    • An improved counter wherein consecutively cascaded flip-flops of the prior art are divided into two groups. A first detector produces a first signal in response to a predetermined set of flip-flop states of the first group. A second detector produces a second signal in response to a predetermined set of flip-flop states of the second group. A third detector produces a count output in response to simultaneous existence of the first and second signals. The output from the first group is arranged in phase so that the second signal may be produced before the count output is produced, by applying an inverted output of the first group to the input of the second group.
    • 一种改进的计数器,其中先有技术的连续级联的触发器被分成两组。 第一检测器响应于第一组的预定触发器状态集合产生第一信号。 第二检测器响应于第二组的预定触发器状态集合产生第二信号。 第三检测器响应于同时存在第一和第二信号而产生计数输出。 来自第一组的输出被同相布置,使得可以在产生计数输出之前产生第二信号,通过将第一组的反相输出应用于第二组的输入。

    • A plurality of memory relays have their respective set coils connected in series with and between channel terminals of a first rough setting matrix and a first fine setting matrix, and have their respective reset coils connected in series with and between channel terminals of a second rough setting matrix and a second fine setting matrix. The timing terminals of the first and second rough setting matrices are connected to the output terminals of a rough counting relay and the timing terminals of the first and second fine setting matrixes are connected to the output terminals of a fine counting relay. These counting relays are supplied with clock pulses for counting operation by means of a clock pulse source. Each memory relay is driven to a set state in response to an output provided at a corresponding channel terminal at a time point preset in the first setting matrixes and is driven to a reset state in response to an output provided at a corresponding channel terminal at a time point preset in the second setting matrixes. Means for controlling the pulse repetition frequency of the clock pulse and for returning said counting relays and memory relays are provided and frequency control and return operation are controlled advantageously by means of said memory relays.

    • Apparatus for recording traffic events occurring at a variety of vehicular traffic passageways, such apparatus including a portable housing unit having a keyboard presenting a predetermined pattern of pushbutton switches. A plurality of interchangeable display boards, each having different vehicular traffic patterns and symbolic traffic events displayed thereon, are selectively mounted over the keyboard, and each symbolic traffic even coincides with a particular pushbutton when so mounted. Choice of a suitable display board corresponding to a particular intersection and a desired type of traffic count allows a traffic checker to complete a traffic count by merely pressing a push-button switch corresponding to each observed traffic event and its location. The portable housing includes a data processor which places a switch- and time-identified signal in its memory for each pushbutton depression and may later be plugged into a master computer for abstraction, processing, and tabulated print-out of the recorded data according to the pre-programming of the master computer.

    • A counter stage having a master section coupled to a slave section in which the transfer of signals between the master and the slave is selectively inhibited. In one embodiment of the invention, an inhibit transmission gate is logically "ANDED" with a clocked transmission gate between the master and slave sections of a counter stage. When the inhibit transmission gate is enabled, the counter stage operates normally. When the inhibit transmission gate is disabled, the states of the master and slave sections cannot change and the count in the stage does not advance. In this and other embodiments, clocking signals are continuously applied to the master-slave sections of a counting stage while transfer of data between the two sections is selectively inhibited. In still other embodiments, the clocking signals to a master-slave counter stage are selectively inhibited to prevent change in the stage.
