An inventive method is disclosed for bootstrapping a trusted client public key at the server side in a client-server model of e-commerce or distributed computer applications.

When the pulse amplitude corresponding to the respective energy is exceeded, a signal is emitted each time the pulse amplitude corresponding to a respective threshold energy is exceeded. At least one embodiment of the method permits reliable and high-quality imaging, even in image regions with high X-ray quanta rates. To this end, at least one of the threshold energies is predetermined such that it is higher than the maximum energy of the X-ray spectrum emitted by the X-ray emitter.

Clock frequency divider circuit, clock distribution circuit, clock frequency division method, and clock distribution method
To provide a clock frequency divider circuit that generates a clock signal enabling an expected proper communication in communication with a circuit operating by a clock having a different frequency. A clock frequency division circuit according to the present invention generates an output clock signal obtained by dividing a frequency of an input clock signal into N/S by subtracting (S−N) clock pulses from S clock pulses of the input clock signal based on a frequency division ratio defined as N/S. The clock frequency division circuit generates a control signal used to preferentially subtract a clock pulse at a timing other than a communication timing of data communication performed by a target circuit using the output clock signal among S clock pulses of the input clock signal. Further, it generates the output clock signal by subtracting a clock pulse of the input clock signal according to the generated control signal.
IQ mismatch correction circuit
An IQ mismatch correction circuit comprises: a correction circuit which performs a correction process to I-phase and Q-phase input signals by using one pair of first- or higher-order digital filters; two or more control circuits which independently generate two or more control variables to derive two or more coefficients of transfer functions of the digital filters; and one or more pairs of analyzing filters which change frequency characteristics of the corrected I-phase and Q-phase output signals so that the frequency characteristics is different from those of the original signals. The first control circuit measures a temporally averaged IQ phase mismatch state between the I-phase and Q-phase output signals. The second control circuit measures a temporally averaged IQ phase mismatch state between output signals on I-phase and Q-phase sides of one pair of analyzing filters. These states are fed back to the digital filters as first and second control variables, respectively.
Automatic filter-reset mechanism
In one embodiment, a (hard-drive) read channel has a (DFIR equalization) filter, whose tap coefficients are adaptively updated. A reset controller monitors an (LLR) signal generated downstream of the filter to automatically determine when to reset the filter, e.g., by reloading an initial set of user-specified tap coefficients. For LLR values, the reset controller determines to reset the filter when the reset controller detects that too many recent LLR values have confidence values that are too low. When implemented in a hard-drive read channel, the reset controller can reset the filter one or more times during read operations within a sector of the hard drive.
