摘要： Variations in x-ray beam, filtration and detector gain characteristics are corrected by a multiple thickness flattening system. Preferably, an automatic multi-position attenuator mechanism inserts into the x-ray beam one or more flat reference attenuators of uniform composition. Thereafter, the response at each detector channel is measured. Unique factors are thus collected for each channel at multiple attenuation levels. An overall uniform response across the scan field is achieved by applying these correction factors to subsequent scan data. The current system compensates for detector gain by alternately turning X-rays on and off, so that dark level measurements can be interspersed with X-ray signal measurements. Detector offsets are eliminated in a linear data representation, while beam and detector flattening corrections are applied in a logarithmic data representation.

摘要： A method of calibrating an ultrasound bone analysis apparatus having a pair of transducer assemblies. Each transducer assembly has a transducer and a coupling pad, and is movable relative to the other so that a face of each pad can be moved to a position in which they mutually contact and to a position where the faces contact body parts. The method according to the present application includes transmitting an ultrasound signal from one transducer and receiving a signal corresponding to the transmitted ultrasound signal through the other transducer when the transducer assemblies are in the first position and the second position. A time for the ultrasound signal to pass through the body part is determined, and a width of the body part based on positions of the transducers is determined. Then, using the time and width values a speed of sound of the ultrasound signal passing through the body part with squish compensation is calculated.

摘要： A wireless terminal determines a desired mode of base station operation with regard to whether the base station is to function as a network access node or is to function in a peer to peer mode with regard to a frequency band, and communicates a change signal to the base station. Some change signals are request signals requesting a base station to dynamically reallocate spectrum usage, while other change signals are command signals ordering the base station to reallocate spectrum usage. Information indicating a level of authority corresponding to the change signals, in some embodiments, corresponds to one of a device identifier, a user identifier, and a priority level indicator. An exemplary command signal comes from a device used by a government agent with the authority to override spectrum usage.

摘要： A flexible and relatively hardware efficient LDPC decoder is described. The decoder can be implemented with a level of parallelism which is less than the full parallelism of the code structure used to control the decoding process. Each command of a relatively simple control code used to describe the code structure can be stored and executed multiple times to complete the decoding of a codeword. Different codeword lengths are supported using the same set of control code instructions but with the code being implemented a different number of times depending on the codeword length. The decoder can switch between decoding codewords of different lengths, without the need to change the stored code description information, by simply changing a code lifting factor that is indicative of codeword length and is used to control the decoding process. When decoding codewords shorter than the maximum supported codeword length some block storage locations may go unused.

摘要： A wireless terminal supports both peer to peer communications and access node based communications. The wireless terminal considers and evaluates communications link alternatives and selects between (i) communication using a peer to peer link and (ii) communications using a link with a base station serving as an access node. Received signals corresponding to each of the link alternatives are used in performing link quality determinations. In one example, a received user beacon signal from a peer wireless terminal is the received signal used for the peer to peer link evaluation and a base station beacon signal is the received signal used for the access node link evaluation. A link is selected as a function of quality determination, predicted data throughput, link maintenance energy requirements, and/or least cost routing determination information.

摘要： Different NAK signals are used to indicate different relative levels of success in regard to an unsuccessful attempt to decode a received signal. An ACK signal is used in the case of successful decoding. The device which generated and transmitted the original encoded signal receives the NAK signal and selects a portion of redundant information, e.g., additional error correction bits, to be transmitted based on the value of the NAK signal. If the NAK signal indicates a low level of decoding success indicating a relatively large number of errors in the decoded signal, a large set of redundant information is selected and transmitted. If the NAK signal indicates a relatively successful decoding, e.g., relatively few errors, a small set of redundant information is selected and transmitted. Where a small set of redundant information is transmitted new information can be transmitted with the redundant information.
