    Abstract: An encoder (300) selects (702, 1302, 1304, 1306, 1308) one or more subsets of spatially or temporally correlated transformed data coefficients, on the basis of the significance of each subset in representing the data. The encoder (300) and a complementary decoder (400) may be applied to wavelet transform encoded images (500). The encoder (300) may be implemented on a wireless to Internet gateway server (108), in order to reduce byte size of encoded images (500) sent through a wireless network (112), and reduce the amount of processing that must be performed by a wireless device (118) to decode an image or other data. The decoder (400) and/or encoder (300) may be implemented on the wireless device (118).

    Abstract: A method for generating a wavelet filter provides improved selectivity with minimal computational intensity in digital data systems (300,400). The process begins by generating an initial wavelet formed of low pass and high pass analysis filter bank (302). The next steps include obtaining an upper triangular matrix which, when multiplied by the initial wavelet, produces a product retaining the symmetry and enhancing the number of zero moment(s) of the initial wavelet (304); and obtaining a lower triangular matrix which, when multiplied by the initial wavelet, produces a product retaining the symmetry and the zero moment of the initial wavelet (306). By multiplying the upper and lower triangular matrices with the initial wavelet, an updated wavelet filter with improved selectivity is produced (308, 318).

A stationary member (6) is soldered on the first surface (8).

    Abstract: A digital data system (100) provides 1-D, 2-D and 3-D capability and multi-band channel capability. Improved filter banks are created by generating a filter bank having an analysis portion and synthesis portion and obtaining wavelet coefficients (302) for each portion. The wavelet coefficients are expressed in a format capable of canonical signed digit (CSD) representation, such as integers (302). The canonical signed digit (CSD) representation is controlled by a value, N, selected to control resolution of the CSD coding. Optimized CSD-coded wavelet coefficients are used as filters for data signals (318).

    Abstract: A frequency synthesizer is provided including a reference frequency generator coupled to one input of a phase detector. The output of the phase detector is coupled via a pair of alternatingly connected filters through a voltage controlled oscillator and a divider circuit to the remaining input of the phase detector to form a phase locked loop. The first filter of the pair is designated for operation on a main channel frequency while the remaining filter is designated for operation on a priority channel frequency. The capacitive elements of each respective filter remain fully charged up for operation on their respective frequencies and thus when such filters are alternately switched between to change frequency from the main channel to the priority channel, the capacitive elements need not be charged to new levels to accommodate such frequency change. Thus, switching between a main channel and a priority channel is accomplished in a minimal amount of time with a significant reduction in frequency synthesizer energy requirements.
