An annuity provides a guaranteed rate of return for a guarantee period while at the same time providing upward adjustments to the interest rate if there is a corresponding increase in a specified referenced rate, which may be a United States Treasury rate or an interest rate that is used to settle a contract that is traded on a financial futures exchange. The guaranteed base interest rate is set at the beginning of the guarantee period, and the annuity account is credited with the base interest rate for an initial pre-defined period, which is some portion of the guarantee period. Periodically, as defined by the pre-defined period, the then-current referenced rate is compared to a base referenced rate that was defined at the establishment of the guarantee period. If the referenced rate has increased, the interest rate that will be credited to the annuity account value will increase by an amount that is based on the amount of increase in the referenced rate. If the referenced rate has not changed or has decreased, the interest rate that will be credited to the annuity account value will be the guaranteed base interest rate that was set at the beginning of the guarantee period.

The inventive embodiment provides a method and a device for transmitting and receiving a client signal in optical transport network, belonging to the field of optical transport network. The transmitting method comprises: mapping the received client signal to a container OTU-N with a variable rate, which is N times the preset reference rate grade, wherein N is a configurable positive integer according to requirement; dividing the container OTU-N with the variable rate into N photon channel transmission units OTUsub according to columns, the rate of each OTUsub being equal to the reference rate grade; modulating the N photon channel transmission units OTUsub to a one-channel or multi-channel optical carrier; and transmitting the one-channel or multi-channel optical carriers on the same optical fiber. The method provided by the invention is adaptive to the change in spectral bandwidth of an optical layer by mapping the client signal to the container OTU-N with the variable rate and by transmitting the OTU-N through the same optical fiber, thereby realizing optimized configuration of the bandwidth resources of the optical transport network.

Base stations control the transmission rate that is used by UE (user equipment) to forward them information. A UE periodically forwards a rate request to a base station if the UE needs to have its data transmission rate to the base station increased or decreased, and the base station responds with a rate command. An error can occur in the transmission of the rate command, such that a rate Rnb transmitted by the base station and detected by the UE as Rue may not match. Various schemes are proposed for reducing and correcting such transmission errors. A first scheme involves periodically resetting the transmission rate of the base station and UE with a reference rate. Second to fourth schemes involve periodically comparing the transmission rates of the base station and UE, and replacing the rate of the UE if they differ. A fifth scheme involves a filtering of the feedback command in order to reduce the impact of error propagation. A sixth scheme, which may be used separately or in conjunction with any of the foregoing schemes, involves adjusting a power offset with a repetition factor. All of the schemes are modified during a soft handover of the UE from the base station to a new base station.

A self-calibrating gyroscope system provides improved estimates of, and compensation or calibration for, scale factor errors and bias errors. The gyroscope system employs a plurality of gyroscope units having sense or input axes in a mutually non-parallel arrangement. A Mode Reversal technique is used to obtain an estimate of bias error for a selected gyroscope. A Random Closed-Loop Scale Factor technique is used to obtain an estimate of scale factor error for a selected gyroscope. Because the Mode Reversal technique temporarily disrupts operation of the affected gyroscope, each of the gyroscopes may be taken offline temporarily, in turn, for calibration, and thereafter returned to normal operation. Because at least one redundant gyroscope is provided, when a selected gyroscope is offline, rate information from the remaining operating gyroscopes can be used to derive a reference rate about the axis of the offline gyroscope.

An improved method is disclosed for the encoding phase for Wavelet-based compression of digital data representing an object or image. Subband decomposition transforms the data into hierarchical tree data. Two terms are precomputed: the highest bit-plane in which any descendant of a node v has a non-zero bit (B₁(v) and the highest bit-plane in which any indirect descendant (grandchild and beyond) becomes significant (B₂(v). Node traversal is initiated but its extent is limited by a fixed bit-budget. The number of bits emitted by a node as a function of the bit-plane are counted through to the last bit-plane which exhausts the bit-budget. The user can predetermine the coefficient, bit-plane and specific bit at which the algorithm will halt. The tree structure is read only once, thus greatly accelereating the encoding and reducing the memory reference rate by a factor of 2 or more. Accumulators for each of the stacked bit-planes are provided which are incremented as each said Wavelet coefficient is produced, by the number of bits that the coefficient adds to the relevant bit-plane.
