on the cross-correlations of the known transmitted symbols and received communications signal. A constant modulus interference removal iteration is applied to improve the initial channel impulse estimation.

摘要： Various embodiments are described herein that make use of a lost frame concealment method for processing data frames received from transmission over a communications channel. The method involves determining whether a current data frame is a bad frame, performing source decoding on the current data frame with one or more parameters that are limited by a first set of one or more values if the current data frame is a bad frame, and performing source decoding on the current data frame with one or more parameters that are not limited if the current data frame is a good frame.
