A numeric counter oscillator is disclosed comprising a quotient accumulator and a remainder accumulator. The quotient accumulator has a programmable input for receiving a QUOTIENT value, a reference clock input and a multi-bit output. The output is adapted for transmitting an output value OUT representing an accumulated quotient sum. The multi-bit output increments by a predetermined amount in response to each reference clock period. The remainder accumulator comprises programmable inputs for receiving respective REMAINDER and DIVISOR values, a a reference clock input and a multi-bit output representing an accumulated digital remainder sum less than a predefined digital integer. The remainder accumulator further comprises a comparator having a first input for receiving a programmed divisor value, and a second input for receiving the remainder accumulator multi-bit output. The comparator is operative to generate an increment carry signal for application to the quotient accumulator when the remainder multi-bit output reaches the predefined integer value.

A pattern generator for use in a memory tester to provide packet address and data signals to a packet-based memory-under-test is disclosed. The pattern generator includes an address source for generating an external packet memory address signal. The external packet memory address signal represents a plurality of addressable memory elements in the memory-under-test. A plurality of data generators are disposed in parallel relationship and coupled to the output of the address source to receive at least a portion of the packet memory address signal. Each of the data generators has logic operative to derive an internal address from the packet address. The internal address corresponds to an individual memory element within the memory under test. A sequencer is disposed at the outputs of the data generators to distribute the data generator outputs in a packet waveform for application to the memory-under-test.
摘要:
The invention relates to a sway brace on rail vehicles. The aim of the invention is to find a solution in which the effort and expense needed to produce the sprung sway braces can be reduced and the transverse forces and the resultant wear occurring on deflection can be reduced to the minimum. This is achieved by the invention in that one end of the sprung sway braces in a special design is arranged in a support with defined guide surfaces while the other end is secured to the piston of a hydraulic cylinder via an axial rocker beating. In addition, there is a disc spring column above the sway brace.
