Patent number: 7349821Abstract: A device and method for conversion of bi-directional signals using controlled dual value up/down counters uses a plurality of cascaded up/down counters chained together to alter the ratio of a maximum coefficient of N to N+1 for the first counter in the cascade of counters. The output count signal of each counter is connected to the clock signal input of the next counter. The signal to be converted is input to the first counter in the chain and each input pulse increments or decrements a count value for the counter until a maximum coefficient or zero is reached at which point a count pulse is output of the counter and it is then reset to zero or the maximum coefficient at the next input pulse depending on whether a direction input is high or low circuit.Type: GrantFiled: September 3, 2004Date of Patent: March 25, 2008Assignee: Miranova Systems, Inc.Inventor: Alexander R.

Patent number: 7336756Abstract: A signal converter is comprised of a plurality of counters (“macro-counters”). In turn, each of the macro-counters is comprised of a plurality of single-bit counters (“micro-counters”) that are adapted to receive configuration data in the form of bit fields. The configuration data is comprised of data corresponding to a plurality of coefficients and of data for grouping the micro-counters into the macro-counters. The coefficients are derived from an input signal/output signal ratio of the converter, and control the manner by which the macro-counters generate the output signal. Thus the converter can be programmed by an end-user in the field.Type: GrantFiled: October 25, 2005Date of Patent: February 26, 2008Assignee: Miranova Systems, Inc.Inventor: Alexander R. Stephens

Patent number: 6789041Abstract: An apparatus and method for use in conversion of bidirectional signals are provide. Some embodiments, use dual-value up/down counters chained together to alter the ratio of input to output signals between N and N+1 such that an averaged output is a non-integral multiple of the input. The maximum value for each counter can be N or N+1 according to the next counter. An output signal is asserted when the maximum value is reached, and a count signal is output on the next up count, resetting the counter to zero. An output signal is asserted when the counter equals zero, and a count signal is output on the next down count, setting the counter to the currently selected maximum value. Direction signal is common to counters, and count output is count input of the next counter. Output count of first counter is final circuit count output.Type: GrantFiled: May 7, 2002Date of Patent: September 7, 2004Assignee: Miranova Systems, Inc.Inventor: Alexander R. Stephens
